Lycium barbarum is a tonic, which is hot, or causes excessive internal heat; So you will be constipated. I suggest you eat some honey and don't buy it in the supermarket. Most of the concentrated honey in the supermarket has little activity and no effect after high temperature concentration, which is almost the same as sugar water. I often drink Lycium barbarum in water myself, and add some honey at the same time. The honey I use is Buzz Valley honey, a natural mature active honey; Very good! There is no constipation, of course, eating honey also has many benefits! Benefit without harm.
