Objectives : This experiment was conducted to verify the effects of some oriental herbs(Alny Cortex et Ramulus, Artemisiae Capillaris Herba, Aurantii Nobilis Pericarpium, Giseng Radix, Hoveniae Semen, Puerariae Flos, Puerariae Radix, and Xanthii Fructus) which have been used in the treatment of alcoholic diseases, on alcoholic metabolism, and on alcoholic liver damage. Methods : The effects of the herbs on the activities of alcohol dehydrogenase(ADH), aldehyde dehydrogenase(ALDH) were evaluated and their protective effects of liver function and cells from alcoholic damage were analysed. For the evaluation of the protective effects, the levels of glucose, triglyceride, BUN, AST, and ALT in serum of rats were measured. Results and Conclusions : It is concluded that Puerariae Radix interferes with the ADH activity directly, thereby reducing the toxicity of alcohol, resulting in enhancing alcohol-tolerance and protecting liver functions. Also Artemisiae Capillaris Herba interferes both ADH and ALDH activities. Isolation of the biologically active compounds from Puerariae Radix and its detailed characterization are matters for future research.
