痢疾
Alias里急后重
Traditional Chinese Medicine Definition
In traditional Chinese medicine, dysentery is referred to as "痢" or "滞下," which is characterized by the invasion of pathogenic factors such as dampness-heat, epidemic toxicity, and cold-dampness into the spleen and stomach, leading to dysfunction of the intestines and colon. This manifests as symptoms such as abdominal pain, urgent need to defecate, and diarrhea with red and white pus and blood. According to the records in "Internal Medicine of Traditional Chinese Medicine," dysentery falls under the category of spleen and stomach diseases, with its pathogenesis often related to pathogenic factors such as dampness-heat, epidemic toxicity, and cold-dampness, presenting with symptoms like abdominal pain, urgent need to defecate, and diarrhea with red and white pus and blood.
Dysentery is a common disease in the field of traditional Chinese medicine, categorized under spleen and stomach diseases. Its core pathogenesis involves dampness-heat in the spleen and stomach, internal accumulation of epidemic toxicity, or obstruction by cold-dampness. Common triggers include unclean diet, external pathogenic invasion, and emotional disharmony. In the process of differentiation, it is crucial to differentiate between cold and heat, as well as deficiency and excess. For instance, dampness-heat dysentery is characterized by abdominal pain, urgent need to defecate, diarrhea with red and white pus and blood, and burning sensation at the anus. Epidemic toxicity dysentery presents with an acute onset, fresh purple pus and blood in the stool, and severe abdominal pain. Cold-dampness dysentery is characterized by diarrhea with red and white sticky jelly, more white than red, and abdominal pain with an urgent need to defecate. The overall approach to treatment suggests clearing heat and dampness, regulating Qi and blood circulation, clearing heat and detoxifying, cooling blood and stopping diarrhea, warming the middle-jiao and drying dampness, regulating Qi and blood, to restore the function of the spleen and stomach, harmonize Qi and blood, and achieve therapeutic goals.
