Long-term chronic diarrhea is generally very difficult to treat. The common clinical type in TCM is mainly spleen deficiency. The main symptom is chronic loose stools, always unformed, and diarrhea when you eat too cold, sometimes many times a day. Sometimes it is not digested well. This is because the spleen is weak and cannot transport water and grain. The prescription is as follows: 10g of Radix Codonopsis, 10g of Poria, 6g of Huang Lian, 6g of Ginger, 6g of Mullein, 3g of Sandy Nut (later), 10g of Lentil, 15g of Yam, 10g of Jiao San Xian, 10g of Fried Atractylodes, 5 decoctions (the decoction should be small, too thin to affect the effect). This is an extremely calm remedy with few side effects to worry about. It may not look amazing, but people with chronic diarrhea or chronic loose stools should definitely pay attention to this formula. It has a very unusual origin. Clinical results can always be seen in 3 to 5 doses.
