Clinical trial, with positive findings,  on 36 patients at a homeopathy clinic in Australia. 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 one week’s  treatment, the patients in the homeopathy group reported improved  feeling of wellbeing compared to those in the placebo group.
