Homeopathy: another elaborate placebo
This is an interesting BBC Horizon Documentary which examines whether water in Homeopathic “medicine” really has a “memory effect” even if scientifically it would be highly unlikely to contain any molecules of the original substance left behind at extreme dilutions.
The video is 43 minutes long but worth the watch. Nicely done, BBC!
