Scientific evidence and homeopathy.

There are currently no good quality studies which show homeopathy really works over and above the placebo effect. There are many small studies which show it works, although they tend to be poorly designed and conducted by homeopaths themselves. Larger studies that are well designed and conducted scientifically do not show that homeopathy works at all. The evidence for homeopathy seems to be inversely proportional to the quality of the studies done: the better the study the less chance of a positive finding.
