2.antioxidant
Ginkgo biloba P.E. may play an antioxidant role in the brain, retina and cardiovascular system.Its antioxidant activity in the brain and central nervous system may help prevent age-related decline in brain function.Ginkgo biloba extract is particularly interesting in the brain’s antioxidant function.The brain and central nervous system are particularly vulnerable to free radical attacks.Free radicals cause brain damage that is widely believed to be a factor in the many diseases associated with aging, including alzheimer’s disease.
3.anti-aging
Ginkgo biloba P.E. improves cerebral blood flow 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 in many problems, including the lack of blood flow in the brain and the mental decline of older patients.Ginkgo biloba for many aging symptoms may have good effect, for example: anxiety and depression, memory impairment, difficulty concentrating, loss of alertness, mental decline, dizziness, headache, tinnitus (ringing in the ears), macular degeneration, the most common cause of adult blindness), inner turmoil (it will lead to partial hearing loss), at the end of cycle of poor, poor blood flow to the penis, impotence.
4.Combat dementia
Alzheimer’s disease and memory improvement.
Scientists reviewed all published the quality study of ginkgo biloba and mild memory impairment, and came to the conclusion: ginkgo biloba on improve memory and cognitive function significantly more effective than placebo.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 function.Although many clinical trials are scientifically flawed, ginkgo may increase the ability of patients with alzheimer’s to think, and evidence of learning and memory is still widely expected.
5.The mediation was unpalatable.
An evaluation of Ginkgo biloba extract Ginkgo biloba Joseph t. benefits for women with premenstrual discomfort symptoms of double-blind controlled placebo research, the trial included 143 women aged 18 to 45 years old, and track them two menstrual cycles.In the 16th day of the first cycle every women received Ginkgo biloba extract Ginkgo biloba Joseph t. (80 mg twice a day, every time) or placebo, treatment last into the next cycle of 5 days, and in the 16th day of the cycle starts again.The results were impressive.Compared with placebo, ginkgo significantly reduced the symptoms of premenstrual symptoms, especially breast pain and emotional instability.

7.Adjust eye problems
Flavonoids in ginkgo may stop or alleviate some retinopathy.There are many possible causes of retinal damage, including diabetes and macular degeneration.Macular lesions (commonly referred to as age-related macular degeneration or ARMD) are progressive degenerative eye diseases and are prone to ageing.It is the leading cause of blindness in the United States.The study suggests that ginkgo may help preserve the vision of patients with ARMD.
Dose: the prevailing opinion is that 120-160ml per day is suitable for treatment of end microcirculation problems, including vertigo, tinnitus and intermittent claudication.For dementia, mild depression and cognitive enhancement, higher doses can be used (approximately 240mg/ day).For best results, the daily dose is generally divided into 2-3 doses.The standard for the use of extract was confirmed to contain at least 24 percent of ginkgo flavonoids and 6 percent of terpene lactone – because this is the level of extract in each clinical trial.
8.Treatment of hypertension
Ginkgo biloba extract can reduce blood cholesterol at the same time, three acyl glycerin, very low density lipoprotein, adverse effects on the human body, reduce blood fat, improve microcirculation, inhibit blood coagulation, the treatment for hypertension effect is remarkable.
9.Treat diabetes
Now have the use of ginkgo biloba extract on medicine instead of insulin for diabetics use drugs, that ginkgo biloba have the function of insulin to regulate blood sugar, many of the glucose tolerance test proved that ginkgo biloba extracts to regulate blood sugar, improve insulin resistance, thus reducing insulin antibodies, increase insulin sensitivity effect is obvious.
