癞之为证，方书罕载。愚初亦以为犹若疥癣不必注意也。自戊午来奉天诊病，遇癞证之剧者若干，有
患证数年，费药资甚巨不能治愈者，经愚手，皆服药数剂全愈。后有锦州县戎××患此证，在其本地服药无
效，来奉求为延医，服药六剂即愈。隔三年，其证陡然反复，先起自面上，状若顽癣，搔破则流黄水，
其未破之处，皮肤片片脱落，奇痒难熬，歌哭万状。在其本处服药十余日，分毫无效，复来奉求为延医。其脉
象洪实，自言心中烦躁异常，夜间尤甚，肤愈痒而心愈躁，彻夜不眠，若再不愈，实难支持。遂为疏方，用
蛇蜕四条，蝉蜕、僵蚕、全蝎、甘草各二钱，黄连、防风各三钱，天花粉六钱，大枫子十二粒，连皮捣碎。为
其脉洪心躁，又为加生石膏细末两半。煎汤两茶盅，分两次温饮下。连服三剂，面上流黄水处皆结痂，其有
旧结之痂皆脱落，瘙痒烦躁皆愈强半，脉之洪实亦减半。遂去石膏，加龙胆草三钱。服一剂，从前周身之似有
似无者，其癞亦皆发出作瘙痒。仍按原方连服数剂，全愈。至方中之药，诸药皆可因证加减，或用或不
用，而蛇蜕则在所必需，以其既善解毒（以毒攻毒），又善去风，且有以皮达皮之妙也。若畏大枫子有毒，
不欲服者，减去此味亦可。
梦遗之病，最能使人之肾经虚弱。此病若不革除，虽日服补肾药无益也。至若龙骨、牡蛎、萸肉、金樱

臭剥抱水诸品，虽为麻醉脑筋之药，而少用之实可以安靖脑筋。
若再与龙骨、牡蛎诸药同用，则奏效不难矣。愚素有常用之方，爰录于下∶
龙骨一两， 牡蛎一两，净萸肉二两，共为细末，再加西
药臭剥十四瓦，炼蜜为百丸。每临睡时服七丸，服至两月，病可永愈。
The condition known as "Lai" (leprosy-like skin disease or severe dermatosis) is rarely recorded in medical texts. I initially also considered it similar to scabies or tinea, and thus not worthy of special attention. Since the year Wuwu (1918), when I practiced medicine in Fengtian (now Shenyang), I encountered several severe cases of Lai. Some patients had suffered for years, spent enormous sums on medication without cure, but under my treatment, all were completely cured after taking only a few doses of medicine. Later, a Mr. Rong from Jinzhou County suffered from this condition; having taken local medications with no effect, he came to Fengtian seeking my medical care. After taking six doses, he was cured. Three years later, his condition suddenly relapsed, starting on the face. The lesions resembled stubborn tinea; when scratched open, they exuded yellow fluid, while the unbroken skin peeled off in patches. The itching was unbearable, causing extreme distress, even manifesting as erratic weeping and laughing. He took over ten days of local medication with no effect and returned to Fengtian for further treatment. His pulse was surging and full (Hong Shi). He reported extreme mental restlessness, worse at night; the more his skin itched, the more agitated he felt, keeping him awake all night. He stated that if not cured soon, he would not be able to endure it. Therefore, I prescribed a formula using Snake Slough (Shetui) four pieces, Cicada Slough (Chantui), Silkworm (Jiangcan), Whole Scorpion (Quanxie), and Licorice Root (Gancao) each two qian, Coptis Rhizome (Huanglian) and Saposhnikovia Root (Fangfeng) each three qian, Trichosanthes Root (Tianhuafen) six qian, and 12 seeds of Ailanthus Seed (Dafengzi), crushed together with their skins. Given his surging pulse and mental agitation, I added one and a half liang of fine powder of Raw Gypsum (Sheng Shigao). The mixture was decocted into two teacups of liquid, to be taken warm in two divided doses. After taking three consecutive doses, the areas on the face exuding yellow fluid formed crusts, old crusts fell off, and both itching and agitation were reduced by more than half; the surging quality of the pulse also decreased by half. Thus, I removed the Gypsum and added Gentian Root (Longdancao) three qian. After one dose, the vague, almost imperceptible lesions all over his body emerged fully, accompanied by itching. Continuing with the original formula for several more doses resulted in complete recovery. Regarding the herbs in the formula, most can be modified according to the syndrome, used or omitted as needed, but Snake Slough is essential because it is excellent at resolving toxicity (using toxicity to combat toxicity) and dispelling wind, and possesses the subtle efficacy of "treating the skin with the skin." If one fears the toxicity of Ailanthus Seed and wishes to avoid it, this herb may be omitted.
Nocturnal emission (Meng Yi) is a condition that most readily causes weakness of the Kidney Meridian. If this disease is not eradicated, taking kidney-tonifying medicines daily will be of no benefit. Although astringent substances such as Dragon Bone (Longgu), Oyster Shell (Muli), Cornus Fruit (Yurou), and Cherokee Rose Fruit (Jinyingzi) often show efficacy when taken, there is ultimately no absolute guarantee of success. This is a disorder characterized by lightness and reckless movement of the brain/mind (Naojin). Only Western medicines such as Potassium Bromide (Choubao Shui), which are sedatives/anesthetics for the nervous system, can truly calm the mind when used in small amounts. If combined with Longgu and Muli, therapeutic effects can be achieved readily. I have a commonly used prescription, which I record below:
Dragon Bone (Longgu) one liang, Oyster Shell (Muli) one liang, Purified Cornus Fruit (Jing Yurou) two liang, all ground into fine powder. Add fourteen grains (wa) of Western medicine Potassium Bromide (Choubao). Form into 100 pills using refined honey. Take seven pills just before going to sleep. After two months of administration, the disease can be permanently cured.
