Ginkgo biloba leaves enhance memory? Doctors and pharmacists solve the myth of ginkgo biloba against dementia!

Editor's note: Should I eat Ginkgo biloba for memory loss? Can Ginkgo biloba resist dementia? Are you really suitable for taking ginkgo supplements? Doctor Yamatonokusushi tells you the real efficacy of Ginkgo biloba leaves, and then further clarifies how to eat them! Jiang Shoushan's Ginkgo biloba leaves are suitable for people with these troubles, such as Alzheimer's disease, dementia and other people with poor family history. I want to improve PMS and prevent glaucoma, macular degeneration, dizziness, tinnitus, diabetes, cold limbs and poor peripheral blood circulation. Six health skills of ginkgo biloba! Ginkgo biloba has existed on the earth for at least 270 million years, so it is called a living fossil by Darwin. It is an ancient medicinal material in China. According to Compendium of Materia Medica, the fruit of Ginkgo biloba L. has the effects of warming lung, invigorating qi, relieving asthma and relieving cough, and Ginkgo biloba can treat chest distress and heartache and improve blood circulation. Ginkgo biloba was introduced into Europe in the 1970s, which set off a research upsurge in Germany and France. Now, in Germany and France, Ginkgo biloba extract is made into tablets or intravenous drugs, which has become a clinical prescription for doctors. It has been proved that Ginkgo biloba leaves can improve cerebral blood flow. Julien Moore, a movie star who protects brain nerve cells, won the Best Actress Oscar in 20 15 years for Still Alice, which not only made her the first Grand Slam winner to win the Golden Globe Award, the British Film Academy Award and the Oscar Award in history, but also aroused the public's attention and understanding of diseases such as Alzheimer's disease and dementia. In order to prevent this disease that will permanently lose memory, people began to look for nutritional supplements to prevent mental decline and improve memory. However, although there are many such products on the market, most of them are groundless. Only two studies have confirmed the effect, one is fish oil and the other is ginkgo biloba. Ginkgo biloba is not only the best-selling health care product in the United States to improve memory, but also is often prescribed by doctors in Europe to treat "cerebral blood supply deficiency". Many high-quality double-blind controlled studies show that Ginkgo biloba leaves can slow down the deterioration of diseases such as Alzheimer's disease and dementia, activate human brain function and enhance memory. 1997, new york Medical Center in the United States found that Ginkgo biloba can slow down the progression of Alzheimer's disease. They extracted a substance called "EGb76 1" from Ginkgo biloba leaves, and asked the experimenters to take 40 mg, 120 mg and 240 mg of placebo and Ginkgo biloba extract respectively. It was found that patients who took Ginkgo biloba extract deteriorated more slowly and their memory was improved than other patients who took placebo. A 22-week follow-up study in 2006 also confirmed that the curative effect of Ginkgo biloba is no less than Donepezil, a drug for treating Alzheimer's disease. In 2007, a study of 400 patients with Alzheimer's Harmo's disease showed that patients' cognitive ability was significantly improved after taking 80 mg of Ginkgo biloba extract three times a day. Another randomized controlled study, published in BMC Medical Journal, aimed at 2,372 patients with Alzheimer's disease or Harmo's disease, showed that taking Ginkgo biloba improved their cognition and daily life. The help of Ginkgo biloba leaves to the brain is mainly related to improving cerebral blood flow and the activity of nerve cells. Because if the brain doesn't get enough blood and the blood supply to the cerebral vessels is insufficient, it will affect nerve cells, which will cause headaches, poor memory and inattention. Flavonol contained in Ginkgo biloba leaves can improve the blood circulation of human body (including peripheral blood circulation), increase the oxygen supply of heart, brain and other organs, help restore the blood flow of brain, improve the phenomenon of insufficient blood flow of brain, and protect nerve cells from further damage. Ginkgo biloba can not only be used to prevent and treat brain diseases such as Alzheimer's disease and dementia, but also help ordinary people. Because even without Alzheimer's disease, dementia and other brain diseases, the blood flow to the brain will gradually decrease with age. If it is reduced too much (that is, the blood flow in the brain is insufficient), it will cause memory loss and even other cognitive dysfunction. A study by the University of Leeds in the United Kingdom also showed that eight healthy volunteers aged 25 to 40 took EGb76 1 extracted from Ginkgo biloba leaves every day, which significantly improved their memory and enabled them to concentrate more on their work. Another test on 40 healthy silver-haired people aged 55 to 86 also showed that these elderly people's thinking ability and reaction became better after taking Ginkgo biloba leaves continuously. Therefore, in Germany, Ginkgo biloba extract has been approved to treat symptoms of brain dysfunction, including memory disorder, drowsiness, tinnitus and headache.

Avoid peripheral arterial ischemia: cold limbs? Don't ignore the warning of peripheral blood circulation. Our tissues and organs can only function normally if we keep the blood flowing. Once ischemic, there will be various functional problems. This situation may occur in all parts of the human body. For example, it may lead to angina pectoris and myocardial ischemia, stroke, and peripheral arterial occlusion of limbs. In other words, cold limbs are a warning signal of poor peripheral blood circulation. In case of obstruction, ischemic pain, even intermittent claudication and even ischemic necrosis of limbs may occur. Clinically, it often happens that the elderly wear shoes, and there are things (such as stones) in the shoes but they can't feel them. It caused the foot muscle necrosis for too long, and finally it could only be amputated. These are all problems caused by peripheral blood circulation disorder. So how to prevent or improve peripheral blood circulation disorder? In addition to diet control, reducing blood viscosity and avoiding thrombosis, we should also develop fixed exercise habits to make blood circulation active and smooth, and at the same time strengthen peripheral blood circulation. In addition, Ginkgo biloba extract also has a good effect on improving peripheral blood circulation. Flavonoids, biflavonoids, ginkgolides and other substances contained in Ginkgo biloba leaves can activate platelets, avoid blood coagulation, reduce thrombosis, and at the same time improve blood flow speed and tissue blood supply, so that tissues or organs with poor blood supply can regain adequate blood supply, thereby improving tissue oxygen supply capacity and alleviating symptoms caused by local tissue ischemia or hypoxia. Numerous studies have shown that eating Ginkgo biloba leaves every day can effectively improve the walking distance. People with claudication symptoms can significantly improve their walking ability by eating Ginkgo biloba leaves extract at least120mg every day for 24 weeks. Improve premenstrual syndrome: After conditioning for 3 months, about 85% of women will have premenstrual physical and emotional discomfort, such as headache, pain, emotional anxiety, etc. Taking Ginkgo biloba extract will also help; A study on 143 18 to 45-year-old women showed that after taking 80 mg of Ginkgo biloba extract every day, the symptoms of pain and emotional anxiety were obviously relieved after two menstrual cycles. Improve vision, prevent glaucoma and macular degeneration: improve blood flow and protect optic nerve. Glaucoma is an optic atrophy disease caused by high intraocular pressure, which is one of the main causes of blindness in China. What patients are most worried about is the deterioration of visual field, which usually progresses slowly and unconsciously, especially normal-tension glaucoma (NTG). The patient's intraocular pressure was within the normal range, but the optic nerve gradually atrophied. Besides using eye drops to reduce intraocular pressure, it is also necessary. It is found that the visual field of glaucoma patients can be significantly improved after taking120mg Ginkgo biloba extract every day for eight weeks. One is twelve years? After three years of follow-up, the visual field of normal tension glaucoma was improved after oral administration of Ginkgo biloba extract. The results showed that 42 patients took Ginkgo biloba extract 80 mg orally twice a day, and there was no significant difference in intraocular pressure and visual field before and after treatment, which indicated that Ginkgo biloba extract could really improve the persistent visual field defect caused by normal intraocular pressure glaucoma. In addition to improving glaucoma, Ginkgo biloba leaves can also improve blood flow, promote cell metabolism, increase blood circulation of eyeball and brain, and also have preventive and therapeutic effects on macular disease, a vision killer. It is found that patients with macular disease can improve their eyesight after six months by taking 160 mg of Ginkgo biloba extract every day, and taking high dose (240 mg) every day is better than taking low dose (60 mg). Improve dizziness and tinnitus: inexplicably dizzy for a while? Please pay attention to peripheral blood circulation. Staring at the computer at work without rest. Internet cafes play video games online. After a long time, it is easy to get dizzy. At this time, they will feel dizzy and even vomit. But as long as they have a rest, they will be fine. Some people will also have tinnitus symptoms similar to sudden deafness (loud tinnitus). There are many possible reasons for dizziness. In addition to stroke, cardiovascular disease and psychogenic stress, the most common cause in clinic is poor peripheral blood circulation in the inner ear, especially in patients with diabetes, hypertension and hyperlipidemia, and eight out of ten people are caused by poor blood circulation. Dizziness and tinnitus caused by poor peripheral blood circulation are sometimes a precursor of "stroke" and can not be ignored. At this time, you can take Ginkgo biloba leaves to improve hemodynamics. A multicenter controlled study showed that 70 patients with dizziness and tinnitus due to poor peripheral blood circulation were treated with Ginkgo biloba extract and placebo for three months (twice a day, each time 160 mg), and 40% of the patients who took Ginkgo biloba extract could get meaningful improvement; In a small study published in the European Journal of Otolaryngology, 106 outpatients with primary sudden deafness were randomly divided into two groups. One group took 240 mg of Ginkgo biloba extract every day, and the other group took 120 mg every day. After eight weeks, the patients in both groups improved, and the patients taking high dose recovered significantly faster. Reduce free radical interference and avoid complications. In recent years, many studies have pointed out that the occurrence of diabetes is closely related to the role of free radicals. What is terrible about diabetes is not the symptoms of diabetes itself, but the complications it causes, such as nephropathy, retinopathy and neuropathy. Ginkgo biloba extract has antioxidant effect, which can protect the body from free radical interference and help to slow down the deterioration of diabetes. How to make good use of the natural health care function of Ginkgo biloba? Up to now, more than 660 related medical research reports have confirmed the clinical therapeutic effect of Ginkgo biloba preparation, which is also widely used in neurology, ophthalmology, otolaryngology, metabolism and other clinics, and is one of the drugs often used in large medical centers in China. However, there are many health foods made of Ginkgo biloba leaves on the market. Is ginkgo a medicine or a food? How to choose and use, in order to really play a role? Edible ginkgo biloba leaves? Ginkgo fruit? Be sure to find out whether ginkgo is medicine or food first. Basically, it will be different according to the extraction location of Ginkgo biloba leaves and the regulations of various countries. Ginkgo biloba leaves are really good for health, but the effects of Ginkgo biloba leaves extracts in different parts will be different; At present, Ginkgo biloba is mainly used for health care, including "Ginkgo biloba leaves" and "Ginkgo biloba fruits (seeds)". The former contains EGb76 1 and other components, which is medically proved to inhibit platelet coagulation and reduce thrombosis, thereby increasing blood flow speed and tissue blood supply, improving tissue oxygen supply capacity and relieving symptoms caused by local tissue ischemia or hypoxia; Ginkgo biloba, also known as ginkgo biloba, is mainly composed of albumin. Traditional Chinese medicine believes that it has the effects of astringing lung, benefiting qi, relieving asthma, contracting qi, dilating microvessels, promoting blood circulation and removing blood stasis, so it is often used as medicinal food. In other words, products containing Ginkgo biloba extract aim to improve peripheral blood circulation and prevent Alzheimer's disease. At present, Ginkgo biloba extract is listed as a drug management in Taiwan Province Province, and the approved indication is to improve peripheral blood circulation disorder, but in fact, Ginkgo biloba is listed as a functional food in many countries. It is more secure to choose products tested in Germany and the European Union. It is worth noting that the content of ginkgo products on the market is generally less than the marked value. 1999, the American consumer laboratory survey found that a quarter of ginkgo products did not meet the marked value, which rose sharply to 75% in 2003. Although it slowed down in 2007, there are still 4 1% products with insufficient ingredients. Besides, we should pay attention to the problem of pollution. Lead pollution has been detected in ginkgo products in the United States. Ginkgo is a plant and it is inevitable to use pesticides when planting. However, ginkgo products in most countries (including the United States) have not been tested for pesticides, which makes it more difficult to buy ginkgo. My suggestion is to choose products that have been tested by Germany and the European Union, because the regulations on the composition of Ginkgo biloba leaves in this area are much stricter than those in other areas, which is relatively safe. Ginkgo biloba leaves can promote blood circulation, which is not suitable for some people. If it is used for general daily health care, it is suggested that the intake of Ginkgo biloba leaves should be 100 mg per day. If you have brain diseases, you can strengthen the dose, and the dose within 240 mg is safe. However, because Ginkgo biloba leaves can promote blood circulation, it may have additive effect when combined with anticoagulant or aspirin, which makes the wound difficult to heal and bleed, increasing the risk of bleeding. Therefore, patients taking anticoagulants or aspirin should avoid supplementing Ginkgo biloba extract. In addition, patients with abnormal platelet function, hematological tumor diseases and pregnant women should not take Ginkgo biloba leaves, and the elderly, children, patients with gastric ulcer and duodenal ulcer should consult a doctor before taking them. In addition, Ginkgo biloba leaves and antihypertensive drugs may also have additive effects. It is recommended to discuss the dosage with the doctor before taking it. This article is excerpted from Eat Right Health Food 2 Nature: Dr. Jiang Shoushan teaches you to eat natural health products intelligently/Jiang Shoushan (a famous doctor of kidney disease)/Neo-naturalism ※ In the article, Liao Weicheng, a pharmacist who specializes in promoting blood circulation and preventing diseases of Ginkgo biloba, pointed out that in fact, the main functional components of Ginkgo biloba are ginkgo flavonoids (flavonoids) and ginkgolides A, B, C and M (diterpenoids). Flavonoids have antioxidant and free radical scavenging effects, thus protecting brain nerve cells from antioxidant stress and reducing nerve cell damage. Ginkgolide is an antagonist of platelet activating factor (PAF), which can inhibit platelet aggregation and prevent thrombosis. In addition, flavonoids can inhibit cyclooxygenase and lipoxygenase, increase blood fluidity, and thus improve peripheral blood circulation disorders (for example. Intermittent claudication) and poor cerebrovascular circulation. Simply put, Ginkgo biloba leaves can resist oxidation and promote blood circulation, but it is not helpful to reduce the concentration of common "neurotransmitters", so it has no improvement in international research. Perhaps it should be positioned as "Ginkgo biloba helps to prevent dementia in the elderly", but it may not be effective because it does not increase the concentration of acetylcholine. Ginkgo biloba often plays a preventive role. If you feel that your brain power has dropped, it is usually not effective to supplement it. And "the memory has not deteriorated, or the elderly who are often dizzy (but not anemic) because of poor blood circulation complain that their memory has been poor recently", probably because the blood circulation in the brain is not good, so it is more appropriate to eat Ginkgo biloba. Studies have shown that supplementing Ginkgo biloba leaves can indeed increase blood circulation in the brain.
