The ginkgo tree (Ginkgo biloba) has been used in China for many thousand years as medicinal preparations. Ginkgo leaves extract in both solid and liquid form has been produced both in China and elsewhere. Pharmacological properties include vasodilation and improved blood flow. It has been prescribed for the treatment of conditions associated with reduced blood flow, such as memory loss, headache, tinnitus, depression, and claudication.
