下疳（一种发生于生殖器部位的疮疡），是由邪淫和欲火郁滞而形成的。其成因有三种：一是男子情欲萌动，阴茎勃起，淫火炽盛却未能发泄，导致败精浊血流滞中途，凝结而成肿块，这是第一种情况；二是因妇人阴器内有瘀积的精浊之气未清理干净，与之性交，导致淫精传染感染而形成，这是第二种情况；三是……使用热性药物，……多导致火邪郁结未能发散而形成，这是第三种情况。男子因情欲萌动、火邪郁结的病症，初起时必然出现尿道涩痛、小便溺痛，随后流出黄浊的败精，阴茎逐渐受损，严重时出现肿痛腐烂，治疗法则应当疏利肝肾的邪火，如八正散、清肝导滞汤之类的方剂。妇人因阴器不洁，初起时先从皮肤肿胀光亮，严重时长得像水晶一样，皮肤破裂流水，肿痛日益加重，瘙痒麻木时常发作，治疗应当解毒祛风，如龙胆泻肝汤兼平胃散合并使用。男女房事所伤，蕴毒所致，初起时阴茎痒痛，坚硬呈紫色，疙瘩逐渐生成，腐烂逐渐发生，血水淋漓，不时勃起，治疗应当泻火解毒，如黄连解毒汤、芦荟丸之类的方剂。外用银粉散、珍珠散、人中白散选用。又有先患梅毒（时疮），误用熏条擦药，导致毒气结聚于此的，详见结毒门，不在此类推论。
初起时不红不肿，睡眠中阴茎不勃起，玉茎轻微受损，小便通畅自利的为轻证。已经形成但微热微肿，皮色光亮，小便赤色，更兼有白浊的为平证。已经损伤但肉色红活，没有坚硬肿胀，小便不疼痛，大便不通秘的为可治之证。初起时小便淋漓不尽，随后损伤阳物，坚硬作痛，腐烂逐渐扩大的为险证。已经形成腐溃并向内攻陷，伤损玉茎，颜色紫暗无脓，疼痛如针刺的为重症。

Xiagan (Chancre, a type of ulcer occurring on the genitalia) is formed by the stagnation of pathogenic lust and desire-fire. Its origins are threefold: First, when a man's sexual desire stirs, his penis becomes erect, and the lust-fire rages without release, causing spoiled essence and turbid blood to stagnate midway, condensing into a swelling; this is the first cause. Second, due to uncleaned stagnant essence and turbid qi in the female genitalia, intercourse leads to the transmission of infectious essence, resulting in the condition; this is the second cause. Third, the use of... hot-natured medicines... often causes fire-pathogens to stagnate without dispersing, leading to the condition; this is the third cause. For men suffering from symptoms of desire-stirring and fire-stagnation, the initial stage invariably presents with urethral astringency and dysuria, followed by the discharge of yellow, turbid spoiled essence. The penis gradually deteriorates, and in severe cases, swelling, pain, and rotting occur. The treatment principle should be to drain and regulate the pathogenic fire of the Liver and Kidney, using formulas such as Bazheng San (Eight-Herb Rectifying Powder) or Qinggan Daozhi Tang (Clear Liver and Guide Out Stagnation Decoction). For women caused by unclean genitalia, the initial stage presents with skin swelling that is bright and shiny, resembling crystal in severity. When the skin breaks, fluid leaks out, swelling and pain increase daily, and itching and numbness occur intermittently. Treatment should focus on resolving toxicity and dispelling wind, such as combining Longdan Xiegan Tang (Gentian Liver-Draining Decoction) with Pingwei San (Calm the Stomach Powder). For injuries caused by sexual practices in both men and women, resulting from accumulated toxins, the initial stage presents with penile itching and pain, hardness, purple discoloration, gradual formation of nodules, progressive rotting, dripping of bloody fluid, and frequent erections. Treatment should involve purging fire and resolving toxicity, using formulas such as Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) or Lushui Wan (Aloe Pill). Externally, select from Yinfen San (Silver Powder Powder), Zhenzhu San (Pearl Powder), or Renzhongbai San (Human Tooth Ash Powder). There are also cases where Chancre (Syphilis/Time Plague) was initially contracted, but due to the mistaken use of fumigation strips and topical applications, toxins became knotted here; these are detailed in the Knotted Toxin Section and are not included in this general classification.
If at the initial stage there is no redness or swelling, the penis does not erect during sleep, the jade stem suffers only slight damage, and urination is smooth and self-regulating, it is a mild case. If already formed but with slight heat and swelling, bright skin color, reddish urine, accompanied by white turbidity, it is a moderate case. If tissue has been damaged but remains red and vibrant, without hard swelling, urination is painless, and defecation is not constipated, it is a treatable case. If at the initial stage urination is dribbling, subsequently damaging the yang organ, which becomes hard and painful, with rotting gradually spreading, it is a dangerous case. If already formed with putrefaction and ulceration attacking inward, damaging the jade stem, presenting with purple color and no pus, and pain like needle pricks, it is a severe case.
