Objective: To study the effect of Yangyuan Yin on decreasing alcohol in blood and protecting liver after drinking alcohol. Method: The model of alcoholic liver injury in rats was established by giving alcohol ig for 6 weeks. Meanwhile

Yangyuan Yin was given to the rats in the treatment group. By the end of the 6th week

alcohol content in blood was determined by GC

colorimetry was applied to determine ADH activity in liver and ALT

AST in blood serum. Result: Middle and high doses of Yangyuan Yin could significantly reduce the levels of alcohol and acetaldehyde in blood. Actually

the high dose could significantly improve the level of liver ADH

better than that of Haiwangjinzun. Actually

compared to the model

the activity of ALT and AST was decreased by the treatment. Conclusion: Yangyuan Yin is able to decrease alcohol in blood after drinking alcohol. The effects may be achieved by increasing the level of liver ADH.
