《病源论》云∶诸阳气在表，阳气盛则表热，因运动劳役，腠理则虚而开，为风邪所客，
风热相搏，留于皮肤则生疮。初作瘭浆，黄汁出，风多则痒，热多则痛，血气乘之，则多脓
血，故名热疮之。
《短剧方》热疮者，起疮便生白脓是也。

《诸病源候论》说：各种阳气在体表，阳气旺盛则体表发热，因为运动劳役，腠理（皮肤纹理及汗孔）空虚而张开，被风邪侵袭，风热相互搏结，停留在皮肤上就生成疮疡。初起时形成脓疱，流出黄色汁液，风邪重则瘙痒，热邪重则疼痛，血气受其干扰，则产生多量脓血，所以称为热疮。
《短剧方》认为，热疮就是疮疡刚起时就生出白色脓液的病症。
《刘涓子鬼遗方》治疗突然发作的热疮的方剂：
取长约二尺的木炭，烧至通红，用两升水浇灌它使蒸汽冒出，收集流出的汁液洗浴患处，即可痊愈。
《录验方》治疗热疮的黄连粉散方：
水银（熬制）、黄连、胡粉（铅粉，熬制，各一两）。
以上三味药，先将黄连捣碎，过筛。然后将三种药物混合均匀，先用盐汤清洗疮面，擦干后敷上药粉，每天两次。
《诸病源候论》说：盛夏月份，人体皮肤腠理开张，容易受到风热侵袭，风热毒气搏结于皮肤，就会生发沸疮。其形态像开水沸腾一样，轻症的，成片如粟米粒大小；重症的，因热汗浸渍而成疮，因此得名，世人称之为“沸子”。
又一方：用新鲜桑叶擦拭患处。
又一方：用酢浆草煮水清洗患处。
《令李方》治疗人体身体热沸生疮的方剂：
矾石（四两，熬制）、白善（六两，熬注：此处“白善”疑为“白垩”或类似矿物药之误，依原文保留）。
以上两味药，研磨过筛，先用布擦拭身体，然后用药粉扑洒，每天两次。
现今考证：《师说》说：嚼疮（注：此处原文似有脱漏或异名，通常指口唇疱疹类，但文中描述似为全身性），是风邪在皮肉之间，夏季蒸腾热气时形成的疮疡，像风矢（风中飞箭般迅速或刺痛感），先痒后痛。颜色赤白相间，隐疹如粟米大小，治疗的方剂如下：
柚叶，煮水清洗患处。
又一方：用粟米粉敷贴患处。
The *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: When various Yang Qi resides in the exterior, an excess of Yang Qi leads to heat in the exterior. Due to physical exertion or labor, the Cou Li (skin texture and pores) become deficient and open, allowing Wind Evil to invade. When Wind and Heat contend with each other and remain in the skin, sores are generated. Initially, pustules form, discharging yellow fluid; if Wind predominates, there is itching; if Heat predominates, there is pain. If Blood and Qi are affected, excessive pus and blood may appear, hence it is named "Re Chuang" (Heat Sore).
The *Duan Ju Fang* (Short Formula Book) describes Re Chuang as a condition where white pus appears immediately upon the formation of the sore.
The *Liu Juanzi Gui Yi Fang* (Liu Juanzi's Ghost Remains Formulas) provides a formula for treating sudden onset Re Chuang:
Take charcoal about two chi long, burn it until red hot, pour two sheng of water over it to generate steam, collect the resulting liquid, and bathe the affected area. This will lead to recovery.
The *Lu Yan Fang* (Recorded Verified Formulas) provides a Huang Lian Fen San (Coptis Powder) for treating Re Chuang:
Shui Yin (Mercurius, quicksilver, calcined), Huang Lian (Coptidis Rhizoma), Hu Fen (Galena/Lead Powder, calcined), each one liang.
Of these three substances, first grind the Huang Lian and sift it. Then mix all three substances thoroughly. Wash the sore with salt water, dry it, apply the powder, twice daily.
The *Zhu Bing Yuan Hou Lun* states: In the height of summer, human skin Cou Li opens, making one susceptible to Wind-Heat. When Wind-Heat toxic qi contends in the skin, Fei Chuang (Boiling Sore) arises. Its appearance resembles boiling water. In mild cases, it appears in clusters like millet grains; in severe cases, hot sweat macerates the skin into sores, giving rise to its name. The world calls it "Fei Zi."
The *Xin Lu Fang* (Newly Recorded Formulas) provides formulas for treating summer heat Fei Chuang:
Sift Duan Shi Fen (Calcined Stone Powder) finely onto the affected area.
Another formula: Rub the affected area with fresh Sang Ye (Mori Folium, mulberry leaf).
Another formula: Boil Su Jiang Cao (Portulacae Herba, purslane) and wash the area.
Another formula: Rub and apply Shui Ping (Pistiae Herba, duckweed) to the area.
Another formula: Crush Tu Si Miao (Cuscutae Herba seedling) and rub/apply it to the area.
The *Ling Li Fang* provides a formula for treating body sores caused by summer heat and boiling sensation:
Fan Shi (Alumen, four liang, calcined), Bai Shan [Note: Likely Bai E (Kaolin) or similar mineral, six liang, calcined].
Grind and sift these two substances. First wipe the body with cloth, then dust with the medicinal powder, twice daily.
Current analysis: The *Shi Shuo* (Master's Sayings) states: Jiao Chuang (Chewing Sore/Mouth Ulcer - *Note: Context suggests a dermatological condition resembling herpes or impetigo described metaphorically*) occurs when Wind Evil resides between the skin and flesh. During the steaming heat of summer, sores form, feeling like wind-driven arrows, starting with itching followed by pain. The color is red and white, with hidden rashes the size of millet grains. Treatment formulas include:
Boiled You Ye (Citrus Maxima Leaf) for washing.
Another formula: Boiled Zhi Zi Ye (Gardeniae Folium) for washing, or grinding Zhi Zi Fen (Gardeniae Fructus Powder) for application.
Another formula: Apply Su Fen (Setaria Italica Flour, millet flour).
For cases with excessive heat causing bleeding:
[Text missing herb name] crushed and juiced, applied topically, and boiled for washing.
