Plant preparations contain plenty of different phytochemical substances, includind aliphatic alcools, ketons, organic acids, sesquiterpenes, glycosidic derivatives; from a health perspective the most interesting substances are flavonoids (flavanols like quercetin, kaempferol, PAC) and diterpenes (mainly ginkgolides).

Extracts of ginkgo leaves are indicated for preventing or reducing the effects of senile cerebral insufficience, memory loss, mild symptoms of alzheimer disease, defects in peripheral circulation, claudication, tinnitus and hear loss.

Ginkgo extracts are rich in antioxidant molecules and are able to inhibit platelets aggregation, which are key features for preventing circulatory troubles.
