The dried leaves of the deciduous tree Ginkgo biloba, used for symptomatic relief of brain dysfunction, for intermittent claudication, and for tinnitus and vertigo of vascular origin.
The leaves have terpenoid derivatives known as ginkgolides A, B and C, as well as bilobalide and proanthocyanidins; as a group, these compounds have anticoagulant activity, act as free radical scavengers, increase the peripheral blood flow and are thought by some to slow age-associated memory impairment.
