治疗疠风，即所谓的大风恶疾，也就是癞病。虽然名为“风”，但未必都是由外感风邪引起。大率多是因嗜欲过度、劳力耗气，导致汗出泄气，又不躲避邪风，使得淫邪之气与卫气相互干扰，从而导致肌肉麻木不仁；劳损之气使体液浑浊，导致热气不利，所以皮肤生疮溃烂，鼻梁塌陷毁坏，或者自行产生麻木不仁的症状，这极有可能是由极其卑劣的行为所致。日久之后，可能出现全身白皮脱落，像蛇蜕皮一样。
以上方：用桑枝灰一斗，用热水淋取汁液，用来洗头面。接着用大豆和绿豆浆加入熟水，每三天洗一次澡，每天洗一次脸。
治疗大风恶疾，双眼昏花，近在咫尺也分辨不出人物，眉毛头发自然脱落，鼻梁崩塌倒塌，肌肤生疮如同苔藓，病情危急似乎无法挽救。此方有特效。
以上方：用皂角刺三斤，用炭火长时间蒸制，晒干后研为细末，用浓煎的大黄汤送服一匕（量词，约指一勺或特定剂量），服用十天左右，眉毛头发重新生长，肌肤恢复。
治疗因多痰炙爆（此处疑为原文传抄错误或特定术语，结合上下文可能指体内积热成毒或痰火炽盛）而成此疠风。用茶清送服三四次，见效。（该方见大方科积热类。）
浴法：
麻黄根、地骨皮、草乌头（各二两）
以上药材切碎散开，研磨朴硝二两，均匀混合。每次用药一两，加水一桶，花椒一合、葱三十茎、艾叶一两，共同煎煮至透面（此处疑为“透”字漏字，意为煎煮透彻或至一定浓度），进行洗浴。
九肋鳖甲、海蜈蚣（细锉碎。各二两）
以上药材用盐泥密封固济，待干后，用火煅烧至存留二分药性，研为细末。巴豆半两，去皮膜，顺着纹理研磨。青州枣七枚，去核。
将枣肉与巴豆一起研烂如泥状，加入前两种药的细末，研磨均匀，用醋煮糊制成丸药，大小如绿豆。每次服用七丸，体质虚弱者加服四到五丸。用温的腌菜汁送服。等到排出脓血烂鱼肠样的恶物时，立即停药。如果服用三两剂后仍未排便排毒，再加服三丸。随后服用遇仙丹。
人参、紫参（各一两）、苦参（二两）、白僵蚕（去掉嘴部，二两）
以上药材研为细末，用面糊制成丸药，大小如梧桐子。每次服用三十丸，用温盐水吞服，饭前服用，每日两次。随后服用疏风散。
To treat Leprosy (Lifeng), also known as the Great Wind malignant disease, which is Lepra. Although named "Wind," it is not necessarily caused by external wind pathogens. Generally, it is mostly due to excessive desires and labor consuming Qi, leading to sweating and leakage of Qi, failing to avoid evil winds, causing turbid Qi to interfere with Defensive Qi (Wei Qi). This results in insensitivity of muscles; consumption Qi causes turbidity of body fluids, leading to obstruction of heat, thus skin sores ulcerate, the nasal bridge collapses and is destroyed, or one spontaneously becomes insensitive. These are extremely vile conditions resulting from base acts. Over time, white skin may peel off all over the body, resembling snake shedding.
The above prescription: Use ten dou of ash from mulberry branches, pour hot water through it to extract the juice, and use it to wash the head and face. Next, use paste made from soybeans and mung beans mixed with boiled water. Bathe once every three days, and wash the face once a day.
To treat the Great Wind malignant disease, where both eyes are dim, unable to distinguish people even at close range, eyebrows and hair fall out naturally, the nasal bridge collapses, skin sores appear like moss, and the condition seems critical and incurable. This prescription is highly effective.
The above prescription: Use three jin of Gleditsia Sinensis Spina (Zao Jiao Ci), steam for a long time over charcoal fire, dry in the sun, and grind into powder. Take one bi (a small spoonful) with strong decoction of Rheum Palmatum (Dahuang). Within ten days of administration, eyebrows and hair will regrow, and skin will recover.
For leprosy caused by excessive phlegm and internal heat toxicity (textual ambiguity, likely referring to accumulation of heat/phlegm): Take three to four doses with clear tea liquor, effect observed. (See the formula under the category of Accumulated Heat in the Major Department.)
Bathing method:
Radix Ephedrae Caudicis (Mahuang Gen), Cortex Lycii (Digupi), Radix Aconiti Lateralis Preparata (Caowutou) (each two liang).
Chop these herbs into pieces, grind two liang of Natrii Sulfas (Puxiao), and mix evenly. For each dose, use one liang of the herb mixture, one bucket of water, one he of Zanthoxylum Bungeanum (Huajiao), thirty stems of Allium Fistulosum (Cong), and one liang of Artemisia Argyi Folium (Aiye). Decoct together until fully penetrated, then bathe.
Testudo Chiwensis Carapax et Plastron (Jiule Biejia), Pseudoscorpion (Hai Wugong) (finely chopped. Each two liang).
Seal these with salt mud, let dry, and calcine over fire retaining only two parts of their nature. Grind into powder. Semen Crotonis Tiglii (Badou) half liang, remove skin and membrane, grind along the grain. Seven Qingzhou dates, remove pits.
Mash the dates and Badou together into a paste-like consistency, add the powders of the previous two ingredients, grind uniformly, and make pills using vinegar-boiled flour paste, sized like mung beans. Take seven pills per dose; for those with deficiency, add four to five pills. Take down with warm brine juice. Stop when foul matter resembling pus, blood, or rotten fish intestines is discharged. If no discharge occurs after three doses, add three more pills. Subsequently take Yuxian Dan.
Ginseng Radix (Renshen), Scutellaria Barbata Herba (Zican), Sophorae Flavescentis Radix (Kushen), Bombyx Batryticatus (Bai Jiangcan) (remove mouthparts, two liang).
Grind all into powder, make pills with flour paste, sized like Sophora japonica seeds (Wutongzi). Take thirty pills per dose, swallow with warm salt water, before meals, twice daily. Subsequently take Shufeng San.
