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.
Chinese medicine
Gingko roots and kernels (with greater potency in the latter) are anthelmintic, antitussive, astringent, cardiotonic and sedative; gingko is used to treat alcoholic binges, asthma, bladder infections, cough, gonorrhoea and tuberculosis. 

Herbal medicine
Gingko is used to increase cerebral blood flow, prevent blood clots, mood swings, tinnitus and vertigo, and may be effective in asthma and phlebitis.
Mainstream medicine
Mainstream pharmacologic research has shown gingkolides to be effective in treating cerebrovascular insufficiency, which causes lacunar defects of memory, migraines, strokes and vertigo.

Patient discussion about ginkgo

Q. Have food supplements like Ginkgo Biloba been proven to delay memory disorders?

A. Many people are interested in the health benefits of food supplements, hoping that natural substances can have the same efficacy as drugs. The answer to this specific question is NO. A recent study that was published after testing 3,000 people has shown no difference between those who took Ginkgo and those who didn’t. There is no food supplement, including Ginkgo Biloba that was scientifically proved to have the capacity to prevent or delay Dementia. Eating Romaine lattice, broccoli, cauliflower, and spinach have shown good results. Fish with Omega 3 have shown good results too.
