Wang, female, 41 years old, was first diagnosed on September 13, 2009. She has been suffering from abdominal pain and diarrhea for more than 1 year, with 3-5 stools per day, thin stools, sometimes with mucus, accompanied by abdominal pain, which is aggravated by abdominal pain and diarrhea whenever there are mood swings, chest tightness and abdominal distension, belching and less food. On palpation of the abdomen, there is a cord-like mass on the umbilicus, with occasional low-grade fever. The tongue is red with petechiae, the fur is thin and white, and the pulse is thin and stringent. The diagnosis is Qi stagnation, blood stasis and liver and spleen dysregulation. Treatment is to dredge the liver and regulate qi, activate blood circulation and resolve blood stasis. Prescription: Chuan Hu Zi 9g, Yan Hu Suo 10g, Wu Yao 9g, Red Peony 9g, Dan Pi 9g, Fried White Peony 12g, Dan Shen 15g, San Ling 6g, Curcuma 6g, Licorice 5g. Decoction with water, taken on an empty stomach, 1 dose per day, after 10 doses, all symptoms were reduced and stools were formed. After taking 5 doses of the previous formula, the symptoms disappeared. The diarrhea in this case was caused by Qi stagnation, blood stasis and liver and spleen dysregulation. Therefore, we used neem, yanhuosuo and wu yao to dredge the liver and regulate qi; danshen, red peony, trigonella, curcuma longa and danpi to activate blood stasis; white peony and glycyrrhiza sour and sweet to dissolve yang, to ease urgency and harmonize the middle. The theory and method of prescriptions and medicines are effective. Most of the medical practitioners of all generations believe that diarrhea is caused by external evil, dampness and heat, spleen qi weakness, spleen and kidney yang deficiency, food stagnation in the intestines and stomach, and liver and spleen disharmony. The author believes that in addition to the above-mentioned causes, blood stasis can also cause diarrhea, and clinical activation of blood stasis is also an important rule in the treatment of diarrhea. If the liver likes to be organized, if the emotions are out of balance, the liver is depressed, the liver and spleen are not in harmony, the blood does not flow smoothly, the clear yang does not rise, the cloudy yin does not descend, the abdomen is painful and full, the transportation is out of order, the clear and cloudy mixes and goes down, and the large intestine is diarrhea. There are also cold and damp stagnation, Qi is not smooth, blood stasis curved intestine, clear and turbid is not separated, down the large intestine, and become diarrhea. Wang Qingren “medical forest correction” cloud: diarrhea for a long time, a hundred prescriptions do not work, is the total mention of blood stasis too much. Therefore, if the diarrhea is not cured for a long time, and the evidence is blood stasis, the treatment should be from stasis theory.
