In today’s society, the number of only children has increased, and several elderly people at home surround a child, fearing that the child is malnourished, often consuming a high protein diet, but parents still feel that the child does not eat well, so the clinical clinic often see children who come to the clinic because of constipation. These children, generally well-developed, often have stools that are difficult to solve, time-consuming and laborious, and occasionally lead to anal fissures with fresh blood on the surface of the stool, because the child is a child’s Yin and Yang body, conventional rhubarb, senna and other bitter cold laxatives parents dare not use, when helpless to use open plug, or seek treatment from Chinese medicine. The author believes that most of these patients are liver and spleen deficient, impatient, and even like to hit and bite people, move and sweat a lot, and often have hot palms, and at first they can eat, but after constipation, their appetite decreases, and after the decrease in appetite, parents are afraid of nutritional deficiencies, and increase the high protein diet, so the vicious cycle, the disease is difficult to solve, and the diet multiplies, which hurts the spleen and stomach, and over time leads to weakness of the spleen and stomach, and even to chancre. The author often uses Xiao Chai Hu Tang with added flavor to treat this condition and often obtains good results. The treatment of constipation with Xiao Chai Hu Tang is inspired by the provisions of Xiao Chai Hu Tang in the Jin Kui Yao. In the Jin Kui Yao – Women’s Postpartum Diseases Pulse Evidence Treatment XXI, it is recorded that “the maternal depression, the pulse is weak, can not eat, the stool is firm, but the head sweats, so it is because the blood is deficient and syncope, syncope and will be adventurous. If the patient wants to be relieved, he must sweat a lot. The head sweats because the blood is deficient and the lower syncope, the lonely yang up out, so the head sweats. So the maternal happy sweating, the death of Yin blood deficiency, Yang alone, so when sweating, Yin and Yang is restored. The stool is firm, vomiting can not eat, Xiao Chai Hu Tang is the main.” In the original text, this formula treats constipation in women with blood loss and sweating after childbirth and loss of fluid, while children with constipation often sweat more and move more due to excessive intake of high protein, resulting in excess calories, and sweating more leads to death of fluid and dryness of the stomach, so the stool is difficult to resolve, and can also be treated with Xiao Chai Hu Tang.
