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 flavone glycosides 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.


Ginkgo biloba extracts rank high among the most popular herbal products in Europe, where sales exceed $500 million annually. Ginkgo biloba extract is non-toxic, free of side effects, and safe for continuous use at the recommended intake level. Extra Strength Ginkgo Extract should be taken for four weeks or more before results can be expected.

Abstract: 112 patients (51 men, 61 women: mean age ±70.5 8.7 years, range 55-94 years) with chronic cerebral insufficiency were treated as outpatients 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 antidiabetics observed.
