Ginkgo has long been cultivated in China; some planted trees at temples are believed to be over 1,500 years old. Ginkgos adapt well to the urban environment, tolerating pollution and confined soil spaces. They rarely suffer disease problems, even in urban conditions, and are attacked by few insects. For this reason, and for their general beauty, ginkgos are excellent urban and shade trees, and are widely planted along many streets.

FUNCTIONS :
1.Ginkgo biloba extract is an effective anti-oxidant.
2.Ginkgo biloba extract can promot cerebral blood circulation and cellular metabolism.
3.Ginkgo biloba extract has the function of lowering blood pressure and high blood fat.
4.Ginkgo biloba extract is tonifying kidney and nourishing brain, whitening and anti-wrinkle.

APPLICATIONS :
1.The effect on the central nervous system
Ginkgo biloba extract affects the endocrine system and the interaction between the immune system and the central nervous system by inhibiting the effect of PAF, promote brain circulation and metabolism, and improve the memory function of Chemicalbook. In addition to improving the lack of memory impairment caused by NaNO2, its anti-hypoxic effect may be related to the increase of cerebral blood flow and improvement of brain energy metabolism during hypoxia. Ginkgolide B can be used in the clinical treatment of stroke.
2. Anti-cardiovascular disease
3. Anti-aging effect
Ginkgo biloba flavonoids, isoginkgo bilobalamone, ginkgolin and quercetin in ginkgo biloba leaves all have the effect of inhibiting lipid peroxidation, especially quercetin has stronger inhibitory activity.
4. Antioxidant effect
Ginkgo biloba extract can directly scavenge lipid free radicals, lipid peroxidation free radicals and alkane free radicals, and terminate the chain reaction chain of free radicals.
