Today the ancient ginkgo has sparked renewed interest throughout the world because medical researchers have isolated chemical compounds from ginkgo that show startling effects in humans. These compounds regulate blood flow to the brain, legs and other extremities and control levels of various neurotransmitters in the brain, thus helping to counteract memory loss, depression and lack of alertness which may develop in old age. The primary therapeutic property of ginkgo is to increase the flow of blood into areas previously deprived of this life-giving substance to one degree or another, including the brain, the lower limbs, all arteries, veins, even the smallest capillaries. Decreased blood flow to the brain can adversely affect memory, concentration, intellectual ability, vision, equilibrium and balance. It may also lead to symptoms such as headaches, depression, mental confusion.
Stroke can occur because of lack of blood flow and oxygen to brain tissue.
Ginkgo is used to prevent and even treat all of these conditions. These conditions can also be caused by free radical damage. Free Radical Inhibition. Researches and empirical data suggest that free radicals are inherently involved in the aging process and in degenerative diseases such as cancer, diabetes, blindness, atheroscleriosis and so forth. Free radicals are generated by the natural metabolic processes of the body.
