Ginkgo has no known side effects and has been used in many long term studies. There is no addiction from continued use. Encouraged by new researches exploring the ginkgo leaf s powers Elis J. Corey, professor of chemistry at Harvard University, and his colleagues replicated the substance identified as the one most likely to have Medical applications. The synthesis of ginkgoide B was reported in the Journal of American Chemical Society. Extracts of Ginkgo are made from dried leaves.
Flavonoids are natural substances also found in fruits and vegetables.
They act as antioxidants, enhance the immune system and interfere with the formation of tumors. The type in ginkgo is called Ginkgolide. Terpene lactones are the active constituents that give ginkgo a bitter and strong flavor, and helps increase blood circulation. The active ingredients in ginkgo are believed to have their beneficial effects by thinning the blood, preventing red blood cells and platelet from clotting and, by improving the circulation in the tiny blood vessels such as the capillaries. Studies have shown that they increase the flow of oxygen to the brain, thereby increasing brain cells and working capacity.
