Ginkgo protects the brain after a stroke in mice

According to a report presented to the AmericanAcademy of Neurology in April, 2000, Ginkgo biloba, reduces the extent of brain damage caused by stroke induced in mice. Because of some positive results in cancer and dementia research, researches have tired to reduce damage from destructive molecules called free radicals. Free radical damage occurs after a stroke. Free radicals are like chemical “bullets” that do damage. Antioxidants are nutrients and substances found in food (like carotenoids, flavonoids, vitamins and other substances) that act like chemical “bullet-proof vests”. Antioxidants are found in ginkgo.

Researchers caused strokes in mice who had been receiving oral doses of ginkgo for one week. A low dose appeared to offer protection against stroke. It reduced the area of the brain affected by 30 % . Larger doses had no beneficial effect. Researchers caution that it is too early to recommend the use of gingko in humans at risk for stroke.
