ginkgo biloba a powerful antioxidant for vision

Many scientists believe that ginkgo biloba is one of oldest living species of tree. Ginkgo trees can live up to 1,000 years. The leaves of the tree are used for their medicinal effects. Ginkgo biloba has antioxidant powers in the brain, retina of the eye, and in the cardiovascular system. Research shows that Ginkgo biloba can help people with macular degeneration, an oxidation-related disorder causing decreased or lost vision. A study showed that ginkgo improved the distance-vision of people who showed signs of degeneration in the retina. Macular degeneration, a leading cause of blindness, is strongly related to hemorrhages in the fine blood vessels in the eye, possibly due to oxidative stress. By strengthening the tiny blood vessels in the eye, and by acting as an antioxidant, ginkgo provides a strong protection against eye diseases. Ginkgo biloba mainly has two active ingredients: flavone glycosides and terpene lactones. Ginkgo flavone glycosides are primarily responsible for ginkgos antioxidant effects and the terpene lactones are responsible for Ginkgo's ability to increase blood circulation to the brain and other parts of the body.
