Pediatric spleen and stomach tonics should be taken for at least a month. Because of the relatively poor function of the spleen and stomach in children, it is easy to cause damage to the spleen and stomach, resulting in poor appetite, delayed growth, and lighter weight than children of the same age. Because damage to the spleen and stomach is a long-term chronic process, the course of medication to regulate the spleen and stomach is also long, and cannot be supplemented in a short period of time; otherwise, when the spleen and stomach are toned, not only will they not get good results, but they will cause symptoms such as abdominal distension and abdominal pain. Because the time taken to regulate the spleen and stomach is too short or the dosage applied is too large, children may suffer from deficiency. The amount of medicine should be relatively small and the course of treatment should be sufficient, mostly over one month, when regulating the spleen and stomach.
