Plant Origin:Ginkgo Biloba L. Specification: 1.24%/6% HPLC 2.24%/6% HPLC Ginkgolic acid<5ppm HPLC 3.24%/6% HPLC Ginkgolic acid<1ppm HPLC Action:Ginkgo biloba extract (GBE) increases blood flow to the brain by inhibiting blood platelet aggregation and by regulating blood vessel elasticity; it has been shown to improve blood flow through both major blood vessels and capillaries. Ginkgo is also a powerful antioxidant. Ginkgo biloba extract has two major groups of components, ginkgo flavonglycosides and terpene lactones. Its efficacy depends on their proper balance and a standardized extraction method has been developed to ensure that balance. Basically, these two constituents or groups of constituents are responsible for ginkgo bilobas two main properties: the ability to inhibit blood platelet aggregation (which allows for greater flow of blood to the brain and extremities) and its strong antioxidant properties (which exert a protective influence over the brain and CNS).
