黄连（六两） 吴茱萸（一两，水煮少时，晒干）
共末为丸。
火噎膈者，此方主之。
此即左金丸也。曰回令者，黄连之苦能胜热，可以回其火令也。以吴茱萸之辛热佐之，
取其反佐以从治尔。
山楂 神曲 砂仁 香附（童便制） 苍术（米泔浸七日） 抚芎 栀子
食噎膈者，此方主之。
食不自膈也，或由气塞，或由火郁，然后停食而作食膈。故用香附、苍术、抚芎以顺气
，栀子以泻火，山楂、神曲、砂仁以消食。昔齐王中子诸婴儿，病烦惫食不下，时呕沫。仓
公视之曰∶食膈病也，作下气汤以饮之。其方今不可考矣。若芩连枳术丸、木香槟榔丸、义
亦近之。
《太平御览》云∶华佗行道，见一人病噎，嗜食而不得下，家人车载欲往就医。佗闻其
呻吟，驻车往视，语之曰∶向来道旁卖饼者，有蒜齑大酢，从取三升饮之，病即当瘥。即如
佗言，立吐蛇一条。悬之车边，欲造佗，佗尚未还，佗家小儿戏门前，迎见，自相谓曰∶客
车边有物，必是遇我公也。疾者前入，见佗壁悬此蛇辈以十数。昆谓蒜味辛热，为阳中之阳，
能令人气实闷乱而自吐，若蛇虫蛊瘕，犹为宜之。《褚氏传》曰∶褚澄以蒜一升，吐李道念
之鸡雏。《齐谐记》云∶郭坦之儿，食蒜一畦，吐消食笼于顷刻。蒜之妙用如此，今之医者，
罕能知之。或问∶何以不用瓜蒂散？余曰∶伤寒内热者，宜吐以瓜蒂散之苦寒。虫瘕痼冷者
，宜吐以蒜酢之辛热。人知苦能吐热，而不知热能吐寒，故特表而出之。
黄连（六两） 吴茱萸（一两，用水煮一段时间，晒干）
研磨成细末，制成丸剂。
对于因火邪导致的噎膈病，此方为主治方。
这就是左金丸。称为“回令”，是因为黄连的苦味能够克制热邪，可以挽回火的正常气机。用吴茱萸的辛热之性来佐助它，是取其反佐之法以顺从病势治疗的意思。
山楂 神曲 砂仁 香附（用童子小便炮制） 苍术（用米泔水浸泡七天） 抚芎 栀子
对于因食积导致的噎膈病，此方为主治方。
食物本身并不会导致噎膈，或者是由气机堵塞引起，或者是由火邪郁结引起，然后导致食物停滞而形成食膈。所以使用香附、苍术、抚芎来理顺气机，栀子来泻火，山楂、神曲、砂仁来消食化积。从前齐王的几个儿子，患病烦躁疲惫，饮食不下，时常呕吐涎沫。仓公观察后说：这是食膈病，制作下气汤给他们服用。那个方子现在已无法考证了。如果是黄芩黄连枳术丸、木香槟榔丸，其义理也相近。
《太平御览》记载：华佗在路上行走，看见一个人患噎病，想吃东西却咽不下去，家人用车载着他打算去就医。华佗听到他的呻吟声，停车前去查看，告诉他说：刚才路边卖饼的人那里有蒜泥醋，你去取三升喝下去，病就会痊愈。那人照华佗说的去做，立刻吐出一条像蛇一样的东西。挂在车边，想要去找华佗，华佗还没回来。华佗家的小孩在门前玩耍，迎面看见，互相说道：客人车边有个东西，一定是遇到了我们的先生。病人进去后，看见华佗墙上挂着十几条这样的蛇状物。我认为蒜味辛热，属于阳中之阳，能让人气实闷乱从而自行呕吐，对于蛇虫蛊瘕等症，尤其适宜。《褚氏传》记载：褚澄用一升蒜，让李道念吐出了鸡雏。《齐谐记》说：郭坦之的儿子，吃了一畦蒜，顷刻间吐出了装满食物的笼子。蒜的妙用如此，现在的医生很少知道这些。有人问：为什么不用瓜蒂散？我说：伤寒内热者，宜用瓜蒂散的苦寒之性来催吐。虫瘕痼冷者，宜用蒜醋的辛热之性来催吐。人们只知道苦味能吐热邪，却不知道热能吐寒邪，所以特意陈述出来。
Coptidis Rhizoma (Liu liang) Evodiae Fructus (Yi liang, boiled in water for a short time, then dried)
Grind into fine powder and make pills.
For Yige (dysphagia with regurgitation) caused by Fire pathogen, this formula is the primary treatment.
This is precisely Zuojin Wan (Left Metal Pill). It is called "Huilin" because the bitter taste of Coptidis Rhizoma can overcome heat, thereby restoring the normal command of Fire. The acrid-hot nature of Evodiae Fructus is used to assist it, taking advantage of the method of counter-assistance to treat according to the disease's nature.
Crataegi Fructus Shenqu (Fermented Medicinal Leaven) Amomi Fructus Rotundus Xiangfu (Cyperi Rhizoma, processed with urine from an uncircumcised boy) Atractylodis Macrocephalae Rhizoma (soaked in rice washing water for seven days) Chuanxiong Rhizoma Gardeniae Fructus
For Yige caused by Food stagnation, this formula is the primary treatment.
Food itself does not cause Yige; it may be due to Qi obstruction or Fire depression, which then leads to food retention and results in Food Yige. Therefore, Cyperi Rhizoma, Atractylodis Macrocephalae Rhizoma, and Chuanxiong Rhizoma are used to smooth Qi; Gardeniae Fructus is used to drain Fire; Crataegi Fructus, Shenqu, and Amomi Fructus Rotundus are used to digest food. In ancient times, several sons of the King of Qi suffered from irritability, exhaustion, inability to eat, and frequent vomiting of saliva. Cang Gong examined them and said: "This is Food Yige disease." He prepared Xiaqi Tang (Qi-Descending Decoction) for them to drink. That formula cannot be verified today. If one considers Huangqin Lianzhang Zhizhu Wan (Scutellaria-Coptis-Aurantium-Zhu Formula) or Muxiang Binglang Wan (Aucklandia-Betel Nut Pill), their principles are also similar.
Taiping Yulan records: Hua Tuo was walking on the road when he saw a person suffering from Yige who desired to eat but could not swallow. His family loaded him onto a cart intending to seek medical help. Hearing his groans, Hua Tuo stopped his carriage, went to examine him, and told him: "Just now, beside the road, there was a pancake seller with garlic vinegar. Go take three sheng [a unit of volume] and drink it, and your illness will surely heal." Following Hua Tuo's advice, he immediately vomited up a snake-like object. Hanging it by the carriage side, he wanted to visit Hua Tuo, but Hua Tuo had not yet returned. Hua Tuo's children were playing at the door; upon seeing the visitor, they said to each other: "There is something by the guest's carriage; he must have met our master." When the patient entered, he saw dozens of such snake-like objects hanging on Hua Tuo's wall. I consider that garlic is acrid and hot, belonging to Yang within Yang. It can cause Qi fullness and mental confusion, leading to spontaneous vomiting. It is particularly suitable for conditions like snake bites, parasites, and abdominal masses. Chu Shi Zhuan states: Chu Cheng used one sheng of garlic to induce Li Daonian to vomit out a chick. Qixie Ji says: Guo Tanzhi's son ate a plot of garlic and instantly vomited out a basket containing digested food in a moment. Such is the wonderful efficacy of garlic. Few modern physicians know this. Someone asked: "Why not use Gou Di San (Melon Seed Powder)?" I replied: "For interior Heat in Shanghan (Cold Damage), one should use the bitter-cold nature of Gou Di San to induce vomiting. For parasitic masses and chronic cold conditions, one should use the acrid-hot nature of garlic and vinegar to induce vomiting. People know that bitterness can induce vomiting of Heat, but do not know that Heat can induce vomiting of Cold. Therefore, I specifically highlight this."
