伤寒脉浮，医以火逼劫之，亡阳，必惊狂，起卧不安者，桂枝去芍药加蜀漆龙骨牡蛎救逆汤主之。
少阴病，出现呕吐和腹泻，手脚冰冷，烦躁不安到快要死去的样子，应当用吴茱萸汤主治。
伤寒病，脉象浮，自汗出，小便频数，心烦，轻微怕冷，脚部抽筋拘急，反而给予桂枝汤，想要攻解表邪，这是误治。导致病情变化后出现四肢厥冷，咽喉干燥，烦躁，呕吐逆气，应给予甘草干姜汤，以恢复其阳气；如果四肢厥冷痊愈、脚部变温暖了，再给予芍药甘草汤，脚部就能伸直；如果出现胃气不和，说胡话（谵语），少量给予调胃承气汤；如果是重发汗，又加上烧针治疗的，应当用四逆汤主治。
问：证候表现像阳旦证（即桂枝汤证），按照常规法治疗却加重，出现四肢厥冷，咽喉干燥，两小腿拘挛急促且说胡话。老师说：半夜时手脚应当变暖，双脚应当伸直。后来果然如老师所说。为什么能预知这一点？回答说：寸口脉浮而大，浮表示有风邪，大表示正气虚弱，风邪则产生微热，正气虚弱则两小腿拘挛。病状形象类似桂枝汤证，因此在方中加附子参入其中，增加桂枝令其出汗，附子温通经脉，这是因为亡阳的缘故。出现四肢厥冷，咽喉干燥，烦躁，阳明腑实内结，说胡话烦乱，再饮用甘草干姜汤，夜半阳气回复，两脚应当发热，小腿尚且轻微拘挛急促，再次给予芍药甘草汤，然后小腿才能伸直，再用承气汤使大便微溏，从而停止说胡话，所以知道病可以痊愈。
伤寒病六七天，经过大力攻下之后，寸脉沉而迟，手脚厥冷，下部（尺）脉摸不到，咽喉不利，唾吐脓血，泄泻不止的，属于难治之症，用麻黄升麻汤主治。
伤寒病八九天，经过攻下治疗后，胸中胀满，心烦惊悸，小便不利，说胡话，全身沉重，不能翻身转侧的，用柴胡加龙骨牡蛎汤主治。
脉象微细而数，千万不可用灸法，因为火邪成为致病因素，会导致烦闷逆乱，这属于追虚逐实（对虚处更虚，实处更实）；血液散乱于脉中，火气虽然微弱，但内攻的力量很强，会焦枯骨骼损伤筋脉，血液难以恢复。
脉浮适宜用发汗法解除表邪，如果用火灸治疗，邪气无从排出，反而因火邪而亢盛，疾病从腰部以下必定沉重且麻木不仁，这叫作火逆。
伤寒病脉浮，医生用火法逼迫劫夺津液，导致亡阳，必定出现惊恐狂乱，坐卧不安的，用桂枝去芍药加蜀漆龙骨牡蛎救逆汤主治。
Shaoyin disease, characterized by vomiting and diarrhea, cold extremities, and severe restlessness bordering on death, is primarily treated with Wuzhuyu Tang (Evodia Decoction).
In Shanghan (Cold Damage) disease, if the pulse is floating, there is spontaneous sweating, frequent urination, mental restlessness, slight aversion to cold, and cramping of the feet, administering Guizhi Tang (Cinnamon Twig Decoction) to attack the exterior is an error. This mistake leads to jue (cold extremities), dryness in the throat, restlessness, and vomiting. In such cases, Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction) should be given to restore yang qi. If the jue resolves and the feet become warm, Shaoyao Gancao Tang (Peony and Licorice Decoction) should then be administered, which will allow the legs to extend. If there is stomach disharmony manifesting as delirium (chan yu), a small amount of Tiaowei Chengqi Tang (Regulate the Stomach and Purge Downward Decoction) should be given. If excessive sweating was previously induced and moxibustion or burning needles were added, Sini Tang (Frigid Extremities Decoction) is indicated.
Question: The syndrome resembles Yangdan Syndrome (Guizhi Tang pattern), yet treatment according to standard methods exacerbates the condition, leading to cold extremities, dry throat, bilateral calf spasms, and delirium. The Master stated: "By midnight, the hands and feet will become warm, and the feet will extend." Later, this prediction came true. How was this known? Answer: The cunkou (radial artery at the wrist) pulse is floating and large. Floating indicates wind; large indicates deficiency. Wind generates slight heat; deficiency causes calf spasms. The clinical presentation resembles the Guizhi Tang pattern, so Fuzizi (Aconiti Lateralis Radix Preparata) was added to the formula, and Guizhi (Cinnamon Twig) was increased to induce sweating. Fuzizi warms the meridians because of yang collapse. With cold extremities, dry throat, restlessness, Yangming internal binding, and delirious confusion, Gancao Ganjiang Tang is administered again. By midnight, yang qi returns, and the feet become warm. Since the calves are still slightly spasmodic, Shaoyao Gancao Tang is given again, allowing the calves to extend. Using Chengqi Tang to produce slight loose stools stops the delirium. Thus, it is known that the disease can be cured.
After six or seven days of Shanghan disease, following vigorous purgation, if the cun pulse is deep and slow, extremities are cold, the lower pulses (chi position) are imperceptible, the throat is obstructed, pus and blood are expectorated, and diarrhea persists uncontrollably, this is difficult to treat. Mahuang Shengma Tang (Ephedra and Ma Huang Shen Decoction) is indicated.
After eight or nine days of Shanghan disease, following purgation, if there is chest fullness, mental irritability and fright, difficulty in urination, delirium, heaviness of the entire body, and inability to turn over, Chaihu Jia Longgu Muli Tang (Bupleurum Plus Dragon Bone and Oyster Shell Decoction) is indicated.
A pulse that is fine and rapid must not be treated with moxibustion. Fire becomes a pathogenic factor, causing vexation and rebellion, exacerbating deficiency and excess. Blood scatters within the vessels; although fire energy is subtle, its internal attacking power is strong, scorching bones and damaging sinews, making blood recovery difficult.
When the pulse is floating, resolution via sweating is appropriate. If moxibustion is used instead, the pathogen has no outlet and flourishes due to fire. The disease manifests as heaviness and numbness from the waist downward, termed Huoni (Fire Reversal).
In Shanghan disease with a floating pulse, if a physician uses fire methods to force and deplete fluids, causing yang collapse, it inevitably leads to fright, mania, and restlessness with inability to sit or lie comfortably. Guizhi Qu Shaoyao Jia Shuqi Longgu Muli Jiuni Tang (Cinnamon Twig Decoction Without Peony Plus Chinese Asarum, Dragon Bone, and Oyster Shell for Rescue from Reversal) is indicated.
