Ginkgo (Ginkgo biloba), also spelled gingko, also known as the Maidenhair Tree, is a unique species of tree with no close living relatives. The tree is the national tree of China. It has also been commonly cultivated in North America for over 200 years, but during that time it has never become significantly naturalized.

 The nut-like gametophytes inside the seeds are particularly esteemed in Asia, and are a traditional Chinese food. In Chinese culture, they are believed to have health benefits; some also consider them to have aphrodisiac qualities.

Ginkgo biloba leaf Extract (GBE) contains Ginkgo flavone glycosides and Terpene lactones, and have been used pharmaceutically. The flavone glycosides, such as keampferol, quercetin, isorhamnetin, have anti-oxidant and free radical properties. The ginkgolides, which are trilactonic diterpenes, include ginkgolide A, B, C. GBE is standardized to contain 24% Ginkgo flavone glycosides and 6% terpene lactones including Ginkgolide A,B,C and bilobalide. Ginkgo supplements are usually taken in the range of 40–200 mg per day.

Both the leaves and the seeds have been used in Traditional Chinese Medicine. This ancient remedy has been recommended for coughs, asthma and inflammations due to allergies. Today the clinical experience in China has focused on using tablets or injectable drug forms in the treatment of angina pectoris, chronic bronchitis, and its effect on lowering serum cholesterol levels.

The standardized extract of the leaves has been used extensively in Europe for two decades. Because of wide restorative effects, its excellent safety, also with the increasing population of the aged, the standardized extract of the leaves will surely have more and more important function for people's health and lives.Ginkgo leaf extract (GBE) is now among the leading prescription medicines in both France and Germany, where they account for 1.0 and 1.5 percent, respectively, of total prescription sales.
