Ginsenosides are major constituents of ginseng and are known to be responsible for its pharmacological properties. This study aimed to investigate the detoxification effect of a mixture containing black red ginseng powder, red ginseng extract, Puerariae radix extract, and Hovenia dulcis extract, on SD (Sprague Dawley) rats treated with 30% ethanol. Thirty minutes before treatment, the animals were orally administered different concentrations of the mixture or water. Results revealed that the concentration of ethanol in blood serum was significantly decreased in the black red ginseng mixture treated group in a dose-dependent manner, as compared with that of the control group. The blood level of acetaldehyde increased until 1 hr after alcohol administration, but the levels rapidly decreased later. Furthermore, ADH and ALDH activities in the hepatic tissue were also increased in the black red ginseng mixture administered group, than in the control group. These results indicate that the black red ginseng mixture has the ability of decomposing alcohol by increasing the ADH and ALDH activities responsible for alcohol metabolism.
