Ginkgo biloba for Cerebrovascular Health
BResearch suggests Ginkgo may help enhance cerebral blood flow through vasodilation. More consistent benefits are observed for vascular-related cognitive symptoms than for general cognitive decline.
The Bottom Line
Research suggests Ginkgo may help enhance cerebral blood flow through vasodilation. More consistent benefits are observed for vascular-related cognitive symptoms than for general cognitive decline.
