10% of the UK population regularly use homeopathic medicines and the reason they do is simple: they have found that homeopathic medicines provide safe and effective treatment for a range of conditions. And there is a growing evidence base to support this.
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.
So there is positive evidence, and more positive than negative. Team that fact alongside positive patient reported outcomes of thousands of patents at homeopathic hospitals, a form of evidence which NICE has highlighted as a key form of evidence that should be considered besides RCTs. You can only say that there is evidence homeopathy works.
