Hepatoprotective activity of Emblica officinalis and Chyavanaprash.

Hepatoprotective activity of Emblica officinalis (EO) and Chyavanaprash (CHY) extracts were studied using carbon tetrachloride (CCl(4)) induced liver injury model in rats. EO and CHY extracts were found to inhibit the hepatotoxicity produced by acute and chronic CCl(4) administration as seen from the decreased levels of serum and liver lipid peroxides (LPO), glutamate-pyruvate transaminase (GPT), and alkaline phosphatase (ALP). Chronic CCl(4) administration was also found to produce liver fibrosis as seen from the increased levels of collagen-hydroxyproline and pathological analysis. EO and CHY extracts were found to reduce these elevated levels significantly, indicating that the extract could inhibit the induction of fibrosis in rats.
