Brain Injury

Clinical trial, with positive findings, on 50 patients with mild traumatic brain injury and treated at a university medical school in the USA. 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 4 months of treatment, the patients receiving homeopathy showed more improvement on certain functional brain tests than the patients receiving placebo.

Allergic Asthma

Clinical trial, with positive findings, on 217 patients with bronchitis who were treated at doctors’ practices in Germany. Approximately half of the patients were randomly allocated to receive a combination of homeopathic medicine called Bronchiselect, and the others received a dummy pill (placebo); they were not told which treatment group they were in. After 3 weeks of treatment, the patients receiving homeopathy had fewer days of coughing than the patients receiving placebo.

Allergic Skin Reaction

Clinical trial, with positive findings, conducted at a university health clinic in South Africa on 30 adult subjects with an allergy to cats. Half of the subjects were randomly allocated to receive a homeopathic combination of cat saliva and histamine; the other half received a dummy medicine (placebo). They did not know which treatment group they were in. After 4 weeks, the subjects who received the homeopathic medicine had a lesser degree of inflammation (wheal) after a skin-prick test than those who received placebo.
