A liver is responsible for drug metabolism in a body. 10% of all medicine side effects lead to liver injury. Herb medicine is not an exception to this rule but all Herb medicines do not lead to liver injury absolutely. As for two times of occurrence of the drug induced liver injury during treatment of a CVA patient, we gave him Herb medicines in conjunction with Western medicines and Western medicines alone for each case. We meet with the result that giving the patient Herb medicines in conjunction with Western medicines reduces the duration of decreasing AST, ALT level as compared with giving him Western medicines alone. So we are now reporting the result.
