Black Lycium barbarum is more nutritious than red Lycium barbarum, and it is rich in anthocyanins that red Lycium barbarum does not have. Lycium barbarum contains 17 kinds of amino acids and 13 kinds of trace elements, among which 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, and protein, fat, sugar, free amino acids, organic acids, minerals and trace elements. Black Lycium barbarum also has the functions of strengthening the brain and enhancing people's learning and memory ability.
Lycium barbarum is distributed in alpine sand forest, salinized sand land, along rivers and lakes, and in dry river beds. It is a unique desert medicinal plant species in western China, mainly produced in eastern Qinghai and scattered in northern Xinjiang, western Inner Mongolia, northwestern Shaanxi, Gansu and Tibet.
Lycium barbarum can be chewed directly, soaked in water or wine, and the eating effect is good. Eating directly can absorb the nutrients in Lycium barbarum to the greatest extent, and the anthocyanins in Lycium barbarum are water-soluble and the effect of soaking in water is also very good.
Its greatest function is its anti-aging effect.
Main efficacy
1, beauty beauty delays aging.
Anthocyanin in Lycium barbarum is the most effective antioxidant in nature at present, and its antioxidant activity is 50 times that of vitamin E and 20 times that of vitamin C. Regular consumption of Lycium barbarum can well resist the external oxidation of cells, remove the accumulation and precipitation of harmful free radicals in skin, protect collagen, make skin fresh and elastic, reduce wrinkles and delay aging. Lycium barbarum is called "oral skin cosmetics" and "natural anti-aging artifact".
2. Keep fit and enhance immunity.
Lycium barbarum L., known as "nourishing soft gold", is rich in protein, fat, sugar, free amino acids, organic acids, minerals, trace elements, alkaloids, vitamins and 100 kinds of essential nutrients. Regular consumption can nourish and strengthen the body, enhance immunity and strengthen the body. Moreover, the trace element zinc in Lycium barbarum can improve the activity of enzymes and increase the secretion of pituitary gonadotropin and growth hormone, thus treating kidney deficiency and improving sexual function.
3. Strengthen blood vessels to prevent cancer
Medical research shows that anthocyanins can improve blood circulation, restore lost microvascular efficacy and strengthen fragile blood vessels, which is called "the antidote for arteries". Therefore, doctors in Europe usually advise patients with hypertension and cardiovascular diseases to eat foods rich in anthocyanins. Moreover, anthocyanins in Lycium barbarum can prevent cancer cells from spreading smoothly, thus protecting healthy cells from cancer cells.
4. Replenish blood and soothe the nerves to promote sleep
Lycium barbarum L. is known as the "king of anthocyanins". Anthocyanins can penetrate deep into cells to protect cell membranes from free radical oxidation, and at the same time cross the blood-brain barrier to protect brain nerves from oxidation, thus stabilizing brain tissue and protecting the brain from harmful chemicals and toxins. Eating Lycium barbarum regularly can effectively improve sleep conditions and improve sleep quality.
5. Protect your eyes and improve your eyesight.
Medical clinical reports show that anthocyanins can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision. France has been using anthocyanins to treat eye diseases for many years. Experiments show that anthocyanins can improve 98% of computer vision fatigue, and have a good health care effect on adolescent pseudomyopia, dizziness, visual fatigue and dry eye in middle-aged and elderly people.
6. Natural sun protection and radiation protection
After radiation, the human body will produce endogenous free radicals, causing lipid peroxidation and other damage. The polyhydroxy structure of anthocyanins in Lycium barbarum has a strong effect of scavenging free radicals, thus inhibiting oxidative damage and improving skin resistance, immunity and radiation resistance. Moreover, anthocyanin is a natural sunscreen, which can effectively prevent ultraviolet rays from damaging the skin.
Black Lycium barbarum can be chewed directly or soaked in water or wine.
Edible method
1, soaking in water: (the water temperature is lower than 60 degrees), about 5 grams a day is more suitable for adults, and it can be adjusted according to its own situation or eaten dry.
2, soaking wine: you can drink it immediately, but it is best to soak it for a month, so the effect is better.
3, cooking soup: use chicken, duck, ribs and other cooking soup. It can tonify kidney, replenish essence, nourish liver and improve eyesight.
4, black medlar boiled eggs: can nourish liver and kidney, benefit essence and blood, benefit qi and blood, suitable for neurasthenia, anemia, chronic hepatitis, vision loss and other symptoms (practice: medlar wash, control dry. Wash the eggs with shells, drain the water, put Lycium barbarum and eggs in a pot, add appropriate amount of water, and cook on the fire for 10 minute. Take out the eggs, peel off the eggshells, put them in a pot, and cook for a while before taking them.
Black Lycium barbarum is a good thing for health care, but if you buy fake black Lycium barbarum, it will not only be bad for your health, but also bring incalculable side effects, so you must learn to distinguish between good and bad black Lycium barbarum.
via
1, replaced by Nitraria tangutorum, this is because the color of Nitraria tangutorum is similar to that of Lycium barbarum, and you can't tell it without looking carefully. The price of Lycium barbarum is about 2000 yuan/500g, while the price of Nitraria tangutorum1000g can't sell 20 yuan money. It is pure fraud to sell Nitraria fruit as black wolfberry.
2. Spray water on the black wolfberry to increase its weight and humidity. This kind of black Lycium barbarum is unstable in nutrition and easy to mold and worm.
3. Replace it with blueberry fruit, remove the seeds from the smaller blueberry fruit, dry it and pretend to be black wolfberry. Blueberry fruit is a kind of berry without stone, while Lycium barbarum is multinucleated and easy to distinguish.
4. After dyeing with other similar fruits, pretend to be black wolfberry, which can be distinguished after brewing. Because black wolfberry contains anthocyanins, it is blue in acidic water and purple in alkaline water, and dyed black wolfberry can only brew one color.
Qinghai has the best quality, followed by Xinjiang and Gansu.
Identification method
1, soaking identification: Lycium barbarum L. is very thick in color and contains a lot of blue and white pigments, which will show different properties under different water quality. Soak acidic water (mineral water) into purple and alkaline water (mountain spring water, tap water, etc.) into purple. ) turns blue.
2. Appearance identification: Lycium barbarum fruit is dry and wrinkled, and the berries are oval, slightly flat after wet soaking. The surface is purple-black, with irregular wrinkles and a little luster. Remaining styles, stipe scars and persistent calyx of fruit. The texture is soft and moist. Seed 1 seed, oblong, reddish brown or brown, slightly pointed at the top, triangular, with shallow longitudinal grooves, extending to the middle, obtuse at the base, and with more than a dozen round dimples. Slight breath, sweet and sour taste. After the finished Lycium barbarum is dried in the sun, the handle can stand up, and the part after removing the fruit handle is a very round and white circle. When it is dry, it will become powder when squeezed by hand, which is some characteristics that other counterfeit fruits do not have.
3. Microscopic identification: Cross section of the pericarp: The epicarp of Lycium ruthenicum is a row of flat cells with thick wall, cuticle and microwave-like protrusions on the outer edge. The mesocarp consists of ten rows of parenchyma cells and contains calcium oxalate cubes. Double tough vascular bundle hash. Endocarp cells 1 row is small and elongated tangentially.
appraisal of quality
1. Origin: Generally speaking, Qinghai has the best quality, followed by Xinjiang and Gansu. But this is not absolute. In some places in Gansu, the quality of black wolfberry is also very good.
2. Particle size: At present, the particle size is mainly divided into the following grades: the diameter is above 17.5px, 0.5- 17.5px, 0.3- 12.5px and below 10px. The bigger the particles, the higher the price and the better the appearance. However, the medicinal value of Lycium barbarum with large particles is the same as that of Lycium barbarum with small particles.
3, cleanliness: black wolfberry is wild, there is no standardized production standards, picking and drying are very troublesome, resulting in a lot of impurities in black wolfberry. Cleanliness mainly depends on the ratio of bad fruit, yellow fruit, coffee fruit and dust/impurities. This item is the main difference between ordinary black wolfberry and selected black wolfberry, and the price difference is more than 2 times.
4. Anthocyanin content: Generally speaking, the black wolfberry in Qinghai has the highest anthocyanin content, the fastest outstanding speed and the strongest soaking color. However, excellent fast defoaming and excellent slow defoaming have their own advantages, and the final choice depends on consumers themselves.
