Ginkgo Leaf Extract

Botanial information:

Ginkgo , has some other names like Japanese Silver Apricot, Kew Tree, Maidenhair Tree, and Yinhsing is thought to be the oldest tree species on the earth: with fossilized ginkgo dated at over 220 million years old. Furthermore, historical records kept in China may place the age of individual, still-living ginkgo trees at 1,000 years or older. Under favorable growing conditions, ginkgo trees may reach over 100 feet in height. However, the ginkgos most familiar to residents of the United States are generally small trees.

Standard extract effect and application:

1)Increasing amounts of evidence show that herbal products made from ginkgo leaves may help to relieve a condition known as cerebral insufficiency, which is a decrease in the blood supply to the brain. Chemicals in ginkgo leaves are known to thin the blood and they may also normalize muscle tone in blood vessel walls. Both of these effects may improve blood flow to the brain, thereby increasing oxygen and possibly relieving conditions associated with poor blood flow.

2)Ginkgo leaf may also help to prevent or relieve some eye conditions. In both animal and human studies, taking ginkgo leaf has restored at least part of color perception for individuals who have decreased vision due to diabetes. Some evidence also suggests that ginkgo may also help to improve age-related macular degeneration (AMD), which is the destruction of the retinas centers. AMD may destroy vision in the center of the visual field and it may lead to blindness.

3)In addition, ginkgo has shown a protective effect against some forms of glaucoma, a disease caused by increased pressure within the eyes.

4)Taking ginkgo leaf preparations helps to relieve conditions such as intermittent claudication, which is leg pain that occurs while walking. Intermittent claudication usually results from peripheral vascular disease : narrowing of blood vessels that may cause an inadequate blood flow to the arms and legs.

5)Ginkgo leaves have also been studied for increasing the ability to tolerate cold temperatures. In a condition known as Raynaud syndrome or Raynaud phenomenon, spasms of the blood vessels in the ears, fingers, toes, and other outer parts of the body cause the blood vessels in these areas to narrow when they get cold or during times of emotional stress. The vessel-widening chemicals in the leaves of ginkgo may prevent these spasms and the pain they cause.

6)For ginkgo may increase blood flow to the penis, it has also been studied for the treatment of erectile dysfunction (ED), the inability for a man to have or maintain an erection. A few small human studies show that ginkgo may have limited effectiveness for treating ED, especially for men who have ED as a side effect from taking antidepressant medications.

7)Ginkgo leaf extract has also reduced chemically-caused liver fibrosis in animal studies. Fibrosis is the formation of scar-like fibers in the liver. Because the non-functioning fibers crowd out active liver tissue, liver function decreases gradually as the amount of fibrous tissue increases.

8)Roasted ginkgo seeds may sometimes be used to treat chronic respiratory conditions such as asthma.
