(Referred to as "Water and Grain Diarrhea" in medical texts)
[Qian Yi] Indigestion of food is due to cold deficiency of the Spleen and Stomach, hence the inability to digest. It should be primarily treated with Bupi Yihuang San (Spleen-Nourishing Yellow-Improving Powder). [Zhang Congzheng] Indigestion of milk and food, initially presenting with sudden cold breath and cold limbs, pale lusterless complexion, and unsettled spirit, indicates disharmony of Stomach Qi. It can be treated with strongly warming medicines, using Shijunzi Wan (Quince Seed Pill) or Yihuang San (Yellow-Improving Powder) as primary treatments. If diarrhea persists for a long time without improvement, and milk/food remains undigested, it indicates Wind-Cold in the Spleen and Stomach. First, take two doses of Yihuang San, then use Xuanfeng San (Wind-Releasing Powder) to guide/drain. The Stomach Qi should be tonified again; refer to the "Sun Xie Section" of Da Ke for application.
Shenghui Fang's Nongpu San treats pediatric Water and Grain Dysentery/Diarrhea, emaciation, yellowish complexion, and anorexia.

Each half liang) Dingxiang (Caryophylli Flos) Danggui (Angelicae Sinensis Radix, chop, lightly stir-fry) Muxiang (Aucklandiae Radix) Baizhu (Atractylodis Macrocephalae Rhizoma) Roudoukou (Myristicae Semen, each one fen).
The above herbs are pounded, finely sifted into powder. Each dose: mix half qian with rice water, taken orally. Three to four times daily. Adjust dosage according to the child's age and size.
Diyu San treats Water and Grain Diarrhea that does not cease day or night.
Diyu (Sanguisorbae Radix, lightly roasted, chopped) Nongpu (Magnoliae Officinalis Cortex, remove coarse bark, coat with fresh ginger juice, roast until fragrant and cooked. Each three fen) Huanglian (Coptidis Rhizoma, one liang, remove stamens, lightly stir-fry) Ejiao (Colla Corii Asini, half liang, crush, stir-fry until yellow).
The above herbs are pounded, finely sifted into powder. Take at any time, mix half qian with rice water. Adjust dosage according to the child's size.
Yiju Fang's Weifeng Tang treats Wind-Cold invading the intestines and stomach due to deficiency, causing indigestion of water and grain, profuse watery diarrhea, abdominal and hypochondriac fullness, borborygmus, and pain.
It is also suitable for cases where damp-toxin from the intestines and stomach discharges downward like bean curd residue, or dark blood, occurring day and night without restraint.
Renshen (Ginseng Radix et Rhizoma, remove rhizome head) Baifuling (Poria, remove skin) Xiong (Ligustici Chuanxiong Rhizoma) Guipi (Cinnamomi Cortex, remove coarse bark) Danggui (Angelicae Sinensis Radix, remove sprouts) Baishaoyao (Paeoniae Radix Alba) Baizhu (Atractylodis Macrocephalae Rhizoma, all equal parts).
Make into a coarse powder. Each dose: two qian, decoct with one large cup of water and one hundred grains of millet until reduced to seven-tenths. Strain and drink slightly warm. Take on an empty stomach before meals. Reduce dosage for children.
Pediatric stool appearing as green clumps in Sun Xie (undigested food diarrhea), with a large pulse and cold hands and feet, is difficult to cure; with a small pulse and warm hands and feet, it is easy to cure.
