Many families in Bangladesh have a homeopath they trust, a small bottle of sweet white pills in a drawer, or a relative who swears by a particular remedy. Yet if you ask what homeopathy actually is, the answers are often vague. This article sets out the basic ideas in plain language: where homeopathy came from, the principles it rests on, how a consultation works and how the system is regulated in our part of the world.
Where the name and the idea come from
Homeopathy was developed by Samuel Hahnemann, a German physician born in Meissen, Saxony, in 1755. He qualified in medicine at the University of Erlangen in 1779, but he grew unhappy with the harsh treatments of his day, such as heavy bloodletting and large doses of toxic substances. For some years he gave up regular practice and earned his living translating medical books.
While translating a textbook by the Scottish physician William Cullen in 1790, Hahnemann read an explanation of why cinchona bark (the source of quinine) worked against malaria. He was not convinced, so he took the bark himself while healthy and recorded that he developed symptoms resembling the fever it was used to treat. That experience set him thinking, and in 1796 he published an essay proposing a new principle for finding out what medicines can do.
The word he later coined, homeopathy, comes from two Greek words: homoios, meaning "similar", and pathos, meaning "suffering". The name itself tells you the central idea.
The core principles
Like cures like
The first principle is often summed up in the Latin phrase similia similibus curentur, "let like be cured by like". The idea is that a substance which can produce a certain pattern of symptoms in a healthy person may be used, in a specially prepared form, for a sick person showing a similar pattern. A familiar illustration is the onion: cutting one makes the eyes water and the nose run, and a remedy prepared from red onion, Allium cepa, is traditionally considered by homeopaths for colds with those features.
Provings
To know what a substance can produce, Hahnemann and his students gave it to healthy volunteers and carefully noted every change they felt. These experiments are called provings. Their records, collected over two centuries, make up the homeopathic materia medica, the reference books a practitioner studies.
Individualisation
Homeopathy treats the person rather than only the name of the illness. Two people with the same diagnosis may receive different remedies because their overall pattern differs. One person with a headache may feel worse in the sun, want to be left alone and crave cold water. Another may feel better from pressure and fresh air and feel weepy. A homeopath would see these as different pictures.
The minimum dose
Hahnemann found that ordinary doses could aggravate symptoms, so he reduced them step by step. He taught that the smallest dose able to produce a gentle response is the right one, and that a remedy should not be repeated more often than needed.
The vital force
In his main book, the Organon, first published in 1810, Hahnemann described a "vital force", an energy that keeps the living body in balance. In his view, illness is first a disturbance of this force, and the symptoms we notice are its outward expression. The remedy, chosen to match those symptoms, was meant to prompt the body's own effort to restore balance. This is a philosophical concept from the early nineteenth century. It is central to how classical homeopaths think about health, but it is not something that modern biology measures or recognises, and it helps to know that when you read about it.
Potencies: what the numbers on the bottle mean
Homeopathic medicines are made from plant, mineral and animal sources. Common examples include Arnica (a mountain flower), Belladonna (deadly nightshade), Natrum muriaticum (ordinary table salt) and Sulphur. The starting material is diluted in stages, and at each stage the mixture is shaken vigorously, a step called succussion. Homeopaths call the whole process potentisation.
- X or D potencies are diluted one part in ten at each step.
- C potencies are diluted one part in a hundred at each step. A "30C" has been through this thirty times.
- LM or Q potencies use a much larger dilution at each step and were described in the sixth edition of the Organon.
The finished liquid is usually dropped onto small sugar globules, which is why most patients know homeopathy as little white pills. Many common potencies are diluted so far that, by ordinary chemistry, none of the original molecules is likely to remain. This is the main reason many scientists doubt that the medicines can act, and it is also why homeopaths have long tried to explain their effects in other ways. It is a genuine point of debate, and patients deserve to know about it.
How a consultation works
A first homeopathic consultation is usually long. Besides the main complaint, the practitioner asks about sleep, appetite, thirst, food likes and dislikes, reactions to heat, cold and weather, energy through the day, mood, and past illnesses in the family. Small details that seem unimportant, such as which side of the body is affected or what time of day things get worse, can matter a great deal in this system.
The homeopath then compares the picture with the materia medica, often using a repertory, an index that lists symptoms and the remedies associated with them. One remedy is usually chosen, with instructions on how often to take it. Follow-up visits check how things have changed and whether the prescription should be continued, adjusted or stopped.
A responsible practitioner will also recognise when a problem needs urgent medical attention, tests or a specialist, and will tell you so. Homeopathy should not be used in place of emergency care, and you should not stop medicines prescribed by your doctor without talking to that doctor first.
Who uses it and how it is regulated
Homeopathy is practised in many countries, from Germany, where it began, to France, the United Kingdom and the Americas. It is especially widespread in South Asia. In India it is one of the officially recognised systems of medicine under the Ministry of AYUSH. Its education and practice are regulated by the National Commission for Homoeopathy, which was constituted in July 2021 and replaced the Central Council of Homoeopathy that had been set up under a 1973 Act.
In Bangladesh, practice was long governed by the Bangladesh Homoeopathic Practitioners Ordinance of 1983, with a Homoeopathic Board responsible for registering practitioners. Qualified practitioners hold either a diploma (DHMS) or a bachelor's degree (BHMS); the Government Homoeopathic Degree College in Dhaka, established in 1989, offers the BHMS. In November 2023 Parliament passed the Bangladesh Homeopathic Medical Education Bill, which repeals the 1983 Ordinance and replaces the board with a council to oversee education, registration and standards. If you are choosing a homeopath, it is reasonable to ask about their qualification and registration.
What the evidence says
People who use homeopathy often report that they feel better, and many value the time and attention of the consultation. Scientific opinion on whether the remedies themselves have a specific effect is divided. Large reviews, such as the 2015 report by Australia's National Health and Medical Research Council, concluded that there was no reliable evidence that homeopathy is effective for any health condition beyond a placebo effect. Homeopathy researchers have contested that report and its methods, and research continues on both sides.
The honest summary is that homeopathy is a distinct, two-hundred-year-old system with its own principles and a large following, and that its effectiveness remains a subject of active debate. If you are curious about it, the best approach is to see a qualified, registered practitioner, keep your regular doctor informed, and ask questions freely. A good homeopath will welcome them.
