用带节的粉甘草四两，长流水一碗，将甘草炙烤后浸泡于水中，待水完全被吸收后研成细末，加入少许皂角灰，分为四次服用，用汤药调服并一次性喝完，效果显著。另一个方子：甘草节、白芷、黄连各等分，切碎，用水煎煮。如果痈肿已经破溃，用龙骨、枯白矾、赤石脂外敷。有一人上部咳嗽下部肾痈破溃，用玄参、炒黄柏、青黛、犀角、山楂、甘草节、神曲、麦麸（此处原文“麦”疑为麦麸或麦芽，依语境暂译）、桃仁、连翘，研成细末制成丸剂。治疗便毒的方子：山栀、大黄、乳香、没药、当归（各五分），栝蒌仁（二钱），代赭石（一钱），以上药材作为一剂煎煮。另一个方子：木鳖子、大黄、栝蒌仁、草龙胆、桃仁，浓煎，露天放置一夜，清晨温服。又一个方子：白僵蚕、槐花，共同研成细末，用酒调服。有一个方子加酒制大黄。又一个方子：蠡实根三寸，与生姜等分研细，用热开水调匀，空腹服用。又一个方子：大黄、牡蛎各二钱半，栝蒌一个去皮，甘草去皮，以上切碎作为一帖，用水煎煮，空腹服用。
热邪深入血分的极期，初起感觉时先用青皮、甘草节，之后应当养血。起初腿部肿胀用人参、黄芪、茯苓各二钱，栝蒌仁四十八粒，做成两帖，加入竹沥，趁热饮用。环跳穴疼痛不止，要防止发生附骨痈（详见《医要》）。
铁圈散治疗痈疽肿毒：乳香、没药（各半两），大黄、黄连、黄柏、南星、半夏、防风、羌活、皂角、甘草节、草乌、阿胶（另入，以上各一两）。以上药材研成细末，用醋调成膏状，在沙石器中用火熬至黑色，用鹅毛翎蘸取敷于患处。寒证用热法，热证用寒法。疔疮根深，必须用针刀旋转刺破，在疮头上敷蟾酥，然后再用药饵。野菊研成细末，用酒调饮至醉，醒来后疼痛停止、热邪消除，不必去除疔根也能自愈。隔皮取脓法治各种肿毒：驴蹄（炒至一两，切细），荞麦面（炒一两），白盐（半两），草乌（四钱，去皮）。以上研成细末，用水调匀，捏成饼子，用慢火烤至微黄色，去除火毒，再研成细末，用醋调成膏状，用白纸摊开贴敷患处，水分自然从毛孔排出，肿胀自然消退。治疗天蛇头（手指末端红肿如蛇头），用野落苏（即黄丝草）、金银花藤（即羊儿藤）、五叶紫、葛藤、天荞麦，切碎各十分之一，用好米醋浓煎，先熏后洗。又一个方子，用人粪混合黄泥捣烂，裹在患处即可安宁。治疗天火丹（丹毒的一种），用神曲和泥土炒后研细，香油调敷。又一个方子，雉鸡毛和鹅毛烧成灰，香油调敷都可以。治疗一切疔疮，紫梗菊的根、茎、叶、花皆可，研碎取汁，滴入口中饮用。白蜡具有收敛作用（已见《医要》），治疗痈疽，用一层露蜂房，在里面放入白矾，安置在石上，用火熔化飞过（煅烧）后研成细末，油调敷之。另一个方子，粪浸甘草大治肿毒，其详细内容在冬温条下。凡是治疗痈疽应当分清经络，六阳经、六阴经，有多气少血的，有多血少气的，不可一概而论。少阳经多气少血，肌肉难以生长，理应预防驱毒，利药也不宜轻用。我的堂叔，思虑过多导致神劳，年近五十，左臂外侧红肿如栗子，我说不要轻视，先给人参浓汤，得到微微出汗才好，给服了数十帖才停止。十多天后，遇到大风拔起树木，疮上出现一条红线，绕背抵住右肋，我说必须大量人参汤加上川芎、白术的补剂，给他服用了两个月才安定。李兄的儿子三十岁，接连遭遇忧患，且好色又有劳累，左腿外侧下方一处红肿如栗子。一个医生给服承气汤两帖泻下，又一个医生教以解毒汤泻下，我于是诊视说脉象大实，后来果然死亡。臀部位于小腹之后，又在下部，这是阴中之至阴，其道遥远，其位偏僻，虽然太阳经多血，但气难久运，血也罕到，中年以后生发的，必须预先补益。如果没有积补的功效，祸患多在疮成结痂之后，或者半年间才发病。粗劣的医生不察，可能导致失手，谨慎戒除。治疗痈肿，应当区分肿疡而施治，不可急于使用五香连翘汤等药物。未溃破之前，托里透脓兼以消散；已溃破之后，补气补血。用手按压肿胀处，发热则有脓，不发热则无脓。
Use four liang of licorice root (Gancao, 甘草) with nodes, and one bowl of long-flowing water. Roast the licorice root, soak it in the water until the water is completely absorbed, then grind it into a fine powder. Add a small amount of soap pod ash (Zaojiao Hui, 皂角灰). Divide into four doses. Mix with decoction and take all at once; this is highly effective. Another prescription: Licorice root nodes (Gancao Jie, 甘草节), Angelica dahurica (Baizhi, 白芷), and Coptis chinensis (Huanglian, 黄连) in equal parts. Coarsely crush, decoct in water. If the abscess has ruptured, apply dragon bone (Longgu, 龙骨), calcined alum (Kubai Fan, 枯白矾), and red kaolin (Chishizhi, 赤石脂) externally. A case of a patient with upper cough and lower kidney abscess rupture: Use Scrophularia ningpoensis (Xuanshen, 玄参), roasted Phellodendron amurense (Huangbai, 黄柏), Indigo naturalis (Qingdai, 青黛), rhinoceros horn (Xijiao, 犀角 - *note: modern substitute often used*), Hawthorn fruit (Shanzha, 山楂), licorice root nodes, Medicated leaven (Shenqu, 神曲), wheat bran (Mai Fu Pi, 麦麸 - *interpreted from context "Mai"*), peach kernel (Taoren, 桃仁), and Forsythia suspensa (Lianqiao, 连翘). Grind into powder and make pills. Prescription for inguinal abscess (Biandu, 便毒): Gardenia jasminoides (Shanzhi, 山栀), Rhubarb (Dahuang, 大黄), Frankincense (Ruxiang, 乳香), Myrrh (Moyao, 没药), Angelica sinensis (Danggui, 当归) (each 5 fen), Trichosanthes kirilowii seed (Gualou Ren, 栝蒌仁) (2 qian), Hematite (Daizheshi, 代赭石) (1 qian). Prepare as one dose for decoction. Another prescription: Momordica charantia seed (Mubiezi, 木鳖子), Rhubarb, Trichosanthes kirilowii seed, Gentiana scabra (Caolongdan, 草龙胆), peach kernel. Decoct strongly, leave exposed overnight, and take warm early in the morning. Another prescription: Silkworm cocoon (Baijiangcan, 白僵蚕), Sophora flower (Huaihua, 槐花), grind together into powder, mix with wine and take. One variation adds wine-processed Rhubarb. Another prescription: Semen Phaseoli (Lishi, 蠡实) root, three cun, equal part fresh ginger, grind finely, mix with hot water, take on an empty stomach. Another prescription: Rhubarb, Oyster shell (Muli, 牡蛎) (each 2.5 qian), one Trichosanthes kirilowii peeled, licorice root peeled. Coarsely cut as one packet, decoct in water, take on an empty stomach.
When heat reaches the extreme stage in the blood level, initially use Citrus reticulata green peel (Qingpi, 青皮) and licorice root nodes. Later, nourish the blood. For initial leg swelling, use Ginseng (Renshen, 人参), Astragalus membranaceus (Huangqi, 黄芪), Poria cocos (Fuling, 茯苓) (each 2 qian), and forty-eight Trichosanthes kirilowii seeds. Make two packets, add bamboo sap (Zhulü, 竹沥), and drink while hot. If pain persists at the Huantiao acupoint (Huantiao, 环跳), guard against the formation of deep-seated abscess (Fugu Yong, 附骨痈) (see detailed explanation in *Yiyao*).
Tiequan San (Iron Ring Powder) treats carbuncles, sores, and toxic swellings: Frankincense, Myrrh (each half liang), Rhubarb, Coptis chinensis, Phellodendron amurense, Arisaema erubescens (Nanxing, 南星), Pinellia ternata (Banxia, 半夏), Saposhnikovia divaricata (Fangfeng, 防风), Notopterygium incisum (Qianghuo, 羌活), soap pod, licorice root nodes, Aconitum carmichaelii lateral root (Caowu, 草乌), Donkey-hide gelatin (Ejiao, 阿胶) (added separately, each one liang above). Grind into powder, mix with vinegar to form a paste. Boil in a clay pot over fire until black. Apply to the affected area with a goose feather. For cold conditions, use heat application; for heat conditions, use cold application. For deep-rooted carbuncles (Dingchuang, 疔疮), must use needle and knife to rotate and break open. Apply toad venom (Chansu, 蟾酥) on the head of the sore, then use herbal medicine internally. Wild chrysanthemum ground into powder, mixed with wine and drunk until intoxicated. Upon waking, pain stops and heat dissipates; no need to remove the carbuncle root, it will heal itself. Method of extracting pus through the skin for various toxic swellings: Donkey hoof (roasted one liang, finely cut), buckwheat flour (roasted one liang), white salt (half liang), Aconitum carmichaelii lateral root (four qian, peeled). Grind into powder, mix with water, knead into cake shape. Slowly roast until slightly yellow, remove fire toxicity, grind into powder, mix with vinegar to form paste. Spread on white paper and apply to the affected area. Moisture exits naturally through hair follicles, swelling recedes spontaneously. For treating "Heaven Snake Head" (tip of finger swelling), use wild eggplant (Ye Luosu, 野落苏, i.e., Huangsi Cao), honeysuckle vine (Jinyinhua Teng, 金银花藤, i.e., Yang'er Teng), Wuyezicai, kudzu vine, Tianqiaomai. Cut finely, each one-tenth part. Decoct strongly with good rice vinegar. Fumigate first, then wash. Another prescription: Mix human feces with yellow mud, pound it, wrap around the affected area for relief. For treating "Heaven Fire Dan" (erysipelas), stir-fry yeast (Qu, 曲) with soil, grind finely, mix with sesame oil and apply. Another prescription: Pheasant feathers and goose feathers burned to ash, mix with sesame oil and apply. For treating all carbuncles, roots, stems, leaves, and flowers of Purple-stemmed Chrysanthemum can be used. Crush and extract juice, drip into mouth and drink. White wax has astringent properties (seen in *Yiyao*). To treat carbuncles and sores, place one layer of honeycomb (Lufengfang, 露蜂房) containing alum on a stone. Melt and calcine with fire, grind into powder, mix with oil and apply. Another prescription: Licorice root soaked in manure greatly treats toxic swellings; details are under the Winter Warmth section. When treating carbuncles and sores, one must differentiate by meridians. The Six Yang meridians and Six Yin meridians have variations of abundant qi and scarce blood, or abundant blood and scarce qi; they cannot be treated uniformly. Shaoyang meridian has abundant qi and scarce blood; muscles are difficult to regenerate. It is appropriate to prevent and expel toxins; purgative medicines should not be used lightly. My cousin, who suffered from excessive mental labor, was nearly fifty years old. There was red swelling like a chestnut on the outer side of his left arm. I said do not underestimate it. First give strong Ginseng decoction. Getting slight sweating is good. After taking dozens of packets, it stopped. More than ten days later, during a storm that uprooted trees, a red line appeared on the sore, circling the back to the right hypochondrium. I said large doses of Ginseng decoction plus Ligusticum wallichii (Xiong, 川芎) and Atractylodes macrocephala (Zhu, 白术) tonics are necessary. He took them for two months and recovered. Brother Li's son, thirty years old, had experienced continuous worry and hardship, indulged in lust, and worked hard. There was red swelling like a chestnut on the lower outer side of his left leg. One doctor gave Chengqi Tang (Big Order Downward Decoction) for two doses to purge. Another doctor taught to use Jiedu Tang (Detoxification Decoction) to purge. I examined him and said the pulse was large and excess. He subsequently died. The buttocks are located behind the lower abdomen and below, which is the utmost yin within yin. The pathway is distant, the position is remote. Although the Taiyang meridian has abundant blood, qi is difficult to circulate for long, and blood rarely reaches there. For those developing sores after middle age, preventive tonification is necessary. Without accumulated tonification efforts, disaster often occurs after the sore forms a scab, or manifests after half a year. Incompetent doctors fail to observe this, leading to mistakes. Be cautious and vigilant. When treating carbuncles and swellings, treatment should be differentiated based on whether it is a swelling or ulcer. Do not hastily use Wuxiang Lianqiao Tang (Five Fragrant Forsythia Decoction). Before rupture, support the interior and disperse; after rupture, tonify qi and blood. Press the swollen area with hand; if hot, there is pus; if not hot, there is no pus.
