Ginseng has been used in traditional wellness practices for thousands of years. But do the benefits stack up? There aren't any approved claims about ginseng in the UK, but emerging research looks at potential benefits for
focus,
sexual function in men,
cholesterol levels and more. Research has explored ginseng in a number of areas, including
cognition and cardiovascular health, although findings have been mixed and more research is needed.
In one small study involving 16 healthy adults, researchers reported differences in performance on short-term working-memory tasks following ginseng supplementation compared with placebo.
3 Another study involving 50 healthy adults experiencing
fatigue reported a small difference in reaction-time scores on attention and memory tests after participants took 210mg of a ginseng extract, both after a single dose and following repeated use.
4 A meta-analysis of 23 studies also reported lower LDL cholesterol levels among participants taking ginseng compared with placebo.

These findings need to be interpreted with caution and they don't establish that drinking ginseng tea will produce the same effects. In particular, the studies investigated specific ginseng preparations, including concentrated extracts provided in capsules, which aren't directly comparable with a cup of ginseng tea. More research specifically investigating ginseng tea is needed before conclusions can be drawn about its effects.
