Origin & Technology:
Ginkgo biloba is one of the world's oldest living tree species. The earliest record of the use of Ginkgo Biloba leaves as a medicine is mentioned in the Chinese Materia Medical Shen Nung Pen Tsao Ching, as an aid for blood circulation and disorders of lungs. They are also used for chilblains and as a wound plaster. In 1932, Japanese Furukawa isolated ginkgolides for the first time, which were further investigated for their chemical structure in 1966. Dr. Willmar Schwabe Company produced the first extract from leaves in 1965. With the advent and popularization of antioxidant theory in recent years, Ginkgo biloba has rapidly become one of the most widely used health supplements in the world.

Functions
The leaves are still used in Chinese medicine to treat memory loss, stomach pain, dysentery, high blood pressure and anxiety as well as other respiratory problems like asthma, bronchitis, and poor circulation. The active component of Ginkgo biloba is the terpene fraction, which consists of ginkgolides and bilobalides. These ginkgo flavone-glycosides have powerful antioxidant and free radical scavenging capability.
