Efficacy and potential pharmacological mechanism of Astragalus-Salvia miltiorrhiza combination in diabetic nephropathy: integrating meta-analysis, network pharmacology, molecular docking, and experimental validation

Conclusion: Through rigorous experimental validation, our study demonstrates AS's significant clinical efficacy in managing DN.
