A species of tree. In an extracted form, the leaves of the ginkgo biloba plant may promote healthy blood circulation when applied topically.

Ginkgo Biloba is sometimes used in lubricants to provide a stimulating effect, which may allow for heightened sensations and a better overall sexual experience. Ginkgo is generally a safe substance when applied topically, but it may cause serious side effects for people with circulatory disorders when taken internally. However, most “stimulating” lubricants contain a relatively small amount of this ingredient.
