治疗太阳病。如果症状像疟疾一样，一天发作两次，出汗后就会痊愈。
桂枝（一两十七铢） 芍药（一两六铢） 麻黄（十六铢） 生姜（一两六铢） 杏仁
（十枚） 大枣（十二枚 擘） 甘草（二两 炙）
以上七味药，用水五升，先煮麻黄一两次沸腾，去掉上面的浮沫，加入其他药物，煮取二升，去渣，温服一升，一天服用两次。
歌诀说：一两六铢的芍药和生姜，十六铢的麻黄与杏仁同行。桂枝一两十七铢，甘草二两二铢，大枣匡正辅助。
蔚按语：服用桂枝汤应当让身体微微似有汗出。如果大汗出且脉象洪大，是因为发汗过于急促，表邪虽解但肌腠未解。仍然适宜给予
桂枝汤
以解除表邪。

蔚按语：上一节讲的是服用桂枝汤后大汗出而邪气反而不能净除，适宜仍服用桂枝汤来发汗，或者使用桂枝二麻黄一汤合

Treats Taiyang disease (disease of the Taiyang channel). If the symptoms resemble malaria, occurring twice a day, and relief follows sweating.
Guizhi Tang (Cinnamon Twig Decoction) [Note: The text lists ingredients for Guizhi Er Mahuang Yi Tang but names Guizhi in context of previous/next, here strictly translating ingredients listed]: Guizhi (Cinnamon Twig, 1 liang 17 zhu), Shaoyao (Peony Root, 1 liang 6 zhu), Mahuang (Ephedra Herb, 16 zhu), Shengjiang (Fresh Ginger, 1 liang 6 zhu), Xingren (Apricot Seed, 10 pieces), Dazao (Jujube, 12 pieces, split), Gancao (Licorice Root, 2 liang, honey-fried).
Take the above seven herbs. Add five sheng of water. First boil Mahuang for one or two boils. Remove the foam on the surface. Add the remaining herbs. Boil to obtain two sheng. Remove the dregs. Take one sheng warm. Twice a day.
The song says: Shaoyao and Shengjiang at 1 liang 6 zhu; Mahuang 16 zhu with Xingren go together. Guizhi is 1 liang 17 zhu; Gancao is 2 liang 2 zhu; Dazao assists.
Wei's commentary: When taking Guizhi Tang, slight perspiration should be desired. If profuse sweating occurs with a surging pulse, it is because sweating was too abrupt; the exterior is resolved but the muscle layer remains unresolved. It is still appropriate to administer
Guizhi Tang
to resolve the exterior pathogen.
Treats cases where heat persists after sweating, accompanied by severe irritability and thirst for drinking water.
Zhimu (Anemarrhena Rhizome, 6 liang), Shigao (Gypsum Fibrosum, 1 jin, crushed, wrapped in cotton), Gancao (Licorice Root, 2 liang, honey-fried), Jingmi (Rice, 6 he), Renshen (Ginseng Root, 3 liang).
Take the above five herbs. Add ten dou of water. Boil until the rice is cooked and the decoction is ready. Remove the dregs. Take one sheng warm. Three times a day.
The song says: After taking Guizhi Tang, irritability, thirst, and profuse sweating occur. Fluids are lost, muscle and pores dry up, involving the Yangming channel. Gypsum 1 jin, Zhimu 6 liang, Renshen 3 liang, Gancao 2 liang, Jingmi 6 he, boiled until rice is cooked.
Wei's commentary: The previous section discussed that after profuse sweating from Guizhi Tang, pathogens were not completely cleared, so it was appropriate to continue taking Guizhi Tang to induce sweating, or combine with Guizhi Er Mahuang Yi Tang to address the
muscle and exterior
pathogens. Because pathogens constrain the heart, there is severe irritability. Yangming belongs to dry earth, hence severe thirst. Yang qi is abundant, hence a surging pulse. The main treatment uses the cold nature of Shigao to clear Lung heat, and the bitter taste of Zhimu
to nourish Kidney water. The sweet taste of Gancao and Jingmi, combined with the tonifying effect of Renshen, utilizes cold qi to supplement water to control fire, and sweet taste to tonify Spleen earth to generate Lung metal. Metal is the source of water.
Treats Taiyang disease with fever and aversion to cold, where heat predominates over cold, and the pulse is faint. This indicates "No Yang." Sweating is contraindicated. This decoction is indicated.
Guizhi (Cinnamon Twig, 18 zhu), Shaoyao (Peony Root, 18 zhu), Mahuang (Ephedra Herb, 18 zhu), Gancao (Licorice Root, 18 zhu), Dazao (Jujube, 4 pieces), Shengjiang (Fresh Ginger, 1 liang 2 zhu), Shigao (Gypsum Fibrosum, 24 zhu).
Take the above seven herbs. Chop them. Add five sheng of water. Boil Mahuang for one or two boils. Remove the foam on the surface. Add the other herbs. Decoct to obtain two sheng. Remove the dregs. Take one sheng warm.
This formula
The song says: Guizhi, Shaoyao, Mahuang, and Gancao are each 18 zhu; Shengjiang is 1 liang 2 zhu. Shigao is 24 zhu, Dazao is four pieces. Understand that the meaning of "No Yang" varies.
In the Treatise on Cold Damage, the term "No Yang" refers to Yang qi sinking into Yin. Since there are no signs of Exterior Yang, exterior-releasing sweating is contraindicated. Therefore, Yebip Tang is used. In this formula, Shigao has a texture
Wei's commentary: The dosages in this formula are very light, generally intended for patients with mild pathogens. The Taiyang channel is governed by Yang. The description "heat predominates over cold" implies Yang qi desires to overcome the pathogen but is not yet excessively strong; thus, Mahuang should not be used to induce
profuse sweating. Regarding the term "No Yang," some refer to Yuan Yin and Yuan Yang (Primordial Yin and Primordial Yang), some to Zang-Fu organs, some to Interior-Exterior, some to Cold-Heat, and some to Pathogenic-Righteous factors.
