Ginkgo Biloba

According to some studies, Ginkgo can improve attention in healthy individuals.[1],[2] In one such study, the effect was relatively quick and peaked 2.5 hours after consumption.[3]

One study suggests that Ginkgo Biloba's effect on cognition may be attributable to its inhibitory effect on norepinephrine reuptake.[4] It acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline)[5] and epinephrine (adrenaline)[6] by blocking the action of the norepinephrine transporter.

The World Health Organization[7] reports the medicinal uses of Ginkgo Biloba supported by clinical data include treatment of the effects mild to moderate cerebrovascular insufficiency.[8] Cerebrovascular insufficiency – insufficient blood flow to the brain – may manifest itself as memory deficit, disturbed concentration or headaches.

In vitro studies have demonstrated Ginkgo Biloba extracts scavenge free radicals.[9-13] This antioxidant action of Ginkgo Biloba extract may prolong the half-life of endotheliumderived relaxing factor by scavenging superoxide anions.[12],[13] The free-radical scavenging activity of Ginkgo Biloba appear to be aided by its flavonoid and terpenoid constituents.[13]
