Abstract

An homoeopathic pathogenic trial (HPT, proving) was carried out using a double-blind, placebo-controlled crossover method. The name of the medicine was also unknown to the volunteers. A number of subjects withdrew at the last minute, leading to an unbalanced randomisation. A strong period effect was observed, which makes results difficult to interpret. Most subjects were able to guess correctly which treatment was active and which placebo.
