Function:
1.Promote circulation
Ginkgo Biloba Extract Powder, an extract of Ginkgo biloba, stimulates the circulation of both the brain and the limbs of the body. One of the main health benefits of Ginkgo biloba P.E. is the inhibition of a substance called platelet activating factor (PAF), a mediator released from cells that causes platelets to clump together (clump together). High levels of PAF can cause nerve cell damage, decreased blood flow to the central nervous system, inflammation, and bronchoconstriction. Much like free radicals, high PAF levels can also lead to aging. Ginkgolide and bilobalide protect nerve cells in the central nervous system from damage during periods of ischemia (lack of oxygen to tissues in the body). This function may be useful in adjuvant therapy for patients suffering from stroke. In addition to inhibiting platelet adhesion, Ginkgo biloba extract regulates vascular tone and elasticity. In other words, it makes blood vessel circulation more efficient. This circulatory efficiency-enhancing effect affects both the large blood vessels (arteries) and the smaller blood vessels (capillaries) in the circulatory system.
2.Anti-oxidation
It may exert antioxidant properties in the brain, eye retina and cardiovascular system. Its antioxidant effects in the brain and central nervous system may help prevent age-related decline in brain function. The antioxidant properties of Ginkgo biloba extract in the brain are of particular interest. The brain and central nervous system are particularly vulnerable to free radical attack. Brain damage caused by free radicals is widely believed to be a contributing factor in many diseases that accompany aging, including Alzheimer's disease.
3.Anti-Aging
Ginkgo biloba extract Ginkgo biloba P.E. increases blood flow to the brain and has an excellent tonic effect on the nervous system. Hundreds of scientific studies involving tens of thousands of patients have confirmed the efficacy of Ginkgo biloba extract against a number of problems including insufficient blood flow to the brain and mental decline in elderly patients. Ginkgo is good for many possible symptoms of aging, such as: Anxiety and depression, memory impairment, difficulty concentrating, decreased alertness, decreased intelligence, dizziness, headache, tinnitus (ringing in the ears), macular degeneration (most common cause of blindness in adults), disturbance of the inner ear (which can lead to partial deafness), poor circulation to the end, impotence due to poor blood flow to the penis.
4.Fight dementia
Alzheimer's disease and memory improvement
Scientists reviewed all published high-quality research on ginkgo and mild memory impairment and concluded that ginkgo was significantly more effective than placebo in improving memory and sensory function. Ginkgo is widely used in Europe to treat dementia. Ginkgo is thought to help prevent or treat these brain disorders because it increases blood flow to the brain and its antioxidant properties. Despite the scientific flaws in many clinical trials, evidence that ginkgo may increase thinking, learning and memory in Alzheimer's patients is still highly anticipated.
5.Mediation of unhappiness before menstruation
A double-blind, controlled placebo study evaluating the benefits of Ginkgo biloba P.E., an extract of Ginkgo biloba, in women with premenstrual discomfort symptoms, including 143 women aged 18-45, followed by two menstrual cycles. Each woman received Ginkgo biloba P.E. (80 mg twice daily) or placebo on Day 16 of the first cycle, and treatment continued until Day 5 of the next cycle, and during that cycle restarted on day 16. The results are impressive. Compared with placebo, ginkgo significantly reduced the main signs of premenstrual discomfort symptoms, especially breast pain and emotional instability.
6. Improve sexual function
Although there is no double-blind trial basis for this function, case reports and open-label studies suggest that Ginkgo biloba can improve sexual dysfunction caused by polozac and other antidepressants.
7.Regulate eye problems
The flavonoids in ginkgo may stop or ease some retinopathy. There are many possible causes of retinal damage, including diabetes and macular degeneration. Maculopathy (commonly referred to as age-related macular degeneration or ARMD) is a progressive degenerative eye disease that tends to occur in older adults. It is the leading cause of blindness in the United States. Research suggests that ginkgo may help preserve vision in people with ARMD.
Dosage: The prevailing opinion is that a dose of 120-160ml per day is appropriate for the treatment of terminal microcirculation problems including vertigo, tinnitus and intermittent claudication. For dementia, mild depression and cognitive enhancement, higher doses (approximately 240mg/day) may be used. For best results, the daily dose is generally divided into 2-3 doses. The criteria for validating the use of the extract is that it contains at least 24% ginkgo flavonoid glycosides and 6% terpene lactones - as this is the level at which the extract has shown substantial efficacy in each clinical trial.
8.Treat high blood pressure
It can simultaneously reduce the adverse effects of blood cholesterol, triacylglycerol, and very low density lipoprotein on the human body, reduce blood lipids, improve microcirculation, and inhibit blood coagulation. These have significant therapeutic effects on hypertension.
9.Treat diabetes
In medicine, Ginkgo biloba extract has been used to replace insulin for diabetics, indicating that Ginkgo biloba has the function of insulin to regulate blood sugar. Many glucose tolerance tests have proved that Ginkgo biloba extract can regulate blood sugar and improve insulin resistance. Thereby reducing insulin antibodies and enhancing insulin sensitivity.
