伤寒发热、无汗、呕吐、不能进食，却反而出现汗出连绵不断的情况，这是病邪转属阳明经的表现。
太阳伤寒的经证尚未解除，表现为发热、无汗、呕吐、不能进食，这是因为寒邪束缚逼迫，导致胃气壅滞上逆，所以无汗且呕吐，食物无法下行。如果反而出现汗出连绵不断，这必定是因为胃腑有热，蒸腾熏灼皮毛所致，这就是病邪转属阳明经。
伤寒脉象浮而缓，手足自然温暖，这是病势关联在太阴脾经。太阴病应当出现身体发黄的症状；如果小便通畅自利，则不会发黄。到了七八天，大便变硬，这就属于阳明病了。伤寒病转系于阳明经的患者，其人会表现为微微汗出连绵不断的样子。
太阳伤寒若阳气旺盛，则传变为阳明病；若阴气旺盛，则传变为太阴病。如果脉象浮而缓，手足自温，这是阳明和太阴两经都有的共同征象，且以关联太阴为主。然而太阴病应当身体发黄，这是因为湿土之气被郁遏，必然显现黄色。虽然脾胃二脏都有发黄的证候，但胃的发黄是由太阴湿土之邪传变而来的。如果小便自利，湿气得以排出，就不能发黄。那么太阴病和阳明病如何区分呢？必须通过观察大便来判断：太阴病的大便自利（稀溏），阳明病的大便则坚硬。到了七八天大便变硬的，这就是阳明病。另外，太阴病通常无汗，当伤寒转系阳明时，患者会出现微微汗出连绵不断的情况。（这与太阴病至七八日突然烦躁并下利的条文是互文见义的关系）
问：疾病中有太阳阳明、正阳阳明、少阳阳明，这是什么意思？答：太阳阳明，是指脾约证；正阳阳明，是指胃家实证；少阳阳明，是指经过发汗或利小便治疗后，胃中干燥、烦热、大便困难的情况。
阳明病有的从太阳经传来，有的从少阳经传来，也有由本经直接入里的。从太阳经传来的称为太阳阳明。太阳阳明，表现为小便频数而大便困难，这是因为膀胱津液枯竭，脾胃失去滋润，导致脾气约束结聚，粪便颗粒坚小。由本经直接入里的称为正阳阳明。正阳阳明，是指胃腑阳气实盛，不需要等待其他经的病邪传入，一旦有表邪外束，腑内热气就会自发产生。从少阳经传来的称为少阳阳明。少阳阳明，是指经过发汗或利水治疗后，胆液枯槁，导致胃中燥热，大便艰难。太阳阳明是由于寒水之气的枯竭所致；少阳阳明是由于相火之气的旺盛所致；正阳阳明是由于燥金之气的盛大所致。
Taiyang cold damage (Taiyang Cold Damage) with fever, absence of sweating, vomiting, and inability to eat, yet conversely presenting with continuous sweating, indicates a transmission to the Yangming stage.
The exterior syndrome of Taiyang cold damage has not yet resolved, manifesting as fever, absence of sweating, vomiting, and inability to eat. This is due to cold pathogenic factors constraining and forcing the stomach qi to become stagnant and rebellious, resulting in absence of sweating and vomiting, preventing food from descending. If conversely there is continuous sweating, it must be because heat in the Yangming fu-organ steams and薰zes the skin and hair; this constitutes a transmission to Yangming.
In cold damage, if the pulse is floating and slow, and the hands and feet are naturally warm, the disease is associated with the Taiyin stage. In Taiyin diseases, the body should turn yellow; however, if urination is free and easy, jaundice will not occur. After seven or eight days, if the stool becomes hard, it is classified as a Yangming disease. When cold damage transmits to the Yangming stage, the patient presents with slight, continuous sweating (Hanhan).
In Taiyang cold damage, if yang qi is vigorous, the disease transmits to Yangming; if yin qi is vigorous, it transmits to Taiyin. A floating and slow pulse with naturally warm hands and feet are common signs of both Yangming and Taiyin, but here it associates with Taiyin. However, Taiyin diseases typically present with jaundice because damp-earth is constrained, inevitably showing yellow coloration. Although both spleen and stomach can exhibit jaundice, the jaundice of the stomach is transmitted from Taiyin damp-earth. If urination is free and easy, dampness is eliminated, and jaundice cannot develop. How then to distinguish between Taiyin and Yangming? One must examine the stool: Taiyin stools are loose (Li), while Yangming stools are hard. After seven or eight days, if the stool is hard, this is a Yangming disease. Furthermore, Taiyin typically has no sweat; when cold damage transmits to Yangming, the patient exhibits slight, continuous sweating (this passage mutually illuminates the clause regarding Taiyin sudden irritability and diarrhea after seven or eight days).
Question: There are Taiyang-Yangming, Zhengyang-Yangming, and Shaoyang-Yangming in diseases. What does this mean? Answer: Taiyang-Yangming refers to Pi Yue (Spleen Constraint); Zhengyang-Yangming refers to Wei Jia Shi (Stomach Fullness/Excess); Shaoyang-Yangming refers to dryness, irritability, and heat in the stomach with difficult defecation following diaphoresis or promotion of urination.
Yangming diseases may transmit from Taiyang, from Shaoyang, or arise directly from the meridian itself. Those coming from Taiyang are called Taiyang-Yangming. Taiyang-Yangming manifests as frequent urination and difficult defecation, caused by the depletion of bladder fluids leading to loss of moistening in the spleen and stomach, causing spleen qi to constrain and form small, hard fecal pellets. Those arising directly from the meridian are called Zhengyang-Yangming. Zhengyang-Yangming is characterized by excess yang in the stomach-fu, which does not require transmission from other meridians; once external exterior pathogens constrain, internal fu-heat spontaneously arises. Those coming from Shaoyang are called Shaoyang-Yangming. Shaoyang-Yangming results from the exhaustion of gallbladder fluids following diaphoresis or water-draining therapies, leading to dryness and heat in the stomach and difficult defecation. Taiyang-Yangming stems from the depletion of Cold-Water; Shaoyang-Yangming stems from the exuberance of Ministerial Fire; Zhengyang-Yangming stems from the predominance of Dry-Metal.
