发汗之后，脉象浮数，出现心烦、口渴症状的，用五苓散主治（方剂在太阳病第四十一节）。
发汗之后，热随汗液发散，于是脉象呈现浮数，证候表现为心烦口渴，这是汗出导致阳气虚弱、脾土湿气停滞而相火上炎。大概是因为火气郁闭、阳气潜藏完全依赖脾土之阳；若脾阳亡失、湿气妄动，肺胃之气不降，君火上炎，所以脉证如此。适宜用五苓散燥湿健脾、泄除水湿。如果尚未发汗却出现浮数、烦渴的脉证，则适宜用大青龙汤，而不适宜用五苓散了。
伤寒病，脉象浮，自汗出，小便频数，心中烦躁，轻微恶寒，脚部拘挛急迫，反而给予桂枝汤想要攻解表邪，这是误治。得此误治后，立即出现四肢厥冷、咽喉干燥、躁扰不安、呕吐逆气等症状，应当制作甘草干姜汤给予服用，以恢复其阳气。如果四肢厥冷痊愈、足部转温，再制作芍药甘草汤给予服用，其脚部自然伸展。如果胃气不和出现谵语，少量给予调胃承气汤。如果再次发汗，又加上烧针疗法，则以四逆汤主治（方剂在太阴病第三节）。
脉浮、自汗出，是里热向外发散的表现。小便频数，则大便必然坚硬。心中烦躁，是胃热熏蒸冲脉所致。阳明病虽然患病一日，恶寒症状将会自行停止，随即会出现自汗出且怕热的症状。轻微恶寒，说明表邪未完全解除；自汗虽出但未能立即发作（指大汗），这也是调胃承气汤的适应证（《阳明篇》上：太阳病，如果用吐法、下法或发汗法后出现轻微心烦，小便频数，大便因此变硬，与小承气汤调和即可痊愈；阳明病，未经过吐下法却心烦的，可给予调胃承气汤，即此证）。医生因为脉浮、自汗，将病象判断为太阳中风证，反而给予桂枝汤加附子，并增加桂枝用量以攻解表邪，这是大大的错误。得此误治后，汗出过多导致阳气亡失，致使手足厥冷、咽喉干燥，阳气脱离根本而产生烦躁，胃气上逆而作呕吐。此时制作甘草干姜汤给予服用，甘草培补脾土而补益中气，干姜温暖胃腑而降逆气，阳气回复、肢体温暖，因此四肢厥冷痊愈、足部转温。其脚部拘挛急迫的原因，是由于肝木枯燥而导致筋脉收缩。再制作芍药甘草汤给予服用，甘草舒缓筋脉而缓解急迫，芍药清泻风热而滋润燥邪，其脚部自然伸展。如果胃气不和、脾土干燥出现谵语，少量给予调胃承气汤，则胃气得以调和。桂枝发汗算是一次误逆，如果不使用姜、甘回阳反而再次发汗，或者又加上烧针以大量耗损阳气，这是第二次误逆，应当迅速使用四逆汤来回阳救逆。姜、甘加上附子，是水土双温的方法。
After sweating therapy, if the pulse is floating and rapid, accompanied by vexation and thirst, Wuling San (Five-Ingredient Powder with Poria) should be administered (Formula located in Taiyang Chapter 41).
After sweating therapy, heat dissipates with the sweat, resulting in a floating and rapid pulse, and symptoms of vexation and thirst. This indicates that sweating has led to Yang deficiency, dampness stagnation in the Spleen Earth, and the rising of ministerial fire. Generally, the confinement of fire and the hibernation of Yang rely entirely on the Yang of the Spleen Earth. If Spleen Yang is lost and dampness moves recklessly, the Qi of the Lung and Stomach fails to descend, and Sovereign Fire flares upward, thus presenting such pulse and symptom patterns. It is appropriate to use Wuling San to dry dampness and leach out water-dampness. However, if these floating, rapid, vexatious, and thirsty pulse and symptoms appear before any sweating therapy has been induced, Da Qing Long Tang (Major Green Dragon Decoction) should be used, rather than Wuling San.
In Shaoyin cold damage disease, with a floating pulse, spontaneous sweating, frequent urination, mental vexation, slight aversion to cold, and cramping/tightness of the legs, administering Guizhi Tang (Cinnamon Twig Decoction) to attack the exterior is an error. Following this error, the patient immediately develops cold limbs (Jue), dry throat, restlessness, vomiting, and rebellious Qi. One should prepare Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction) for them to restore their Yang. If the cold limbs resolve and the feet become warm, one should then prepare Shaoyao Gancao Tang (Peony and Licorice Decoction) for them, at which point the legs will extend naturally. If there is disharmony of Stomach Qi leading to delirious speech, administer a small amount of Tiaowei Chengqi Tang (Regulate the Stomach and Direct to Enter Decoction). If excessive sweating is induced again, or if burning needle therapy is added, Sini Tang (Frigid Extremities Decoction) should be administered (Formula located in Taiyin Chapter 3).
A floating pulse and spontaneous sweating indicate that interior heat is leaking outward. Frequent urination implies that the stool must be hard. Mental vexation is caused by the steaming of Stomach heat affecting the Chong Mai. Although Yangming disease presents for only one day, the aversion to cold will cease spontaneously, followed by spontaneous sweating and aversion to heat. Slight aversion to cold suggests that the exterior pathogen is not yet fully resolved; although sweating occurs, it does not immediately manifest as profuse sweating. This is also an indication for Tiaowei Chengqi Tang (As stated in the Yangming Chapter: In Taiyang disease, after emesis, purgation, or sweating, if mild vexation appears, frequent urination occurs, and the stool becomes hard due to this, Xiao Chengqi Tang can harmonize the condition and cure it; in Yangming disease, if vexation occurs without prior emesis or purgation, Tiaowei Chengqi Tang may be given, which corresponds to this case). The physician, observing the floating pulse and spontaneous sweating, misidentified the presentation as Taiyang Wind Strike syndrome, and erroneously administered Guizhi Tang plus Fuzi (Prepared Aconite Root), increasing the dosage of Guizhi to attack the exterior. This is a major error. Consequently, excessive sweating leads to Yang collapse, causing cold limbs and dry throat. Yang Qi detaches from its root, generating vexation, while Stomach Qi rebels, causing vomiting. At this stage, Gancao Ganjiang Tang should be prepared and administered. Gancao (Licorice Root) nourishes Earth and tonifies the Middle Jiao, while Ganjiang (Dried Ginger) warms the Stomach and directs rebellious Qi downward. As Yang returns and the limbs warm, the cold limbs resolve and the feet become warm. The cramping of the legs is due to dryness of Liver Wood causing tendon contraction. One should then prepare Shaoyao Gancao Tang for them. Gancao relaxes the tendons and relieves urgency, while Shaoyao (White Peony Root) clears wind-heat and moistens dryness, allowing the legs to extend naturally. If Stomach Qi is disharmonious and Earth dryness causes delirium, a small amount of Tiaowei Chengqi Tang will harmonize the Stomach Qi. Using Guizhi to induce sweating constitutes the first deviation/error. If one fails to use Ginger and Licorice to restore Yang but instead induces further sweating, or adds burning needles to severely deplete Yang, this constitutes a second deviation/error. In such cases, Sini Tang should be used urgently to restore Yang. The combination of Ginger, Licorice, and Fuzi provides dual warming of Water and Earth.
