Placebo:

Dr David Reilly and his team at Glasgow University have conducted four randomised double blind placebo controlled trials, over a period of 18 years, specifically designed to examine the evidence for the hypothesis that any benefits of homeopathy are due to the placebo effect. All four trials involving a total of 252 patients produced similar, positive results demonstrating that homeopathy has an effect greater than placebo and that these results are reproducible.4
