Ginkgo leaf (Ginkgo Biloba) is thought to improve circulation help maintain memory with age and to support healthy cognitive function.

The benefits of Ginkgo biloba extract (GBE) are attributed primarily to two groups of active constituents: the ginkgo flavone glycosides and the terpene lactones
Native to China, though no longer found growing wild, the Ginkgo tree is cultivated commercially in large scale plantations in China, in France near Bordeaux and in South Carolina, USA. The leaves are harvested in the autumn
