Definition of ginkgo biloba
Ginkgo biloba is a tree species native to China and among the oldest living tree species, with individual specimens capable of surviving for an unusually long time. Extracts prepared from its leaves are widely sold as an herbal supplement, most often marketed with claims related to memory, cognitive function, and blood circulation.
Ginkgo biloba extract contains several compounds, including flavonoids and terpenoids, that have been studied for possible effects on blood vessels and cell activity, though clinical research examining ginkgo for memory loss, dementia, and related conditions has produced inconsistent results, and it is not established as an effective treatment for these conditions.
Ginkgo biloba can affect how the blood clots, an effect relevant when it is used alongside certain medications that also affect clotting, and unprocessed ginkgo seeds contain compounds considered unsafe, unlike the standardized extract typically found in commercial supplements.
