Leaves of the common ginkgo biloba tree provide the origin of this therapy. The tree is very old; its fossil record dates back 200 million years. The extract is created through a complicated process, but the result contains bioflavonoids and terpene lactones as active ingredients. The extract increases blood flow to the brain and small blood vessels by inhibiting platelet aggregation and by regulating blood vessel elasticity. Ginkgo biloba is also a powerful antioxidant. The proper treatment seems to be a combination of about 25% bioflavonoids and 6% terpene lactones at a dose of 80 mg 3 times a day. Effects may not be observed for up to 12 weeks, so therapy should continue for at least that long. Because ginkgo affects platelet aggregation, a bleeding time should be checked if ginkgo is used for more than 4 continuous weeks.
