Ginkgo biloba extract is the active ingredients extracted from ginkgo leaves with advanced modern technology, its principal specifications consist in low acidity (ginkgolic acid <5ppm. 1ppm) and water solubility. The effective ingredients in the extract are flavone glycosides and terpene lactones. People use it to make dietary supplements for cognitive health. Several ginkgo studies have shown that it can help with memory problems caused by dementia or Alzheimer’s disease. It seems to help prevent the progression of dementia symptoms, especially if the dementia is thought to be the result of atherosclerotic vascular disease.
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.
