用法用量：加入生姜三片、大枣三枚，加水煎煮，趁热服用。
若小儿呕吐时，外在表现无发热、无口渴，面色苍白、嘴唇色淡，精神萎靡、气息怯弱，此为寒性呕吐。治疗方法：取一大块生姜，直切成薄片，注意不要折断，层层撒上盐，用麻绳紧紧扎住，外层再用七层草纸包裹，沾湿后用慢火煨烤至熟透。取出后，去掉麻绳和纸张，将生姜捣烂，与早米一起煎汤服用，可立即止吐。
若小儿突然呕吐不止。治疗方法：取生姜榨取自然汁一盏，煮沸备用；蜂蜜四两，炼制成熟备用。每次服用时，取姜汁一匙、蜂蜜两匙，用白开水调匀服用，每日服用五六次，可见效。
若小儿因胃热引起呕吐。外在表现为面红、烦躁不安、身体发热且口渴、手心脚心发热，此为热性呕吐。治疗方法：黄连一钱（用姜汁炒制）、熟石膏一钱，共同研磨成细末，每次服用一钱，用白开水调服。待呕吐停止后，再服用后续药物，并使用枇杷叶在火上炙烤，刷净绒毛，每次取三片叶子，煎汤趁热服用，可立即止吐。

凡是呕吐患者服药后无法接纳（即服后即吐），是因为体内膈间有蛔虫。蛔虫闻到药气就会躁动，躁动则导致药液吐出而蛔虫未除。只需在治呕吐的药方中加入川椒十四粒，即可不再呕吐，因为蛔虫遇到花椒就会安静潜伏。
治疗小儿各种类型的吐逆，不分寒热，以及长期呕吐服用多种药物无效的情况。治疗方法：取硫黄五钱、水银一钱，共同研磨直至看不见银色星点，用姜汁调和，以米糊制成如小豆大小的丸剂。三岁儿童服用三丸，成人服用三四十丸，用阴阳水送服。这两种药材增加分量后，放入阳城罐内密封，用炭火升炼，即为灵砂，是道家仙人所用的物品。此药最能升降阴阳，协调水火，是挽救危局、救济困境的神丹妙药。

If a child vomits without external signs of heat or thirst, with a pale face and lips, listless spirit, and timid breath, this is cold-type vomiting. Treatment: Take a large piece of Shengjiang (Fresh Ginger), slice it straight into thin slices without breaking them. Layer the slices with salt, bind tightly with hemp rope, wrap in seven layers of straw paper, wet the paper, and slow-roast until cooked. Remove, discard the rope and paper, mash the ginger, and decoct with early rice to make a soup. Drink immediately to stop vomiting.
If a child suddenly vomits continuously: Treatment: Extract natural juice from Shengjiang (Fresh Ginger), one cup, boil and set aside; refine Si Mi (Honey), four liang, and set aside. For each dose, mix one spoonful of ginger juice with two spoonfuls of honey, take with warm water. Repeat five to six times daily for effectiveness.
If a child suffers from vomiting due to Stomach heat, manifested by a red face, restlessness, body heat with thirst, and heat in the palms and soles, this is heat-type vomiting.

Take 1 qian per dose, mixed with warm water. After vomiting stops, continue medication. Additionally, roast Pi Pa Ye (Loquat Leaf) over fire, brush off hairs, use three leaves per dose, decoct in water, and take hot to stop vomiting immediately.
Dry heaving in children is an extremely difficult condition. Treatment: Prepare juice from Gan Zhe (Sugarcane) and juice from Shengjiang (Fresh Ginger). Before administration, mix six spoonfuls of sugarcane juice with two spoonfuls of ginger juice, warm and take evenly. Do not dilute with water.
In cases where vomiting patients cannot retain medicine, it is often because Ascaris (roundworms) are present in the diaphragm area. The worms move upon smelling the medicine, causing the medicine to be expelled while the worms remain. Simply add fourteen grains of Chuanjiao (Sichuan Pepper) to the anti-emetic medicine, and vomiting will cease, as the worms subside upon encountering pepper.
To treat all types of regurgitation and vomiting in children, regardless of cold or heat, and for chronic vomiting unresponsive to various medicines: Treatment: Mix Liu Huang (Sulfur, 5 qian) and Shui Yin (Mercury, 1 qian), grinding together until no silver specks are visible. Form pills using Ginger Juice and rice paste, sized like small beans. Children aged three take three pills; adults take thirty to forty pills. Wash down with Yin-Yang Water (a mixture of fresh and boiled water). If these two ingredients are increased in proportion, sealed in a Yangcheng jar, and refined over charcoal fire, they become Lingsha (Spirit Sand), a substance used by Daoist immortals. It can best regulate the ascending and descending of Yin and Yang, harmonizing Water and Fire, serving as a miraculous elixir to rescue critical conditions.
