许仁则，疗呕吐病有两种，一者积热在胃，呕逆不下食，一者积冷在胃，亦呕逆不下食
，二事正反，须细察之，必其食饮寝处将息伤热，又素无冷病，年壮力强，肤肉充满，此则
是积热在胃，致此呕逆，如将息食饮寝处不热，又素有冷病，年衰力弱，肤肉瘦悴，此则积
冷在胄，生此呕逆，若是积冷，呕逆经久，急须救之，不尔，甚成反胃病，积热在胃，呕逆

许仁则治疗呕吐病有两种情况：一种是胃中有积热，导致呕吐逆气、无法进食；另一种是胃中有积冷，同样出现呕吐逆气、无法进食。这两种情况性质相反，必须仔细辨别。如果是因饮食起居调摄不当而受热，且平时没有寒性疾病，年纪轻体力强，肌肉丰满，这属于胃中积热引起的呕吐逆气。如果饮食起居调摄未受热，且平时素有寒性疾病，年老体弱，肌肉消瘦憔悴，这属于胃中积冷引起的呕吐逆气。如果是胃中积冷，呕吐逆气经久不愈，急需救治，否则很容易发展成反胃病（一种以食物和痰涎从胃中上逆而出的疾病）。
对于胃中积热引起的呕吐逆气、无法进食，适宜使用生芦根五味饮，服用方法如下：
生芦根（切细一升）、生麦门冬（一升，去心）、青竹茹（一升）、生姜汁（五合）、茯苓（五两）。
以上药物切碎，用水八升，煮取二升半，滤去药渣，加入竹沥六大合，搅拌均匀，分三次服用。两次服药间隔时间相当于人行走十里路所需的时间，然后再服下一剂。忌食醋及酸性食物。
另外，依照前面生芦根等五味药制成的汤剂服用虽然有效，但如果不能完全除根，适宜使用茯苓等五味丸，服用方法如下：
茯苓（五两）、人参（三两）、麦门冬（一升，去心）、生姜（切成屑六两）、青竹茹（一升）。
以上药物捣碎过筛，用蜂蜜调和制成丸剂，用煎好的芦根汤送服。初次服用十五丸，每日两次，逐渐增加至三十丸，丸剂大小如梧桐子。忌食醋及酸性食物。
又有胃中积冷引起的呕吐逆气、无法进食，适宜使用半夏等二味丸，服用方法如下：
半夏（一升，经炮制）、小麦面（一升）。
将半夏捣碎成散剂，用水调和小麦面制成如弹子大小的丸剂，用水煮熟，面条熟透即表示药成。初次吞服四五丸，每日两次，逐渐增加至十四五丸，现煮现服。服用后感觉病情减轻，如果想再次配合服用此药也很好。忌食羊肉和饴糖。（急救时用法相同）
另外，依照前面的半夏等二味丸，虽然感觉病情逐渐减轻，但病根未除。如果想多服用前面的丸剂，又担心有毒性的药物不宜久服；如果不吃药，又恐怕病情蔓延加重。适宜使用人参等七味丸，服用方法如下：
人参（五两）、白术（五两）、生姜屑（八两）、浓朴（四两，炙烤）、细辛（四两）、橘皮（三两）、桂心（二两）。
以上药物捣碎过筛成粉末，用蜂蜜调和制成丸剂，大小如梧桐子。用汤水送服。初次服用十丸，每日两次，逐渐增加至二十丸。也可以与前方的半夏丸交替服用。忌食桃李、雀肉、生葱、生菜。（吴升的方子与此相同，均出自第一卷中）
Xu Renze treated vomiting disease with two types: one is accumulation of heat in the Stomach, causing retching and inability to eat; the other is accumulation of cold in the Stomach, also causing retching and inability to eat. These two conditions are opposite in nature and must be carefully distinguished. If the cause is injury from improper regulation of diet, sleep, and living habits leading to heat, and there is no history of cold diseases, the person is young and strong with full flesh, this is accumulation of heat in the Stomach causing such retching. If the regulation of diet, sleep, and living habits did not involve heat, and there is a history of cold diseases, the person is old and weak with emaciated flesh, this is accumulation of cold in the Stomach causing such retching. If it is accumulation of cold, and retching has persisted for a long time, urgent rescue is required; otherwise, it may easily develop into Fan Wei Bing (Rebellious Stomach Disease, a condition characterized by regurgitation of food and phlegm).
For vomiting and retching due to accumulation of heat in the Stomach with inability to eat, Sheng Lugen Wuwei Yin (Raw Reed Root Five-Ingredient Decoction) is suitable. The prescription is as follows:
Sheng Lugen (Cut, 1 sheng), Sheng Maimendong (1 sheng, remove heart), Qing Zhuru (Green Bamboo Shavings, 1 sheng), Shengjiang Zhi (Fresh Ginger Juice, 5 he), Fuling (Poria, 5 liang).
The above herbs are cut, boiled in 8 sheng of water until reduced to 2.5 sheng, strained, then Zhu Li (Bamboo Sap, 6 large he) is added and mixed well. Divide into three doses. Take the next dose after an interval equivalent to the time it takes a person to walk ten li. Avoid vinegar and acidic foods.
Furthermore, although taking the decoction made from the previous five ingredients including Sheng Lugen is effective, if it fails to completely eradicate the root cause, Fuling Wuwei Wan (Poria Five-Ingredient Pill) is suitable. The prescription is as follows:
Fuling (Poria, 5 liang), Renshen (Ginseng, 3 liang), Maimendong (Ophiopogon Tuber, 1 sheng, remove heart), Shengjiang (Fresh Ginger, 6 liang, shredded), Qing Zhuru (Green Bamboo Shavings, 1 sheng).
The above herbs are crushed and sifted, mixed with honey to form pills, and taken down with a decoction of Lugen. Start with 15 pills, twice daily, gradually increasing to 30 pills. The pills should be the size of Sophora seeds. Avoid vinegar and acidic foods.
Another case involves vomiting and retching due to accumulation of cold in the Stomach with inability to eat. Banxia Erwei Wan (Pinellia Two-Ingredient Pill) is suitable. The prescription is as follows:
Banxia (Pinellia Rhizome, 1 sheng, processed), Xiaomai Mian (Wheat Flour, 1 sheng).
Crush Banxia into powder, mix with water and wheat flour to form pills the size of bullet seeds. Boil in water until the flour is cooked, indicating the medicine is ready. Swallow 4-5 pills initially, twice daily, gradually increasing to 14-15 pills. Cook and take immediately. If symptoms improve upon taking this, continuing to take it is also good. Avoid mutton and maltose sugar. (Same for emergency use).
Furthermore, regarding the previous Banxia Erwei Wan, although symptoms gradually diminish, the root cause remains. If one wishes to take more of the previous pill but fears that potentially toxic drugs should not be taken for a long time; or if one does not wish to take medicine but fears the disease will spread, Ren Shen Qiwu Wan (Ginseng Seven-Ingredient Pill) is suitable. The prescription is as follows:
Renshen (Ginseng, 5 liang), Baizhu (Atractylodes Macrocephala Rhizome, 5 liang), Shengjiang Xie (Fresh Ginger Shreds, 8 liang), Houpo (Magnolia Bark, 4 liang, stir-fried), Xixin (Asarum, 4 liang), Chenpi (Citrus Reticulata Peel, 3 liang), Guixin (Cinnamon Twig Heart, 2 liang).
The above herbs are crushed and sifted into powder, mixed with honey to form pills the size of Sophora seeds. Take down with water. Start with 10 pills, twice daily, gradually increasing to 20 pills. It is also acceptable to alternate with the previous Banxia Wan. Avoid peaches, plums, sparrow meat, raw green onions, and raw vegetables. (Wu Sheng's formula is the same, both appearing in Volume I).
