Clinical trial, with positive findings, on 30 cancer patients with stomatitis (serious mouth inflammation) at a Children’s Medical Centre in Israel. Approximately half of the patients were randomly allocated to receive a homeopathic medicine called Traumeeel; the others received dummy medicine (placebo). They did not know which treatment group they were in. After 2 weeks, the patients who received the homeopathic medicine had less severe stomatitis symptoms than those who received placebo.
