I have used it for many years for focus and concentration. I feel like it works for me but only when used consistently.
Gingko improves stamnia, improves concertation and memory retention. It can ward off the blues and controls mood swings. Increase metabolism and suppress appetite. The list is long on all the uses Ginkgo can offer, check out further detail by visiting rosemountainherb.com and select herbs and then select Gingko and it will give you alot of information and tell you all the best ways it can be bought and used. You can purchase the Gingko through other companys for cheaper, but as for the knowledge their site is good.
