In a multicenter, placebo-controlled double-blind trial, the effect on depression (ICD 10 F 32.1) of treatment with an innovative highly concentrated hypericum preparation was investigated. The study contained 97 outpatients who received 100 to 120 mg of the hypericum extract bid. The course of the illness was assessed with the Hamilton Depression Scale (HAMD), the von Zerssen Depressivity Scale (D-S) and the Clinical Global Impression Scale (CGIS). Treatment resulted in an appreciable improvement in the symptoms of depression, and the 70% response rate (n = 43), corresponded to that of chemical antidepressants. The preparation also showed an anxiolytic effect. The substance was extremely well tolerated, and no side-effects were reported by any of the patients.
