Type 2 Diabetes
Blood glucose is one of the few areas where ginseng has moderate-quality human evidence, but "moderate" and "small" belong together: pooled randomized trials show fasting glucose does fall a little, to a statistically significant degree, while HbA1c, fasting insulin and insulin resistance do not improve. Because it really does lower glucose a little, adding it on top of diabetes medication carries a risk of low blood sugar.

Cognitive Aging & Reserve
Sharpening the mind and memory is ginseng's second-biggest selling point, and a Cochrane systematic review concluded there is no convincing evidence that it improves cognition in healthy people. Not because the trials all came out negative, but because no credible effect can be pooled from them: they used different outcome measures, durations and doses, and every usable trial was in healthy people.

READ THE ORIGINAL

What does the work when ginseng enters your body is not the "replenishes vital energy" printed on the box, but a large family of molecules in the root: ginsenosides.

They are not one molecule but a whole family with different structures. In cell and animal experiments they reach many places: the lining of blood vessels, the brain, the pancreas and muscle, immune cells. In people, the effects are mostly mild, short-lived, and uneven from study to study — a long way from a cure-all.

So "does ginseng work?" is the wrong question, because it never says which box of ginseng. The question that can be answered is: which ginsenoside, how much of it reaches your blood, and what outcome the trial measured. If the box on the shelf (Panax ginseng, also called Asian or Korean ginseng) does not state even these, it cannot be matched to any study.
