A comparison of analysis in evaluating the hepatoprotective action of ethanolic extract of M. azedarach (MAE) and P. longum (PLE) with their combination biherbal extract (BHE) against carbon tetrachloride (CCl4) induced hepatic damage is reported in albino rats. There was a marked elevation of serum marker enzyme levels in CCl4 treated rats, which were restored towards normalization in the drug (MAE and/or PLE:50 mg/kg body weight po, once daily for 14 days) treated animals. The biochemical parameters like total protein, total bilirubin, total cholesterol, triglycerides, and urea were also restored towards normal levels. The combined BHE showed more significant reduction of the enzymes than MAE or PLE against CCl4 induced hepatotoxicity. The results strongly indicate that BHE has more potent hepatoprotective action than MAE or PLE individually against CCl4 induced hepatic damage in rats. Among these extracts, BHE showed similar hepatoprotective action to silymarin, which was the positive control in this study.
