秦子说：痢疾的症状，是大便排出脓血，颜色或红、或白、或黄，或三种颜色混杂而下，伴有里急后重（腹痛窘迫，时时欲便，肛门重坠，便出不爽），想排便却排不出，刚排完又想再去厕所，这种症状逼迫恼人。如果只是腹泻水谷，没有脓血停滞，这名叫水泻，而不是痢疾。痢疾必须区分外感和内伤，天行时气自感而得的病证。大概夏秋季节外感时行邪气的痢疾，是手足阳明经和肠胃二经受病；其他三个季节因内伤导致的、只有一个人患病的痢疾，是三阴经中的脾肾受病。以前的书籍，混淆地立论，未曾分别清楚。所以我详细辨别外感的四条，内伤的……
【寒湿痢的症状】初起时恶寒发热，身体疼痛，头痛，呕吐，不想吃东西，不口渴，痢下脓血，或者下黑水，腹部胀满闷痛。感受于阳明经，出现寒热往来；感受于少阳经，三阳经的病邪不解，传入体内，在伤寒中叫传经之邪，在痢疾中叫风邪内缩，是从阳经传入体内的症状。
【寒湿痢的病因】寒水和湿土的政令流行，气候卑湿，寒湿时行邪气盛行，人体内部正气不足，乘虚感入，郁遏营卫之气，卫气郁滞，营血凝涩，内传肠胃，导致水谷不能消化，气血与糟粕互相蒸酿，于是痢下赤白的症状就产生了。
【寒湿痢的脉象】左脉浮紧，是太阳寒湿；右脉浮大，是阳明寒湿。寒湿潜伏在内，脉象就会沉紧。如果……
【寒湿痢的治疗】身体疼痛发热，脉浮紧的，适宜用败毒散，辛温发散表邪。呕吐饱闷，脉长的，用干葛平胃散调和胃气，宽胸理气。小便不利的，用散表利湿的五苓散。不像燥热痢，禁止利小便。又不同于燥热痢，妄用大黄。也不可同湿热痢一样，误用黄连。如果遇到大旱寒冷天气，那么寒湿就不会消散，反而抑遏内缩，传入体内，仍然要先治疗外邪，使它们从体表排出，所以寒湿痢一定要先用解表散邪的方法。

Qin Zi said: The symptoms of dysentery include the passage of pus and blood in the stool, which may be red, white, yellow, or a mixture of all three colors. It is accompanied by tenesmus (a feeling of incomplete defecation with urgency and pain), where one feels the urge to defecate but cannot, or feels the need to return to the toilet immediately after defecating. This condition is oppressive and distressing. If there is only diarrhea of water and undigested food without pus or blood, it is called watery diarrhea, not dysentery. Dysentery must be distinguished into external contraction and internal injury. Epidemic dysentery contracted from heavenly qi is primarily related to the Foot-Yangming and Hand-Yangming meridians and the intestines and stomach. Dysentery occurring in other seasons due to internal injury, affecting only one individual, is primarily related to the Three Yin meridians, specifically the Spleen and Kidney. Previous texts have confused these concepts without clear distinction. Therefore, I have detailed four types of external contraction dysentery, and internal injury...
[Symptoms of Cold-Damp Dysentery] At the onset, there is aversion to cold and fever, body ache, headache, vomiting, anorexia, absence of thirst, passage of pus and blood in the stool, or passage of black fluid, abdominal distension and fullness. Contraction in the Yangming channel presents with alternating chills and fever; contraction in the Shaoyang channel involves the unresolved pathogenic factors of the Three Yang channels transmitting inward. In Shanghan (Cold Damage), this is called transmitted pathogenic factors; in dysentery, it is called wind pathogen retreating inward, representing symptoms transmitted from the Yang channels into the interior.
[Etiology of Cold-Damp Dysentery] When the policies of Cold Water and Damp Earth prevail, leading to damp and low-lying climatic conditions, epidemic cold-damp pathogens are prevalent. If the internal Qi is insufficient, pathogens enter through deficiency, stagnating and obstructing Ying and Wei Qi. With Wei Qi stagnated and Ying Blood congealed, the pathogen transmits inward to the intestines and stomach, causing failure of digestion of water and grain. The Qi and Blood ferment and brew with waste matter, resulting in the symptom of passing red and white discharge in dysentery.
[Pulse Signs of Cold-Damp Dysentery] A floating and tight pulse on the left indicates Taiyang Cold-Damp; a floating and large pulse on the right indicates Yangming Cold-Damp. If Cold-Damp lies latent within, the pulse becomes deep and tight. If...
[Treatment of Cold-Damp Dysentery] For body ache, fever, and a floating-tight pulse, Baidu San (Decoction for Rescuing from Ten Thousand Perils) should be used to release the exterior with acrid-warm herbs. For vomiting, fullness, and a long pulse, Gan Ge Pingwei San (Pueraria and Pingwei Powder) should be used to harmonize the Stomach and broaden the chest. For difficulty in urination, Wuling San (Five-Ingredient Powder with Poria) should be used to release the exterior and promote diuresis to resolve dampness. Unlike dry-heat dysentery, diuresis is contraindicated. Unlike dry-heat dysentery, Da Huang (Rhubarb Root and Rhizome) should not be used recklessly. Nor should Chuan Lian (Fruit of Sichuan Chinaberry) be mistakenly used as in damp-heat dysentery. If severe drought and cold occur, cold-damp will not dissipate but rather retreat inward; thus, the exterior pathogen must first be treated to allow it to exit via the surface. Therefore, releasing the exterior is essential in treating cold-damp dysentery.

Add Fang Feng (Saposhnikoviae Radix) if there is no sweat. Remove Ren Shen and add Zhi Ke (Aurantii Fructus) if there is chest fullness. If there is abdominal fullness, anorexia, vomiting, and nausea, indicating concurrent Stomach disease of the Yangming channel, add Pingwei San below. My family secret name is Baidu Pingwei San.
