Ingredients
World's Oldest Living Plant
Ginkgo Biloba extract is derived from the Ginkgo Biloba tree leaf. Thriving on earth for more than 200 million years, the ginkgo tree is the world's oldest living plant. Considered sacred in the Orient, ginkgo was the only surviving tree near the epicenter of the Hiroshima atomic bomb blast. One specimen planted near a Japanese monastery more than 1,000 years ago, is still alive today. Rich and Concentrated The Ginkgo Biloba leaf is rich in phytonutrients, chiefly flavonglycosides and terpene lactones (ginkgolides). In the extract, these bioflavonoid-like active ingredients are highly concentrated. Fifty pounds of Ginkgo leaves are used to yield one pound of extract.
Benefits
Brain and Mental Function
Numerous clinical studies have been published on Ginkgo biloba extract. Much of this extensive research deals with Ginkgo's beneficial effects on the brain and mental function.
Supports Circulation
Foremost among its actions, Ginkgo biloba extract supports circulatory function in the brain and also in the extremities. Enhanced blood flow to the brain means better delivery of oxygen and nutrients.
Many Observed Benefits
The clinically observed benefits of Ginkgo biloba extract include improved short-term memory, and a positive effect on mood, sociability, thinking ability and hearing.
Powerful Antioxidant
Ginkgo biloba extract is a powerful antioxidant. Acting as free-radical scavengers, Ginkgo's flavonglycosides help prevent damaging peroxidation of cell membrane lipid components.
Platelet Activating Factor (PAF)
The ginkgolides have been shown to inhibit Platelet Activating Factor (PAF). Controlling PAF reduces clumping of blood platelets and improves circulatory health.
Oxygen Delivery
By maintaining blood flow in the extremities, Ginkgo biloba extract supports oxygen delivery to tissues and promotes ability to walk without discomfort.

Abstract: 112 patients (51 men, 61 women: mean age about 70.5 8.7 years, range 55-94 years) with chronic cerebral insufficiency were treated as out-patients in several German test centers with Ginkgo biloba extract at 120 mg/day in an open one-year trial. Results showed a statistically significant (P < 0.001) regression of the major symptoms of vertigo, headache, tinnitus, short-term memory, vigilance and mood disturbance. Heart rate and blood pressure modifications were not detected. Laboratory mean levels of blood cholesterol and triglycerides remained practically unchanged during the period of the trial. Significant side-effects did not occur throughout the study, nor were significant interactions with existing basic medications such as cardiac glycosides or anti-diabetics observed.
