泉州有客卢元钦患大风，惟鼻根未倒。属五月五日，官取蚺蛇胆欲进，或言肉可以治风，
遂取一截蛇肉食之，三五日渐可，百日平复。盖蛇之奔腾疾走，皆风象也，故为逐风之鳞，
或嫌其毒而唾之，不知医之所取者，妙在其毒也。《易》曰∶同气相求。有此蛇毒，方能就
彼疠毒，如水流湿，火就燥，各从其类耳。《内经》曰∶衰之以属。正是此意。
疠风眉发堕落者，取皂角刺九蒸九晒为末，每服酒下二钱。久服眉发再生，肌肤悦润，
眼目倍明。
叙曰∶喉者，气之关隘也，通则利，塞则害，无问其标本而当急治焉者也。今考八方于
后，皆古人已试之程规，触类而通之，则活人之机 矣。
升麻、连翘（各六分），生地黄、黄芩（各四分），当归、苏木、全蝎、地龙、黄芪、黄连（各三分），桔梗（五分），甘草（一钱半），人参（二分），胡桐泪（一分），桃仁（三枚），麝香（少许），虻虫（一枚，去掉翅膀和足，微炒），水蛭（二枚，炒至烟尽）。
补气泻荣，是治疗疠风的精妙旨意。卫气虚弱而邪气侵袭，所以用人参、黄芪、甘草来补益正气。营血败坏而形成疠风，所以用虻虫、水蛭、桃仁、苏木来消除瘀血。全蝎、地龙引导诸药到达风湿结聚的部位。至于麝香，它能通利关窍，无处不到。升麻、连翘、桔梗入气分以解除热邪。黄连、黄芩入脏以清泄气分之热。当归、地黄入血分以调和新生之血。至于胡桐泪，用它来清除大毒之热，又足以杀灭疠风之虫并消除顽固肿胀。
泉州有一位名叫卢元钦的客人患有大风病（麻风病），只有鼻根没有塌陷。适逢五月五日，官府采集蚺蛇胆想要进献，有人说蛇肉可以治疗风病，于是取了一段蛇肉吃下，三五天逐渐好转，一百天后完全康复。大概蛇的奔腾疾走，都是风象的表现，所以它是逐风的鳞类动物。有人嫌弃它有毒而唾弃它，却不知道医学所利用的，正是它的毒性。《易经》说：同气相求。有了这种蛇毒，才能去攻彼疠毒，就像水往湿处流，火向燥处燃，各自遵循同类相从的道理。《内经》说：用具有某种属性的药物来衰减疾病。正是这个意思。
对于疠风导致眉毛头发脱落的人，取皂角刺经过九次蒸、九次晒后研成粉末，每次用酒送服二钱。长期服用可使眉毛头发再生，肌肤润泽，眼睛格外明亮。
序言说：喉部，是气息通行的关隘，通畅则顺利，阻塞则有害，无论病因标本如何，都应当紧急治疗。现在考证以下八方，都是古人已经验证过的规范方法，触类旁通，那么救人的机巧也就在其中了。
Shengma (Rhizoma Cimicifugae), Lianqiao (Forsythiae Fructus) (each 6 fen); Shengdihuang (Radix Rehmanniae Preparata), Huangqin (Scutellariae Radix) (each 4 fen); Danggui (Angelicae Sinensis Radix), Sumu (Sappan Lignum), Quanxie (Buthus martensii), Dilong (Pheretima), Huangqi (Astragali Radix), Huanglian (Coptidis Rhizoma) (each 3 fen); Jiegeng (Platycodonis Radix) (5 fen); Gancao (Glycyrrhizae Radix et Rhizoma) (1.5 qian); Renshen (Ginseng Radix) (2 fen); Hutonglei (Tear of Hu Tong) (1 fen); Taoren (Persicae Semen) (3 seeds); Shexiang (Moschus) (a small amount); Mengchong (Asellus) (1 piece, remove wings and feet, lightly stir-fried); Shuizhi (Hirudo) (2 pieces, stir-fry until smoke disappears).
This is a formula by Li Dongyuan for treating Lífēng (Leprosy/Mal de Albers).
Tonifying Qi and purging Ying (Nutritive Blood) represents the profound principle in treating Lífēng. When Wei (Defensive) Qi is deficient and pathogens invade, Renshen (Ginseng Radix), Huangqi (Astragali Radix), and Gancao (Glycyrrhizae Radix) are used to tonify Qi. When Ying (Nutritive) blood deteriorates leading to Lífēng, Mengchong (Asellus), Shuizhi (Hirudo), Taoren (Persicae Semen), and Sumu (Sappan Lignum) are employed to resolve blood stasis. Quanxie (Buthus martensii) and Dilong (Pheretima) guide the various herbs to sites where wind-dampness has accumulated. As for Shexiang (Moschus), it benefits the orifices and reaches everywhere. Shengma (Rhizoma Cimicifugae), Lianqiao (Forsythiae Fructus), and Jiegeng (Platycodonis Radix) enter the Qi level to resolve heat. Huanglian (Coptidis Rhizoma) and Huangqin (Scutellariae Radix) enter the Zang organs to clear Qi-level heat. Danggui (Angelicae Sinensis Radix) and Shengdihuang (Radix Rehmanniae Preparata) enter the Blood level to regulate newly generated blood. Regarding Hutonglei (Tear of Hu Tong), it is used to eliminate severe toxic heat and is sufficient to kill parasites causing Lífēng and remove stubborn swelling.
In Quanzhou, a guest named Lu Yuanqin suffered from Dafeng (severe Leprosy), with only his nasal bridge remaining intact. It was the fifth day of the fifth lunar month, and the government was collecting bile from Python molurus (Ranshe) to present as tribute. Someone suggested that snake meat could treat wind diseases, so he took a segment of snake meat and ate it. Within three to five days, he gradually improved, and after one hundred days, he fully recovered. The vigorous running and leaping of snakes are manifestations of Wind; thus, they are considered scales that expel wind. Some disdain them due to their toxicity, not realizing that medicine utilizes precisely this toxicity. The *I Ching* states: "Like energies seek each other." With this snake toxin, one can address the leprous toxin, just as water flows to wet places and fire moves toward dry materials, each following its own kind. The *Neijing* states: "Reduce it with substances belonging to its category." This is exactly the meaning.
For cases of Lífēng where eyebrows and hair have fallen out, take Gaojiaoci (Spina Gleditsiae) subjected to nine steaming and nine sun-drying processes, grind into powder, and take 2 qian with wine per dose. Long-term consumption promotes regrowth of eyebrows and hair, renders skin supple and lustrous, and sharpens vision.
Preface: The throat is the passageway for Qi; patency brings benefit, obstruction brings harm. Regardless of whether the condition is root or branch, urgent treatment is required. The following eight formulas are examined here, all being established protocols tested by ancients. By applying these principles analogously, the means to save lives shall be realized.
