Sources for preparing homeopathic medicines are mainly plants, minerals, some substances of animal origin, tissues, and chemical substances, including poisons.

Usually medicines are taken under the form of small white granules, single powders and drops put under the tongue. In particular cases they can be rubbed into the skin in appropriate places.
In the 4th century BC the Greek healer Hippocrates discovers the availability of two different approaches to the disease – by the “opposite” and by the similar”. Orthodox medicine – “allopathy” cures o n the principle of the opposite, while the homeopathy – o n the similar.
“Proving” is a term used in the homeopathic pharmacy. The potentized homeopathic product is accepted as a medicine after testing o n healthy volunteers, never o n animals. It is given in repeated doses to a group of people until appearance of symptoms. A detailed record of the sensations of every prover is made and this information is the picture which the remedy cures. This picture is recorded in the homeopathic Materia Medica, and in the homeopathic Pharmacopoeia an article is written about the source, obtaining and proving.

Homeopathic remedies are applied for first aid and for treatment of chronic diseases. When giving first aid, the physical symptoms in human are the nearest possible to the information of the physical symptoms of medicine. When curing chronic complaints the most appropriate medicine must be found, taking into consideration the totality of symptoms in the ill person /on mental, emotional and physical level/.

„All medicines without exception cure those diseases whose symptoms most closely resemble their own, and leave none of them uncured.” S. Hahnemann, Organon of Medicine – sixth edition.

Homeopathic medicines have a powerful effect o n the immune system of the organism. The first step in preparing a homeopathic medicine is to make a tincture /infusion/. The second step is according to the method of S. Hahnemann – multiple potentization /dynamization, succussion/ of an alcohol solution, in which o ne drop of the tincture is put. Different quantity of alcohol in which a single drop of tincture is diluted and dynamized, determines different types of potencies /dilutions/ of the homeopathic medicines.
C or CH /H - after Hahnemann/ potency is called also centesimal dilution: 1+99=100, or o ne drop of the tincture is mixed with ninety nine drops of alcohol and dynamization follows.
D or X potency is a decimal dilution: 1 + 9 = 10 or o ne drop of tincture is mixed with nine drops of alcohol and dynamization follows.
LM potency is the so called soft potency and represents dilution 1:50 000.
K potency is prepared after the Korsakov’s method, in which the dilutions are effected as in the C potency but at all stages is used o nly o ne vessel, while with the other dilutions the vessels are for single use.

There are other types of dilutions but in practice the above-mentioned are mainly used.
There are two types of homeopathic medicines: monopreparations – from o ne substance o nly, and combined – from several substances.
