According to the meridian Liu Zhu's law based on the theory of "correspondence between man and nature", it is more appropriate to eat from 5 pm to 7 pm, but it is also good to eat at other time periods. Although Lycium barbarum is a good thing, it is no good to eat too much, just like other nutritional supplements. Generally, a healthy adult eats 10g (about fifty or sixty capsules) a day, which is enough to meet the nutritional needs of the body. If you eat too much, you are likely to get angry.
