This study investigated the anti-fibrotic and antioxidant effects of Paeonia Radix Alba water extract (PR) on thioacetamide (TAA)-induced liver fibrosis in a mouse model and its underlying mechanisms. Liver fibrosis was induced by intraperitoneal injection of TAA (three times a week) for 8 weeks. Furthermore, silymarin (50 mg/kg body weight) and PR (200 mg/kg body weight) were administered for 8 weeks. PR treatment downregulated aspartate aminotransferase (AST), alanine aminotransferase (ALT), ammonia, and myeloperoxidase levels. Moreover, PR treatment downregulated NOX2 and p47phox and upregulated antioxidant enzymes by activating the Nrf2/Keap1 signaling pathway. Furthermore, PR inhibited the factors associated with fibrosis, such as α-SMA and collagen I. AMPK/SIRT1 was upregulated by PR treatment. Overall, these results suggest that PR attenuates liver fibrosis by regulating the Nrf2/Keap1 and AMPK/SIRT1/ NF-κB signaling pathways through the inhibition of oxidative stress. Hence, PR has potential as a remedy for preventing and treating liver fibrosis.
