Ginkgo leaf extracts contain several active constituents with neuroprotective and cardioprotective properties. These include flavonoids (e.g., rutin, quercetin, kaempferol, and proanthocyanidins), terpenoids (i.e., ginkgolides), and organic acids. Flavonoids are known to strengthen capillaries, promote healthy blood flow to the brain, and help maintain cognitive health.

Flavonoids such as quercetin and kaempferol from Ginkgo biloba are potent antioxidants and scavengers of many species of free radical, protecting against oxidative cell damage.83 Ginkgo protects the energy-producing mitochondria in the cells, thus enhancing oxygen utilization and cellular respiration.75 Ginkgo may also inhibit production of pro-inflammatory cytokines IL-1beta and TNF-alpha while upregulating the production of an anti-inflammatory cytokine called IL-10.84
