Active constituents: The medical benefits of Ginkgo biloba extract (GBE) rely primarily on 2 groups of active components: the ginkgo flavone glycosides and the terpene lactones. The 24% ginkgo flavone glycoside designation on GBE labels indicates the proper balance of bioflavanoids. These bioflavanoids are primarily responsible for GBE's antioxidant activity and ability to inhibit platelet aggregation (stickiness). This is what may help with circulatory diseases, and support the brain and central nervous system. The terpene lactones 6% are associated with increased circulation to the brain and other parts of the body, as well as protection of nerve cells. Recent animal studies indicate that bilobalide, one of the terpene lactones, may help regenerate damaged nerve cells.

Most research studies have used between 120mg to 240mg of GBE standardized to contain 24% flavone glycosides and 6% terpene lactones. It is best taken on an empty stomach (20 min. before or 2 hrs. after food) in divided doses.

Interactions or Contraindications
GBE is safe in pregnant and lactating women. Side effects are extremely rare and mild, and might include headache and/or mild stomach upset for 1 to 2 days. GBE may potentiate or increase the effect of MAOI's, aspirin (chronic use at high doses ie: 240mg./day, and papaverine (an injection for impotence) when it is ineffective, therefore improving the effectiveness of treatment. GBE should not generally be taken with anticoagulant drugs such as warfarin (coumadin) due to its platelet inhibiting action, and increased risk of hemorrhage. However, it may be considered as a replacement therapy under the care of a physician.
