[American ginseng compound liquor on retarding-aging process].

71 cases with age over sixty were randomly divided into treated group and control group, and observed by single-blind method. 36 cases were administered with American ginseng compound liquor as a treated group, 35 cases were administered with American ginseng liquor only as a control group. The total effective rates of the treated group and the control group on symptoms associated with aging were 88.89% and 68.57% respectively (P less than 0.05). The effective rates of the treated group for Kidney-Yang, Kidney-Qi and Kidney-Yin deficiencies were 85.71%, 100% and 87.50% respectively. The effective rates of the control group were 81.82%, 100% and 61.53% respectively. The above results indicated that the symptoms of Kidney-Yang deficiency in the treated group were improved much better than those of the control group (P less than 0.05). Obviously, SOD activity of erythrocyte and SOD/LPO ratio increased remarkably and serum content of LPO decreased significantly in both groups (P less than 0.001). In the treated group, the functional months of age (physiological age) decreased from 751.77 +/- 5.215 to 743.53 +/- 5.144, the effective rate was 68.57%. It showed that these two recipes both had the efficiency on prolonging the functional age (P less than 0.05).
