浓朴麻黄汤，大、小青龙之变方也；咳而上气作声，脉浮者，是属外邪鼓动下焦之水气上逆

仍从肺经泄热存阴，细辛、半夏深入阴分，祛散水寒，干姜、五味摄太阳而监制其逆，一举
而泄热下气、散邪固本之功皆备，则肺经清肃之令自行，何患咳逆上气作声有不宁谧者耶？

射干三两，麻黄四两，紫菀三两，款冬花三两，北细辛三两，五味子半升，半夏半升，生姜（适量）。
以上九味药，用水一斗二升，先煮麻黄至沸腾两次，撇去浮沫，加入其余药物，煎煮取汁三升，分三次温服。
射干汤，是以苦、辛、温性入肺经的药物组成的复方。喉中发出像水鸡（青蛙）一样的叫声，是痰气进出咽喉时发出的咯鸣声。这是由于肺中虚冷，阳气不能宣通所致，需用泻法治疗以清肺经之寒。
厚朴五两，麻黄四两，石膏（如鸡蛋大小），杏仁半升，半夏半升，干姜二两，细辛二两，小麦（适量）。
以上九味药，用水一斗二升，先煮小麦至熟，滤去渣滓，加入其余药物，煎煮取汁三升，每次温服一升，每日服用三次。
厚朴麻黄汤，是大青龙汤和小青龙汤的变方。咳嗽且气逆上冲伴有声音，脉象浮的，属于外邪鼓动下焦水气上逆。此证与桂枝、芍药、甘草调和营卫无关，所以加厚朴以降胃气上逆，加小麦以抑制心气乘犯肺金。麻黄、杏仁、石膏仍从肺经泄热存阴，细辛、半夏深入阴分，祛除散水寒之邪，干姜、五味子收敛太阳之气并监制其逆乱，一举而具备泄热下气、散邪固本的功效，那么肺经清肃的功能自然恢复，何必担心咳逆上气伴有声音而不安宁呢？
麦门冬七升，半夏一升，人参三两，甘草二两，粳米三合，大枣十二枚。
以上六味药，用水一斗二升，煎煮取汁六升，每次温服一升，白天服用三次，夜间服用一次。
麦门冬汤，是从胃生津液以救燥，治疗虚火上冲的方剂。《金匮要略》说：“火逆上气，咽喉不利”，旨在止逆下气。故病属虚火，忌用冷药。枣（大枣）能补脾益气，缓和急迫。
Shegan San liang, Mahuang Si liang, Ziwan San liang, Kuandonghua San liang, Beixixin San liang, Wuweizi Ban sheng, Banxia Ban sheng, Shengjiang (appropriate amount).
The above nine herbs are decocted with one dou and two sheng of water. First, boil Mahuang until it boils twice, skim off the foam on the surface, then add the remaining herbs. Decoct to obtain three sheng of liquid, and take in three divided warm doses.
Shegan Tang is a compound formula composed of herbs with bitter, acrid, and warm properties that enter the Lung meridian. The sound in the throat resembling that of a water frog indicates rattling caused by phlegm and qi moving in and out of the throat. This condition arises from cold in the Lung due to the failure of Yang qi to circulate freely; it requires a draining method to clear cold from the Lung meridian.
Houpu Five liang, Mahuang Si liang, Shigao (size of a chicken egg), Xingren Ban sheng, Banxia Ban sheng, Ganjiang Er liang, Xixin Er liang, Xiaomai (appropriate amount).
The above nine herbs are decocted with one dou and two sheng of water. First, boil Xiaomai until cooked, strain to remove the dregs, then add the remaining herbs. Decoct to obtain three sheng of liquid, take one sheng warm per dose, three times daily.
Houpu Mahuang Tang is a modified formula derived from Da Qinglong Tang and Xiao Qinglong Tang. Cough accompanied by rebellious Qi rising with audible sounds and a floating pulse indicate that external pathogens are stirring up Water Qi from the Lower Jiao causing it to rebel upward. This pattern is unrelated to the harmonizing of Ying and Wei using Guizhi, Shaoyao, and Gancao. Therefore, Houpu is added to direct Stomach Qi downward, and Xiaomai is added to restrain Heart Qi from overacting upon the Lungs. Mahuang, Xingren, and Shigao continue to clear heat and preserve Yin from the Lung meridian. Xixin and Banxia penetrate into the Yin aspect to dispel Water-Cold. Ganjiang and Wuweizi secure Taiyang Qi and monitor/control rebellion. In one move, this formula achieves the effects of clearing heat, directing Qi downward, expelling pathogens, and consolidating the root. Thus, the clear and descending function of the Lung meridian restores itself naturally. Why worry about cough and rebellious Qi with sounds being unsettled?
Maidong Seven sheng, Banxia One sheng, Renshen San liang, Gancao Er liang, Jingmi San he, Dazao Twelve pieces.
The above six herbs are decocted with one dou and two sheng of water. Decoct to obtain six sheng of liquid. Take one sheng warm per dose, three times during the day and once at night.
Maidong Tang is a formula that generates fluids from the Stomach to rescue dryness, treating rebellious Qi caused by deficient Fire. The *Jin Gui Yao Lue* states: "Rebellious Qi due to Fire obstruction, with difficulty in the throat," aiming to stop rebellion and direct Qi downward. Therefore, the disease belongs to deficient Fire, and cold medicines should be avoided. Dates (Dazao) tonify Spleen Qi and ease urgency.
