Fig. 1. The aggregate acute treatment effect of Asian ginseng on plasma glucose and insulin for two studies. The line plots and bars represent the incremental and AUC plasma glucose and insulin responses following the mean of two placebos (3 g and 9 g) (•) or the mean of doses from 1–9 g (1–3 g and 3–9 g) (
) taken 40 minutes before a 75 g oral glucose tolerance test (75 g-OGTT) in two studies each with 11 healthy, nondiabetic participants, in which each subject did all treatments in a single-blinded, randomized, multiple crossover design. Data are mean ± SEM.
