Fig. 2. Acute dose effects of Asian ginseng over a 1–9 g dose range on plasma glucose and insulin in two studies: (A) Study 1—the line plots and bars represent the incremental change and AUC for plasma glucose and insulin following placebo (
) or doses of 1 g (
), 2 g (
), or 3 g (
) of Asian ginseng taken 40 minutes before a 75 g oral glucose tolerance test (75 g-OGTT) in 11 healthy, nondiabetic participants, in which each subject did all treatments in a single-blinded, randomized, multiple crossover design. (B) Study 2—the line plots and bars represent the incremental change and AUC for plasma glucose and insulin following placebo (•) or doses of 3 g (
), 6 g (
), or 9 g (
) of Asian ginseng taken 40 minutes before a 75 g oral glucose tolerance test (75 g-OGTT) in 11 healthy, nondiabetic participants, in which each subject did all treatments in a single-blinded, randomized, multiple crossover design. Data are mean ± SEM.
