正阳阳明。
舌苔微黄，正阳阳明。舌苔前白后黄，正阳阳明。（按∶是上寒下热，外寒内热。）前黄后白，正阳
阳明。（按∶是上脘化热，而中焦有水饮。）四围白，中间黄，正阳阳明。白带灰色，阳明
将入太阴。白带有路，阳明太阴。微白燥黄色，阳明太阴。粉白微红，阳明少阳。无白微桃红，阳明少阴。

以上三十五法，乃辨证之大略，余照此类推之可也。
广东、福建、浙江、江南扬州分野，鱼盐海滨之地，肠胃脆薄，气盛血热，所以风邪一客即病。头虽痛，
不如斧劈，项虽强，尚可转侧，背虽牵制，尚可动摇。风邪入胃，肺则凝塞，所以一日为风，二日为热，三日
为火，热甚之故。热与风邪相搏，凝塞成毒。此毒，胃主肌，脾主肉，不在肉而在肌。肌，毛窍之内也。故
点点然如斑之状，如疹之形，红色鲜明，一日三潮，三日九潮，故毒必三日，虽不治，
亦疏散也。脉左寸浮，右关滑，气口大。无有正伤寒也。故太阳经虽病不病，此阳明之正病也，谓之阳明
太阳。舌苔白，一日不口渴，二日不大便，至三四五六日，大便解，则腠理开。汗出而解。
如阳明第四日，血热成毒，不能发越，毒郁在中，腠理不开，郁遏邪热，则传入少阳。一日口渴，左
关洪大，右关洪滑，右寸气口闭遏，此肺经热邪冲遏，气道不舒，斑在肌腠，血凝在皮，少阴虽然受热，而
未尝着病。二日目赤，舌苔红，耳鸣，左关脉洪大而数，此热甚邪胜也。第三日谵语，不欲眠，右关洪滑
而实。四日斑出则少解，斑不出狂叫不安，右关滑实有力，左关脉洪数微弦，左尺脉虚大，此邪
气将入于里。第五日耳聋，不欲眠，起坐不休，谵语欲狂，此斑毒不得发越，口干消水，舌苔红黄色，邪尚
未曾传里也；舌苔红紫色，将入于脾。左关弦，右关实，乙木怒极，热郁之甚。耳聋，肾之火闭也。斑毒出
于胸项脊背，此阳邪有余，隐于胸项脊背，此阳毒将陷入阴分。六日大便解，邪气得下，斑必发出；六
日不解，火气闭于幽门，小便短涩，毒反熏胃，肺闭，大肠热，目直视，不欲见人，脉数，舌焦。
邪传太阴，目黄，面黄，此风胜湿郁，第七日耳聋，口渴，
目黄，两颊黄赤，舌苔焦，脉与六日同，此病尚在阳分未除，邪虽入里，犹可挽回。
少阳不得解，邪传入里，流入太阴脾经。一日右关洪大而软，左关弦动，左寸闭，此热邪客于包络，
神昏气短，白珠红，肺经郁抑，斑毒则颈项上见者红色，两颊无有，心胸不见，季胁有微点，腹上点点红色，
手臂前俱有红色，舌苔黄黑，虽然传里，阳证未除。二日右寸见弦脉，风邪客于肺，将发白斑，气促者死，鼻
扇者死，耳聋者生，面颊红者生，闭目不欲见人者生，鱼口鸦声者死。第三日右关数，左
寸不见，右尺洪大，此邪热客于肾，唇紫，舌焦黑，目直视，不欲见人，此毒郁于小肠，燥粪不得下，斑隐
在肉内，怒狂叫骂者生，口渴消水者生，小便不滋润者死。第四日左寸闭，左关弦，左尺洪大，右关虚软，
右寸见芤脉，右尺不见，血热在中焦，斑见蓝色。第五日左右手寸关脉不见，两尺洪大，声嘶欲哭，斑郁不得
发越，目黄身黄者死。第六日尺寸俱无，两关弦紧，舌苔湿滑，此火甚感寒，头凉即死，舌苔燥裂，仍为火论。
或阳明第五日斑发不透，邪毒不入少阳，竟入太阴，此非越经传也，或饮食所伤，或药饵所误。太阴一二
日，季胁痛，下痢，左关弦软，右关弦长，气口脉洪，尺脉大，口渴甚，嘴唇干，舌燥，神气清，舌苔黄浓，
黑灰色。第三日舌根黑，中黄，尖白，目赤面青，左关脉数，右关滑大有力，肺脉大，两尺脉闭，头面有斑，
颈项无斑，胸背有斑，肚腹无斑，此阳气不得发越，阴气凝塞。太阴四日，左三部闭，
右关软，肺脉大，尺脉洪，口渴甚，目红，面赤，鼻青，唇
黑者死，伏斑下陷。太阴五日，尺寸俱浮，右关芤，左关紧，
时作寒战，头痛，目赤，鼻黑，舌青，唇紫者死，斑毒乘于肝，非传厥阴，邪中厥阴也。
太阴之脉，利于无力，邪入于脾，气盛血热，流于四肢，分布百骸，贯注于心，心神失专其权，是以
相火之邪甚炽，心神与相火失位，则一身无所主矣。故四肢百骸俱痛，腹满口干，舌黄舌黑，唇燥，五脏与
大小肠膀胱三焦皆受其制。脉之细小者，胃气不伤，脉之滑大者，胃气已坏。胃主纳谷，脾主消谷∶胃主
受纳，脾主转濡；胃之受纳在于肺，脾之转濡在乎肝。在上者为痰，在下者为糟粕。膈气实则痰滞
于膻中，心气热，则糟粕滞于小肠。渴欲饮冷者，膈气热也。饮水不小便者，肺叶焦也。肺气盛者，则大肠
之道不行。夫邪在阴分，不利见阳脉；病在阳分，不利见阴脉。太阴之病，利于细小虚软，不利于洪大滑实。
通其经络，导其闭塞，毋使风木成邪，致人九窍不通而死。太阴之脉，非独取右关，左寸左关右尺皆可概
见也。独肺居华盖，肺气凝涩，更利于细小，不利于实大。与正伤寒之病，传入太阴，皆脉大者病进，脉
小者病退，有力者病进，无力者病退；滑实者病进，虚软者病退；紧实者病进，芤软者病退，洪数
者病进，细软者病退。
如病之外现，目红面红，舌红唇红，手足摇动，坐立不宁，舌苔焦黑，此毒邪炽盛，脉见细小，此皆有
胃气，不可谓不治也。如目青面青，唇青舌白，脉见微细者，毒瓦斯下陷，将出汗而死矣。太阴病，面赤目赤，
唇紫舌黑，两关见数脉者危，见促脉者死。面白目赤，鼻青唇青，舌苔灰色，左尺右
关见紧脉者死。目赤面黄，鼻扇唇青，右寸见数脉，关脉见
弦脉，两尺不应者死。神气如常，舌苔微黑，两关见革脉者死。舌黄目青，面白唇白，脉见微弱，手足厥冷，
身发白斑者死。舌光如镜，目红面青，两关洪大，两尺洪数，两寸不应，毒陷下焦，颈项斑不出者死。舌上
芒刺，苔色灰黑，腹胸胀满，渴甚不欲饮水，右寸见极，右关见软，左关见涩，结胸者死。舌尖平，季胁痛，
舌苔焦黑，时下清水，口渴不欲饮汤水，左尺见结，左寸见代，右关见牢，热结小肠死。
舌苔黄白，点点红紫，唇青，面白，目赤，左关见软，右关见涩，肺脉不应者死。舌苔浓白，上灰黑色，脾
部干燥，唇红，目赤，面白，两尺不应，左关见软，右关沉实，两寸不应，颈项发白斑者死。舌苔红紫，目赤
面黄，唇干胸满，神气昏沉，手足厥冷，右关不应，左关弦紧，左尺空大，斑毒陷下者死。舌焦圆浓，华池干
燥，唇焦齿黑，目红面赤，神气昏愦，脉见细小，频叫，不知人者死，知人者可生。大便
频解，不知人者死；大便频解，渐知人者可生。舌不退场门，发战者死。大便解后，舌不润转者死不治。大便
解后，神气倏清，舌虽润，即出汗者死。大便解后，脉见狂大，必定血从口鼻出，急服更衣散一服，使肝分
得凉，藏血可生，如迟，吐血必死。夫病至太阴，死证已多；若传入少阴，则邪盛正衰，危者十九，死者
亦多；传入厥阴，则风木成邪，九窍将闭，不必为之细论矣。（此篇所论，与温病相出入，先生亦谓非正伤寒病也。）
凡舌红面赤，而两手见阴脉，或脉来摇摆无根，恍惚难凭，舌上肝胆部位，有一点点紫泡如黄豆大者，
此热毒归脏，不治之证。在左者重，在右者轻，在中间而不在肝胆部位者更轻，察其脉，可救者，须救之。（旧
谓舌边缺如锯齿者死，即此义也。）
From Hu Yuhai's *Shanghan Yishu* (A Book on Cold Damage), the main purport is to discuss that damp-warmth disease belongs to the latter half of the course of cold damage.
Headache, body heat, aversion to cold, and floating-slippery pulse indicate concurrent involvement of the Yangming and Taiyang meridians. Body heat, dry mouth, and wiry-slippery pulse indicate concurrent involvement of the Yangming and Shaoyang meridians. Body heat, white tongue coating, and surging-slippery pulse indicate Zhengyang Yangming disease.
Slightly yellow tongue coating indicates Zhengyang Yangming disease. White coating at the front and yellow at the back indicates Zhengyang Yangming disease. (Note: This represents cold above and heat below, exterior cold and interior heat.) Yellow coating at the front and white at the back indicates Zhengyang Yangming disease. (Note: This indicates heat transformation in the upper jiao while fluid retention exists in the middle jiao.) White coating surrounding and yellow in the center indicates Zhengyang Yangming disease. White coating with gray tints suggests Yangming disease is about to transmit to the Taiyin meridian. White coating with distinct patterns involves both Yangming and Taiyin. Slightly white and dry-yellow coating involves Yangming and Taiyin. Pinkish-white with slight redness involves Yangming and Shaoyang. Absence of white with slight peach-red hue involves Yangming and Shaoyin.
Redness at the front half and whiteness at the back half involves Shaoyang and Taiyin. Redness at the front half and yellowness at the back half involves Shaoyin and Taiyin. Yellowness at the front half and blackness at the back half involves Yangming and Taiyin. Yellowness at the front half and redness at the back half involves Taiyin and Shaoyin. Yellowness at the front half and purpleness at the back half involves Taiyin and Jueyin. Purely black coating indicates Taiyin disease. Purely yellow coating indicates Taiyin disease. Eight variations of yellow coating involve Yangming and Taiyin. Half yellow and half white involves Yangming and Taiyin. Half black and half yellow involves Yangming and Taiyin. Scorched-black coating indicates Taiyin disease. Moist-black coating indicates Taiyin disease. Mottled yellow-gray-black coating involves Yangming and Taiyin. Purely red, mirror-like coating indicates Taiyin disease. (If the tongue surface is glossy like a lacquered table, bright but not moist, and the Huachi under the tongue is completely dry, the condition is severe. Careful examination is required.) A thick tongue resembling three "nong" characters indicates Shaoyin disease. A wide tongue resembling three "kuo" characters indicates Shaoyin disease. A round tongue indicates Shaoyin disease. A flat tongue without a tip indicates Shaoyin disease. (Note: Old texts state that a tongue edge missing like saw teeth indicates death.) White coating with a tiny bit of red involves Yangming and Shaoyang. White coating with a tiny bit of black involves Yangming and Taiyin. White coating with a tiny bit of yellow indicates Zhengyang Yangming disease. Red tip and red back involves Shaoyin and Shaoyang. Red tip and purple back involves Shaoyin and Shaoyang.
The above thirty-five methods are general principles for differentiation; others can be inferred by analogy.
In Guangdong, Fujian, Zhejiang, and Jiangnan Yangzhou regions, which are coastal areas of fish and salt, people have fragile intestines and stomachs, abundant qi, and hot blood. Thus, wind pathogen causes disease upon invasion. Although there is headache, it is not as severe as an axe blow; although there is neck stiffness, turning is still possible; although there is back tension, movement is still possible. Wind pathogen enters the stomach, causing lung qi stagnation. Therefore, day one presents as wind, day two as heat, and day three as fire, due to intense heat. Heat and wind pathogen struggle, condensing into toxin. This toxin affects the muscle layer governed by the Stomach, rather than the flesh governed by the Spleen. The muscle layer is within the hair pores. Hence, spots appear dot-like like macules or papules, bright red, occurring in tidal waves three times a day, nine times over three days. Thus, the toxin must pass through three days; even without treatment, it will disperse. Pulse: Left Cun floating, Right Guan slippery, Qi Kou large. This is not typical Shanghan. Thus, although the Taiyang meridian is affected, it is not the primary pathology; this is the proper pathology of the Yangming meridian, called Yangming-Taiyang. Tongue coating white, no thirst on day one, no bowel movement on day two. By days three to six, when stool passes, the couli open. Relief comes with sweating.
If on the fourth day of Yangming disease, blood heat forms toxin that cannot vent, toxin stagnates in the middle, couli do not open, trapping evil heat, then it transmits to the Shaoyang meridian. Day one: thirst, Left Guan surging-large, Right Guan surging-slippery, Right Cun Qi Kou blocked. This is lung meridian heat pathogen blocking, airway discomfort. Macules are in the muscle-couli, blood coagulates in the skin. Shaoyin receives heat but is not diseased. Day two: red eyes, red tongue coating, tinnitus, Left Guan surging-large-rapid. This indicates intense heat and victorious evil. Day three: delirious speech, desire not to sleep, Right Guan surging-slippery-excessive. Day four: if macules appear, symptoms ease; if not, manic screaming and unrest. Right Guan slippery-excessive-forceful, Left Guan surging-rapid-slightly wiry, Left Chi empty-large. This indicates evil pathogen entering the interior. Day five: deafness, desire not to sleep, restless sitting/standing, delirious speech nearing madness. This is macule toxin unable to vent, dry mouth consuming fluids. Tongue coating red-yellow, evil has not yet transmitted to the interior; tongue coating red-purple, about to enter the Spleen. Left Guan wiry, Right Guan excessive, Liver Wood angry extreme, heat stagnation severe. Deafness is closure of Kidney Fire. Macules emerging from chest, neck, spine indicate excess Yang evil hiding in these areas; this is Yang toxin about to sink into Yin divisions. Day six: stool passes, evil descends, macules must emerge; if not resolved by day six, fire closes at Youmen, urine short/astringent, toxin steams the Stomach, Lung closed, Large Intestine hot, eyes fixed staring, desire not to see people, pulse rapid, tongue scorched.
Evil transmits to Taiyin, yellow eyes, yellow face, indicating wind dominance and damp stagnation. Day seven: deafness, thirst, yellow eyes, yellow-red cheeks, scorched tongue coating, pulse same as day six. Disease remains in Yang division unremoved; although evil entered interior, it can still be rescued.
Shaoyang unresolved, evil transmits interior, flowing into Taiyin Spleen meridian. Day one: Right Guan surging-large-soft, Left Guan wiry-moving, Left Cun blocked. Heat pathogen lodges in Pericardium, mental confusion, short breath, white of eyes red, Lung meridian depressed. Macule toxin appears red on neck, absent on cheeks/chest, micro-points on hypochondrium, red dots on abdomen, red on anterior arms, tongue coating yellow-black. Although transmitted interior, Yang syndrome remains. Day two: Right Cun wiry, wind pathogen lodges in Lung, white macules about to emerge. Panting indicates death, nasal flaring indicates death, deafness indicates survival, red cheeks indicate survival, closing eyes avoiding people indicates survival, fish-mouth crow-voice indicates death. Day three: Right Guan rapid, Left Cun absent, Right Chi surging-large. Heat pathogen lodges in Kidney, purple lips, scorched-black tongue, fixed staring, avoiding people. Toxin stagnates in Small Intestine, dry feces cannot descend, macules hidden in flesh. Manic screaming/cursing indicates survival, thirst consuming water indicates survival, non-moist urine indicates death. Day four: Left Cun blocked, Left Guan wiry, Left Chi surging-large, Right Guan empty-soft, Right Cun knotted-pulse, Right Chi absent. Blood heat in Middle Jiao, macules appear blue. Day five: Left/Right Cun/Guan pulses absent, both Chi surging-large, hoarse voice wanting to cry, macule toxin stagnant unable to vent. Yellow eyes/body yellow indicates death. Day six: Cun/Guan all absent, both Guan wiry-tight, tongue coating wet-slippery. Fire extreme sensing cold; head cool indicates death. Tongue coating dry-cracked, still treated as fire.
Or, on fifth day of Yangming, macules fail to emerge fully, evil toxin does not enter Shaoyang but directly enters Taiyin. This is not skipping meridians, but injury by diet or medication error. Taiyin days 1-2: hypochondriac pain, dysentery, Left Guan wiry-soft, Right Guan wiry-long, Qi Kou surging, Chi large, severe thirst, dry lips, dry tongue, clear spirit, thick yellow tongue coating, black-gray. Day three: black root, yellow middle, white tip, red eyes green face, Left Guan rapid, Right Guan slippery-large-forceful, Lung pulse large, both Chi blocked. Macules on head/face/chest/back, none on neck/abdomen. Yang qi unable to vent, Yin qi condensed. Taiyin day four: Left three positions blocked, Right Guan soft, Lung pulse large, Chi surging, severe thirst, red eyes red face, green nose, black lips indicate death, sunken macules. Taiyin day five: Cun/Guan all floating, Right Guan knotted, Left Guan tight, chills, headache, red eyes, green nose, green tongue, purple lips indicate death. Macule toxin attacks Liver, not transmitting to Jueyin, but evil strikes Jueyin.
Taiyin pulse favors weakness. Evil enters Spleen, qi abundant blood hot, flows to limbs, distributes to bones, penetrates Heart. Heart Spirit loses exclusive control, thus Ministerial Fire pathogen becomes fierce. Heart Spirit and Ministerial Fire lose position, body has no master. Hence, pain in limbs/bones, abdominal fullness, dry mouth, yellow/black tongue, dry lips. Five Zang and Six Fu including Large/Small Intestine, Bladder, Sanjiao are controlled. Fine-small pulse: Stomach qi uninjured. Slippery-large pulse: Stomach qi damaged. Stomach governs receiving grain, Spleen governs digesting grain; Stomach governs reception, Spleen governs transformation/moistening. Stomach reception depends on Lung, Spleen transformation depends on Liver. Upper part becomes phlegm, lower part becomes dregs. Diaphragm qi excess leads to phlegm stagnation in Danzhong. Heart qi heat leads to dreg stagnation in Small Intestine. Thirst for cold drinks indicates diaphragm heat. Drinking water without urination indicates scorched Lung lobes. Lung qi excess blocks Large Intestine pathway. Evil in Yin division unfavorable to see Yang pulse; disease in Yang division unfavorable to see Yin pulse. Taiyin disease favors fine-small-empty-soft, unfavorable to surging-large-slippery-excessive. Unblock meridians, guide blockages, prevent Wind-Wood from becoming evil, causing nine orifices blockage and death. Taiyin pulse not only seen at Right Guan; Left Cun, Left Guan, Right Chi also visible. Lung resides under Canopy, Lung qi stagnant, favors fine-small, unfavorable to solid-large. Similar to typical Shanghan transmitting to Taiyin: large pulse disease advances, small pulse retreats; forceful advances, weak retreats; slippery-excessive advances, empty-soft retreats; tight-excessive advances, knotted-soft retreats; surging-rapid advances, fine-soft retreats.
External manifestations: red eyes/face/tongue/lips, shaking hands/feet, restlessness, scorched-black coating. Toxin/pathogen fierce, pulse fine-small. Presence of Stomach qi means not untreatable. Green eyes/face/lips, white tongue, minute-fine pulse. Toxin sinks, sweat will occur leading to death. Taiyin disease: red face/eyes, purple lips/black tongue, rapid pulse at both Guan critical, choppy pulse fatal. White face red eyes, green nose/lips, gray coating, tight pulse at Left Chi/Right Guan fatal. Red eyes yellow face, nasal flaring green lips, rapid Right Cun, wiry Guan, absent both Chi fatal. Normal spirit, slightly black coating,革 pulse at both Guan fatal. Yellow tongue green eyes, white face/lips, weak pulse, cold extremities, white macules fatal. Mirror-like smooth tongue, red eyes green face, surging-large both Guan, surging-rapid both Chi, absent both Cun. Toxin sinks Lower Jiao, neck macules not emerging fatal. Thorny tongue, gray-black coating, abdominal/chest distension, severe thirst not desiring drink. Extreme Right Cun, soft Right Guan,涩 Left Guan. Chest binding fatal. Flat tip, hypochondriac pain, scorched-black coating, passing clear water, thirst not desiring drink. Knotted Left Chi, intermittent Left Cun, firm Right Guan. Heat binding Small Intestine fatal.
Yellow-white coating, mottled red-purple, green lips, white face, red eyes, soft Left Guan,涩 Right Guan, absent Lung pulse fatal. Thick white coating, upper gray-black, dry Spleen area, red lips, red eyes, white face, absent both Chi, soft Left Guan, deep-solid Right Guan, absent both Cun. White macules on neck fatal. Red-purple coating, red eyes yellow face, dry lips chest full, dull spirit, cold extremities, absent Right Guan, wiry-tight Left Guan, empty-large Left Chi. Macule toxin sinking fatal. Scorched-round-thick tongue, dry Huachi, scorched lips black teeth, red eyes red face, confused spirit, fine-small pulse, frequent calling, unconsciousness fatal. Consciousness retained may survive. Frequent stool, unconsciousness fatal. Frequent stool, gradually conscious may survive. Tongue does not return to normal gate, shivering fatal. After stool, tongue not moistening fatal untreatable. After stool, spirit suddenly clear, tongue moist but sweating fatal. After stool, wild-large pulse, blood from mouth/nose inevitable. Urgently take Gengyi San to cool Liver, store blood may survive. Delayed, vomiting blood fatal. Disease reaching Taiyin, many death signs; transmitting to Shaoyin, evil excess righteous deficiency, nineteen percent critical, many deaths; transmitting to Jueyin, Wind-Wood becomes evil, nine orifices closing, no need for detailed discussion. (This chapter discusses aspects overlapping with Warm Diseases, Mr. Zhou also stated it is not typical Shanghan disease.)
Any red tongue red face, with Yin pulses at both hands, or pulse swaying rootless, vague unreliable. Purple blisters like soybeans at Liver/Gallbladder areas on tongue. Heat toxin returning to Zang organs, untreatable. Left side severe, right side mild, middle not in Liver/Gallbladder area lighter. Examine pulse, if salvageable, must save. (Old saying: tongue edge missing like saw teeth indicates death, which is this meaning.)
