Clinical trial, at a skin clinic in the  USA, with positive findings in a total of 29 patients with seborrhoeic  dermatitis (facial eczema with dandruff). Approximately half of the  patients were randomly allocated to receive homeopathic medicine and the  others received dummy medicine (placebo); they were not told which  treatment group they were in. After a period of 10 weeks’ treatment, the  group that received the homeopathic medicine reported more improvement  in skin symptoms than the group that received placebo.
