Gastric mucous membrane injury is commonly seen in western medicine in gastritis, gastric ulcer and other diseases, but in Chinese medicine, it belongs to the category of “stomach pain”, and its treatment should be based on the evidence of the use of medication, and commonly used medicines include Lost Smile San and Lizhong Pill. Lost Smile San contains Pu Huang, Wu Ling Yi and other Chinese medicinal ingredients, which have the efficacy of activating blood circulation to dispel blood stasis, and dispersing knots to relieve pain. It can be used to treat gastric pain caused by stagnation of blood stasis, which is characterized by acute pain in the lesser abdomen (abdomen) that refuses to be pressed. This formula is contraindicated in pregnant women, and should not be used in women with weak spleen and stomach and during menstruation. Lizhong Pill contains Radix Codonopsis Pilosulae, Radix Gingerae, Rhizoma Atractylodis Macrocephalae, Radix et Rhizoma Glycyrrhizae and other Chinese medicinal ingredients, which have the efficacy of warming the middle part of the body and dispersing coldness (dispersing coldness by warming the spleen and the stomach), strengthening the stomach and can be used for treating gastric pain due to deficiency of coldness in the spleen and stomach, which can be seen as fullness of the chest (chest distension and discomfort), abdominal pain, vomiting and diarrhea and dyspepsia. It should not be taken by those who suffer from heat, distension and pain in the abdomen during diarrhea. All of the above proprietary Chinese medicines can be used to treat stomach pain, but the specific selection should also be under the guidance of the physician’s diagnosis, not blindly self-medication.
