发汗之后，或经过攻下治疗，不可再使用桂枝汤。如果出现出汗且伴有气喘，身体没有明显高热者，可以给予麻黄杏仁甘草石膏汤（Mahuang Xingren Gancao Shigao Tang）。张仲景凡是提到“汗后”、“下后”，是指表邪已经完全解除，仅剩下一个症状而已，所以说不能再使用桂枝汤。如今在发汗和攻下之后出现气喘，身体没有大热，这是上焦的残余病邪尚未解除，应当给予麻黄杏仁甘草石膏汤来疏散它。至于桂枝加厚朴杏子汤（Guizhi Jia Houpo Xingzi Tang），是用于桂枝证完全具备，并且兼见气喘的情况。如今身体没有大热，只是出汗且气喘，不应当用桂枝来止汗，而应当用麻黄来发散表邪，用杏仁和石膏来清泄里热。等到表和里的病邪全部清除，那么气喘和出汗的症状自然就会停止，无需专门去治疗喘和汗。
发汗过多，病人双手交叉按压在心胸部，感到心下悸动，喜欢被按压，此方主治。发汗过多导致阳气亡失，则胸中气机怯弱，所以双手交叉按压心部；心悸且喜欢被按压，是因为虚损的缘故，所以喜欢被按压。给予桂枝的辛味，入肺经而益气；甘草的甘味，归脾经而缓和急迫。
发汗之后，病人感到脐下悸动，这是即将发生奔豚病（Ben Tun, a condition characterized by a sensation of Qi rushing upward from the lower abdomen）的前兆，此方主治。甘澜水的制作方法：取适量水放入大盆中，用勺子反复扬水，直到水面出现无数珍珠般的小水泡（称为“甘澜水”）。奔豚病发作时，气感从少腹向上冲至心胸，这是因为水邪凌犯心火所致。用茯苓来伐除水邪，用桂枝来宣泄奔豚之气，甘草和大枣的甘平之性，能资助胃土以制约肾水。使用甘澜水的原因，是取其水性灵动不止的特性，以调理停滞的水湿。
太阳病发汗之后，出现腹部胀满，此方主治。张仲景凡是提到“发汗后”，是指体表没有表证，体内也没有其他邪气，仅有腹部胀满实证。这是由于脾胃津液不足，气机涩滞不通，壅塞而导致胀满。只需给予此方，调和脾胃，那么浊气自然下降，胀满也就自行消除。
Ephedrae Herba (Mahuang, 麻黄), Armeniacae Semen Amarum (Xingren, 杏仁), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草), Gypsum Fibrosum (Shigao, 石膏)
After sweating therapy or purgation therapy, Guizhi Tang (Cinnamon Twig Decoction) must not be administered again. If there is sweating accompanied by wheezing and no significant high fever, Mahuang Xingren Gancao Shigao Tang (Ephedra, Apricot Seed, Licorice, and Gypsum Decoction) may be given. Zhang Zhongjing states that whenever he mentions "after sweating" or "after purgation," it implies that the exterior pathogenic factors have been completely resolved, leaving only one remaining symptom; therefore, he says Guizhi Tang should not be used again. In the current case, after sweating and purgation, wheezing occurs and the body lacks significant heat, indicating that residual pathogenic factors in the Upper Jiao (Upper Burner) have not yet been resolved. One should administer Mahuang Xingren Gancao Shigao Tang to disperse them. Guizhi Jia Houpo Xingzi Tang (Cinnamon Twig Decoction with Magnolia Bark and Apricot Seed) is indicated when all symptoms of a Guizhi pattern are present and wheezing is added. Since there is no significant heat here, but only sweating and wheezing, one should not use Cinnamon Twig to stop sweating, but rather use Ephedra to release the exterior, and combine Apricot Seed and Gypsum to clear the interior. Once the exterior and interior pathogenic factors are thoroughly eliminated, the wheezing and sweating will cease spontaneously without specific treatment for these symptoms.
Cinnamomi Ramulus (Guizhi, 桂枝), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草)
Excessive sweating leads to a patient crossing their hands over the heart region, experiencing palpitations in the epigastric area, and desiring pressure upon it. This decoction is the primary treatment. Excessive sweating causes loss of Yang Qi, leading to timidity of Qi in the chest. Hence, the patient crosses their hands over the heart. Palpitations that desire pressure occur due to deficiency, which is why pressure is preferred. The acrid nature of Cinnamon Twig enters the Lung Meridian to benefit Qi; the sweet nature of Licorice enters the Spleen to moderate tension.
Poria (Fuling, 茯苓), Cinnamomi Ramulus (Guizhi, 桂枝), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草), Ziziphus Jujubae Fructus (Dazao, 大枣)
After sweating therapy, if the patient experiences palpitations below the umbilicus, this indicates the impending onset of Ben Tun (Rushing Pig, a condition characterized by a sensation of Qi rushing upward from the lower abdomen). This decoction is the primary treatment. Method for preparing Ganlan Water: Place water in a large basin and ladle it repeatedly until numerous pearl-like bubbles appear on the surface. When Ben Tun attacks, the sensation rises from the lower abdomen to the heart, caused by Water Pathogen overwhelming Fire. Poria is used to drain the Water Pathogen; Cinnamon Twig is used to vent the Ben Tun. The sweet and neutral properties of Licorice and Jujube assist Stomach Earth to calm Kidney Water. Ganlan Water is used because its dynamic nature helps resolve stagnant water.
Magnoliae Officinalis Cortex (Houpo, 厚朴), Zingiberis Recens Rhizoma (Shengjiang, 生姜), Ginseng Radix (Renshen, 人参), Pinelliae Rhizoma Preparatum (Banxia, 半夏), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草)
After sweating therapy for a Taiyang Disease (Sunyang Bing, 太阳病), abdominal fullness occurs. This decoction is the primary treatment. Whenever Zhang Zhongjing mentions "after sweating," it implies that there are no exterior patterns and no other internal pathogens, only abdominal fullness and excess. This results from insufficient fluids in the Spleen and Stomach, causing Qi stagnation and obstruction, leading to distension. Administering this decoction harmonizes the Spleen and Stomach, allowing turbid Qi to descend naturally, thereby resolving the fullness.
