《经》所载疠风者，即方论中所谓大风恶疾癞是也。虽名曰风，未必皆因风，大率多是
嗜欲劳动气血，热发汗泄，不避邪风冷湿，使淫气与卫气相干，致肌肉贲 ，气有所凝

《黄帝内经》所载的疠风病，就是方论中所谓的大风恶疾癞（麻风病）。虽然名为“风”，未必都是由外感风邪引起，大多是因为嗜欲过度、劳倦耗伤气血，导致内热发作、汗出泄气，又不避开邪风冷湿侵袭，使得淫邪之气与卫气相互干扰，致使肌肉肿胀隆起，气机凝滞，则肌肉失去知觉；营血涩滞浑浊，则热气不利，所以面色败坏，皮肤溃疡腐烂，鼻梁塌陷毁坏，《千金方》所说的自作不仁极猥琐之事，虽有悔过之言，却无悔改之心，确实符合实际情况。然而也有因传染而得的，并非自身所致，这是不谨慎的缘故。气血相传，难道是前世业缘会合所导致的吗？推究其病因，都是不内外因和外感因素结合而成的。证候表现多种多样，详见后文。
凡是治疗大风病，必须推究其病因。凡是因风寒湿热、劳逸饮食以及传染引起的，不可混淆滥治。散寒湿风湿、清热、调和气血，各自不同，如果一概用泻风药来治疗，就失去了治疗的机要了。过去曾见一僧人患病，症状像白癞（白癜风或麻风早期），突然没有形成疮疡，只是每天早晨起床时脱落约一升多的白皮，像蛇蜕皮一样。医生认为是多吃烤炸食物所致，给予《局方》解毒雄黄丸三四服而痊愈，这难道不是针对病因治疗吗？
麻黄根、地骨皮、草乌头（各二两）
将上述药材锉碎成散剂，加入朴硝二两混合均匀。每次用药二两，加水一桶、花椒一合、葱三十根、艾叶一两，共同煎煮十沸，加入米醋一中盏搅拌均匀，去渣滓，坐在温室中，暂且用手巾搭在四肢上，待水温适宜即可洗浴，令汗水透发至面部如珠流下，再坐于室中，或者睡片刻更佳。待汗解之后才穿衣，避风外出，五日后再洗一次，这样洗浴两次后，便服用换骨丹。
Treats Du Jing Chuang (severe genital ulceration) with dripping pus, foul odor, and rotting tissue.
Coptidis Rhizoma (Huanglian), Dendranthemi Flos (Kundonghua) (equal parts)
Grind the above into powder. Wash the affected area with a decoction of Cortex Lycii Radicis (Digupi) and Cnidii Fructus (Shechuangzi), dry with a soft cloth, and apply the medicine mixed with saliva to the lesion. It is strictly forbidden to wash with raw water; this applies to all sores.
Treats Yin Shi Chuang (genital erosion/ulceration).
Polygoni Orientalis Semen (Puhuang) (3 liang), Hydrargyrum (Shuiyin) (1 liang)
Grind evenly. First, soak and wash with pork broth, dry, and sprinkle the powder on the lesion. Another method: for male or female genital ulcers, apply Sulfur (Liuhuang) powder.
The "Li Feng" (Leprosy/Mal de Albers) mentioned in the *Classic* refers to what is called "Da Feng E Ji Lai" (severe wind disease, leprosy) in formula discussions. Although named "wind," it is not necessarily caused by external wind pathogens. Generally, it is mostly due to excessive desires and labor damaging Qi and Blood, causing internal heat to flare up and sweat to leak, while failing to avoid pathogenic wind, cold, and dampness. This allows licentious qi to interfere with Wei Qi (Defensive Qi), causing muscles to swell and bulge. When Qi stagnates, muscles lose sensation; when Ying Qi (Nutritive Qi) becomes turbid and stagnant, heat fails to circulate smoothly, leading to discolored complexion, skin ulceration, and collapse of the nasal bridge. The *Qian Jin Fang* states that this results from one's own unrighteous and vile deeds; although there may be words of repentance, there is no heart of true change, which truly reflects the situation. However, some cases are contagious and not self-inflicted, resulting from carelessness. The transmission of Qi and Blood—is this merely the result of past karma? Investigating the cause, these conditions arise from a combination of non-internal/non-external factors and external pathogens. The manifestations are diverse, as detailed later.
In treating Da Feng, one must deduce the cause. Whether caused by wind-cold-damp-heat, overwork/labor, diet, or contagion, they must not be treated indiscriminately. Dispersing cold-damp and wind-damp, clearing heat, and harmonizing Qi and Blood are distinct treatments. If one universally uses purgative wind medicines, the key to treatment will be missed. I once saw a monk suffering from a disease resembling Bai Lai (white leprosy/vitiligo), who suddenly did not develop sores but shed about one sheng of white skin daily upon waking, like snake shedding. The physician attributed it to excessive consumption of roasted and fried foods and cured him with three or four doses of Jie Du Xiong Huang Wan (Detoxifying Realgar Pill) from the *Ju Fang*. Was this not treating according to the cause?
Ephedrae Radix et Rhizoma (Mahuang Gen), Cortex Lycii Radicis (Digupi), Aconiti Kusnezoffii Radix (Caowutou) (each 2 liang)
Crush the above into coarse powder and mix evenly with Natrii Sulfas (Puxiao) 2 liang. For each dose using 2 liang of the powder, add one bucket of water, one he of Zanthoxyli Fructus (Huajiao), thirty stems of Allii Cepae (Congbai), and one liang of Artemisiae Argyi Folium (Aiyeye). Boil together for ten boils, add one zhong zhan of Oryzae Fructus Acetum (Rimi Cu), mix well, strain, and sit in a warm room. Place towels over the limbs initially. When the water temperature is suitable, bathe until sweat permeates the face like flowing beads. Then sit in the room or sleep for a short while, which is even better. Only dress after the sweat has subsided, avoid wind, and go out. Bathe again after five days. After two such baths, take Huan Gu Dan (Bone-Replacing Pill).
