Alternative pharmacology
A tall tree native to China, the leaves of which 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. The kernals are known in traditional Chinese medicine as bai guo, Salisburia adiantifolia, white nut, ying hsing and ying xing; the root is designated bai guo gen.
