呕吐病原不一，治者要辨根由，呕则声物一时有，有物无声
曰吐。更有有声无物，此名哕而干呕，又当辨症药分投，有甚难为
措手。
冷吐乳食不化，腹胀喘急无时，面白眼慢气多吁，吐有夹食
清水。此因风寒入胃，或食生冷伤亏。抑伤宿乳胃中虚，不纳乳食
吐出。
热吐唇红面赤，乳食入而虽消，吐物黄色遍身烧，大热渴多
烦躁。此因暑气在胃，或食热物煎熬，胃气因热不和调，气逆遂成
吐了。
积吐如何分晓，眼胞浮面微黄，足冷肚热异寻常。昼轻夜重
魔瘴。宿冷滞在脾胃，故吐黄酸水浆，或吐酸馊气难当(22)，此
伤宿食形状。
小儿伤乳吐者，形症更要消详，乳才哺后吐浪荡，或少停而
吐止。此因乳食无度，脾气弱不能当，速将空乳令儿尝，乳节吐止
为上。
吐症既分明白，治法犹贵精微，冷吐理中汤最宜，热吐五苓
去桂。积吐九转灵应，下后积术调之，伤乳而吐药方奇，三棱散子
为最。
呕吐乳食不纳，任是汤药难尝，此谓阴盛隔孤阳，时医却无
主张。参术煨姜熟附，乌梅童便尤良，猪胆同入慢消详，此法应如
影响。
吐呕诸药不纳。我有绝胜奇方，定吐饮子妙非常。半夏官桂
二样，生姜独宜多取，甘草少用为良，根据方制造水煎尝，仍用生
姜为上。
一等蛔虫吐出，此为蛔多厥阴，乌梅丸子效如神，一服蛔安
吐定。又有咳而吐者，化痰顺气须明，如常呕吐只胃苓，汤用生
姜作引。
呕吐不止之症，分明说与医人，如服正药俱无灵，更加烦躁
乱闷。呕吐只是不止;目睛上窜须危，头往上仰魄如飞，只好安
排后事。
再附恶心一症，有痰有热有虚，三症生姜通用之。药宜随症
区处。若是胃中有热，二陈加上苓连，姜汁炒过共同煎，各用一钱
最验。
此药性味平和，寒证热证均可通用。
陈皮，半夏（用姜汁浸泡七次），白茯苓、甘草。生姜三片作为引经药，用水一盅煎煮后服用。如果呕吐严重，加入白术、煨干姜，这两味是治疗呕吐必用的药物。兼有热象而呕吐的，加入煨干姜、炒黄连。如果是伤食引起的，加入神曲、炒麦芽、砂仁、香附子、山楂。这五味是消食导滞必用的药物。
祖传治疗呕吐，只用胃苓丸，用煨干姜煎汤吞服来治疗，不分寒证热证。
凡是呕吐不止，服药无效且出现烦闷症状的，属于不治之症；呕吐不止，眼球上翻的，属于不治之症；头向后仰的，属于不治之症。
西江月词：
呕吐的病因不一，治疗者必须辨别根源。呕是指声音和食物同时发出，有物无声称为吐。更有声音而无食物的情况，这名叫哕（干呕），又应当辨证施治，用药分开投送，有时确实难以下手。
冷吐：乳食不消化，腹胀气喘急促无休止，面色苍白，眼神呆滞，气多叹息，呕吐物夹杂未消化的食物和清水。这是因为风寒侵入胃中，或者食用生冷食物损伤了脾胃。或者是宿乳积滞在胃中导致胃虚，不能容纳乳食而吐出。
热吐：嘴唇红，面色赤，乳食进入后虽然被消化，但呕吐物呈黄色，全身发热，大渴，烦躁不安。这是因为暑气在胃中，或者食用热性食物煎熬，胃气因热而不调和，气机上逆遂成呕吐。
积吐如何分辨？眼睑浮肿，面色微黄，脚冷肚子热异于平常，白天轻晚上重，如同被邪祟迷惑。这是宿冷停滞在脾胃，所以呕吐黄酸水浆，或者呕吐酸腐气味难忍，这是伤及宿食的形态。
小儿伤乳呕吐，形症更要仔细详察，哺乳后立即呕吐，或者稍停片刻后停止呕吐。这是因为乳食无节制，脾气虚弱不能承受，迅速将空奶瓶让婴儿尝试，乳房通畅呕吐停止为最佳。
呕吐症状既然分辩明白，治疗方法尤其贵在精微。冷吐用理中汤最合适，热吐用五苓散去掉桂枝。积吐用九转灵应丹，攻下后用枳术丸调理，伤乳而呕吐的药方奇特，三棱散最为有效。
呕吐且乳食无法纳入，即使是汤药也难以品尝，这叫阴盛格拒孤阳，当时的医生却没有主张。人参、白术、煨姜、熟附子，乌梅、童便尤其好，猪胆一同放入慢慢斟酌，这种方法效果应验如影随形。
对于各种呕吐药物都无法纳入的情况，我有绝胜奇的方子，定吐饮子妙不可言。半夏、官桂两样药，生姜特别适宜多用，甘草少用为好，根据方子制造水煎服用，仍然以生姜为上。
第一等是蛔虫吐出，这是因为蛔虫多涉及厥阴经，乌梅丸效果如神，一服后蛔虫安定呕吐停止。又有咳嗽伴随呕吐的，化痰顺气必须明辨，如果是普通呕吐只用胃苓丸，汤剂用生姜作为引经药。
呕吐不止的症状，明确说给医生听，如果服用正规药物都无灵验，更加烦躁乱闷。呕吐只是不停止；眼球上翻必须警惕危险，头往上仰魂魄似要飞走，只好安排后事。
再附带恶心这一症状，有痰、有热、有虚三种情况，生姜这三种情况都通用。药物应当随症状分别处理。如果是胃中有热，二陈汤加上茯苓、黄连，用姜汁炒过后共同煎煮，各用一钱最灵验。
This medicine has a neutral nature and can be used for both cold and heat syndromes.
Chenpi (aged tangerine peel), Banxia (Pinellia Rhizoma processed with ginger juice seven times), Baifuling (Poria Cocos with wood), Gancao (Licorice Root). Use three slices of Shengjiang (Fresh Ginger) as a guiding herb, decoct in one cup of water and take before meals. If vomiting is severe, add Baizhu (Atractylodes Macrocephala Rhizome) and Wei Ganjiang (Baked Dried Ginger); these two are essential herbs for treating vomiting. For vomiting accompanied by heat signs, add Wei Ganjiang (Baked Dried Ginger) and Chao Huanglian (Stir-fried Coptis Rhizome). If caused by food stagnation, add Shenqu (Medicated Leaven), Chao Maiya (Stir-fried Hordeum Sprout), Sharen (Amomum Fruit), Xiangfuzi (Cyperi Rhizoma), and Shanzha (Crataegus Fruit). These five are essential herbs for resolving food stagnation.
The ancestral method for treating vomiting uses only Weiling Wan (Weiling Pill), swallowed with a decoction of Wei Ganjiang (Baked Dried Ginger), regardless of cold or heat syndromes.
If vomiting persists, medication is ineffective, and restlessness develops, it is incurable. If vomiting persists and the eyes roll upward, it is incurable. If the head tilts backward, it is incurable.
Xijiang Yue:
The causes of vomiting are diverse; practitioners must distinguish the root cause. "Ou" (retching) involves sound and matter occurring simultaneously; "Tu" (vomiting) involves matter without sound. There is also the condition of sound without matter, named "Yue" (dry heaving/hiccup-like retching), which requires differentiated syndrome treatment and separate medication administration, sometimes making it difficult to intervene.
Cold Vomiting: Milk and food are not digested, abdominal distension and panting occur incessantly, the face is pale, eyes are dull, there is much sighing, and vomitus contains undigested food and clear fluid. This is due to wind-cold invading the stomach or damage from consuming raw/cold foods. Or it is due to retained milk stagnating in the stomach causing deficiency, leading to inability to retain milk/food and subsequent vomiting.
Heat Vomiting: Lips are red, face is flushed, although milk/food enters and is digested, the vomitus is yellow, the whole body feels hot, there is excessive thirst, and irritability. This is due to summer-heat in the stomach or damage from consuming hot-natured foods, causing stomach qi to become disharmonious due to heat, leading to rebellious qi and vomiting.
How to distinguish Food Stagnation Vomiting? Eyelids are puffy, complexion is slightly yellow, feet are cold while the abdomen is abnormally hot, symptoms are lighter during the day and heavier at night, resembling bewitchment. This is due to retained cold stagnating in the spleen and stomach, resulting in vomiting of yellow acidic fluids or foul-smelling sour regurgitation, indicating injury from retained food.
For infants vomiting due to overfeeding milk, the signs and symptoms require careful observation. Vomiting occurs immediately after feeding or stops after a short pause. This is due to unregulated milk intake and weak spleen qi unable to handle it. Quickly offer an empty bottle for the infant to suckle; if vomiting stops upon clearing the breast channel, it is optimal.
Since vomiting syndromes are clearly distinguished, treatment methods must be precise. For Cold Vomiting, Lizhong Tang (Regulate the Middle Decoction) is most suitable. For Heat Vomiting, Wuling San (Five-Ling Powder) with Gui Zhi (Cinnamon Twig) removed. For Food Stagnation Vomiting, Jiuzhuan Lingying Dan (Nine-Turn Efficacious Pill); after purging, regulate with Zhizhu Wan (Immature Bitter Orange and Atractylodes Pill). For vomiting due to milk injury, the unique prescription is Sanleng San (Sanleng Powder), which is most effective.
When vomiting prevents retention of milk and food, even herbal decoctions cannot be tolerated; this is termed Yin excess repelling isolated Yang. Contemporary physicians often lack direction. Renshen (Ginseng Root), Baizhu (Atractylodes Macrocephala Rhizome), Wei Jiang (Baked Ginger), Shu Fuzi (Prepared Aconite Lateral Root), Wu Mei (Mume Fruit), and Tongbian (Child's Urine) are excellent. Adding Zhu Dan (Pig Gallbladder) and processing slowly yields effects as immediate as shadow and echo.
For cases where all anti-emetic drugs are rejected, I have a superior miraculous formula, Dingtu Yinzi (Vomiting-Stabilizing Drink), which is extraordinarily effective. Banxia (Pinellia Rhizoma) and Guanzi Gui (Cassia Bark) are the two main ingredients; Shengjiang (Fresh Ginger) should be used generously, while Gancao (Licorice Root) should be used sparingly. Prepare according to the formula, decoct in water, and use Shengjiang (Fresh Ginger) as the best adjunct.
The first category is vomiting of roundworms, indicating many worms involving the Jueyin (Terminal Yin) channel; Wumei Wan (Mume Pill) is efficacious as if divine, calming worms and stopping vomiting with one dose. For coughing accompanied by vomiting, resolve phlegm and smooth qi must be clearly understood. For ordinary vomiting, simply use Weiling Wan (Weiling Pill), with Shengjiang (Fresh Ginger) as the guiding herb in the decoction.
Regarding persistent vomiting, explain clearly to the physician: if standard medicines fail and irritability/confusion worsens, and vomiting continues unabated with eyes rolling upward, the situation is critical. If the head tilts back as if the soul is flying away, prepare for the end.
Additionally, regarding nausea: it may be due to phlegm, heat, or deficiency. Shengjiang (Fresh Ginger) is universally applicable for these three conditions. Medications should be prescribed according to the specific syndrome. If there is heat in the stomach, add Fuling (Poria Cocos) and Huanglian (Coptis Rhizoma) to Erchen Tang (Two-Aged Decoction), stir-fry with ginger juice, decoct together, using 3 grams (one qian) of each for best results.
