After sweating therapy, if the disease remains unresolved, with chills and fever persisting as before, it may be due to incomplete elimination of exterior pathogens, transmission of pathogens into the interior, or pathogens invading internally by taking advantage of deficiency. Treatment should be administered according to the specific syndrome.
[Sweating Therapy] If Mahuang Tang (Ephedra Decoction) or Guizhi Tang (Cinnamon Twig Decoction) have been taken previously, and the pulse is surging (Hongda), with symptoms resembling malaria, re-administering sweating therapy will likely resolve the condition; use Mahuang Tang (Ephedra Decoction).
[Simultaneous Resolution of Exterior and Interior] If fever and sweating do not resolve the condition, accompanied by epigastric fullness and hardness, vomiting, and diarrhea, use Dachaihu Tang (Major Bupleurum Decoction).
[Clearing Heat] If excessive sweating occurs after taking Guizhi Tang (Cinnamon Twig Decoction), leading to extreme thirst, unrelenting irritability, and a surging pulse, use Baihu Jia Renshen Tang (White Tiger Decoction with Ginseng).
[Purgation] After sweating, if there is no aversion to cold but only aversion to heat, or if there is steaming fever, this indicates excess; use Tiaowei Chengqi Tang (Regulate the Stomach and Order the Qi Decoction). After sweating, Guizhi Tang (Cinnamon Twig Decoction) should not be used again; if sweating and wheezing occur without significant surface heat, use Mahuang Xingren Shigao Gancao Tang (Ephedra, Apricot Kernel, Gypsum and Licorice Decoction).
[Separating and Draining] After sweating therapy for Taiyang disease (Disease of the Bladder Channel), excessive sweating dries the stomach, causing insomnia. If the patient desires water, give it in small amounts frequently until the stomach qi harmonizes and recovery ensues. If the pulse is floating, urination is difficult, with slight fever and thirst characteristic of Xiao Ke (Wasting-Thirst), use Wuling San (Five-Ingredient Powder with Poria). After sweating, if the pulse is surging and rapid with irritability and thirst, use Wuling San (Five-Ingredient Powder with Poria).
[Harmonizing the Middle] If abdominal fullness occurs after sweating, use Noupiao Shengjiang Banxia Gancao Renshen Tang (Pinellia, Ginger, Licorice and Ginseng Decoction with Magnolia Bark). If excessive sweating causes palpitations at the heart region, with a desire to tremble/shiver, use Guizhi Gancao Tang (Cinnamon Twig and Licorice Decoction).
[Warming the Channels] If the disease remains unresolved after sweating but aversion to cold worsens, indicating exterior deficiency, use Shaoyao Gancao Fuzi Tang (Peony, Licorice and Aconite Decoction); this is suitable only when the pulse is fine and the body feels fatigued. If Taiyang disease sweating leads to unresolved condition with persistent fever, palpitations, body tremors, and a sensation of shaking as if falling to the ground, use Zhenwu Tang (True Warrior Decoction). If body pain persists after sweating with a deep pulse, use Guizhi Jia Shaoyao Renshen Tang (Cinnamon Twig Decoction with Added Peony and Ginseng). If Taiyang disease sweating causes continuous leakage of sweat, aversion to wind, difficulty in urination, and spasm/stiffness of the four limbs making flexion and extension difficult, use Guizhi Jia Fuzi Tang (Cinnamon Twig Decoction with Added Aconite). If excessive sweating leaves heat unabated, with internal spasms, limb pain, diarrhea, and aversion to cold, use Sini Tang (Four Reversal Decoction). If after sweating there is palpitation below the umbilicus with a tendency toward Ben Tun (Running Piglet), use Fuling Guizhi Gancao Dazao Tang (Poria, Cinnamon Twig, Licorice and Jujube Decoction).
If body heat persists, diarrhea continues, chest and abdomen are full, and there is thirst and irritability: The *Huo Ren* book states that eliminating pathogenic factors in Shang Han (Cold Damage) relies on only three methods: sweating, vomiting, and purgation. If these three methods are applied appropriately, the disease trend will easily decline and heal. However, if these methods are misapplied, especially when the disease is critical and severe, the transmission and transformation will not cease, which is indeed worrying. Moreover, after sweating, vomiting, or purgation, if pathogens invade due to deficiency and remain unresolved, or if obstruction persists, one must assess the deficiency and excess to treat accordingly. Ancients stated that understanding the deficiency and excess of pathogens, knowing when sweating, vomiting, and purgation fail, and appropriately applying warming tonification and acupuncture can achieve perfect therapeutic results.
[Vomiting Therapy] In Shang Han (Cold Damage) lasting five to six days, after severe purgation, if body heat persists and there is painful knotting in the heart region indicating the condition is not yet resolved, use Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction). If after purgation there is irritability, abdominal fullness, and restlessness lying down or sitting up, use Zhizi Houpo Tang (Gardenia and Magnolia Bark Decoction).
[Clearing Heat] In Taiyang disease presenting with Guizhi Tang (Cinnamon Twig Decoction) syndrome, if the physician incorrectly uses purgation, leading to unceasing diarrhea and a hurried pulse indicating the exterior is not resolved; if accompanied by wheezing and sweating, use Gegen Huanglian Huangqin Tang (Kudzu, Coptis and Scutellaria Decoction).
[Purgation] In Yangming disease, after purgation, if there is mental distress and irritability (Ao Nan), use Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction). If there are dry feces, use Da Chengqi Tang (Major Order the Qi Decoction).
[Warming] After Taiyang disease purgation, if the pulse is hurried and there is chest fullness, use Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction without Peony). If there is slight aversion to cold, remove Peony and add Aconite. If treated erroneously with pill-based purgatives, resulting in persistent body heat and slight irritability, use Zhizi Ganjiang Tang (Gardenia and Dried Ginger Decoction).
[Resolving Erroneous/Displaced Pathogens] After seven days, following severe purgation, if the cun pulse is deep and slow, hands and feet are cold, there is diarrhea, the pulse is imperceptible, throat discomfort occurs, and pus and blood are expectorated; if diarrhea is unceasing, it is difficult to treat; use Mahuang Shengma Tang (Ephedra and Cyptotricha Decoction).
