经
桂枝一两十七铢（去皮），芍药一两六铢，甘草一两二铢（炙），麻黄十六铢（去节），杏仁十六枚。
以上七味药，用水五升，先煮麻黄一二沸，去掉水面上的浮沫〔煎煮法〕，再加入其他药物，煮取药液二升，滤去药渣〔煎煮法〕，温服。
桂枝的用量比标准方多，麻黄的用量较少，这是通过喝热粥来辅助发汗的变通之法。桂枝汤减量使用原方的四分之二，麻黄汤减量使用原方的四分之一。
桂枝十八铢（去皮），芍药十八铢，甘草十八铢，生姜一两二铢，大枣四枚（掰开），麻黄十八铢。
以上七味药，切碎〔炮制法〕，用水五升，先煮麻黄一二沸，去掉水面上的浮沫〔煎煮法〕，再加入其他药物，煮取药液二升，滤去药渣〔煎煮法〕，温服一升〔服用法〕。本方应当裁减为越婢汤与桂枝汤合饮一升〔服用法〕，现在合并为一个方剂，名为桂枝二越婢一汤。
桂枝二越婢一汤，治疗脉象微弱且无阳证。所谓“无阳”，是指阳气分中津液亡失的意思，因此用桂枝汤照原方剂量使用四分之二以调和营卫，使脉象恢复。
葛根四两，麻黄三两（去节），桂枝二两（去皮），白芍二两，甘草二两（炙），生姜三两（切片）。
以上七味药，切碎〔炮制法〕，用水一斗，先煮麻黄、葛根，水量减少二升，去掉浮沫〔煎煮法〕，再加入其他药物，煮取药液三升，滤去药渣〔煎煮法〕，温服一升〔服用法〕。服药后覆盖衣被使身体微微似有汗出〔护理法〕，不需要喝热粥。其余调养方法及禁忌事项如同桂枝汤的法度。
葛根汤，即桂枝汤加入麻黄，并加倍使用葛根，用以祛除营分之实邪，是对麻黄汤和桂枝汤法度的微小变化。唯独葛根和麻黄用于治疗营卫之实证，……则……者……经……
Guizhi (Cinnamon Twig) 1 liang and 17 zhu (peeled), Shaoyao (White Peony Root) 1 liang and 6 zhu, Gancao (Licorice Root) 1 liang and 2 zhu (roasted), Mahuang (Ephedrae Herba) 16 zhu (nodes removed), Xingren (Prunus Armeniaca Seed) 16 pieces.
The above seven ingredients are decocted with five sheng of water. First, boil Mahuang for one or two boils, remove the foam on the surface [decoction method], then add the remaining herbs, and decoct to obtain two sheng of liquid. Strain off the dregs [decoction method], and take warm.
The dosage of Guizhi is greater than standard, while that of Mahuang is smaller; this is a modified method of assisting diaphoresis by drinking hot congee. The Guizhi Tang (Cinnamon Twig Decoction) is reduced to two-fourths of its original formula, and the Mahuang Tang (Ephedra Decoction) is reduced to one-fourth of its original formula.
Guizhi (Cinnamon Twig) 18 zhu (peeled), Shaoyao (White Peony Root) 18 zhu, Gancao (Licorice Root) 18 zhu, Shengjiang (Fresh Ginger Rhizome) 1 liang and 2 zhu, Dazao (Jujube Fruit) four pieces (broken open), Mahuang (Ephedrae Herba) 18 zhu.
The above seven ingredients are crushed [preparation method], decocted with five sheng of water. First, boil Mahuang for one or two boils, remove the foam on the surface [decoction method], then add the remaining herbs, and decoct to obtain two sheng of liquid. Strain off the dregs [decoction method], and take one sheng warm [administration method]. This formula should ideally be adjusted to drink one sheng of a combination of Yebiao Tang (Yuebi Decoction) and Guizhi Tang (Cinnamon Twig Decoction) [administration method]; now they are combined into one formula, named Guizhi Er Yuebi Yi Tang (Two Parts Cinnamon Twig and One Part Yuebi Decoction).
Guizhi Er Yuebi Yi Tang treats a faint pulse and absence of Yang syndrome. "Absence of Yang" refers to the loss of fluids in the Yang aspect; therefore, Guizhi Tang (Cinnamon Twig Decoction) is used at two-fourths of the original dosage to harmonize Ying and Wei, allowing the pulse to recover.
Gegen (Puerariae Lobatae Radix) 4 liang, Mahuang (Ephedrae Herba) 3 liang (nodes removed), Guizhi (Cinnamon Twig) 2 liang (peeled), Baishao (White Peony Root) 2 liang, Gancao (Licorice Root) 2 liang (roasted), Shengjiang (Fresh Ginger Rhizome) 3 liang (sliced).
The above seven ingredients are crushed [preparation method], decocted with one dou of water. First, boil Mahuang and Gegen until the volume decreases by two sheng, removing the foam [decoction method], then add the remaining herbs, and decoct to obtain three sheng of liquid. Strain off the dregs [decoction method], and take one sheng warm [administration method]. Cover the patient to induce a slight sweating [nursing method]; there is no need to drink hot congee. Rest and dietary precautions follow the methods and contraindications of Guizhi Tang (Cinnamon Twig Decoction).
Gegen Tang (Kudzu Decoction) is Guizhi Tang (Cinnamon Twig Decoction) with added Mahuang (Ephedrae Herba) and doubled Gegen (Puerariae Lobatae Radix), used to dispel excess in the Ying level, representing a slight modification of the methods of Mahuang Tang (Ephedra Decoction) and Guizhi Tang (Cinnamon Twig Decoction). Specifically, Gegen and Mahuang treat excess in Ying and Wei... then... those... meridians...
