Product Description

Ginkgo biloba, or ginkgo biloba leaf extract, is an herbal supplement extracted from ginkgo biloba tree leaves. Often used in Traditional Chinese medicine (TCM), it is believed to help improve memory, brain function, and blood flow.

Active ingredients in the leaves include terpene lactones (terpenoids) and ginkgo flavone glycoside (flavonoids). These compounds have an antioxidant effect that may help prevent tissue damage and disease.3 In addition, the flavonoids in ginkgo also promote blood flow.

Because of these active ingredients, ginkgo biloba extract supplements may help improve brain function and blood circulation related to blood pressure, memory, and eye health. However, there is not enough information to prove ginkgo biloba improves any health conditions.
