Pharmacological action and efficacy of Ginkgo biloba
Ginkgo biloba is the oldest relict plant in the existing seed plants. After the glaciers in the fourth century, it became the initial unique tree species and has been known as the “living fossil” in academia.
Therefore, the people of the People’s Republic of China have always respected Ginkgo as “the holy tree” and “the god tree”.
At present, more than 160 effective pharmaceutical ingredients can be extracted from Ginkgo biloba.
Its main extracts have magical effects in cardiovascular disease, anti-aging, anti-aging, skin protection, anti-cancer, anti-bacterial, anti-allergic and self-improvement, and give high blood pressure, coronary heart disease and cerebrovascular disease that threaten human health.Build a natural barrier.
Therefore, ginkgo development has become popular in the world, and ginkgo fever has emerged around the world. For example, Ginkgo biloba extract has been listed as a special blood pressure lowering drug and natural medicine in France and Germany; it has been listed as an anti-aging and special treatment for Alzheimer’s disease in Japan.
The State Science and Technology Commission also included the research and development of Ginkgo into the national key projects of the “Eighth Five-Year Plan” and “Ninth Five-Year Plan”.
A number of recent studies have focused on a class of alcohol-soluble diols, the most important of which are ginkgolides and bilobalides.
These ingredients, which are only found in ginkgo, have a significant effect on increasing blood circulation in the brain, reducing blood viscosity, and reducing vascular damage during inflammation.
Chemical composition and pharmacological action of Ginkgo biloba: The chemical constituents of Ginkgo biloba: mainly flavonoids and xylene lactones, mainly derived from natural pigment compounds containing sugars in leaves (Ginkgo biloba leaves turn golden yellow in autumn, so with yellow”preliminary).
The flavonoids of Ginkgo biloba are mainly quercetin compounds, kaempferol compounds and flavonoids. The flavonoids in Ginkgo biloba are ginkgo bisflavonoids, iso-ginkgo bisflavonoids and 7-demethyl ginkgo bisflavonoids.Ginkgo biloba has a major contribution to the antioxidant and scavenging free radical action.
The most important extracts of ginkgo are ginkgolides and flavonols.
Ginkgolide has an anti-platelet activating factor that improves blood circulation.
Flavonols can dilate blood vessels, eliminate free radicals, and prevent arteriosclerosis.
In addition, Ginkgo biloba extract can also eliminate free radicals in the human body, improve the body’s own immunity, prevent age spots, skin care, beauty, and shiny skin.
Pharmacological effects of Ginkgo biloba: platelet aggregation and hemostasis; effects on myocardial function and myocardial infarction; effects on blood vessels; protective effects on the brain; effects on the ears and eyes; anti-inflammatory effects; anti-allergic effects; anti-shock effects;; anti-tumor effect; anti-pollution of harmful substances; the role of the reproductive system; protection of organ transplant response; the role of the digestive system; the role of the urinary system.
Ginkgo’s medical and health benefits Ginkgo and blood circulation: Ginkgo can promote blood circulation in the brain and extremities. Ginkgo can protect arteries, veins and capillary damage, and enhance its strength and elasticity.
In addition, Ginkgo can directly promote blood circulation by reducing the viscosity of platelets (a key factor in the formation of arteriosclerosis), protecting local damage of red blood cells and keeping them evenly distributed.
This means that oxygen can be transported to the body’s tissues more healthily and efficiently.
Ginkgo biloba and free radicals: Ginkgo biloba is one of the herbs with anti-active genes. Ginkgo biloba is very effective in protecting lipids (components of cell membranes) from free radical damage.
Considering that brain cells contain the highest concentration of unsaturated fatty acids in all cells, this strongly supports the protective effect of ginkgo on the central nervous system.
Free radicals in the brain and nervous system are widely recognized as the primary means of accelerating aging.
Ginkgo plays multiple roles in protecting cells, especially brain cells.
First, it promotes blood circulation and the delivery of oxygen and glucose to the cells. Second, when free radicals threaten cells, Ginkgo can protect cells from damage and then free radicals are eliminated from the body.
Ginkgo and platelets: Over the past five years, research on ginkgolides has led to a breakthrough in drugs.
Three ginkgolides (A, B and C) have been shown to inhibit the action of a mediator called platelet activating factor (PAF) in the body.
PAF can cause high blood pressure, shock, bronchoconstriction, gastric ulcer, high blood pressure, vasculitis and other diseases.
