What is Ginkgo Biloba Extract?
Ginkgo biloba, also known as Maidenhair, has been traced back nearly 300 million years making it the oldest surviving tree species on earth! The Chinese have used the plant medicinally for eons but many of the modern applications come from the research of German scientists. Ginkgo is a prescription herb in Germany.


Health Benefits of Ginkgo Biloba Extract
Ginkgo extract has proven benefits to elderly people. This ancient herb acts to enhance oxygen utilization and thus improves memory, concentration, and other mental faculties. The herbal extract has also been shown to significantly improve long-distance vision and may reverse damage to the retina of the eye. Studies have also confirmed its value in the treatment of depression in elderly people. The ginkgo extract may provide relief for those who suffer from headaches, sinusitis, and vertigo. It may also help relieve chronic ringing in the ears known as tinnitus.


Reduce retinal damage
In studies, Ginkgo biloba has been reported as demonstrating antioxidant abilities with improvements of the platelet and nerve cell functions and blood flow to the nervous system and brain. It has also been reported as reducing blood viscosity. Its ability to increase vascular dilation may help reduce retinal damage due to macular degradation and may reverse deafness caused by reduced blood flow.


Healing properties
Recently, extensive research on the herb has been conducted on the healing properties of the leaf extract. Germany and France have run literally hundreds of studies on the leaf extract. These studies along with similar studies in America, have shown significant results. The extract of ginkgo biloba has been studied for its effectiveness in the treatment of acrocyanosis, Alzheimer's disease, cerebral atherosclerosis, cerebral insufficiencies, cochlear deafness, dementia, depression, menopause, peripheral and cerebral circulatory stimulation, peripheral vascular disease, Raynaud's syndrome, retinopathy, senility, short-term memory loss, tinnitus, vascular diseases, and vertigo.


Depression
Patients suffering from varying degrees of vascular insufficiency also noted an improvement in mood while taking ginkgo biloba extract. This has prompted a surge of interest in its use as a treatment for depression, especially in the elderly. Many people have found GBE to enhance other depression treatments and to often even prevent the need for pharmaceutical treatments in mild cases of depression. Those under the age of fifty may also benefit from ginkgo biloba's antidepressant effects. So far though, the greatest level of improvement has been noted with older patients.
