Ginkgo biloba is a precious tree species unique to China, and it is the oldest gymnosperm left over from the 4th century glacier movement. At the end of the Han Dynasty and the Three Kingdoms, Ginkgo biloba was planted in the south of the Yangtze River, and then it was widely planted all over the country. From the end of 17, some European and American countries began to introduce ginkgo trees. Modern science has proved that ginkgo flavone extracted from ginkgo orchards is one of the most effective components for preventing and treating hyperlipidemia and cardiovascular and cerebrovascular diseases. The development of ginkgo products is of great significance to human health. Ginkgo products have developed from tea and tablets to soft capsules. The following is my understanding of the medicinal value of Ginkgo biloba. Welcome to read.

Medicinal value of Ginkgo biloba extract

1. dilate blood vessels and protect vascular endothelial tissue;

2. Regulating blood lipid;

3. Protect low-density lipoprotein;

4. Improve hemorheology;

5. Inhibit PAF (platelet activating factor) and inhibit thrombosis;

6. improve memory;

7. Scavenging free radicals;

8. Anti-hypoxia effect;

9. Prevent arterial spasm.

Ginkgo biloba is the leaf of Ginkgo biloba, also called Ginkgo biloba. According to "Dietotherapy Materia Medica", Ginkgo biloba can be used for palpitation, lung deficiency and cough and asthma. In 1960s, the research on Ginkgo biloba leaves began in West Germany. They found that the effective components of Ginkgo biloba leaves, mainly flavonoids, have the functions of protecting capillary permeability, dilating coronary arteries, restoring arterial elasticity, nourishing brain cells and other organs, and also have the peculiar function of maintaining normal blood quality and cholesterol levels in arteries, peripheral vessels and capillaries.

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 its excellent pharmacological effects are gradually recognized by people.

Clinical observation proves that Ginkgo biloba leaves have the following functions.

1, reducing the level of cholesterol in human blood and preventing arteriosclerosis. Can be used for improving symptoms such as physical fatigue, rapid heartbeat, chest pain, dizziness and the like of middle-aged and elderly people after slight activities.

2. Lowering blood pressure by increasing vascular permeability and elasticity has a good antihypertensive effect.

3. Eliminate the deposited components on the blood vessel wall, improve the blood flow change, enhance the deformability of red blood cells, reduce the blood viscosity, and make the blood flow unobstructed, which can prevent and treat cerebral hemorrhage and cerebral infarction. It also has certain curative effect on senile dementia caused by arteriosclerosis.

4. Ginkgo biloba preparation combined with hypoglycemic agents has a good effect on diabetes, and can be used as an auxiliary drug for diabetes.

5, can significantly reduce menstrual abdominal pain and backache and other symptoms.

6, used to treat bronchial asthma, also has a good effect.

7, reduce the level of lipid peroxidation, reduce freckles, moisturize the skin, beautiful appearance.

Medicinal value of ginkgo biloba

The medicinal use of Ginkgo biloba is mainly reflected in three aspects: medicine, pesticide and veterinary medicine. In the Ming Dynasty, Li Shizhen once said: "Entering the lung meridian can benefit the temper, relieve asthma and cough, and reduce defecation." In Ben Feng Jing Yuan, written by Zhang Lulu in Qing Dynasty, Ginkgo biloba has the functions of resolving phlegm, detoxicating and killing insects, and can be used to treat "scabies, carbuncle, dental caries, infantile diarrhea, leucorrhea with red and white discharge, prolonged stranguria, nocturnal emission and enuresis". In the Ming Dynasty, Chinese patent medicines made of Ginkgo biloba leaves appeared in Jiangsu, Sichuan and other places for clinical use. Ginkgo biloba exocarp contains a lot of hydrogenated ginkgolic acid and ginkgetin. The water-soluble components of exocarp have good antitussive and expectorant effects, and their properties are similar to those of cyclophosphamide and misoprostol. The effective rate of epicarp alcohol intermediate in inhibiting 22 common clinical pathogenic fungi was 865438 0%. 0. 1% hydrogenated ginkgolic acid inhibited 25 clinical pathogenic fungi with an effective rate of 92%. In addition, the inhibition rate of epicarp extract on apple anthracnose and other 1 1 plant pathogens reached 88%- 100%. The control rate of ethanol extract on geometrid reached 100% within 3 days, and it also had control effects on Tetranychus urticae, Myzus persicae, Chilo suppressalis and other pests. According to Compendium of Herbal Medicine of Folk Veterinary Medicine, Ginkgo preparation can treat strain of livestock, nasal congestion, lung abscess, cough due to lung deficiency, blood drop in urine, leucorrhea of female livestock, etc. Dingchuan decoction developed by Shandong Animal Husbandry Medical Station is used to treat infectious laryngotracheitis in chickens, and the cure rate is 95%.

Up to now, there are more than 60 kinds of Ginkgo biloba extract with known chemical components/kloc-0. There are mainly flavonoids, terpenoids, phenols, alkaloids, polyisoprene, quinic acid, linoleic acid, python oxalic acid, ascorbic acid, α-hexenal, bilobanol, bilobanone and so on. In 1960s, the Institute of Botany, Chinese Academy of Sciences and other units developed Shuxuening injection with Ginkgo biloba leaves, which has certain curative effects on coronary heart disease, angina pectoris and cerebrovascular diseases. At present, there are more than 50 kinds of skin care and hair care products prepared with Ginkgo biloba extract. In addition, ginkgo beverage, ginkgo peach juice, ginkgo beer, ginkgo tea and other health products developed from ginkgo leaves have been circulated in the market and achieved good results. At the same time, Ginkgo biloba leaves can also be used as pesticides. 1kg leaves add 20kg water, boil for 30min, and then soak for 2-3 days. The control rate of spiders and Pieris rapae is over 90%, and there is no residue.

Ginkgo biloba contains a variety of nutritional elements, besides starch, protein, fat and sugar, it also contains trace elements such as vitamin C, riboflavin, carotene, calcium, phosphorus, iron, potassium and magnesium, as well as ginkgolic acid, ginkgolic acid, pentosan and sterol. It has the dietotherapy and medical effects of benefiting lung qi, treating cough and asthma, stopping parasites, reducing stool, smoothing wrinkles, protecting blood vessels and increasing blood flow. Modern medical research shows that Ginkgo biloba also has the functions of dredging blood vessels, improving brain function, delaying brain aging of the elderly, enhancing memory ability, and treating Alzheimer's disease and cerebral blood supply insufficiency. The anti-aging ability of Ginkgo biloba leaves has great scientific influence in Germany and France. In addition, Ginkgo biloba leaves can also protect the liver, reduce arrhythmia and prevent fatal bronchoconstriction in allergic reactions, and can also be used to deal with asthma, transplant rejection, myocardial infarction, stroke, organ protection and dialysis.

Edible

Keep healthy and prolong life. Ginkgo biloba was listed as a royal tribute in ancient times. Japanese people have the habit of eating ginkgo every day. Westerners must eat ginkgo at Christmas. As far as eating methods are concerned, Ginkgo biloba mainly includes fried food, barbecue food, cooked food, side dishes, cakes, candied fruit, canned food, beverages and alcohol. However, it should be noted that improper dosage and eating method of ginkgo can cause poisoning. (mainly refers to the situation of overeating)

In order to prevent ginkgo poisoning, eating less cooked food is the fundamental method. If eaten raw, adults should take 5-7 capsules (with shell coating), and children should take 2-5 capsules each time according to their age and weight, and they can take it again after 4 hours. When eaten raw, it is best to remove the shell, red soft film and heart (germ). It is advisable to take 20-30 pieces of cooked food at a time, such as shelling, removing red soft film and removing embryo for cooking, even if the dosage is large, poisoning will not occur.
