JUST ONE DROP tells the little-known story of homeopathy: one of the most controversial systems of medicine. Homeopathy often uses minute doses of a highly diluted substance to stimulate the body to heal itself. To many, homeopathy seems implausible. They fear it is purely a placebo effect or worse, a form of deception or quackery. Yet, homeopathy has been around for over 200 years and is used by millions worldwide. The film explores the controversy, reveals the rich history, dispels myths and misconceptions, and asks whether or not homeopathy has been given a fair shake. JUST ONE DROP is not just about homeopathy. This is a film about freedom of choice in healthcare.
