夫斑疮病，《内经》与张仲景皆不载，寻摭方论，盖自魏朝，方有以白头赤根者，俗呼
为豌豆，即斑疮也；细粟如麻者，俗呼为麻，即肤疹也。又有大者，俗呼为芋为萍，此皆轻
重之不齐，故命名异耳。《百问》云，悔不得转利。以疮疹发于表，利之则毒瓦斯入里。庞安
常云∶身疼壮热，须少解散，脏闭毒攻，非利不愈，必令汗下。初虞世亦云∶疮疹发于肌肉
，属阳明，古人治法，皆以承气汤利之。诸说矛盾，不无疑误，今皆存之。要当分其未发已
发为治。若其始发，必作寒热如伤寒状，方证所载，耳冷尻冷， 嗽者，皆疮疹证。又小儿
初得，手足搐搦如风痫者，亦疮疹候，便可与宣热拔毒，必须利之。《千金》治豌豆疮初发
欲发者，单煮大黄服之，即明文也。若其已发，只须解肌，用升麻、紫草辈是也。如是分之
，诸说自泮。又此病多因伤寒失于汗下，或时气胜复，岁主客气，及天行疫病，长幼相
染者，当随因辨证治之。其间为倒 最危，宜早为治。
淋洗冲刷治疗大风疮（麻风病引起的严重皮肤溃疡）。
桑叶、荷叶、地黄叶、皂角叶、[此处原文缺字，疑为某叶]、苍耳叶、菖蒲叶、何首乌叶。
以上药材各取等分，晒干后烧至存性（保留药性但炭化），研成细末，使用方法如同敷面的药物。用于洗手、洗脸及清洗身体。
大风恶疾（指麻风病等严重慢性皮肤病），疮疡遍布如荼毒般痛苦，脓液淋漓不尽，眉毛和鬓发脱落，手指脚趾溃烂脱落，肢体顽固麻木且疼痛瘙痒，面色枯槁憔悴，鼻梁塌陷，眼睛溃烂，牙齿松动脱落，嘴唇破裂外翻。这种病症的恶劣程度，没有超过它的了。患有此病的人，百人中无一能活，却仍然贪恋妻儿，执着于名利，做出不仁的行为，仍想继续纵欲，死也不后悔，实在令人深深悲伤。凡是遇到这种疾病，务必严格戒断食盐，以及一切重口味的食物，无论是公事还是私事，都应当全部摒弃，能不接触世俗事务就尽量不接触，断绝喜庆和吊唁往来，隐居在树林深处，按照方法进行治疗，不仅能治愈疾病，还能因此达到神仙般的境界，这就是所谓的因祸得福。
关于斑疮（天花）病，《黄帝内经》和张仲景的著作中都没有记载，查阅搜集方论资料，大概是从魏朝开始，才有提到白头红根的症状，俗称豌豆，就是斑疮；细小如粟米像麻子一样的，俗称麻，就是肤疹（麻疹）。又有较大的，俗称芋或萍，这些都是病情轻重不同，所以命名各异。《百问》说，后悔没有使用通利大便的方法。因为疮疹发于体表，如果通利大便，毒气就会内陷入里。庞安常说：身体疼痛、高热，需要稍微解表发散，如果脏腑闭塞、毒气攻心，不通利大便就不能痊愈，必须让患者出汗并通下大便。初虞世也说：疮疹发于肌肉，属于阳明经，古人治疗方法，都是用承气汤来通利大便。各种说法相互矛盾，不能不让人怀疑有误，现在都保留这些说法。关键在于要区分未发作和已发作两种情况来治疗。如果刚开始发作，一定出现像伤寒一样的寒热症状，方证记载中，耳朵冷、尾骨冷、咳嗽的，都是疮疹的证候。另外小儿刚患病时，手足抽搐像风痫病的，也是疮疹的征兆，就可以给予宣散热邪、拔除毒气的治疗，必须使用通利大便的方法。《千金方》治疗豌豆疮（天花）初发或即将发作的情况，单煮大黄服用，就是明确的条文。如果已经发作，只需要解肌透疹，使用升麻、紫草这类药物即可。这样区分之后，各种说法自然就能化解。此外，此病多因伤寒时失于发汗或通便，或者时气胜复交替，岁运客气影响，以及天行疫病，长幼之间互相传染，应当根据病因辨证治疗。其中出现倒靥（痘疮内陷）的情况最为危险，应当尽早治疗。
To wash and rinse to treat *dafeng chuang* (severe skin ulcers caused by leprosy).
Sang Ye (Mulberry Leaf), He Ye (Lotus Leaf), Dihuang Ye (Rehmannia Leaf), Zaojiao Ye (Gleditsia Sinensis Leaf), [Character missing in original text, likely a type of leaf], Cang'er Ye (Xanthium Leaf), Changpu Ye (Acorus Leaf), Heshouwu Ye (Polygonum Multiflorum Leaf).
Take equal parts of the above herbs, dry them in the sun, burn them until they retain their medicinal properties but are carbonized (*cun xing*), grind into fine powder, and use as a topical facial mask. Apply to wash hands, face, and body.
*Dafeng* (Leprosy) is a malignant disease; sores cover the body causing torment like poison, with pus dripping endlessly; eyebrows and sideburns fall out; fingers and toes ulcerate and detach; limbs suffer from stubborn numbness, pain, and itching; complexion is withered and haggard; nose collapses, eyes ulcerate, teeth loosen and fall out, lips crack and evert. The severity of this condition has no equal. Among those afflicted, not one in a hundred survives, yet they still cling to wives and children, obsess over fame and wealth, act unrighteously, and desire to continue such behavior even unto death without regret, which is deeply sorrowful. Whenever encountering this disease, one must strictly abstain from salt and all strong-flavored foods; both public duties and private affairs should be completely abandoned; avoid secular matters as much as possible, cease attending celebrations or funerals, dwell secluded in forests, and treat according to the method. This will not only cure the disease but may also lead to immortality, which is what is meant by "turning disaster into blessing."
Regarding *ban chuang* (smallpox), neither the *Huangdi Neijing* (Yellow Emperor's Inner Canon) nor Zhang Zhongjing's works record it. Searching collected formulas and theories, it seems to originate from the Wei Dynasty. There were descriptions of lesions with white heads and red roots, commonly called "peas," which is smallpox; lesions fine as millet seeds or hemp grains, commonly called "ma," are measles/rash. Larger ones are commonly called "taro" or "duckweed." These are merely different names due to varying degrees of severity. The *Baiwen* states: "Regret not using purgatives." Since rashes manifest on the exterior, purging causes toxins to sink inward. Pang Anchang stated: For body pain and high fever, slight release of the exterior is needed; if organs are closed and toxins attack, purging is necessary for recovery, requiring both sweating and purging. Chu Yushi also stated: Rashes manifesting in muscles belong to the Yangming channel; ancient treatments used Chengqi Tang to purge. These theories contradict each other, raising doubts of error, yet all are preserved here. The key is to differentiate treatment based on whether the disease has manifested or not. If just starting, symptoms resemble Taiyang syndrome with chills and fever; signs recorded include cold ears, cold sacrum, and coughing, which are rash indicators. Additionally, when children first contract it, convulsions of hands and feet resembling wind epilepsy are also signs of rash; at this stage, one should promote heat dispersion and extract toxins, necessarily using purgation. Qianjin Fang treats early-stage smallpox by decocting Dahuang (Rhubarb Root) alone for oral administration, which is explicit instruction. If already manifested, only muscle-releasing and rash-expelling methods are needed, using herbs like Shengma (Cimicifugae Rhizoma) and Zicao (Arnebiae Radix et Rhizoma). With this differentiation, conflicting theories naturally resolve. Furthermore, this disease often arises from Taiyang syndrome where sweating or purging was neglected, or due to seasonal qi fluctuations, annual guest qi influences, or epidemic diseases spreading among young and old. Treatment should follow syndrome differentiation based on etiology. Among these, *daoyan* (inward collapse of pustules) is the most critical and requires early intervention.
