证
夫便毒者，生于小腹下，两腿合缝之间。其毒初发，寒热相作，腿间肿起疼痛是也。夫肾为作强之官，
所藏者，精与志也。男女大欲，不能以直遂其志，故败精搏血，留聚中途，而结为便毒矣。况其所，乃精
气所出入之道路也。或触物而动心，或梦寐而不泄，既不得偶合阴阳，又不能忘情息念，故精与血，交滞
而肿结也。初起慎不可用寒凉之药，恐气血愈结而不得宣散，反成大患。
惟当发散寒气，清利热毒，使精血宣畅，自然愈矣。
阴头肿痛生疮者，名为下疳也。乃督、任、冲三脉之属，督脉属阳，任脉属阴，冲脉属厥阴。阳
脉主气，阴脉主血，皆由气血大热，有毒有风，故生此疮。其疮一生，则便毒、厉风疮、次第而发
也。先宜升麻葛根汤发出，其发后；服凉血解毒丸即愈，不必用轻粉之类。
下疳疮，乃男子玉茎生疮，皆由所欲不遂，或交接不洁，以致邪毒浸溃，发成疮毒。日久不愈，或成
便毒，或损烂阳物，多致危笃。又鱼口疮，妒精疮，皆其类也。俗云疳疮未已，便毒复来生也。
妒精疮者，由妇人阴中先有宿精，因而交接，虚热熏蒸，即成此疾。初发在阴头如粟，拂之即痛甚，
两日出清脓，作臼孔，蚀之太痛。妇人有生于玉门内，正似疳蚀疮，不痛为异耳。

【病症论述】
所谓便毒，是生长在小腹下方、两腿内侧接缝处的疾病。其初发时，表现为寒热交替发作，大腿间肿胀疼痛。肾被称为“作强之官”，所储藏的是精与志。男女之间强烈的欲望若不能顺遂实现，导致败精与血搏结，停滞在半途，从而凝结成便毒。况且该部位，正是精气出入的道路。有时因接触外物而动心，或梦中遗精而未泄，既不能通过阴阳交合来调和，又不能忘记情欲平息念头，因此精与血相互阻滞而肿胀凝结。初起时千万不可使用寒凉药物，恐怕气血更加凝结而不能宣散，反而酿成大祸。只应当发散寒气，清利热毒，使精血宣畅，自然就会痊愈。
阴头（阴茎头部）肿痛生疮的，称为下疳。这属于督脉、任脉、冲脉这三条经脉的范畴。督脉属阳，任脉属阴，冲脉属厥阴。阳脉主气，阴脉主血，皆因气血大热，兼有毒邪和风邪，所以生出这种疮疡。一旦生出此疮，便毒、厉风疮等便会依次发作。初期宜用升麻葛根汤透发，发过后；再服用凉血解毒丸即可痊愈，不必使用轻粉之类的药物。
下疳疮，是男子玉茎（阴茎）生疮，都是由性欲不得满足，或性交不洁，导致邪毒浸渍溃烂，发成为疮毒。日久不愈，有的变成便毒，有的损伤腐烂阳物，多导致病情危重。又有鱼口疮、妒精疮，都属于这一类。俗话说是疳疮未好，便毒又复发。
妒精疮，是由于妇人阴道内先有残留的精液，因而进行性交，虚热熏蒸，就形成这种疾病。初发时在阴头如粟米大小，触碰即剧痛，两天后流出清脓，形成臼孔状，侵蚀时非常疼痛。妇女中有的在玉门（阴道口）内生长，正像疳蚀疮一样，只是不痛为不同之处。

[Discussion on Symptoms]
The so-called "Bian Du" (Perineal Abscess) is a disease occurring in the lower abdomen, between the inner seams of the two thighs. Upon initial onset, it presents with alternating chills and fever, along with swelling and pain in the thigh region. The Kidney is referred to as the "Official of Strength and Endurance," storing Essence (Jing) and Will (Zhi). When intense sexual desires in men and women cannot be fulfilled directly, defeated Essence and Blood contend and stagnate midway, condensing into Bian Du. Moreover, this area serves as the pathway for the exit and entry of Qi and Essence. Sometimes, contact with external objects stirs the mind, or nocturnal emissions occur without release; since Yin and Yang cannot be harmonized through intercourse, nor can emotional thoughts be extinguished, Essence and Blood become mutually obstructed, leading to swelling and condensation. At the initial stage, cold-natured medicines must strictly be avoided, lest Qi and Blood become further condensed and unable to disperse, thereby causing greater disaster. One should only employ methods to disperse cold pathogens and clear heat-toxins, allowing Essence and Blood to circulate freely, which will naturally lead to recovery.
Swelling, pain, and ulceration of the glans penis are named "Xia Gan" (Chancre). These belong to the governing vessel (Du Mai), conception vessel (Ren Mai), and penetrating vessel (Chong Mai). The Du Mai belongs to Yang, the Ren Mai to Yin, and the Chong Mai to Jueyin. Yang vessels govern Qi, and Yin vessels govern Blood; all arise from excessive heat in Qi and Blood, combined with toxic and wind pathogens, thus generating such sores. Once this sore appears, Bian Du and Li Feng Chuang (Leprosy-like Sores) will subsequently develop. Initially, Shengma Gegen Tang (Cimicifugae et Puerariae Decoction) should be used to vent the pathogen; after venting, Liang Xue Jie Du Wan (Cooling Blood and Resolving Toxin Pill) should be taken for complete recovery. Medicines like Qian Fen (Calomel) are unnecessary.
Xia Gan Chuang (Chancre Ulcer) refers to ulcers on the male organ (Yu Jing), caused by unfulfilled sexual desire or unclean intercourse, leading to the infiltration and erosion of evil toxins, resulting in ulcerative sores. If not healed over time, it may transform into Bian Du or cause damage and rotting of the genitalia, often leading to critical conditions. Yu Kou Chuang (Fish Mouth Ulcer) and Du Jing Chuang (Jealousy Essence Ulcer) are also of this category. Folklore states that Chancre recurs when Bian Du reappears.
Du Jing Chuang arises when residual semen remains in the female vagina prior to intercourse; subsequent sexual activity causes deficiency-heat to steam and ferment, forming this ailment. It initially appears on the glans like millet grains; touching it causes severe pain. After two days, clear pus flows out, forming hole-like erosions that are extremely painful when eroded. In women, it may grow inside the Yu Men (vaginal opening), resembling Chancre erosion, except that it is painless.
