Abstract
Major depressive disorder (MDD) occurs more often in women than that in men due to various complex causes. This study aimed to evaluate the effectiveness and safety of Yukwool-tang (YWT) for MDD in women. A total of 72 patients diagnosed with MDD and Korean version of the Hamilton Depression Rating Scale (K-HDRS) ≥ 14 points were randomly assigned to the YWT or placebo group, and 1 bottle (30 mg) of No-S solution and placebo was administered to the YWT and placebo groups, respectively, orally thrice a day for 8 weeks. The evaluation was conducted through K-HDRS, Korean version of the Beck Depression Inventory (BDI-K), Korean version of the Beck Hopelessness Scale (K-BHS), Korean version of the Insomnia Severity Index (ISI-K), State-Trait Anxiety Inventory (STAI-K), EuroQol-5 dimension (EQ-5D), and Pattern Identifications Tool for Depression (PITD). Fifty patients completed the trial. In the YWT group, the K-HDRS, BDI-K, K-BHS, ISI-K, STAI-K, and EQ-5D scores changed significantly at the 8th week, but there were no significant differences with the placebo. In subgroup analysis, the K-BHS score with an initial K-HDRS score < 18 points was significantly decreased compared to placebo at the 12th week (P < .05). In the YWT group, the ratio of Stagnation of Liver Gi () was the highest, but Dual Deficiency of the Heart and Spleen () became the highest after administration, which was also the highest in the placebo group both before and after administration. YWT improved depression and accompanying symptoms in women with MDD, although it was not significant compared to placebo, and it might be effective in improving the degree of hopelessness. The effect of YWT will become relatively clear through further research that can overcome certain limitations.
