Can homeopaths detect homeopathic medicines by dowsing? A randomized double-blind placebo-controlled trial

摘要

Dowsing is a method of problem-solving that uses a motor automatism, amplified through a pendulum or similar device. In a homeopathic context, it is used as an aid to prescribing and as a tool to identify miasm or toxin load. A randomized double-blind trial was conducted to determine whether six dowsing homeopaths were able to distinguish between Bryonia in a 12c potency and placebo by use of dowsing alone.The homeopathic medicine Bryonia was correctly identified in 48.1% of bottle pairs (n=156; 95% confidence interval 40.2%, 56.0%; P=0.689).These results, wholly negative, add to doubts whether dowsing in this context can yield objective information.
