【脉象】
脉象滑利，重按却空虚无力甚至摸不到的，必定出现下利（腹泻）；如果寸口脉反而浮数，尺中脉涩，必定排出清稀的脓血。脉象沉弦的，会有里急后重感；脉象大小不一的，说明病势未止。脉数，如果伴有轻微发热、自然出汗的，会自愈；假如脉象再次变得紧实，必定病邪未解。脉微，如果兼见数脉且能自行停止下利的，虽然发热也不会死亡；脉象反见弦象，伴有发热、身体出汗的，也会自愈。脉搏暂时消失、手足厥冷的，施灸后手足转温的能生还；如果脉搏不恢复，反而出现轻微喘息的，则死亡。脉迟而滑的，属于实证。下利未止，应当用攻下法；脉数而滑的，是有宿食停滞，应当用攻下法。肠道排出白色粘液，脉象沉的预后良好，脉象浮的预后不良。肠道排出脓血，脉象悬绝（极度异常）的预后不良，脉象滑大的预后良好。脉象又沉小且连绵不断的预后良好，脉数大且有热象的预后不良。肠道痉挛抽筋，脉象极数的预后不良。凡是各种痢疾泄泻注下，脉象沉小的预后良好，脉象浮大的预后不良。身体发热的预后不良。如果有胡言乱语，或者腹部坚硬疼痛，脉象沉紧的，可以用攻下法；脉象迟缓的，可以用温法。下痢不想吃东西，是有宿食；肠满痛，是寒食积滞；肠部坚硬、心下部也坚硬的，是实证，都可以用攻下法。下痢脉迟，腹痛肠鸣，心急、肛门疼痛的，都可以用温法。伤寒引起的下痢，三部脉都摸不到，但尺中脉偶尔微弱显现，脉象举指时头部明显跳动的，这是肾气尚存的表现。形体衰败、脉搏不至的预后不良。
【病因】
从风湿热的角度论述，则是火气旺盛而肺气受损，导致肝木独旺而脾土受损。轻则表现为完谷不化的泄泻，身体发热，脉象洪大，食物不能消化；重则表现为下利脓血。医经说：春天感受风邪，夏天必定发生完谷不化的泄泻。又说：所有的下利，都属于湿邪所致。又说：下利稠粘，都属于火邪所致。又说：下利脓血，都属于滞下（痢疾）。
【证候】
上述证候，都是热证、实证。忌讳使用龙骨、赤石脂、罂粟壳等收敛固涩的药物。虚证导致的泄利，水谷有的消化、有的不消化，并没有努责（用力排便）的感觉，只觉得困倦乏力，脉象弦涩的就是这种情况。适宜用温补法治疗。
【治法】
治疗方法，病情重的用大黄汤为主方，病情轻的用黄芩芍药汤为主方。有里急后重感的应当用攻下法，这是因为有形之邪结聚坠胀。里有热邪、脉象洪大严重的，应当用攻下法；如果脉象洪大特别严重，就不宜用攻下法。如果是大肠经气机不畅，加木通、槟榔、木香。肠痛则适宜调和，胃气不和，当用茯苓、当归、芍药来调和。身体沉重则祛除湿邪，脉弦则祛除风邪。风气因动而内陷，用大柴胡汤为主方。血脓稠粘，用重剂药物清除，是因为热邪很盛。身体寒冷、自汗出，用温热性质的药物温补。有突然大量下利无声、身体寒冷、自汗出、小便清长通畅、大便失禁、气息短促难续、脉象沉微、喘息呕吐的情况，虽然有里急后重感，这是寒邪在内导致气机散乱。可以用温热药物使病情安定，如浆水散就是这类方子，归属于少阴病。风邪在内收缩，应当用发汗法。有厥阴病下利不止，脉象沉迟，手足厥冷，鼻涕唾液中带脓血，这难以治疗，适宜用麻黄汤、小续命汤来平调。医法说：如果有表邪内陷，应当疏散表邪从而使病情安定。李东垣的升举阳气方法也是如此。大便溏薄为下利，适宜用温法。如果说下利中有干硬粪便，属于太阴病。有里实的应当攻下。或者有里急后重，或者有食积与气机下坠，应当攻下。病位在上方的应当涌吐。或者是痰气在上方，涌吐可使病情安定；病位在下方，应当用重剂清除。大法则是：去者送之（通因通用），盛者和之（调和），过者止之（收敛固涩）。假如恶寒发热，腹部不痛，以茯苓为主药；疼痛严重，加当归，加倍芍药。如果见血，加黄连；或者发热恶寒，不用黄芩不能止住，这是上部出血。如果恶寒、脉沉、腰痛，或者白痢下利疼痛，或者便血，不用黄连不能止住，这是中部出血。或者恶寒、脉沉，先便血后大便，不用地榆不能止住，这是下部出血。
痢疾下利，有风、湿、热、寒、虚的区别，滞下、噤口痢、疳痢、瘵痢、湿蚀疮，病症相同但病因不同。血痢，有瘀血、血枯、肺痿、风血酒痢的区别，证候相同但病因不同。
泄痢需辨别积滞。泄痢有期限，或者久病依然如此，或者久病精神不憔悴的，适宜逐除积滞，这名叫滞下。
有一个六十岁的人，因忧虑患滞下痢，颜色褐色，腹部微痛，里急后重频繁发作，食欲大减，身体微热，脉象弦而涩，似乎数且稍长。这不是普通的滞下，而是由忧虑所致，心血亏虚、脾气虚弱。用四物汤、四君子汤合方治疗而痊愈。
有一个三十岁的人，生活优渥。秋天患滞下痢，腹部剧痛，左脉弦大似数，右脉也是这样，稍微减轻，重按时似乎紧。这是因为醉饱之后吃了寒凉食物，当作虚寒证治疗，于是用四物汤，去掉地黄，加入人参、白术、干姜，煎煮时加入姜汁、茯苓，一个月后康复。

[Pulse]
A pulse that is slippery but feels empty or imperceptible upon deep pressure indicates certain diarrhea (xià lì). If the cun position pulse is floating and rapid, while the chi position pulse is choppy, there will certainly be discharge of clear pus and blood. A sinking and wiry pulse indicates tenesmus (zhòng). If the pulse varies in size, the condition has not yet ceased. A rapid pulse accompanied by slight fever and spontaneous sweating indicates self-healing; however, if the pulse becomes tight again, the pathogen has not been resolved. A faint pulse that becomes rapid and stops diarrhea spontaneously indicates survival despite fever. A string-like pulse with fever and sweating also indicates self-healing. If the pulse disappears and the extremities are cold, life can be saved if warming moxibustion restores warmth to the hands and feet; if the pulse does not return and slight panting occurs, death ensues. A slow and slippery pulse indicates excess. If diarrhea persists, purgation is indicated. A rapid and slippery pulse indicates retained food, for which purgation is indicated. Discharge of white mucus from the intestine with a sinking pulse suggests survival, while a floating pulse suggests death. Discharge of pus and blood with an extreme or "hanging" pulse suggests death, while a slippery and large pulse suggests survival. A sinking, small, and continuous pulse suggests survival, whereas a rapid, large, and hot pulse suggests death. Intestinal cramping with an extremely rapid pulse suggests death. In all types of dysentery and projectile diarrhea, a sinking and small pulse suggests survival, while a floating and large pulse suggests death. Fever indicates death. Delirium or abdominal hardness and pain with a sinking and tight pulse can be treated with purgation; a slow pulse can be treated with warming methods. Dysentery with loss of appetite indicates retained food; fullness and pain in the intestines indicate cold-food retention; hardness in the intestines and epigastrium indicates excess, all of which can be treated with purgation. Dysentery with a slow pulse, abdominal pain, borborygmus, heart anxiety, and anal pain can be treated with warming methods. Dysentery caused by cold damage, where all three positions lack a pulse but the chi position occasionally shows a faint pulse that beats strongly when lifted, indicates that kidney qi remains. If the physical form is damaged and the pulse is absent, death ensues.
[Etiology]
From the perspective of wind-damp-heat, excessive fire damages metal (lungs), leaving wood (liver) overly vigorous and damaging earth (spleen). Mild cases present as undigested stool diarrhea with fever and a洪 (hóng) pulse, where food cannot be transformed; severe cases present with dysentery containing pus and blood. The Classics state: Wind injury in spring leads to undigested stool diarrhea in summer. Also: All diarrhea belongs to dampness. Also: Thick and sticky diarrhea belongs to fire. Also: Diarrhea with pus and blood belongs to dysentery (zhì xià).
[Syndrome Differentiation]
The aforementioned syndromes are all heat and excess patterns. It is contraindicated to use astringents such as Longgu (Fossilized Bones), Shizhi (Lithosi Fragment), and Qiaoke (Poppy Shell). Deficiency-type diarrhea involves water and grain that may or may not be digested, without straining efforts, only feeling fatigue and weakness, with a wiry and choppy pulse. This should be treated with warming and tonifying methods.
[Treatment]
For treatment, severe cases are primarily managed with Dahuang Tang (Rhubarb Decoction), and mild cases with Huangqin Shaoyao Tang (Scutellaria and Peony Decoction). Tenesmus requires purgation because it is caused by tangible pathogens causing obstruction and heaviness. Internal heat with a very 洪 pulse requires purgation; however, if the pulse is excessively 洪 and large, purgation is contraindicated. If the Large Intestine meridian qi is obstructed, add Mutong (Akebia Caulis), Binglang (Areca Seed), and Muxiang (Vladimiria Root). Intestinal pain requires harmonization; stomach qi disharmony is treated with Fuling (Poria), Danggui (Angelica Sinensis), and Shaoyao (Peony). Heaviness in the body requires dispelling dampness; a wiry pulse requires dispelling wind. If wind pathogen moves inward due to agitation, Dachaihu Tang (Minor Bupleurum Decoction) is used. Thick and sticky bloody pus requires heavy medication to exhaust it due to intense heat. Cold body with spontaneous sweating requires warming with toxic/hot medicines. Sudden profuse watery diarrhea without sound, cold body, spontaneous sweating, clear and frequent urination, involuntary defecation, difficult breathing, faint and sinking pulse, panting, and vomiting, even with tenesmus, indicates cold pathogen inside causing qi dispersion. Warming medicines like Jiangshui San (Fermented Grain Powder Powder) can stabilize this, belonging to the Shaoyin category. If wind pathogen contracts inward, sweating method is indicated. Jueyin dysentery with unceasing diarrhea, sinking and slow pulse, cold extremities, and pus/blood in sputum is difficult to treat; Mahuang Tang (Ephedra Decoction) and Xiao Xuming Tang (Minor Rescue Life Decoction) can be used to calm it. The method states: If exterior pathogen is trapped inside, disperse the exterior pathogen to resolve it. Li Dongyuan's lifting method is similar. Loose stools require warming. If diarrhea contains hard feces, it belongs to Taiyin. Interior excess requires purgation. Tenesmus, food stagnation, or qi sinking require purgation. Pathogens above require emesis. Phlegm-qiu above requires emesis to resolve; pathogens below require exhaustion/clearing. The general principle is: send off what goes (treat excess with draining), harmonize what is abundant, stop what is excessive. If aversion to cold/fever without abdominal pain, use Fuling as chief; severe pain adds Danggui and doubles Shaoyao. Blood presence adds Huanglian (Coptis); fever/aversion to cold requires Huangqin (Scutellaria) to stop, indicating upper jiao blood. Aversion to cold, sinking pulse, lower back pain, white dysentery pain, or blood requires Huanglian to stop, indicating middle jiao blood. Aversion to cold, sinking pulse, blood before stool requires Diyü (Sanguisorba) to stop, indicating lower jiao blood.
Dysentery involves wind, damp, heat, cold, and deficiency; dysentery (zhì xià), anorectic dysentery (jìn kǒu lì), childhood malnutrition dysentery (gān lì), consumption dysentery (zhài lì), and wet erosion sores share symptoms but differ in etiology. Bloody dysentery involves blood stasis, blood depletion, lung atrophy, wind-blood, and alcohol dysentery; they share symptoms but differ in etiology.
Differentiating Accumulation in Diarrhea/Dysentery: Diarrhea/dysentery with a specific duration, or chronic but spirit remains intact, requires expelling accumulation, named "Zhixia" (Stagnant Down).
Case 1: A 60-year-old man suffered brown stagnant dysentery due to worry, with slight abdominal pain, frequent tenesmus, reduced appetite, slight fever, and a wiry, choppy, slightly rapid and long pulse. This was not typical dysentery but caused by worry leading to heart blood deficiency and spleen weakness. Treated with Siwu Tang (Four Substances Decoction) and Sijunzi Tang (Four Gentlemen Decoction) combined, resulting in cure.
Case 2: A 30-year-old man with rich diet suffered autumnal stagnant dysentery with severe abdominal pain. Left pulse wiry-large-slightly rapid, right pulse similar but slightly less, heavy pressure felt tight. Caused by eating cold foods after drunken/full meals. Treated as deficiency-cold using Siwu Tang, removing Dihuang, adding Renshen (Ginseng), Baizhu (Atractylodes), Ganjiang (Dried Ginger), decocted with Jiangzhi (Ginger Juice) and Fuling, resolving in one month.
Huangqin Shaoyao Tang: Treats diarrhea/dysentery with abdominal pain, tenesmus, fever, and rapid洪 pulse.
