The evidence for homeopathy There is a growing body of clinical evidence to show that homeopathy has a positive effect.
Randomised controlled trials The widely accepted method of proving whether or not a medical intervention works is called a randomised controlled trial (RCT). One group of patients, the control group, receive placebo (a “dummy” pill) or standard treatment, and another group of patients receive the medicine being tested. The trial becomes double-blinded when neither the patient nor the practitioner knows which treatment the patient is getting. RCTs are often referred to as the “gold standard” of clinical research.
A total of 142 RCTs in homeopathy have been published in good quality scientific journals: positive effects have been reported in 63 (44% of the total) and negative findings have been reported in 11 (8%), while 68 (48%) have not been conclusively positive or negative.
Systematic reviews The most solid evidence for a treatment comes from reviewing more than one RCT. This is known as a systematic review. Four out of five major systematic reviews of RCTs in homeopathy have concluded (with certain caveats) that homeopathy has an effect greater than placebo Läs mer
