Terminalia bellirica (Gaertn.) Roxb. fruit mitigates CCl4 induced oxidative stress and hepatotoxicity in rats.

Terminalia bellirica (Gaertn.) Roxb. is a medicinal plant used for the treatment of various ailments in the traditional system of medicine like Ayurveda where it has been prescribed as a rejuvenator and general health tonic. The fruit of the plant is one of the components of the age old ayurvedic formulation-'Triphala'. The present study evaluates curative effect of aqueous acetone extract of Terminalia bellirica fruits (AATB) against CCl4 induced oxidative stress and liver damage in an animal model. Two doses of the fruit extract (200mg/kg body weight and 400mg/kg body weight) were investigated for the beneficial effects. At the end of the treatment, liver function markers (ALT, AST, ALP, GGT, LDH, total bilirubin, total protein, albumin, globulin, albumin-globulin ratio) as well as hepatic oxidative stress markers (SOD, CAT, GSH) were evaluated. Treatment with AATB significantly restored the parameters towards normal level as compared to the elevated biochemical markers in the CCl4 treated animals. Reversal to normal tissue architecture was observed in histological evaluation. The results of AATB (400mg/kg) were found comparable with that of standard drug silymarin in all the parameters. The above findings suggest the therapeutic potential of the plant in alleviating hepatic oxidative stress and tissue damage, hence the traditional use of the plant in this regard stands justified.
