The Ginkgo (Ginkgo biloba; in Chinese 銀杏, pinyin romanization, yín xìng), frequently misspelled as Gingko, and also known as the Maidenhair Tree after Adiantum, is a unique tree with no close living relatives. The leaves are unique among seed plants, being fan-shaped with veins radiating out into the leaf blade, sometimes bifurcating (splitting) but never anastomosing to form a network. The extract of the Ginkgo leaves contains flavonoid glycosides and terpenoids (ginkgolides, bilobalides) and has been used pharmaceutically. It has many alleged nootropic properties, and is mainly used as memory and concentration enhancer, and anti-vertigo agent.
