Effect of dose (placebo, 3g, 6g or 9g) of American ginseng (Panax quinquefolius L.) independent of time of administration on (A) incremental changes in glycemia at selected time intervals (15, 30, 45, 60 and 90 minutes) and (B) glycemic area under the curve (AUC) following a 25g oral glucose challenge in 10 nondiabetic individuals. Points at the same time interval and bars with different letters are significantly different (p<0.05; repeated measures two-way ANOVA adjusted for multiple Pairwise comparisons with the Newman-Keuls procedure).
