Schistosomiasis remains to be the most common fibrotic disease resulting from inflammation and deposition of scar tissue around trapped parasitic eggs in the liver. Though chemotherapy eradicates matured worms efficiently and prevents the accumulation of schistosome eggs, fewer effective drugs are directed to reverse the present hepatic fibrosis. Therefore, treatment targeting hepatic fibrosis associated with schistosomiasis remains a challenging proposition.The present study was designed to investigate the potential complementary schistosomicidal and hepatoprotective activities of the methanol extract of Capparis spinosa L. (C. spinosa) with or without praziquantel (PZQ) and compare results with silymarin (Milk thistle), a known hepatoprotective and antifibrotic agent, on induced liver fibrosis by experimental Schistosoma mansoni (S. mansoni) infection. Total polyphenols in the extract were determined using colorimetric assay.C. spinosa L. caused a partial decrease in worm burden; a statistically significant reduction in hepatic and intestinal tissue egg load, what was associated histopathologically with decreasing in both the number and diameter of granulomas, as well as restoring serum aminotransferases (AST & ALT), alkaline phosphatase (ALP) and improving liver albumin synthesis.
