芒硝治久热胃闭，少阳热已入胃而犹潮热、胁满者，则热在胃而证未离少阳，治亦仍用
柴胡，但加芒硝以涤胃热，仍从少阳之枢外出，使其中外荡涤无遗，乃为合法。钱塘张锡驹
云∶应以大柴胡加芒硝，其理亦通，姑志之。
栝蒌实一枚（去皮），甘遂四两，桂枝四两（去皮），人参四两，大枣十二枚（掰开）。
以上五味药，用水七升，煮取三升，滤去药渣，温服一升。若胸中没有坚硬结聚，不要服用此方。
大陷胸汤有两个方子，一个是攻陷中焦和下焦的邪气，这个是攻陷上焦和中焦的邪气。栝蒌能陷下胸中的痰饮，甘遂能陷下经络中的清化之邪。
葶苈子半升（炒制），杏仁半升（去皮尖，炒至黑色），大黄八两（去皮），芒硝半升。
以上四味药，将大黄、葶苈子两味捣筛成散剂，把杏仁、芒硝混合研磨如脂状，调和后取如弹丸大小的一枚药团。另外单独捣甘遂末一钱匕，加入白蜜二合，水二升，煮取一升，一次性温服。过一夜大便才会通下。如果未通下，再服用一次，以大便通下为有效。禁忌事项同一般服药法。
大陷胸丸，药力从高处分消向下，三焦同时攻逐。结胸证出现项背强直，说明邪气占据太阳经的高位，所以用葶苈、杏仁来陷下上焦的邪气。
柴胡八两，黄芩三两，半夏半升，生姜五两（切片），大枣十二枚（掰开），芍药三两，枳实四枚（炙）。
以上八味药，用水一斗二升，煮取六升，滤去药渣后再煎浓缩，温服一升，每日三次服用。
大柴胡汤，属于泻下之法。前文章节说少阳病不可使用下法，而这里又提出下法，是因为热邪从少阳传来，结聚在阳明经。
柴胡二两十六铢，黄芩一两，人参一两，甘草一两（炙），生姜一两（切片），半夏五枚，大枣四枚。
以上八味药，用水四升，煮取二升，滤去药渣，分两次服用。以症状解除为痊愈，若未解除，继续煎服。
芒硝治疗久热导致的胃气闭塞，如果少阳的热邪已经传入胃腑，仍然出现潮热、胁肋胀满的症状，那么热邪在胃，但证候仍未脱离少阳，治疗依然使用柴胡，只是加入芒硝来涤荡胃热，仍然顺着少阳的枢机向外透达，使体内内外荡涤干净无遗，这才是合法的治疗。钱塘人张锡驹说：应该用大柴胡汤加芒硝，这个理论也是通的，暂且记录下来。
Gualou Fruit (Trichosanthis Fructus) one piece (remove skin), Kansui Root (Kansui Radix) four liang, Cinnamon Twig (Cinnamomi Ramulus) four liang (remove bark), Ginseng Root (Ginseng Radix) four liang, Jujube (Zizyphi Fructus) twelve pieces (split open).
Take the above five herbs, add seven sheng of water, decoct to obtain three sheng, remove the dregs, and take one sheng warm. Do not administer if there is no hardness in the chest.
There are two formulas for Daxiexiong Tang (Major Downward Draining Chest Decoction); one drains pathogenic factors from the Middle and Lower Jiao, while this one drains pathogenic factors from the Upper and Middle Jiao. Gualou sinks phlegm in the chest, and Kansui sinks clear-transforming pathogens in the meridians.
Levisticum Seed (Lepidii Semen) half sheng (stir-fried), Apricot Seed (Armeniacae Semen Amarum) half sheng (remove skin and tips, stir-fry until black), Rhubarb (Rhei Radix et Rhizoma) eight liang (remove skin), Mirabilite (Natrii Sulfas) half sheng.
Take the above four herbs, pound and sieve Rhubarb and Levisticum Seed into powder. Mix Apricot Seed and Mirabilite and grind them together until they resemble paste. Combine with the powder and form a pill the size of a bullet. Independently pound Kansui Root into fine powder, one qianbi. Add two he of white honey and two sheng of water. Decoct to obtain one sheng. Take all at once warm. Bowel movement will occur after one night. If it does not move, take another dose. The effect is achieved when bowel movements occur. Observe dietary restrictions as per general medication rules.
Daxiexiong Wan (Major Downward Draining Chest Pill) acts by descending from high positions, attacking all three Jiao simultaneously. In Jie Xiong (Chest Binding) presenting with stiffness of the neck and back, the pathogen occupies the high position of the Taiyang Meridian. Therefore, Levisticum Seed and Apricot Seed are used to sink pathogens in the Upper Jiao.
Bupleurum Root (Bupleuri Radix) eight liang, Scutellaria Root (Scutellariae Radix) three liang, Pinellia Tuber (Pinelliae Rhizoma) half sheng, Fresh Ginger (Zingiberis Rhizoma Recens) five liang (sliced), Jujube (Zizyphi Fructus) twelve pieces (split open), White Peony Root (Paeoniae Radix Alba) three liang, Immature Bitter Orange (Aurantii Fructus Immaturus) four pieces (roasted).
Take the above eight herbs, add twelve dou of water, decoct to obtain six sheng, remove dregs, and continue decocting. Take one sheng warm, three times a day.
Da Chaihu Tang (Major Bupleurum Decoction) belongs to the purgative method. Previous chapters stated that Shaoyang syndrome should not be treated with purgation, yet here a purgative method is presented because heat pathogenic factors have come from Shaoyang and accumulated in Yangming.
Bupleurum Root (Bupleuri Radix) two liang sixteen zhu, Scutellaria Root (Scutellariae Radix) one liang, Ginseng Root (Ginseng Radix) one liang, Licorice Root (Glycyrrhizae Radix et Rhizoma) one liang (roasted), Fresh Ginger (Zingiberis Rhizoma Recens) one liang (sliced), Pinellia Tuber (Pinelliae Rhizoma) five pieces, Jujube (Zizyphi Fructus) four pieces.
Take the above eight herbs, add four sheng of water, decoct to obtain two sheng, remove dregs, and divide into two doses. Recovery is indicated by symptom resolution; if unresolved, prepare and take another dose.
Mirabilite (Natrii Sulfas) treats chronic heat causing stomach closure. If Shaoyang heat has entered the Stomach but tidal fever and hypochondriac fullness persist, the heat is in the Stomach, yet the syndrome has not left Shaoyang. Treatment still utilizes Bupleurum Root, but adds Mirabilite to cleanse Stomach heat. This allows the pathogen to exit outward via the pivot mechanism of Shaoyang, ensuring thorough cleansing inside and out, which constitutes the correct method. Zhang Xiju from Qiantang stated: Da Chaihu Tang plus Mirabilite should be used; this reasoning is also valid. I record it here for reference.
