Whether it is Qinghai or Xinjiang, the first thing to look at is quality.
Many people think that Qinghai is the birthplace of Lycium barbarum. This is because it was originally found in Qinghai and Xinjiang, but it was discovered slowly. With the rising price of Lycium barbarum, large-scale cultivation of Lycium barbarum has become the mainstream. At this time, we began to fight for quality, and it was meaningless to fight for the place of origin.
The best research on the origin of Lycium barbarum shows that the most suitable growth environment of Lycium barbarum is: annual average temperature-1-5 degrees, annual precipitation of 40-400 mm, less precipitation, greater temperature difference and higher anthocyanin content.
Where is the best black wolfberry?
Lycium barbarum is a unique desert medicinal plant species in western China, which is scattered in Helan Mountain in Ningxia, eastern Qinghai, northern Xinjiang, western Inner Mongolia, northwestern Shaanxi, Gansu and Tibet. Among the few Lycium barbarum producing areas, Chaidamu, Qinghai is recognized as the real wild Lycium barbarum producing area .. so the wild Lycium barbarum produced here contains the highest anthocyanins and nutrients.
1. Origin of Lycium barbarum: Different origins vary in size and quality.
The black wolfberry in Xinjiang is the largest, with no fruit stalks, gray and beautiful. However, you will know that the anthocyanin content is still the highest in Qinghai. Therefore, in the black wolfberry, Qinghai is recognized as the best producing area.
2, head size: Qinghai wild black wolfberry, because of the harsh growth environment, the fruit will be relatively smaller than Xinjiang.
The main health care value of Lycium barbarum lies in its rich anthocyanin, which is a natural antioxidant that can help the human body eliminate free radicals, resist wrinkles and aging, and prevent cancer. There are still some health care values to be explored.
1, nourishing the liver and improving eyesight.
Medical clinical reports show that anthocyanins in Lycium barbarum can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and have obvious visual protection effects, and have good health care effects on adolescent pseudomyopia, dizziness, fundus hemorrhage, diabetic retinopathy, cataract, asthenopia, dry eye and so on. Anthocyanins can improve their eyesight in dim light, which is helpful for drivers at night and people who stare at the screen for a long time.
2, kidney and essence, cancer prevention
Anthocyanins in Lycium barbarum 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.
3. Promote fluid production to quench thirst and improve circulation.
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 pain, edema, night cramps and other symptoms, so European doctors usually recommend patients with varicose veins to eat blueberry, a food rich in anthocyanins.
4. Enrich blood, soothe the nerves and improve sleep
It can prevent the early generation of skin wrinkles and is the most effective antioxidant in nature at present. 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 it is protected by anthocyanins, about a part of skin cells can survive.
