（俗名伤寒夹痢疾）
【因】痢疾古称滞下。皆由暑湿与食积胶固腑中。流行阻遏而成。或饱餐饭肉浓鲜之后。再食瓜果生冷。
令脾胃之血不行于四肢八脉。渗入胃肠而为痢。再复感表邪。如身热恶寒头痛。或染时疫成痢。或有外感
陷里而化痢。
【证】凡痢疾兼挟寒邪者。如下痢里急后重。腹有痛有不痛。恶寒头痛身热。或兼寒热恶心。舌苔浓腻。
口渴不食。变态多端。
【脉】痢脉微小滑利者吉。浮弦洪数者凶。浮大者未止。微弱者自愈。此无外感者。大旨如此。若兼表邪。初
痢身热脉浮者。先解表。初痢身热脉沉者。可攻下。久痢身热脉虚者。属正虚可治。久痢身热脉大者。属邪
盛难医。
【治】凡挟表邪之痢。与时行疫痢。皆有身热。但当先撤表邪。如恶寒头痛身热之类。因其表而行散之。表
邪解而痢亦轻矣。如仓廪汤。（人参、茯苓、甘草、柴胡、羌活、独活、枳壳、桔梗、川芎、薄荷、生姜、
陈廪米。）以解表化滞。自然身凉痢止。因于湿热者。以苦辛寒为治。苦以燥湿。寒以清热。稍加辛热佐之。
以为发散宣通之用。无不效矣。因于气者调之。因于血者和之。邵氏谓在气分、有苦辛调气。及辛甘益
气等法。在血分者、有苦辛行血。及咸柔养血诸方。治赤痢者。气分药必不可少。气行而血自止也。治
白痢者。血分药必不可兼。恐引邪入于血分。反变脓血也。此治痢者。不可不知也。
【秀按】痢疾一证。大都以赤者属热。白者属寒。然白色亦多属湿热者。如肌肉腐熟而成脓也。赤色
亦有属寒湿者。因血瘀凝涩而入肠也。不可据赤白分寒热。当以舌苔脉象辨之。大抵赤属血。自小肠来。
白属气。自大肠来。赤白相杂。气血俱病。盖心主血。肺主气。凝滞则伤气。郁热则伤血。气血既病。则
心肺亦病矣。而小肠者、心之合也。大肠者、肺之合也。二经皆出纳水谷。转输糟粕之官也。而胃又为大

白互下。其血与气之凝结。必挟饮食痰涎。始成积滞。其饮食痰涎。皆聚于胃。故痢证亦不离乎胃。谓由心
肺而及于胃也。此辨致痢之原因也。再详证候。以定疗法。所云里急后重。其证在广肠最下之处。里急与
后重不同。里急者、急迫欲便。后重者、肛门重坠。里急有虚实之分。实为火邪有余。虚为营阴不足。里
急而不得便者火也。重者承气汤。轻者芍药汤。久病见之为气脱。里急而至圊反不能出者。气滞也。以疏
通为主。后重亦有虚实之异。实为邪实下压。虚由气虚下陷。因邪压大肠。大肠不能升上。而下坠乃后
重。宜大黄槟榔、或香连丸。泻其所压之邪而愈。若积滞已行。后重不减。脉无力。不食者。此脾气下
陷。或大肠虚滑。不能自收。治以升涩之剂。固其脱。升其坠而愈。二者何以辨之。凡邪迫而后重者。
至圊稍减。未甚复甚。（荣斋按∶未甚复甚句不大明了，或许是未
几复甚之误。）虚滑而后重者。圊后不减。而得解愈虚故也。亦由积滞已去。过服肉面生冷而后重者。运脾消

乃阳气不升。药中当加升麻升其阳。其重自去也。至于腹痛。亦有寒热虚实之不同。实痛者、非食积即火邪。
食必痛而拒按。若脉洪实有力。腹胀坚硬。为积滞作痛。若火则畏热喜寒。脉洪而数。口渴喜冷。兼见热证。
为火邪作痛。邪实于中。每多气逆。故治痛之法。皆以行气为主。食则消之。火则清之。丹溪云。初病得之亦

【荣斋按】本节廉臣先生勘语，是指湿热痢、虚寒痢而言，不是指夹伤寒的痢。他在《名医验案类编》中，
却帮助了伤寒夹痢的治法，特录于下∶“痢疾见头痛怕冷，身热无汗者，均属有表，当从汗解。如口舌不燥
渴，胸腹不闷痛，舌或无苔，或淡白且滑，宜活人败毒散（茯苓、枳壳、桔梗、柴胡、羌活、独活、川芎各一
两，甘草五钱加薄荷少许。）每服五钱，日夜连进三五服，姜汤煎，热服取汗，汗透而痢便减。若见燥渴，
唇舌红赤，舌上黄燥或滑，面色腻滞，心烦，小便热赤者；为湿热暑湿之邪，宜胃苓汤（苍术、浓朴、陈皮、
甘草、白术、泽泻、猪苓、茯苓、官桂。）去官桂，加香薷、薄荷、连翘、滑石、淡豆豉，六神曲等；连
进三五服，得汗透而痢自止。”这治法是针对“夹痢伤寒”而设，移作补充，更见完备。
(Also known as Cold Damage complicated with Dysentery)
[Etiology] Dysentery was anciently called "Zhi Xia" (Stagnant Downward Flow). It is generally caused by the entanglement of Summerheat-Dampness and food retention in the intestines, obstructing the flow of Qi. Alternatively, after a heavy meal of rice, meat, and rich/fresh foods, consuming raw or cold fruits and vegetables causes the Qi and Blood of the Spleen and Stomach to fail to circulate normally to the four limbs and all meridians, seeping into the stomach and intestines to become dysentery. Subsequently, exterior pathogens are contracted, presenting with fever, aversion to cold, and headache; or it may be contracted from seasonal epidemic pathogens becoming dysentery; or exterior pathogens may sink inward and transform into heat, resulting in dysentery.
[Signs and Symptoms] In cases where dysentery is complicated by Cold pathogens, symptoms include tenesmus (urgent desire to defecate with a feeling of incomplete evacuation), abdominal pain that may or may not be present, aversion to cold, headache, fever, or alternating chills and fever with nausea. The tongue coating is thick and greasy, there is thirst but no desire to eat, and the condition varies greatly.
[Pulse] A pulse that is fine, small, slippery, and smooth indicates a good prognosis for dysentery. A floating, wiry, surging, or rapid pulse indicates a poor prognosis. A floating and large pulse suggests the disease will not cease; a weak and thready pulse suggests spontaneous recovery. This applies to cases without exterior pathogens. Generally speaking: if dysentery is accompanied by an exterior pathogen, and in the early stage there is fever and a floating pulse, the exterior should be resolved first. If in the early stage there is fever and a deep pulse, purgation may be used. In chronic dysentery with fever and a deficient pulse, it belongs to deficiency of healthy Qi but is treatable. In chronic dysentery with fever and a large pulse, it belongs to excess of pathogenic factors and is difficult to treat.
[Treatment] For dysentery complicated by exterior pathogens, similar to seasonal epidemic dysentery, there is fever. However, the exterior pathogen must be resolved first, addressing symptoms like aversion to cold, headache, and fever. Following the nature of the exterior pathogen, disperse and scatter it. Once the exterior pathogen is resolved, the dysentery will also lighten. For example, Canlin Tang (Ginseng Decoction [Ren Shen, Fu Ling, Gan Cao, Chai Hu, Qiang Huo, Du Huo, Zhi Ke, Jie Geng, Chuan Xiong, Bo He, Sheng Jiang, Chen Lin Mi]) resolves the exterior and transforms stagnation, naturally leading to cooling of the body and cessation of dysentery. For cases due to Damp-Heat, treat with Bitter-Pungent-Cold herbs. Bitter herbs dry Dampness, and Cold herbs clear Heat. Add slightly Pungent-Hot herbs as assistants to facilitate dispersion and circulation. This method is invariably effective. For disorders of Qi, regulate Qi; for disorders of Blood, harmonize Blood. Mr. Shao stated that for disorders in the Qi level, use Bitter-Pungent methods to regulate Qi, and Pungent-Sweet methods to benefit Qi. For disorders in the Blood level, use Bitter-Pungent methods to move Blood, and Salty-Soft methods to nourish Blood. When treating red dysentery, Qi-regulating herbs are indispensable because moving Qi stops Blood. When treating white dysentery, Blood-harmonizing herbs must be avoided to prevent drawing pathogens into the Blood level, which could worsen pus and blood. This is crucial knowledge for treating dysentery.
[Commentary by Xiu] Dysentery is generally considered Red as Heat and White as Cold. However, White often belongs to Damp-Heat, resembling rotting flesh turning to pus. Red can also belong to Cold-Damp, due to Blood stasis and stagnation entering the intestines. One cannot distinguish Cold/Heat solely by color; one must examine the tongue coating and pulse. Generally, Red belongs to Blood and originates from the Small Intestine; White belongs to Qi and originates from the Large Intestine. Mixed Red and White indicates both Qi and Blood are diseased. Heart governs Blood, Lung governs Qi. Stagnation injures Qi, Stagnant Heat injures Blood. Once Qi and Blood are diseased, Heart and Lung are affected. The Small Intestine is the interior-exterior pair of the Heart; the Large Intestine is the interior-exterior pair of the Lung. These two meridians are officials responsible for receiving/transmitting water/grain and transporting waste. The Stomach is the general manager of the Small and Large Intestines. Disease transferring from Lung to Large Intestine causes Qi stagnation/stiffness, resulting in White Dysentery. Disease transferring from Heart to Small Intestine causes Blood stagnation/stiffness, resulting in Red Dysentery. If both intestines are diseased, Red and White pass together. The coagulation of Blood and Qi must carry dietary retention and phlegm-fluids to form stagnation. These dietary retentions and phlegm-fluids gather in the Stomach; thus, dysentery is never separate from the Stomach, implying pathology moves from Heart/Lung to Stomach. This analyzes the cause of dysentery. Further analyze signs/symptoms to determine therapy. Regarding "tenesmus," the pathology is at the lowest part of the Rectum (Guang Chang). "Li Ji" (internal urgency) and "Hou Zhong" (anal heaviness) are different. Li Ji is urgent desire to defecate; Hou Zhong is heavy bearing down sensation. Li Ji has Deficiency/Excess types: Excess is surplus Fire pathogen; Deficiency is insufficiency of Ying-Yin. Urgency without ability to defecate is Fire; severe cases use Chengqi Tang, mild cases use Shaoyao Tang. Chronic appearance indicates Qi collapse. Urgency but inability to pass stool at the toilet indicates Qi stagnation; treat primarily with unblocking. Hou Zhong also has Deficiency/Excess differences: Excess is pathogenic pressure downward; Deficiency is Qi sinking. Pathogenic pressure on Large Intestine prevents lifting, causing bearing down; use Da Huang, Bing Lang, or Xianglian Wan to purge the pressing pathogen. If stagnation has passed but Hou Zhong persists, with weak pulse and anorexia, this is Spleen Qi sinking or Large Intestine deficiency/slippage unable to contract; treat with lifting and astringent agents to secure collapse and lift sinking. How to differentiate? If Hou Zhong is due to pathogenic pressure, it lessens slightly after defecation but returns severely shortly after (Rongzhai notes: "returns severely shortly after" might be a typo for "not long after"). If Hou Zhong is due to deficiency/slippage, it does not lessen after defecation and worsens due to further depletion. Also, if Hou Zhong occurs after stagnation clears and overconsumption of meat/noodles/raw-cold foods, treat primarily with Spleen-moving and digestion-promoting methods. However, empty straining without stool indicates Blood deficiency; double the dose of Siwu Tang, add Xinhui Pi (Chen Pi), harmonize Stomach, generate Blood, and peace will return. If Hou Zhong persists after dysentery, use Sanqi San (Zhi Ke, Huang Bo, Fang Feng), which is excellent. If passing pus/blood, tenesmus, frequent day/night, or thirst, use Daoqi Tang (Bai Shao, Da Huang, Gui Wei, Huang Qin, Huang Lian, Mu Xiang, Zhi Ke). If passing mixed red/white, tenesmus, use Xianglian Wan or Muxiang Binglang Wan, selecting based on syndrome differentiation. For cold-heat imbalance, tenesmus, abdominal pain, thirst, and difficult urination, use Huanglian Ejiao Wan (Huang Lian, Ejiao, Fu Ling; remove Fu Ling, add Huang Bo, Shan Zhi; named Huanglian Ejiao Tang by Haicang). Tenesmus requires regulating Qi. If accumulation and Qi sink together, combine lifting and dispersing. After using Chengqi-type purgatives, if tenesmus persists, Yang Qi is not ascending; add Sheng Ma to lift Yang, and heaviness will resolve. Abdominal pain also varies by cold/heat/deficiency/excess. Excess pain is either food retention or Fire pathogen. Food retention causes pain and refusal of pressure; if pulse is surging/excessively strong with hard distension, it is stagnation pain. Fire pathogen fears heat/likes cold, pulse is surging/rapid, thirst likes cold, with heat signs; this is Fire pain. Excess pathogens in the middle often cause Qi rebellion; thus, pain treatment focuses on moving Qi. Resolve food retention, clear Fire. Danxi said early onset can use Dachengqi Tang or Tiaowei Chengqi Tang. Assess Qi vs. Blood disorder, then modify. For dysentery pain relief, use Rushen Tang (Chuan Lian, Zhi Ke, Huai Hua) or Shaoyao Gancao Tang (Bai Shao, Gan Cao). For heat pain, add Huang Qin, Huang Lian. For deficiency-cold pain, warm the viscera is suitable. Cold in Middle Jiao warms Spleen; Cold in Lower Jiao warms Kidney. Differentiate by refusal/appreciation of pressure and preference/dislike of cold. Insisting on "no tonification for pain" ignores deficiency pain; attacking more increases deficiency and pain. Ancients said dysentery followed by diarrhea (Kidney to Spleen) is easy to treat; diarrhea followed by dysentery (Spleen to Kidney) is hard to treat. Ye Tianshi said Mingmen Fire decline causes diarrhea, not dysentery. Also, Cold has no upward-pushing nature; Fire is rapid, hence downward pushing. Spleen/Kidney Qi deficiency causes diarrhea. Summer/Autumn dysentery is mostly Damp-Heat pushing downward. Tonifying Spleen/Kidney is only for chronic diarrhea without stagnation/abdominal pain, not for Summer/Autumn dysentery. Do not lightly use astringents; early astringency retains stagnation, leading to death. Use Ren Shen, Huang Qi cautiously; misuse causes distension. Misuse of Sheng Ma causes Jin Kou Li (Anorexic Dysentery). Only appropriate for Qi sinking; otherwise, Lower Jiao Damp-Heat/stagnation rises to Upper Jiao, causing rapid death. Avoid oily foods, alcohol, noodles. Alcohol during dysentery hinders cure; after cure, triggers recurrence. Most dangerous is Jin Kou Li. Early Jin Kou Li is usually Damp-Stasis-Heat depression, Stomach Qi trapped/not diffusing, Spleen Qi stagnant; use Xianglian Zhipu type to clear/disperse gut. If filth below steams turbidity, purge it, e.g., Xianglian plus Da Huang. Chronic Jin Kou Li indicates exhausted Stomach Qi; Duhuo, Lizhong Tang are insufficient. If pulse is fine/weak, use Renshen Baizhu San (Ren Shen, Fu Ling, Bai Zhu, Bian Dou, Shan Yao, Yi Yi Ren, Jie Geng, Chen Pi, Sha Ren, Lian Rou, Gan Cao, Da Zao) plus Chang Pu powder, taken with rice drink. Shen Jinao said Shi Chang Pu treats Jin Kou Li effectively. Ancients said Stomach deficiency with Fire: Danxi used Ren Shen, Chuan Lian, Shi Lian, Jing Mi, plus Ginger Juice, sipped slowly. If vomited, re-administer. Or use Ginger-fried Chuan Lian with Ren Shen decoction. Ye's Banxia Xiexin Tang, removing Da Zao/Gan Cao (middle-harmonizing items). There is also Resting Dysentery (Xiuxi Li), recurring repeatedly over years, not fully cured. Often due to early astringency, unresolved Damp-Heat, improper care, or irregular diet injuring organs, endless duration. Buyi Yiqi Tang is best, possibly adding Rou Guo, Mu Xiang, swallowing Zhuche Wan. For Yin deficiency with much Fire, unable to tolerate Sheng Ma, Mu Xiang, Bai Zhu, use only Zhuche Wan plus Ren Shen, Wu Mei. With retention, add Zhi Shi, Zha Tan. With unresolved retention-heat, use Qingliu Wan (Hua Shi, Gan Cao, Hong Qu) plus Xianglian. Post-Malaria Dysentery, Dysentery post-Malaria, or simultaneous Malaria-Dysentery. Post-Malaria dysentery implies exterior pathogen sinking or Yuan Qi sinking; this resembles dysentery but isn't true dysentery. Overeating meat/noodles can cause post-malaria dysentery; use Ge Gen, fried Mai Ya, Liu Shen Qu to transform. Post-dysentery malaria implies pathogen exiting outward; guide it out according to its mechanism. Simultaneous onset requires exclusive dispersing: Jing Jie, Fang Feng, Chai Hu, Ge Gen, assisted by Chi Fu Ling, Shen Qu. For blood dysentery, add Dang Gui, Chuan Xiong to lift pathogen from Fu organs to Jing meridians for exterior resolution. If ineffective, differentiate Cold/Heat, resolve exterior/interior separately. Heat: remove Jing/Fang, add Qin/Lian. Cold: remove Chai/Ge, add Gui/Jiang. Differentiate dysentery complications. Vomiting with dysentery indicates Stomach disharmony; add Ginger-fried Chuan Lian, Zhu Ru, Guang Yu Jin. Deficiency: add Ren Shen. Resolve food, transform phlegm. Dysentery with urinary obstruction: interior Heat pathogen presses Large Intestine, stagnates in Bladder, Qi fails to transform. Clear Bladder Heat, assist Lung Qi. Yu Shi's method of "opening side channels" promotes Qi transformation and clears Heat. True Heat presents with painful/scanty urination; mild cases use Liuyi San, taken with cool water. Anal pain: differentiate new/old, cold/heat. Heat lingering below: Huangqin Shaoyao Tang clears it. Deficiency-cold pain: Lizhong Tang warms it. Diet should be bland. Fumigation method: burn Shu Ai, Huang La, He Zi for smoke inhalation. Heat causes anal closure; Cold causes prolapse. Thus, prolapse is mostly deficiency-cold, rarely excess-heat. Chronic cold-slippage prolapse: use Hezi Pi San (He Zi, Su Qiao, Pao Jiang, Ju Hong), take Ci Shi powder with rice drink before meals. Wash anus with Iron Rust Soup. Hiccups after dysentery indicate Stomach deficiency-cold, a bad omen. Jupi Ganjiang Tang (Chen Pi, Gan Jiang, Zhu Ru). Hiccups from raw/cold food: Lizhong Tang plus Ding Xiang. This is Xiu's accumulated experience, referencing Wu Yunfeng's insights.
[Review by Lian] Cold Damage transforming into dysentery, and dysentery transforming into Cold Damage. Since it involves lower dysentery, one must distinguish the color of the discharge and correlate with external signs to avoid misdiagnosis. Early stage tenesmus, white discharge: Damp-Heat stagnation, Qi level pathogen. Use Weiling Tang plus Xiang Sha. With Heat: add fried Huang Qin, Hua Shi. Color like bean juice: Spleen Damp-Heat, dry Spleen, separate fluids; Weiling Tang is primary. Like fish brain or mucus jelly: Spleen deficiency Cold Dysentery. Use Er Zhu, Pao Jiang, etc. White pus with straining: Qi and Heat knot. Use Mu Xiang, Bing Lang, Huang Qin. Like roof leak water or dust/rot color: Vital Qi exhaustion. Use Lizhong Tang, add Wei Ge Gen, fried Huang Qin, Fu Ling. Red dysentery is Blood level pathogen. Mostly Damp-Heat: move Dampness, clear Heat. Fried Huang Qin, fried Jin Yin Hua, Hua Shi, Mu Xiang, Zha Tan. With purple clots or sticky texture: Huang Qin, Yan Hu Suo, Tao Ren, Chi Shao, move stasis. Bright fresh/purple-concentrated blood: Excess Heat. Use Baitouweng Tang. Early severe stage, tenesmus, strong pulse: add processed Da Huang to purge. Pure clear blood, wiry pulse: Wind entering Stomach. Use fried Zhi Ke, Jing Jie Tan, Wei Fang Feng. Purple-dark blood, worsening with cold meds: Cold-Damp. Use Lizhong Tang, add Chuan Xiong, Dang Gui, Mu Xiang. Like pig liver or amaranth juice: Cold. Requires Pao Jiang. Pale/thin blood or agate color: Yang deficiency failing to control Yin. Must warm/regulate Qi to clear Blood. Yellow/Black colors: Deep yellow foul odor: Heat. Light yellow pale slight odor or fishy/sour: Cold. Black scorched thick strong odor: Fire. Black shiny lacquer-like: Blood stasis. Blue-black thin fishy: Liver/Kidney corruption. Five-color dysentery has deficiency/excess. Danxi said food retention in Spleen/Stomach plus four Qi merging causes five-color mixing. First purge/unblock, use Guilian Wan (Dang Gui, Huang Lian, Huang Bo, Huang Qin, Ejiao, Shu Ai). Some due to internal Damp-Toxin excess. Ma Yuanyi said five-color dysentery injures Qi transformation of five Zang organs; treatment seeks Kidney, as Zhang Zhongjing described "five fluids pouring down." Benefit Fire, eliminate Yin, solidify Spleen, dam Water, regulate Qi separately, perhaps save one in ten thousand. Zhang Sanxi said bad syndromes of various dysenteries, chronic pus/blood, or dead pig liver color, or mixed five colors, vulgarly "scraping intestine dysentery," indicates total organ deficiency, Spleen Qi collapse. Further dysentery drugs are errors; use Zhenren Yangzang Tang. Generally, dysentery is Interior syndrome, do not expect Exterior Heat like headache/fever. If exterior heat exists, interior/exterior are both distressed. Thus Yu's method prioritizes resolving exterior pathogen to clear dysentery, exemplifying key points.
[Rongzhai Note] Mr. Lianchen's review here refers to Damp-Heat Dysentery and Deficiency-Cold Dysentery, not Cold Damage complicated with dysentery. In "Mingyi Yan Lei Bian," he aids the treatment of Cold Damage complicated with dysentery, recorded below: "Dysentery with headache, aversion to cold, fever, no sweating: all indicate exterior pathogen, resolve via sweating. If mouth/tongue not dry/thirsty, chest/abdomen not stuffy/painful, tongue no coating or pale/white/slippery: use Huoren Baidu San (Fu Ling, Zhi Ke, Jie Geng, Chai Hu, Qiang Huo, Du Huo, Chuan Xiong 1 liang each, Gan Cao 5 qian, plus little Bo He).
