囊痈，是指阴囊部位的痈肿。此病归属于足厥阴肝经所主，是由肝肾两经阴液亏虚、湿热之邪下注而形成的。初起时出现肿痛，小便短赤涩痛，应当使用龙胆泻肝汤来清利湿热、解毒，或者选用黄芩、黄连、黄柏、山栀、苡仁、木通、甘草、当归等药物。如果脓液已经形成但小便不通畅，这是热毒壅滞闭塞所致，应先使用托里消毒散，随后用针穿刺排脓；如果脓液已排出但肿痛不减，说明热毒尚未解除，应使用清肝益营汤。此证由阴道（指前阴部位）亏虚、湿热不利所致，因此除湿滋阴的药物不可缺失。若溃破后脓液清稀或量多，或者伤口愈合迟缓，必须使用十全大补汤加入山萸肉、丹皮、泽泻以补益气血；如果身体虚弱却不进行补益，年轻力壮者多会演变为顽固性疾病，年老体弱者多会导致死亡。
还有一种称为“脱囊”的病，发作时寒热交替，阴囊发红、睾丸肿胀，皮肤湿裂，隔一天即变黑，每隔一天腐烂发臭，不出几天阴囊全部脱落，睾丸外露悬垂，形势看似险重，其实并不致命，这都是由湿热下流所致。外敷珍珠散，用白玉膏覆盖，内服四苓散或萆薢分清饮。又有一种称为“水疝”的病，表现为肿痛且皮肤颜色光亮，无发热发红症状，内部积聚水液，适宜用针刺破，引出积水即可安宁，内服五苓散等利湿药物。
悬痈生于肾囊之后、肛门之前，又名海底漏，最难治愈收口。患此病的人，都是极度虚弱之人，由足三阴经亏损，湿热结聚而引发。初生时状如莲子，日久逐渐增大如桃李，红肿疼痛，溃破后轻则形成瘘管，重则气血耗尽，转变为虚劳消耗性疾病的情况很多。治疗方法：初起肿痛且小便赤涩的，属于肝经湿热，主用龙胆泻肝汤；如果伴有肿胀发热，需清肝解毒，用小柴胡汤去掉半夏、人参，加入车前子、黄柏、川芎、当归、甘草；已经溃破的，使用八珍汤加入制甘草、柴胡梢、酒炒黄柏、知母，切不可过度使用寒凉药物，以免损伤胃气；只有制甘草这一味药，名为国老散，不损伤血气，不扰动脏腑，功效甚为迅速，最适合使用。
Nang Yong (Scrotal Abscess) refers to an abscess swelling in the scrotum. This condition is governed by the Foot Jueyin Liver Meridian and arises from Yin deficiency of the Liver and Kidney meridians, with Damp-Heat sinking downward. In the initial stage, presenting with pain and swelling, and dark, scanty, or painful urination, Longdan Xiegan Tang (Gentiana Root Decoction to Drain the Liver) should be used to clear heat, drain dampness, and detoxify, or herbs such as Huangqin (Scutellariae Radix), Lianzi (Coptidis Rhizoma), Huangbai (Phellodendri Cortex), Shanzhi (Gardeniae Fructus), Yiren (Coicis Semen), Mutong (Akebiae Caulis), Gancao (Glycyrrhizae Radix et Rhizoma), and Danggui (Angelicae Sinensis Radix) may be selected. If pus has formed but urination is difficult, this indicates obstruction and closure by Heat-Toxin; Tuoli Xiaodu San (Decoction to Support the Interior and Eliminate Toxins) should be used first, followed by needle drainage. If pus has been discharged but pain and swelling persist, it signifies that Heat-Toxin has not yet resolved; Qinggan Yying Tang (Decoction to Clear the Liver and Nourish the Blood) should be employed. This syndrome results from deficiency of the anterior yin passages and impediment of Damp-Heat; therefore, herbs for draining dampness and nourishing Yin are indispensable. If after ulceration the pus is thin or profuse, or healing is delayed, Shiquan Dabu Tang (Decoction for Tenfold Great Tonification) added with Shanyurou (Corni Fructus), Danpi (Moutan Cortex), and Zexie (Alismatis Rhizoma) must be used to tonify. If deficiency is not treated with tonification, vigorous individuals often develop chronic stubborn diseases, while frail elderly individuals often succumb to death.
Another condition is Tuo Nang (Scrotal Sloughing), which begins with alternating chills and fever, redness of the scrotum, swelling of the testicles, wet cracking of the skin, turning black after two days, and intermittent putrefaction every other day. Within a few days, the entire scrotum sloughs off, leaving the testicles exposed and hanging, appearing critical but actually not fatal; this is caused by Damp-Heat flowing downward. Apply Zhenzhu San (Pearl Powder) externally, cover with Baiyu Gao (White Jade Ointment), and internally administer Siling San (Four-Powder Decoction) or Bixie Tang (Dioscorea Hypoglauca Decoction). There is also a condition called Shui Han (Hydrocele), characterized by pain and swelling with shiny skin color, no heat or redness, and accumulated fluid inside. It is suitable for puncture with a needle to drain the fluid, after which peace is restored; internally, Wuling San (Five-Ingredient Powder with Poria) or similar diuretic herbs for draining dampness should be taken.
Xuan Yong (Hanging Abscess) occurs behind the scrotum and in front of the anus, also known as Haidi Lou (Bottom-of-the-Sea Fistula), and is the most difficult to heal. Patients suffering from this are extremely deficient, with the condition arising from deficiency of the Three Foot-Yin Meridians and accumulation of Damp-Heat. Initially, it resembles a lotus seed; over time, it gradually enlarges to the size of a plum or peach, becoming red, swollen, and painful. After ulceration, mild cases form fistulas, while severe cases exhaust Qi and Blood, often transforming into Lao Zhai (Consumption Disease). Treatment methods: For initial pain and swelling with dark, scanty urination, indicating Liver Meridian Damp-Heat, Longdan Xiegan Tang is the primary prescription. If accompanied by swelling and fever, clear the Liver and eliminate toxins using Xiao Chaihu Tang (Minor Bupleurum Decoction) with Banxia (Pinelliae Rhizoma) and Renshen (Ginseng Radix) removed, and Cheqian (Plantaginis Seed), Huangbai, Xiong (Ligustici Rhizoma et Radix), Guizhi (Cinnamomi Ramulus - *Note: Context implies Danggui/Angelica based on typical formulas, but text says Xiong/Guizhi? Text says "Xiong, Gui". Assuming Xiong = Chuanxiong/Costus Root, Gui = Danggui/Chinese Angelica*), and Gancao added. For already ulcerated cases, use Bazhen Tang (Eight-Treasure Decoction) with processed Gancao, Chaishu Shao (Bupleuri Caudex tip), wine-fried Huangbai, and Zhimu (Anemarrhenae Rhizoma). One must strictly avoid excessive use of cold-natured herbs to prevent damaging Stomach Qi. Only Zhi Gancao (Processed Licorice Root), named Guolao San (State Elder Powder), does not damage Qi and Blood nor disturb the Zang-Fu organs, and its efficacy is rapid; it is most suitable for use.
