乌梅丸用细辛桂。人参附子椒姜继。黄连黄柏及当归。温脏安蛔寒厥剂。
阳明经的胃络从头向下行走。如果气机上逆，就会发生呕吐。少阳病引起的呕吐伴有口苦，适用小柴胡汤。胸中有热邪，适用黄连类方剂。心下（胃脘部）有水饮停留，适用茯苓甘草汤。先呕吐后口渴，适用五苓散。发汗后出现虚烦，适用竹叶石膏汤。栀子豉汤也尤为适宜食用/服用。
有声音且有物吐出称为“呕”。这就是海藏（张元素）和东垣（李杲）所说的“干呕”。然而干呕的症状也不尽相同。有的因太阳病自汗导致干呕，适用桂枝汤主治。有的因水气在表导致干呕，适用小青龙汤主治。有的因水气在里导致干呕，适用十枣汤主治。有的因少阴病下利导致干呕，适用姜附汤主治。有的因厥阴病吐涎沫导致干呕，适用吴茱萸汤主治。大抵上，干呕与呕吐不同，应当分别治疗。
小青龙汤由桂枝、麻黄、甘草、半夏、细辛、炒芍药、干姜、五味子组成，可同煎。水饮停聚在心下时此方效果好。十枣汤中使用大枣，配合芫花、大戟、甘遂效果良好。干呕伴胁痛宜煎服此方，对于伏饮停痰之症不可或缺。吴茱萸汤含有人参、大枣，重用生姜以温胃效果佳。阳明寒呕、少阴下利、厥阴病症，皆能以此方解除疼痛并保全正气。
火邪劫夺津液或导致惊狂。逼迫出汗、烧针灼艾会使阳气外越。烦躁不安用什么药治疗？可用柴胡加龙骨牡蛎汤煎服。
所谓火邪惊狂，是医家使用火熏、火熨迫令出汗，以及烧针、灼艾所致。患者出现亡阳症状，躁动不安，卧起不宁，宜用柴胡加龙骨牡蛎汤主治。因为柴胡、龙骨、牡蛎能除烦、敛气并镇惊。
胃冷且再次加重出汗，因而形成蛔厥，吐出长虫。病源本属于厥阴症，宜用乌梅丸与理中汤治疗。
所谓蛔厥，病位在厥阴。蛔虫进入上膈则引起疼痛，片刻后又停止。进食后会呕吐，并且感到心烦，这是因为蛔虫闻到食物的气味又出来了。这是脏寒应当自行吐出蛔虫的情况，给予乌梅丸以温脏安蛔。也有因胃冷而吐蛔虫的，这是由于发汗所致，病位在阳明。宜用理中汤加入炒川椒五粒、槟榔五分，吞服乌梅丸。乌梅丸在辛味和酸味入肝的药物中，微微加入苦寒药物，接纳上逆的阳邪，使其顺行而下。名为安蛔，实际上是安胃。所以该方主治久痢，见到阴阳之气不相顺接，而出现下利症状的，都可以用此方概括治疗。
The stomach meridian of the Yangming channel descends from the head. When Qi rebels upward, vomiting occurs. Vomiting associated with bitter taste in Shaoyang disease is treated with Xiao Chai Hu Tang (Minor Bupleurum Decoction). Heat in the chest is treated with formulas containing Huang Lian (Coptidis Rhizoma). Fluid retention under the heart (epigastrium) is treated with Fu Ling Gan Cao Tang (Poria and Licorice Decoction). Vomiting followed by thirst is treated with Wu Ling San (Five-Ingredient Powder with Poria). Restlessness after sweating is treated with Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction); Zhi Zi Chi Tang (Gardenia and Fermented Soybean Decoction) is also highly suitable.
Vomiting with sound and matter is called "Ou" (vomiting). This is what Haicang (Zhang Yuansu) and Dongyuan (Li Gao) referred to as "Gan Ou" (dry heaving). However, symptoms of dry heaving vary. Dry heaving due to spontaneous sweating in Taiyang disease is primarily treated with Gui Zhi Tang (Cinnamon Twig Decoction). Dry heaving due to fluid retention in the exterior is primarily treated with Xiao Qing Long Tang (Minor Blue-Green Dragon Decoction). Dry heaving due to fluid retention in the interior is primarily treated with Shi Zao Tang (Ten Jujube Decoction). Dry heaving associated with diarrhea in Shaoyin disease is primarily treated with Jiang Fu Tang (Ginger and Aconite Decoction). Dry heaving associated with drooling in Jueyin disease is primarily treated with Wu Zhu Yu Tang (Evodia Decoction). Generally, dry heaving differs from vomiting and should be treated differently.
Xiao Qing Long Tang consists of Gui Zhi (Cinnamomi Ramulus), Ma Huang (Ephedrae Herba), Gan Cao (Glycyrrhizae Radix et Rhizoma), Ban Xia (Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine), Xi Xin (Asari Radix et Rhizoma), fried Shao Yao (Paeoniae Radix Alba), Gan Jiang (Zingiberis Rhizoma), and Wu Wei Zi (Schisandrae Fructus), which are decocted together. This formula is effective for fluid retention in the epigastrium. Shi Zao Tang uses Da Zao (Jujubae Fructus) combined with Yuan Hua (Genkwa Flos), Da Ji (Euphorbiae Pekinensis Radix), and Gan Sui (Kansui Radix). It is suitable for dry heaving with hypochondriac pain and is indispensable for treating latent fluid retention and phlegm. Wu Zhu Yu Tang contains Ren Shen (Ginseng Radix et Rhizoma) and Da Zao, with a heavy use of Sheng Jiang (Zingiberis Rhizoma Recens) to warm the stomach effectively. It resolves pain and preserves healthy Qi for cold vomiting in Yangming, diarrhea in Shaoyin, and disorders in Jueyin.
Fire pathogen depletion or convulsive fright. Forced sweating and moxibustion cause Yang to escape. What medicine treats restlessness? Chai Hu Jia Long Gu Mu Li Tang (Bupleurum Decoction plus Dragon Bone and Oyster Shell) can be decocted and taken.
Fire pathogen-induced convulsive fright results from physicians using fire fumigation, fire ironing to force sweating, and burning needles or moxibustion. The patient exhibits loss of Yang, agitation, and restlessness in lying down or sitting up. It is primarily treated with Chai Hu Jia Long Gu Mu Li Tang. This is because Chai Hu (Bupleuri Radix), Long Gu (Fossilia Ossis Mastodi), and Mu Li (Ostrea Concha) can relieve irritability, consolidate Qi, and calm fright.
Cold stomach exacerbated by excessive sweating leads to Ascaris syncope (Hui Jue), with expulsion of long worms. The pathology originates in Jueyin disease; Wumei Wan (Mume Pill) and Lizhong Tang (Regulate the Middle Decoction) are indicated.
Ascaris syncope involves Jueyin pathology. When ascarides enter the upper diaphragm, pain occurs, ceasing momentarily. Eating induces vomiting and vexation, as the ascarides return upon smelling food. This indicates cold in the zang organs causing spontaneous expulsion of ascarides; Wumei Wan is given to warm the zang and pacify ascarides. There are also cases of vomiting ascarides due to cold stomach caused by sweating, involving Yangming pathology. Lizhong Tang is used with five grains of chao Chuan Jiao (Sichuan Pepper) and 0.5 fen of Bing Lang (Arecae Semen), swallowed with Wumei Wan. Wumei Wan adds slight bitter-cold herbs to acrid-sour liver-entering drugs to accommodate rebellious Yang pathogens and guide them downward. Named "pacifying ascarides," it essentially "calms the stomach." Thus, it mainly treats chronic dysentery and conditions where Yin and Yang fail to connect smoothly, presenting with diarrhea; such cases can all be managed by this formula.
Wumei Wan contains Xi Xin (Asari Radix et Rhizoma), Gui Zhi (Cinnamomi Ramulus), Ren Shen (Ginseng Radix et Rhizoma), Fu Zi (Aconiti Lateralis Radix Praeparata), Jiao (Zanthoxyli Pericarpium), Gan Jiang (Zingiberis Rhizoma), Huang Lian (Coptidis Rhizoma), Huang Bai (Phellodendri Cortex), and Dang Gui (Angelicae Sinensis Radix). It is a formula for warming the zang, pacifying ascarides, and treating cold syncope.
