Preventive effect of the saponin fraction extracted from Panax ginseng C.A. Meyer against ethanol intoxication of the liver has been investigated biochemically and morphologically. Previous work in this laboratory showed that the moderate amounts of ginseng sponins stimulated several enzymes including mitochondrial dehydrogenases and transaminases so far examined in vitro. It was also realized that the half life of the saponin in the liver was estimated approximately five hours and the saponin concentration in the liver was around $10^{-5}\%$ level at two hours after the saponin (1mg) administration orally. In this study, it was confirmed that ginseng saponins stimulated alcohol dehydrogenase, aldehyde dehydrogenase and microsomal ethanol oxidizing system in vivo as well as in vitro. It seemed likely that toxic aldehyde formed during ethanol oxidation in the body might be removed relatively quickly from the liver and the excess hydrogen was used for the biosynthetic work in the presence of the saponin, resulting in the liver protection from alcohol intoxication. Electron microscopic observation demonstrated that the hepatocytes of rats doses with $12\%$ ethanol instead of water for six days were found severely damaged while those of the ginseng saponin administered rats were not impaired suggesting that the sapcnin protected the liver against ethanol intoxication.
