Homeopathy: how it works and what the research says about it

Homeopathy: how the consultation is conducted, what the dilutions are and what research and European scientific institutions say about their effectiveness..

Homeopathy is a system devised by Samuel Hahnemann at the end of the 18th century and is based on two principles: that a substance that causes certain symptoms in a healthy person should eliminate those same symptoms in a sick person, and that with repeated dilutions the effect should become stronger, not weaker. Since this is an area where people's expectations and the findings of science diverge more than anywhere else on this page, it's best to write it out in the open and at the beginning, not hidden in a footnote. Homeopathy is based on dilution of substances and individual consultation. This page provides an overview of how the consultation takes place and what the research finds about its effectiveness. The consultation is long and detailed, often an hour or more. Scientific institutions do not confirm effects over placebo. Never stop the prescribed treatment without consulting your doctor. What research says about effectiveness. This is the most important part of the page, so we list it first. Extensive reviews of research and statements from prominent scientific institutions — including the Australian National Health and Medical Research Council, the British Parliamentary Committee on Science and Technology, and the Association of European Academies of Science EASAC — concluded that there is no reliable evidence that homeopathy is more effective than placebo for any medical condition. The reason given by the profession is simple: with high dilutions, such as are common in homeopathy, there is usually not a single molecule of the starting substance left in the preparation. As a result, several European countries withdrew homeopathy from public funding. This is not to say that people do not report improvement after a visit — they often do — but that, according to current evidence, it is not attributable to the preparation itself. How does the consultation work?. A homeopathic consultation is unusually long compared to most treatments: the first visit can last an hour to two. The homeopath asks much more broadly than just the reason for the visit — about sleep, appetite, temperature preferences, mood, stress responses, life circumstances and past illnesses. Many people point to this as the most valuable part of the experience: rarely does someone take so much time and listen so carefully. Based on this, the homeopath chooses a preparation that should correspond to the whole picture, not just to a single sign; therefore, two people with the same problem often receive different preparations. Preparations are usually in the form of beads or drops with a label such as C30 or D12, which indicates the degree of dilution. This is followed by a follow-up visit in a few weeks to assess the response. Where the risk is. Homeopathic preparations themselves are chemically practically inert at high dilutions and as such rarely cause direct harm. The main risk is elsewhere and it is serious: that someone postpones or abandons the treatment they need because of homeopathy. This can be dangerous for serious conditions — infections, diabetes, cancer, heart disease, mental distress. It is especially worth noting that homeopathic preparations are not and cannot be a substitute for vaccination; so-called homeopathic alternatives to vaccination do not provide protection. If you are considering homeopathy, think of it as something that can exist alongside conventional medical care, but never in place of it. Inform your doctor and do not change the prescribed therapy on your own. A homeopath who advises against medicines, vaccinations or visits to the doctor is acting dangerously. Why people still report improvement. This question is more interesting than it seems, and the answer is not that people are making things up. First, most of the problems that bring people to a homeopath — colds, mild indigestion, periods of fatigue — go away on their own, no matter what we do in between; if the preparation is taken just before this, the improvement is attributed to it. Second, a long and attentive consultation is in itself an experience that people rarely get elsewhere; the feeling that someone is listening to you for an hour and a half definitely affects your well-being. Third, the placebo effect is a real and measurable phenomenon that can significantly change the experience of symptoms, even if it does not change the course of the disease. None of this is a reason to scoff — but it is a reason that the improvement does not prove that the preparation works, and cannot be counted on in a serious condition. How to choose a contractor if you decide on one. If, despite the above, you decide to try homeopathy, the most important criterion is the practitioner's attitude towards conventional medicine. A good sign is a homeopath with medical training who makes it clear that his work does not replace a doctor, who asks what medicines you are taking and who refers you further in case of more serious symptoms. Anyone who advises against prescribed therapy or vaccination, promises to cure a disease or advises against diagnostics is a bad sign. Also check his education and how long he has been working. Pay attention to the price of the preparations and whether the contractor commits you to long programs. On Zeen Connect, profiles show education and work style so you can compare contractors — and with this practice, this check should be done more thoroughly than any other.
