The term "homeopathy" is derived from the Greek words homeo (similar) and pathos (suffering or disease). The first basic principles of homeopathy were formulated by German physician Samuel Hahnemann in the late 1700's. The practice of homeopathy is based on the belief that disease symptoms can be cured by small doses of substances which produce similar symptoms in healthy people.

Central to all homeopathy is the determination of the effect of substances on healthy volunteers and the use of the developed "drug picture" by the consumer and/or trained health care practitioners according to the homeopathic principle of similia similibus curentur - Let Likes be cured by Likes. Homoeopathic drugs, by international convention, are designated by their Latin names.

The potencies of homeopathic drugs are specified in terms of dilution, i.e., 1X (1/10 dilution), 2X (1/100 dilution), etc. Also called homeopathic attenuation, the potency refers to the number of times the original substance has been diluted and succussed according to a method described in homeopathic pharmacopoeia.

Homeopathic potency is written as a number associated with one of the following letters or combinations of letters: X, D, C, CH, K, CK, M, MK, LM or Q (see below).

So, in summary in a product containing Sepia 4X, the substance was diluted with nine parts dilutant and repeated four times (1/10000 dilution), whereas for preparing Sepia 4CH, the substance was diluted with 99 parts dilutant and repeated 4 times (1/100000000 dilution).

Homeopathy, Phytotherapy, Gemmotherapy, Oligo-elements and Schüessler Tissue Salts are modalities used in traditional medicine. Homeopathic uses are based on the Materia Medica and are not supported by clinical trials. These therapies are not substitutions for standard medical care.
