STEVIA

The effect of stevia on liver cirrhosis has not been previously investigated. In the present study, the antioxidant and anti inflammatory properties of stevia leaves were studied in male Wistar rats with carbon tetrachloride- (CCl4-) induced acute and chronic liver damage. Acute and chronic liver damage induced oxidative stress, necrosis, and cholestasis, which were significantly ameliorated by stevia.
