在肛门与外生殖器之间发生的痈毒，称为悬痈。医书中对此记载不多，世间也很少有人知道。初发时只觉得很痒，肿块大小像松子，逐渐增大如莲子，四十多天后才红肿如胡桃。一旦破溃，大小便都会从此处排出，这就无法治愈了。其药用横纹大甘草一两，截成约三寸长的段，取山涧向东流的清水一大碗（井水、河水不可用）。用甘草蘸水，在文火和武火之间交替慢煮，不可性急，必须煮三个时辰，直到水尽为止。掰开甘草看其中湿润透心，才算煮好。然后用无灰酒两碗再煮，等到剩下一半时，作为一次服用，温服。起初可能不见明显疗效，二十天左右才会消退。未破溃者不会破溃，可以保持平安，即使再加服也无害。兴化太守姚康朝正患此痈，众医生束手无策，服用两剂后痊愈。
吴大以前曾用泥土修补善神庙，后来建房屋时从梯子上摔下，腰部伤势非常紧急。梦见神灵来说：“你过去曾救过我，我不敢忘记。”于是传授给他乳香饮的方子。该方用酒浸虎骨、败龟甲、牛膝、萆薢、续断、乳香七味药。醒来后能记得，立即叫儿子买药恭敬地服用，十天痊愈。（出自《己志》）
当时康祖担任广德县令，对张王非常尊敬，全家不吃猪肉。后来下身患有疾病，稍有好转，左侧乳房又生痈肿，接着胸臆间又结出核块，大如拳头，坚硬如石，拖延半年，各种药物都无法施用。不久牵掣手臂腋部直达肩部，疼痛特别剧烈，急忙到王祠祈祷。梦中听到声音说：“若要安宁，只用姜自然汁制作香附服用即可。”梦醒后叫儿子检查本草，发现这两味药的治疗证候相符，访求医者张棣也说有理。于是用香附去毛，用姜汁浸泡一夜，研为粉末，每次二钱，米汤调服。才服几剂，疮脓流出，肿硬逐渐消退，从此痊愈。（出自《庚志》）
靖康二年春天，京城瘟疫盛行，有异人在斋舍写下方子，凡是因瘟疫导致肿胀的人，服用无不有效。其方：黑豆二合，炒至香熟；甘草二寸，炙黄。用水两盏煎至一半，时时少量饮用。（同上）
The carbuncle and toxic swelling occurring between the anus and the external genitalia is named Xuan Yong (Hanging Carbuncle). It is rarely recorded in medical books, and few people in the world know of it. At the initial onset, there is only a sensation of intense itching; the nodule is initially as large as a pine nut, gradually enlarging to the size of a lotus seed. After more than forty days, it becomes red and swollen like a walnut. Once it ruptures, both urination and defecation will occur from this opening, making it incurable. The medicinal material used is large licorice root with transverse striations, one tael, cut into segments approximately three cun long. One bowl of clear water from a mountain stream flowing eastward is taken (well water or river water must not be used). The licorice is dipped in water and slowly decocted alternating between mild and strong heat; impatience must be avoided. It must be boiled for three shichen (six hours) until the water is completely evaporated. The licorice is broken open to check if the center is moist and thoroughly penetrated, which indicates it is properly prepared. Then, two bowls of unadulterated wine are added, and it is boiled again until half remains. This constitutes one dose, taken warm. Initially, there may be no obvious effect; it takes about twenty days for the swelling to subside. If it has not ruptured, it will not rupture, ensuring safety; additional doses are harmless. Yao Kangchao, the prefect of Xinghua, suffered from this carbuncle. While many physicians held their hands in helplessness, he recovered after taking two doses.
Wu Da had previously used mud to repair the temple of the God of Goodness. Later, while constructing a house, he fell from a ladder and severely injured his waist. He dreamed that the deity came to him and said, "You once saved me in the past; I dare not forget." Thus, he was instructed to use the formula for Rushang Yin (Frankincense Decoction). The formula uses seven ingredients: tiger bone soaked in wine, tortoise shell (from a dead turtle), Achyranthes Root (Niuxi, 牛膝), Dioscorea Hypoglauca Rhizome (Bixie, 萆薢), Dipsacus Root (Xuduan, 续断), and Frankincense (Ruxiang, 乳香). Upon waking, he could remember the prescription and immediately ordered his son to purchase the herbs and respectfully take them. He recovered in ten days (Recorded in 'Ji Zhi').
At that time, Kang Zu served as the magistrate of Guangde and showed great reverence for Zhang Wang, with his entire family abstaining from eating pork. Subsequently, he suffered from an ailment in the lower body. After slight improvement, a carbuncle reappeared on the left breast, followed by the formation of nodules in the chest and epigastrium region, as large as fists and hard as stones. Half a year passed, and various medicines proved ineffective. Soon, the pain radiated from the arm and axilla to the shoulder, causing extreme suffering. He urgently prayed at the shrine of Zhang Wang. In the dream, he heard a voice say, "If you wish for peace, simply use fresh ginger juice to process Cyperi Rhizoma (Xiangfu, 香附) and take it." Upon waking, he called his son to consult the Materia Medica and found that the therapeutic indications for these two substances matched. He consulted the physician Zhang Di, who also agreed it was reasonable. Thus, Cyperi Rhizoma was de-haired, soaked overnight in fresh ginger juice, ground into powder, and two qian were taken each time, mixed with rice water. After only a few doses, pus drained from the sore, and the swelling and induration gradually subsided, leading to recovery (Recorded in 'Geng Zhi').
In the spring of Jingkang Year 2, a severe epidemic broke out in the capital city. A mysterious person wrote a prescription on the wall of a rest house. Anyone suffering from swelling due to the epidemic took it without exception, achieving efficacy. The formula consists of: black beans, two he, stir-fried until fragrant and cooked; licorice root, two cun, honey-fried until yellow. Decoct in two zhan of water until reduced to half. Sip frequently in small amounts (Ibid.).
