小儿多因饮食之时，忽被惊邪所触而吐，其证频吐青涎，身体发热，心神烦躁，睡卧不宁，古法主先用全蝎
观音散截其风〔如人参、蜜制黄 、炒扁豆、茯苓、莲肉、煨木香、白芷、羌活、防风、天麻、全蝎（去毒）、
炙甘草，共为细末，姜、枣煎汤调服〕。
次用定吐丸止其呕（如丁香二十一粒，蝎梢四十九条，姜制半夏三个，共为细末，令匀煮枣肉为丸，如黍米大，每
服七丸，白滚汤化服）。
〔真按〕小儿因夹惊而吐，古人散剂丸剂，均不宜服，但用朱茯苓钱半，姜汁炒竹茹一钱，天竺黄一钱，
连翘壳八分，生甘草梢五分，先以金银器煎汤，再煎药服。
小儿饮水过多，以致停留胸膈，变而为痰，痰因气逆，遂成呕吐之证，其候头目眩晕，面青，呕吐痰水涎沫也。
古法主香砂二陈汤（如二陈汤本方加藿香、砂仁）。
虚者古方主香砂六君子汤（如六君子汤本方加藿香、砂仁）。
〔真按〕小儿因痰饮而吐，但用化州橘红一钱，炒茯苓钱半，半夏曲八分，藿香叶五分，川朴花一朵，炙
甘草三分，引用北干姜一薄片，虚者加炒党参八分，炒白术一钱。
小儿虫吐之证有二∶（甲）因胃经热蒸而吐；（乙）因胃经寒迫而吐，皆能令虫不安，扰乱胃中而作吐也，
其证唇色或红或白，胃口时痛时止，频呕清涎。属寒属热，当从阴阳之证辨之。热者，古法主化虫丸（如芜荑、
鹤虱、苦楝根皮、胡粉、使君子肉、槟榔、枯矾，共为细末，面糊为丸）量儿大小与之。寒者，古法主加减理中
汤（如人参、干姜、炒白术、川椒，引用乌梅一个）。
〔真按〕小儿因虫而吐，不但治吐，且当治虫。热者，但用淡竹茹二钱，花槟榔八分，使君子肉一钱，芜
荑三分，雷丸三分，炙甘草五分。寒者，除去淡竹茹不用，加川朴五分，木香五分。
Pediatric vomiting often occurs when a child is suddenly affected by "startling pathogenic factors" (Jing Xie, pathogenic factors causing fright) during feeding. The clinical manifestations include frequent vomiting of greenish saliva, fever, mental restlessness, and disturbed sleep. Ancient methods advocate first using Quanxie (Scorpio) and Guanyin San (Bodhisattva Powder) to pacify wind [Formula composition: Renshen (Ginseng Radix), Zhi Huangqi (Honey-processed Astragali Radix), Chao Bian Dou (Stir-baked Lablab Seed), Fuling (Poria), Lian Rou (Lotus Seed Cotyledon), Wei Muxiang (Baked Aucklandiae Radix), Baizhi (Angelicae Dahuricae Radix), Qianghuo (Notopterygii Rhizoma et Radix), Fangfeng (Saposhnikoviae Radix), Tianma (Gastrodiae Rhizoma), Quanxie (Scorpio, detoxified), Zhi Gancao (Honey-processed Glycyrrhizae Radix), ground into fine powder, taken with decoction of Shengjiang (Zingiberis Rhizoma Recens) and Dazao (Jujubae Fructus)]. Subsequently, Dingtu Wan (Vomiting-Stopping Pill) is used to stop vomiting [Formula composition: Dingxiang (Caryophylli Flos, 21 grains), Xieshao (Scorpio tail, 49 pieces), Jiang Banxia (Ginger-processed Pinelliae Tuber, 3 pieces), ground into fine powder, mixed evenly, formed into pills with cooked Jujube flesh, size of Setaria italica seeds, each dose 7 pills, dissolved in warm water].
[Chen Shouzhen's Note:] For pediatric vomiting due to startling, ancient powders and pills are not suitable for administration. Instead, use Zhufuling (Poria processed with Cinnabar) 1.5 qian, Jiangzhu Ru (Bamboo Shavings stir-fried with Ginger Juice) 1 qian, Tianzhuhuang (Calami Humoris) 1 qian, Liaoqiao Ke (Forsythiae Fructum shell) 8 fen, Sheng Gancao Shao (Tip of raw Glycyrrhizae Radix) 5 fen. First decoct with silver vessels, then decoct the herbs in that liquid for administration.
When children drink excessive water, it stagnates in the chest and diaphragm, transforming into Phlegm-Fluids (Tan Yin). The phlegm follows rebellious Qi upward, resulting in vomiting. Symptoms include dizziness, cyanotic complexion, and vomiting of phlegm-fluids and saliva. Ancient methods advocate Xiangsha Erchen Tang (Aucklandia and Amomum Decoction modified from Two Old Ingredients Decoction) [Formula: Erchen Tang base plus Huoxiang (Agastaches Herba), Sharen (Amomi Fructus)]. For deficiency patterns, ancient formulas advocate Xiangsha Liujunzi Tang (Aucklandia and Amomum Six Gentlemen Decoction) [Formula: Liujunzi Tang base plus Huoxiang, Sharen].
[Chen Shouzhen's Note:] For pediatric vomiting due to Phlegm-Fluids, use Huazhou Juhong (Exocarpium Citri Grandis from Huazhou) 1 qian, Chao Fuling (Stir-baked Poria) 1.5 qian, Banxia Qu (Pinelliae Fermented Paste) 8 fen, Huoxiang Ye (Agastaches Folium) 5 fen, Chuanpuhua (Magnolia Flower) 1 flower, Zhi Gancao (Honey-processed Glycyrrhizae Radix) 3 fen, with Beiganjiang (Northern Dried Ginger) 1 thin slice as an adjuvant. For deficiency patterns, add Chao Dangshen (Stir-baked Codonopsis Radix) 8 fen, Chao Baizhu (Stir-baked Atractylodis Macrocephalae Rhizoma) 1 qian.
There are two types of pediatric vomiting caused by parasites: (A) Vomiting due to heat steaming in the Stomach Meridian; (B) Vomiting due to cold forcing in the Stomach Meridian. Both cause parasites to become restless and disturb the Stomach, leading to vomiting. Symptoms include lips being either red or white, intermittent epigastric pain, and frequent vomiting of clear saliva. Whether it is cold or heat should be differentiated based on Yin and Yang patterns. For heat patterns, ancient methods advocate Huachong Wan (Parasite-Expelling Pill) [Formula composition: Wuyi (Quisqualis Semen), Leshi (Artemisiae Argyi Fructus), Kulian Genpi (Meliae Cortex), Hufen (Lead White), Shijunzi Rou (Seed of Quisqualis Indica), Binglang (Arecae Semen), Kufan (Alumen), ground into fine powder, formed into pills with flour paste], administered according to the child's age and size. For cold patterns, ancient methods advocate Jiajian Lizhong Tang (Modified Replenishing the Middle Decoction) [Formula composition: Renshen (Ginseng Radix), Ganjiang (Zingiberis Rhizoma), Chao Baizhu (Stir-baked Atractylodis Macrocephalae Rhizoma), Chuanjiao (Sichuan Pepper), with Wumei (Mume Fructus) 1 piece as an adjuvant].
[Chen Shouzhen's Note:] For pediatric vomiting due to parasites, one must treat both the vomiting and the parasites. For heat patterns, use Dan Zhuru (Light Bamboo Shavings) 2 qian, Hua Binglang (Flower Arecae Semen) 8 fen, Shijunzi Rou (Seed of Quisqualis Indica) 1 qian, Wuyi (Quisqualis Semen) 3 fen, Leiwan (Omphalia Lapida) 3 fen, Zhi Gancao (Honey-processed Glycyrrhizae Radix) 5 fen. For cold patterns, omit Dan Zhuru, and add Chuanpu (Magnolia Bark) 5 fen, Muxiang (Aucklandiae Radix) 5 fen.
