有声有物为呕，有物无声为吐。其证有寒有热有伤食。然寒热皆因于伤食，总属胃经。
复有溢乳 乳呕哕，皆与呕吐相似，而不可以呕吐治之。更有寒热拒隔之证，又有虫痛而
吐者，症治俱详载《幼幼集成》。凡治小儿呕吐，宜减少其乳食。凡呕吐多渴，不可与之茶水
，水入复吐，必须忍渴一二时，而后以米汤与之，吐自止矣。
将粪蛆清洗至极干净，晒干后微炒成粉末，用量三钱；毛褐衣（即蝉蜕）烧成灰，用量一钱半；两者共同研磨均匀，频繁吹入患儿口腔内，疗效显著。
另一个方子，治疗牙疳和鼻疳：取人中白（人尿自然沉淀物），用量一钱半；毛褐灰、枯矾各一钱，研成细末。患处湿润者直接干掺药粉，干燥者用香油润湿后再涂抹。
口疳导致口腔破烂：取人中白煅过，浓黄柏蜜炙至焦黑，两者等分，少量加入冰片，共同研成粉末。先用盐茶水漱口，然后将药末涂抹于患处。
走马牙疳以及齿龈腐烂、发黑、有恶臭者：取溺壶内多年的积垢，煅红，用量一两；儿茶五钱；黄柏、薄荷、青黛各一钱；冰片三分。共同研成细末。先用温水漱口，然后将药粉吹敷在疳疮上，每日六七次。吹药时涎水从口中流出者为吉兆；若涎水收束在口腔内，说明毒邪深入体内，难以治愈。
治疗疳蚀烂坏口鼻、痛苦欲死者：取海中紫贝子，俗称砑螺，用炭火煅烧后研成粉末，用腊月猪油调和涂抹。
治疗牙疳溃烂导致穿唇破舌：同时治疗口疮。川黄连五分，胆矾、儿茶各一钱半，共同研成细末涂抹患处。
用干蟾蜍烧成灰三钱，黄连二钱，青黛一钱，麝香五厘，共同研成粉末。先用甘草汤清洗患处，然后涂抹药物，效果奇妙。
眼睑肿胀，腹部胀满，痢疾颜色无常：取新鲜羊屎一升，水一升，浸泡一夜，次日清晨绞取汁液，一次性服用，中午再进食。病情极危重者，服用三次即可痊愈。
有声有物排出称为呕，有物无声排出称为吐。呕吐的证候有寒证、热证和伤食证。然而寒证和热证都因伤食引起，总归属于胃经。另外还有溢乳、噎乳、呕哕等症状，都与呕吐相似，但不能按照呕吐来治疗。更有寒热格拒之证，以及虫痛引起的呕吐，症状和治疗均详细记载在《幼幼集成》中。凡是治疗小儿呕吐，应当减少其乳汁和食物的摄入。凡呕吐多伴有口渴，不可给予茶水，因为水入后会再次引发呕吐，必须忍耐口渴一两个小时，然后用米汤喂服，呕吐自然停止。
Clean earthworms (or maggots, contextually likely referring to a specific larval preparation or typo for another substance, but literally "fecal maggots") thoroughly with water, dry them in the sun, stir-fry lightly until powdered. Dosage: 3 qian; burn cicada slough (Maohe Yi) into ash. Dosage: 1.5 qian. Grind both uniformly together. Frequently insufflate the powder into the mouth. Effective.
Another prescription for treating dental gan and nasal gan: Renzhongbai (Calcined Human Urine Deposit), 1.5 qian; Maohe hui (Cicada Slough Ash) and Kufan (Alum) each 1 qian. Grind into fine powder. For moist lesions, apply dry powder directly; for dry lesions, moisten with sesame oil before application.
For oral gan causing ulceration and breakdown: Calcine Renzhongbai (Calcined Human Urine Deposit). Honey-roast Huangbo (Phellodendron Bark) until charred black. Use equal parts of both, add a small amount of Bingpian (Borneol). Grind into powder. After rinsing the mouth with salted tea water, apply the powder to the affected area.
For Zouma yagan (Rapidly progressing dental gan) characterized by gingival rot, blackening, and foul odor: Use accumulated scale from chamber pots over many years. Calcine until red-hot. Dosage: 1 liang. Ercha (Tectoridin) 5 qian; Huangbo (Phellodendron Bark), Bohe (Mint), Qingdai (Indigo Naturalis) each 1 qian; Bingpian (Borneol) 3 fen. Grind into fine powder. Rinse mouth with warm water first, then insufflate the medicine onto the gan lesion. Apply 6-7 times daily. If saliva flows out during insufflation, it is a auspicious sign indicating toxin expulsion. If saliva remains inside the mouth, the toxin has penetrated inward, which is difficult to treat.
To treat gan erosion destroying the mouth and nose, causing extreme suffering: Take Haizhong zibeizi (Purple Shell from the Sea), commonly known as Yaluo. Calcine in charcoal fire, grind into powder. Mix with lard from the twelfth lunar month for topical application.
To treat dental gan ulceration leading to perforated lips and broken tongue: Also treats oral ulcers. Chuanhuanglian (Coptis Rhizome) 5 fen; Danfan (Chalcanthite) and Ercha (Tectoridin) each 1.5 qian. Grind into fine powder and apply topically.
Burn dried Bufo bufo gargarizans (Toad skin/body) into ash: 3 qian; Huanglian (Coptis Rhizome): 2 qian; Qingdai (Indigo Naturalis): 1 qian; Shexiang (Musk): 5 li. Grind into powder. First rinse with Licorice Decoction (Gancao Tang), then apply. Excellent effect.
For swollen eyelids, abdominal distension, and dysentery with variable stool color: Take one sheng of fresh sheep dung. Add one sheng of water. Soak overnight. Squeeze out the juice early next morning. Administer in one dose. Eat only at noon. For extremely critical cases, three doses will result in recovery.
Vomiting with sound and matter expelled is called Ou (Vomit); expelling matter without sound is called Tu (Regurgitate/Emit). These syndromes can be Cold, Heat, or Food Stagnation. However, both Cold and Heat syndromes often stem from Food Stagnation, ultimately belonging to the Stomach Meridian. Additionally, symptoms such as milk overflow, choking on milk, and hiccuping resemble vomiting but should not be treated as vomiting. There are also syndromes of Cold-Heat rejection/blockage, and vomiting caused by worm pain. Symptoms and treatments are detailed in *Youyou Jicheng* (Complete Works on Pediatrics). In treating pediatric vomiting, reduce milk and food intake. When vomiting is accompanied by thirst, do not give tea or water, as ingesting water may trigger further vomiting. The child must endure thirst for one to two hours, then administer rice soup, after which vomiting will cease naturally.
