Abstract Background Liver fibrosis is an irreversible liver destruction. Apigenin (API) has different pharmacological properties as anticancer, anti-inflammatory, and antioxidant; however, API hepatoprotective and therapeutic effects are not often studied. This study assesses protective and therapeutic API effects on hepatic injuries produced by thioacetamide (TAA) in rats. Methods Forty-nine rats were sorted into seven groups (7 in each): negative control (G1), positive control (G2, TAA), API group (G3), TAA+API group (G4), TAA+SL group (G5), API+TAA group (G6), and SL+TAA group (G7). API and SL effects on TAA-induced hepatotoxicity were examined by determined body weights, liver weights, complete blood count picture (white blood cells, red blood cells, hemoglobin, hematocrit, and platelets counts), liver function tests (alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, gamma glutamyl transferase, alkaline phosphatase, total proteins, albumin, and globulin), and oxidative stress markers (malonaldehyde, catalase, superoxide dismutase, and reduced glutathione) in serum and liver histological was assessed. Results TAA decreased red blood cells, platelets, hemoglobin content, and hematocrit ( p <0.001) and increased white blood cells count ( p <0.001) versus control. Serum values of alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, gamma glutamyl transferase, alkaline phosphatase, and malondialdehyde significantly elevated ( p <0.001); meanwhile, total protein, albumin, globulin, catalase, superoxide dismutase, and glutathione S transferase decline ( p <0.001) versus negative control. Hepatic structure of TAA group revealed fibrosis and hepatocyte destruction. Therapeutic or protective treating TAA-rats with API or SL ameliorate hematological values, liver functions, oxidative stress, and histological alterations especially therapeutic effects on hematological changes, liver function tests, and oxidative stress markers. Conclusions Apigenin had therapeutic and protective effects on liver fibrosis due to its antioxidant activity with therapeutic better than protective effects.
