The *Classic of Medicine* states: Injury to Qi causes pain, and injury to the form (structure) causes swelling. An abscess occurring anterior to the anus and posterior to the scrotum is called Xuantong (Hanging Abscess). Its etiology often stems from the stagnation and anger of the Seven Emotions (Joy, Anger, Worry, Overthinking, Sadness, Fear, Fright), leading to Qi stagnation and blood coagulation; it can also result from forcibly retaining seminal emission or unfulfilled sexual desire. If treatment is not initiated promptly, survival is rarely ensured. Whenever swelling and pain are felt, immediately use several taels of large red-bark Licorice Root (*Gancao*, *Glycyrrhizae Radix et Rhizoma*) with nodes intact, decoct in long-flowing water, and drink on an empty stomach. A method for preparing the medicinal herb is as follows. First, administer Baidu San (Detoxification Powder); if there are alternating chills and fever accompanied by pain, use Xiaochaihu Tang (Minor Bupleurum Decoction) to clear the Liver and resolve heat; if the swelling and pain are severe, indicating Damp-Heat in the Liver Channel, use Longdan Xiegan Tang (Gentian Liver-Draining Decoction). All these formulas take processed Licorice Root (*Zhi Gancao*) as the Sovereign herb. Externally, apply Garlic-Separator Moxibustion; when pus has matured but not ruptured, puncture it with a needle.
Main Formula: Licorice Root (*Gancao*, *Glycyrrhizae Radix et Rhizoma*) (5 qian), Gentian Root (*Longdancao*, *Gentianae Radix*), Angelica Sinensis Tail (*Dangguiwei*, *Angelicae Sinensis Radix*), Honeysuckle Flower (*Jinyinhua*, *Lonicerae Japonicae Flos*), Rehmannia Root (*Shengdihuang*, *Rehmanniae Radix*), Bupleurum Root (*Chaihu*, *Bupleuri Radix*) (each 3 qian), Alisma Tuber (*Zexie*, *Alismatis Rhizoma*), Plantago Seed (*Cheqianzi*, *Plantaginis Semen*), Akebia Stem (*Mutong*, *Akebiae Caulis*) (each 5 fen). Decoct in water and take on an empty stomach.
If urination is difficult/astringent, double the dosage of Plantago Seed, Akebia Stem, and Alisma Tuber, and add Poria (*Fuling*, *Poria*), Phellodendron Bark (*Huangbai*, *Phellodendri Cortex*), and Anemarrhena Rhizome (*Zhimu*, *Anemarrhenae Rhizoma*). For fever, add Coptis Rhizome (*Huanglian*, *Coptidis Rhizoma*) and Green Tangerine Peel (*Qingpi*, *Citri Reticulatae Pericarpium*). For Yin Deficiency, add Siwu Tang (Four Substances Decoction). Xiaochaihu Tang (Formula see *Shanghan Lun* section): Take this formula next, with processed Licorice Root as the main component. If it does not ulcerate, use Bazhen Tang (Eight Treasures Decoction) plus processed Licorice Root. For weakness, take Qingxin Lianzi Yin (Clear Heart Lotus Seed Decoction) (Formula see Bianzhuo section). In all the above formulas, processed Licorice Root is used as the Sovereign herb. If healing is prolonged, take major tonifying medicines, and externally apply Fermented Soybean Cake Moxibustion.
Method for Processing Licorice Root: To treat swelling, pain, and fever of Xuantong, it is effective regardless of whether the abscess has ulcerated or not.
Licorice Root (*Gancao*, *Glycyrrhizae Radix et Rhizoma*) (Red-bark, large ones, use 4 liang, cut into ten segments): Soak thoroughly in one large cup of mountain stream water, slowly roast/dry over low fire, then soak again and dry again, until the water is exhausted. Each dose uses 1 liang, decocted in one bowl of good wine without ash residue, reduced to seven-tenths, strain the dregs, and take on an empty stomach.
The syndrome belongs to the Jueyin Liver Channel. Deficiency of the Yin pathway, Damp-Heat obstruction, turbid Qi sinking downward, flowing into the excretory ducts causes this condition; sometimes abdominal swelling gradually flows into the scrotum, causing failure of fluid differentiation. In severe cases, pus ulcerates and skin sheds, testicles hang exposed, and the scrotum cracks with fluid leakage. With proper management, recovery is possible. First, soothe the Liver and eliminate Dampness; subsequently, nourish Yin and tonify Qi and Blood. Cases involving sexual intercourse after drinking and taking water, where sweat encounters Wind-Cold-Damp-Toxic pathogens which accumulate in the scrotum, should first be treated with Dao Shui Wan (Water-Guiding Pills) twice. After the water pathogen is eliminated and urination returns to normal, use Weiling Tang (Gastrointestinal Ping-Taking Decoction) with doubled Baizhu (*Baizhu*, *Atractylodis Macrocephalae Rhizoma*) and Fuling (*Fuling*, *Poria*).
Main Formula: Angelica Sinensis Tail (*Guiwei*, *Angelicae Sinensis Radix*), Gentian Root (*Longdancao*, *Gentianae Radix*), Rehmannia Root (*Shengdi*, *Rehmanniae Radix*) (each 3 qian), Bupleurum Root (*Chaihu*, *Bulei Radix*), Alisma Tuber (*Zexie*, *Alismatis Rhizoma*), Akebia Stem (*Mutong*, *Akebiae Caulis*), Plantago Seed (*Cheqianzi*, *Plantaginis Semen*), Poria (*Fuling*, *Poria*) (each 1 qian). Add Centipede Grass (*Dengxincao*, *Spargani Rhizoma*) to the top, decoct in water, and take on an empty stomach.
If ineffective, add Phellodendron Bark (*Huangbai*, *Phellodendri Cortex*), Honeysuckle Flower (*Jinyinhua*, *Lonicerae Japonicae Flos*), Gleditsia Spine (*Zaocis Ci*, *Gleditsiae Sinensis Spina*), and Angelica Dahurica Root (*Baizhi*, *Angelicae Dahuricae Radix*). When pus matures but does not rupture, puncture with a needle. Next, take Ginseng, [missing character, likely Astragalus], Angelica Sinensis, Atractylodes Macrocephala, Siwu Tang (Four Substances Decoction) plus Anemarrhena Rhizome (*Zhimu*, *Anemarrhenae Rhizoma*) and Phellodendron Bark (*Huangbai*, *Phellodendri Cortex*). Externally apply Perilla Powder (*Zisu Mo*). Or apply Cedar Charcoal Powder wrapped in Perilla Leaves, while lying supine for recuperation. If healing is prolonged, take major tonifying medicines, and externally apply Prepared Aconite Root Cake Moxibustion.
