Death – Wikipedia

Irreversible cessation of all biological functions that sustain organisms

Death is the irreversible cessation of all biological functions that sustain an organism.[1] For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including brainstem, and[2][3] brain death is sometimes used as a legal definition of death.[4] The remains of a former organism normally begin to decompose shortly after death. Death is an inevitable process that eventually occurs in almost all organisms.

Death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die. As of the early 21st century, over 150,000 humans die each day, with ageing being by far the most common cause of death.[citation needed]

Many cultures and religions have the idea of an afterlife, and also may hold the idea of judgement of good and bad deeds in one's life (heaven, hell, karma).

The concept of death is a key to human understanding of the phenomenon.[5] There are many scientific approaches and various interpretations of the concept. Additionally, the advent of life-sustaining therapy and the numerous criteria for defining death from both a medical and legal standpoint, have made it difficult to create a single unifying definition.

One of the challenges in defining death is in distinguishing it from life. As a point in time, death would seem to refer to the moment at which life ends. Determining when death has occurred is difficult, as cessation of life functions is often not simultaneous across organ systems.[6] Such determination, therefore, requires drawing precise conceptual boundaries between life and death. This is difficult, due to there being little consensus on how to define life.

It is possible to define life in terms of consciousness. When consciousness ceases, an organism can be said to have died. One of the flaws in this approach is that there are many organisms that are alive but probably not conscious (for example, single-celled organisms). Another problem is in defining consciousness, which has many different definitions given by modern scientists, psychologists and philosophers. Additionally, many religious traditions, including Abrahamic and Dharmic traditions, hold that death does not (or may not) entail the end of consciousness. In certain cultures, death is more of a process than a single event. It implies a slow shift from one spiritual state to another.[7]

Other definitions for death focus on the character of cessation of organismic functioning and a human death which refers to irreversible loss of personhood. More specifically, death occurs when a living entity experiences irreversible cessation of all functioning.[8] As it pertains to human life, death is an irreversible process where someone loses their existence as a person.[8]

Historically, attempts to define the exact moment of a human's death have been subjective, or imprecise. Death was once defined as the cessation of heartbeat (cardiac arrest) and of breathing, but the development of CPR and prompt defibrillation have rendered that definition inadequate because breathing and heartbeat can sometimes be restarted. This type of death where circulatory and respiratory arrest happens is known as the circulatory definition of death (DCDD). Proponents of the DCDD believe that this definition is reasonable because a person with permanent loss of circulatory and respiratory function should be considered dead.[9] Critics of this definition state that while cessation of these functions may be permanent, it does not mean the situation is irreversible, because if CPR was applied, the person could be revived.[9] Thus, the arguments for and against the DCDD boil down to a matter of defining the actual words "permanent" and "irreversible," which further complicates the challenge of defining death. Furthermore, events which were causally linked to death in the past no longer kill in all circumstances; without a functioning heart or lungs, life can sometimes be sustained with a combination of life support devices, organ transplants and artificial pacemakers.

Today, where a definition of the moment of death is required, doctors and coroners usually turn to "brain death" or "biological death" to define a person as being dead; people are considered dead when the electrical activity in their brain ceases. It is presumed that an end of electrical activity indicates the end of consciousness. Suspension of consciousness must be permanent, and not transient, as occurs during certain sleep stages, and especially a coma. In the case of sleep, EEGs can easily tell the difference.

The category of "brain death" is seen as problematic by some scholars. For instance, Dr. Franklin Miller, senior faculty member at the Department of Bioethics, National Institutes of Health, notes: "By the late 1990s... the equation of brain death with death of the human being was increasingly challenged by scholars, based on evidence regarding the array of biological functioning displayed by patients correctly diagnosed as having this condition who were maintained on mechanical ventilation for substantial periods of time. These patients maintained the ability to sustain circulation and respiration, control temperature, excrete wastes, heal wounds, fight infections and, most dramatically, to gestate fetuses (in the case of pregnant "brain-dead" women)."[10]

While "brain death" is viewed as problematic by some scholars, there are certainly proponents of it that believe this definition of death is the most reasonable for distinguishing life from death. The reasoning behind the support for this definition is that brain death has a set of criteria that is reliable and reproducible.[11] Also, the brain is crucial in determining our identity or who we are as human beings. The distinction should be made that "brain death" cannot be equated with one who is in a vegetative state or coma, in that the former situation describes a state that is beyond recovery.[11]

Those people maintaining that only the neo-cortex of the brain is necessary for consciousness sometimes argue that only electrical activity should be considered when defining death. Eventually it is possible that the criterion for death will be the permanent and irreversible loss of cognitive function, as evidenced by the death of the cerebral cortex. All hope of recovering human thought and personality is then gone given current and foreseeable medical technology. At present, in most places the more conservative definition of death irreversible cessation of electrical activity in the whole brain, as opposed to just in the neo-cortex has been adopted (for example the Uniform Determination Of Death Act in the United States). In 2005, the Terri Schiavo case brought the question of brain death and artificial sustenance to the front of American politics.

Even by whole-brain criteria, the determination of brain death can be complicated. EEGs can detect spurious electrical impulses, while certain drugs, hypoglycemia, hypoxia, or hypothermia can suppress or even stop brain activity on a temporary basis. Because of this, hospitals have protocols for determining brain death involving EEGs at widely separated intervals under defined conditions.

In the past, adoption of this whole-brain definition was a conclusion of the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research in 1980.[12] They concluded that this approach to defining death sufficed in reaching a uniform definition nationwide. A multitude of reasons were presented to support this definition including: uniformity of standards in law for establishing death; consumption of a family's fiscal resources for artificial life support; and legal establishment for equating brain death with death in order to proceed with organ donation.[13]

Aside from the issue of support of or dispute against brain death, there is another inherent problem in this categorical definition: the variability of its application in medical practice. In 1995, the American Academy of Neurology (AAN), established a set of criteria that became the medical standard for diagnosing neurologic death. At that time, three clinical features had to be satisfied in order to determine "irreversible cessation" of the total brain including: coma with clear etiology, cessation of breathing, and lack of brainstem reflexes.[14] This set of criteria was then updated again most recently in 2010, but substantial discrepancies still remain across hospitals and medical specialties.[14]

The problem of defining death is especially imperative as it pertains to the dead donor rule, which could be understood as one of the following interpretations of the rule: there must be an official declaration of death in a person before starting organ procurement or that organ procurement cannot result in death of the donor.[9] A great deal of controversy has surrounded the definition of death and the dead donor rule. Advocates of the rule believe the rule is legitimate in protecting organ donors while also countering against any moral or legal objection to organ procurement. Critics, on the other hand, believe that the rule does not uphold the best interests of the donors and that the rule does not effectively promote organ donation.[9]

Signs of death or strong indications that a warm-blooded animal is no longer alive are:

The stages that follow after death are:

The death of a person has legal consequences that may vary between different jurisdictions.A death certificate is issued in most jurisdictions, either by a doctor, or by an administrative office upon presentation of a doctor's declaration of death.

There are many anecdotal references to people being declared dead by physicians and then "coming back to life", sometimes days later in their own coffin, or when embalming procedures are about to begin. From the mid-18th century onwards, there was an upsurge in the public's fear of being mistakenly buried alive,[15] and much debate about the uncertainty of the signs of death. Various suggestions were made to test for signs of life before burial, ranging from pouring vinegar and pepper into the corpse's mouth to applying red hot pokers to the feet or into the rectum.[16] Writing in 1895, the physician J.C. Ouseley claimed that as many as 2,700 people were buried prematurely each year in England and Wales, although others estimated the figure to be closer to 800.[17]

In cases of electric shock, cardiopulmonary resuscitation (CPR) for an hour or longer can allow stunned nerves to recover, allowing an apparently dead person to survive. People found unconscious under icy water may survive if their faces are kept continuously cold until they arrive at an emergency room.[18] This "diving response", in which metabolic activity and oxygen requirements are minimal, is something humans share with cetaceans called the mammalian diving reflex.[18]

As medical technologies advance, ideas about when death occurs may have to be re-evaluated in light of the ability to restore a person to vitality after longer periods of apparent death (as happened when CPR and defibrillation showed that cessation of heartbeat is inadequate as a decisive indicator of death). The lack of electrical brain activity may not be enough to consider someone scientifically dead. Therefore, the concept of information-theoretic death[19] has been suggested as a better means of defining when true death occurs, though the concept has few practical applications outside the field of cryonics.

There have been some scientific attempts to bring dead organisms back to life, but with limited success.[20]

The leading cause of human death in developing countries is infectious disease. The leading causes in developed countries are atherosclerosis (heart disease and stroke), cancer, and other diseases related to obesity and aging. By an extremely wide margin, the largest unifying cause of death in the developed world is biological aging,[21] leading to various complications known as aging-associated diseases. These conditions cause loss of homeostasis, leading to cardiac arrest, causing loss of oxygen and nutrient supply, causing irreversible deterioration of the brain and other tissues. Of the roughly 150,000 people who die each day across the globe, about two thirds die of age-related causes.[21] In industrialized nations, the proportion is much higher, approaching 90%.[21] With improved medical capability, dying has become a condition to be managed. Home deaths, once commonplace, are now rare in the developed world.

In developing nations, inferior sanitary conditions and lack of access to modern medical technology makes death from infectious diseases more common than in developed countries. One such disease is tuberculosis, a bacterial disease which killed 1.8M people in 2015.[23] Malaria causes about 400900M cases of fever and 13M deaths annually.[24] AIDS death toll in Africa may reach 90100M by 2025.[25][26]

According to Jean Ziegler (United Nations Special Reporter on the Right to Food, 2000 Mar 2008), mortality due to malnutrition accounted for 58% of the total mortality rate in 2006. Ziegler says worldwide approximately 62M people died from all causes and of those deaths more than 36M died of hunger or diseases due to deficiencies in micronutrients.[27]

Tobacco smoking killed 100million people worldwide in the 20th century and could kill 1billion people around the world in the 21st century, a World Health Organization report warned.[22]

Many leading developed world causes of death can be postponed by diet and physical activity, but the accelerating incidence of disease with age still imposes limits on human longevity. The evolutionary cause of aging is, at best, only just beginning to be understood. It has been suggested that direct intervention in the aging process may now be the most effective intervention against major causes of death.[28]

Selye proposed a unified non-specific approach to many causes of death. He demonstrated that stress decreases adaptability of an organism and proposed to describe the adaptability as a special resource, adaptation energy. The animal dies when this resource is exhausted.[29] Selye assumed that the adaptability is a finite supply, presented at birth. Later on, Goldstone proposed the concept of a production or income of adaptation energy which may be stored (up to a limit), as a capital reserve of adaptation.[30] In recent works, adaptation energy is considered as an internal coordinate on the "dominant path" in the model of adaptation. It is demonstrated that oscillations of well-being appear when the reserve of adaptability is almost exhausted.[31]

In 2012, suicide overtook car crashes for leading causes of human injury deaths in the U.S., followed by poisoning, falls, and murder.[32] Causes of death are different in different parts of the world. In high-income and middle income countries nearly half up to more than two thirds of all people live beyond the age of 70 and predominantly die of chronic diseases. In low-income countries, where less than one in five of all people reach the age of 70, and more than a third of all deaths are among children under 15, people predominantly die of infectious diseases.[33]

An autopsy, also known as a postmortem examination or an obduction, is a medical procedure that consists of a thorough examination of a human corpse to determine the cause and manner of a person's death and to evaluate any disease or injury that may be present. It is usually performed by a specialized medical doctor called a pathologist.

Autopsies are either performed for legal or medical purposes. A forensic autopsy is carried out when the cause of death may be a criminal matter, while a clinical or academic autopsy is performed to find the medical cause of death and is used in cases of unknown or uncertain death, or for research purposes. Autopsies can be further classified into cases where external examination suffices, and those where the body is dissected and an internal examination is conducted. Permission from next of kin may be required for internal autopsy in some cases. Once an internal autopsy is complete the body is generally reconstituted by sewing it back together. Autopsy is important in a medical environment and may shed light on mistakes and help improve practices.

A necropsy, which is not always a medical procedure, was a term previously used to describe an unregulated postmortem examination. In modern times, this term is more commonly associated with the corpses of animals.

Senescence refers to a scenario when a living being is able to survive all calamities, but eventually dies due to causes relating to old age. Animal and plant cells normally reproduce and function during the whole period of natural existence, but the aging process derives from deterioration of cellular activity and ruination of regular functioning. Aptitude of cells for gradual deterioration and mortality means that cells are naturally sentenced to stable and long-term loss of living capacities, even despite continuing metabolic reactions and viability. In the United Kingdom, for example, nine out of ten of all the deaths that occur on a daily basis relates to senescence, while around the world it accounts for two-thirds of 150,000 deaths that take place daily.[34][full citation needed]

Almost all animals who survive external hazards to their biological functioning eventually die from biological aging, known in life sciences as "senescence". Some organisms experience negligible senescence, even exhibiting biological immortality. These include the jellyfish Turritopsis dohrnii,[35] the hydra, and the planarian. Unnatural causes of death include suicide and predation. From all causes, roughly 150,000 people die around the world each day.[21] Of these, two thirds die directly or indirectly due to senescence, but in industrialized countries such as the United States, the United Kingdom, and Germany the rate approaches 90% (i.e., nearly nine out of ten of all deaths are related to senescence).[21]

Physiological death is now seen as a process, more than an event: conditions once considered indicative of death are now reversible.[36] Where in the process a dividing line is drawn between life and death depends on factors beyond the presence or absence of vital signs. In general, clinical death is neither necessary nor sufficient for a determination of legal death. A patient with working heart and lungs determined to be brain dead can be pronounced legally dead without clinical death occurring.

Cryonics (from Greek 'kryos-' meaning 'icy cold') is the low-temperature preservation of animals and humans who cannot be sustained by contemporary medicine, with the hope that healing and resuscitation may be possible in the future.[37][38]

Cryopreservation of people or large animals is not reversible with current technology. The stated rationale for cryonics is that people who are considered dead by current legal or medical definitions may not necessarily be dead according to the more stringent information-theoretic definition of death.[19][39]

Some scientific literature is claimed to support the feasibility of cryonics.[40] Medical science and cryobiologists generally regards cryonics with skepticism.[41]

"One of medicine's new frontiers: treating the dead", recognizes that cells that have been without oxygen for more than five minutes die,[42] not from lack of oxygen, but rather when their oxygen supply is resumed. Therefore, practitioners of this approach, e.g., at the Resuscitation Science institute at the University of Pennsylvania, "aim to reduce oxygen uptake, slow metabolism and adjust the blood chemistry for gradual and safe reperfusion."[43] Moreover, there is an organ perfusion system under development that can restore, i.e. on the cellular level, multiple vital (pig) organs one hour after death (during which the body had prolonged warm ischaemia),[44][45] and a similar method/system, reported in 2019, for partially reviving (pig) brains hours after death.[44][46] It showed that "the process of cell death is a gradual, stepwise process and that some of those processes can be either postponed, preserved or even reversed".[47] Such methods or systems could be developed further to be used to preserve donor organs or for revival in medical emergencies by buying "more time for doctors to treat people whose bodies were starved of oxygen, such as those who died from drowning or heart attacks".[44]

Life extension refers to an increase in maximum or average lifespan, especially in humans, by slowing down or reversing the processes of aging through anti-aging measures. Despite the fact that aging is by far the most common cause of death worldwide, it is socially mostly ignored as such and seen as "necessary" and "inevitable" anyway, which is why little money is spent on research into anti-aging therapies, a phenomenon known as the pro-aging trance.[21]

Average lifespan is determined by vulnerability to accidents and age or lifestyle-related afflictions such as cancer, or cardiovascular disease. Extension of average lifespan can be achieved by good diet, exercise and avoidance of hazards such as smoking. Maximum lifespan is also determined by the rate of aging for a species inherent in its genes. Currently, the only widely recognized method of extending maximum lifespan is calorie restriction. Theoretically, extension of maximum lifespan can be achieved by reducing the rate of aging damage, by periodic replacement of damaged tissues, or by molecular repair or rejuvenation of deteriorated cells and tissues.

A United States poll found that religious people and irreligious people, as well as men and women and people of different economic classes have similar rates of support for life extension, while Africans and Hispanics have higher rates of support than white people.[48] 38 percent of the polled said they would desire to have their aging process cured.

Researchers of life extension are a subclass of biogerontologists known as "biomedical gerontologists". They try to understand the nature of aging and they develop treatments to reverse aging processes or to at least slow them down, for the improvement of health and the maintenance of youthful vigor at every stage of life. Those who take advantage of life extension findings and seek to apply them upon themselves are called "life extensionists" or "longevists". The primary life extension strategy currently is to apply available anti-aging methods in the hope of living long enough to benefit from a complete cure to aging once it is developed.

Before about 1930, most people in Western countries died in their own homes, surrounded by family, and comforted by clergy, neighbors, and doctors making house calls.[51] By the mid-20th century, half of all Americans died in a hospital.[52] By the start of the 21st century, only about 2025% of people in developed countries died outside of a medical institution.[52][53][54] The shift away from dying at home towards dying in a professional medical environment has been termed the "Invisible Death".[52] This shift occurred gradually over the years, until most deaths now occur outside the home.[55]

Death studies is a field within psychology.[56] Many people are afraid of dying. Discussing, thinking about, or planning for their own deaths causes them discomfort. This fear may cause them to put off financial planning, preparing a will and testament, or requesting help from a hospice organization.

Different people have different responses to the idea of their own deaths. Philosopher Galen Strawson writes that the death that many people wish for is an instant, painless, unexperienced annihilation.[57] In this unlikely scenario, the person dies without realizing it and without being able to fear it. One moment the person is walking, eating, or sleeping, and the next moment, the person is dead. Strawson reasons that this type of death would not take anything away from the person, as he believes that a person cannot have a legitimate claim to ownership in the future.[57][58]

In society, the nature of death and humanity's awareness of its own mortality has for millennia been a concern of the world's religious traditions and of philosophical inquiry. This includes belief in resurrection or an afterlife (associated with Abrahamic religions), reincarnation or rebirth (associated with Dharmic religions), or that consciousness permanently ceases to exist, known as eternal oblivion (associated with Secular humanism).[59]

Commemoration ceremonies after death may include various mourning, funeral practices and ceremonies of honouring the deceased. The physical remains of a person, commonly known as a corpse or body, are usually interred whole or cremated, though among the world's cultures there are a variety of other methods of mortuary disposal. In the English language, blessings directed towards a dead person include rest in peace (originally the Latin requiescat in pace), or its initialism RIP.

Death is the center of many traditions and organizations; customs relating to death are a feature of every culture around the world. Much of this revolves around the care of the dead, as well as the afterlife and the disposal of bodies upon the onset of death. The disposal of human corpses does, in general, begin with the last offices before significant time has passed, and ritualistic ceremonies often occur, most commonly interment or cremation. This is not a unified practice; in Tibet, for instance, the body is given a sky burial and left on a mountain top. Proper preparation for death and techniques and ceremonies for producing the ability to transfer one's spiritual attainments into another body (reincarnation) are subjects of detailed study in Tibet.[60] Mummification or embalming is also prevalent in some cultures, to retard the rate of decay.

Legal aspects of death are also part of many cultures, particularly the settlement of the deceased estate and the issues of inheritance and in some countries, inheritance taxation.

Capital punishment is also a culturally divisive aspect of death. In most jurisdictions where capital punishment is carried out today, the death penalty is reserved for premeditated murder, espionage, treason, or as part of military justice. In some countries, sexual crimes, such as adultery and sodomy, carry the death penalty, as do religious crimes such as apostasy, the formal renunciation of one's religion. In many retentionist countries, drug trafficking is also a capital offense. In China, human trafficking and serious cases of corruption are also punished by the death penalty. In militaries around the world courts-martial have imposed death sentences for offenses such as cowardice, desertion, insubordination, and mutiny.[61]

Death in warfare and in suicide attack also have cultural links, and the ideas of dulce et decorum est pro patria mori, mutiny punishable by death, grieving relatives of dead soldiers and death notification are embedded in many cultures. Recently in the western world, with the increase in terrorism following the September 11 attacks, but also further back in time with suicide bombings, kamikaze missions in World War II and suicide missions in a host of other conflicts in history, death for a cause by way of suicide attack, and martyrdom have had significant cultural impacts.

Suicide in general, and particularly euthanasia, are also points of cultural debate. Both acts are understood very differently in different cultures. In Japan, for example, ending a life with honor by seppuku was considered a desirable death, whereas according to traditional Christian and Islamic cultures, suicide is viewed as a sin. Death is personified in many cultures, with such symbolic representations as the Grim Reaper, Azrael, the Hindu god Yama and Father Time.

In Brazil, a human death is counted officially when it is registered by existing family members at a cartrio, a government-authorized registry. Before being able to file for an official death, the deceased must have been registered for an official birth at the cartrio. Though a Public Registry Law guarantees all Brazilian citizens the right to register deaths, regardless of their financial means, of their family members (often children), the Brazilian government has not taken away the burden, the hidden costs and fees, of filing for a death. For many impoverished families, the indirect costs and burden of filing for a death lead to a more appealing, unofficial, local, cultural burial, which in turn raises the debate about inaccurate mortality rates.[63]

Talking about death and witnessing it is a difficult issue with most cultures. Western societies may like to treat the dead with the utmost material respect, with an official embalmer and associated rites. Eastern societies (like India) may be more open to accepting it as a fait accompli, with a funeral procession of the dead body ending in an open-air burning-to-ashes of the same.

Much interest and debate surround the question of what happens to one's consciousness as one's body dies. The belief in the permanent loss of consciousness after death is often called eternal oblivion. Belief that the stream of consciousness is preserved after physical death is described by the term afterlife. Neither are likely to ever be confirmed without the ponderer having to actually die.

After death, the remains of a former organism become part of the biogeochemical cycle, during which animals may be consumed by a predator or a scavenger.[64] Organic material may then be further decomposed by detritivores, organisms which recycle detritus, returning it to the environment for reuse in the food chain, where these chemicals may eventually end up being consumed and assimilated into the cells of an organism. Examples of detritivores include earthworms, woodlice and dung beetles.

Microorganisms also play a vital role, raising the temperature of the decomposing matter as they break it down into yet simpler molecules. Not all materials need to be fully decomposed. Coal, a fossil fuel formed over vast tracts of time in swamp ecosystems, is one example.

Contemporary evolutionary theory sees death as an important part of the process of natural selection.[65] It is considered that organisms less adapted to their environment are more likely to die having produced fewer offspring, thereby reducing their contribution to the gene pool. Their genes are thus eventually bred out of a population, leading at worst to extinction and, more positively, making the process possible, referred to as speciation. Frequency of reproduction plays an equally important role in determining species survival: an organism that dies young but leaves numerous offspring displays, according to Darwinian criteria, much greater fitness than a long-lived organism leaving only one.

Extinction is the cessation of existence of a species or group of taxa, reducing biodiversity. The moment of extinction is generally considered to be the death of the last individual of that species (although the capacity to breed and recover may have been lost before this point). Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where species presumed extinct abruptly "reappear" (typically in the fossil record) after a period of apparent absence. New species arise through the process of speciation, an aspect of evolution. New varieties of organisms arise and thrive when they are able to find and exploit an ecological niche and species become extinct when they are no longer able to survive in changing conditions or against superior competition.

Inquiry into the evolution of aging aims to explain why so many living things and the vast majority of animals weaken and die with age (exceptions include Hydra and the jellyfish Turritopsis dohrnii, which research shows to be biologically immortal). The evolutionary origin of senescence remains one of the fundamental puzzles of biology. Gerontology specializes in the science of human aging processes.

Organisms showing only asexual reproduction (e.g. bacteria, some protists, like the euglenoids and many amoebozoans) and unicellular organisms with sexual reproduction (colonial or not, like the volvocine algae Pandorina and Chlamydomonas) are "immortal" at some extent, dying only due to external hazards, like being eaten or meeting with a fatal accident. In multicellular organisms (and also in multinucleate ciliates),[67] with a Weismannist development, that is, with a division of labor between mortal somatic (body) cells and "immortal" germ (reproductive) cells, death becomes an essential part of life, at least for the somatic line.[68]

The Volvox algae are among the simplest organisms to exhibit that division of labor between two completely different cell types, and as a consequence include death of somatic line as a regular, genetically regulated part of its life history.[68][69]

In Buddhist doctrine and practice, death plays an important role. Awareness of death was what motivated Prince Siddhartha to strive to find the "deathless" and finally to attain enlightenment. In Buddhist doctrine, death functions as a reminder of the value of having been born as a human being. Being reborn as a human being is considered the only state in which one can attain enlightenment. Therefore, death helps remind oneself that one should not take life for granted. The belief in rebirth among Buddhists does not necessarily remove death anxiety, since all existence in the cycle of rebirth is considered filled with suffering, and being reborn many times does not necessarily mean that one progresses.[70]

Death is part of several key Buddhist tenets, such as the Four Noble Truths and dependent origination.[70]

While there are different sects of Christianity with different branches of belief; the overarching ideology on death grows from the knowledge of afterlife. Meaning after death the individual will undergo a separation from mortality to immortality; their soul leaves the body entering a realm of spirits. Following this separation of body and spirit (i.e. death) resurrection will occur.[71] Representing the same transformation Jesus Christ embodied after his body was placed in the tomb for three days. Like Him, each person's body will be resurrected reuniting the spirit and body in a perfect form.[72] This process allows the individuals soul to withstand death and transform into life after death.

In Hindu texts, death is described as the individual eternal spiritual jiva-atma (soul or conscious self) exiting the current temporary material body. The soul exits this body when the body can no longer sustain the conscious self (life), which may be due to mental or physical reasons, or more accurately, the inability to act on one's kama (material desires). During conception, the soul enters a compatible new body based on the remaining merits and demerits of one's karma (good/bad material activities based on dharma) and the state of one's mind (impressions or last thoughts) at the time of death.

Usually the process of reincarnation (soul's transmigration) makes one forget all memories of one's previous life. Because nothing really dies and the temporary material body is always changing, both in this life and the next, death means forgetfulness of one's previous experiences (previous material identity).

Material existence is described as being full of miseries arising from birth, disease, old age, death, mind, weather, etc. To conquer samsara (the cycle of death and rebirth) and become eligible for one of the different types of moksha (liberation), one has to first conquer kama (material desires) and become self-realized. The human form of life is most suitable for this spiritual journey, especially with the help of sadhu (self-realized saintly persons), sastra (revealed spiritual scriptures), and guru (self-realized spiritual masters), given all three are in agreement.

There are a variety of beliefs about the afterlife within Judaism, but none of them contradict the preference of life over death. This is partially because death puts a cessation to the possibility of fulfilling any commandments.[citation needed]

The word "death" comes from Old English da, which in turn comes from Proto-Germanic *dauuz (reconstructed by etymological analysis). This comes from the Proto-Indo-European stem *dheu- meaning the "process, act, condition of dying".[73]

The concept and symptoms of death, and varying degrees of delicacy used in discussion in public forums, have generated numerous scientific, legal, and socially acceptable terms or euphemisms. When a person has died, it is also said they have "passed away", "passed on", "expired", or "gone", among other socially accepted, religiously specific, slang, and irreverent terms.

As a formal reference to a dead person, it has become common practice to use the participle form of "decease", as in "the deceased"; another noun form is "decedent".

Bereft of life, the dead person is a "corpse", "cadaver", "body", "set of remains" or, when all flesh is gone, a "skeleton". The terms "carrion" and "carcass" are also used, usually for dead non-human animals. The ashes left after a cremation are lately called "cremains".

Challenges and Successes of Dealing with COVID-19 in India | RRTM – Dove Medical Press

Introduction

The World Health Organization (WHO) affirmed COVID-19 as a pandemic on 11 March 2020 but earlier to this the Chinese government confirmed the first outbreak of Coronavirus disease 2019 (COVID-19) in Wuhan on 31December 2019. The state-wise lockdown, which was imposed in India due to the second wave of the novel coronavirus pandemic, affected people belonging to every economic stratum. In India, till now (9 July 2021), there have been 30,752,950 confirmed cases of COVID-19 with 405,939 deaths reported to the WHO. COVID-19 cases are rapidly rising globally of which the first case was registered on 21February 2020 in Italy. Meanwhile in India, case numbers have risen, and community transmission was officially declared by government in October 2020. Life is deeply affected by COVID-19 even for the ones who are not infected as isolation, contact restrictions and economic shutdown have changed the social and economic scenario of India. Vast populations and crowded settlements have increased the number of cases in China, Europe, USA and India. Countries with dense populations and robust travel history will increase the problem of decision-making authorities if testing is limited or disproportionate. The WHO has made projections of 3.5 beds per 1000 population1 but many countries have only 1.3 beds per 1000 population in hospitals which is again the concern of government. As the pandemic is growing in stages, this review assesses the prospects these stages might have on the Indian population as it highlights some key challenges for treatment and research related to antiviral drugs.

Cases were initially spread by migrants, overseas visitors, and some others who were in contact with these infected persons, and to control this spread lockdowns were called by various countries including India. The situation seemed to be under control due to the lockdown, but due to a religious gathering in New Delhi, which led to the human-to-human transmission of COVID-19, a sudden horrific increase in COVID-19 cases occurred. Initially, most individuals who came into contact with such infected individuals were unaware of the effects of the virus in their bodies. To sustain the countrys economy, unlocks were called by the Indian Government in multiple phases, therefore, the persons who were unaware that they were carrying the virus spread it many more healthy persons. However, preventive measures including social distancing, quarantine and isolation techniques had been taken globally and have proven effective in the absence of drug treatments and other approaches. Adults (ages 50 and over), and people with comorbidities can have higher chances of becoming severely ill with COVID-19 and contribute to the largest portion of all deaths worldwide among infected cases.2,3

In India, the overall numbers dying constantly increased, amongst them a lot of the demise circumstances pointed to a particular age-group of aged folks.4 In India, among the total COVID-19 cases (30,752,950) and total deaths (405,939) till 9 July 2021, 90% were older than 40 years. Overall, people in the age group of 40 years and greater, have suffered the major impact of the current COVID-19 eruption and are more vulnerable.5,6 The massive loss of people in the workforce is likely to have devastating social and economic consequences.

The basic measures adopted worldwide include maintenance of hand hygiene, avoiding close contact, using face masks, disinfection and monitoring health.7 The ongoing COVID-19 pandemic has once again brought the benefits of appropriate hand hygiene (hand washing and use of alcohol-based hand-sanitizers) to the centre stage. Since hand washing is not a feasible and available option at all times, the use of alcohol-based hand-sanitizers (hand rubs) has been recommended by health organizations, when hands are not visibly soiled. These sanitizers act as a powerful, fast acting and effective solution with broad antimicrobial range.7 Hands act as a medium for exchange of microbes between the organism and its environment. The skin of the hands harbours a variety of organisms ranging from commensal to potential pathogens. Therefore, adequate hand hygiene can greatly reduce disease transmission. The most commonly used agents for hand disinfection are hand-sanitizers. There are two major types of preparations available: alcohol-based and alcohol-free. The alcohol-based ones, known as alcohol-based hand rubs (ABHRs), typically have ethyl alcohol (ethanol), isopropanol, or n-propanol at concentrations between 60 to 95% alcohol.8 The alcohol-free preparations usually contain quaternary ammonium compounds (benzalkonium chloride or benzethonium chloride). However, these have been found to be less effective and have a risk of contributing to antimicrobial resistance (AMR), hence are not recommended by CDC.

The CDC has recommended the use of ABHRs and hand washing to fight the COVID-19 pandemic. This is due to the structural characteristics of coronaviruses, which are enveloped viruses with lipid bilayer and are easily inactivated by alcohol. A combination of factors such as inappropriate formulations, excessive/repeated usage of hand sanitizers during this pandemic will have far reaching consequences. These may range from emergence of situation like alcohol tolerance and antimicrobial resistance (AMR), disturbance of normal microflora, and product toxicity. Similar to antibiotics, excessive or repetitive application of alcohol through hand-sanitizers has the potential to act as a selection pressure for the emergence of new microbial species tolerant to high alcohol concentrations.9

Taking note of the repetitive use of ABHRs, Professor Tim Stinear from the Peter Doherty Institute for Infection and Immunity remarked

Anywhere we repeat a procedure over and over again, whether its in a hospital or at home or anywhere else, youre giving bacteria an opportunity to adapt, because thats what they do, they mutate. The ones that survive the new environment better then go on to thrive.

He further added that the risk increases when appropriate guidelines are not followed.10

Eliminating the normal microflora of the skin by repeated use of hand-sanitizers may eventually deprive the skin of the protection offered by these commensals. Long term use of personal protective equipment along with frequent hand hygiene was responsible for high rate of skin damage in 97% of respondents while frequent hand hygiene was attributed with increased risk of hand skin damage.11

The world has joined hands with parallel efforts for the production of vaccines in opposition to COVID-19 pandemic.

A densely populated area like Ladakh has set an example for implementation in the Guidelines for hygiene and sanitation during the era of COVID-19 pandemic by setting up Foot-Operated Washing Station, implemented at the Indian Astronomical Observatory (IAO), Hanle. Having one of the worlds highest located sites for optical, infrared and gamma-ray telescopes operated by the Indian Institute of Astrophysics (IIA), Bengaluru, IAO12 has one in all the worlds highest set sites for optical, infrared and gamma-ray telescopes.

Antiviral nano-coating and new nano-based material for use in Personal Protective Equipment (PPE) was invited by The Department of Science and Technology (DST) using the Science and Engineering Research Board (SERB) portal, scale up for which could be done by partnering industry or start-up. India could be supported greatly by such nano-coatings technology to fight against COVID-19 pandemic. N-95 respirator, PPEs kits and triple-layer medical masks could be prepared from antiviral nano-coatings for safeguarding healthcare workers.13

Patients that showed flu-like symptoms was screened and detected for COVID-19 through indigenous company Mylab Discovery Solutions through the development of PCR-based molecular diagnostic kit.

TDB will try to boost the production process of kits so that present capacity could increase from 30,000 tests per day to one lakh tests per day. This automation by company could be achieved within the next few months. Considering the national emergency COVID-19 kit will be deployed by ICMR and CDSCO.14

As the demand increased, production of sanitizers have seen a boom amid coronavirus outbreak. Owing to which alcohol-based herbal sanitizer was developed by NBRI under Council of Scientific and Industrial Research (CSIR)-Aroma Mission as per the World Health Organisation (WHO) guidelines. Apart from having 60% of isopropyl alcohol for killing germs it has essential oil from Tulsi as natural antimicrobial agent. It is not only last for 25 minutes but also prevents skin from dehydrating. Herbal sanitizer has been found to be effective against the pathogen (Staphylococcus epidermidis).15

The Council of Scientific and Industrial Research (CSIR) is leaving no stone unturned in the battle against novel coronavirus. Repurposing of existing drugs is one of the strategies deployed by CSIR. The Council is implementing this strategy by evaluating an existing drug (Sepsivac, that available commercially) that is used for treating gram-negative sepsis patients. Both Gram-negative sepsis patients and critically ill COVID-19 patients, exhibit the altered immune response and a massive change in the cytokine profiles. Cytokines are produced in response to an infection and they are essential for host defence against pathogens. There are six types of cytokines, which belong to different families and the mixtures of cytokines, called cytokine profiles. One of the significant contributors to death by COVID-19, has shown the heightened immune response, called a cytokine storm. The immune system starts attacking both infected as well as uninfected cells and unable to discriminate between a friend and a foe, leading to tissue damage which resulting in sepsis. This drug (Sepsivac) modulates the immune system of the body and thereby inhibits the cytokine storm leading to reduced mortality and faster recovery.16

ICMR releases advisory for use of Cartridge-based Nucleic Acid Amplification Test (CBNAAT) using Cepheid Xpert Xpress SARS-CoV-2, effective from 19 April 2020.17

Indias first antibody-based testing kit was developed by NuLife Consultants and Distributors Pvt. Ltd, New Delhi which takes only fifteen minutes to yield accurate results. It is launched in two weeks and regular production has also started it was approved by the Indian Council of Medical Research (ICMR).18 The new finger prick kit will provide adequate access to cost-effective testing.

Home screening test kit for COVID-19 was launched by Bione with easy-to-use kit displays after approval from the requisite medical regulatory authorities.

In a get through development, the Company has devised the screening kit which can provide respite from the impending fear of the contagion. It will foster timely detection of the disease while acting as a preventive tool for others in proximity to the user, by isolating the carrier immediately. The kit is priced between `20003000 depending upon the global supply, to increase its affordability for the masses. Under normal circumstances, the ready-to-use kits can be received within 23 days of placing the order at their platform. To initiate an effective screening tool for mass screening, the organisation is also in talks to provide bulk orders for early detection.19

Against COVID-19 drugs and experimental molecule are being prepared. SARS-CoV-2 is a single stranded RNA enveloped virus. The angiotensin-converting enzyme 2 (ACE2) receptor of the host cell binds to the spike (S) protein of the viral structure. The host type 2 transmembrane serine protease, TMPRSS2 facilitates the S protein.20 Once the virus enters the host, it starts synthesizing RNA through its RNA dependent RNA polymerase enzyme, which is then translated to products. Structural proteins facilitate the assembly and release of viral particles.21,22

During viral life cycle, chemotherapy is available of various potential targets. There are many non-structural protein promising drug targets which resembles with other coronaviruses (SARS-CoV and MERS-CoV) such as 3-chymotrypsin like protease, papain like protease and RNA-dependent RNA polymerase. Various molecules and their targets are represented in Figure 1.

Figure 1 Mechanism of various drugs/molecules on COVID-19 disease.

Chloroquine and hydroxychloroquine used in prevention and treatment of malaria and chronic inflammatory diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA).23 CQ and HCQ are reliable anti-malarial drugs approved by FDA, which shows positive response against SARS-CoV-2 infections and hence used for the treatment of COVID-19 patients by clinicians.2426 It inhibits the entry of the virus by either altering the configuration of structure of cell receptors or by compete to bind with cellular receptors.27 The glycosylation of ACE-2 cellular receptors can amend by CQ/HCQ which is needed for entry of SARS-CoV-2. Apart from that CQ/HCQ can also prevent the attachment of SARS-CoV-2 to the host cells by decrease the synthesis of sialic acid.

The binding affinity of these drugs is better as compared to the S protein of SARS-CoV-2. Therefore it prevents attachment and entry of virus because of competitive binding of sialic acid and gangliosides present on surface pf target cell.28

In addition to the antiviral activity of CQ/HCQ, they have anti-inflammatory activity that may contribute to its efficacy in treating COVID-19 patients. Through the attenuation of cytokine production, these drugs also have immunomodulatory effects and inhibition of lysosomal and autophagy activity in host cells.24,29 In vitro activity of HCQ with lower EC50 for SARS-CoV-2 as compared to CQ after the growth of 24 hours (HCQ: EC50=6.14 M and CQ: EC50=23.90 M).30

A study from China reported which results in improved radiologic findings, enhanced viral clearance, and reduced disease progression by treating successfully with CQ on 100 COVID-19 cases.31 When treatment given to 6 patients, then it is observed that as compared to HCQ monotherapy (8/14, 57%) the combination of azithromycin with HCQ (6/6, 100%) results in numerically superior viral clearance.32

Other than these positive results, this study has many limitations like intolerance of medication, different viral loads between HQC combination and monotherapy and no safety outcomes are reported.

Another study of 30 patients in China shows there was no difference in virologic outcomes to HCQ plus standard of care (supportive care, interferon, and other antivirals). At 7th day virologic clearance was similar with clearance for the HCQ plus standard of care group and standard care group ie 86.7% vs 93.3% respectively, (P>.05).33 Currently, for COVID-19 treatment several RCTs of both CQ and HCQ examining their roles. To treat COVID 19 500 mg dose of CQ orally once or twice daily is advised.8,9

However, there is shortage of data regarding the optical dose to ensure efficiency of CQ For HCQ, daily dose of 400 mg taken orally is recommended.34

Both the agents are well tolerated by patients with SLE and malaria as demonstrated by their experiences and they can cause rare and serious adverse effect (>10%) such as hypoglycemia, neuropsychiatric effects, and retinopathy.

Lopinavir/ritonavir is FDA approved for treating HIV and it shows in vitro activity against coronavirus by inhibiting 3-chymotrypsin like protease.35 The therapy during early peak viral replication phase (initial 710 days) is important because delayed medication with lopinavir/ritonavir had no effective outcomes.36,37

Although many RCTs of lopinavir/ritonavir examine their role, limited role for lopinavir/ritonavir in COVID-19 treatment is suggested through current data.38

Recent RCT shows that approximately 50% of patients experienced an adverse effect under the lopinavir/ritonavir therapy and 14% of patients stop therapy due to adverse effects on gastrointestinal region. In several COVID-19 investigational trials, alanine transaminase elevations are exclusion criterion. Hepatotoxicity induced by lopinavir/ritonavir could limit patients ability to access these drugs.39

The activity of darunavir is demonstrated in vitro cell models against SARS-CoV-2. With these drugs there is no clinical data is available in COVID 19, but in China RCT of darunavir/cobicistat is going on.40,41 Ribavirin is a analogue to guanine which inhibits viral RNA-dependent RNA polymerase and used as best candidate for treatment of COVID 19.

However, it has limited in vitro activity against SARS-CoV and high doses is required to prevent viral replication (e.g., 1.2 g to 2.4 g orally every 8 hours) and combination therapy. For nCoV treatment no evidence exists for inhaled ribavirin..42 Generally ribavirin is used in combination with interferons in the treatment of MERS, no visible effect is shown on clinical outcomes. A lack of clinical data with ribavirin for treatment of COVID 19, means its therapeutic role must be extrapolated from other nCoV data.43,44 The high doses used during trials SARS resulted in hematologic toxicity and hemolytic anemia in more than 60% of patients. Similar safety concerns were seen in MERS trial, with 40% of patients taking ribavirin with interferon requiring blood transfusions. 75% of patients experienced transaminase elevations while taking ribavirin for SARS. Ribavirin is a teratogen and prescribed as not to be used pregnancy.45,46

It is a nucleoside reverse - transcriptase inhibitor that is worthy in clinical trial against COVID-19. It acts as an inhibitor of RNA-dependent RNA polymerase (RdRp)47 and in SARS-CoV and MERS-CoV infections its pharmacokinetics and characteristics have been studied.48 It inhibits the viral genomic replication and production by disturbed reading due to alteration in the function of viral exonuclease.49

Therefore it can suggested for COVID 19 patients to prevent severity of disease progression such patients are taken to phase 3 trials to check the therapeutic efficiency of remdesivir.50

Favipiravir (T705) is considered as RdRp inhibitor as it is an analog to guanine nucleotide (a derivative of pyrazine carboxamide).51 Initially it was used against influenza but because of its large spectrum antiviral properties, it attracted more attention for treatment of COVID 19.52

An in silico study showed that as compared to lopinavir, atazanavir bound more strongly to the active site of SARS-CoV-2 MPro and an in vitro study found that replication of SARS-CoV-2 inhibited by atazanavir.53

Oseltamivir is used for treatment of influenza because it acts as a neuraminidase inhibitor. It has no data against SARS-CoV-2. Initially in China during the COVID-19 outbreak until the discovery of SARS-CoV-2 as the cause of COVID-19 a large proportion of patients were treated with oseltamivir therapy because outbreak occurred in influenza season.

Once influenza has been excluded this agent has no role in the management of COVID-19.54 Umifenovir has a unique mechanism of action targeting the S protein interaction and inhibiting membrane fusion of the viral envelope. This agent is approved for treatment of influenza in Russia and China and treatment of COVID 19 patients started on the basis of in vitro data which shows its activity against SARS.

A study shows that 67 patients treated with Umifenovir for 9 days had a lower mortality rate and higher discharge rate compared with the patients who were not treated with this medication. This data cannot proof the efficiency of umifenovir, but for evaluating this agent further RCTs are going on in China.55.

For SARS-CoV-2 interferon- and - have been studied, due to their demonstrating activity against MERS by interferon-. Some interferons are listed as an alternative for combination therapy by Chinese guidelines. Traditionally other agents are used to demonstrate in vitro activity to inhibit SARS-CoV-2, but not limited to baricitinib, dasatinib, and cyclosporine. However it should be seen whether it provide protection for COVID 19 patients or not.56

Nitazoxanide has in vitro antiviral activity against MERS and SARS-CoV-2. It is used traditionally as an antihelminthic agent. More studies are required to check the antiviral activity and immunomodulatory effects of this agent. For treatment option for SARS-CoV-2 nitazoxanide is recommended.57 In Japan camostat mesylate is used for treatment of pancreatitis, it prevents cell entry through the host serine protease, TMPRSS2. For future research this mechanism provides an additional drug target.58

The ACE2 receptor is used by SARS-CoV-2 for entry into the host cell. This discovery has increased questions about whether ACE inhibitors and/or angiotensin receptor blockers may efficiently treat COVID-19 or either worsen disease. There are some conflicts if these provide protective effect to COVID-19 patients. Further research is pending for recommending therapy for patients already taking one of these agents.59,60

One of the main challenges in this pandemic is to develop multiple technology platforms for evaluation of agents/molecules against SARS-CoV-2 as this virus shows similarity with various other (Figure 1) corona viruses and shares similar binding receptors (ACE2) in humans (host).61 SARS-CoV-2 has ss-RNA genome of approximately 30 Kbp size and exhibits approximately 89% nucleotide similarly to SARS-CoV found in Chinese bats.20

For SARS-CoV 2 various technologies are being developed such as nucleic acid, replicating viral vector and non-replicating viral vector. New methods based on nucleic acid can facilitate rapid production because they do not need to be fermented. Experiments are conducted to ensure vaccination of larger population without any reduction in efficacy but also with improved immune response along with low dosages.62,63

As of January 2021, more than 200 vaccine candidates for COVID-19 are being tested. Among these almost 52 vaccines are approved for human trials and many other vaccines are in phases I/II and will soon enter phase III trials. Certain national regulatory authorities have nine authorized COVID-19 vaccines.

It represents a classic strategy for viral vaccinations. Finally, a codon deoptimization technology to attenuate the viruses is employed by Codagenix64 and is testing to develop vaccine against SARS-CoV-2, CodaVax-COVID. The inherent immunogenicity and ability to stimulate toll-like receptors (TLRs) is a major advantage of whole virus vaccines. This is especially an issue for coronavirus vaccines, given the findings of increased infectivity following immunization with live or killed whole virus SARS coronavirus vaccines.65

Subunit vaccines depend on producing immune response against S protein to inhibit its binding with host ACE2 receptor.65 Immunogenic virus-like nanoparticles produced by Novavax are based on recombinant expression of the S-protein66 while subunit vaccine consisted of a trimerized SARS-CoV-2 S-protein is developed by Clover Biopharmaceuticals by using their patented Trimer-Tag technology.67

For development of COVID-19 vaccines several major biotech industries have advanced nucleic acid vaccine platforms. Some modifications and formulation have improved nucleic acid performance in humans. This approach may lead to the first licensed nucleic acid based vaccine for humans.

Developing vaccine against the SARS-CoV-2 can cause distinct challenges. Various proteins of SARS-CoV-2 are used for developing proteins like S protein, N protein, M protein is the initial challenge. Developing a vaccine is a long process, starting from product development to the completion of phase III and clinical trials before marketing which takes several years.

Vaccine against COVID-19, known as CoroFlu is under process and its development and testing is done by Bharat Biotech in collaboration with international virologists and vaccine makers. One-drop COVID-19 nasal vaccine named CoroFlu, it is well tolerated in human trials during phase I and phase II. On the backbone of FluGens flu vaccine, CoroFlu has built a candidate known as M2SR. M2SR induces an immune response against the flu; it is a self-limiting version of the influenza virus. To induce immunity against the coronavirus in new virus, Kawaokas lab is trying to insert the gene sequences from SARS-CoV-2 into M2SR.68

To develop a vaccine for SARS-CoV-2, Zydus Cadila, an innovation-driven global pharmaceutical company, initiated a research program along with multiple teams. By reverse genetics the recombinant measles virus (rMV) is produced. It would express codon optimised proteins of the SARS-CoV-2 and provide long-term neutralising antibodies for protection from infection. The plasmid DNA vaccine, also has wide ranging capabilities in developing and manufacturing different vaccines for unmet needs. This is under supervision of the groups Vaccine Technology Centre in India.69

To develop a lead vaccine candidate for SARS-CoV-2 the Vaccine manufacturer Indian Immunologicals Ltd (IIL) has a research collaboration agreement with Australias Griffith University. As part of the cross-continental collaboration, using the latest codon de-optimisation technology Live Attenuated SARS-CoV-2 vaccine could be developed by scientists from IIL and the Griffith University. with a single dose administration this vaccine is expected to provide long protection with an anticipated safety profile for active immunization.70

Now the SII (Serum Institute of india) is preparing its mass production against the coronavirus, mixing out doses of the Covishield candidate vaccine which is being developed by the University of Oxford and the international biopharma company AstraZeneca. In India stage III clinical trials of Covishield are continuing. In the US, Brazil and South Africa the candidate vaccine is also being tested in various stages. Two million doses of the vaccine candidate has already produced over for use in testing by the SII. Recently SII announced a deal with Codagenix, US-based Biotech Company to help develop a vaccine candidate and it is expected that its trials starts by the end of 2020. Nasal COVID-19 vaccine candidate developed by Codagenix Inc. Dubbed the DX-005, manufacturing by SII has started.

After completing preclinical animal studies the coronavirus vaccine entered phase I clinical trials in the United Kingdom by the end of 2020. Bharat Biotech, a private firm collaborated with Indian Council of Medical Research (ICMR) is developing Covaxin. Covaxin has shown good efficacy is said by task force scientist Dr. Rajni Kant ICMR-COVID-19. Bharat Biotech is approved by The Drugs Controller General of India (DCGI) to perform Phase III clinical trials of Covaxin with certain conditions.

Russias president Vladimir Putin endorsed approval of SPUTNIK V (COVID-19 vaccine) that has not passed rigorous medical tests and could have numerous consequences. The effectiveness of the vaccine in response to providing active acquired immunity against COVID-19 and its possible adverse effects remain unknown. Therefore, the fear of vaccination in this particular case may be justified. However, endorsement of a potentially harmful vaccine will inevitably fuel public fears of other existing and future, properly developed, controlled and safe vaccines. Current level of public acceptability of immunization is already worrying, putting at serious risk the effectiveness of any future anti-SARS-CoV-2 vaccination programs, as it has been pointed out by Cornwall 2 and the French COCONEL Group 3. Independently from each other these groups provide evidence that it is a transatlantic phenomenon. Regardless of the suggested correlations between vaccination hesitancy and specific socioeconomic factors, it is clear that anti-vaccination movements are increasingly influential.71 Moreover, the problem is internationally valid, and the rise in the number of adults openly hesitant about routine childhood vaccination in many Western countries justifies the concern about public participation once the COVID-19 vaccine is available.72

In terms of collective immunity, vaccination effectiveness is based on its mass implementation; this may seriously undermine the efforts to protect societies against COVID-19 in the near future. High levels of COVID-19 vaccine hesitancy are reported even from countries severely affected by the pandemic. Only 49% of American respondents plan to vaccinate when the vaccine becomes available.73

Polish research confirms the strong COVID-19 vaccination hesitancy and its international character which is not directly related to the level of confidence in vaccination safety in general. Results of this Polish study show that 28% of adults would not vaccinate against SARS-CoV-2 if the vaccine became available. Alarmingly, a majority (51%) of the reluctant respondents indicated that their minds would not be changed if given information regarding vaccine safety or efficacy, or if threatened with heavy fines. Significantly fewer respondents (37%) supported COVID-19 vaccinations specifically than supported childhood vaccinations in Poland in general (78% in 2018).74 The vaccine hesitancy for the anticipated COVID-19 vaccine varied from very low (26% China) to very high (43%, Czechia, and 44%, Turkey). Surprisingly, the level of unwillingness to vaccinate against COVID-19 is in most countries much higher than regular vaccination reluctance, which varies between 3% (Egypt) and 55% (Russia). Such high levels of vaccination hesitancy may be detrimental to public health. According to current estimates, the benefits of herd immunity are achievable if 67% of the population is vaccinated.75,76

The most effective vaccination programs in the past effectively eradicated certain deadly diseases, such as smallpox which was achieved by combining the mandatory preventive vaccination programs with coordinated education efforts.77 Coronaviruses mortality rate is the highest among elders and people with comorbidities or conditions that affect their immune system. Some occupations have been identified as being the riskiest in terms of contracting COVID-19 such as health-care workers (dental hygienists, family practitioners, and nurses), transportation personnel (flying attendants, and school bus drivers), kindergarten, school teachers, fire fighters and restaurant personnel.78 Highest risk of death and highest risk of contraction should constitute the main criteria for mandatory vaccination. Mandatory vaccination will definitely trigger massive opposition especially bearing in mind the massive protests against social distancing measures and face masks. Focusing at the beginning only on some groups with transparent justification may help weaken the opposition to it.79

The high share of the population unwilling to vaccinate along with the number of people who are unable to receive the COVID-19 vaccine due to certain medical reasons suggests herd immunity may be out of reach. Information about the high death tolls and hospital overflows from the COVID-19 pandemic has recently flooded onto online media, but has apparently not convinced much of the worlds population to plan to be vaccinated. If the disturbing images being streamed live on social media cannot convince a fair share of the population to protect themselves from lethal risk, then educational or social campaigns may be limited in their effect. Educational efforts would be further undermined by the lack of trust in public authority figures, which fuels conspiracy theories and validates medical fake news. In this focused review we have discussed the challenges and opportunities faced during the management of COVID-19 in India.

Health-care systems across developed and developing nations are under tremendous pressure. The majority of this responsibility is being shouldered by frontline health-care workers to limit the spread of the novel coronavirus. They put their lives on the line in order to do so. Here we highlight some challenges faced by frontline HCW and propose certain recommendations to reduce the burden.

The exposure to the virus causes severe illness and mortality to a significant extent and also leads to physical and psychological exhaustion. This pandemic leads to health departments calling retired and experienced medical staff and clinical scientist back to work. Deficient supplies of personal protective equipment (PPEs) and other vital necessities is reported in various news channels all over the world. Majorly WHCs are affected and they are working in the emergency, they need PPEs and other vital necessities most.

In this pandemic, battling endless hours, staff shortages and deficient supplies, most are isolated from their families, affecting them physically, mentally, and emotionally, which will increase the morbidity and ill health.80 These mental health problems will not only affect decision making ability, judgement and attention of HCWs, but also affect the understanding the disease and have a long-lasting impact on their overall well-being.80

A few recommendations are proposed which are listed from all the information received around this issue.

Health-care staff/HCWs are also the most important resource as hospitals, equipments and PPEs in this pandemic situation. Post Traumatic Stress Disorder is reported in many health-care workers who have no time to protect themselves as well as their families. If any staff gets infected then they should be quarantined themselves, which leads to a shortage of staff and then healthy workers are stretched further for endless duties with lack of sleep and anxiety. For frontline health workers testing kits must be prioritized, as well as for weak communities (senior citizens) more susceptible to the virus and those who have many pre-existing diseases.81,82

Health-care workers face a high risk of getting infected as they take care of patients who are already infected. Protective clothing, sufficient hand sanitizers, washing paraphernalia and head covers are essential commodities which have to be provided to them in sufficient amount. Along with providing PPEs in adequate amount, its disposal methodology is also an important step across all the clinical areas since it can be one of the reasons of spreading infection.31

These are key phrases which provide the adequate time for the systems to gather resources and capacity to help in breaking the chain of transmission. The virus infects exponentially which is very clear and many will contract it very soon. State should provide premises to serve as isolation ward and quarantine spaces. All hospitals should use their full area to create control committees to monitor activities to ensure protocols are implemented for effective control. The loop has to be complete, involving community systems, governments and primary health-care workers are key, since not everyone will report to hospitals, if community transmission will be rampant.

The comfort and willingness in working for a health system which has an effective plan, magnifies many times in a pandemic. Protocols in local languages for better understanding and awareness material based on science research have been useful. Offering free transport service between work and home, childcare support and meal vouchers can reduce domestic stress and allow single-minded effort towards the health service.83

Apart from the various negative effect imposed by the pandemic, positive vibes of it cannot be neglected. The pandemic situation significantly improves air quality in different cities across the country, reduces GHGs emission, lessens water pollution and noise, and reduces the pressure on the tourist destinations, which may assist with the restoration of the ecological systems.84 These changes may be short term but are important for maintenance of environmental balance. Apart from this, various successful models like that of Dharavi and Kerala model were implemented which restricted the cases to a minimum through observing the spread in the localities, studying the prototype of spread, and strict use of methods to control the disease in Kerala. Dharavi restricted the coronavirus cases with a strategy of attack not defence and elucidated triumphant results in 2 months.85

There are more than 56 COVID-19 candidate vaccines in clinical evaluation of which 13 are in phase III trials and another 166 candidate vaccines are in preclinical evaluation (Table 1). All top candidate vaccines will be delivered through intra-muscular injection and are designed for a two-dose schedule.86 More recently our group has suggested the combinatorial use of childhood vaccines (BCG, MMR and OPV) along with the COVID-19 dedicated vaccines could be a potential strategy to control the COVID-19 pandemic worldwide.87

Table 1 Prospective Therapeutic Representative Against COVID-19 Disease

Strain B.1.1.7 was first detected in the United States in December 2020 followed by B.1.351, in South Africa P.1, in Brazil and Japan, B.1.427 and B.1.429. These two variants were first identified in California in February 2021. COVID-19 variant from India is B.1.617; one of the lineages is B.1.617.2, which has been detected most frequently in the US and the U.K.88 Recently the black fungus is now maiming COVID-19 patients in India. Mucormycosis is an invasive infection caused by a class of molds called mucormycetes. It has an overall mortality rate of 50%, and may be being triggered by the use of unhygienic oxygen cylinders and steroids, a life-saving treatment for severe and critically ill COVID-19 patients.89

In this review, we have been discussed the stories related to prevention strategies, chemotherapeutics and vaccines strategies to manage COVID-19. Apart from that we have discussed the challenges faced by HCWs and their prevention. Combating COVID-19 is still a challenge also due to the poorly-based counsel for using an experimental amalgamation of antimalarials and antimicrobials as treatment; the use of steroids; and antihypertensive drugs during the course of the disease. Interruption of the transmission of SARS-CoV-2 through engineered vaccines is top in the priority followed by the intense research to find out the potential treatment to control this viral infection.

Alternative medicine – Wikipedia

Alternative or fringe medicine is any practice claimed to have the healing effects of medicine and is: proven not to work; has no scientific evidence showing that it works; or that is solely harmful.[n 1][n 2][n 3] Alternative medicine is not a part of medicine,[n 1][n 4][n 5][n 6] or science-based healthcare systems.[1][2][4] It consists of a wide variety of practices, products, and therapiesranging from those that are biologically plausible but not well tested, to those with known harmful and toxic effects.[n 4][5][6][7][8][9] Despite significant costs in testing alternative medicine, including $2.5 billion spent by the United States government, almost none have shown any effectiveness beyond that of false treatments (placebo).[10][11] Perceived effects of alternative medicine are caused by the placebo effect, decreased effects of functional treatment (and thus also decreased side-effects),[12] and regression toward the mean where spontaneous improvement is credited to alternative therapies.

Complementary medicine or integrative medicine is when alternative medicine is used together with functional medical treatment, in a belief that it "complements" (improves the efficacy of) the treatment.[n 7][14][15][16][17] However, significant drug interactions caused by alternative therapies may instead negatively influence the treatment, making treatments less effective, notably cancer therapy.[12][18]

CAM is an abbreviation of complementary and alternative medicine.[19][20] It has also be called sCAM or SCAM for "so-called complementary and alternative medicine" or "supplements and complementary and alternative medicine".[21][22] The word Holistic is often use, claiming to take into account the "whole" person, in contrast to the supposed reductionism of medicine. Due to its many names the field has been criticized for intense rebranding of what are essentially the same practices: as soon as one name is declared synonymous with quackery, a new is chosen.[23]

Alternative medical diagnoses and treatments are not included in the science-based treatments taught in medical schools, and are not used in medical practice where treatments are based on scientific knowledge. Alternative therapies are either unproven, disproved, or impossible to prove,[n 8][5][14][25][26] and are often based on religion, tradition, superstition, belief in supernatural energies, pseudoscience, errors in reasoning, propaganda, or fraud.[5][6][14][27] Regulation and licensing of alternative medicine and health care providers varies between and within countries. Marketing alternative therapies as treating or preventing cancer is illegal in many countries including the United States and most parts of the European Union.

Alternative medicine has been criticized for being based on misleading statements, quackery, pseudoscience, antiscience, fraud, or poor scientific methodology. Promoting alternative medicine has been called dangerous and unethical.[n 9][29] Testing alternative medicine that have no scientific basis has been called a waste of scarce medical research resources.[30][31] Critics have said "there is really no such thing as alternative medicine, just medicine that works and medicine that doesn't",[32] and the problem is not only that it does not work, but that the "underlying logic is magical, childish or downright absurd".[33] There have also been calls that the concept of any alternative medicine that works is paradoxical, as any treatment proven to work is simply "medicine".[34]

It is loosely as a defined set of products, practices, and theories that are believed or perceived by their users to have the healing effects of medicine,[n 2][n 4] but whose effectiveness has not been clearly established using scientific methods,[n 2][n 3][5][6][24][26]and whose theory and practice is not part of biomedicine,[n 4][n 1][n 5][n 6] or whose theories or practices are directly contradicted by scientific evidence or scientific principles used in biomedicine.[5][6][27] "Biomedicine" or "medicine" is that part of medical science that applies principles of biology, physiology, molecular biology, biophysics, and other natural sciences to clinical practice, using scientific methods to establish the effectiveness of that practice. Unlike medicine,[n 1] an alternative product or practice does not originate from using scientific methodology, but may instead be based on testimonials, religion, tradition, superstition, belief in supernatural energies, pseudoscience, errors in reasoning, propaganda, fraud, or other unscientific sources.[n 3][5][6][14]

The expression also refers to a diverse range of related and unrelated products, practices, and theories ranging from biologically plausible practices and products and practices with some evidence, to practices and theories that are directly contradicted by basic science or clear evidence, and products that have been conclusively proven to be ineffective or even toxic and harmful.[n 4][7][8]

The terms-Alternative medicine, complementary medicine, integrative medicine, holistic medicine, natural medicine, unorthodox medicine, fringe medicine, unconventional medicine, and new age medicine are used interchangeably as having the same meaning and are almost synonymous in some contexts,[23][39][40][41] but may have different meanings in some rare cases.

The meaning of the term "alternative" in the expression "alternative medicine", is not that it is an effective alternative to medical science, although some alternative medicine promoters may use the loose terminology to give the appearance of effectiveness.[5][42] Loose terminology may also be used to suggest meaning that a dichotomy exists when it does not, e.g., the use of the expressions "western medicine" and "eastern medicine" to suggest that the difference is a cultural difference between the Asiatic east and the European west, rather than that the difference is between evidence-based medicine and treatments that don't work.[5]

It refers to use of alternative medical treatments alongside conventional medicine, in the belief that it increases the effectiveness of the conventional medicine.[43][44][45] An example of "complementary medicine" is use of acupuncture (sticking needles in the body to influence the flow of a supernatural energy), along with using science-based medicine, in the belief that the acupuncture increases the effectiveness or "complements" the science-based medicine.[45]

It refers to the pre-scientific practices of a culture, contrary to what is traditionally practiced in cultures where medical science dominates.

"Eastern medicine" typically refers to the traditional medicines of Asia where conventional bio-medicine penetrated much later.

Prominent members of the science[32][46] and biomedical science community[25] assert that it is not meaningful to define an alternative medicine that is separate from a conventional medicine, that the expressions "conventional medicine", "alternative medicine", "complementary medicine", "integrative medicine", and "holistic medicine" do not refer to any medicine at all.[25][32][46][47]

Others in both the biomedical and CAM communities point out that CAM cannot be precisely defined because of the diversity of theories and practices it includes, and because the boundaries between CAM and biomedicine overlap, are porous, and change. The expression "complementary and alternative medicine" (CAM) resists easy definition because the health systems and practices it refers to are diffuse, and its boundaries poorly defined.[7][n 10] Healthcare practices categorized as alternative may differ in their historical origin, theoretical basis, diagnostic technique, therapeutic practice and in their relationship to the medical mainstream. Some alternative therapies, including traditional Chinese medicine (TCM) and Ayurveda, have antique origins in East or South Asia and are entirely alternative medical systems;[52] others, such as homeopathy and chiropractic, have origins in Europe or the United States and emerged in the eighteenth and nineteenth centuries. Some, such as osteopathy and chiropractic, employ manipulative physical methods of treatment; others, such as meditation and prayer, are based on mind-body interventions. Treatments considered alternative in one location may be considered conventional in another.[55] Thus, chiropractic is not considered alternative in Denmark and likewise osteopathic medicine is no longer thought of as an alternative therapy in the United States.[55]

One common feature of all definitions of alternative medicine is its designation as "other than" conventional medicine. For example, the widely referenced descriptive definition of complementary and alternative medicine devised by the US National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health (NIH), states that it is "a group of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine."[1] For conventional medical practitioners, it does not necessarily follow that either it or its practitioners would no longer be considered alternative.[n 11]

Some definitions seek to specify alternative medicine in terms of its social and political marginality to mainstream healthcare.[60] This can refer to the lack of support that alternative therapies receive from the medical establishment and related bodies regarding access to research funding, sympathetic coverage in the medical press, or inclusion in the standard medical curriculum.[60] In 1993, the British Medical Association (BMA), one among many professional organizations who have attempted to define alternative medicine, stated that it[n 12] referred to "...those forms of treatment which are not widely used by the conventional healthcare professions, and the skills of which are not taught as part of the undergraduate curriculum of conventional medical and paramedical healthcare courses."[61] In a US context, an influential definition coined in 1993 by the Harvard-based physician,[62] David M. Eisenberg,[63] characterized alternative medicine "as interventions neither taught widely in medical schools nor generally available in US hospitals".[64] These descriptive definitions are inadequate in the present-day when some conventional doctors offer alternative medical treatments and CAM introductory courses or modules can be offered as part of standard undergraduate medical training;[65] alternative medicine is taught in more than 50 per cent of US medical schools and increasingly US health insurers are willing to provide reimbursement for CAM therapies. In 1999, 7.7% of US hospitals reported using some form of CAM therapy; this proportion had risen to 37.7% by 2008.[67]

An expert panel at a conference hosted in 1995 by the US Office for Alternative Medicine (OAM),[68][n 13] devised a theoretical definition[68] of alternative medicine as "a broad domain of healing resources... other than those intrinsic to the politically dominant health system of a particular society or culture in a given historical period."[69] This definition has been widely adopted by CAM researchers,[68] cited by official government bodies such as the UK Department of Health,[70] attributed as the definition used by the Cochrane Collaboration,[71] and, with some modification,[dubious discuss] was preferred in the 2005 consensus report of the US Institute of Medicine, Complementary and Alternative Medicine in the United States.[n 4]

The 1995 OAM conference definition, an expansion of Eisenberg's 1993 formulation, is silent regarding questions of the medical effectiveness of alternative therapies.[72] Its proponents hold that it thus avoids relativism about differing forms of medical knowledge and, while it is an essentially political definition, this should not imply that the dominance of mainstream biomedicine is solely due to political forces.[72] According to this definition, alternative and mainstream medicine can only be differentiated with reference to what is "intrinsic to the politically dominant health system of a particular society of culture".[73] However, there is neither a reliable method to distinguish between cultures and subcultures, nor to attribute them as dominant or subordinate, nor any accepted criteria to determine the dominance of a cultural entity.[73] If the culture of a politically dominant healthcare system is held to be equivalent to the perspectives of those charged with the medical management of leading healthcare institutions and programs, the definition fails to recognize the potential for division either within such an elite or between a healthcare elite and the wider population.[73]

Normative definitions distinguish alternative medicine from the biomedical mainstream in its provision of therapies that are unproven, unvalidated, or ineffective and support of theories with no recognized scientific basis. These definitions characterize practices as constituting alternative medicine when, used independently or in place of evidence-based medicine, they are put forward as having the healing effects of medicine, but are not based on evidence gathered with the scientific method.[1][14][25][43][44][75] Exemplifying this perspective, a 1998 editorial co-authored by Marcia Angell, a former editor of the New England Journal of Medicine, argued that:

This line of division has been subject to criticism, however, as not all forms of standard medical practice have adequately demonstrated evidence of benefit, [n 1][76] and it is also unlikely in most instances that conventional therapies, if proven to be ineffective, would ever be classified as CAM.[68]

Public information websites maintained by the governments of the US and of the UK make a distinction between "alternative medicine" and "complementary medicine", but mention that these two overlap. The National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health (NIH) (a part of the US Department of Health and Human Services) states that "alternative medicine" refers to using a non-mainstream approach in place of conventional medicine and that "complementary medicine" generally refers to using a non-mainstream approach together with conventional medicine, and comments that the boundaries between complementary and conventional medicine overlap and change with time.[1]

The National Health Service (NHS) website NHS Choices (owned by the UK Department of Health), adopting the terminology of NCCIH, states that when a treatment is used alongside conventional treatments, to help a patient cope with a health condition, and not as an alternative to conventional treatment, this use of treatments can be called "complementary medicine"; but when a treatment is used instead of conventional medicine, with the intention of treating or curing a health condition, the use can be called "alternative medicine".[78]

Similarly, the public information website maintained by the National Health and Medical Research Council (NHMRC) of the Commonwealth of Australia uses the acronym "CAM" for a wide range of health care practices, therapies, procedures and devices not within the domain of conventional medicine. In the Australian context this is stated to include acupuncture; aromatherapy; chiropractic; homeopathy; massage; meditation and relaxation therapies; naturopathy; osteopathy; reflexology, traditional Chinese medicine; and the use of vitamin supplements.[79]

The Danish National Board of Health's "Council for Alternative Medicine" (Sundhedsstyrelsens Rd for Alternativ Behandling (SRAB)), an independent institution under the National Board of Health (Danish: Sundhedsstyrelsen), uses the term "alternative medicine" for:

In General Guidelines for Methodologies on Research and Evaluation of Traditional Medicine, published in 2000 by the World Health Organization (WHO), complementary and alternative medicine were defined as a broad set of health care practices that are not part of that country's own tradition and are not integrated into the dominant health care system.[81] Some herbal therapies are mainstream in Europe but are alternative in the US.[83]

A United States government agency, the National Center on Complementary and Integrative Health (NCCIH), created its own classification system for branches of complementary and alternative medicine that divides them into five major groups. These groups have some overlap, and distinguish two types of energy medicine: veritable which involves scientifically observable energy (including magnet therapy, colorpuncture and light therapy) and putative, which invokes physically undetectable or unverifiable energy.[84]

Alternative medicine practices and beliefs are diverse in their foundations and methodologies. The wide range of treatments and practices referred to as alternative medicine includes some stemming from nineteenth century North America, such as chiropractic and naturopathy, others, mentioned by Jtte, that originated in eighteenth- and nineteenth-century Germany, such as homeopathy and hydropathy,[85] and some that have originated in China or India, while African, Caribbean, Pacific Island, Native American, and other regional cultures have traditional medical systems as diverse as their diversity of cultures.[1]

Examples of CAM as a broader term for unorthodox treatment and diagnosis of illnesses, disease, infections, etc.,[86] include yoga, acupuncture, aromatherapy, chiropractic, herbalism, homeopathy, hypnotherapy, massage, osteopathy, reflexology, relaxation therapies, spiritual healing and tai chi.[86] CAM differs from conventional medicine. It is normally private medicine and not covered by health insurance.[86] It is paid out of pocket by the patient and is an expensive treatment.[86] CAM tends to be a treatment for upper class or more educated people.[87]

The NCCIH classification system is -

Alternative medicine consists of a wide range of health care practices, products, and therapies. The shared feature is a claim to heal that is not based on the scientific method. Alternative medicine practices are diverse in their foundations and methodologies.[1] Alternative medicine practices may be classified by their cultural origins or by the types of beliefs upon which they are based.[1][5][14][27] Methods may incorporate or be based on traditional medicinal practices of a particular culture, folk knowledge, supersition, spiritual beliefs, belief in supernatural energies (antiscience), pseudoscience, errors in reasoning, propaganda, fraud, new or different concepts of health and disease, and any bases other than being proven by scientific methods.[5][6][14][27] Different cultures may have their own unique traditional or belief based practices developed recently or over thousands of years, and specific practices or entire systems of practices.

Alternative medicine, such as using naturopathy or homeopathy in place of conventional medicine, is based on belief systems not grounded in science.[1]

Alternative medical systems may be based on traditional medicine practices, such as traditional Chinese medicine (TCM), Ayurveda in India, or practices of other cultures around the world.[1] Some useful applications of traditional medicines have been researched and accepted within ordinary medicine, however the underlying belief systems are seldom scientific and are not accepted.

Bases of belief may include belief in existence of supernatural energies undetected by the science of physics, as in biofields, or in belief in properties of the energies of physics that are inconsistent with the laws of physics, as in energy medicine.[1]

Acupuncture is a component of traditional Chinese medicine. Proponents of acupuncture believe that a supernatural energy called qi flows through the universe and through the body, and helps propel the bloodand that blockage of this energy leads to disease.[99] They believe that inserting needles in various parts of the body, determined by astrological calculations, can restore balance to the blocked flows and thereby cure disease.[99]

In the western version of Japanese Reiki, practitioners place their palms on the patient near Chakras that they believe are centers of supernatural energies, and believe that these supernatural energies can transfer from the practitioner's palms to heal the patient.

Mind-body medicine claims to take a "holistic" (whole) approach to health that explores the interconnection between the mind, body, and spirit. It works under the premise that the mind can affect "bodily functions and symptoms".[1] Mind body medicines includes healing claims made in yoga, meditation, deep-breathing exercises, guided imagery, hypnotherapy, progressive relaxation, qi gong, and tai chi.[1] Notably it does not consider psychology or psychiatry.

Substance based practices use substances found in nature such as herbs, foods, non-vitamin supplements and megavitamins, animal and fungal products, and minerals, including use of these products in traditional medical practices that may also incorporate other methods.[1][11][109] Examples include healing claims for nonvitamin supplements, fish oil, Omega-3 fatty acid, glucosamine, echinacea, flaxseed oil, and ginseng.[110]Herbal medicine, or phytotherapy, includes not just the use of plant products, but may also include the use of animal and mineral products.[11] It is among the most commercially successful branches of alternative medicine, and includes the tablets, powders and elixirs that are sold as "nutritional supplements".[11] Only a very small percentage of these have been shown to have any efficacy, and there is little regulation as to standards and safety of their contents.[11] This may include use of known toxic substances, such as use of the poison lead in traditional Chinese medicine.[110]

Manipulative and body-based practices feature the manipulation or movement of body parts, such as is done in bodywork and chiropractic manipulation.

Osteopathic manipulative medicine, also known as osteopathic manipulative treatment, is a core set of techniques of osteopathy and osteopathic medicine distinguishing these fields from mainstream medicine.[111]

Religion based healing practices, such as use of prayer and the laying of hands in Christian faith healing, and shamanism, rely on belief in divine or spiritual intervention for healing.

Shamanism is a practice of many cultures around the world, in which a practitioner reaches an altered states of consciousness in order to encounter and interact with the spirit world or channel supernatural energies in the belief they can heal.[112]

The history of alternative medicine may refer to the history of a group of diverse medical practices that were collectively promoted as "alternative medicine" beginning in the 1970s, to the collection of individual histories of members of that group, or to the history of western medical practices that were labeled "irregular practices" by the western medical establishment.[5][113][114][115][116] It includes the histories of complementary medicine and of integrative medicine. Before the 1970s, western practitioners that were not part of the increasingly science-based medical establishment were referred to "irregular practitioners", and were dismissed by the medical establishment as unscientific and as practicing quackery.[113][114] Until the 1970's, irregular practice became increasingly marginalized as quackery and fraud, as western medicine increasingly incorporated scientific methods and discoveries, and had a corresponding increase in success of its treatments.[115] In the 1970s, irregular practices were grouped with traditional practices of nonwestern cultures and with other unproven or disproven practices that were not part of biomedicine, with the entire group collectively marketed and promoted under the single expression "alternative medicine".[5][113][114][115][117]

Use of alternative medicine in the west began to rise following the counterculture movement of the 1960s, as part of the rising new age movement of the 1970s.[5][118][119] This was due to misleading mass marketing of "alternative medicine" being an effective "alternative" to biomedicine, changing social attitudes about not using chemicals and challenging the establishment and authority of any kind, sensitivity to giving equal measure to beliefs and practices of other cultures (cultural relativism), and growing frustration and desperation by patients about limitations and side effects of science-based medicine.[5][114][115][116][117][119][120] At the same time, in 1975, the American Medical Association, which played the central role in fighting quackery in the United States, abolished its quackery committee and closed down its Department of Investigation.[113]:xxi[120] By the early to mid 1970s the expression "alternative medicine" came into widespread use, and the expression became mass marketed as a collection of "natural" and effective treatment "alternatives" to science-based biomedicine.[5][120][121][122] By 1983, mass marketing of "alternative medicine" was so pervasive that the British Medical Journal (BMJ) pointed to "an apparently endless stream of books, articles, and radio and television programmes urge on the public the virtues of (alternative medicine) treatments ranging from meditation to drilling a hole in the skull to let in more oxygen".[120] In this 1983 article, the BMJ wrote, "one of the few growth industries in contemporary Britain is alternative medicine", noting that by 1983, "33% of patients with rheumatoid arthritis and 39% of those with backache admitted to having consulted an alternative practitioner".[120]

By about 1990, the American alternative medicine industry had grown to a $27 Billion per year, with polls showing 30% of Americans were using it.[119][123] Moreover, polls showed that Americans made more visits for alternative therapies than the total number of visits to primary care doctors, and American out-of-pocket spending (non-insurance spending) on alternative medicine was about equal to spending on biomedical doctors.[113]:172 In 1991, Time magazine ran a cover story, "The New Age of Alternative Medicine: Why New Age Medicine Is Catching On".[119][123] In 1993, the New England Journal of Medicine reported one in three Americans as using alternative medicine.[119] In 1993, the Public Broadcasting System ran a Bill Moyers special, Healing and the Mind, with Moyers commenting that "...people by the tens of millions are using alternative medicine. If established medicine does not understand that, they are going to lose their clients."[119]

Another explosive growth began in the 1990s, when senior level political figures began promoting alternative medicine, investing large sums of government medical research funds into testing alternative medicine, including testing of scientifically implausible treatments, and relaxing government regulation of alternative medicine products as compared to biomedical products.[5][113]:xxi[114][115][116][117][124][125] Beginning with a 1991 appropriation of $2 million for funding research of alternative medicine research, federal spending grew to a cumulative total of about $2.5 billion by 2009, with 50% of Americans using alternative medicine by 2013.[10][126]

In 1991, pointing to a need for testing because of the widespread use of alternative medicine without authoritative information on its efficacy, United States Senator Tom Harkin used $2 million of his discretionary funds to create the Office for the Study of Unconventional Medical Practices (OSUMP), later renamed to be the Office of Alternative Medicine (OAM).[113]:170[127][128] The OAM was created to be within the National Institute of Health (NIH), the scientifically prestigious primary agency of the United States government responsible for biomedical and health-related research.[113]:170[127][128] The mandate was to investigate, evaluate, and validate effective alternative medicine treatments, and alert the public as the results of testing its efficacy.[123][127][128][129]

Sen. Harkin had become convinced his allergies were cured by taking bee pollen pills, and was urged to make the spending by two of his influential constituents.[123][127][128] Bedell, a longtime friend of Sen. Harkin, was a former member of the United States House of Representatives who believed that alternative medicine had twice cured him of diseases after mainstream medicine had failed, claiming that cow's milk colostrum cured his Lyme disease, and an herbal derivative from camphor had prevented post surgical recurrence of his prostate cancer.[113][123] Wiewel was a promoter of unproven cancer treatments involving a mixture of blood sera that the Food and Drug Administration had banned from being imported.[123] Both Bedell and Wiewel became members of the advisory panel for the OAM. The company that sold the bee pollen was later fined by the Federal Trade Commission for making false health claims about their bee-pollen products reversing the aging process, curing allergies, and helping with weight loss.[130]

In 1993, Britain's Prince Charles, who claimed that homeopathy and other alternative medicine was an effective alternative to biomedicine, established the Foundation for Integrated Health (FIH), as a charity to explore "how safe, proven complementary therapies can work in conjunction with mainstream medicine".[131] The FIH received government funding through grants from Britain's Department of Health.[131]

In 1994, Sen. Harkin (D) and Senator Orrin Hatch (R) introduced the Dietary Supplement Health and Education Act (DSHEA).[132][133] The act reduced authority of the FDA to monitor products sold as "natural" treatments.[132] Labeling standards were reduced to allow health claims for supplements based only on unconfirmed preliminary studies that were not subjected to scientific peer review, and the act made it more difficult for the FDA to promptly seize products or demand proof of safety where there was evidence of a product being dangerous.[133] The Act became known as the "The 1993 Snake Oil Protection Act" following a New York Times editorial under that name.[132]

Senator Harkin complained about the "unbendable rules of randomized clinical trials", citing his use of bee pollen to treat his allergies, which he claimed to be effective even though it was biologically implausible and efficacy was not established using scientific methods.[127][134] Sen. Harkin asserted that claims for alternative medicine efficacy be allowed not only without conventional scientific testing, even when they are biologically implausible, "It is not necessary for the scientific community to understand the process before the American public can benefit from these therapies."[132] Following passage of the act, sales rose from about $4 billion in 1994, to $20 billion by the end of 2000, at the same time as evidence of their lack of efficacy or harmful effects grew.[132] Senator Harkin came into open public conflict with the first OAM Director Joseph M. Jacobs and OAM board members from the scientific and biomedical community.[128] Jacobs' insistence on rigorous scientific methodology caused friction with Senator Harkin.[127][134][135] Increasing political resistance to the use of scientific methodology was publicly criticized by Dr. Jacobs and another OAM board member complained that "nonsense has trickled down to every aspect of this office".[127][134] In 1994, Senator Harkin appeared on television with cancer patients who blamed Dr. Jacobs for blocking their access to untested cancer treatment, leading Jacobs to resign in frustration.[127][134]

In 1995, Wayne Jonas, a promoter of homeopathy and political ally of Senator Harkin, became the director of the OAM, and continued in that role until 1999.[136] In 1997, the NCCAM budget was increased from $12 million to $20 million annually.[137] From 1990 to 1997, use of alternative medicine in the US increased by 25%, with a corresponding 50% increase in expenditures.[87] The OAM drew increasing criticism from eminent members of the scientific community with letters to the Senate Appropriations Committee when discussion of renewal of funding OAM came up.[113]:175 Nobel laureate Paul Berg wrote that prestigious NIH should not be degraded to act as a cover for quackery, calling the OAM "an embarrassment to serious scientists."[113]:175[137] The president of the American Physical Society wrote complaining that the government was spending money on testing products and practices that "violate basic laws of physics and more clearly resemble witchcraft".[113]:175[137] In 1998, the President of the North Carolina Medical Association publicly called for shutting down the OAM.[138]

In 1998, NIH director and Nobel laureate Harold Varmus came into conflict with Senator Harkin by pushing to have more NIH control of alternative medicine research.[139] The NIH Director placed the OAM under more strict scientific NIH control.[137][139] Senator Harkin responded by elevating OAM into an independent NIH "center", just short of being its own "institute", and renamed to be the National Center for Complementary and Alternative Medicine (NCCAM). NCCAM had a mandate to promote a more rigorous and scientific approach to the study of alternative medicine, research training and career development, outreach, and "integration". In 1999, the NCCAM budget was increased from $20 million to $50 million.[138][139] The United States Congress approved the appropriations without dissent. In 2000, the budget was increased to about $68 million, in 2001 to $90 million, in 2002 to $104 million, and in 2003, to $113 million.[138]

In 2004, modifications of the European Parliament's 2001 Directive 2001/83/EC, regulating all medicine products, were made with the expectation of influencing development of the European market for alternative medicine products.[140] Regulation of alternative medicine in Europe was loosened with "a simplified registration procedure" for traditional herbal medicinal products.[140][141] Plausible "efficacy" for traditional medicine was redefined to be based on long term popularity and testimonials ("the pharmacological effects or efficacy of the medicinal product are plausible on the basis of long-standing use and experience."), without scientific testing.[140][141] The Committee on Herbal Medicinal Products (HMPC) was created within the European Medicines Agency in London (EMEA). A special working group was established for homeopathic remedies under the Heads of Medicines Agencies.[140]

Through 2004, alternative medicine that was traditional to Germany continued to be a regular part of the health care system, including homeopathy and anthroposophic medicine.[140] The German Medicines Act mandated that science-based medical authorities consider the "particular characteristics" of complementary and alternative medicines.[140] By 2004, homeopathy had grown to be the most used alternative therapy in France, growing from 16% of the population using homeopathic medicine in 1982, to 29% by 1987, 36% percent by 1992, and 62% of French mothers using homeopathic medicines by 2004, with 94.5% of French pharmacists advising pregnant women to use homeopathic remedies.[142] As of 2004[update], 100 million people in India depended solely on traditional German homeopathic remedies for their medical care.[143] As of 2010[update], homeopathic remedies continued to be the leading alternative treatment used by European physicians.[142] By 2005, sales of homeopathic remedies and anthroposophical medicine had grown to $930 million Euros, a 60% increase from 1995.[142][144]

In 2008, London's The Times published a letter from Edzard Ernst that asked the FIH to recall two guides promoting alternative medicine, saying: "the majority of alternative therapies appear to be clinically ineffective, and many are downright dangerous." In 2010, Brittan's FIH closed after allegations of fraud and money laundering led to arrests of its officials.[131]

In 2009, after a history of 17 years of government testing and spending of nearly $2.5 billion on research had produced almost no clearly proven efficacy of alternative therapies, Senator Harkin complained, "One of the purposes of this center was to investigate and validate alternative approaches. Quite frankly, I must say publicly that it has fallen short. It think quite frankly that in this center and in the office previously before it, most of its focus has been on disproving things rather than seeking out and approving."[139][145][146] Members of the scientific community criticized this comment as showing Senator Harkin did not understand the basics of scientific inquiry, which tests hypotheses, but never intentionally attempts to "validate approaches".[139] Members of the scientific and biomedical communities complained that after a history of 17 years of being tested, at a cost of over $2.5 Billion on testing scientifically and biologically implausible practices, almost no alternative therapy showed clear efficacy.[10] In 2009, the NCCAM's budget was increased to about $122 million.[139] Overall NIH funding for CAM research increased to $300 Million by 2009.[139] By 2009, Americans were spending $34 Billion annually on CAM.[147]

Since 2009, according to Art. 118a of the Swiss Federal Constitution, the Swiss Confederation and the Cantons of Switzerland shall within the scope of their powers ensure that consideration is given to complementary medicine.[148]

In 2012, the Journal of the American Medical Association (JAMA) published a criticism that study after study had been funded by NCCAM, but "failed to prove that complementary or alternative therapies are anything more than placebos".[149] The JAMA criticism pointed to large wasting of research money on testing scientifically implausible treatments, citing "NCCAM officials spending $374,000 to find that inhaling lemon and lavender scents does not promote wound healing; $750,000 to find that prayer does not cure AIDS or hasten recovery from breast-reconstruction surgery; $390,000 to find that ancient Indian remedies do not control type 2 diabetes; $700,000 to find that magnets do not treat arthritis, carpal tunnel syndrome, or migraine headaches; and $406,000 to find that coffee enemas do not cure pancreatic cancer."[149] It was pointed out that negative results from testing were generally ignored by the public, that people continue to "believe what they want to believe, arguing that it does not matter what the data show: They know what works for them".[149] Continued increasing use of CAM products was also blamed on the lack of FDA ability to regulate alternative products, where negative studies do not result in FDA warnings or FDA-mandated changes on labeling, whereby few consumers are aware that many claims of many supplements were found not to have not to be supported.[149]

By 2013, 50% of Americans were using CAM.[126] As of 2013[update], CAM medicinal products in Europe continued to be exempted from documented efficacy standards required of other medicinal products.[150]

In 2014 the NCCAM was renamed to the National Center for Complementary and Integrative Health (NCCIH) with a new charter requiring that 12 of the 18 council members shall be selected with a preference to selecting leading representatives of complementary and alternative medicine, 9 of the members must be licensed practitioners of alternative medicine, 6 members must be general public leaders in the fields of public policy, law, health policy, economics, and management, and 3 members must represent the interests of individual consumers of complementary and alternative medicine.[151]

Much of what is now categorized as alternative medicine was developed as independent, complete medical systems. These were developed long before biomedicine and use of scientific methods. Each system was developed in relatively isolated regions of the world where there was little or no medical contact with pre-scientific western medicine, or with each other's systems. Examples are traditional Chinese medicine and the Ayurvedic medicine of India.

Other alternative medicine practices, such as homeopathy, were developed in western Europe and in opposition to western medicine, at a time when western medicine was based on unscientific theories that were dogmatically imposed by western religious authorities. Homeopathy was developed prior to discovery of the basic principles of chemistry, which proved homeopathic remedies contained nothing but water. But homeopathy, with its remedies made of water, was harmless compared to the unscientific and dangerous orthodox western medicine practiced at that time, which included use of toxins and draining of blood, often resulting in permanent disfigurement or death.[114]

Other alternative practices such as chiropractic and osteopathic manipulative medicine were developed in the United States at a time that western medicine was beginning to incorporate scientific methods and theories, but the biomedical model was not yet totally dominant. Practices such as chiropractic and osteopathic, each considered to be irregular practices by the western medical establishment, also opposed each other, both rhetorically and politically with licensing legislation. Osteopathic practitioners added the courses and training of biomedicine to their licensing, and licensed Doctor of Osteopathic Medicine holders began diminishing use of the unscientific origins of the field. Without the original nonscientific practices and theories, osteopathic medicine is now considered the same as biomedicine.

Until the 1970s, western practitioners that were not part of the medical establishment were referred to "irregular practitioners", and were dismissed by the medical establishment as unscientific, as practicing quackery.[114] Irregular practice became increasingly marginalized as quackery and fraud, as western medicine increasingly incorporated scientific methods and discoveries, and had a corresponding increase in success of its treatments.

Dating from the 1970s, medical professionals, sociologists, anthropologists and other commentators noted the increasing visibility of a wide variety of health practices that had neither derived directly from nor been verified by biomedical science.[152] Since that time, those who have analyzed this trend have deliberated over the most apt language with which to describe this emergent health field.[152] A variety of terms have been used, including heterodox, irregular, fringe and alternative medicine while others, particularly medical commentators, have been satisfied to label them as instances of quackery.[152] The most persistent term has been alternative medicine but its use is problematic as it assumes a value-laden dichotomy between a medical fringe, implicitly of borderline acceptability at best, and a privileged medical orthodoxy, associated with validated medico-scientific norms.[153] The use of the category of alternative medicine has also been criticized as it cannot be studied as an independent entity but must be understood in terms of a regionally and temporally specific medical orthodoxy.[154] Its use can also be misleading as it may erroneously imply that a real medical alternative exists.[85] As with near-synonymous expressions, such as unorthodox, complementary, marginal, or quackery, these linguistic devices have served, in the context of processes of professionalisation and market competition, to establish the authority of official medicine and police the boundary between it and its unconventional rivals.[153]

An early instance of the influence of this modern, or western, scientific medicine outside Europe and North America is Peking Union Medical College.[155][n 15][n 16]

From a historical perspective, the emergence of alternative medicine, if not the term itself, is typically dated to the 19th century.[156] This is despite the fact that there are variants of Western non-conventional medicine that arose in the late-eighteenth century or earlier and some non-Western medical traditions, currently considered alternative in the West and elsewhere, which boast extended historical pedigrees.[153] Alternative medical systems, however, can only be said to exist when there is an identifiable, regularized and authoritative standard medical practice, such as arose in the West during the nineteenth century, to which they can function as an alternative.

During the late eighteenth and nineteenth centuries regular and irregular medical practitioners became more clearly differentiated throughout much of Europe and,[158] as the nineteenth century progressed, most Western states converged in the creation of legally delimited and semi-protected medical markets.[159] It is at this point that an "official" medicine, created in cooperation with the state and employing a scientific rhetoric of legitimacy, emerges as a recognizable entity and that the concept of alternative medicine as a historical category becomes tenable.[160]

As part of this process, professional adherents of mainstream medicine in countries such as Germany, France, and Britain increasingly invoked the scientific basis of their discipline as a means of engendering internal professional unity and of external differentiation in the face of sustained market competition from homeopaths, naturopaths, mesmerists and other nonconventional medical practitioners, finally achieving a degree of imperfect dominance through alliance with the state and the passage of regulatory legislation.[85][153] In the US the Johns Hopkins University School of Medicine, based in Baltimore, Maryland, opened in 1893, with William H. Welch and William Osler among the founding physicians, and was the first medical school devoted to teaching "German scientific medicine".[161]

Buttressed by increased authority arising from significant advances in the medical sciences of the late 19th century onwardsincluding development and application of the germ theory of disease by the chemist Louis Pasteur and the surgeon Joseph Lister, of microbiology co-founded by Robert Koch (in 1885 appointed professor of hygiene at the University of Berlin), and of the use of X-rays (Rntgen rays)the 1910 Flexner Report called upon American medical schools to follow the model of the Johns Hopkins School of Medicine, and adhere to mainstream science in their teaching and research. This was in a belief, mentioned in the Report's introduction, that the preliminary and professional training then prevailing in medical schools should be reformed, in view of the new means for diagnosing and combating disease made available the sciences on which medicine depended.[n 17][163]

Putative medical practices at the time that later became known as "alternative medicine" included homeopathy (founded in Germany in the early 19c.) and chiropractic (founded in North America in the late 19c.). These conflicted in principle with the developments in medical science upon which the Flexner reforms were based, and they have not become compatible with further advances of medical science such as listed in Timeline of medicine and medical technology, 19001999 and 2000present, nor have Ayurveda, acupuncture or other kinds of alternative medicine.[citation needed]

At the same time "Tropical medicine" was being developed as a specialist branch of western medicine in research establishments such as Liverpool School of Tropical Medicine founded in 1898 by Alfred Lewis Jones, London School of Hygiene & Tropical Medicine, founded in 1899 by Patrick Manson and Tulane University School of Public Health and Tropical Medicine, instituted in 1912. A distinction was being made between western scientific medicine and indigenous systems. An example is given by an official report about indigenous systems of medicine in India, including Ayurveda, submitted by Mohammad Usman of Madras and others in 1923. This stated that the first question the Committee considered was "to decide whether the indigenous systems of medicine were scientific or not".[164][165]

By the later twentieth century the term 'alternative medicine' entered public discourse,[n 18][168] but it was not always being used with the same meaning by all parties. Arnold S. Relman remarked in 1998 that in the best kind of medical practice, all proposed treatments must be tested objectively, and that in the end there will only be treatments that pass and those that do not, those that are proven worthwhile and those that are not. He asked 'Can there be any reasonable "alternative"?'[169] But also in 1998 the then Surgeon General of the United States, David Satcher,[170] issued public information about eight common alternative treatments (including acupuncture, holistic and massage), together with information about common diseases and conditions, on nutrition, diet, and lifestyle changes, and about helping consumers to decipher fraud and quackery, and to find healthcare centers and doctors who practiced alternative medicine.[171]

By 1990, approximately 60 million Americans had used one or more complementary or alternative therapies to address health issues, according to a nationwide survey in the US published in 1993 by David Eisenberg.[172] A study published in the November 11, 1998 issue of the Journal of the American Medical Association reported that 42% of Americans had used complementary and alternative therapies, up from 34% in 1990.[87] However, despite the growth in patient demand for complementary medicine, most of the early alternative/complementary medical centers failed.[173]

Mainly as a result of reforms following the Flexner Report of 1910[174]medical education in established medical schools in the US has generally not included alternative medicine as a teaching topic.[n 19] Typically, their teaching is based on current practice and scientific knowledge about: anatomy, physiology, histology, embryology, neuroanatomy, pathology, pharmacology, microbiology and immunology.[176] Medical schools' teaching includes such topics as doctor-patient communication, ethics, the art of medicine,[177] and engaging in complex clinical reasoning (medical decision-making).[178] Writing in 2002, Snyderman and Weil remarked that by the early twentieth century the Flexner model had helped to create the 20th-century academic health center, in which education, research, and practice were inseparable. While this had much improved medical practice by defining with increasing certainty the pathophysiological basis of disease, a single-minded focus on the pathophysiological had diverted much of mainstream American medicine from clinical conditions that were not well understood in mechanistic terms, and were not effectively treated by conventional therapies.[179]

By 2001 some form of CAM training was being offered by at least 75 out of 125 medical schools in the US.[180] Exceptionally, the School of Medicine of the University of Maryland, Baltimore includes a research institute for integrative medicine (a member entity of the Cochrane Collaboration).[181][182] Medical schools are responsible for conferring medical degrees, but a physician typically may not legally practice medicine until licensed by the local government authority. Licensed physicians in the US who have attended one of the established medical schools there have usually graduated Doctor of Medicine (MD).[183] All states require that applicants for MD licensure be graduates of an approved medical school and complete the United States Medical Licensing Exam (USMLE).[183]

The British Medical Association, in its publication Complementary Medicine, New Approach to Good Practice (1993), gave as a working definition of non-conventional therapies (including acupuncture, chiropractic and homeopathy): "...those forms of treatment which are not widely used by the orthodox health-care professions, and the skills of which are not part of the undergraduate curriculum of orthodox medical and paramedical health-care courses." By 2000 some medical schools in the UK were offering CAM familiarisation courses to undergraduate medical students while some were also offering modules specifically on CAM.[185]

The Cochrane Collaboration Complementary Medicine Field explains its "Scope and Topics" by giving a broad and general definition for complementary medicine as including practices and ideas outside the domain of conventional medicine in several countriesand defined by its users as preventing or treating illness, or promoting health and well being, and which complement mainstream medicine in three ways: by contributing to a common whole, by satisfying a demand not met by conventional practices, and by diversifying the conceptual framework of medicine.[186]

Proponents of an evidence-base for medicine[n 20][188][189][190][191] such as the Cochrane Collaboration (founded in 1993 and from 2011 providing input for WHO resolutions) take a position that all systematic reviews of treatments, whether "mainstream" or "alternative", ought to be held to the current standards of scientific method.[182] In a study titled Development and classification of an operational definition of complementary and alternative medicine for the Cochrane Collaboration (2011) it was proposed that indicators that a therapy is accepted include government licensing of practitioners, coverage by health insurance, statements of approval by government agencies, and recommendation as part of a practice guideline; and that if something is currently a standard, accepted therapy, then it is not likely to be widely considered as CAM.[68]

That alternative medicine has been on the rise "in countries where Western science and scientific method generally are accepted as the major foundations for healthcare, and 'evidence-based' practice is the dominant paradigm" was described as an "enigma" in the Medical Journal of Australia.[192]

Critics in the US say the expression is deceptive because it implies there is an effective alternative to science-based medicine, and that complementary is deceptive because it implies that the treatment increases the effectiveness of (complements) science-based medicine, while alternative medicines that have been tested nearly always have no measurable positive effect compared to a placebo.[5][193][194][195]

Some opponents, focused upon health fraud, misinformation, and quackery as public health problems in the US, are highly critical of alternative medicine, notably Wallace Sampson and Paul Kurtz founders of Scientific Review of Alternative Medicine and Stephen Barrett, co-founder of The National Council Against Health Fraud and webmaster of Quackwatch.[196] Grounds for opposing alternative medicine stated in the US and elsewhere include that:

Paul Offit proposed that "alternative medicine becomes quackery" in four ways, by:[46]

"CAM", meaning "complementary and alternative medicine", is not as well researched as conventional medicine, which undergoes intense research before release to the public.[86] Funding for research is also sparse making it difficult to do further research for effectiveness of CAM.[206] Most funding for CAM is funded by government agencies.[86] Proposed research for CAM are rejected by most private funding agencies because the results of research are not reliable.[86] The research for CAM has to meet certain standards from research ethics committees, which most CAM researchers find almost impossible to meet.[86] Even with the little research done on it, CAM has not been proven to be effective.[207]

Steven Novella, a neurologist at Yale School of Medicine, wrote that government funded studies of integrating alternative medicine techniques into the mainstream are "used to lend an appearance of legitimacy to treatments that are not legitimate."[208] Marcia Angell considered that critics felt that healthcare practices should be classified based solely on scientific evidence, and if a treatment had been rigorously tested and found safe and effective, science-based medicine will adopt it regardless of whether it was considered "alternative" to begin with.[25] It is possible for a method to change categories (proven vs. unproven), based on increased knowledge of its effectiveness or lack thereof. A prominent supporter of this position is George D. Lundberg, former editor of the Journal of the American Medical Association (JAMA).[47]

Writing in 1999 in CA: A Cancer Journal for Clinicians Barrie R. Cassileth mentioned a 1997 letter to the US Senate Subcommittee on Public Health and Safety, which had deplored the lack of critical thinking and scientific rigor in OAM-supported research, had been signed by four Nobel Laureates and other prominent scientists. (This was supported by the National Institutes of Health (NIH).)[209]

In March 2009 a staff writer for the Washington Post reported that the impending national discussion about broadening access to health care, improving medical practice and saving money was giving a group of scientists an opening to propose shutting down the National Center for Complementary and Alternative Medicine. They quoted one of these scientists, Steven Salzberg, a genome researcher and computational biologist at the University of Maryland, as saying "One of our concerns is that NIH is funding pseudoscience." They noted that the vast majority of studies were based on fundamental misunderstandings of physiology and disease, and had shown little or no effect.[208]

Writers such as Carl Sagan (1934-1996), a noted astrophysicist, advocate of scientific skepticism and the author of The demonhaunted world: science as a candle in the dark (1996), have described the lack of empirical evidence to support the existence of the putative energy fields on which these therapies are predicated.

The NCCIH budget has been criticized[208] because, despite the duration and intensity of studies to measure the efficacy of alternative medicine, there had been no effective CAM treatments supported by scientific evidence as of 2002[update], according to the QuackWatch website; the NCCIH budget has been on a sharp and sustained rise.[210] Critics of the Center argue that the plausibility of interventions such as botanical remedies, diet, relaxation therapies and yoga should not be used to support research on implausible interventions based on superstition and belief in the supernatural, and that the plausible methods can be studied just as well in other parts of NIH, where they should be made to compete on an equal footing with other research projects.[208]

Sampson has also pointed out that CAM tolerated contradiction without thorough reason and experiment.[211] Barrett has pointed out that there is a policy at the NIH of never saying something doesn't work only that a different version or dose might give different results.[10] Barrett also expressed concern that, just because some "alternatives" have merit, there is the impression that the rest deserve equal consideration and respect even though most are worthless, since they are all classified under the one heading of alternative medicine.[212]

A 2002 report on public attitudes and understanding issued by the US National Science Foundation defined the term "alternative medicine" as treatments that had not been proven effective using scientific methods, and described them as giving more weight to ancient traditions and anecdotes over biological science and clinical trials.[14]

English evolutionary biologist Richard Dawkins, in his 2003 book A Devil's Chaplain (chapter 4.4), defined alternative medicine as a "set of practices that cannot be tested, refuse to be tested, or consistently fail tests."[213] Another essay in the same book (chapter 1.4) quoted an article by John Diamond in The Independent: "There is really no such thing as alternative medicine, just medicine that works and medicine that doesn't."[32] Dawkins argued that if a technique is demonstrated effective in properly performed trials it ceases to be alternative and simply becomes medicine.[214]

Use of the terms "Complementary and alternative medicine (CAM)" and "alternative medicine" have been criticized.

Criticisms have come from individuals such as Wallace Sampson in an article in Annals of the New York Academy of Sciences, June 1995.[5] Sampson argued that proponents of alternative medicine often used loose or ambiguous terminology to create the appearance that a choice between "alternative" effective treatments existed when it did not, or that there was effectiveness or scientific validity when it did not exist, or to suggest that a dichotomy existed when it did not, or to suggest that consistency with science existed when it might not. Proponents meant the term alternative to imply that a patient had a choice between effective treatments when there was none; meant the word "conventional" or "mainstream" to suggest that the difference between alternative medicine and science-based medicine was the prevalence of use rather than alternative medicine's lack of scientific basis; that use of complementary or integrative was to suggest that purported supernatural energies of alternative medicine could enhance science-based medicine.

Stephen Barrett, founder and operator of Quackwatch, argues that practices labeled "alternative" should be reclassified as either genuine, experimental, or questionable. Here he defines genuine as being methods that have sound evidence for safety and effectiveness, experimental as being unproven but with a plausible rationale for effectiveness, and questionable as groundless without a scientifically plausible rationale.[212]

CAM is less regulated than conventional medicine.[86] There are ethical concerns about whether people who perform CAM have the proper knowledge to treat patients.[86] CAM is often done by non-physicians and does not operate with the same medical licensing laws as conventional medicine.[86] It is an issue of non-maleficence.[215]

According to two writers, Wallace Sampson and K. Butler, marketing is part of the training required in chiropractic education, and propaganda methods in alternative medicine have been traced back to those used by Hitler and Goebels in their promotion of pseudoscience in medicine.[5][216]

In November 2011 Edzard Ernst stated that the "level of misinformation about alternative medicine has now reached the point where it has become dangerous and unethical. So far, alternative medicine has remained an ethics-free zone. It is time to change this."[217] Ernst requested that Prince Charles recall two guides to alternative medicine published by the Foundation for Integrated Health, on the grounds that "[t]hey both contain numerous misleading and inaccurate claims concerning the supposed benefits of alternative medicine" and that "[t]he [British] nation cannot be served by promoting ineffective and sometimes dangerous alternative treatments."[218] In general, he believes that CAM can and should be subjected to scientific testing.[219][n 21]

A research methods expert and author of "Snake Oil Science", R. Barker Bausell, has stated that "it's become politically correct to investigate nonsense."[10] There are concerns that just having NIH support is being used to give unfounded "legitimacy to treatments that are not legitimate."[208]

Alternative medicine – Wikipedia, the free encyclopedia

Alternative medicine is any practice that is put forward as having the healing effects of medicine, but does not originate from evidence gathered using the scientific method,[n 1][n 2][n 3] is not part of biomedicine,[n 1][n 4][n 5][n 6] or is contradicted by scientific evidence or established science.[1][2][3] It consists of a wide range of health care practices, products and therapies, ranging from being biologically plausible but not well tested, to being directly contradicted by evidence and science, or even harmful or toxic.[n 4][1][3][4][5][6] Examples include new and traditional medicine practices such as homeopathy, naturopathy, chiropractic, energy medicine, various forms of acupuncture, traditional Chinese medicine, Ayurvedic medicine, and Christian faith healing. The treatments are those that are not part of the science-based healthcare system, and are not clearly backed by scientific evidence.[7][8][10] Despite significant expenditures on testing alternative medicine, including $2.5 billion spent by the United States government, almost none have shown any effectiveness greater than that of false treatments (placebo), and alternative medicine has been criticized by prominent figures in science and medicine as being quackery, nonsense, fraudulent, or unethical.[11][12]

Complementary medicine is alternative medicine used together with conventional medical treatment, in a belief not confirmed using the scientific method that it "complements" (improves the efficacy of) the treatment.[n 7][14][15][16]CAM is the abbreviation for complementary and alternative medicine.[17][18]Integrative medicine (or integrative health) is the combination of the practices and methods of alternative medicine with conventional medicine.[19]

Alternative medical diagnoses and treatments are not included as science-based treatments that are taught in medical schools, and are not used in medical practice where treatments are based on what is established using the scientific method. Alternative therapies lack such scientific validation, and their effectiveness is either unproved or disproved.[n 8][1][14][21][22] Alternative medicine is usually based on religion, tradition, superstition, belief in supernatural energies, pseudoscience, errors in reasoning, propaganda, or fraud.[1][2][3][14] Regulation and licensing of alternative medicine and health care providers varies from country to country, and state to state.

The scientific community has criticized alternative medicine as being based on misleading statements, quackery, pseudoscience, antiscience, fraud, or poor scientific methodology. Promoting alternative medicine has been called dangerous and unethical.[n 9][24] Testing alternative medicine has been called a waste of scarce medical research resources.[25][26] Critics have said "there is really no such thing as alternative medicine, just medicine that works and medicine that doesn't",[27] and "Can there be any reasonable 'alternative' [to medicine based on evidence]?"[28]

Alternative medicine consists of a wide range of health care practices, products, and therapies. The shared feature is a claim to heal that is not based on the scientific method. Alternative medicine practices are diverse in their foundations and methodologies.[7] Alternative medicine practices may be classified by their cultural origins or by the types of beliefs upon which they are based.[1][2][7][14] Methods may incorporate or base themselves on traditional medicinal practices of a particular culture, folk knowledge, supersition, spiritual beliefs, belief in supernatural energies (antiscience), pseudoscience, errors in reasoning, propaganda, fraud, new or different concepts of health and disease, and any bases other than being proven by scientific methods.[1][2][3][14] Different cultures may have their own unique traditional or belief based practices developed recently or over thousands of years, and specific practices or entire systems of practices.

Alternative medical systems can be based on common belief systems that are not consistent with facts of science, such as in naturopathy or homeopathy.[7]

Homeopathy is a system developed in a belief that a substance that causes the symptoms of a disease in healthy people will cure similar symptoms in sick people.[n 10] It was developed before knowledge of atoms and molecules, and of basic chemistry, which shows that repeated dilution as practiced in homeopathy produces only water and that homeopathy is scientifically implausible.[31][32][33][34] Homeopathy is considered quackery in the medical community.[35]

Naturopathic medicine is based on a belief that the body heals itself using a supernatural vital energy that guides bodily processes,[36] a view in conflict with the paradigm of evidence-based medicine.[37] Many naturopaths have opposed vaccination,[38] and "scientific evidence does not support claims that naturopathic medicine can cure cancer or any other disease".[39]

Alternative medical systems may be based on traditional medicine practices, such as traditional Chinese medicine, Ayurveda in India, or practices of other cultures around the world.[7]

Traditional Chinese medicine is a combination of traditional practices and beliefs developed over thousands of years in China, together with modifications made by the Communist party. Common practices include herbal medicine, acupuncture (insertion of needles in the body at specified points), massage (Tui na), exercise (qigong), and dietary therapy. The practices are based on belief in a supernatural energy called qi, considerations of Chinese Astrology and Chinese numerology, traditional use of herbs and other substances found in China, a belief that a map of the body is contained on the tongue which reflects changes in the body, and an incorrect model of the anatomy and physiology of internal organs.[1][40][41][42][43][44]

The Chinese Communist Party Chairman Mao Zedong, in response to the lack of modern medical practitioners, revived acupuncture and its theory was rewritten to adhere to the political, economic and logistic necessities of providing for the medical needs of China's population.[45][pageneeded] In the 1950s the "history" and theory of traditional Chinese medicine was rewritten as communist propaganda, at Mao's insistence, to correct the supposed "bourgeois thought of Western doctors of medicine".Acupuncture gained attention in the United States when President Richard Nixon visited China in 1972, and the delegation was shown a patient undergoing major surgery while fully awake, ostensibly receiving acupuncture rather than anesthesia. Later it was found that the patients selected for the surgery had both a high pain tolerance and received heavy indoctrination before the operation; these demonstration cases were also frequently receiving morphine surreptitiously through an intravenous drip that observers were told contained only fluids and nutrients.[40]Cochrane reviews found acupuncture is not effective for a wide range of conditions.[47] A systematic review of systematic reviews found that for reducing pain, real acupuncture was no better than sham acupuncture.[48] Although, other reviews have found that acupuncture is successful at reducing chronic pain, where as sham acupuncture was not found to be better than a placebo as well as no-acupuncture groups.[49]

Ayurvedic medicine is a traditional medicine of India. Ayurveda believes in the existence of three elemental substances, the doshas (called Vata, Pitta and Kapha), and states that a balance of the doshas results in health, while imbalance results in disease. Such disease-inducing imbalances can be adjusted and balanced using traditional herbs, minerals and heavy metals. Ayurveda stresses the use of plant-based medicines and treatments, with some animal products, and added minerals, including sulfur, arsenic, lead, copper sulfate.[citation needed]

Safety concerns have been raised about Ayurveda, with two U.S. studies finding about 20 percent of Ayurvedic Indian-manufactured patent medicines contained toxic levels of heavy metals such as lead, mercury and arsenic. Other concerns include the use of herbs containing toxic compounds and the lack of quality control in Ayurvedic facilities. Incidents of heavy metal poisoning have been attributed to the use of these compounds in the United States.[5][52][53][54]

Bases of belief may include belief in existence of supernatural energies undetected by the science of physics, as in biofields, or in belief in properties of the energies of physics that are inconsistent with the laws of physics, as in energy medicine.[7]

Biofield therapies are intended to influence energy fields that, it is purported, surround and penetrate the body.[7] Writers such as noted astrophysicist and advocate of skeptical thinking (Scientific skepticism) Carl Sagan (1934-1996) have described the lack of empirical evidence to support the existence of the putative energy fields on which these therapies are predicated.

Acupuncture is a component of traditional Chinese medicine. In acupuncture, it is believed that a supernatural energy called qi flows through the universe and through the body, and helps propel the blood, blockage of which leads to disease.[41] It is believed that insertion of needles at various parts of the body determined by astrological calculations can restore balance to the blocked flows, and thereby cure disease.[41]

Chiropractic was developed in the belief that manipulating the spine affects the flow of a supernatural vital energy and thereby affects health and disease.

In the western version of Japanese Reiki, the palms are placed on the patient near Chakras, believed to be centers of supernatural energies, in a belief that the supernatural energies can transferred from the palms of the practitioner, to heal the patient.

Bioelectromagnetic-based therapies use verifiable electromagnetic fields, such as pulsed fields, alternating-current, or direct-current fields in an unconventional manner.[7]Magnetic healing does not claim existence of supernatural energies, but asserts that magnets can be used to defy the laws of physics to influence health and disease.

Mind-body medicine takes a holistic approach to health that explores the interconnection between the mind, body, and spirit. It works under the premise that the mind can affect "bodily functions and symptoms".[7] Mind body medicines includes healing claims made in yoga, meditation, deep-breathing exercises, guided imagery, hypnotherapy, progressive relaxation, qi gong, and tai chi.[7]

Yoga, a method of traditional stretches, exercises, and meditations in Hinduism, may also be classified as an energy medicine insofar as its healing effects are believed to be due to a healing "life energy" that is absorbed into the body through the breath, and is thereby believed to treat a wide variety of illnesses and complaints.[56]

Since the 1990s, tai chi (t'ai chi ch'uan) classes that purely emphasise health have become popular in hospitals, clinics, as well as community and senior centers. This has occurred as the baby boomers generation has aged and the art's reputation as a low-stress training method for seniors has become better known.[57][58] There has been some divergence between those that say they practice t'ai chi ch'uan primarily for self-defence[citation needed], those that practice it for its aesthetic appeal (see wushu below), and those that are more interested in its benefits to physical and mental health.

Qigong, chi kung, or chi gung, is a practice of aligning body, breath, and mind for health, meditation, and martial arts training. With roots in traditional Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed as a practice to cultivate and balance qi (chi) or what has been translated as "life energy".[59]

Substance based practices use substances found in nature such as herbs, foods, non-vitamin supplements and megavitamins, animal and fungal products, and minerals, including use of these products in traditional medical practices that may also incorporate other methods.[7][12][60] Examples include healing claims for nonvitamin supplements, fish oil, Omega-3 fatty acid, glucosamine, echinacea, flaxseed oil, and ginseng.[61]Herbal medicine, or phytotherapy, includes not just the use of plant products, but may also include the use of animal and mineral products.[12] It is among the most commercially successful branches of alternative medicine, and includes the tablets, powders and elixirs that are sold as "nutritional supplements".[12] Only a very small percentage of these have been shown to have any efficacy, and there is little regulation as to standards and safety of their contents.[12] This may include use of known toxic substances, such as use of the poison lead in traditional Chinese medicine.[61]

Manipulative and body-based practices feature the manipulation or movement of body parts, such as is done in bodywork and chiropractic manipulation.

Osteopathic manipulative medicine, also known as osteopathic manipulative treatment, is a core set of techniques of osteopathy and osteopathic medicine distinguishing these fields from mainstream medicine.[62]

Religion based healing practices, such as use of prayer and the laying of hands in Christian faith healing, and shamanism, rely on belief in divine or spiritual intervention for healing.

Shamanism is a practice of many cultures around the world, in which a practitioner reaches an altered states of consciousness in order to encounter and interact with the spirit world or channel supernatural energies in the belief they can heal.[63]

Some alternative medicine practices may be based on pseudoscience, ignorance, or flawed reasoning.[64] This can lead to fraud.[1]

Practitioners of electricity and magnetism based healing methods may deliberately exploit a patient's ignorance of physics in order to defraud them.[14]

"Alternative medicine" is a loosely defined set of products, practices, and theories that are believed or perceived by their users to have the healing effects of medicine,[n 2][n 4] but whose effectiveness has not been clearly established using scientific methods,[n 2][n 3][1][3][20][22] whose theory and practice is not part of biomedicine,[n 4][n 1][n 5][n 6] or whose theories or practices are directly contradicted by scientific evidence or scientific principles used in biomedicine.[1][2][3] "Biomedicine" is that part of medical science that applies principles of biology, physiology, molecular biology, biophysics, and other natural sciences to clinical practice, using scientific methods to establish the effectiveness of that practice. Alternative medicine is a diverse group of medical and health care systems, practices, and products that originate outside of biomedicine,[n 1] are not considered part of biomedicine,[7] are not widely used by the biomedical healthcare professions,[69] and are not taught as skills practiced in biomedicine.[69] Unlike biomedicine,[n 1] an alternative medicine product or practice does not originate from the sciences or from using scientific methodology, but may instead be based on testimonials, religion, tradition, superstition, belief in supernatural energies, pseudoscience, errors in reasoning, propaganda, fraud, or other unscientific sources.[n 3][1][3][14] The expression "alternative medicine" refers to a diverse range of related and unrelated products, practices, and theories, originating from widely varying sources, cultures, theories, and belief systems, and ranging from biologically plausible practices and products and practices with some evidence, to practices and theories that are directly contradicted by basic science or clear evidence, and products that have proven to be ineffective or even toxic and harmful.[n 4][4][5]

"Alternative medicine", "complementary medicine", "holistic medicine", "natural medicine", "unorthodox medicine", "fringe medicine", "unconventional medicine", and "new age medicine" may be used interchangeably as having the same meaning (synonyms) in some contexts,[70][71][72] but may have different meanings in other contexts, for example, unorthodox medicine may refer to biomedicine that is different from what is commonly practiced, and fringe medicine may refer to biomedicine that is based on fringe science, which may be scientifically valid but is not mainstream.

The meaning of the term "alternative" in the expression "alternative medicine", is not that it is an actual effective alternative to medical science, although some alternative medicine promoters may use the loose terminology to give the appearance of effectiveness.[1]Marcia Angell stated that "alternative medicine" is "a new name for snake oil. There's medicine that works and medicine that doesn't work."[73] Loose terminology may also be used to suggest meaning that a dichotomy exists when it does not, e.g., the use of the expressions "western medicine" and "eastern medicine" to suggest that the difference is a cultural difference between the Asiatic east and the European west, rather than that the difference is between evidence-based medicine and treatments which don't work.[1]

"Complementary medicine" refers to use of alternative medical treatments alongside conventional medicine, in the belief that it increases the effectiveness of the science-based medicine.[74][75][76] An example of "complementary medicine" is use of acupuncture (sticking needles in the body to influence the flow of a supernatural energy), along with using science-based medicine, in the belief that the acupuncture increases the effectiveness or "complements" the science-based medicine.[76] "CAM" is an abbreviation for "complementary and alternative medicine".

The expression "Integrative medicine" (or "integrated medicine") is used in two different ways. One use refers to a belief that medicine based on science can be "integrated" with practices that are not. Another use refers only to a combination of alternative medical treatments with conventional treatments that have some scientific proof of efficacy, in which case it is identical with CAM.[19] "holistic medicine" (or holistic health) is an alternative medicine practice which claim to treat the "whole person" and not just the illness itself.

"Traditional medicine" and "folk medicine" refer to prescientific practices of a culture, not to what is traditionally practiced in cultures where medical science dominates. "Eastern medicine" typically refers to prescientific traditional medicines of Asia. "Western medicine", when referring to modern practice, typically refers to medical science, and not to alternative medicines practiced in the west (Europe and the Americas). "Western medicine", "biomedicine", "mainstream medicine", "medical science", "science-based medicine", "evidence-based medicine", "conventional medicine", "standard medicine", "orthodox medicine", "allopathic medicine", "dominant health system", and "medicine", are sometimes used interchangeably as having the same meaning, when contrasted with alternative medicine, but these terms may have different meanings in some contexts, e.g., some practices in medical science are not supported by rigorous scientific testing so "medical science" is not strictly identical with "science-based medicine", and "standard medical care" may refer to "best practice" when contrasted with other biomedicine that is less used or less recommended.[n 11][79]

Prominent members of the science[27][80] and biomedical science community[21] assert that it is not meaningful to define an alternative medicine that is separate from a conventional medicine, that the expressions "conventional medicine", "alternative medicine", "complementary medicine", "integrative medicine", and "holistic medicine" do not refer to anything at all.[21][27][80][81] Their criticisms of trying to make such artificial definitions include: "There's no such thing as conventional or alternative or complementary or integrative or holistic medicine. There's only medicine that works and medicine that doesn't;"[21][27][80] "By definition, alternative medicine has either not been proved to work, or been proved not to work. You know what they call alternative medicine that's been proved to work? Medicine;"[82] "There cannot be two kinds of medicine conventional and alternative. There is only medicine that has been adequately tested and medicine that has not, medicine that works and medicine that may or may not work. Once a treatment has been tested rigorously, it no longer matters whether it was considered alternative at the outset. If it is found to be reasonably safe and effective, it will be accepted;"[21] and "There is no alternative medicine. There is only scientifically proven, evidence-based medicine supported by solid data or unproven medicine, for which scientific evidence is lacking."[81]

Others in both the biomedical and CAM communities point out that CAM cannot be precisely defined because of the diversity of theories and practices it includes, and because the boundaries between CAM and biomedicine overlap, are porous, and change. The expression "complementary and alternative medicine" (CAM) resists easy definition because the health systems and practices to which it refers are diffuse and its boundaries are poorly defined.[4][n 12] Healthcare practices categorized as alternative may differ in their historical origin, theoretical basis, diagnostic technique, therapeutic practice and in their relationship to the medical mainstream. Some alternative therapies, including traditional Chinese medicine (TCM) and Ayurveda, have antique origins in East or South Asia and are entirely alternative medical systems;[87] others, such as homeopathy and chiropractic, have origins in Europe or the United States and emerged in the eighteenth and nineteenth centuries. Some, such as osteopathy and chiropractic, employ manipulative physical methods of treatment; others, such as meditation and prayer, are based on mind-body interventions. Treatments considered alternative in one location may be considered conventional in another.[90] Thus, chiropractic is not considered alternative in Denmark and likewise osteopathic medicine is no longer thought of as an alternative therapy in the United States.[90]

One common feature of all definitions of alternative medicine is its designation as "other than" conventional medicine. For example, the widely referenced descriptive definition of complementary and alternative medicine devised by the US National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health (NIH), states that it is "a group of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine."[7] For conventional medical practitioners, it does not necessarily follow that either it or its practitioners would no longer be considered alternative.[n 13]

Some definitions seek to specify alternative medicine in terms of its social and political marginality to mainstream healthcare.[95] This can refer to the lack of support that alternative therapies receive from the medical establishment and related bodies regarding access to research funding, sympathetic coverage in the medical press, or inclusion in the standard medical curriculum.[95] In 1993, the British Medical Association (BMA), one among many professional organizations who have attempted to define alternative medicine, stated that it[n 14] referred to "those forms of treatment which are not widely used by the conventional healthcare professions, and the skills of which are not taught as part of the undergraduate curriculum of conventional medical and paramedical healthcare courses".[69] In a US context, an influential definition coined in 1993 by the Harvard-based physician,[96] David M. Eisenberg,[97] characterized alternative medicine "as interventions neither taught widely in medical schools nor generally available in US hospitals".[98] These descriptive definitions are inadequate in the present-day when some conventional doctors offer alternative medical treatments and CAM introductory courses or modules can be offered as part of standard undergraduate medical training;[99] alternative medicine is taught in more than 50 per cent of US medical schools and increasingly US health insurers are willing to provide reimbursement for CAM therapies. In 1999, 7.7% of US hospitals reported using some form of CAM therapy; this proportion had risen to 37.7% by 2008.[101]

An expert panel at a conference hosted in 1995 by the US Office for Alternative Medicine (OAM),[102][n 15] devised a theoretical definition[102] of alternative medicine as "a broad domain of healing resources... other than those intrinsic to the politically dominant health system of a particular society or culture in a given historical period."[103] This definition has been widely adopted by CAM researchers,[102] cited by official government bodies such as the UK Department of Health,[104] attributed as the definition used by the Cochrane Collaboration,[105] and, with some modification,[dubious discuss] was preferred in the 2005 consensus report of the US Institute of Medicine, Complementary and Alternative Medicine in the United States.[n 4]

The 1995 OAM conference definition, an expansion of Eisenberg's 1993 formulation, is silent regarding questions of the medical effectiveness of alternative therapies.[106] Its proponents hold that it thus avoids relativism about differing forms of medical knowledge and, while it is an essentially political definition, this should not imply that the dominance of mainstream biomedicine is solely due to political forces.[106] According to this definition, alternative and mainstream medicine can only be differentiated with reference to what is "intrinsic to the politically dominant health system of a particular society of culture".[107] However, there is neither a reliable method to distinguish between cultures and subcultures, nor to attribute them as dominant or subordinate, nor any accepted criteria to determine the dominance of a cultural entity.[107] If the culture of a politically dominant healthcare system is held to be equivalent to the perspectives of those charged with the medical management of leading healthcare institutions and programs, the definition fails to recognize the potential for division either within such an elite or between a healthcare elite and the wider population.[107]

Normative definitions distinguish alternative medicine from the biomedical mainstream in its provision of therapies that are unproven, unvalidated or ineffective and support of theories which have no recognized scientific basis. These definitions characterize practices as constituting alternative medicine when, used independently or in place of evidence-based medicine, they are put forward as having the healing effects of medicine, but which are not based on evidence gathered with the scientific method.[7][14][21][74][75][109] Exemplifying this perspective, a 1998 editorial co-authored by Marcia Angell, a former editor of the New England Journal of Medicine, argued that:

This line of division has been subject to criticism, however, as not all forms of standard medical practice have adequately demonstrated evidence of benefit, [n 1][79] and it is also unlikely in most instances that conventional therapies, if proven to be ineffective, would ever be classified as CAM.[102]

Public information websites maintained by the governments of the US and of the UK make a distinction between "alternative medicine" and "complementary medicine", but mention that these two overlap. The National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health (NIH) (a part of the US Department of Health and Human Services) states that "alternative medicine" refers to using a non-mainstream approach in place of conventional medicine and that "complementary medicine" generally refers to using a non-mainstream approach together with conventional medicine, and comments that the boundaries between complementary and conventional medicine overlap and change with time.[7]

The National Health Service (NHS) website NHS Choices (owned by the UK Department of Health), adopting the terminology of NCCIH, states that when a treatment is used alongside conventional treatments, to help a patient cope with a health condition, and not as an alternative to conventional treatment, this use of treatments can be called "complementary medicine"; but when a treatment is used instead of conventional medicine, with the intention of treating or curing a health condition, the use can be called "alternative medicine".[111]

Similarly, the public information website maintained by the National Health and Medical Research Council (NHMRC) of the Commonwealth of Australia uses the acronym "CAM" for a wide range of health care practices, therapies, procedures and devices not within the domain of conventional medicine. In the Australian context this is stated to include acupuncture; aromatherapy; chiropractic; homeopathy; massage; meditation and relaxation therapies; naturopathy; osteopathy; reflexology, traditional Chinese medicine; and the use of vitamin supplements.[112]

The Danish National Board of Health's "Council for Alternative Medicine" (Sundhedsstyrelsens Rd for Alternativ Behandling (SRAB)), an independent institution under the National Board of Health (Danish: Sundhedsstyrelsen), uses the term "alternative medicine" for:

In General Guidelines for Methodologies on Research and Evaluation of Traditional Medicine, published in 2000 by the World Health Organization (WHO), complementary and alternative medicine were defined as a broad set of health care practices that are not part of that country's own tradition and are not integrated into the dominant health care system.[114] Some herbal therapies are mainstream in Europe but are alternative in the US.[116]

The history of alternative medicine may refer to the history of a group of diverse medical practices that were collectively promoted as "alternative medicine" beginning in the 1970s, to the collection of individual histories of members of that group, or to the history of western medical practices that were labeled "irregular practices" by the western medical establishment.[1][117][118][119][120] It includes the histories of complementary medicine and of integrative medicine. Before the 1970s, western practitioners that were not part of the increasingly science-based medical establishment were referred to "irregular practitioners", and were dismissed by the medical establishment as unscientific and as practicing quackery.[117][118] Until the 1970's, irregular practice became increasingly marginalized as quackery and fraud, as western medicine increasingly incorporated scientific methods and discoveries, and had a corresponding increase in success of its treatments.[119] In the 1970s, irregular practices were grouped with traditional practices of nonwestern cultures and with other unproven or disproven practices that were not part of biomedicine, with the entire group collectively marketed and promoted under the single expression "alternative medicine".[1][117][118][119][121]

Use of alternative medicine in the west began to rise following the counterculture movement of the 1960s, as part of the rising new age movement of the 1970s.[1][122][123] This was due to misleading mass marketing of "alternative medicine" being an effective "alternative" to biomedicine, changing social attitudes about not using chemicals and challenging the establishment and authority of any kind, sensitivity to giving equal measure to beliefs and practices of other cultures (cultural relativism), and growing frustration and desperation by patients about limitations and side effects of science-based medicine.[1][118][119][120][121][123][124] At the same time, in 1975, the American Medical Association, which played the central role in fighting quackery in the United States, abolished its quackery committee and closed down its Department of Investigation.[117]:xxi[124] By the early to mid 1970s the expression "alternative medicine" came into widespread use, and the expression became mass marketed as a collection of "natural" and effective treatment "alternatives" to science-based biomedicine.[1][124][125][126] By 1983, mass marketing of "alternative medicine" was so pervasive that the British Medical Journal (BMJ) pointed to "an apparently endless stream of books, articles, and radio and television programmes urge on the public the virtues of (alternative medicine) treatments ranging from meditation to drilling a hole in the skull to let in more oxygen".[124] In this 1983 article, the BMJ wrote, "one of the few growth industries in contemporary Britain is alternative medicine", noting that by 1983, "33% of patients with rheumatoid arthritis and 39% of those with backache admitted to having consulted an alternative practitioner".[124]

By about 1990, the American alternative medicine industry had grown to a $27 Billion per year, with polls showing 30% of Americans were using it.[123][127] Moreover, polls showed that Americans made more visits for alternative therapies than the total number of visits to primary care doctors, and American out-of-pocket spending (non-insurance spending) on alternative medicine was about equal to spending on biomedical doctors.[117]:172 In 1991, Time magazine ran a cover story, "The New Age of Alternative Medicine: Why New Age Medicine Is Catching On".[123][127] In 1993, the New England Journal of Medicine reported one in three Americans as using alternative medicine.[123] In 1993, the Public Broadcasting System ran a Bill Moyers special, Healing and the Mind, with Moyers commenting that "...people by the tens of millions are using alternative medicine. If established medicine does not understand that, they are going to lose their clients."[123]

Another explosive growth began in the 1990s, when senior level political figures began promoting alternative medicine, investing large sums of government medical research funds into testing alternative medicine, including testing of scientifically implausible treatments, and relaxing government regulation of alternative medicine products as compared to biomedical products.[1][117]:xxi[118][119][120][121][128][129] Beginning with a 1991 appropriation of $2 million for funding research of alternative medicine research, federal spending grew to a cumulative total of about $2.5 billion by 2009, with 50% of Americans using alternative medicine by 2013.[11][130]

In 1991, pointing to a need for testing because of the widespread use of alternative medicine without authoritative information on its efficacy, United States Senator Tom Harkin used $2 million of his discretionary funds to create the Office for the Study of Unconventional Medical Practices (OSUMP), later renamed to be the Office of Alternative Medicine (OAM).[117]:170[131][132] The OAM was created to be within the National Institute of Health (NIH), the scientifically prestigious primary agency of the United States government responsible for biomedical and health-related research.[117]:170[131][132] The mandate was to investigate, evaluate, and validate effective alternative medicine treatments, and alert the public as the results of testing its efficacy.[127][131][132][133]

Sen. Harkin had become convinced his allergies were cured by taking bee pollen pills, and was urged to make the spending by two of his influential constituents.[127][131][132] Bedell, a longtime friend of Sen. Harkin, was a former member of the United States House of Representatives who believed that alternative medicine had twice cured him of diseases after mainstream medicine had failed, claiming that cow's milk colostrum cured his Lyme disease, and an herbal derivative from camphor had prevented post surgical recurrence of his prostate cancer.[117][127] Wiewel was a promoter of unproven cancer treatments involving a mixture of blood sera that the Food and Drug Administration had banned from being imported.[127] Both Bedell and Wiewel became members of the advisory panel for the OAM. The company that sold the bee pollen was later fined by the Federal Trade Commission for making false health claims about their bee-pollen products reversing the aging process, curing allergies, and helping with weight loss.[134]

In 1993, Britain's Prince Charles, who claimed that homeopathy and other alternative medicine was an effective alternative to biomedicine, established the Foundation for Integrated Health (FIH), as a charity to explore "how safe, proven complementary therapies can work in conjunction with mainstream medicine".[135] The FIH received government funding through grants from Britain's Department of Health.[135]

In 1994, Sen. Harkin (D) and Senator Orrin Hatch (R) introduced the Dietary Supplement Health and Education Act (DSHEA).[136][137] The act reduced authority of the FDA to monitor products sold as "natural" treatments.[136] Labeling standards were reduced to allow health claims for supplements based only on unconfirmed preliminary studies that were not subjected to scientific peer review, and the act made it more difficult for the FDA to promptly seize products or demand proof of safety where there was evidence of a product being dangerous.[137] The Act became known as the "The 1993 Snake Oil Protection Act" following a New York Times editorial under that name.[136]

Senator Harkin complained about the "unbendable rules of randomized clinical trials", citing his use of bee pollen to treat his allergies, which he claimed to be effective even though it was biologically implausible and efficacy was not established using scientific methods.[131][138] Sen. Harkin asserted that claims for alternative medicine efficacy be allowed not only without conventional scientific testing, even when they are biologically implausible, "It is not necessary for the scientific community to understand the process before the American public can benefit from these therapies."[136] Following passage of the act, sales rose from about $4 billion in 1994, to $20 billion by the end of 2000, at the same time as evidence of their lack of efficacy or harmful effects grew.[136] Senator Harkin came into open public conflict with the first OAM Director Joseph M. Jacobs and OAM board members from the scientific and biomedical community.[132] Jacobs' insistence on rigorous scientific methodology caused friction with Senator Harkin.[131][138][139] Increasing political resistance to the use of scientific methodology was publicly criticized by Dr. Jacobs and another OAM board member complained that "nonsense has trickled down to every aspect of this office".[131][138] In 1994, Senator Harkin appeared on television with cancer patients who blamed Dr. Jacobs for blocking their access to untested cancer treatment, leading Jacobs to resign in frustration.[131][138]

In 1995, Wayne Jonas, a promoter of homeopathy and political ally of Senator Harkin, became the director of the OAM, and continued in that role until 1999.[140] In 1997, the NCCAM budget was increased from $12 million to $20 million annually.[141] From 1990 to 1997, use of alternative medicine in the US increased by 25%, with a corresponding 50% increase in expenditures.[142] The OAM drew increasing criticism from eminent members of the scientific community with letters to the Senate Appropriations Committee when discussion of renewal of funding OAM came up.[117]:175 Nobel laureate Paul Berg wrote that prestigious NIH should not be degraded to act as a cover for quackery, calling the OAM "an embarrassment to serious scientists."[117]:175[141] The president of the American Physical Society wrote complaining that the government was spending money on testing products and practices that "violate basic laws of physics and more clearly resemble witchcraft".[117]:175[141] In 1998, the President of the North Carolina Medical Association publicly called for shutting down the OAM.[143]

In 1998, NIH director and Nobel laureate Harold Varmus came into conflict with Senator Harkin by pushing to have more NIH control of alternative medicine research.[144] The NIH Director placed the OAM under more strict scientific NIH control.[141][144] Senator Harkin responded by elevating OAM into an independent NIH "center", just short of being its own "institute", and renamed to be the National Center for Complementary and Alternative Medicine (NCCAM). NCCAM had a mandate to promote a more rigorous and scientific approach to the study of alternative medicine, research training and career development, outreach, and "integration". In 1999, the NCCAM budget was increased from $20 million to $50 million.[143][144] The United States Congress approved the appropriations without dissent. In 2000, the budget was increased to about $68 million, in 2001 to $90 million, in 2002 to $104 million, and in 2003, to $113 million.[143]

In 2004, modifications of the European Parliament's 2001 Directive 2001/83/EC, regulating all medicine products, were made with the expectation of influencing development of the European market for alternative medicine products.[145] Regulation of alternative medicine in Europe was loosened with "a simplified registration procedure" for traditional herbal medicinal products.[145][146] Plausible "efficacy" for traditional medicine was redefined to be based on long term popularity and testimonials ("the pharmacological effects or efficacy of the medicinal product are plausible on the basis of long-standing use and experience."), without scientific testing.[145][146] The Committee on Herbal Medicinal Products (HMPC) was created within the European Medicines Agency in London (EMEA). A special working group was established for homeopathic remedies under the Heads of Medicines Agencies.[145]

Through 2004, alternative medicine that was traditional to Germany continued to be a regular part of the health care system, including homeopathy and anthroposophic medicine.[145] The German Medicines Act mandated that science-based medical authorities consider the "particular characteristics" of complementary and alternative medicines.[145] By 2004, homeopathy had grown to be the most used alternative therapy in France, growing from 16% of the population using homeopathic medicine in 1982, to 29% by 1987, 36% percent by 1992, and 62% of French mothers using homeopathic medicines by 2004, with 94.5% of French pharmacists advising pregnant women to use homeopathic remedies.[147] As of 2004[update], 100 million people in India depended solely on traditional German homeopathic remedies for their medical care.[148] As of 2010[update], homeopathic remedies continued to be the leading alternative treatment used by European physicians.[147] By 2005, sales of homeopathic remedies and anthroposophical medicine had grown to $930 million Euros, a 60% increase from 1995.[147][149]

In 2008, London's The Times published a letter from Edzard Ernst that asked the FIH to recall two guides promoting alternative medicine, saying: "the majority of alternative therapies appear to be clinically ineffective, and many are downright dangerous." In 2010, Brittan's FIH closed after allegations of fraud and money laundering led to arrests of its officials.[135]

In 2009, after a history of 17 years of government testing and spending of nearly $2.5 billion on research had produced almost no clearly proven efficacy of alternative therapies, Senator Harkin complained, "One of the purposes of this center was to investigate and validate alternative approaches. Quite frankly, I must say publicly that it has fallen short. It think quite frankly that in this center and in the office previously before it, most of its focus has been on disproving things rather than seeking out and approving."[144][150][151] Members of the scientific community criticized this comment as showing Senator Harkin did not understand the basics of scientific inquiry, which tests hypotheses, but never intentionally attempts to "validate approaches".[144] Members of the scientific and biomedical communities complained that after a history of 17 years of being tested, at a cost of over $2.5 Billion on testing scientifically and biologically implausible practices, almost no alternative therapy showed clear efficacy.[11] In 2009, the NCCAM's budget was increased to about $122 million.[144] Overall NIH funding for CAM research increased to $300 Million by 2009.[144] By 2009, Americans were spending $34 Billion annually on CAM.[152]

Since 2009, according to Art. 118a of the Swiss Federal Constitution, the Swiss Confederation and the Cantons of Switzerland shall within the scope of their powers ensure that consideration is given to complementary medicine.[153]

In 2012, the Journal of the American Medical Association (JAMA) published a criticism that study after study had been funded by NCCAM, but "failed to prove that complementary or alternative therapies are anything more than placebos".[154] The JAMA criticism pointed to large wasting of research money on testing scientifically implausible treatments, citing "NCCAM officials spending $374,000 to find that inhaling lemon and lavender scents does not promote wound healing; $750,000 to find that prayer does not cure AIDS or hasten recovery from breast-reconstruction surgery; $390,000 to find that ancient Indian remedies do not control type 2 diabetes; $700,000 to find that magnets do not treat arthritis, carpal tunnel syndrome, or migraine headaches; and $406,000 to find that coffee enemas do not cure pancreatic cancer."[154] It was pointed out that negative results from testing were generally ignored by the public, that people continue to "believe what they want to believe, arguing that it does not matter what the data show: They know what works for them".[154] Continued increasing use of CAM products was also blamed on the lack of FDA ability to regulate alternative products, where negative studies do not result in FDA warnings or FDA-mandated changes on labeling, whereby few consumers are aware that many claims of many supplements were found not to have not to be supported.[154]

By 2013, 50% of Americans were using CAM.[130] As of 2013[update], CAM medicinal products in Europe continued to be exempted from documented efficacy standards required of other medicinal products.[155]

In 2014 the NCCAM was renamed to the National Center for Complementary and Integrative Health (NCCIH) with a new charter requiring that 12 of the 18 council members shall be selected with a preference to selecting leading representatives of complementary and alternative medicine, 9 of the members must be licensed practitioners of alternative medicine, 6 members must be general public leaders in the fields of public policy, law, health policy, economics, and management, and 3 members must represent the interests of individual consumers of complementary and alternative medicine.[156]

Much of what is now categorized as alternative medicine was developed as independent, complete medical systems. These were developed long before biomedicine and use of scientific methods. Each system was developed in relatively isolated regions of the world where there was little or no medical contact with pre-scientific western medicine, or with each other's systems. Examples are traditional Chinese medicine and the Ayurvedic medicine of India.

Other alternative medicine practices, such as homeopathy, were developed in western Europe and in opposition to western medicine, at a time when western medicine was based on unscientific theories that were dogmatically imposed by western religious authorities. Homeopathy was developed prior to discovery of the basic principles of chemistry, which proved homeopathic remedies contained nothing but water. But homeopathy, with its remedies made of water, was harmless compared to the unscientific and dangerous orthodox western medicine practiced at that time, which included use of toxins and draining of blood, often resulting in permanent disfigurement or death.[118]

Other alternative practices such as chiropractic and osteopathic manipulative medicine were developed in the United States at a time that western medicine was beginning to incorporate scientific methods and theories, but the biomedical model was not yet totally dominant. Practices such as chiropractic and osteopathic, each considered to be irregular practices by the western medical establishment, also opposed each other, both rhetorically and politically with licensing legislation. Osteopathic practitioners added the courses and training of biomedicine to their licensing, and licensed Doctor of Osteopathic Medicine holders began diminishing use of the unscientific origins of the field. Without the original nonscientific practices and theories, osteopathic medicine is now considered the same as biomedicine.

Until the 1970s, western practitioners that were not part of the medical establishment were referred to "irregular practitioners", and were dismissed by the medical establishment as unscientific, as practicing quackery.[118] Irregular practice became increasingly marginalized as quackery and fraud, as western medicine increasingly incorporated scientific methods and discoveries, and had a corresponding increase in success of its treatments.

Dating from the 1970s, medical professionals, sociologists, anthropologists and other commentators noted the increasing visibility of a wide variety of health practices that had neither derived directly from nor been verified by biomedical science.[157] Since that time, those who have analyzed this trend have deliberated over the most apt language with which to describe this emergent health field.[157] A variety of terms have been used, including heterodox, irregular, fringe and alternative medicine while others, particularly medical commentators, have been satisfied to label them as instances of quackery.[157] The most persistent term has been alternative medicine but its use is problematic as it assumes a value-laden dichotomy between a medical fringe, implicitly of borderline acceptability at best, and a privileged medical orthodoxy, associated with validated medico-scientific norms.[158] The use of the category of alternative medicine has also been criticized as it cannot be studied as an independent entity but must be understood in terms of a regionally and temporally specific medical orthodoxy.[159] Its use can also be misleading as it may erroneously imply that a real medical alternative exists.[160] As with near-synonymous expressions, such as unorthodox, complementary, marginal, or quackery, these linguistic devices have served, in the context of processes of professionalisation and market competition, to establish the authority of official medicine and police the boundary between it and its unconventional rivals.[158]

An early instance of the influence of this modern, or western, scientific medicine outside Europe and North America is Peking Union Medical College.[161][n 16][n 17]

From a historical perspective, the emergence of alternative medicine, if not the term itself, is typically dated to the 19th century.[162] This is despite the fact that there are variants of Western non-conventional medicine that arose in the late-eighteenth century or earlier and some non-Western medical traditions, currently considered alternative in the West and elsewhere, which boast extended historical pedigrees.[158] Alternative medical systems, however, can only be said to exist when there is an identifiable, regularized and authoritative standard medical practice, such as arose in the West during the nineteenth-century, to which they can function as an alternative.

During the late eighteenth and nineteenth centuries regular and irregular medical practitioners became more clearly differentiated throughout much of Europe and,[164] as the nineteenth century progressed, most Western states converged in the creation of legally delimited and semi-protected medical markets.[165] It is at this point that an "official" medicine, created in cooperation with the state and employing a scientific rhetoric of legitimacy, emerges as a recognizable entity and that the concept of alternative medicine as a historical category becomes tenable.[166]

As part of this process, professional adherents of mainstream medicine in countries such as Germany, France, and Britain increasingly invoked the scientific basis of their discipline as a means of engendering internal professional unity and of external differentiation in the face of sustained market competition from homeopaths, naturopaths, mesmerists and other nonconventional medical practitioners, finally achieving a degree of imperfect dominance through alliance with the state and the passage of regulatory legislation.[158][160] In the US the Johns Hopkins University School of Medicine, based in Baltimore, Maryland, opened in 1893, with William H. Welch and William Osler among the founding physicians, and was the first medical school devoted to teaching "German scientific medicine".[167]

Buttressed by the increased authority arising from significant advances in the medical sciences of the late 19th century onwardsincluding the development and application of the germ theory of disease by the chemist Louis Pasteur and the surgeon Joseph Lister, of microbiology co-founded by Robert Koch (in 1885 appointed professor of hygiene at the University of Berlin), and of the use of X-rays (Rntgen rays)the 1910 Flexner Report called upon American medical schools to follow the model set by the Johns Hopkins School of Medicine and adhere to mainstream science in their teaching and research. This was in a belief, mentioned in the Report's introduction, that the preliminary and professional training then prevailing in medical schools should be reformed in view of the new means for diagnosing and combating disease being made available to physicians and surgeons by the sciences on which medicine depended.[n 18][169]

Among putative medical practices available at the time which later became known as "alternative medicine" were homeopathy (founded in Germany in the early 19c.) and chiropractic (founded in North America in the late 19c.). These conflicted in principle with the developments in medical science upon which the Flexner reforms were based, and they have not become compatible with further advances of medical science such as listed in Timeline of medicine and medical technology, 19001999 and 2000present, nor have Ayurveda, acupuncture or other kinds of alternative medicine.[citation needed]

At the same time "Tropical medicine" was being developed as a specialist branch of western medicine in research establishments such as Liverpool School of Tropical Medicine founded in 1898 by Alfred Lewis Jones, London School of Hygiene & Tropical Medicine, founded in 1899 by Patrick Manson and Tulane University School of Public Health and Tropical Medicine, instituted in 1912. A distinction was being made between western scientific medicine and indigenous systems. An example is given by an official report about indigenous systems of medicine in India, including Ayurveda, submitted by Mohammad Usman of Madras and others in 1923. This stated that the first question the Committee considered was "to decide whether the indigenous systems of medicine were scientific or not".[170][171]

By the later twentieth century the term 'alternative medicine' entered public discourse,[n 19][174] but it was not always being used with the same meaning by all parties. Arnold S. Relman remarked in 1998 that in the best kind of medical practice, all proposed treatments must be tested objectively, and that in the end there will only be treatments that pass and those that do not, those that are proven worthwhile and those that are not. He asked 'Can there be any reasonable "alternative"?'[28] But also in 1998 the then Surgeon General of the United States, David Satcher,[175] issued public information about eight common alternative treatments (including acupuncture, holistic and massage), together with information about common diseases and conditions, on nutrition, diet, and lifestyle changes, and about helping consumers to decipher fraud and quackery, and to find healthcare centers and doctors who practiced alternative medicine.[176]

By 1990, approximately 60 million Americans had used one or more complementary or alternative therapies to address health issues, according to a nationwide survey in the US published in 1993 by David Eisenberg.[177] A study published in the November 11, 1998 issue of the Journal of the American Medical Association reported that 42% of Americans had used complementary and alternative therapies, up from 34% in 1990.[142] However, despite the growth in patient demand for complementary medicine, most of the early alternative/complementary medical centers failed.[178]

Mainly as a result of reforms following the Flexner Report of 1910[179]medical education in established medical schools in the US has generally not included alternative medicine as a teaching topic.[n 20] Typically, their teaching is based on current practice and scientific knowledge about: anatomy, physiology, histology, embryology, neuroanatomy, pathology, pharmacology, microbiology and immunology.[181] Medical schools' teaching includes such topics as doctor-patient communication, ethics, the art of medicine,[182] and engaging in complex clinical reasoning (medical decision-making).[183] Writing in 2002, Snyderman and Weil remarked that by the early twentieth century the Flexner model had helped to create the 20th-century academic health center in which education, research and practice were inseparable. While this had much improved medical practice by defining with increasing certainty the pathophysiological basis of disease, a single-minded focus on the pathophysiological had diverted much of mainstream American medicine from clinical conditions which were not well understood in mechanistic terms and were not effectively treated by conventional therapies.[184]

By 2001 some form of CAM training was being offered by at least 75 out of 125 medical schools in the US.[185] Exceptionally, the School of Medicine of the University of Maryland, Baltimore includes a research institute for integrative medicine (a member entity of the Cochrane Collaboration).[186][187] Medical schools are responsible for conferring medical degrees, but a physician typically may not legally practice medicine until licensed by the local government authority. Licensed physicians in the US who have attended one of the established medical schools there have usually graduated Doctor of Medicine (MD).[188] All states require that applicants for MD licensure be graduates of an approved medical school and complete the United States Medical Licensing Exam (USMLE).[188]

The British Medical Association, in its publication Complementary Medicine, New Approach to Good Practice (1993), gave as a working definition of non-conventional therapies (including acupuncture, chiropractic and homeopathy): "those forms of treatment which are not widely used by the orthodox health-care professions, and the skills of which are not part of the undergraduate curriculum of orthodox medical and paramedical health-care courses". By 2000 some medical schools in the UK were offering CAM familiarisation courses to undergraduate medical students while some were also offering modules specifically on CAM.[190]

The Cochrane Collaboration Complementary Medicine Field explains its "Scope and Topics" by giving a broad and general definition for complementary medicine as including practices and ideas which are outside the domain of conventional medicine in several countries and defined by its users as preventing or treating illness, or promoting health and well being, and which complement mainstream medicine in three ways: by contributing to a common whole, by satisfying a demand not met by conventional practices, and by diversifying the conceptual framework of medicine.[191]

Proponents of an evidence-base for medicine[n 21][193][194][195][196] such as the Cochrane Collaboration (founded in 1993 and from 2011 providing input for WHO resolutions) take a position that all systematic reviews of treatments, whether "mainstream" or "alternative", ought to be held to the current standards of scientific method.[187] In a study titled Development and classification of an operational definition of complementary and alternative medicine for the Cochrane Collaboration (2011) it was proposed that indicators that a therapy is accepted include government licensing of practitioners, coverage by health insurance, statements of approval by government agencies, and recommendation as part of a practice guideline; and that if something is currently a standard, accepted therapy, then it is not likely to be widely considered as CAM.[102]

That alternative medicine has been on the rise "in countries where Western science and scientific method generally are accepted as the major foundations for healthcare, and 'evidence-based' practice is the dominant paradigm" was described as an "enigma" in the Medical Journal of Australia.[197]

Critics in the US say the expression is deceptive because it implies there is an effective alternative to science-based medicine, and that complementary is deceptive because the word implies that the treatment increases the effectiveness of (complements) science-based medicine, while alternative medicines which have been tested nearly always have no measurable positive effect compared to a placebo.[1][198][199][200]

Some opponents, focused upon health fraud, misinformation, and quackery as public health problems in the US, are highly critical of alternative medicine, notably Wallace Sampson and Paul Kurtz founders of Scientific Review of Alternative Medicine and Stephen Barrett, co-founder of The National Council Against Health Fraud and webmaster of Quackwatch.[201] Grounds for opposing alternative medicine which have been stated in the US and elsewhere are:

Paul Offit has proposed four ways that "alternative medicine becomes quackery":[80]

A United States government agency, the National Center on Complementary and Integrative Health (NCCIH), has created its own classification system for branches of complementary and alternative medicine. It classifies complementary and alternative therapies into five major groups, which have some overlap and two types of energy medicine are distinguished: one, "Veritable" involving scientifically observable energy, including magnet therapy, colorpuncture and light therapy; the other "Putative" which invoke physically undetectable or unverifiable energy.[210]

Alternative medicine practices and beliefs are diverse in their foundations and methodologies. The wide range of treatments and practices referred to as alternative medicine includes some stemming from nineteenth century North America, such as chiropractic and naturopathy, others, mentioned by Jtte, that originated in eighteenth- and nineteenth-century Germany, such as homeopathy and hydropathy,[160] and some that have originated in China or India, while African, Caribbean, Pacific Island, Native American, and other regional cultures have traditional medical systems as diverse as their diversity of cultures.[7]

Examples of CAM as a broader term for unorthodox treatment and diagnosis of illnesses, disease, infections, etc.,[211] include yoga, acupuncture, aromatherapy, chiropractic, herbalism, homeopathy, hypnotherapy, massage, osteopathy, reflexology, relaxation therapies, spiritual healing and tai chi.[211] CAM differs from conventional medicine. It is normally private medicine and not covered by health insurance.[211] It is paid out of pocket by the patient and is an expensive treatment.[211] CAM tends to be a treatment for upper class or more educated people.[142]

The NCCIH classification system is -

Alternative therapies based on electricity or magnetism use verifiable electromagnetic fields, such as pulsed fields, alternating-current, or direct-current fields in an unconventional manner rather than claiming the existence of imponderable or supernatural energies.[7]

Substance based practices use substances found in nature such as herbs, foods, non-vitamin supplements and megavitamins, and minerals, and includes traditional herbal remedies with herbs specific to regions in which the cultural practices arose.[7] Nonvitamin supplements include fish oil, Omega-3 fatty acid, glucosamine, echinacea, flaxseed oil or pills, and ginseng, when used under a claim to have healing effects.[61]

Mind-body interventions, working under the premise that the mind can affect "bodily functions and symptoms",[7] include healing claims made in hypnotherapy,[212] and in guided imagery, meditation, progressive relaxation, qi gong, tai chi and yoga.[7] Meditation practices including mantra meditation, mindfulness meditation, yoga, tai chi, and qi gong have many uncertainties. According to an AHRQ review, the available evidence on meditation practices through September 2005 is of poor methodological quality and definite conclusions on the effects of meditation in healthcare cannot be made using existing research.[213][214]

Naturopathy is based on a belief in vitalism, which posits that a special energy called vital energy or vital force guides bodily processes such as metabolism, reproduction, growth, and adaptation.[36] The term was coined in 1895[215] by John Scheel and popularized by Benedict Lust, the "father of U.S. naturopathy".[216] Today, naturopathy is primarily practiced in the United States and Canada.[217] Naturopaths in unregulated jurisdictions may use the Naturopathic Doctor designation or other titles regardless of level of education.[218]
