阳明经由燥金主令，足阳明胃经属戊土，其气化受燥金影响。若太阴脾湿过胜，则阳明之气化为湿；若阳明燥气过胜，则太阴之气化为燥，因此阳明经脉容易遭受燥邪致病。冬季肾水失于封藏，相火上升，导致胃中津液枯竭，脾之精微亦随之耗亡。太阴的湿气久留会转化为阳明的燥气，春夏季节感受病邪时，卫阳被遏制闭郁，营分热邪郁结而发，致使脾胃焦枯、肺金燔灼，燥气更加旺盛。阳明经脉挟持鼻部、联络眼部，循行于身体前面，所以出现眼睛疼痛、鼻子干燥以及身体发热无法安卧的症状。阳气没有比阳明更盛的，若燥热在经脉中不得宣泄发散，拖延时日会导致胃腑积热，脏阴逐渐干枯，埋下日后危机的隐患。在腑热尚未发动之时，采用清凉泄热的方法疏通经络以清除热邪，就能杜绝后患。使用素雪丹主治。
素雪丹：治疗阳明经身热、眼痛、鼻干、无法安卧、胸中烦闷、口渴。

瘟疫病邪传变至阳明经，腑热尚未发作，治法宜清热兼以解表。热势严重者，必然损伤肺气，应当使用人参白虎汤清泻肺金之热，益气生津，这才是妙法。（人参白虎汤见前文。）
三阳经中，阳明经最为强盛。足阳明胃经从燥金化气，若太阳表邪未解，经热内传，因火性就燥，必入阳明。此时阴气盛于体内，阳气盛于体表，腑燥尚未形成，但经燥先动，胆木之气逆行克制胃土，导致胃气壅滞遏阻，不能容纳受纳，所以出现呕吐和泄利。这是因为经邪郁迫导致腑气不畅的缘故。

病邪传入阳明经，若不能通过发汗解除，对于腑阳素来旺盛的人，由于经热郁蒸，导致腑热内生。腠理开泄，可见大汗淋漓，但汗出越多，脾胃越焦枯，燥气越增加，热势越盛。常在申时与酉时之间（下午3-7点），按时发热，如潮汐般准时，称为潮热。燥土消烁心液，所以出现胡言乱语（谵语）。燥屎壅滞阻碍腑气，所以腹部胀满疼痛。拖延时日会导致脏阴耗竭，营气郁陷，关乎生死，不可不紧急攻下。使用大小承气汤泄下，并加入养阴凉血的药物，使脏阴逐渐恢复，营郁得以外达。

Eye Pain and Dry Nose
The Yangming channel is governed by the dryness of Metal. The Foot-Yangming Stomach Channel belongs to Wu Earth, and its Qi transformation is influenced by Dryness Metal. If Taiyin Spleen Dampness prevails, Yangming Qi transforms into Dampness; if Yangming Dryness prevails, Taiyin Qi transforms into Dryness. Therefore, the Yangming channels are prone to diseases caused by Dryness. When Winter Water fails to store properly, Ministerial Fire ascends, causing stomach fluids to wither and spleen essence to perish. Long-standing Taiyin Dampness transforms into Yangming Dryness. In spring and summer, when pathogenic factors are contracted, defensive Yang is obstructed and closed, while nutritive heat stagnates and erupts, leading to the scorching of Earth (Spleen/Stomach) and the burning of Metal (Lung), thereby intensifying Dryness. The Yangming channel connects with the nose and eyes and runs along the anterior aspect of the body; thus, symptoms include eye pain, dry nose, fever, and inability to lie down. Among all Yang channels, Yangming is the most vigorous. If Dryness-Heat remains in the channels without venting or dispersing, it will eventually lead to accumulated heat in the stomach fu organ and gradual depletion of zang yin, posing a latent crisis for the future. At the stage before fu heat arises, cooling and purging methods should be used to unblock the channels and clear heat, thereby preventing subsequent complications. Su Xue Dan is indicated.
Su Xue Dan: Treats Yangming channel syndrome characterized by body heat, eye pain, dry nose, insomnia, chest irritability, and thirst.
Ingredients: Floating Duckweed (Sanqian), Gypsum (Sanqian, crushed), Ophiopogon Tuber (Erqian, heart removed), Scrophularia Root (Erqian), Kudzu Root (Erqian), Moutan Bark (Erqian, wine-washed), White Peony Root (Yiqian), Fresh Ginger (Sanqian), Licorice Root (Yiqian).
Preparation and Administration: Decoct three cups of water with a pinch of Coix Seed until half a cup remains, strain, and take hot. Cover with clothing to induce slight sweating. For vomiting, add Processed Pinellia Tuber (Erqian).
When epidemic disease pathogens transmit to the Yangming channel and fu heat has not yet arisen, the treatment principle is to clear heat and release the exterior. If heat is severe, lung qi is inevitably damaged; Ren Shen Bai Hu Tang (Ginseng and White Tiger Decoction) should be used to clear Lung Metal heat, replenish qi, and generate fluids, which is the optimal approach. (See Ren Shen Bai Hu Tang in previous sections.)
Eye Pain, Dry Nose, Vomiting, and Diarrhea
Among the Three Yang channels, Yangming is the strongest. The Foot-Yangming Stomach Channel transforms from Dryness Metal. If exterior pathogens from the Taiyang channel remain unresolved, channel heat transmits inward. Since fire tends toward dryness, it must enter Yangming. With Yin prevailing internally and Yang prevailing externally, fu dryness has not yet formed, but channel dryness moves first. Gallbladder Wood reverses its flow and attacks Stomach Earth, causing Qi stagnation and obstruction in the Stomach, which cannot accept or digest food. Thus, vomiting and diarrhea occur due to the oppression of fu Qi by channel pathogens.

Preparation and Administration: Decoct in water until half a cup remains, strain, and take hot.
Yangming Fu Syndrome: Sweating, Tide-like Fever, Delirium, Abdominal Fullness, and Constipation
If pathogens transmit to the Yangming channel and cannot be resolved through sweating, in individuals with inherently strong Fu Yang, channel heat stagnation and steaming leads to internal fu heat generation. When pores open, profuse sweating occurs. However, the more sweat is lost, the drier the Earth becomes; the more dryness increases, the stronger the heat grows. Fever often occurs at the junction of Shen and You hours (3 PM–7 PM), regular as the tide, known as tide-like fever. Dry Earth consumes Heart fluids, causing delirium. Dry fecal matter obstructs fu Qi, causing abdominal fullness and pain. Delay leads to the exhaustion of zang yin and depression of Ying Qi, a critical juncture for life and death requiring urgent purgation. Use Da Cheng Qi Tang or Xiao Cheng Qi Tang for purgation, adding herbs that nourish Yin and cool blood to restore zang yin and allow depressed Ying Qi to reach the exterior.
