Abrogation of facial seborrhoeic dermatitis with homoeopathic high dilutions of tobacco: a new visible model for Benveniste's theory of 'Memory of water'.

The author describes the activity of homoeopathic high dilutions of tobacco to treat his familial facial seborrhoeic dermatitis induced by the hapten nicotine. A double-blind experiment against placebo and several treatments with continuous and single intakes of tobacco high dilutions led after a break to a late abrogation of dermatitis simulating a desensitization. These observations provide a new possible explanation for the placebo effect and facial seborrhoeic dermatitis is proposed as a new visible model for Benveniste's theory of 'Memory of water'.
