Ginkgo biloba is an herbal extract containing flavonoids and terpenoids, which possess antioxidant properties and may improve blood flow. It is primarily studied for its potential to support cognitive function and circulatory health, particularly in the context of age-related decline, though evidence for its efficacy in healthy individuals is weak.
Verdict
Likely ineffective for cognitive protection; potential risks outweigh unproven benefits.
