Treats dysentery with profuse watery diarrhea (Dongxie, referring to severe diarrhea where stool flows down like water) and internal invasion of cold pathogen during pregnancy.
Ganjiang (Dried Ginger), Houpo (Magnolia Bark, remove coarse bark, finely sliced).
Equal parts of the above two herbs. First pound them until soft, mix with water, stir-fry together until dry, then grind into powder. Use wheat paste made by boiling flour in water as a binder to form pills the size of Sophora seeds. Take 50 pills per dose, before meals, washed down with rice water.

Treats conditions where the visceral qi is inherently deficient during pregnancy, with a history of wind-cold accumulation, long-term weakness of the spleen and stomach, and deficiency-induced laxity of the viscera, resulting in pain around the umbilicus and abdomen, and unceasing diarrhea day and night.
Houpo (Magnolia Bark, remove coarse bark, soak in ginger juice, stir-fry until yellow, 2 liang), Roudoukou (Nutmeg, one piece, baked in flour), Caodoukou (Cardamom, one piece, baked).
Chop the above herbs. Take 3 qian per dose. Add one盏 (approx. 200ml) of water and three slices of ginger, decoct until the volume reduces to 70%, strain, and take hot.
Sanhuang Shuai Ai Tang (Three-Yellow Prepared Mugwort Decoction; see Volume 8, Treatise 10 for formula), Lizhong Wan (Regulate the Middle Pill), Lizhong Tang (Regulate the Middle Decoction), Wuling San (Five-Ling Powder), Huanglian Ejiao Wan (Coptis and Donkey-Hide Gelatin Pill), Wuji Wan (Wu-Ji Pill), Yinggan Wan (Responsive Pill). All the above formulas are found in *Heji Jufang* (Formulary of the Bureau of Preserving Health).

Discussion states: In pregnant women, since the blood in the uterus is retained to nourish the fetus, the qi mechanism of the viscera becomes disordered, making the spleen and stomach prone to injury; or due to excessive consumption of fishy, greasy, and raw/cold foods, causing stagnation in the spleen and stomach and inability to transform and transport. Cold and heat pathogens contend with each other, causing churning and stabbing pain in the heart and abdomen, with pus, blood, red, and white matter mixed in the stool. Ancient texts refer to this as "Zhixia" (Stagnant Downward Flow). The origin of this disease lies in the imbalance of cold and heat, deficiency-cold of the large intestine, and heat pathogen lodging in the intestines. When heat pathogen attacks, the stool appears red; when cold pathogen attacks, it appears white. When cold and heat interact, red and white mix, and transportation stagnates while fluid discharge stops, named "Zhi Li" (Stagnant Dysentery). Its presentation involves white pus resembling mucus mixed with blood, sometimes with less blood. If the white pus contains red streaks resembling fish brain, it is called "Yunao Li" (Fish Brain Dysentery). There is also bloody dysentery, caused by heat invading the blood and entering the large intestine, forming bloody dysentery. Blood follows qi, circulating externally through meridians and internally connecting to viscera, usually without stagnation. If exposed to labor or movement generating heat, the heat causes blood to scatter and seep into the large intestine. Due to intestinal deficiency, transformation occurs, thus forming bloody dysentery.

To treat dysentery with pus and blood resembling fish brain marrow during pregnancy, accompanied by unbearable cramping pain in the lower abdomen, use Diyue San (Sanguisorba Powder).
Ejiao (Donkey-Hide Gelatin, roasted, 2 liang), Diyue (Sanguisorba Root), Suan Shiliu Pi (Acid Pomegranate Peel, 3 liang), Xiebai (Allium Macrostemon Bulb, cut, 1 sheng), Huanglian (Coptis Rhizome; in some prescriptions, Huangbo Pi [Phellodendron Bark] is used instead. Each 3 liang, all finely cut).
Add seven sheng (approx. 1400ml) of water, decoct to obtain two sheng (approx. 400ml) of liquid. Divide into three doses and take warm. Avoid raw/cold and greasy foods.
