Efficacy and safety of Lutai Danshen Baishao granules for treating female melasma: A randomized, double-blind, placebo-controlled trial
Abstract
To investigate the potential efficacy and safety of Lutai Danshen Baishao granules (LDBG) for treating female melasma associated with kidney deficiency and blood stasis patterns.
A randomized, double-blind, placebo-controlled trial was conducted at the Third Central Hospital of Tianjin, China from March to December 2023. A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days. Efficacy was assessed through measures such as the total melasma area, reduced melasma area, reduction rate of melasma area, melasma color score, Melasma Area and Severity Index (MASI) score, and traditional Chinese medicine (TCM) symptom score scale. Safety assessments included routine blood and biochemical tests.
Participants in both groups were aged 52–63 years, with no significant differences. After the 2-month intervention, the total melasma area decreased in both groups; however, a greater reduction was observed in the test group [462.50 mm2 (12.81%) vs. 100.00 mm2 (3.11%), P <.001]. Moreover, LDBG treatment significantly reduced the MASI and melasma color scores in the test group (P <.05). The total TCM symptom evaluation score significantly decreased (test group:6.00 vs. placebo group:7.00, P =.001), with significant relief in symptoms such as improvement in dark lips, nails, and waist soreness in the test group, compared with that in the placebo group (P <.05). Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group (P <.05).
LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.
