天泡疮，即丹毒之类而有泡者，由天行少阳相火为病，故名天泡。为火热客于皮肤
间，外不得泄，怫热血液结而成泡，如豌豆疮。根赤头白，或头亦赤，随处而起，若自
里达于外，发在春夏，三焦俱热，则服通圣散。若止从头项、两手起者，此上焦热也，则
服凉膈散。若从身半以下起者，则服黄连解毒和四物汤。若发于秋冬，则宜升麻、葛根、
犀角，或加柏、芩一二味；外敷如马齿苋、吴蓝、赤小豆、苎根之类、皆解毒消肿，可用
于初起之时。或蚶壳、或龟甲、水龙骨各 存性，则收湿生肌，可用于浸淫之后。
痤、小疖、世谓之热疖是也。王注云∶大如酸枣或如豆，色赤而内有脓血也。
海藏云∶汗出见湿，乃生痤痱。痱为疮疖也。
劳汗当风，寒薄为 ，郁乃痤。痤色赤 ,内有脓血。

上细末。姜汁糊丸，梧桐子大。姜汤下三五十丸，食后服。
黑末子 治疖毒。
用羊角连内骨，烧存性为末。酒调三钱，分上下服之，疮可散。
按∶此方未尝用服，盖秘方也。常治面上或身，卒得赤斑，或痒或瘭毒，不治杀人。
以羊角烧存性，研令极细末，以鸡子清涂之甚效。《本草》亦云然。
天泡疮，属于丹毒一类但伴有水泡的病症，是由时行邪气导致少阳相火亢盛而发病，因此命名为天泡。这是因为火热之邪客居于皮肤之间，向外不能宣泄，郁热使血液凝结而形成水泡，类似于豌豆疮（天花）。其根部呈红色、顶端白色，或者顶端也呈红色，随处发作，若病势由内达外，且在春夏季节发作，伴有三焦俱热的症状，则服用通圣散。如果仅从头项、双手开始发作，这是上焦有热，则服用凉膈散。如果从身体下半部开始发作，则服用黄连解毒汤合四物汤。如果在秋冬季节发作，则适宜使用升麻、葛根、犀角，或者加入黄柏、黄芩一两味药；外用可敷马齿苋、吴蓝、赤小豆、苎根之类，这些药物都能解毒消肿，可用于疾病初起之时。或者使用蚶壳、龟甲、水龙骨各烧至存性，研末后使用，可以收湿生肌，可用于病情浸淫扩散之后。
痤、小疖，世人称之为热疖。王冰注释说：大小如酸枣或豆子，颜色发红且内部含有脓血。张元素（海藏）说：出汗后遇到湿气，就会生出痤和痱子。痱就是疮疖。劳累出汗后当风受寒，寒气逼迫体表，郁结而成痤。痤的颜色发红，内部含有脓血。
旋复花丸
旋复花（三两） 防风 白芷 甘菊花 南星 半夏 石膏 川芎 陈皮 白附子（各半两） 蝎梢 僵蚕（炒，各三钱）
以上药物研成细末。用姜汁调和做成丸药，大小如梧桐子。饭后用姜汤送服三五十丸。
黑末子 治疗疖毒。
取羊角连同内部骨头一起烧至存性，研成粉末。用酒调服三钱，分上下半身部位服用，疮毒即可消散。
按语：此方未曾亲自服用过，大概是秘方吧。常用于治疗面部或身体突然出现的赤斑，或者瘙痒或恶疮毒，如果不治疗会致死。将羊角烧至存性，研磨成极细粉末，用鸡蛋清涂抹，效果很好。《本草》中也有这样的记载。
Tianpao Chuang (Blistering Erysipelas) belongs to the category of erysipelas but presents with blisters. It is caused by epidemic pathogens leading to hyperactivity of Shaoyang Ministerial Fire, hence named Tianpao. This occurs because heat-fire pathogenic factors lodge between the skin layers; unable to vent outward, the stagnant heat causes blood coagulation and blister formation, resembling variola vera (smallpox). The base is red with a white head, or the head may also be red. Lesions appear anywhere. If the pathology moves from interior to exterior, occurs in spring and summer, and involves heat in all three Jiaos, Tongsheng San should be administered. If lesions start only on the head, neck, and hands, this indicates heat in the Upper Jiao, so Liangge San should be taken. If lesions start below the waist, Huanglian Jiedu Tang combined with Siwu Tang should be used. If occurring in autumn and winter, Shengma, Gegen, and Xijiao are appropriate, possibly adding one or two herbs such as Huangbai or Huangqin. Externally, Machixian, Wulan, Chixiaodou, or Zhugen can be applied; these herbs detoxify and reduce swelling, suitable for the initial stage. Alternatively, Hake shells, Gujia, or Shuishelongji can be calcined to retain their properties and applied to dry dampness and promote tissue regeneration, suitable after the lesion has spread extensively.
Cuo (Acne-like boils) and Xiao Ji (small furuncles), commonly known as Re Ji (heat boils), are described by Wang Bing: they are sized like sour jujube seeds or beans, red in color, containing pus and blood internally. Zhang Yuansu (Haizang) stated: "Sweating followed by exposure to dampness generates Cuo and Feizi." Feizi refers to furuncles. "Sweat from labor exposed to wind, cold constrains the surface, stagnation leads to Cuo." Cuo appears red with internal pus and blood.
Xuanfu Hua Wan (Inula Flower Pill)
Xuanfuhua (3 liang), Fangfeng, Baizhi, Ganjuhua, Nanting, Banxia, Shigao, Chuanxiong, Chenpi, Baifuzi (each 0.5 liang), Xieshao, Jiangcan (stir-fried, each 3 qian).
Grind all into fine powder. Form pills using ginger juice paste, size of Sophora japonica seeds. Take 30-50 pills with warm ginger decoction after meals.
Heimozi (Black Powder) treats Ji Du (furuncle toxicity).
Burn sheep horn including the inner bone until it retains its properties, grind into powder. Mix with wine, take 3 qian, divided for upper and lower body administration, the toxin will dissipate.
Note: I have not personally used this prescription; it is likely a secret formula. It is often used to treat sudden red patches on the face or body, accompanied by itching or malignant sores, which can be fatal if untreated. Burn sheep horn until it retains its properties, grind into extremely fine powder, apply with egg white; this is very effective. Bencao also records this.
