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 flavonglysosides 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.
Discussion
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. Best Ginkgo Extract should be
taken for four weeks or more before results can be expected.

cerebral insufficiency in geriatric patients,” Clinical Trials Journal 1985
22(2): 149-157.
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.

Abstract Electroencephalography is the only convenient method for functional
exploration of the brain. The recent introduction of signal analysis techniques
has given it a quantitative dimension and has resulted in pharmacological
studies of electroencephalograms. In four studies of this kind, the effects of
Ginkgo biloba extract were investigated on three pathological animal models, in
healthy young volunteers and in elderly people with demential disorders. In
man, the EEG tracings could be analyzed in relation to different psychometric
tests. The results obtained confirm those of clinical trials, and notably the
activity of Ginkgo biloba extract on alertness.
