夫阴疮者，大概有三等∶一者湿阴疮；二者妒精疮；三者阴蚀疮，又曰下疳疮。盖湿疮
由肾经虚弱，风湿相搏，邪气乘之，搔痒成疮，浸淫汗出，状如疥疮者是也；妒精者，由壮
年精气盈满，久旷房室，阴上生疮，赤肿作害，烦闷痒痛者是也；阴蚀疮者，由肾脏虚邪，
热结下焦，经络痞涩，气血不行，或房劳洗浴不洁，以致生疮，隐忍不医， 肿尤甚，由疮
在里，措手无方，疼痛注闷，或小便如淋，阴丸肿痛是也。或经十数日，溃烂血脓，肌肉侵
蚀，或血出不止，以成下疳。若身体壮热，烦渴恶寒，宜急治之，以大豆甘草汤渍之，渍毒
汤者洗浴之；服五香连翘汤、漏芦汤等疏之，更以截疳抵圣散干糁之，四畔用磨风膏温润之
，后以将护忌慎之。渴不止者，服竹叶黄 汤；大便软者，宜服托里茯苓调治之。夫如是，
则无不瘥矣。
夫时毒者，为四时邪毒之气而感之于人也。其候发于鼻、面、耳、项、咽喉，赤肿无头
结核有根，令人增寒发热，头痛肢体痛，甚者恍惚不宁，咽喉闭塞。人不识者，将为伤寒，
便服解药，一、二日，肿气益增方悟，始召疮医。原夫此疾，古无方论，世俗通为丹瘤，病
家恶言时毒，切恐传染。考之于经曰∶人身忽然变赤，状如涂丹，谓之丹毒。此风热恶毒所
为，谓之丹瘤，与夫时毒特不同耳！盖时毒者，感四时不正之气，初发状如伤寒，五、七日
之间乃能杀人，治之宜精辨之。先诊其脉，滑、数、浮、洪、沉、紧、弦、涩，皆其候也。
盖浮数者，邪气在表也；深涩者，邪气深也。认是时毒瓦斯实之人，急服化毒丹以攻之，热实
以五利大黄汤下之；其有表证者，解毒大黄汤以发之；或年高气软者，五香连翘汤主之。又
于鼻内 通气散，取十余嚏作效；若 药不嚏者，不可治之；如嚏出脓血者，治之必愈。如
左右看病之人，日日用 药嚏之，必不传染，切须忌之。其病患每日用嚏药三、五次，以泄热
毒，此治时毒之良法也。经三、四日不解者，不可大下，犹宜和解之，服犀角连翘散之类；
至七、八日，大小便通利，头面肿起高赤者，可服托里散、黄 散，宜针镰砭割出血，泄其
毒瓦斯，十日外不治自愈也。此病若五日以前，精神昏乱，咽喉闭塞，语声不出，头面不肿，食
不知味者，必死之候，治之无功矣。然而此疾，有阴有阳，有可汗，有可下。尝见粗工但云热
毒，只有寒药，殊不知病有微甚，治有逆从，
阴疮这一病症，大致可以分为三类：一是湿阴疮；二是妒精疮；三是阴蚀疮，也称为下疳疮。
湿阴疮是由于肾经虚弱，风湿二气相互搏结，邪气乘虚侵入，导致搔抓后形成疮疡，浸淫流汗，症状如同疥疮一样；妒精疮，是因为壮年时期精气充盈，但长期禁绝房事，导致阴部生疮，红肿疼痛，伴有烦闷、瘙痒和疼痛；阴蚀疮，是由于肾脏虚损受邪，热邪结聚于下焦，经络阻滞涩滞，气血运行不畅，或者因为房劳过度、洗浴不洁，从而导致生疮，如果隐忍不治疗，肿胀会更加严重，由于疮疡在体内深处，难以处理，出现疼痛且伴有闷胀感，或者小便像淋证一样，睾丸肿痛等。有的经过十几天，溃烂流脓血，肌肉被侵蚀，或者出血不止，从而形成下疳。如果身体高热，烦躁口渴，恶寒，应当紧急治疗，用大豆甘草汤浸泡患处，或用渍毒汤进行洗浴；内服五香连翘汤、漏芦汤等以疏通排毒，再用截疳抵圣散干粉撒敷，四周涂抹磨风膏以温润保护，之后注意调护和禁忌。如果口渴不止，服用竹叶石膏汤（注：原文“黄 ”推测为石膏或黄连，结合语境及常见方剂，此处依原文留白或通用理解，但在翻译中需忠实原文，故译为“竹叶黄[缺字]汤”，实际临床常指竹叶石膏汤或类似清热生津方，此处严格按原文“竹叶黄 汤”处理）；大便软者，适宜服用托里茯苓散来调理。像这样，就没有不能治愈的。
时毒，是由四时不正的邪毒之气感染人体所致。其症状发作于鼻子、面部、耳朵、颈部、咽喉部位，红肿无头，结核有根，使人怕冷发热，头痛肢体疼痛，严重的会出现神志恍惚不安，咽喉闭塞。人们如果不认识这个病，误以为是伤寒，就服用解表药，一两天后，肿胀更加严重才醒悟，这才召请外科医生诊治。追溯这种疾病，古代没有专门的方论，世俗人通常称之为丹瘤，病人家属忌讳说“时毒”二字，担心传染。考证医经记载：人身突然变红，状如涂丹，称为丹毒。这是由风热恶毒引起的，称为丹瘤，与时毒完全不同！所谓时毒，是感受四时不正之气，初发时症状像伤寒，在五到七天之间可能致死，治疗应当精细辨别。先诊察脉象，滑、数、浮、洪、沉、紧、弦、涩，都是其征候。其中浮数脉，表示邪气在体表；深沉涩脉，表示邪气深入。确认是时毒邪气实盛的人，急服化毒丹以攻逐邪气，热实证用五利大黄汤泻下；如果有表证的，用解毒大黄汤发散；如果是年老气弱的人，主用五香连翘汤。另外在鼻内吹入通气散，取打喷嚏十余次作为见效标准；如果用药后不打喷嚏的，属于不可治之症；如果打出脓血的，治疗必定痊愈。如果陪同看病的人，每天用药粉吹鼻打喷嚏，必定不会被传染，必须忌避这一点。病患每天使用嚏药三到五次，以泄出热毒，这是治疗时毒的好方法。经过三、四天病情未缓解的，不可以猛烈泻下，仍然适宜和解，服用犀角连翘散之类的药物；到了七、八天，大小便通畅，头面肿胀高起发红，可以服用托里散、黄芪散，适宜用针镰砭石割破出血，以泄出毒气，十天以后不治也会自愈。这个病如果在五天以前，精神昏乱，咽喉闭塞，说不出话，头面不肿，吃东西不知道味道，这是必死的征候，治疗也没有功效了。然而这个病，有阴证阳证之分，有可发汗的，有可泻下的。曾见庸医只说是热毒，只用寒凉药物，却不知道病有轻重深浅，治疗有逆治从治的区别。
Yin sores (Yin Chuang) can be generally categorized into three types: one is dampness-related yin sore; the second is jealousy-induced sore (Du Jing Chuang); and the third is erosive yin sore, also known as chancre (Xia Gan Chuang).
Dampness-related yin sore arises from weakness in the Kidney Meridian, where wind-dampness combats each other, allowing pathogenic factors to invade. Scratching leads to sores that exude fluid and sweat, resembling scabies (Jie Chuang). Jealousy-induced sore occurs when a young man with abundant essence and qi abstains from sexual activity for a long time, causing sores to grow on the genitals, characterized by redness, swelling, harm, irritability, itching, and pain. Erosive yin sore results from deficiency and pathogenic invasion of the Kidneys, with heat binding in the Lower Jiao, causing obstruction and stagnation of meridians and non-circulation of Qi and Blood. It may also stem from excessive sexual activity or unclean bathing. If left untreated due to endurance, swelling becomes severe. Since the sore is deep within, it is difficult to treat, leading to pain, distension, symptoms resembling strangury (Lin Zheng), and swelling and pain of the testicles. After ten days or more, it may ulcerate with bloody pus, erode muscle tissue, or cause continuous bleeding, forming a chancre. If accompanied by high fever, irritability, thirst, and aversion to cold, urgent treatment is required. Soak the area with Da Dou Gan Cao Tang (Soybean and Licorice Decoction) or bathe with Zi Du Tang (Poison-Soaking Decoction). Internally administer Wu Xiang Lian Qiao Tang (Five-Spice Forsythia Decoction) or Lou Lu Tang (Euphorbia Decoction) to dredge and drain. Apply Jie Gan Di Sheng San (Chancre-Cutting and Sainthood-Reaching Powder) dry to the lesion, and use Mo Feng Gao (Wind-Rubbing Ointment) around the periphery to moisten and warm. Subsequently, observe dietary and lifestyle precautions. For persistent thirst, take Zhu Ye Huang [missing character] Tang (Bamboo Leaf and [Missing] Decoction); for soft stools, take Tuo Li Fu Ling San (Support-Interior Poria Powder) for regulation. In this manner, recovery is assured.
Shi Du (Seasonal Toxin) is caused by the infection of pathogenic toxic qi from the four seasons. Its manifestations appear on the nose, face, ears, neck, and throat, presenting as redness and swelling without a head, with nodules rooted deeply. It causes chills, fever, headache, and limb pain. Severe cases lead to mental confusion, restlessness, and throat obstruction. Unaware of the condition, people often mistake it for Tai Yang Disease (Tai Yang Bing) and take exterior-releasing medicines. After one or two days, the swelling increases, at which point they realize their error and summon a surgeon. Historically, there were no specific formulas or discussions for this disease in ancient texts. The common people usually call it Dan Liu (Dan Nodule). Patients' families dislike the term "Shi Du" due to fear of contagion. Medical classics state: sudden reddening of the body, looking like painted cinnabar, is called Dan Du (Erysipelas). This is caused by wind-heat and evil toxins, termed Dan Liu, which is distinctly different from Shi Du! Shi Du results from contracting abnormal qi of the four seasons. Initially, it resembles Tai Yang Disease, but can be fatal between the fifth and seventh days. Treatment requires precise differentiation. First, diagnose the pulse: Slippery (Hua), Rapid (Shu), Floating (Fu), Surging (Hong), Deep (Chen), Tight (Jin), Wiry (Xian), and Choppy (Se) are all indicators. A Floating-Rapid pulse indicates pathogenic factors in the Exterior; a Deep-Choppy pulse indicates deep-seated pathogens. For patients with substantial Shi Du pathogenic qi, urgently administer Hua Du Dan (Toxin-Transforming Pill) to attack the pathogen. For excess heat, use Wu Li Da Huang Tang (Five-Benefits Rhubarb Decoction) to purge downward. For those with Exterior syndromes, use Jie Du Da Huang Tang (Detoxifying Rhubarb Decoction) to release the exterior. For the elderly with weak Qi, primarily use Wu Xiang Lian Qiao Tang. Additionally, blow Tong Qi San (Vent-Qi Powder) into the nostrils until more than ten sneezes occur, indicating efficacy. If the patient does not sneeze after medication, the condition is incurable. If pus and blood are expelled via sneezing, the treatment will surely succeed. Attendants should use the powder daily to induce sneezing to prevent contagion. The patient should use the sneezing powder three to five times daily to vent heat and toxin; this is an excellent method for treating Shi Du. If unresolved after three or four days, do not purge severely; instead, harmonize using Xi Jiao Lian Qiao San (Rhinoceros Horn and Forsythia Powder). By the seventh or eighth day, if urination and defecation are free and the head/face are swollen, red, and elevated, administer Tuo Li San (Support-Interior Powder) or Huang [missing character] San (Astragalus Powder). Prick the area with needles, lancets, or bi stones to bleed out and vent the toxic qi. After ten days, it may heal spontaneously. If, before the fifth day, the patient exhibits mental confusion, throat obstruction, inability to speak, lack of head/face swelling, and loss of taste, it is a death omen, and treatment will be futile. However, this disease has Yin and Yang aspects, and treatments may involve sweating or purging. I have seen incompetent physicians attribute it solely to heat toxin and use only cold medicines, failing to understand that diseases vary in severity and treatments must follow either counteracting or following principles.
