Administration of 3 g American ginseng (Panax quinquefolius) reduces postprandial glycemia in type 2 diabetic individuals, with no significant additional benefit from escalating the dose to 6 g or 9 g.

If you have Type 2 Diabetes, take 3 grams of American ginseng (Panax quinquefolius) either with your meal or up to 2 hours before it to significantly blunt your blood sugar spike. You do not need to take higher doses (6g or 9g) for better results, nor do you need to worry about the exact timing as long as it is within that 2-hour window. It will not cause low blood sugar on its own.

Pairwise comparisons showed that compared with 0 g (placebo), 3, 6, or 9 g significantly (P < 0.05) reduced AUC (19.7, 15.3, and 15.9%, respectively)... However, pairwise comparisons showed no differences between the 3-, 6-, or 9-g doses... Taken together, these data indicate that 3 g administered within 2 h of the test may be sufficient to achieve reductions in PPG in type 2 diabetic individuals.
