【海藏】疮疹（皮肤出现斑疹的急性传染病）患者口不渴，属脏腑虚寒导致腹泻，用四君子汤（由人参、白术、茯苓、甘草组成，具有益气健脾功效的方剂）加干姜，剂量减半来主治。
痘疹患者大便不能固摄，痘疮逐渐变黑并内陷，小儿与其乳母需同时服药。
药材包括：人参、白茯苓、肉豆蔻、黄芩（各半两）、炙甘草（二钱）。
将上述药材切碎，每次服用一钱，加水半盏，生姜五片，大枣二枚，煎煮至剩余三分之一的药液，乳母服用剂量加倍。如果发生严重腹泻，手足冰冷，加入附子使用可验证疗效。

【世医观点】痘疮呕吐逆乱且无痰饮者，用益黄散；若有痰饮，用二陈汤（由半夏、陈皮、茯苓、甘草组成，具有燥湿化痰功效的方剂）或橘皮半夏汤。若呕吐不止，加入丁香。如果既呕吐又腹泻，也适宜使用益黄散以及陈氏木香散、异功散（在四君子汤基础上加陈皮，具有益气健脾、理气和胃功效的方剂）。若呕吐且伴有身体发热、烦躁口渴、腹部胀满、气喘、大小便不通畅、面色发红者，应当通利小便。若病情未好转，用宣风散攻下治疗。（全文见《大法》篇。）

[Haizang] When patients with chuangzhen (acute infectious diseases characterized by skin eruptions) do not feel thirsty, it indicates coldness in the zang-fu organs leading to diarrhea. This is primarily treated with Sijunzi Tang (Four Gentlemen Decoction, a formula for tonifying qi and strengthening the spleen) combined with Ganjiang (Dried Ginger), with the dosage halved.
For children with douzhen (smallpox/rubella-like eruptions) whose stools are unconsolidated and whose eruptions gradually turn black and sink inward, both the child and their wet nurse should take the medicine simultaneously.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Baifuling (Poria), Roudoukou (Nutmeg), Huangqin (Scutellariae Radix) (each 0.5 liang); Zhigancao (Prepared Licorice Root) (2 qian).
The ingredients are chopped. Each dose consists of 1 qian, boiled with half a zhan of water, five slices of Shengjiang (Fresh Ginger), and two Zao (Jujube fruits), until one-third of the liquid remains. The wet nurse doubles this dose. If severe diarrhea occurs accompanied by cold limbs, Fuzi (Aconiti Lateralis Radix Praeparata) should be added; its efficacy can be verified.
[Chen Wenzhong] Doukou Wan (Cardamom Pill), treats diarrhea caused by douzhen.
Ingredients: Muxiang (Aucklandiae Radix), Sharen (Amomi Fructus), Bailonggu (Fossilized Bones), Hezirou (Pericarpium Arecae Semen), Mianbao Wei Roudoukou (Nutmeg wrapped in flour and roasted) (each 0.5 liang); Chishizhi (Halloysitum Rubrum), Kubaijian (Calcined Alum) (each 7.5 qian).
These are ground into powder and made into pills the size of millet seeds using paste. Children aged one year take thirty pills; those aged three years take one hundred pills, administered with warm rice water. Discontinue use once diarrhea stops.
[General Medical View] For douchuang (smallpox) vomiting without phlegm, use Yihuang San (Yellow Benefiting Powder); if phlegm is present, use Erchen Tang (Two Aged Ingredients Decoction, a formula for drying dampness and resolving phlegm) or Jupi Banxia Tang (Tangerine Peel and Pinellia Decoction). If vomiting persists, add Dingxiang (Caryophylli Flos). If both vomiting and diarrhea occur, Yihuang San, Chen's Muxiang San, or Yigong San (Four Efficacious Agents Powder, a formula for tonifying qi, strengthening the spleen, and regulating qi) are also appropriate. If vomiting is accompanied by fever, irritability, thirst, abdominal fullness, asthma, difficulty in urination and defecation, and red face, diuresis should be promoted. If there is no improvement, Xuanfeng San (Wind-Releasing Powder) should be used to purge. (Full text see "Da Fa" chapter.)
[Danxi] Mianu, after recovering from smallpox, experiences thirst, abdominal urgency/tightness, scanty urine, and fever.

Jizi, aged five, experiences abdominal urgency after smallpox.
Ingredients: Baizhu (Atractylodis Macrocephalae Rhizoma) (1 qian), Chenpi (Citri Reticulatae Pericarpium), Mutong (Akebiae Caulis) (each 5 fen); Xijiao (Rhinocerotis Cornu), Chuanxiong (Ligustici Chuanxiong Rhizoma), Baizhi (Angelicae Dahuricae Radix) (each 7 fen); Zhigancao (Prepared Licorice Root) (3 fen).
Boil in water and take orally.
[Chen Wenzhong] Muxiang San (Aucklandia Powder), treats abdominal distension, thirst, and diarrhea associated with douchuang. (Formula see entry "Dou Ke Xie".)
If abdominal fullness and asthma are present, along with difficulty in urination and defecation, fever, red face, restlessness, and severe vomiting, diuresis should be promoted. If there is no improvement, Xuanfeng San (Wind-Releasing Powder) should be used to purge. (Full text see "Da Fa" chapter.)
