[Homeopathy--the past or a part of future medicine?].

The exact mechanism for the effect of homeopathic remedies is still an enigma. Research shows in vitro effects of homeopathy, as well as differences between the effects of simple dilutions and so called homeopathic potencies. Some of the (relevant) publications are widely disputed. More than 100 controlled clinical trials in humans have been published, but the quality of the majority of the studies is not acceptable. However, some good quality studies do show an effect of homeopathic medicine. We therefore recommend further studies and propose a model for study design. No serious side effects have been reported from homeopathic medicine.
