I was poking around the web, and came across this link that shows a lot of scientific research (yes, real science) done on ginseng. It seems to have a lot of positive effects, however they are almost all minor. But still, if a glass is full, just a drop will make it flood, so even minor changes can make a big difference.
I did a little (as in not much) background research on examine.com and it seems legit, not making any claims them selves, but rather… Showing the Science. Please correct me if I’m wrong on this.
