【脉象】
脉象滑利，按之空虚无力者，必定是痢疾。寸口脉浮数，尺部脉涩，必定排出青色脓血。脉象沉弦，必定伴有排便沉重感（后重）。脉象数，如果伴有轻微发热、出汗，会自行痊愈。脉象微弱而数，痢疾会自行停止。脉象沉小且持续存在，容易治疗；脉象数大且身体发热，难以治疗。
【症状】
痢疾的症状，有的排脓，有的便血，有的脓血混杂，有的像肠垢，有的没有未消化的食物残渣混合。虽然疼痛程度有轻痛和大痛的区别，但都伴有里急后重（腹部拘急紧迫，肛门坠胀），令人烦恼难受，这叫做痢疾。痢疾属于湿热和食积三种病因。分别根据青、黄、赤、白、黑五色来归属五脏：白色是湿热损伤气分，红色是湿热损伤血分，红白相间是气血都受伤，黄色是食积，或者说是青绿杂色，这是风与火邪所致。下痢如豆汁样，是赤白相混，属于湿毒。钱乙说：红、黄、黑都属于热证，青白且完谷不化属于寒证。考察其根本原因，都是由肠胃受纳的饮食积滞，未能完全运化，留滞在体内，湿气蒸腾，热气秽浊，郁结日益加深，潜伏而不发作，时常遇到炎热暑天，相火当令，加上调养失宜，又感受酷热之毒，到了秋天阳气开始收敛，火气下降，蒸热蓄积，于是滞下的病症就发作了。因为是由于积滞的“滞”而行，所以名叫滞下，也就是痢疾。湿热秽浊积滞干扰血分则便赤，干扰气分则便白，赤白混杂下行，说明气血都受了邪气。时间久了不愈，气弱不能运化，脾虚不能磨化，陈旧的积滞既已滑利，下行凝结就像鱼脑一样。严重时脾胃空虚，固摄失职，浊液迸流，颜色不单一，错杂混下，形状像豆汁。如果脾胃下陷，虚坐努责（想排便但无物可出，用力挣扎），颜色像白脓。如果热邪伤血深重，湿毒积秽粘结成紫色，就会变成紫黑色。秽浊积滞想要排出，但气机阻滞不能随之排出，所以下迫窘迫疼痛，后重里急，频繁想大便却解不出来。这都是大肠经有所阻塞阻碍，气液不通的缘故。应当详细审察。
【治法】
刘河间说滞下症，属于湿热郁遏肠道所致。又说“无积不利”，初起一两天，元气尚未虚弱者，应用攻下法。如枳壳、大黄之类。这是“通因通用”的方法。又说“行血则便脓自愈”，用当归、白芍药、桃仁、红花之类。“调气则后重自除”，用木香、槟榔之类。切忌使用止涩药物。又说后重适宜用攻下法，木香槟榔丸主治。腹痛适宜调和，用白术、白芍药、甘草、陈皮、当归之类。身重适宜温补，用干姜、附子之类。脓血稠粘，用重剂攻逐。身冷自汗，用重剂温补。风邪内缩，适宜发汗，用防风、羌活之类。大便溏薄为泄利，用温法，用附子理中汤之类。病在表用汗法，病在里用下法，病在上用涌吐法（即吐法），病在下用攻下竭除法（即下法）。身体表面发热，用内疏法，用柴胡、葛根之类。小便涩滞，用分利法，用五苓散之类。火热证用寒凉清泻法，用黄芩、黄连之类。气滞用调理法，用木香、槟榔、枳壳之类。积滞用去除法，用枳实、厚朴、大黄之类。气虚而下陷的用升举法，用人参、黄芪、白术、甘草、升麻之类。血虚的用补益法，用人参、当归、芍药之类。呕吐的用和胃法，用生姜、半夏、陈皮之类。噤口痢（不能进食），是胃热，用人参、黄连补益并清泻。各根据其类别施治。变证多种多样，难以一一列举，姑且摘录要点，以等待懂医的人参考。

[Pulse]
A slippery pulse that feels empty and weak upon deep pressure indicates dysentery. A floating and rapid pulse at the cun position with a choppy pulse at the chi position indicates the passage of greenish pus and blood. A deep and wiry pulse indicates tenesmus (a feeling of incomplete defecation). A rapid pulse accompanied by slight fever and sweating will resolve spontaneously. A faint, weak, and rapid pulse indicates the dysentery will stop on its own. A deep and small pulse that persists is easy to treat; a rapid and large pulse accompanied by high body heat is difficult to treat.
[Symptoms]
Dysentery may present with pus, blood, a mixture of pus and blood, intestinal mucus, or without undigested food residue. Although there are differences in pain intensity ranging from mild to severe, all cases involve tenesmus and abdominal urgency, causing distress. This condition is termed "dysentery" and belongs to damp-heat and food stagnation. The colors green, yellow, red, white, and black correspond to the five zang organs: white indicates damp-heat injuring the qi level; red indicates damp-heat injuring the blood level; a mixture of red and white indicates injury to both qi and blood; yellow indicates food stagnation; or greenish/mixed colors indicate wind and fire pathogens. Stools resembling bean juice, mixed with red and white, indicate damp-toxin. Qian Yi stated that red, yellow, and black indicate heat, while green/white with undigested food indicates cold. Examining the root cause, all stem from dietary accumulation in the intestines and stomach that fails to transform completely, remaining stagnant internally. Dampness steams and heat turbidity accumulates, becoming deeply constrained. It lies dormant until triggered by summer heat when ministerial fire dominates, combined with improper lifestyle management and exposure to intense heat toxins. In autumn, as yang energy begins to收 (gather) and fire energy descends, the accumulated heat and stagnation trigger the onset of "stagnant discharge" (Zhi Xia), hence the name for dysentery. When damp-heat and turbid stagnation interfere with the blood level, stools are red; when interfering with the qi level, stools are white; a mixture indicates both qi and blood are affected. If chronic, qi deficiency leads to poor transport, spleen deficiency fails to grind food, and old stagnation becomes slippery yet coagulates downward like fish brains. In severe cases, spleen and stomach emptiness leads to loss of retention control, causing turbid fluids to flow freely, resulting in mixed colors resembling bean juice. Sinking of spleen and stomach qi causes false straining (feeling the need to defecate but producing nothing) with white pus-like discharge. Deep blood injury by heat and accumulation of damp-toxin can result in purple-black stools. Turbid stagnation desires to exit but is blocked by qi stagnation, causing urgent lower abdominal pain and tenesmus, frequent urges to defecate without success. This is due to obstruction in the Large Intestine meridian blocking qi and fluid flow. Careful examination is required.
[Treatment Principles]
Liu Wansu stated that stagnant discharge belongs to damp-heat constraining the intestines. He also said "no accumulation, no dysentery." In the initial one or two days, if vital qi is not yet deficient, purgative methods should be used, such as Zhiqiao (Bitter Orange) and Dahuang (Rhubarb). This is the method of "treating obstruction with unblocking agents" (Tong Yin Tong Yong). He further stated that promoting blood circulation heals pus in stools, using Danggui (Angelica Sinensis), Baishao (White Peony Root), Taoren (Peach Kernel), and Honghua (Safflower). Regulating qi eliminates tenesmus, using Muxiang (Costus Root) and Binglang (Areca Seed). Astringents must be strictly avoided. For tenesmus, purgatives are indicated, such as Muxing Binglang Wan (Costus and Areca Pill). For abdominal pain, harmonization is needed, using Baizhu (Atractylodes Macrocephala), Baishao, Gancao (Licorice), Chenpi (Tangerine Peel), and Danggui. For heavy sensation, warming is indicated, using Jiang (Ginger) and Fu (Aconite). For thick, sticky pus and blood, strong purgatives are used. For cold limbs and spontaneous sweating, strong warming agents are used. For internal contraction of wind pathogens, diaphoresis is indicated, using Fangfeng (Saposhnikovia) and Qianghuo (Notopterygium). For loose stools (diarrhea), warming is used, such as Fuzi Lizhong Tang (Aconite and Ginger Decoction). Exterior conditions require diaphoresis; interior conditions require purgation; upper conditions require emesis; lower conditions require purgation/expulsion. For exterior heat, internal dispersal is used, such as Chaihu (Bupleurum) and Gegen (Kudzu Root). For astringent urination, separation and drainage are used, such as Wuling San (Five-Ingredient Powder with Poria). For fire-heat, cooling and clearing are used, such as Huangqin (Scutellaria) and Huanglian (Coptis). For qi stagnation, regulation is used, such as Muxiang, Binglang, and Zhiqiao. For stagnation, removal is used, such as Zhishi (Immature Bitter Orange), Houpo (Magnolia Bark), and Dahuang. For qi deficiency with sinking, lifting is used, such as Renshen (Ginseng), Huangqi (Astragalus), Baizhu, Gancao, and Shengma (Cimicifuga). For blood deficiency, tonification is used, such as Renshen, Danggui, and Shaoyao (Peony). For vomiting, harmonizing is used, such as Shengjiang (Fresh Ginger), Banxia (Pinellia), and Chenpi. For Jin Kou Li (anorexic dysentery), which is due to stomach heat, Renshen and Huanglian are used to tonify and clear. Treatments follow their respective categories. Variations are numerous and cannot be fully listed; only key points are excerpted here for experts.
