身半以上，天之阳也。病则气受之，气受之则上病，故眉落、鼻坏而颅破也。高巅之上，

赤芍、胡麻，皆养血清气于驱风燥湿之队者也。地龙者，泥蟠之物，湿土所化也，故能引诸
药以就湿；白花、乌梢者，奔腾之类，风动之象也，故能君诸药以驱风，此《易》所谓云从

上为末，每服二钱，熟酒调下无时。尝坐于浴室汤中一时许，服药神良。
疠风，此方常获奇效。
疠风攻凿气血，木石不能获效者，非其类也。故用血气之属，能主风者以治之。蝉蜕主

治疠风，所谓衰之以属也。然必坐于浴室汤中服药者，所以开泄腠理，使邪气有所出尔。
白花蛇、乌梢蛇（用酒浸泡一整夜）、地龙（去除泥土，各三两）、当归（用酒炮制）、苍术（用米泔水浸泡七天）、木鳖子（去掉外壳）、细辛、蔓荆子、白芷、赤芍药、威灵仙、天麻、天门冬、川芎、甘菊花、何首乌、紫参、荆芥穗、沙参、石菖蒲、胡麻（炒制）、苦参、不灰木、草乌、炙甘草、白蒺藜、定风草（即天麻的幼苗）、木贼（以上药材各一两）。
将上述药材共同研磨成粉末，每次服用五钱，饭后用酒调服，多喝一些效果更好。
对于病程长久的大风病（麻风病），导致眉毛脱落、鼻梁塌陷崩坏、额头颅骨肿胀破溃的情况，此方主治。
身体上半部分，属于天的阳气。患病时气机受邪，气机受邪则病位在上，所以出现眉毛脱落、鼻子崩坏和头颅破溃的症状。在高耸的头顶部位，只有像定风草等气味轻清的药物，才能上行至头部，能够驱散风邪，能够胜湿。至于不灰木、石菖蒲、草乌、苍术，则可以直接治疗湿邪。而苦参、紫参、沙参、何首乌，都是用来解毒的。当归、甘草、天门冬、赤芍药、胡麻，都是在祛风燥湿的药队中，起到养血清气作用药物。地龙是潜伏在泥土中的生物，由湿土所化生，所以能引导其他药物趋向湿邪；白花蛇、乌梢蛇属于奔腾跳跃的动物，具有风动的意象，所以能作为君药引领其他药物驱散风邪，这正是《易经》所说的“云从龙，风从虎”的道理。
蝉蜕、地龙（炒制）、白僵蚕（炒制）、全蝎（炒制，各七个）、凌霄花（半两）。
将上述药材研磨成粉末，每次服用二钱，随时可用熟酒调服。曾经有人在浴室热水中坐约一个时辰后服药，效果神奇良好。
疠风侵蚀破坏气血，连草木金石类药物都无法见效时，必须使用动物类药材来治疗。蝉蜕主治风热，地龙主治风湿，僵蚕和全蝎主治风毒，凌霄花主治被风邪败坏的血分。这五种药物都有微毒，用它们来治疗疠风，这就是所谓的“以同类之品削弱病势”的方法。然而一定要坐在浴室热水中服药，是为了开泄腠理（皮肤毛孔），使邪气有出路排出体外。
Baihua She (Deinagkistrodon acutus, White-flower Snake), Wushao She (Zaocys dhumnades, Black-striped Snake) (soaked in wine for one night), Dilong (Pheretima aspergillum, Earthworm) (free from soil, 3 liang each), Danggui (Angelicae Sinensis Radix, Dong Quai) (prepared with wine), Cangzhu (Atractylodis Rhizoma, Atractylodes Rhizome) (soaked in rice washing water for seven days), Mubiezi (Strychni Semen, Nux Vomica Seed) (shell removed), Xixin (Asari Radix et Rhizoma, Asarum Root), Manjingzi (Viticis Semen, Vitex Fruit), Baizhi (Angelicae Dahuricae Radix, Dahurian Angelica Root), Chishao (Paeoniae Radix Rubra, Red Peony Root), Weilingxian (Clematidis Radix et Rhizoma, Clematis Root), Tianma (Gastrodiae Rhizoma, Gastrodia Rhizome), Tiandongdong (Ophiopogonis Radix, Ophiopogon Root), Chuanxiong (Ligustici Chuanxiong Rhizoma, Szechwan Lovage Rhizome), Gan Juhua (Chrysanthemi Flos, Chrysanthemum Flower), Heshouwu (Polygoni Multiflori Radix, Fo-ti Root), Zishen (Scutellariae Barbatae Herba, Scutellaria Barbata Herb), Jingjiesui (Schizonepetae Spica, Schizonepeta Spike), Shashen (Adenophorae Radix, Ladybell Root), Shichangpu (Acori Tatarinowii Rhizoma, Sweet Flag Rhizome), Huma (Sesami Fructus Usticus, Stir-fried Sesame Seed), Kushen (Sophorae Flavescentis Radix, Sophora Root), Buhui Mu (Asbestos, Non-burning Wood), Caowu (Aconiti Kusnezoffii Radix, Kusnezoff Monkshood Root), Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata, Prepared Licorice Root), Baijili (Tribuli Fructus, Tribulus Fruit), Dingfeng Cao (Tianma's seedling, Dingfeng Grass), Muzei (Equiseti Herba, Horsetail Herb) (1 liang each).
Grind all the above ingredients into powder. Take 5 qian per dose, mixed with wine after meals; drinking more is advisable.
This formula is indicated for long-standing大风 (Feng Da, severe leprosy/mal de Meleda) that has not healed, characterized by falling eyebrows, collapse of the nasal bridge, and swelling and ulceration of the forehead and skull.
The upper half of the body belongs to the Yang Qi of Heaven. When diseased, the Qi is affected; when Qi is affected, the disease manifests upwards, hence the symptoms of eyebrow loss, nasal collapse, and skull ulceration. At the high peak (head), only substances like Dingfeng Cao, which have light and clear flavors, can ascend to the head, dispel wind, and overcome dampness. Meanwhile, Buhui Mu, Shichangpu, Caowu, and Cangzhu can directly treat dampness. Kushen, Zishen, Shashen, and Heshouwu are used to detoxify. Danggui, Gancao, Tiandongdong, Chishao, and Huma nourish blood and clear qi within the group of wind-dispelling and dryness-resolving herbs. Dilong is a creature that wriggles in mud, transformed from damp earth, so it can guide other drugs towards dampness; Baihua She and Wushao She belong to creatures that leap and bound, representing the image of moving wind, so they act as sovereign drugs to lead others in dispelling wind. This is what the *I Ching* (Book of Changes) refers to as "clouds follow the dragon, wind follows the tiger."
Chanqiao (Cicada Slough), Dilong (Stir-fried), Baijiangcan (Bombyx Batryticatus, Silkworm) (Stir-fried), Quanxie (Scorpio, Scorpion) (Stir-fried, 7 each), Lingxiao Hua (Campsis Grandiflora Flos, Trumpet Vine Flower) (0.5 liang).
Grind the above into powder. Take 2 qian per dose, mixed with warm wine at any time. Once, sitting in a bathhouse hot water for about an hour before taking this medicine yielded miraculous results.
For Li Feng (Li Feng, Leprosy), this formula often achieves remarkable effects.
When Li Feng attacks and destroys Qi and Blood, and herbal or mineral remedies fail, animal-derived substances must be used. Chanqiao treats Wind-Heat, Dilong treats Wind-Damp, Jiangcan and Quanxie treat Wind-Toxicity, and Lingxiao Hua treats blood damaged by wind. These five substances all possess slight toxicity; using them to treat Li Feng exemplifies the principle of "using similar nature to weaken the pathogen." However, one must sit in the bathhouse hot water while taking the medicine to open the Couli (skin pores) and allow the pathogenic factors to exit.
