Ginkgo Biloba trees (Maidenhair Tree) have been in existance for thousands of years and has been used in chinese medicine for thousands of years. The leaves of the gingko tree are used for medicinal purposes. The medicinal benefits of the extract of gingko biloba are derived from two groups of active constituents, the ginkgo flavone glycosides and the terpene lactones.

Gingko flavone glycosides normally make up approximately 24% of the extract and contribute to the antioxident activity of Gingko biloba and the mild ability to support blood viscosity.

Gingko biloba supports the circulatory system and the nervous system, where it is supportive for brain activity. Gingko may also provide support for vision and also has a strong antioxidant activity and is useful to prevent free radical damage to the body cellular structure.
