Protective effect of <i>Salvia miltiorrhiza</i> in rheumatoid arthritis patients: A randomized, single-blind, placebocontrolled trial
Abstract
Purpose: To study the protective effect of Salvia miltiorrhiza (SM) against rheumatoid arthritis (RA) in RA patients.
Methods: Sixty RA patients were divided into two groups: SM (n = 30) and placebo (n =30) groups given SM at a dose of 250 mg/kg (3 capsules/day), and placebo (3 capsule/day), respectively, for 12 weeks. Patient responses based on American College of Rheumatology (ACR), health assessment
questionnaire (HAQ) score, and global assessment of disease (GAD) were recorded. Moreover, Disease Activity Score (DAS) 28, pain score (visual analogue score, VAS), rheumatoid factor (Rh factor), and inflammatory cytokines (markers) were determined.
Results: After 12 weeks of intervention with SM, ACR20 (30 %)/ACR50 patient response (13.3%, i.e., score for swelling and tenderness of joints), was significantly improved. There were considerable reductions in GAD, HAQ, DAS 28, pain score (VAS), and levels of erythrocyte sedimentation rate
(ESR), acute phase reaction protein (CRP), Rh factor (IgM) and inflammatory cytokines (IL-1β, IL-6 and TNF-α), when compared to placebo (p < 0.01). Treatment with SM produced milder adverse effects than treatment with placebo (p < 0.01).
Conclusion: Overall, SM produces better anti-RA effect than placebo by significantly altering ACR patient response, reducing GAD, HAQ, DAS 28 scores, Rh factor, ESR, CRP and inflammatory cytokines in RA patients. However, a large-scale clinical trial is needed before SM can be recommended for combating RA and its related symptoms.
