Effect of Korean Red Ginseng as an adjuvant treatment for women with residual symptoms of major depression

초록

IntroductionAround 20% of patients with major depression experience residual symptoms. Ginseng has shown potential antidepressant effects in some animal studies and in patients with stress-related somatic symptoms. Therefore, we investigated the effectiveness and tolerability of Korean Red Ginseng adjuvant treatment in patients with residual symptoms of major depression. MethodsIn this eight-week prospective study, 35 female outpatients aging from 18 to 65 years (45.19.5), who were remitted from major depression with residual symptoms, were given Korean Red Ginseng at doses of 3g/day. The Depression Residual Symptom Scale (DRSS) and Montgomery-angstrom sberg Depression Rating Scale (MADRS) were administrated to evaluate depressive symptoms. The general severity of symptoms was assessed by a clinician using the Clinical Global Impressions Scale for Severity (CGI-S). The Depression and Somatic Symptom Scale (DSSS) was also used to evaluate somatic symptoms in the subjects. This trial is registered at Clinical.gov, number NCT01496248. ResultsSubjects reported significant decrease in depressive symptoms on the DRSS (P<0.05) and MADRS (P<0.01) decreased significantly over the eight-week period. The scores on the CGI-S, an objective measurement of symptoms, showed significant improvement in the severity of illness (P<0.001). Somatic symptoms on the DSSS also attenuated significantly during the study period (P<0.05). DiscussionThese results suggest that Korean Red Ginseng is efficacious as an adjuvant treatment for patients experiencing residual symptoms of major depression. Future placebo-controlled research is required to confirm our results.
