Long term use of Kaisailu is harmful to the body. Kaiselu is a kind of toilet used locally in the anus. It can be used occasionally to moisten the intestines and relieve constipation. However, if it is used frequently, it will cause the normal physiological defecation reflex of the rectum and anal canal to be weakened, and cannot discharge the stool normally. Instead, it needs to rely on the use of this drug to defecate, which will cause more serious diseases over a long period of time. Therefore, if you can defecate by yourself, it is generally not recommended to use this product. Even if you have constipation, you should also try to focus on diet and lifestyle conditioning. For example, if you eat more food containing fiber, you can use this medicine only when it can't be improved.
