Ginkgo Biloba Extract 

Ginkgo Biloba Extract is a yellowish-brown powder extracted from the leaves of the ginkgo biloba tree. Native to China, the tree is widely cultivated. It has various uses in traditional medicine and as a source of food. Extracts of ginkgo leaves contain flavonoid glycosides (myricetin and quercetin) and terpenoids (ginkgolides, bilobalides) and have been used pharmaceutically. These extracts are shown to exhibit reversible, nonselective monoamine oxidase inhibition, as well as inhibition of reuptake at the serotonin, dopamine, and norepinephrine transporters, with all but the norepinephrine reuptake inhibition fading in chronic exposure. Ginkgo extract has in addition been found to act as a selective 5-HT1A receptor agonist in vivo. Ginkgo supplements are usually taken in the range of 40–200 mg per day. In 2010, a meta-analysis of clinical trials has shown Ginkgo to be moderately effective in improving cognition in dementia patients but not preventing the onset of Alzheimer's disease in people without dementia.
