Medicinal herbs have been used for centuries in an attempt to overcome hepatic dysfunctions emanating from ingestion of hepatotoxic substances. However, the vast majority of information concerning their use is anecdotal. Well-performed animal studies would lend credence to the concept that some medicinal herbs may prevent or, at least ameliorate, hepatic dysfunction arising from drug-induced ...
