This section aims to give you a clear account of the research evidence in homeopathy. Also, see 2-page summary of evidence with full references.

The evidence base

Up to the end of 2014, there have been 189 peer-reviewed papers, with useable data, that reported randomised controlled trials (RCTs) in homeopathy. Of these, 104 papers were placebo-controlled and were eligible for our detailed review programme: this literature represents research in 61 different medical conditions. Of these 104 RCT papers, 43 (41%) reported positive findings, 5 (5%) were negative and 56 (54%) were non-conclusive – see section Randomised controlled trials in homeopathy.

A number of systematic reviews have evaluated the homeopathic research literature.

Non-randomised, non-controlled clinical outcomes studies make a useful contribution to the evidence base.

The Faculty’s contribution

The Faculty is working in tandem with the British Homeopathic Association to develop a strong evidence base in homeopathy. Visit the British Homeopathic Association website for information on its current programme of systematic reviews and meta-analysis.
