张仲景说：出现下利（腹泻），肛门疼痛，应当用温法治疗。可以用炒热的盐末熨烫患处。另一方法是用炙过的枳实熨烫。《千金翼方》说：适宜用炙过的枳实。如果用炒盐等，像炒蚕沙之类的都可以用来熨烫。庞安时先生说：将枳实末与盐混合使用，效果更好。如果单独使用枳实末则不恰当。枳实必须逐片炙烤后使用，也就是枳壳。
庞安时先生说：脐中冷结，不可以立即熨烫。冷气攻冲心腹，必然致死。必须先用药温补，久待之后才可以熨烫。
又说：脐下冷结，或者阳气闭阻不通的，大小便不通畅。虽然服用很多药物，不见效果。用炒盐熨烫脐下，片刻之后即可通畅。如果病人已经服用了巴豆、甘遂、大黄、轻粉等药过多的，稍微通畅后即会导致严重腹泻而损伤人体。应当仔细审察。
庞安时说：伤寒病，医生将火放在床下，或者周身用火逼迫劫取汗液，或者熨烫，或者误用灸法，这些都是火邪所致。张仲景说：伤寒脉浮，医生用火逼迫劫汗，导致亡阳（阳气脱失），必定出现惊狂，或者卧起不安的症状，适宜用桂枝去芍药加蜀漆牡蛎龙骨救逆汤。
又说：因火逆误下，又因烧针导致烦躁的，以桂枝甘草汤主治。郭雍说：可以代替救逆汤使用它。
庞安时说：灸及烧针后，证候类似火劫的，都适宜用火劫法治疗。出现烦躁、惊悸及狂乱，使用《金匮要略》中的风引汤尤其良好。柴胡加龙骨牡蛎汤也通用。
《千金方》说：其病形不适合灸治，因为火成为邪气，散走血脉。损伤脉络还可以，损伤脏腑则病情严重。井穴和俞穴周围红肿，黄汗自出，经络外部溃烂，肌肉腐烂化为痈脓。这称为火疸，是医生治疗所伤。郭雍说：《千金翼方》中有火疸这一证候，错简在狐惑篇之后。又将微数之脉不可灸的证候合并为一处。又说：应用泻心汤。这些言论错误谬误，不可继续引用。微数之脉不可灸，已经在本书门中见到。单独留下火疸这一证候，似乎属于火邪，所以记录在这里。《外台秘要》用泻心汤治疗蚀于上部属于狐惑，也将火疸和微数脉放在后面。这种错误由来已久。
Zhang Zhongjing said: When diarrhea occurs with pain in the anal canal, a warming method should be applied. One may use hot salt powder for moxibustion-like熨烫 (hot compress). Another method is to use roasted Zhi Shi (Immature Bitter Orange) for hot compress. *Qianjin Yi Fang* states that roasted Zhi Shi is suitable. If using roasted salt or similar materials like roasted Bombyx Batryticatus (Can Sha), they can also be used for hot compress. Pang Anshi stated that mixing Zhi Shi powder with salt yields better results. Using Zhi Shi powder alone is inappropriate. Zhi Shi must be roasted slice by slice; this refers to Zhi Qiao (Aurantium Fructus).
Pang Anshi stated: Cold accumulation in the umbilicus cannot be immediately treated with hot compress. If cold qi attacks the heart and abdomen, death is inevitable. One must first warm it with medicine, and after a long period, apply hot compress.
He also said: For cold accumulation below the umbilicus, or where Yang Qi is blocked leading to obstruction of urination and defecation, although many medicines are taken without effect, applying hot compress with roasted salt to the area below the umbilicus will lead to unblocking within moments. If the patient has already taken excessive amounts of Ba Dou (Crotonis Fructus), Gan Sui (Kansui Radix), Da Huang (Rhei Radix et Rhizoma), or Qing Fen (Calomelas), slight unblocking will result in severe diarrhea and damage the body. Careful examination is required.
Pang Anshi said: In Shanghan (Cold Damage), if the doctor places fire under the bed, uses fire around the whole body to force sweating, applies hot compress, or mistakenly uses moxibustion, these are all caused by Fire Evil. Zhang Zhongjing said: In Shanghan with a floating pulse, if the doctor uses fire to force sweating, causing Wang Yang (Loss of Yang Qi), there will inevitably be panic and madness, or restlessness in lying down and rising up. Gui Zhi Qu Shao Yao Jia Shu Xi Mu Li Long Gu Jiu Ni Tang (Cinnamon Twig Decoction minus Peony plus Chinese Asparagus Root, Oyster Shell, and Dragon Bone to Rescue from Deviation) is indicated.
He also said: For fire deviation followed by purgation, resulting in irritability due to burning needles, Gui Zhi Gan Cao Tang (Cinnamon Twig and Licorice Decoction) is the primary treatment. Guo Yong stated that it can be used as a substitute for Jiu Ni Tang.
Pang Anshi said: After moxibustion and burning needles, if symptoms resemble those of fire coercion, they should all be treated with fire coercion methods. For irritability, palpitations, and madness, Feng Yin Tang (Wind-Driving Decoction) from *Jin Gui Yao Lue* is particularly excellent. Chai Hu Jia Long Gu Mu Li Tang (Bupleurum Decoction plus Dragon Bone and Oyster Shell) is also generally applicable.
*Qian Jin Fang* states: The condition is not suitable for moxibustion because fire becomes evil, dispersing through the blood vessels. Injury to the vessels is tolerable, but injury to the zang organs is severe. Swelling at the Jing-Well and Shu-Acupoints, spontaneous yellow sweat, external rotting of meridians, and muscle corruption turning into abscesses and pus constitute Huo Dan (Fire Jaundice), which is iatrogenic injury. Guo Yong stated: *Qian Jin Yi Fang* contains a chapter on Huo Dan, which was misplaced after the Hu Huo (Fox-Sore) chapter. It also combined the contraindication of moxibustion for fine-rapid pulses into one section. It further stated that Xie Xin Tang (Drain the Epigastrium Decoction) should be used. These statements are erroneous and unreliable. The contraindication of moxibustion for fine-rapid pulses has already been seen in this chapter. Only leaving the Huo Dan syndrome seems related to Fire Evil, so it is recorded here. *Wai Tai Mi Yao* uses Xie Xin Tang to treat erosion in the upper part belonging to Hu Huo, placing Huo Dan and fine-rapid pulse afterwards. This error has existed for a long time.
