Many people, especially students, have been using Ginkgo biloba as a natural brain booster. Researchers have now found that Ginko could additionally protect against brain damage following a stroke.

In one of the recent studies, rodents have received a100 milligrams per kilogram oral dose of the Ginko extract for a week, after which they had been induced a stroke. Various tests have then been used to assed their brain functioning and damage that occurred in the mice. Mice pretreated with the supplement had 50.9 percent less neurological dysfunction and 48.2 less brain damage when compared to the mice who did not receive ginkgo biloba prior to stroke induction.

Brain damage from stroke occurs from either lack of blood in brain cells or because of an increase in free radicals at the stroke site when the blood flow is restored. Free radicals are oxygen molecules that harm cells. Tissue plasminogen activator (tPA) is currently the only FDA-approved drug for treating stroke. It is designed to dissolve blood clots, but can not protect from cell damage when the blood flow returns.
Researchers say ginkgo biloba appeared as a good preventive treatment option.

If additional studies confirm these results, a daily regimen of ginkgo to people at high risk of stroke can be used as a preventive measure against brain damage.
