First of all, strictly speaking, Lycium barbarum is not commonly used in our life, but the dried and mature fruit of Lycium barbarum, also known as Lycium barbarum, thorn fruit, Ming Mu Zi and so on. Lycium barbarum is mainly produced in Ningxia, Qinghai, Shandong, Henan and other places in China. Eating Lycium barbarum has many benefits to the human body, and the most obvious function is to improve eyesight and beauty. Lycium barbarum can nourish kidney essence Chinese medicine believes that kidney belongs to water and liver belongs to wood. Aquatic wood, when the kidney essence is sufficient, the liver benefits first, and the liver begins to understand the eyes, so eating more Lycium barbarum can improve eyesight. Moreover, Lycium barbarum can improve the ability of skin to absorb nutrients, and the content of β -carotene in Lycium barbarum is higher than that in carrots. Natural β -carotene can resist aging, cancer and prevent the damage of sunlight to the skin, so Lycium barbarum has a certain skin care effect.
If you don't eat Lycium barbarum and only drink Lycium barbarum water, then only a small amount of bioactive substances such as β -carotene and lutein may precipitate out, and most of them are still in the pulp. Many people think that soaking Lycium barbarum in hot water can "activate" nutrition and soak it out. In fact, the advantage of soaking Lycium barbarum in hot water is that it can soak Lycium barbarum in a short time and play a certain bactericidal role. But the disadvantage is also obvious, which is easy to destroy the vitamins in Lycium barbarum, because there are many vitamins that are not resistant to high temperature. Therefore, soaking Lycium barbarum in hot water can not play a good role in supplementing nutrition.
It should be noted that although Lycium barbarum is good, it is not suitable for everyone. Because Lycium barbarum itself has the function of warming the body, people with weak constitution and poor resistance can eat more in moderation, and people with colds, fever, inflammation and diarrhea should not eat it. For healthy people, Lycium barbarum should not be eaten more.
