甲、概况
饮食入胃而上泛回出者谓之吐，吐又有呕吐哕三者之别。呕
者，吐之有声有物者；吐者，吐之无声有物者；哕者，吐之有声无物者。呕与吐常相连属，往往初起为吐，吐
将尽则继之以呕者。其证有虚有实，而哕则常由于虚，纵或挟实，不过挟痰挟火，虚多而实少者也。进而至于
无声无物之干恶心，为胃腑气血两伤，小儿难治之证也。今先言呕，食入即呕，刻不能容，其势疾，其声壮，
呕黄水而味酸苦者热也。盖胃中有火，不能容食，驱逐上行，非倾吐不完不止，因动肝火而气逆犯胃者亦如之。
食入能容，渐泛而作呕，其势缓，其声壮者，虚实参半也。盖胃虚谷气不行，火复乘之上逆有以致之。水到食
管即呕，或呕而由胃底肠中翻出者虚也。盖到咽即呕为气虚不能载物，由肠胃翻出而呕，为脾胃虚弱不能运
化，有以致之。此呕之一类也。次再言吐，吐而食物不化，吐而酸臭触鼻者，是为伤食；吐而出水饮痰
涎，是为停饮蓄痰；吐而面唇青白，清涎夹乳，是为感寒；吐而直冒酸臭，烦怒多啼，是为挟热。此吐之一
类也。然呕吐多相连属，故其因可互相参看也。至于呕吐之起源，多由小儿乳食不化，或露腹受寒，或触秽
感热所致。其有突然呕吐，一起即困倦自汗者，则由胃气久伤，病因早种所致。久吐不愈，若不由于胃
气耗伤，必因痰湿水饮，蓄滞不行，阻其饮食消化之路，郁蒸所致。哕之起源，虽有气滞、痰滞、饮滞、食滞
数因，而其本多由胃虚气弱，不能上达所致。干恶心之起源，多由呕哕经久，胃气益伤所致。乳食亏缺，大病
之后，亦均足致此。总之，胃为后天之本，水谷之海，久病不愈，必至养生之源，竭绝莫挽，固在心
存保赤者之未雨绸缪也。
乙、治法
呕之初起，宜用小半夏汤治之。暴呕挟有胃火者，酌加黄连；挟有痰气者，酌加竹茹；呕而口渴者，酌
加芦根；呕出酸水苦水挟有肝火者，酌加左金丸；呕出清水而口渴，水入又呕者，
酌加五苓散；呕而兼吐食者，酌加陈皮、神曲之属；因虫扰而呕
者，酌加黄连、川椒之属，或用乌梅丸以安之；呕之虚实参半者，其势虽缓，然常时止时作，宜补胃调中，用
大半夏汤和之；胃阳虚而浊阴上逆者，先用逍遥散疏其郁，继用人参、白术、山药之属以补之；脾胃虚弱，不
能运化，致水到咽辄呕，或由胃底肠中倾翻而出，宜六君子汤加砂仁、炮姜或加荜澄茄、肉桂之属；
肝阴胃液，两皆虚耗，服热药呕虽暂止而愈发愈剧，舌苔剥者，宜滋液养胃，熄风镇逆，用六味地黄丸加扁
钗斛、石决明、滁菊、西洋参之属。吐之初起，常由伤食，治宜消积行滞。吐而食
物不化者，宜二陈汤加山楂（消肉积）、麦芽（消米麦积）、神曲（消痰食胶结之积）、枳实、川朴（消痰湿
胶结之积）之属；吐而夹水夹痰者，宜平胃散加半夏、茯苓之属。凡感寒而吐，有腹痛吐清涎等证象者，治
宜祛寒化积，用紫苏、煨姜、橘红、白豆蔻、半夏、木香、白术之类。凡挟热而吐，有恶食、烦怒等证
象者，治宜清热降气，用黄连、生姜、神曲、枳实、青皮、大黄之类。凡触秽而吐，有昏闷、口臭等证象者，
治宜芳香化浊，用藿香、佩兰、浓朴、白芷、菖蒲、神曲、香豆豉之类（夏月胃气疲弱者多见之）。突然呕
吐，困倦自汗，胃气暴伤者，治宜附子理中汤多加白术，此为吐证之重者，宜急救勿缓。至于常年呕吐，
按时而发，谓之反胃，在乳哺之小儿为绝少，童年或间有之。治法大致分寒热虚三种∶寒反胃者呕青手足冷，
宜二陈汤加丁香、附子、干姜、肉桂之属；热反胃者呕酸苦，面红手足热，宜二陈汤加黄芩、黄连之属；虚
反胃者，呕宿食不化，脉软无力，宜四君子汤或四物汤之属，而随证应变，又可合呕吐之治法以参看者
也。哕之治法∶声高有力而连属者，属热，可下；声低力怯而不上达者，属寒，宜温。通治之法，总宜调其
胃气，若偶被冷风所吹而作呃逆者，此属于外因，稍饮热汤，气定自愈，可不必服药。干恶心之治法，宜用
橘红煎服，入姜汁、白蜜，细细呷之，以滋润之。胃热者加川连、竹茹；胃寒者加炮姜；胃虚者加人
参；气逆者加吴萸。总之，凡治呕吐，当其初起泛恶之时，宜引而吐之，以去其滞，吐后方用药安之，则胃
气不伤。久呕不止，必加镇重之药以坠之。中气久虚，必借谷食以和之，或饴糖、白蜜以润之，忌用有油之物
如桃仁、杏仁、栝蒌、莱菔子、山栀（其有不得不用者亦在所不禁）之属。此皆不可不知也。

甲、概况
饮食进入胃中而上泛吐出，称为“吐”。吐又分为呕、吐、哕三种区别。所谓“呕”，是指呕吐时既有声音又有实物吐出；所谓“吐”，是指呕吐时没有声音但有实物吐出；所谓“哕”，是指呕吐时有声音但没有实物吐出。“呕”与“吐”常常相互关联，往往起初表现为吐，吐将结束时随即转为呕。其证候有虚证和实证之分，而“哕”多由于虚证引起，即使夹杂实证，也不过是夹杂痰湿或火热，总体上是虚多实少。进一步发展到无声无物的干恶心，属于胃腑气血两伤，是小儿难以治疗的证候。现在先讲“呕”：食物吃下去立即呕吐，片刻不能容纳，病势急迫，声音洪亮，呕吐黄水且味道酸苦的，属于热证。这是因为胃中有火，不能容纳食物，迫使食物向上驱逐，不倾吐干净不止息，因肝火动扰导致气逆犯胃的情况也是如此。食物吃下后能暂时容纳，逐渐泛起并发生呕吐，病势缓慢，但声音洪亮的，属于虚实参半的证候。这是因为胃气虚弱，谷气运行不畅，火热再次乘虚上逆所致。水喝到食管就呕吐，或者呕吐物从胃底、肠中翻涌而出的，属于虚证。这是因为食物到达咽喉就呕吐，是气虚不能承载食物；从肠胃翻出而呕吐，是脾胃虚弱不能运化所致。这是“呕”的一类情况。接着再讲“吐”：呕吐出的食物不消化，气味酸臭刺鼻的，这是伤食（饮食积滞）；呕吐出水液、痰涎的，这是停饮蓄痰（水饮停滞、痰浊内聚）；呕吐时面色嘴唇青白，清稀涎沫夹杂乳汁的，这是感寒（感受寒邪）；呕吐直冒酸臭味，烦躁易怒、多啼哭的，这是挟热（兼夹热邪）。这是“吐”的一类情况。然而呕吐多相互关联，所以病因可以互相参考。至于呕吐的起源，多由小儿乳食不消化，或腹部受凉，或接触秽浊之气、感受热邪所致。如果有突然呕吐，一起病就感到困倦、自汗的，则是由于胃气长期受损，病因早已潜伏所致。久吐不愈，如果不是因为胃气耗伤，必定是因为痰湿水饮，蓄积停滞不行，阻碍了饮食消化的道路，郁结蒸腾所致。“哕”的起源，虽然有气滞、痰滞、饮滞、食滞几种原因，但其根本多由胃虚气弱，不能上行所致。干恶心的起源，多由呕、哕经久不愈，胃气更加受伤所致。乳食缺乏、大病之后，也都足以导致这种情况。总之，胃为后天之本，是水谷之海，久病不愈，必然导致养生之源枯竭而无法挽回，这确实需要儿科医生在未雨绸缪地加以保护。
乙、治法
“呕”的初起阶段，适宜用小半夏汤治疗。暴发性呕吐夹杂胃火的，酌情加入黄连；夹杂痰气的，酌情加入竹茹；呕吐伴有口渴的，酌情加入芦根；呕吐酸水苦水并夹杂肝火的，酌情加入左金丸；呕吐清水且口渴，喝水后又呕吐的，酌情加入五苓散；呕吐兼有吐食的，酌情加入陈皮、神曲等药物；因虫扰而导致呕吐的，酌情加入黄连、川椒等药物，或使用乌梅丸来安蛔止痛；呕吐虚实参半的，虽然病势缓慢，但经常时好时坏，应当补胃调中，使用大半夏汤调和；胃阳虚衰而浊阴之气上逆的，先用逍遥散疏解郁结，继用人参、白术、山药等药物以补益；脾胃虚弱，不能运化，导致水液到达咽喉即呕吐，或由胃底肠中倾翻而出，适宜六君子汤加砂仁、炮姜，或加荜澄茄、肉桂等药物；肝阴与胃液两皆虚耗，服用热药后呕吐虽暂时停止但愈发剧烈，舌苔剥落的，应当滋阴润液、养胃熄风镇逆，使用六味地黄丸加扁钗斛、石决明、滁菊、西洋参等药物。“吐”的初起阶段，常由伤食引起，治疗应当消积行滞。呕吐食物不消化的，适宜二陈汤加山楂（消除肉食积滞）、麦芽（消除米麦积滞）、神曲（消除痰食胶结之积）、枳实、厚朴（消除痰湿胶结之积）等药物；呕吐夹杂水湿痰浊的，适宜平胃散加半夏、茯苓等药物。凡是感受寒邪而呕吐，有腹痛、吐清涎等症状表现的，治疗应当祛寒化积，使用紫苏、煨姜、橘红、白豆蔻、半夏、木香、白术等类药物。凡是兼夹热邪而呕吐，有厌食、烦躁易怒等症状表现的，治疗应当清热降气，使用黄连、生姜、神曲、枳实、青皮、大黄等类药物。凡是接触秽浊之气而呕吐，有昏闷、口臭等症状表现的，治疗应当芳香化浊，使用藿香、佩兰、浓朴、白芷、菖蒲、神曲、香豆豉等类药物（夏季胃气疲弱者多见此症）。突然呕吐，困倦自汗，胃气暴伤的，治疗应当用附子理中汤多加白术，这是呕吐证中的重症，应当急救不可迟缓。至于常年呕吐，按时发作，称为反胃，在哺乳期的婴儿中极少见，童年时期偶尔会有。治疗方法大致分为寒、热、虚三种：寒性反胃者，呕吐青色液体，手足冰冷，适宜二陈汤加丁香、附子、干姜、肉桂等药物；热性反胃者，呕吐酸苦液体，面红手足发热，适宜二陈汤加黄芩、黄连等药物；虚性反胃者，呕吐未消化的宿食，脉象软弱无力，适宜四君子汤或四物汤等药物，并根据证候变化灵活调整，又可以结合呕吐的治疗方法参考应用。“哕”的治疗方法：声音高亢有力且连续的，属于热证，可以用攻下法；声音低微力怯且气不上达的，属于寒证，应当温补。通用治法，总宜调理胃气，如果是偶然被冷风吹拂而引发呃逆的，这属于外因，稍喝热汤，气定即可自愈，不必服药。干恶心的治疗方法，适宜用橘红煎服，加入姜汁、白蜜，细细呷饮，以滋润胃气。胃热者加川连、竹茹；胃寒者加炮姜；胃虚者加人参；气逆者加吴茱萸。总之，凡是治疗呕吐，在其初起泛恶之时，适宜引导其吐出，以去除积滞，吐完后再用药安抚，则胃气不受损伤。久呕不止，必须加入镇重药物以降逆。中气长期虚弱，必须借助谷食来调和，或用饴糖、白蜜来滋润，忌用含有油脂的物品如桃仁、杏仁、栝蒌、莱菔子、山栀等（如有不得不用者，也在所不禁）。这些道理都是不可不知道的。

A. Overview
When food enters the stomach and regurgitates upwards, it is termed "Tu" (Vomiting). Tu is further differentiated into three types: Ou (Retching/Vomiting with sound), Tu (Vomiting without sound), and Yue (Hiccups/Retching with sound but no substance). "Ou" refers to vomiting accompanied by both sound and expelled matter; "Tu" refers to vomiting with expelled matter but no sound; "Yue" refers to retching or hiccups with sound but no expelled matter. "Ou" and "Tu" are often interconnected; typically, the condition begins as "Tu," and as it subsides, it transitions into "Ou." These syndromes can be either Deficient (Xu) or Excess (Shi). However, "Yue" usually stems from Deficiency; even when complicated by Excess patterns, it is merely due to Phlegm-Dampness or Fire, generally characterized by more Deficiency than Excess. Progressing to dry nausea without sound or substance indicates injury to both Qi and Blood of the Stomach organ, a difficult-to-treat syndrome in children.
First, let us discuss "Ou": Immediate vomiting after eating, where food cannot be retained for even a moment, indicates an urgent condition with loud sounds. Vomiting yellow fluid with a sour and bitter taste signifies Heat. This occurs because Fire in the Stomach cannot accommodate food, forcing it upward until fully expelled. Similar mechanisms apply when Liver Fire moves, causing Qi rebellion invading the Stomach. If food is temporarily retained but gradually rises to cause vomiting, with a slow progression but loud sounds, this represents a mixed pattern of Deficiency and Excess. This results from weak Stomach Qi failing to transport Grain Qi, allowing Fire to ascend and rebel. Vomiting immediately upon water reaching the esophagus, or vomitus surging up from the bottom of the stomach or intestines, indicates Deficiency. Vomiting at the throat suggests Qi Deficiency unable to carry substances; vomiting from the stomach/intestine base suggests Spleen-Stomach weakness failing to transform and transport. This constitutes one category of "Ou."
Next, we discuss "Tu": Vomiting undigested food with a pungent, sour-rotten odor indicates Food Retention (Shang Shi). Vomiting clear fluids, phlegm, and saliva indicates Fluid Retention and Phlegm Accumulation (Ting Yin Xu Tan). Vomiting with cyanotic pale lips and face, mixed with clear saliva and milk, indicates Cold Invasion (Gan Han). Vomiting with direct emission of sour-rotten odors, accompanied by irritability, anger, and excessive crying, indicates Heat Complication (Xie Re). This constitutes one category of "Tu." Since "Ou" and "Tu" are often linked, their etiologies can be cross-referenced.
The origins of vomiting and retching mostly stem from infants' inability to digest breast milk or food, exposure of the abdomen to cold, or contact with turbid pathogens and Heat. Sudden vomiting accompanied by immediate fatigue and spontaneous sweating indicates long-term damage to Stomach Qi, where the pathogenic factor was latent from the beginning. Chronic vomiting that fails to resolve, if not due to Stomach Qi exhaustion, must be caused by Phlegm-Dampness and Fluids accumulating and stagnating, obstructing digestion and causing郁蒸 (stagnant steaming). The origin of "Yue," although involving Qi stagnation, Phlegm stagnation, Fluid stagnation, or Food stagnation, fundamentally stems from weak Stomach Qi and deficiency, preventing Qi from ascending. Dry nausea originates from prolonged "Ou" and "Yue" further injuring Stomach Qi, or from nutritional deficiency and post-major illness states. In summary, the Stomach is the Root of Post-Heaven and the Sea of Water and Grain. Prolonged illness leads to the exhaustion of the source of nourishment, which is irreversible. Therefore, pediatricians must take preventive measures (Wei Yu Chou Mou) to protect the child.
B. Treatment Methods
For early-stage "Ou," Xiao Ban Xia Tang (Minor Pinellia Decoction) is appropriate. For acute vomiting complicated by Stomach Fire, add Huang Lian (Coptis Rhizome); for Phlegm-Qi complication, add Zhu Ru (Bamboo Shavings); for vomiting with thirst, add Lu Gen (Reed Rhizome); for vomiting sour/bitter fluids with Liver Fire, add Zuo Jin Wan (Left Metal Pill); for vomiting clear fluid with thirst, where drinking water triggers immediate vomiting, add Wu Ling San (Five-Ingredient Powder with Poria). For vomiting accompanied by food expulsion, add Chen Pi (Tangerine Peel) and Shen Qu (Medicated Leaven). For vomiting caused by intestinal parasites, add Huang Lian and Chuan Jiao (Sichuan Pepper), or use Wu Mei Wan (Mume Pill) to calm the parasites. For mixed Deficiency-Excess "Ou," which is slow but intermittent, tonify the Stomach and harmonize the Middle using Da Ban Xia Tang (Major Pinellia Decoction). For Stomach Yang Deficiency with Turbid Yin rebelling upward, first use Xiao Yao San (Free and Easy Wanderer Powder) to soothe depression, followed by Ren Shen (Ginseng), Bai Zhu (Atractylodes Macrocephala Rhizome), and Shan Yao (Dioscorea Rhizome) to tonify. For Spleen-Stomach weakness failing to transform, causing vomiting upon water reaching the throat or surging from the stomach base, use Liu Jun Zi Tang (Six-Gentleman Decoction) plus Sha Ren (Amomum Fruit), Pao Jiang (Prepared Ginger), Bi Cheng Qie (Long Pepper Fruit), or Rou Gui (Cinnamon Bark). For simultaneous depletion of Liver Yin and Stomach Fluids, where hot medicines temporarily stop vomiting but worsen the condition, accompanied by peeled tongue coating, nourish fluids, tonify the Stomach, extinguish Wind, and suppress rebellion using Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) plus Bian Chai Hu (or similar orchid rhizomes), Shi Jue Ming (Abalone Shell), Chu Ju (Chrysanthemum), and Xi Yang Shen (American Ginseng).
For early-stage "Tu," often caused by Food Retention, treatment should focus on resolving accumulation and promoting stagnation resolution. For vomiting undigested food, use Er Chen Tang (Two-Aged Decoction) plus Shan Zha (Hawthorn Fruit, for meat retention), Mai Ya (Barley Sprout, for grain retention), Shen Qu (for phlegm-food binding), Zhi Shi (Immature Bitter Orange), and Hou Po (Magnolia Bark, for phlegm-damp binding). For vomiting with water-phlegm complications, use Ping Wei San (Peaceful Stomach Powder) plus Ban Xia (Pinellia Tuber) and Fu Ling (Poria). For vomiting due to Cold invasion with abdominal pain and clear saliva, dispel Cold and resolve accumulation using Zi Su (Perilla Leaf), Wei Jiang (Roasted Ginger), Ju Hong (Red Tangerine Peel), Bai Dou Kou (White Cardamom), Ban Xia, Mu Xiang (Aucklandia Root), and Bai Zhu. For vomiting with Heat complications like anorexia and irritability, clear Heat and descend Qi using Huang Lian, Sheng Jiang (Fresh Ginger), Shen Qu, Zhi Shi, Qing Pi (Green Tangerine Peel), and Da Huang (Rhubarb Root). For vomiting due to turbid pathogens with dizziness and foul breath, resolve turbidity with aromatic herbs using Huo Xiang (Patchouli), Pei Lan (Agastache), Nong Po (likely Hou Po), Bai Zhi (Angelica Dahurica), Chang Pu (Acorus Rhizome), Shen Qu, and Xiang Dou Chi (Fermented Soybean). This pattern is common in summer among those with weak Stomach Qi.
Sudden vomiting with fatigue and spontaneous sweating, indicating acute Stomach Qi injury, requires Fu Zi Li Zhong Tang (Aconite Regulate the Middle Decoction) with increased Bai Zhu. This is a severe vomiting syndrome requiring urgent rescue. Chronic vomiting occurring at fixed times is termed Fan Wei (Reverse Stomach/Regurgitation). It is rare in nursing infants but occasional in childhood. Treatments are divided into Cold, Heat, and Deficiency types: Cold Fan Wei presents with vomiting green fluid and cold extremities; treat with Er Chen Tang plus Ding Xiang (Clove), Fu Zi (Aconite), Gan Jiang (Dried Ginger), and Rou Gui. Heat Fan Wei presents with sour/bitter vomiting, red face, and warm extremities; treat with Er Chen Tang plus Huang Qin (Scutellaria Root) and Huang Lian. Deficiency Fan Wei presents with vomiting undigested food and a soft, powerless pulse; treat with Si Jun Zi Tang (Four-Gentleman Decoction) or Si Wu Tang (Four-Substance Decoction), adjusting according to symptoms and referencing vomiting treatments.
Treatment for "Yue": Loud, forceful, continuous sounds indicate Heat, suitable for purgation. Low, weak, non-ascending sounds indicate Cold, suitable for warming. The general method always involves regulating Stomach Qi. If hiccups are caused by accidental exposure to cold wind (external factor), sipping hot water may settle the Qi and cure the condition without medication.
Treatment for dry nausea: Use Ju Hong decoction with Jiang Zhi (Ginger Juice) and Bai Mi (White Honey), sipped slowly to moisten. Add Chuan Lian (Huang Lian) and Zhu Ru for Stomach Heat; add Pao Jiang for Stomach Cold; add Ren Shen for Stomach Deficiency; add Wu Zhu Yu (Evodia Fruit) for Qi rebellion.
In summary, for early vomiting with nausea, induce vomiting to remove stagnation, then use medicine to settle the Stomach Qi to prevent injury. For chronic persistent vomiting, add heavy-settling herbs to descend rebellious Qi. For chronic Middle Qi Deficiency, harmonize with grain foods or moisten with Yi Tang (Maltose) and Bai Mi. Avoid oily seeds like Tao Ren (Peach Kernel), Xing Ren (Apricot Kernel), Gua Lou (Trichosanthes Fruit), Lai Fu Zi (Radish Seed), and Shan Zhi (Gardenia Fruit) (unless absolutely necessary). These principles must be known.
