经曰∶脉风成为疠，俗呼癞风是也。
〔丹〕云∶大风病，是受得天地间杀物之风，古人谓之疠风，以其酷烈暴悍可畏尔。人得之者，须分在上
在下。夫在上者，以醉仙散取臭恶血于齿缝中出。在下者，以通天再造散取恶物蛔虫于谷道中出。所出虽有上
下道路之异，然皆不外于阳明一经而已。看其疙瘩，上先见，在上体多者，病在上也。下先见，在下体多者，
病在下也。上下同得者，病在上复在下也。阳明主胃与大肠，无物不受。此风之入人也，气受之在上多，血受
之在下多，血气俱受者上下皆多，自非医者有神，病者有铁心，罕有免者。余曾治四五人，中间唯一妇人得免，
以其贫甚，无物可吃也。孙真人曰∶吾尝治四五百人，终无一人免者。非真人之不能治也，第无一人能守禁忌耳。

The *Classic of Medicine* (*Huangdi Neijing*) states: "When the pulse is affected by wind and transforms into Leprosy (Lifeng), it is commonly known as 'Lai Feng' (scabies-like wind disease)."
Mr. Danxi (Zhu Zhenheng) said: "The Great Wind disease (i.e., Leprosy/Lifeng) results from contracting the killing wind of heaven and earth, which the ancients called Lifeng because its nature is fierce, violent, and terrifying. Upon contracting this disease, one must distinguish whether the pathology is located in the upper or lower body. For pathology in the upper body, use Zuixian San (Immortal's Elixir Powder) to induce the discharge of foul blood through the gum fissures. For pathology in the lower body, use Tongtian Zaizao San (Sky-Penetrating Rebirth Powder) to induce the discharge of foul matter and roundworms through the anus. Although the pathways of discharge differ between upper and lower, they all pertain to the Yangming Meridian (the meridians of the Stomach and Large Intestine). Observe the nodules: if they appear first on the upper body and are more numerous there, the disease is in the upper part; if they appear first on the lower body and are more numerous there, the disease is in the lower part; if both upper and lower are equally involved, the disease affects both. The Yangming Meridian governs the Stomach and Large Intestine, accepting all things. When this wind pathogen enters the human body, Qi deficiency predominates in the upper part, Blood deficiency predominates in the lower part, and when both Qi and Blood are affected, both upper and lower parts are heavily involved. Unless the physician possesses divine skill and the patient has an iron will (to strictly observe dietary restrictions), few will escape. I once treated four or five patients, among whom only one woman recovered because she was extremely poor and had no food to eat (thus inadvertently avoiding forbidden foods). Sun Simiao said: 'I have treated four or five hundred patients, and not a single one survived.' This is not because Master Sun could not cure them, but because no one could abide by the dietary taboos."
The general principle for treatment is that for severe cases, one should employ methods to purge accumulation and induce sweating.

Mr. Yuan (Li Dongyuan) recorded: Officer Duan suffered from Leprosy, with his entire face and beard extremely itchy, and eyebrows already fallen out. Hot water pouring provided slight relief, required several times day and night; acupuncture also provided relief. My teacher (Zhang Congzheng/Zhang Yuansu) said: In the *Discourse on Wind*, it is stated: "In Leprosy, Ying and Wei heat stagnates, causing turbid Qi, leading to nasal collapse, facial discoloration, and skin ulcers. Wind and Cold lodge in the vessels and do not depart, named Leprosy." Treatment involves needling the swollen area with a sharp needle to extract evil Qi until swelling subsides. Diet should remain normal; avoid other foods. If using herbs, one must break blood, clear heat, raise Yang, stop itching, drain Ying, disperse with pungent-cold herbs, raise with sweet-warm herbs, circulate the Yangming Meridian, drain Heart Fire, and tonify Lung Qi. This is the correct treatment.

**Chengjiang Acupoint**: Located in the depression anterior to the chin, below the lower lip. It is the meeting point of the Foot-Yangming Stomach Meridian and the Ren Mai (Conception Vessel).
