This formula is indicated for damp-heat dysentery. The symptoms are dysentery with stool containing pus and blood, abdominal pain, abdominal urgency with rectal heaviness, burning sensation in the anus, scant dark urine, a greasy yellow tongue coating, and a wiry rapid pulse. |
【Pathogenesis】 |
This is a pattern of dysentery caused by an accumulation and obstruction of damp-heat in the large intestine, and qi-blood disharmony. Damp-heat steams and burns the large intestine, the large intestine fails to conduct and transmit, the qi and blood accumulate and obstruct, and the blood vessels in the large intestine become damaged, which lead to dysentery with stool containing pus and blood. Since the large intestine is obstructed, the bowel qi fails to descend and there is abdominal pain and abdominal urgency with rectal heaviness. The burning sensation in the anus, scanty dark urine, greasy yellow tongue coating, and wiry, rapid pulse are signs of the internal accumulation of damp-heat. The characteristic feature of this pattern’s pathogenesis is the accumulation and obstruction of damp-heat, and qi-blood disharmony in the large intestine. The three major symptoms are abdominal pain, abdominal urgency with rectal heaviness, and dysentery with stool containing pus and blood. Given the pathogenesis and major symptoms of the pattern, the therapeutic method, as recorded in《Collection of Writings on the Mechanism of Disease, Suitability of Qi, and the Safeguarding of Life as Discussed in the ‘Basic Questions’》Su Wen Bing Ji Qi Yi Bao Ming Ji《素問病機氣宜保命集》, is to “invigorate the blood to relieve stool with pus and blood, and moving qi to relieve abdominal urgency with rectal heaviness”. Therefore, the therapeutic method is to invigorate the blood, move qi, clear heat, and dry dampness as the principle focus, and guide out food stagnation as the supplementary focus. |
