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 ( ${circ}$ ) or doses of 1 g ( ${lozenge}$ ), 2 g ( ${square}$ ), or 3 g ( ${triangleup}$ ) 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 ( ${blacklozenge}$ ), 6 g ( ${blacksquare}$ ), or 9 g ( ${blacktriangleup}$ ) 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.
