甘草（四两炙） 干姜（二两炮）
上二味。以水三升。煮取一升五合。去滓。分温再服。
按此方系因误用桂枝。阳越于上。致有厥逆咽中干。烦躁吐逆谵语诸变。特出此复阳救
逆之
法。观方中甘草倍干姜。专任其甘缓之性。特微加干姜为向导。引阳还返于下。并非资干姜
之辛热以复阳也。用者须识此意。
芍药（四两） 甘草（四两炙）
上二味。以水三升。煮取一升五合。去滓。分温再服。
按阳越于上。既用甘草干姜汤以复其阳。而挛急未解。明是津液不荣经脉。但以芍药甘
草和之。而脚即伸。亦正所以救桂枝之逆也。此法试之颇验。不可以其平易而忽之。
麻黄（二两去节） 赤小豆（一升） 连轺（二两） 杏仁（四十枚去皮尖） 生姜（二两切）
生梓白皮（一升） 甘草（一两炙） 大枣（十二枚）
上八味。以潦水一斗。先煮麻黄。再沸。去上沫。纳诸药。煮取三升。分温三服。半日
服尽。
伤寒瘀热在里。身必发黄。麻黄连轺赤小豆汤主之。按瘀热在里。则伤寒之表邪。亦瘀
而不行
。内外合邪。因致发黄。治亦当内外并解。伤寒解外。仍不离麻黄杏仁甘草之成法。热瘀则
不宜桂枝而改用连轺。以散在经之热。更用赤小豆梓白皮以清在里之热。而复以姜枣和之。
以其发黄从伤寒而来。犹兼半表。亦麻黄汤之变制也。
甘草（四两，炙） 干姜（二两，炮制）
以上两味药。用水三升。煮取一升五合的药液。滤去药渣。分两次温服。
按语：此方是因为误用了桂枝汤，导致阳气浮越于上，从而出现四肢厥冷、咽喉干燥、烦躁、呕吐逆气、胡言乱语等种种变证。特意提出这种回复阳气、挽救逆乱的方法。看方中甘草用量倍于干姜，专门利用其甘缓的特性，略微加入干姜作为向导，引导阳气回归下部。这并不是依靠干姜的辛热之性来回复阳气。使用者必须明白这层意思。
芍药（四两） 甘草（四两，炙）
以上两味药。用水三升。煮取一升五合的药液。滤去药渣。分两次温服。
按语：阳气浮越于上，既然已经用甘草干姜汤来回复其阳气，但肢体拘挛急迫的症状仍未解除，明显是津液不能濡养经脉。只用芍药和甘草调和，脚就能伸展。这也正是为了纠正桂枝汤使用不当造成的逆乱。这种方法试验起来颇为有效，不可以因为它平淡简易而忽视它。
麻黄（二两，去节） 赤小豆（一升） 连轺（二两） 杏仁（四十枚，去皮尖） 生姜（二两，切片）
生梓白皮（一升） 甘草（一两，炙） 大枣（十二枚）
以上八味药。用雨水一斗，先煮麻黄，水再次沸腾后，去掉上面的浮沫，加入其他药物。煮取三升药液，分三次温服。半天内服完。
伤寒病，瘀滞的热邪在体内，身体一定会发黄。麻黄连轺赤小豆汤主治。按语：瘀热在体内，那么伤寒的表邪也瘀滞而不行。内外邪气结合，因此导致发黄。治疗也应当内外同时解决。解除伤寒表邪，仍然不离麻黄、杏仁、甘草的成法。热邪瘀滞则不宜用桂枝，而改用连轺，以疏散在经络中的热邪。再用赤小豆、梓白皮来清除在体内的热邪，最后用生姜、大枣来调和。因为发黄是从伤寒而来，仍然兼有半表证，这也是麻黄汤的变通方制。
Gancao (Licorizae Radix et Rhizoma, four liang, honey-fried) Ganjiang (Zingiberis Rhizoma, two liang, processed)
The above two ingredients. With three sheng of water, decoct to obtain one sheng and five he of liquid. Remove the dregs. Divide into two doses and take warm.
Note: This formula is indicated for cases where Guizhi Tang (Cinnamon Twig Decoction) was mistakenly used, causing Yang Qi to float upward, resulting in various complications such as Jueni (cold extremities), dryness in the throat, irritability, vomiting and regurgitation, and delirious speech. This method is specifically proposed to restore Yang Qi and rescue from reversal. Observing that the dosage of Gancao is double that of Ganjiang, it primarily utilizes the sweet and moderating nature of Gancao, with a slight addition of Ganjiang as a guide to lead Yang Qi back downward. It does not rely on the pungent and hot nature of Ganjiang to restore Yang Qi. Practitioners must understand this intent.
Shaoyao (Paeoniae Radix Alba, four liang) Gancao (Licorizae Radix et Rhizoma, four liang, honey-fried)
The above two ingredients. With three sheng of water, decoct to obtain one sheng and five he of liquid. Remove the dregs. Divide into two doses and take warm.
Note: When Yang Qi floats upward, after using Gancao Ganjiang Tang to restore its Yang, if the cramping and stiffness remain unresolved, it clearly indicates that Body Fluids are failing to nourish the meridians. By harmonizing with Shaoyao and Gancao, the legs can extend. This also serves to correct the reversal caused by the improper use of Guizhi Tang. This method has proven quite effective in practice and should not be neglected due to its simplicity.
Mahuang (Ephedrae Herba, two liang, nodes removed) Chixiaodou (Vigna Semen Rubrum, one sheng) Lianyao (Scutellariae Radix, two liang) Xingren (Armeniacae Semen Amarum, forty pieces, skin and tips removed) Shengjiang (Zingiberis Rhizoma Recens, two liang, sliced)
Shengzibai Pi (Catalpae Cortex, one sheng) Gancao (Licorizae Radix et Rhizoma, one liang, honey-fried) Dazao (Zizyphi Fructus, twelve pieces)
The above eight ingredients. With one dou of rainwater (Liaoshui), first decoct Mahuang. After boiling again, remove the foam on the surface. Add the remaining herbs. Decoct to obtain three sheng of liquid. Divide into three warm doses. Complete the administration within half a day.
In Shanghan (Cold Damage), stagnant heat trapped inside will inevitably cause the body to turn yellow. Mahuang Lianqiao Chixiaodou Tang is the primary treatment. Note: Stagnant heat inside means that the exterior pathogenic factor of Shanghan is also stagnant and fails to circulate. Exterior and interior pathogens combine, leading to jaundice. Treatment should address both interior and exterior simultaneously. To resolve the exterior of Shanghan, the established method of Mahuang, Xingren, and Gancao remains applicable. For stagnant heat, Guizhi is unsuitable; instead, Lianyao is used to disperse heat in the channels. Chixiaodou and Zibai Pi are further employed to clear heat inside, while Jiang and Zao are used to harmonize. Since the jaundice originates from Shanghan, it still involves the half-exterior level, representing a modified variation of Mahuang Tang.
