钱氏云∶吐泻，乳不化，伤食也，宜下之。冯承务子五岁，吐泻壮热，不思食饮。钱氏见目中黑睛少而
白睛多，面色 白，曰此子必多病，面色 白者神怯也，黑睛少者肾虚也，黑睛属水，本怯而虚，故多病也，
纵长成，必肌肤不壮，不奈寒暑，易虚易实，脾胃亦怯，更不可纵恣酒欲，若不保养，不过壮年也，面上
常无精神光泽者，如妇人之失血也，今吐利不食壮热者，伤食也。又虚怯不可下，下之，虚入肺则嗽，入心
则惊，入脾则泻，入肾则益虚，但宜以消积丸磨化之，为微有食也。如伤甚，则可下，不下则成癖也。若实
食在内，亦可下也，下毕，补脾必愈，随其虚实，无不效者。〔曾〕钱氏曰∶吐乳泻黄，是伤热乳，吐
乳泻青，是伤冷乳，皆当下之，此迎夺之法也。不若伤热者用五苓散以导其逆，伤冷者用理中汤以温其中，
自然平复。脾经积滞未除，再为饮食所伤，不吐则泻，不泻则吐，宜以三棱散化积，守胃散和中。

钱乙说：吐泻，乳汁不消化，是伤食所致，适宜采用攻下法。冯承务的儿子五岁，出现吐泻、壮热，不想进食饮水。钱乙观察到孩子黑睛少而白睛多，面色苍白，说这个孩子一定多病，面色苍白说明神气怯弱，黑睛少说明肾虚，黑睛属水，本性怯弱且虚，所以容易生病，即使长大成人，也必定肌肉不健壮，不耐寒暑，容易虚实变化，脾胃也怯弱，更不可放纵酒欲，如果不保养，活不到壮年。面上常无精神光泽的，就像妇人失血一样。现在吐利不食、壮热的，是伤食。另外，虚怯之体不可攻下，攻下后，邪气入肺则咳嗽，入心则惊悸，入脾则泄泻，入肾则更加虚弱，只适宜用消积丸磨化积滞，因为只是轻微有食积。如果伤食严重，则可以攻下，不攻下则会形成癖积。如果是实食在体内，也可以攻下，攻下之后，补脾必然痊愈，根据虚实情况辨证施治，没有不有效的。〔曾〕钱乙说：吐乳泻黄，是伤热乳；吐乳泻青，是伤冷乳，都应当攻下，这是迎夺的方法。不如伤热的用五苓散来引导逆气，伤冷的用理中汤来温暖中焦，自然平复。脾经积滞未除，再次被饮食所伤，不吐就泻，不泻就吐，适宜用三棱散化解积滞，守胃散调和胃气。

Guizhi Lingzao Tang (Cinnamon Twig and Poria Decoction): Treats vomiting and diarrhea caused by dampness invading the stomach and intestines.
Ingredients: Atractylodis Macrocephalae Rhizoma, Poria, Alismatis Rhizoma, Magnoliae Officinalis Cortex, Polyporus, Citri Reticulatae Pericarpium, Glycyrrhizae Radix et Rhizoma (stir-fried, equal parts), Cinnamomi Ramulus (a small amount).
Usage: Grind the above ingredients into fine powder. Take two qian per dose, mixed with a decoction of fresh ginger, Juncus effusus, and Citri Reticulatae Pericarpium. If vomiting and diarrhea are due to food stagnation, accompanied by scanty urination, abdominal distension and pain, use this formula to separate and drain dampness. Subsequently, use Liujunzi Tang (Six Gentlemen Decoction) to regulate and tonify the spleen and stomach.
Banli San (Half-Millet Powder): Treats vomiting and diarrhea due to deficiency-cold of the spleen and stomach in children, as well as cold-phlegm.
Ingredients: Pinelliae Rhizoma (soaked in water, sliced, dried, 1 liang), Setaria Italica (3 fen, aged Oryzae Fructus Glutinosus is also acceptable).
Usage: Cut the herbs into small pieces. Take 3 qian per dose, boil with 1.5 large cups of water and 10 slices of fresh ginger until reduced to 0.8 cup, take warm before meals.
Baifu Wan (White Head Pill): Treats phlegm-saliva.
Qian Yi stated: Vomiting and diarrhea with undigested milk indicate food injury; purgation is appropriate. The son of Feng Chengwu, aged five, suffered from vomiting, diarrhea, high fever, and anorexia. Qian Yi observed that the child had less black iris and more white sclera, with a pale complexion, stating that this child would likely suffer from frequent illnesses. A pale complexion indicates deficient spirit; less black iris indicates kidney deficiency. Since the black iris corresponds to Water, inherent weakness and deficiency lead to frequent illness. Even if he grows up, his muscles will not be robust, he will not tolerate cold or heat, his condition will easily shift between deficiency and excess, and his spleen and stomach will also be weak. He must not indulge in alcohol; without proper care, he will not reach middle age. A face lacking spiritual luster resembles blood loss in women. Current symptoms of vomiting, diarrhea, anorexia, and high fever indicate food injury. Furthermore, those with deficiency and timidity should not be purged; purging causes pathogenic factors to enter the Lung causing cough, the Heart causing palpitations/fright, the Spleen causing diarrhea, and the Kidney exacerbating deficiency. It is better to use Xiaoji Wan (Accumulation-Dissolving Pill) to grind down accumulation, as there is only slight food retention. If the injury is severe, purgation can be used; otherwise, it may develop into a mass (Pi Ji). If solid food remains internally, purgation is also applicable. After purgation, tonifying the Spleen ensures recovery. Following deficiency and excess patterns, efficacy is guaranteed. [Zeng] Qian Yi said: Vomiting milk with yellow stool indicates hot milk injury; vomiting milk with green stool indicates cold milk injury. Both require purgation, which is the method of "attacking and seizing." However, for hot injury, Wuling San (Five-Ingredient Powder with Poria) is used to guide rebellious qi downward; for cold injury, Lizhong Tang (Regulate the Middle Decoction) is used to warm the middle jiao, leading to natural recovery. If spleen meridian stagnation persists and is re-injured by diet, resulting in alternating vomiting and diarrhea, Sanleng San (Curcuma Powder) should be used to resolve accumulation, and Shouwei San (Stomach-Guarding Powder) to harmonize the stomach.
