Modulatory Effect of Methanol Extract of Piper guineense in CCl4-Induced Hepatotoxicity in Male Rats

This study seeks to investigate the possible protective role of the methanol extract of Piper guineense seeds against CCl₄-induced hepatotoxicity in an animal model. Hepatotoxicity was induced by administering oral doses of CCl₄ (1.2 g/kg bw) three times a week for three weeks. Group 1 (Control) and Group 2 (CCl₄) were left untreated; Piper guineense (PG; 400 mg/kg bw) was administered to Group...
