The main function is to stimulate the nerve plexus between the intestinal walls, increase the peristaltic speed of the intestine, and inhibit the absorption of water in the intestine, in order to relieve constipation. If you take the fruit guide tablets reasonably, the intestine will move quickly and the volume of stool will increase, and the stool stored in the intestine will be excreted quickly, so diarrhea will not occur. However, some people may take too large a dose of fruit-directed tablets, which may cause side effects. Overdose of fruit-directed tablets may lead to electrolyte disorders, spasm of the intestinal wall, and even secretion of intestinal fluid due to strong irritation of the intestine, resulting in diarrhea. Long-term use of the tablets can also lead to a reduced stress response in the intestine, and the absorption of nutrients can be affected, leading to diarrhea.
