Ginkgo biloba is the world's oldest species of tree; its ancestors date back 200 million years. Ginkgo is native to China, where it is considered a sacred tree. In traditional Chinese medicine, ginkgo is believed to benefit the brain. In Germany and France, where ginkgo is prescribed like a drug, ginkgo leaf extract accounts for more than 1 percent of drug sales (1).
Ginkgo seems to increase blood flow to the brain, improving the supply of oxygen and glucose. At the cellular level, ginkgo stabilizes membranes, scavenges toxic free radicals, stimulates enzymes that relax arterial muscles and inhibits blood platelet clotting (2).
More than a dozen clinical studies have been conducted in Europe that show that ginkgo can reduce mental decline (3-6). The most recent American clinical study has proven ginkgo as effective as any known drug in treating Alzheimer's dementia (7). |
