Research: Wolfberry And Ginkgo Biloba Can Relieve Visual Fatigue

With the continuous development of technology, electronic products have become an indispensable product in our lives, which has led to the phenomenon of eye fatigue in many people. In Chinese medicine, the function of "seeing" eyes depends on the nourishment of liver blood, which is stored in the liver and regulated and regulated by the liver. Nourish the eyes first and nourish the liver. When you feel dry eyes, astringent eyes, eye pain and other symptoms of visual fatigue, you need to clear the liver to clear your eyes.

Wolfberry

The Solanaceae wolfberry is a mature fruit of the wolfberry of the Solanaceae plant. It is a tonic Chinese medicine. There are about 80 kinds of wolfberry in the world. The quality of wolfberry in China is the best in Ningxia.

The chemical composition of wolfberry mainly includes sugar, amino acids, trace elements, carotene, vitamin A, B1, B2, C and other essential nutrients for healthy eyes.

Vitamin A

Wolfberry is rich in vitamin A and carotene. Carotene can be converted into vitamin A in the body. Vitamin A is also known as retinol or anti-dry eye factor. It is a component of rhodopsin that constitutes weak light in visual cells. Maintaining normal visual function has an important role, can prevent night blindness and vision loss, and help to treat a variety of eye diseases.

Zeaxanthin

Wolfberry is rich in zeaxanthin. Zeaxanthin is an oxygen-containing natural carotenoid. It is an isomer with lutein. Zeaxanthin is important to prevent ultraviolet rays from damaging the optic nerve of the eye Ingredients, however, the human body can not produce zeaxanthin, only by drawing from food, ingesting wolfberry is an important guarantee for supplementing zeaxanthin in the human body.

Taurine

Goji berries contain 19 amino acids, including 8 essential amino acids, with a total amount of 9.14%. At the same time, it is also found that it contains taurine, which is the only plant body reported to contain taurine, with a content of 0.205%- 0.689%. Taurine is a sulfur-containing amino acid with a simple structure. It exists in the free form in the retina, but does not participate in protein synthesis. In vivo, a decrease in the concentration of taurine in the retina will lead to the destruction of the photoreceptor structure, accompanied by severe visual dysfunction and abnormal electroretinogram. Taurine at a physiological level in the retina plays an important role in maintaining the structure and function of visual cells.

Ginkgo biloba

Ginkgo biloba is of high medicinal value. Its chemical components are mainly flavonoid glycosides, terpene lactones, polyprenyl alcohols, organic acids, ginkgo phenolic acids and alkylphenols, alkylphenolic acids, Ginkgo acid, etc., vitamin C, vitamin E, carotene and calcium, phosphorus, boron, selenium and other mineral elements are also very rich in content, more than ordinary fruits and vegetables and edible plant raw materials.

Chinese medicine believes that Ginkgo biloba is sweet, bitter, astringent, flat, and has the effects of constricting lungs and asthma, promoting blood circulation and removing blood stasis. As the researchers further studied their pharmacological effects, they discovered that Ginkgo biloba has a very good effect on alleviating visual fatigue. Studies have shown that Ginkgo biloba has the following effects in improving patients' vision:

1. Inhibit platelet aggregation

The lactones contained in Ginkgo biloba can inhibit a substance called platelet activating factor, so Ginkgo biloba can reduce blood viscosity, inhibit platelet aggregation, increase arteriolar elasticity, increase vascular permeability, and thus increase retinal transparency.

Dilate blood vessels. Ginkgo biloba can play a role in relaxing blood vessels by increasing the calcium ion concentration of vascular endothelial cells, increasing nitric oxide synthase activity, and then increasing nitric oxide production, and also can play a role in relaxing blood vessels by increasing PGI2 and decreasing TXA2. The leaf in the retina can dilate microvessels, reduce retinal vascular tone, and inhibit microthrombosis, thereby improving the patient's visual function.

2 Optic nerve protection

Ginkgo biloba can increase blood supply to the choroid and retina, thereby improving visual function. The medical community generally believes that during normal physiological activities of the eye, it is necessary to constantly overcome the resistance to fluctuations in intraocular pressure in order to regulate the blood flow velocity of the optic nerve. Ginkgo biloba can improve central and peripheral blood flow, reset vasospasm and reduce apoptosis; Ginkgo biloba has the effect of inhibiting glutamate toxicity, thereby slowing the apoptosis of nodal cells; Ginkgo biloba's natural antioxidant activity can effectively protect mitochondria Function, protect against tissue and cell damage caused by different reasons, thereby protecting the integrity of mitochondrial structure and function. Ginkgo biloba protects retinal ganglion cells by changing eye microcirculation, protecting optic neurons, and protecting mitochondria.

In summary, ginkgo biloba and wolfberry are rich in a variety of nutrients that are beneficial to the eyes. Especially in mitigating visual fatigue, it is a very good choice to jointly develop Ginkgo biloba and wolfberry to alleviate visual fatigue products
