For vomiting and diarrhea, only when it is clearly known to be caused by food stagnation or cold invasion can one use formulas for resolving stagnation and guiding out food, such as Zhizhu Erchen Tang (Bitter Orange and Atractylodes with Two-Ingredient Decoction) or Pingwei San (Stomach-Pacifying Powder). Other cases of vomiting and diarrhea are caused by Liver Wood overacting on Spleen Earth; they should be immediately settled with Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Decoction), which is infallible. During the summer months, it is especially appropriate to tonify healthy Qi. For vomiting, add Banxia (Pinelliae Rhizoma) 7 fen (processed with ginger juice); for diarrhea, add Baishao (Paeoniae Radix Alba) 1 qian (washed with wine and stir-fried).

Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Decoction)
Baizhu (Atractylodis Macrocephalae Rhizoma), Renshen (Ginseng Radix et Rhizoma), Fuling (Poria), Huoxiang (Agastaches Herba), Muxiang (Aucklandiae Radix), Gan Ge (Puerariae Radix), Gancao (Glycyrrhizae Radix et Rhizoma).
Use Wei Jiang (Roasted Ginger) as a guide.

For Jing Bing (Startling Disease), regardless of severity, use Wuyi Yigong San (Five-Agent Yi-Gong Powder) alone, adding Ruan Chaihu (Soft Bupleuri Radix) and Goutenggou (Uncariae Ramulus cum Uncis). If the condition is due to startling by external objects, it is also because the Wood Qi is deficient and thus susceptible. Do not administer Bao Long Wan (Dragon-Holding Pill) or Zhen Jing Wan (Calming Startling Pill). (Some children suffering from exogenous pathogens present with a fine and rapid pulse at onset; if unresolved for a long time, symptoms such as upward deviation of the eyes and hand spasms appear, indicating a deteriorated condition. As stated in *Yiyu Cao*, "Shanghan" (Cold Damage) is not "Jing Feng" (Wind of Startling). Nowadays, people often treat this as Wind of Startling, which frequently leads to danger. They do not realize that this condition is similar to critical Shanghan patterns in adults, originating from congenital Yin deficiency, hence the fine and rapid pulse. It should be treated according to Liuwei Zuogui (Six-Ingredient Left-Restoring Decoction), although it remains critical.)

For Gan Bing (Childhood Malnutrition Syndrome), whether it is the deficiency or excess type among the Five Gan syndromes, use Wuyi Yigong San (Five-Agent Yi-Gong Powder) alone, adding Huanglian (Coptidis Rhizoma) and Muxiang (Aucklandiae Radix), which is infallible. However, if the child has a large head, distended abdomen, visible veins, and thin limbs, even Huanglian and Muxiang should not be used; instead, Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) should be used exclusively. If Gan Bing is accompanied by intestinal parasites, add Xama (Bufo bufo gargarizans, Toad) and Chuanlian (Coptidis Rhizoma) to Wuyi Yigong San; the stool will necessarily resemble water, dark red, and residue-free. Even after months or years, each dose of Wuyi Yigong San may include one Jiuzhi Xama (Toad roasted with wine) and 5 qian of Chuanlian (stir-fried with ginger juice). (For various syndromes including vomiting, diarrhea, startling, and Gan, one should primarily refer to *Baoying Quanshu* compiled by Xue Changzhou [Xue Shengbai]; this text is somewhat incomplete in comparison.)
