痢疾暑湿生冷成，伤气为白伤血红，后重里急腹窘痛，寒热时痢噤口名。
【注】痢之为证，多因外受暑湿，内伤生冷而成。伤于气者色多白，以肺与大肠为表
里也。伤于血者色多赤，以心与小肠为表里也。里急者，腹窘痛也；后重者，频下坠也。
又有寒痢、热痢、时痢、噤口痢之别，医者须详察之。
寒伤久痢脏虚寒，肠鸣切痛实难堪，面唇青白喜饮热，理中养脏效通仙。
【注】寒痢者，寒冷伤胃，久痢不已，或脏气本虚，复为风冷所乘，伤于肠胃。故痢
时肠鸣切痛，面唇青白，口虽渴喜饮热。此里寒虚之证也。初宜理中汤，久则真人养脏
汤治之。寒得温散而证愈矣。

Dysentery is often caused by the combined action of summer-heat and dampness pathogens along with raw and cold food. Injury to the Qi level results in white-colored stool, while injury to the Blood level results in red-colored stool. Symptoms characterized by tenesmus (urgent need to defecate) and abdominal distress are termed "houzhong liji" (posterior heaviness and internal urgency). If accompanied by alternating chills and fever or an inability to eat, it is respectively referred to as epidemic dysentery or jin Kou dysentery (dysentery with inability to swallow).
[Note] The syndrome of dysentery is mostly caused by external contraction of summer-heat and dampness, and internal damage from raw and cold foods. When the pathogen affects the Qi level, the stool color tends to be white, because the Lung and Large Intestine are exterior-interiorly related. When the pathogen affects the Blood level, the stool color tends to be red, because the Heart and Small Intestine are exterior-interiorly related. "Li ji" refers to abdominal cramping pain; "Hou zhong" refers to frequent urge to defecate with a sensation of bearing down. Furthermore, there are distinctions among cold dysentery, heat dysentery, epidemic dysentery, and jin Kou dysentery; physicians must examine them in detail.
Cold-induced chronic dysentery belongs to the deficiency-cold syndrome of the zang-fu organs, manifesting as borborygmus (intestinal rumbling), severe abdominal pain that is hard to endure, cyanotic and pale face and lips, and a preference for drinking hot water. Lizhong Tang (Regulate the Middle Decoction) and Zhenren Yangzang Tang (Genuine Human Nourish Viscera Decoction) are highly effective, akin to celestial elixirs.
[Note] Cold dysentery occurs when cold damages the Stomach qi, leading to chronic dysentery that does not heal; or when the organ qi is originally deficient, compounded by invasion of wind-cold, damaging the intestines and stomach. Therefore, during dysentery episodes, there is prominent borborygmus and severe cutting abdominal pain, the face and lips appear cyanotic and pale, and although thirsty, the patient prefers hot drinks. This is a syndrome of interior cold and deficiency. Initially, Lizhong Tang is suitable; for prolonged cases, Zhenren Yangzang Tang is used to treat it. Once the cold is dispersed by warmth, the syndrome resolves.

Initial dysentery presenting as excess-heat involves abdominal distress and pain, profuse diarrhea, short and red urine, a red tongue and scorched lips, and a preference for drinking cold water. Shaoyao Baitou Xianglian Ling formula may be used.
[Note] Heat dysentery is caused by the coagulation of damp-heat in the intestines and stomach, resulting in abdominal distress and pain, frequent diarrhea, short and red urine, a red tongue with scorched lips, and a preference for drinking cold water. This is a syndrome of interior heat. In severe cases, Danggui Shaoyao Tang (Angelica and Peony Decoction) is the primary treatment; in mild cases, Baitouweng Tang (Pulsatillae Decoction) is used, or Xianglian Wan (Mu Xiang and Coptis Pill).
