    Abstract:
    Alternative medicines are being increasingly used and investigated in the management of a variety of disorders. Hepatitis is a common indication for the use of alternative therapies but evidence for the efficacy of many compounds is lacking. We have utilized a well-defined model of liver injury to study the efficacy of three herbal products designed to assist in the management of liver disease. Mice were exposed to carbon tetrachloride (CCL4) given intragastrically after they had been pretreated for five days with either saline or one of four doses of silymarin extract or CH100 (a Chinese herbal medicine comprising of 19 herbs) or one of two doses of CH101 (a Chinese herbal preparation designed to reduce fibrosis). Animals were sacrificed 24 hours after receiving CCL4. Liver enzymes and hepatic histology formed the basis for evaluating efficacy of the treatments. Each of the alternative medicines reduced the alanine amino transferase (ALT) elevation demonstrated after CCL4 injection. The high dose CH100 regimen was most effective in protecting against injury and this was confirmed with hepatic histology. Other doses of CH100, CH101 and silymarin were not shown to provide protection against the histological damage. In conclusion, Silymarin, CH100 and CH101 are able to reduce ALT elevation in animals exposed to CCL4. High dose CH100 provides protection from hepatocyte necrosis in this model. The data add to our understanding of the capacity some herbal medicines have to modify the reaction of the liver to a variety of insults and suggest the value of studying these agents further in human liver diseases.
