Dual protective effect of ginger and rosemary extracts against CCl 4 -induced hepatotoxicity in rats

Abstract

The present study aimed to investigate the protective effect of aqueous extracts of ginger (GE) and rosemary (RE), both individually and in combination, on carbon tetrachloride (CCl₄)-induced liver injury in adult male rats. CCl₄ induced significant increase in liver enzymes, bilirubin, triglycerides, and total cholesterol while total protein, albumin, and globulin were significantly decreased. Also, the activity of cytochrome P₄₅₀ (CYP) and oxidative stress markers were found to be elevated with a concomitant decrease in the activity of antioxidant enzymes in hepatic tissue. Supplementation with extracts of ginger or rosemary effectively relieved most of the CCl₄-induced alterations when administered singly. The joint therapy of the two extracts was more effective. The histological investigation strongly confirmed the highly protective effect of the two plant extracts in the hepatocytes. These findings suggest that rosemary and ginger extracts are effective in improving both the function and structure of the hepatocytes through their potent antioxidant effect and point out to the possibility of using a combination of both as an adjunct therapy in liver diseases.
