1. Homeopathy is an alternative method of therapy, developed in the 1800s by Samuel Hahnemann. His idea was this: when given in normal (allopathic) dosage, a drug (in the sense of medicament) will produce a constellation of symptoms; however, in a patient whose disease symptoms resemble just this mosaic of symptoms, the same drug (simile principle) would effect a cure when given in a very low dosage (“potentiation”).

2. The body’s self-healing powers were to be properly activated only by minimal doses of the medicinal substance. The homeopath’s task is not to diagnose the causes of morbidity, but to find the drug with a “symptom profile” most closely resembling that of the patient’s illness. This drug is then applied in very high dilution.

3. A direct action or effect on body functions cannot be demonstrated for homeopathic medicines. Therapeutic success is due to the suggestive powers of the homeopath and the expectancy of the patient. When an illness is strongly influenced by emotional (psychic) factors and cannot be treated well by allopathic means, a case can be made in favor of exploiting suggestion as a therapeutic tool. Homeopathy is one of several possible methods of doing so.
