BMC complementary medicine and therapies (2025) · Meta analysis · n=3545
According to the findings of this meta-analysis silymarin administration showed a significant reduction in AST (SMD [95% CI]: - 0.670 [- 0.931, - 0.408], p-value = 0.000), and ALT (SMD [95% CI]: - 0.912 [- 1.177, - 0.646], p-value = 0.000) levels.
Meta-analysis shows modest SBP reduction of ~4 mmHg and DBP reduction of ~1.4 mmHg. Effect size is relatively small compared to pharmaceutical interventions. Studies primarily used aged garlic extract forms.
Based on multiple meta-analyses showing significant ALT/AST reduction. Effect size modest (SMD -0.67 to -0.9). Effectiveness assumes standardized 80% silymarin extract. Lower bioavailability forms may require higher doses.
