痘疮尚未痊愈，痢疾随即发生，这是湿热之邪损伤中焦，病情并不轻微。白色痢疾属于伤气，可用四君子汤治疗；红色痢疾属于伤血，可用四物汤治疗。
【注】凡是痘疮未愈而患痢疾的，是由于湿热郁结于肠胃，导致气血受损所致，痘疹必然色泽滞暗无光。治疗应当以清热除湿、调理气血为主。白痢属气分病变，用加味四君子汤主治；赤痢属血分病变，用加味四物汤主治；赤白相兼的，将两方合用。

痘疹见点时出现瘙痒，用葛根汤治疗；灌浆期出现瘙痒塌陷，用大补法疗效良好；触犯秽气导致突发瘙痒，用熏避秽香的方法，急煎内托散以免毒邪内藏。
【注】医经说：各种瘙痒多因虚所致。又说：火邪微弱则痒。治疗者必须分别施治。痘疹刚发出而身体瘙痒的，这是邪气欲出，腠理致密，火邪游溢往来，所以不时作痒，用加味升麻葛根汤主治。灌浆时，痘色淡白平塌，大便溏薄食欲不振，浆液清稀且作痒的，这是脾胃虚弱、气血不足的表现，用十全大补汤主治。如果是被秽气触犯而突发瘙痒的，外用避秽香熏蒸，内服内托散将毒邪排出体外，这样就没有毒邪内攻的祸患。至于即将收靥时作痒的，这是脓液已成、毒邪已化，营卫和畅的表现，与疮疖将要痊愈时作痒的情况相同论述，不必服药。

If the smallpox rash has not yet healed and dysentery follows, it indicates that damp-heat has injured the middle jiao (Middle Burner), and the condition is not mild. White dysentery belongs to qi injury and can be treated with Sijunzi Tang (Four Gentlemen Decoction); red dysentery belongs to blood injury and can be treated with Siwu Tang (Four Substances Decoction).
[Note] Whenever a patient suffers from dysentery while the smallpox rash has not yet healed, it is caused by damp-heat stagnating in the intestines and stomach, leading to damage of qi and blood; the pustules will necessarily appear dull, dark, and colorless. Treatment should focus on clearing heat, removing dampness, and regulating qi and blood. White dysentery involves the qi level and is primarily treated with Jiawei Sijunzi Tang (Modified Four Gentlemen Decoction); red dysentery involves the blood level and is primarily treated with Jiawei Siwu Tang (Modified Four Substances Decoction); if both red and white are present, the two formulas are combined.
Jiawei Sijunzi Tang (Modified Four Gentlemen Decoction)
Poria (Fu Ling), Atractylodes Macrocephala Rhizome (Bai Zhu, stir-fried with earth), Ginseng Radix (Ren Shen), Tangerine Peel (Chen Pi), Aucklandia Root (Mu Xiang, baked), Licorice Root (Gan Cao, honey-fried), Coptis Rhizome (Huang Lian, ginger-fried), Scutellaria Root (Huang Qin).
Decoct in water and take orally.
[Formula Song] The modified Four Gentlemen works like magic,
With Poria, Atractylodes, and Ginseng in the bag.
Tangerine peel, Aucklandia, and honey-fried Licorice,
Along with Coptis fried in ginger and Scutellaria nice.
Jiawei Siwu Tang (Modified Four Substances Decoction)
Ligusticum Chuanxiong Rhizome (Chuan Xiong), Angelica Sinensis Radix (Dang Gui), Rehmannia Root (Sheng Di), Scutellaria Root (Huang Qin, wine-fried), Coptis Rhizome (Chuan Lian, wine-fried), Aucklandia Root (Mu Xiang), Paeonia Lactiflora Radix (Bai Shao, stir-fried).
Decoct in water and take orally.
[Formula Song] Modified Four Substances treats red dysentery well,
Chuan Xiong and Dang Gui with Sheng Di dwell.
Scutellaria wine-fried joins with Coptis too,
Aucklandia and Bai Shao blend the remedy through.
When the rash spots appear accompanied by itching, Gegen Tang (Kudzu Decoction) is used; during the filling stage, if itching and collapse occur, great supplementation is beneficial; if sudden itching is triggered by foul odors, fumigation with Bi Hui Xiang (Avoiding Filth Incense) is applied, and Neituo San (Internal Support Powder) is decocted urgently to prevent toxin retention inside.
[Note] The Classics state: "All itching arises from deficiency." It also states: "Weak fire causes itching." Practitioners must differentiate and treat accordingly. When the rash has just emerged and the body itches, this is because the pathogenic factor desires to exit, but the couli (pores) are tight, causing fire to wander back and forth, resulting in intermittent itching; Jiawei Shengma Gegen Tang (Modified Ephedra and Kudzu Decoction) is used. During the filling stage, if the pustules are pale, flat, and collapsed, with loose stools, poor appetite, clear pus, and itching, this indicates spleen and stomach weakness with qi and blood deficiency; Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) is used. If sudden itching is caused by contact with filth, external fumigation with Bi Hui Xiang is used, and internally, Neituo San is taken to expel toxins outward, thereby avoiding the danger of internal attack. As for itching occurring just before scabbing, this indicates that pus has formed and toxins have transformed, and the ying (nutritive) and wei (defensive) qi are harmonious and flowing smoothly; this is discussed similarly to itching when sores and boils are about to heal, and no medication is necessary.
Jiawei Shengma Gegen Tang (Modified Ephedra and Kudzu Decoction)
Ephedra Stem (Sheng Ma), Kudzu Root (Ge Gen), Saposhnikovia Root (Fang Feng), Prepared Soybean (Dan Dou Chi), Red Peony Root (Chi Shao), Cinnamon Twig (Gui Zhi), Licorice Root (Gan Cao, raw).
Decoct in water and take orally.
[Formula Song] Modified Shengma Gegen Tang,
Itching upon rash emergence is its task.
Sheng Ma, Ge Gen, Fang Feng, and Dan Dou Chi,
Chi Shao, Gui Zhi, and Gan Cao make it rich.
Shiquan Dabu Tang (See treatment for crusting and falling off stages for formula details)
Bi Hui Xiang (Avoiding Filth Incense)
