Clinical trial, with positive findings, on 90 individuals treated for snoring by an Ear Nose & Throat specialist in the USA. Approximately half of the participants were randomly allocated to receive a homeopathic medicine called Snore Stop, and the others received a dummy pill (placebo); they were not told which treatment group they were in. After 10 days, the partners of those who received the homeopathic medicine reported a greater reduction in snoring than those whose partners received placebo.
