Other meanings of Homeopathy
Alternative Medicine
Homeopathy is a system of alternative medicine founded in 1796 by the German physician Samuel Hahnemann, based on the principle that a substance causing symptoms in a healthy person can, in highly diluted form, treat similar symptoms in a sick person. Practitioners select remedies by matching the patient's total symptom picture to the "proving" of a substance, and they prepare remedies through serial dilution and succussion, often to the point where no molecules of the original substance remain. Homeopathy is widely regarded as scientifically implausible and lacks robust evidence of efficacy beyond placebo, yet it remains popular worldwide and is integrated into some national health systems.
Homeopathy rests on two core principles: the law of similars (like cures like) and the minimum dose. Hahnemann's provings—systematic self-experiments on healthy volunteers—catalogued the symptoms produced by many substances, and these became the basis for remedy selection. Remedies are prepared by serial dilution (typically 1:10 or 1:100) with vigorous shaking, called succussion, at each step. Potencies are denoted by scales such as C (centesimal) or X (decimal); a 30C dilution is 10-60, far beyond Avogadro's number, meaning no original molecules remain. Practitioners often prescribe based on constitutional type and individual symptom details, not just the disease label.
Systematic reviews and meta-analyses consistently find that homeopathic remedies perform no better than placebo for most conditions. A 2015 Australian government review of 57 systematic reviews concluded that no condition had reliable evidence that homeopathy was effective beyond placebo. The Swiss Federal Health Office reached a similar conclusion in 2011, recommending that homeopathy not be covered by basic health insurance. Proponents argue that some trials show positive effects, but these are often small, poorly controlled, or subject to publication bias. The plausibility of homeopathy is also challenged by basic physics and chemistry, as no known mechanism explains how a remedy could retain biological activity after extreme dilution.
Hahnemann's ideas gained rapid popularity in 19th-century Europe and the United States, partly as a reaction to the harsh practices of conventional medicine, such as bloodletting and mercury purging. Homeopathic hospitals and medical schools proliferated, and notable figures like James Tyler Kent and Constantine Hering expanded the materia medica. The 20th century saw a decline in the West, but homeopathy experienced a revival in the 1970s with the counterculture movement. Today it is widely used in India, where it is recognized as one of the national systems of medicine, and in parts of Europe, Latin America, and Asia. The global market for homeopathic products was estimated at several billion dollars annually.
Beyond the familiar remedies like Arnica and Oscillococcinum, homeopathy has produced some unusual and controversial practices. Isopathy uses the same disease product (e.g., pus or diseased tissue) as a remedy, while nosodes are made from pathological specimens. Homeopathic immunization (homeoprophylaxis) has been promoted as an alternative to vaccines, a practice strongly criticized by public health authorities. The Bach flower remedies, though not strictly homeopathic, share a similar dilution philosophy. Some homeopaths use radionics or electroacupuncture to diagnose, which lack scientific validation. The Hahnemannian method of single-remedy prescribing contrasts with complex homeopathy, which combines multiple remedies in one product.
Homeopathy remains one of the most debated forms of alternative medicine, with a stark divide between its long tradition and the lack of scientific support for its core claims.
