Clearance rate of circulatory ethanol was definitely influenced by dietary ginseng and the differences between treatment were highly significant. On the contrary the increase in protein level did not affect the clearance rate of blood ethanol in rats. The dietary ginseng reversely affected the blood content of acetaldehyde; the higher the circulatory ethanol content, the lower the acetaldehyde content and the difference between treatments was highly significant. An increase in dietary protein level resulted in a higher content of acetaldehyde. The hepatic alochol dehydrogenase activity of rats given with one percent of dietary ginseng is definitely lower than that of control, the difference being highly significant.
