While products labeled as homeopathic are generally labeled as highly diluted, some of these products have been found to contain measurable amounts of active ingredients and therefore could cause significant patient harm
Under the Federal Food, Drug, and Cosmetic Act, homeopathic products are subject to the same requirements related to approval, adulteration and misbranding as other drug products. There are currently no homeopathic products approved by FDA.
Homeopathy or homoeopathy is a pseudoscientific[1] system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths or homeopathic physicians,[2] believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called similia similibus curentur, or "like cures like".[3] Homeopathic preparations are termed remedies and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product.[4] Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent "remember" the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease.[5]
Homeopathy achieved its greatest popularity in the 19th century. It was introduced to the United States in 1825, and the first American homeopathic school opened in 1835. Throughout the 19th century, dozens of homeopathic institutions appeared in Europe and the United States. During this period, homeopathy was able to appear relatively successful, as other forms of treatment could be harmful and ineffective. By the end of the century the practice began to wane, with the last exclusively homeopathic medical school in the United States closing in 1920. During the 1970s, homeopathy made a significant comeback, with sales of some homeopathic products increasing tenfold. The trend corresponded with the rise of the New Age movement, and may be in part due to chemophobia, an irrational aversion to synthetic chemicals, and the longer consultation times homeopathic practitioners provided.
In the 21st century, a series of meta-analyses have shown that the therapeutic claims of homeopathy lack scientific justification. As a result, national and international bodies have recommended the withdrawal of government funding for homeopathy in healthcare. National bodies from Australia, the United Kingdom, Switzerland and France, as well as the European Academies' Science Advisory Council and the Russian Academy of Sciences have all concluded that homeopathy is ineffective, and recommended against the practice receiving any further funding.[17][18][19][20] The National Health Service in England no longer provides funding for homeopathic remedies and asked the Department of Health to add homeopathic remedies to the list of forbidden prescription items.[21][22][23] France removed funding in 2021,[24][25] while Spain has also announced moves to ban homeopathy and other pseudotherapies from health centers.[26]
Homeopathy was created in 1796 by Samuel Hahnemann.[27] Hahnemann rejected the mainstream medicine of the late 18th century as irrational and inadvisable, because it was largely ineffective and often harmful.[28][29] He advocated the use of single drugs at lower doses and promoted an immaterial, vitalistic view of how living organisms function.[30] The term homeopathy was coined by Hahnemann and first appeared in print in 1807.[31] He also coined the expression "allopathic medicine", which was used to pejoratively refer to traditional Western medicine.[32]
Hahnemann began to test what effects various substances may produce in humans, a procedure later called "homeopathic proving". These tests required subjects to test the effects of ingesting substances by recording all their symptoms as well as the ancillary conditions under which they appeared.[38] He published a collection of provings in 1805, and a second collection of 65 preparations appeared in his book, Materia Medica Pura (1810).[39]
As Hahnemann believed that large doses of drugs that caused similar symptoms would only aggravate illness, he advocated for extreme dilutions. A technique was devised for making dilutions that Hahnemann claimed would preserve the substance's therapeutic properties while removing its harmful effects.[40] Hahnemann believed that this process enhanced "the spirit-like medicinal powers of the crude substances".[41] He gathered and published an overview of his new medical system in his book, The Organon of the Healing Art (1810), with a sixth edition published in 1921 that homeopaths still use today.[42]
In the Organon, Hahnemann introduced the concept of "miasms" as the "infectious principles" underlying chronic disease[43] and as "peculiar morbid derangement[s] of vital force".[44] Hahnemann associated each miasm with specific diseases, and thought that initial exposure to miasms causes local symptoms, such as skin or venereal diseases. His assertion was that if these symptoms were suppressed by medication, the cause went deeper and began to manifest itself as diseases of the internal organs.[45] Homeopathy maintains that treating diseases by directly alleviating their symptoms, as is sometimes done in conventional medicine, is ineffective because all "disease can generally be traced to some latent, deep-seated, underlying chronic, or inherited tendency".[46] The underlying imputed miasm still remains, and deep-seated ailments can be corrected only by removing the deeper disturbance of the vital force.[47]
Hahnemann's hypotheses for miasms originally presented only three local symptoms: psora (the itch), syphilis (venereal disease) or sycosis (fig-wart disease).[48] Of these the most important was psora, described as being related to any itching diseases of the skin and was claimed to be the foundation of many further disease conditions. Hahnemann believed it to be the cause of such diseases as epilepsy, cancer, jaundice, deafness, and cataracts.[49] Since Hahnemann's time, other miasms have been proposed, some replacing illnesses previously attributed to the psora, including tuberculosis and cancer miasms.[45]
Homeopathy achieved its greatest popularity in the 19th century. It was introduced to the United States in 1825 by Hans Birch Gram, a student of Hahnemann.[50] The first homeopathic school in the United States opened in 1835 and the American Institute of Homeopathy was established in 1844. Throughout the 19th century, dozens of homeopathic institutions appeared in Europe and the United States,[51] and by 1900, there were 22 homeopathic colleges and 15,000 practitioners in the United States.[52]
Because medical practice of the time relied on treatments which were often ineffective and harmful, patients of homeopaths often had better outcomes than those being treated by medical practitioners.[53] Though ineffective, homeopathic preparations are rarely detrimental, thus users are less likely to be harmed by the treatment that is supposed to be helping them.[42] The relative success of homeopathy in the 19th century may have led to the abandonment of the ineffective and harmful treatments of bloodletting and purging and begun the move towards more effective, science-based medicine.[54] One reason for the growing popularity of homeopathy was its apparent success in treating people suffering from infectious disease epidemics.[55] During 19th-century epidemics of diseases such as cholera, death rates in homeopathic hospitals were often lower than in conventional hospitals, where the treatments used at the time were often harmful and did little or nothing to combat the diseases.[56]
Even during its rise in popularity, homeopathy was criticized by scientists and physicians. Sir John Forbes, physician to Queen Victoria, said in 1843 that the extremely small doses of homeopathy were regularly derided as useless and considered it "an outrage to human reason".[57] James Young Simpson said in 1853 of the highly diluted drugs: "No poison, however strong or powerful, the billionth or decillionth of which would in the least degree affect a man or harm a fly."[58] Nineteenth-century American physician and author Oliver Wendell Holmes was also a vocal critic of homeopathy and published an essay entitled Homœopathy and Its Kindred Delusions (1842).[36] The members of the French Homeopathic Society observed in 1867 that some leading homeopaths of Europe not only were abandoning the practice of administering infinitesimal doses but were also no longer defending it.[59] The last school in the United States exclusively teaching homeopathy closed in 1920.[42]
According to academics Paul U. Unschuld [de] and Edzard Ernst, the Nazi regime in Germany was fond of homeopathy, and spent large sums of money on researching its mechanisms, but without gaining a positive result.[60] Unschuld also states that homeopathy never subsequently took root in the United States, but remained more deeply established in European thinking.[61] In the United States, the Food, Drug, and Cosmetic Act of 1938 (sponsored by Royal Copeland, a Senator from New York and homeopathic physician) recognized homeopathic preparations as drugs. In the 1950s, there were only 75 solely homeopathic practitioners in the U.S.[62] By the mid to late 1970s, homeopathy made a significant comeback and the sales of some homeopathic companies increased tenfold.[63]
Some homeopaths credit the revival to Greek homeopath George Vithoulkas, who conducted a "great deal of research to update the scenarios and refine the theories and practice of homeopathy" in the 1970s,[64][65] but Ernst and Simon Singh consider it to be linked to the rise of the New Age movement.[29] Bruce Hood has argued that the increased popularity of homeopathy in recent times may be due to the comparatively long consultations practitioners are willing to give their patients, and to a preference for "natural" products, which people think are the basis of homeopathic preparations.[66]
