Question 1: What are the advantages of Ginkgo biloba leaves in making tea? It is toxic to make tea directly from Ginkgo biloba leaves. Around us, more and more people have joined the ranks of "Ginkgo health care", and some old people directly pick leaves from ginkgo trees to make tea. So what is the role of ginkgo biloba? Can Ginkgo biloba leaves picked from trees be used directly? Ginkgo biloba is an ancient plant. Its leaves, fruits and roots are rich in flavonoids, phenols, alkaloids, linoleic acid and other chemical components, which have high medicinal value. Specifically, it is manifested in the prevention and treatment of Alzheimer's disease and the prevention of stroke. With the increase of age, the ability of oxygen-containing blood in the human body to pass through tiny capillaries in the brain gradually decreases, which is a condition of insufficient blood supply to the brain. There are many symptoms, such as decreased attention and short-term memory, depression, anxiety, dizziness and tinnitus. Ginkgo biloba can dilate blood vessels, reduce blood viscosity, improve blood circulation, increase the supply of brain tissue oxidation and nutrition, improve the speed of brain processing information, and enhance memory function, prevent Alzheimer's disease, prevent cerebral thrombosis and reduce the occurrence of stroke. Protect the heart and prevent atherosclerosis. A thick yellow waxy substance called plaque will be formed on the blood vessel wall of middle-aged and elderly people. It will gradually increase and block blood flow. If the blood flow to the heart itself is blocked, angina pectoris and myocardial infarction will occur, which is coronary heart disease. Flavonoids contained in Ginkgo biloba leaves are powerful antioxidants, which can help clear the garbage in blood vessels, reduce the content of density protein and prevent the occurrence of coronary heart disease. Studies on hearing and vision protection have found that Ginkgo biloba extract can increase the blood flow to the ears, and has certain curative effects on deafness and otogenic vertigo caused by various reasons. With the increase of age, the function of the macula on the retina decreases, resulting in decreased vision. Ginkgo biloba is an effective antioxidant, which can delay macular degeneration and protect vision. Anti-allergic, treatment of hemorrhoids Some elderly people are allergic to pollen and dust, showing symptoms of allergic rhinitis such as runny nose and sneezing, which can cause asthma in severe cases. Appropriate administration of Ginkgo biloba preparation can reduce the occurrence of allergies. In addition, most older people have hemorrhoids, and Ginkgo biloba can strengthen blood vessels and reduce varicose veins and hemorrhoids. Although ginkgo has many benefits, don't pick ginkgo leaves and fruits without authorization. Compared with the regular ginkgo preparation, the effect of making tea with several leaves is different. Moreover, different people need different doses for different diseases, and excessive doses will cause adverse reactions such as stomach pain and headache. Maybe you don't believe it. Ginkgo biloba leaves can be boiled in water for half an hour, then soaked for 2 ~ 3 days. If the concentration is high, it can also be used as a pesticide to control red spider and cabbage caterpillar! It can be seen that Ginkgo biloba leaves are toxic before treatment. There are many ginkgo preparations, including oral liquid, capsules, injections and tablets, as well as drinks, alcohol, bottled ginkgo health water and health tea.

Question 2: What are the benefits of Ginkgo biloba as tea? Ginkgo biloba extract is extracted and refined from the leaves of natural plant Ginkgo biloba by advanced extraction technology. The extract mainly contains flavonoid glycosides and ginkgolides, of which total flavonoids >: 24%, ginkgolide > 6%。 The extract has the following pharmacological effects: 1. Scavenging free radicals and inhibiting lipid peroxidation of cell membrane. 2. Antagonize platelet aggregation and microthrombosis caused by platelet platelet platelet platelet activation. 3. Change hemorheology, reduce blood viscosity and improve microcirculation disturbance. 4. It can improve and promote brain blood circulation and brain cell metabolism. Clinical studies show that various preparations made from the extract have remarkable curative effects on preventing and treating coronary heart disease, angina pectoris, myocardial infarction, cerebral embolism, cerebral vasospasm, sequelae of brain injury, senile dementia and mental retardation. At the same time, the extract can be used as an additive for food, cosmetics, etc. Ginkgo biloba leaves are the leaves of Ginkgo biloba of Ginkgo family. Ginkgo biloba leaves are sweet, bitter and flat, which is beneficial to the heart and lungs, eliminating dampness and stopping diarrhea. Records of Traditional Chinese Medicine record that it can "astringe lung qi, relieve asthma and cough, and stop turbidity". According to modern pharmacological research, Ginkgo biloba leaves have a wide range of effects on human and animals, such as improving cardiovascular and peripheral vascular circulation, improving myocardial ischemia, promoting memory and improving brain function. In addition, it can also reduce blood viscosity and scavenge free radicals. Ginkgo biloba preparation generally has mild side effects, such as dizziness, headache, fatigue, dry mouth, dry tongue, chest tightness, stomach upset, loss of appetite, abdominal distension, constipation, diarrhea, etc. It should be taken under the guidance of a doctor. As for taking Ginkgo biloba leaves by yourself, we should pay attention to the following points. First, we should consider whether we have indications or not, and do not take Ginkgo biloba leaves as general supplements. Secondly, we should pay attention to the quality of Ginkgo biloba leaves, whether there is mildew or pollution. Moreover, do not use too much, generally 5-6 grams is appropriate, and you can take it by decocting or boiling water, but it is not suitable for long-term continuous use. People with a history of allergies should use it with caution.

Question 3: What is the function of soaking ginkgo leaves in water? It is toxic to make tea directly from ginkgo leaves.

Question 7: What is the function of Ginkgo biloba leaves? Ginkgo biloba leaves are the leaves of Ginkgo biloba, also known as ginkgo leaves. According to "Dietotherapy Materia Medica", Ginkgo biloba leaves can be used for palpitation, lung deficiency and cough and asthma. Modern scientific research has proved that Ginkgo biloba leaves contain more than 200 kinds of medicinal ingredients, including 46 kinds of flavonoids, 25 kinds of trace elements and 8 kinds of amino acids. Among them, flavonoids are the main effective components, which have the functions of protecting capillary permeability, dilating coronary artery, restoring arterial elasticity, reducing serum cholesterol, increasing coronary blood flow, improving cardiovascular and cerebrovascular circulation, relieving smooth muscle spasm, relaxing bronchi, inhibiting bacteria, nourishing brain cells and other organs, and also have the peculiar effect of maintaining normal levels of blood quality and cholesterol in arteries, peripheral vessels and capillaries.

Ginkgo biloba leaves are also rich in VC, VE, carotene, calcium, phosphorus, boron, selenium and other mineral elements, which are more than ordinary fruits and vegetables and edible plant raw materials. Biological antioxidants are a kind of substances with direct and indirect antioxidant function in the body. Ginkgo biloba leaves contain two kinds of antioxidants-nutritional antioxidants and non-nutritional antioxidants. The former mainly contains carotene, VC, VE, selenium, zinc, copper, etc., while the latter mainly contains ginkgo flavonoids, terpene lactones, catechins, polyphenols, etc., which are also very rich in content, and they play an important role in protecting the body from oxidative damage caused by free radicals. Therefore, Ginkgo biloba leaves have the functions of nutrition, health care and treatment as a whole, and it is of great significance to develop and utilize Ginkgo biloba leaves as a resource with high nutritional and health care functions, which is of great significance to improve the comprehensive utilization rate of Ginkgo biloba leaves.

Development and Utilization of Ginkgo Biloba Since 1930s, Japan and West Germany began to study Ginkgo Biloba. With the deepening of modern pharmacological research, it is found that Ginkgo biloba leaves not only contain flavonoids, but also terpenoids, phenols and other compounds, and their excellent pharmacological effects have been gradually recognized.

Question 8: What is the efficacy and function of Ginkgo biloba leaves? Do you have any side effects when you drink too much? The effects of Ginkgo biloba leaves are: astringing lung, relieving asthma, promoting blood circulation to remove blood stasis and relieving pain. Used for cough and asthma due to lung deficiency; Coronary heart disease, angina pectoris, hyperlipidemia, anticoagulation, there is a certain probability to improve memory.

In recent years, more and more people use ginkgo biloba leaves to soak in water to prevent and treat hypertension and heart disease. Actually this is unscientific. Because:

1, Ginkgo biloba leaves contain a lot of ginkgolic acid, which is toxic. Generally, the leaves bought have not been deeply processed and extracted, and the ginkgolic acid content in them is as high as 3000-4000ppm, especially the ginkgolic acid is water-soluble. Not only can you not eat the effective substances such as ginkgo brass and ginkgolic acid in it after soaking in water, but the effect is the opposite, and it is full of poison!

2. Flavonoids, the main component of Ginkgo biloba leaves, are powerful platelet activating factor inhibitors. Long-term administration may inhibit platelet aggregation function and correspondingly increase the risk of cerebral hemorrhage. Therefore, the elderly should stop taking ginkgo leaves, and pay attention to the regular detection of blood coagulation, and do not blindly take them for a long time. For patients with senile vascular sclerosis and brittle blood vessels, it should not be taken for a long time to avoid cerebral hemorrhage.

3. Its side effects are great. If you eat too much, you will be poisoned, causing muscle convulsions and dilated pupils.

4. According to Chinese medicine, Ginkgo biloba leaves are forbidden for those who are evil. Ginkgo biloba leaves can promote blood circulation and prevent cardiovascular diseases, but other cardiovascular drugs (such as aspirin) cannot be taken at the same time.

Question 9: What are the benefits of drinking ginkgo tea? Ginkgo tea is produced by using the leaves of ginkgo trees and adopting advanced technology. It is rich in protein, amino acids, minerals and vitamins. Regular drinking can enhance human physical strength and improve immune function. Ginkgo tea has a good therapeutic effect on cardiovascular diseases, which is antithrombotic, helpful to prevent arteriosclerosis, protect blood vessels, prevent and treat coronary heart disease, and has protective effects on heart, brain, liver and kidney. It also has the effects of reducing serum cholesterol content, dilating blood vessels, improving blood circulation of heart and brain, increasing blood flow of peripheral blood vessels, promoting the proliferation of hematopoietic stem cells, relieving spasm and lowering blood pressure.

Ginkgo tea has important medicinal value. Up to now, there are more than 200 kinds of Ginkgo biloba extract whose chemical components are known. There are mainly flavonoids, terpenoids, phenols, alkaloids, polyisoprene, quinic acid, linoleic acid, python oxalic acid, ascorbic acid, a- hexenal, bilobanol, bilobanone and so on. Among them, theaflavin is the main component, and the content of four kinds of biflavonoids (theaflavin, ginkgetin, isoginkgetin and ginkgetin) in the crude extract of Ginkgo biloba leaves is the highest (August-September). Autumn leaves are 17.2mg/g, and summer leaves are 4.4 mg/g. In 1960s, Institute of Botany, Chinese Academy of Sciences and other units developed Shuxuening injection with Ginkgo biloba leaves, which has certain curative effect on coronary heart disease, hypertension, hyperlipidemia, angina pectoris and cerebrovascular diseases. Health care function 1, prevention of stroke risk factors, including hypertension, arteriosclerosis, heart disease and diabetes. Ginkgo biloba can inhibit the production of a substance called platelet activating factor (RSF) in human body. RSF affects the blood flow in arteries, reduces the blood flow to the brain, and leads to hypoxia in brain cells. Many studies have shown that Ginkgo biloba can greatly increase the blood flow to the brain and accelerate the recovery after stroke. Scientists inserted a silk thread into the carotid artery of rabbits to imitate human arteriosclerosis, and then injected Ginkgo biloba extract into a group of rabbits. The thrombus of rabbits injected with Ginkgo biloba extract was significantly smaller. 2. Improving the blood supply to the brain Carotid artery is the main channel for blood transfusion to the brain. When ginkgo biloba extract is injected into animals, the blood flow of carotid artery increases and the brain gets more blood. 3. Anti-myocardial ischemia Scientists ligate the coronary arteries of dogs to imitate human myocardial infarction. When Ginkgo biloba extract is injected into animals with myocardial damage, abnormal electrocardiogram will improve. 4, regulating blood lipids Ginkgo biloba is helpful for blood dilution, inhibiting thrombosis, improving blood circulation, and has no side effects. Therefore, Dr. Mander in the United States called Ginkgo biloba a "very creative" drug. 5, regulating blood pressure Ginkgo biloba can strengthen arteriosclerosis, veins and capillaries, but also strengthen the resistance of peripheral blood vessels, eliminate congestion, prevent various obstacles in internal organs, and promote normal function. These effects have been confirmed by many animal experiments, and clinical experiments in major hospitals can also prove that Ginkgo biloba is very suitable for patients with hypertension. 6, improve diabetes In German or French hospitals, after giving ginkgo biloba preparation to diabetic patients, it is found that more than 95% of patients have achieved significant improvement, and the blood sugar in the blood has been significantly reduced, which can reduce the amount of insulin injection, and has effect on capillaries, obviously improving the symptoms of diabetic patients. 7. Prevention of atherosclerosis Ginkgo biloba leaves can strengthen cerebral arteries or peripheral blood vessels, restore the elasticity of hardened blood vessels, promote the normal diameter of blood vessels, reduce cholesterol in the blood and prevent atherosclerosis, with excellent functions. 8. Protect the heart from free radical oxidation of LDL to produce lipid particles. A large number of lipid particles are combined with each other and deposited on the intima of blood vessels. Coronary arteries are blocked by the deposited LDL, and the heart can't get enough oxygen supply, which leads to a heart attack. Ginkgo biloba leaves can effectively improve blood circulation, ensure oxygen supply to the myocardium, and improve left ventricular hypertrophy, thus avoiding the occurrence of heart disease. 9. Prevention of Alzheimer's disease Ginkgo biloba can promote the strength of cerebral arteries or peripheral blood vessels, restore the elasticity of hardened blood vessels and improve narrowed blood vessels, thus reviving atrophied brain cells, preventing Alzheimer's disease, improving memory and reducing dizziness. 10, improve frequent micturition. Whether it is renal weakness or chronic renal failure caused by age, [1] Ginkgo biloba can be used for treatment. It can promote the normalization of capillaries, smooth blood circulation and improve the function of kidney and bladder. 1 1, liver protection If you take Ginkgo biloba leaves regularly, it can promote the full play of liver function. 12, other functions Spring has come, and a DIY ginkgo tea is prepared for everyone to entertain themselves and explore the production of ginkgo tea, and fresh pine branches can also be added (... > >
