The main way in which Hibiscus can enhance the body’s resistance is by increasing the beneficial bacteria in the body, that is, the probiotics in the gastrointestinal tract, which can mediate the digestive and absorption functions. The balance in the intestinal tract is usually caused by the balance of probiotics and harmful bacteria, if the probiotics are dominant, there will be a balance in the function of the gastrointestinal tract. If harmful bacteria such as E. coli and Enterococcus faecalis are dominant, poor digestion and absorption function, abdominal pain, bloating, diarrhea, nausea, vomiting, etc. will occur. Hapten can significantly regulate the flora in the gastrointestinal tract, enabling probiotics to predominate and enhance the body’s immunity by improving the function of the digestive system, thus promoting resistance.
