Health care function of Lycium barbarum.
Anti-aging and improving sleep: Anti-aging is one of the most important functions of Lycium barbarum. A large number of anthocyanins can resist oxidation and scavenge free radicals in human body, which has a significant anti-aging effect. Anthocyanins can cross the blood-brain barrier, protect the brain from oxidation, stabilize the function of brain tissue and protect the brain from harmful chemicals and toxins. Eating anthocyanins in Lycium barbarum can significantly improve sleep quality.
Beauty beauty, improve the skin: it can prevent the early generation of skin wrinkles and make the skin younger and more energetic. It can not only prevent the early generation of skin wrinkles, but also supplement nutrition and eliminate harmful free radicals in the body. Anthocyanin is a natural sunscreen, which can prevent ultraviolet rays from damaging the skin. If protected with anthocyanins, about 85% of skin cells can survive. [ 1]?
Nourishing kidney and essence, preventing cancer: black wolfberry can nourish kidney and essence as well as red wolfberry. Anthocyanins in Lycium barbarum L. can scavenge free radicals and prevent cancer cells from spreading smoothly, thus protecting more healthy cells from being eroded by cancer cells. For example, the pathogenesis of breast cancer is like this, so taking anthocyanins will have a good inhibitory effect on the development of breast cancer.
Protecting the liver and improving eyesight: Medical clinical reports show that anthocyanins in blueberries can promote the regeneration of Rho dopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision. Anthocyanins can improve eyesight in dim light, which is helpful for drivers at night and people who stare at the screen for a long time.
Improve circulation and strengthen physique: Anthocyanin can improve blood circulation, restore lost microvascular function, strengthen fragile blood vessels, and thus make blood vessels more elastic. Procyanidins are called "the antidote to atherosclerosis". For patients with venous insufficiency, proanthocyanidins can effectively relieve the symptoms such as pain, edema and nocturnal spasm, so doctors in Europe usually recommend patients with varicose veins to eat foods rich in anthocyanins.
Prevention and treatment of diabetes: Lycium barbarum can also prevent and treat diabetes, which has obvious effects of anti-fatigue, liver protection, anti-tumor, dredging blood vessels, lowering blood pressure and protecting cardiovascular system.

Value editing of Lycium barbarum
Tonify kidney and essence, nourish liver and improve eyesight, replenish blood and soothe nerves, promote fluid production to quench thirst, moisten lung and relieve cough, and treat yin deficiency of liver and kidney, soreness and weakness of waist and knees, dizziness, blurred vision, watery eyes, cough, thirst and nocturnal emission.
Lycium barbarum is a natural, wild and pollution-free pure medicinal material. Due to the development of modern agriculture, the nutritional quality of high-yield crops is declining, especially some minerals, vitamins and biological pigments in crops are reduced, which leads to people's nutritional imbalance, followed by the complications of "invisible hunger". In addition, long-term excessive application of chemical fertilizers, pesticides and growth regulators has made food nutritional safety a big problem.
Lycium barbarum is wild in plateau desert, and its growth is free from human intervention and pesticide pollution. It is a truly pure natural green food and a high-grade tonic for home consumption and gifts to relatives and friends.
Lycium barbarum is a natural cobalt supplement. Cobalt has low toxicity to human body, participates in the synthesis of vitamin B 12 and stimulates hematopoiesis. The content of cobalt in Lycium barbarum is much higher than that of green leafy vegetables by 0.2-0.6 ppm (dry weight), but it does not pose a toxic threat to human body. Lycium barbarum L. has the function of simple cobalt supplement medicine.
Lycium barbarum is a natural nickel tonic. Chromium and nickel are also essential trace elements for human body, but high content will cause poisoning. Chromium is closely related to glucose metabolism, lipid metabolism, protein synthesis and nucleic acid metabolism. The chromium content of rare brand Lycium barbarum is lower than that of ordinary milk (5 ~ 15ug/ml), so it will not cause poisoning to human body. Nickel, as a cofactor of biological ligands in human body, promotes the absorption of trivalent iron in intestine. The content of nickel in Lycium ruthenicum is higher than that in cereals, bacon and vegetables (0. 1 ~ 0.3 μ g/g), but it will not pose a toxic threat to human body within the concentration range, so Lycium ruthenicum has the function of simply supplementing nickel. [2]
Lead and cadmium are heavy metal pollution elements strictly controlled by environmental protection organizations, which are harmful to human body. The content of lead and cadmium in Lycium barbarum is much lower than that in common plants (0.5 ~ 3.0μ g/g).
Traditional Chinese medicine discusses the efficacy of Lycium barbarum: Lycium barbarum can nourish liver and kidney, benefit eyesight, and is suitable for soreness of waist and knees, dizziness and other diseases. According to Tibetan medical classics Four Medical Codes and Zhu Jing Materia Medica, Lycium barbarum is mainly used to treat heart heat, heart disease, irregular menstruation and menopause. According to the records of Uyghur medicine, the fruit and root bark of Lycium ruthenicum are commonly used by Uyghur medicine to treat diseases such as urethral calculi, scabies, gingival bleeding, etc., and are used as nourishing and antihypertensive drugs by the people. Modern scientific research has confirmed the above statement, and it is believed that Lycium barbarum has the functions of lowering cholesterol, exciting brain, enhancing immune function, preventing and treating cancer, resisting aging and beautifying. Lycium ruthenicum extract can promote cellular immune function, enhance lymphocyte proliferation and tumor necrosis factor production, has a two-way mediation effect on interleukin -2, and can relieve polydipsia and weight loss of diabetic patients.
Discussion on the efficacy of Lycium barbarum in modern medicine: Scientifically measuring the vitamin and fat content of Lycium barbarum is much higher than that of Lycium barbarum. Calcium, magnesium, copper, zinc, manganese, iron, lead, nickel, cadmium, cobalt, chromium, potassium and sodium play an important role in maintaining normal physiological functions of human body. Compared with red Lycium barbarum, the contents of iron, calcium, magnesium, zinc and copper in black Lycium barbarum are much higher than its average value, while the contents of potassium and manganese are far lower than its average value, and the contents of sodium are basically the same.

The edible value of Lycium barbarum.
Lycium ruthenicum [3]
According to media reports, Lycium barbarum is a wild plant growing on Golmud prairie in Qinghai, and it is an important vegetation for windbreak and sand fixation. However, from August, 20 15 to September, 20 17, more than 5,000 people flooded in and plundered more than 3 million mu of grassland, with the purpose of picking purple-black berries as big as beans, and profit-seeking became the biggest motivation.
According to reports, black wolfberry is called "soft gold". In recent years, the price of its origin has increased nearly 8 times, reaching nearly 500 yuan per kilogram. In Golmud, a place called "Golden Triangle" is the black wolfberry trading market. In a specialty store, the retail price of Lycium barbarum is divided into four grades, the lowest is per kilogram 1200 yuan, and the highest is 4,400 yuan. The reporter searched on a large online shopping platform and found that "wild black wolfberry" dried fruits with a price of two or three thousand yuan a catty abound, and the most expensive "boutique" sold for more than 4,000 yuan a catty.
Lycium barbarum is dark black, and the dried fruit is fragile, containing 5- 12 seeds. There are many large seeds, up to more than 30. Black Lycium barbarum seeds, like red Lycium barbarum seeds, are soaked in water with dark color and low sugar content, and the water is slightly sweet or even not sweet. If the dried fruit is soaked in water with high sweetness and the black wolfberry is treated with rock sugar, the appearance color of this black wolfberry is particularly gorgeous. Nitraria tangutorum is dark red and has no stem. When the fruit is ripe, the stalk will fall off automatically, and it is mononuclear (its biggest feature). It's hard to rub by hand. Nitraria tangutorum is light in water, high in sugar content and sweet in taste.
Wild Lycium barbarum L. is sweet in taste and flat in nature, and rich in protein, fat, sugar, free amino acids, organic acids, minerals, trace elements, alkaloids, vitamins C, B 1, B2, calcium, magnesium, copper, zinc, manganese, iron, lead, nickel, cadmium, cobalt, chromium, potassium and sodium. The contents of calcium, iron and nicotinic acid in Lycium barbarum are 2.3 times, 4.6 times and 16.7 times higher than those in Lycium barbarum, especially the content of proanthocyanidins is higher than that in blueberry (Lycium barbarum contains 3690 mg/100g; Blueberries contain proanthocyanidins 330 ~ 3380mg/ 100g). This is the natural wild fruit with the highest proanthocyanidins content found so far, and it is also the most effective natural antioxidant. Its efficacy is 20 times that of VC and 50 times that of VE. It is also rich in vitamins, minerals and other nutrients, especially natural anthocyanins with free radical scavenging and antioxidant functions. Its medicinal and health care value is much higher than that of ordinary Lycium barbarum, and it is called "soft gold".
Anthocyanin is a water-soluble pigment and a product of plant metabolism. Under different acidity and metal ions, it will absorb sunlight with different wavelengths, thus making plants appear red, blue, purple or even black.
Lycium ruthenicum [3]
In the normal life metabolism of human body, some oxygen free radicals will be produced in cells. Under the influence of some external factors, such as ultraviolet radiation and smoking, the number of free radicals in the body will increase. Free radicals can attack DNA, protein, fat and so on. Therefore, people think that free radicals in the body are the cause of aging and illness. Those substances that can scavenge free radicals or prevent oxidation reactions are called antioxidants. It is not a substance, but a general term for all kinds of substances with antioxidant capacity. For example, vitamins C, E, carotene, polyphenols and so on are antioxidants.
Anthocyanin is a powerful antioxidant, which can protect the human body from a harmful substance called free radicals. The free radical scavenging ability of anthocyanins is 50 times that of vitamin E and 20 times that of vitamin C. Anthocyanins can be absorbed by human body 100%. After taking it for 20 minutes, it can be detected in blood and maintained in the body for 27 hours. Different from other antioxidants, anthocyanins have the ability to cross the blood-brain barrier and directly protect the central nervous system of the brain. Anthocyanins can also enhance blood vessel elasticity, improve circulatory system and skin smoothness, inhibit inflammation and allergy, and improve joint flexibility.
The "efficacy" of Lycium barbarum mostly comes from its rich antioxidant effect of anthocyanins, and there is no direct clinical trial data. Cell experiments and animal experiments can give scientists some research directions, but they can't be regarded as "efficacy"
Evidence of. Although antioxidants can prevent or terminate other oxidation reactions, they may also be oxidized to produce harmful products. Another common reason is that an antioxidant shows a "health care function" in a simple system, but it also has other side effects in a complex environment in the body. Positive and negative balance, the result is hard to say.
Antioxidant damage of cells is related to the occurrence of many chronic diseases, such as cancer, aging and cardiovascular diseases. Because fruits and vegetables have a certain effect on reducing the risk of cancer, people naturally think that anthocyanin is not an effective component of cancer. Many people have studied this and published a large number of scientific papers. Generally speaking, anthocyanins have a strong inhibitory effect on cancer cells cultured in vitro. For experimental animals such as mice, anthocyanins also show some resistance to artificially induced tumors. However, whether it is effective for human body is lack of corresponding evidence. Italy has conducted some "case-control" studies, comparing the dietary status of thousands of cancer patients with similar but unaffected "control groups", and found no "effective components" in blue-purple vegetables such as anthocyanins related to cancer.
