Where are Ginkgo Biloba Extract extracted from?

Ginkgo biloba, of the family Ginkgoaceae, is a tree commonly called a living fossil, as the order of Ginkgoales which contains the family ginkgoaceae only consists of this plant, as the other members of the order that existed 190 million years ago have since become extinct. Individual trees may live as long as 1,000 years and grow to a height of approximately 38 m. Ginkgo has characteristic fan-shaped leaves. The species is dioecious. Male trees older than 20 years blossom in the spring, and adult female trees produce a plum-like, gray-tan fruit that falls in late autumn. Its fleshy pulp has a foul, offensive odor and can cause contact dermatitis. The edible inner seed resembles an almond. The leaf extract is currently one of the top 10 most popular dietary supplements in the western world, while in traditional chinese medicine the fruits and seeds were first used.
