上采叶，研为滓。每用不限多少，纳瓷瓶中，入水，用文武火浓煎，临热入好无灰酒与
药汁相半，再煎十数沸，滤滓，时时服之。留滓焙干，碾、罗为细末，酒煮面糊，为丸梧桐子
大，每服三十丸，空心温酒下。丸药俟疾稍退，可以常服，盖其力轻甚故也。
预防痈疽方 服此药可以终身无此疾。

疾。
案∶以上各方，不见于诸论中，今总集之，附于诸论之后。
脑疽不可灸，引其气一上，痰涎、脓血并起上攻，倾人性命急于反掌，但当急灸三里穴
并气海，渐渐服凉胸膈、化血之药，人可小安。此说载《通神方论》。脑疽、咽喉生疽，古法皆
不治之证，此灸法引毒瓦斯归下，其理颇长。得此疾者，岂可坐受其毙，当信而用之。
栝蒌散 治妇人乳痈奶劳，神效（今俗呼奶劳，即此疾之渐）。
栝蒌（一个。去皮，焙、研为末，急用则烂研。子多者有力） 当归（净洗，去芦，焙细，半
两） 甘草（半两。细锉，生用） 通明没药（一分，别研） 乳香（一钱，别研）
上用无灰酒三升，同于银、石器中，慢火熬取一升清汁，分作三服，食后良久服。如有
奶劳，便服此药，可绝病根。如毒己成，能化脓为黄水；毒未成，即于大小便中通泄。疾甚，再
合服，以退为妙。妇人乳疽方虽多，独此一方神效无比，万不失一。
按∶以上二方，一治脑疽，一治乳疽，皆与背疽无涉，以其为李氏之书，故并附于此。
治疗轻微的痈疖，在肿块结聚但尚未化脓时，不可使用膏药贴敷，而应用药物涂抹，使病灶内部自行消散。每次取新鲜鹿角尖，放入砂钵中，与老米醋（即陈醋）或当时俗称的“黄子醋”浓磨成浆，时常用鹅毛蘸取涂抹于痈疖四周，中间留出一个孔口，待干燥后再涂，一两天后病灶即可在体内消散。每当感觉有轻微痈疖疼痛、发热时，便使用生甘草节，不经过炙烤或烘焙，利用日晒干燥；若无阳光，可置于笼盖上用微火烘干，碾成细末，用热酒调服二三钱，连续服用数次，疼痛和发热症状即可停止。
治疗痈疽尚未结成硬块，以及气血凝滞、肿胀结成块状者，将吴茱萸轻微炒制，碾成细末，用鸡蛋清调和后涂抹，效果神妙！病情较轻者适宜使用此法。
治疗痈疽发背的神效方：
金银花（又名忍寒草）
采集其叶片，研磨去渣。每次用量不限多少，放入瓷瓶中，加入水，用文火和武火交替浓煎，趁热加入优质无灰酒，使药汁与酒各占一半，再煮沸十余次，滤去药渣，时时服用。留下的药渣焙干，碾碎并过筛成细末，用酒煮面糊制成梧桐子大小的丸剂，每次服用三十丸，空腹时用温酒送下。丸药可在病情稍退后常服，因为其药力轻缓的缘故。
预防痈疽方：服用此药可以终身不得此病。
绵黄芪（七两。挑选像箭杆一样笔直、质地柔软的药材使用，芦头和叉枝不用。一半生用，细细切碎，焙干；一半切成寸长段，捶扁，用蜜水浸润湿润，盛放在瓦器中盖好，在饭甑上蒸三次，取出焙干，再切碎）
粉甘草（去掉节和皮，取净重一两半，将其中一半生用，细细切碎、焙干；另一半炙至黄色，切碎、焙干）
以上两味药，碾成细末。每次服用二钱，早晨和中午，用白开水煎服，平时应作为汤药服用；夜间饮酒时，第一杯酒用药粉调服。如果平日能如此常服，终身不会患痈疽之疾。
案语：以上各方，未见于其他医论中，现总集于此，附于诸论之后。
脑疽不可施灸，否则引动气机上逆，导致痰涎、脓血一并上攻，危及生命的速度快如反掌之间。只应当紧急灸治足三里穴和气海穴，渐渐服用清凉胸膈、化解瘀血的药物，患者方可稍得安宁。此说记载于《通神方论》。脑疽、咽喉生疽，古法皆视为不治之证，此灸法能将毒瓦斯引向下行，其道理颇为深远。得了这种病的人，岂能坐以待毙，应当相信并使用此法。
栝蒌散：治疗妇人乳痈及奶劳（当今俗称奶劳，即此病的初期阶段），效果神妙。
栝蒌（一个。去皮，焙干后研为末，急用时则烂研。种子多者药效更强）
当归（洗净，去芦头，焙干后切细，半两）
甘草（半两。细细切碎，生用）
通明没药（一分，单独研细）
乳香（一钱，单独研细）
以上药物用无灰酒三升，同置于银器或石器中，用慢火熬取一升清汁，分作三次服用，饭后良久服用。如有奶劳症状，立即服用此药，可断绝病根。如果毒邪已成，能使脓液化为黄水排出；毒邪未成，则通过大小便通泄排出。病情严重者，再次合服，以病情减退为妙。治疗妇人乳疽的方剂虽多，唯独此一方神效无比，万无一失。
For treating minor carbuncles and furuncles (inflammatory skin diseases), when the swelling is formed but not yet suppurated, plaster applications should not be used. Instead, apply medicinal paste to allow the lesion to resolve internally. Take fresh deer horn tips, place them in a mortar, and grind them thickly with aged rice vinegar or the common "Huangzi vinegar" of the time. Frequently use a goose feather to brush the mixture around the periphery of the carbuncle or furuncle, leaving a central opening. Reapply when dry; within one or two days, the condition will resolve internally. Whenever slight pain and fever are felt from a minor carbuncle or furuncle, use raw licorice root nodes (Gancao Jie). Do not roast or bake; dry them in the sun. If sunlight is unavailable, dry them over a steamer lid using low heat, then grind into a fine powder. Mix 2-3 qian with hot wine and take orally. After several doses, both pain and fever will cease.
For treating carbuncles and deep abscesses that have not yet hardened, as well as cases involving qi and blood stagnation resulting in swollen lumps, lightly stir-fry Evodiae Fructus (Wuzhuyu), grind into a fine powder, and mix with egg white for topical application. This is miraculous! It is suitable for mild cases.
Divine Formula for Treating Carbuncles and Deep Abscesses on the Back:
Honeysuckle Flower (Jinyinhua, also known as Renhan Cao)
Harvest the leaves and grind them to extract the juice. Use any amount, place it in a porcelain bottle, add water, and decoct strongly using alternating medium and high heat. While hot, add good quality unadulterated wine, mixing the herbal juice and wine equally. Boil for more than ten times, filter out the dregs, and drink frequently. Dry the remaining dregs, grind and sieve them into a fine powder. Make pills the size of paulownia seeds using a paste made from wine-boiled flour. Take thirty pills each time, swallowed with warm wine on an empty stomach. These pills can be taken regularly once the illness has subsided slightly, due to their mild potency.
Preventive Formula for Carbuncles and Deep Abscesses: Taking this medicine ensures lifelong immunity from this disease.
Astragali Radix (Huangqi, seven liang). Select straight, soft stalks resembling arrow shafts; discard roots and branches. Half is used raw: finely chopped and dried. Half is cut into inch-long segments, flattened, moistened with honey water, stored in a clay vessel covered tightly, steamed three times over a rice steamer, then removed, dried, and crushed.
Glycyrrhizae Radix et Rhizoma preparata (Fencao, one and a half liang of purified material without nodes and peel). Half is used raw: finely chopped and dried. Half is roasted until yellow, then chopped and dried.
Grind the above two herbs into a fine powder. Take two qian each time, decocted in plain boiled water for morning and noon doses; normally taken as a decoction. At night, while drinking wine, mix the first cup with the powder. Regular consumption in this manner prevents carbuncles and deep abscesses for life.
Note: The above formulas do not appear in other treatises; they are collected here and appended after the main discussions.
Cervical carbuncle (Naoju) should not be treated with moxibustion, as it may draw qi upward, causing phlegm, saliva, pus, and blood to rush up, leading to death as quickly as flipping a hand. One should urgently moxa Zusanli (ST36) and Qihai (CV6), and gradually administer medicines that cool the chest and diaphragm and resolve blood stasis, allowing the patient some relief. This theory is recorded in *Tongshen Fanglun*. Cervical carbuncles and deep abscesses in the throat were traditionally considered incurable. This moxibustion method guides toxic pathogens downward, which is theoretically sound. Those suffering from this disease should not sit idle awaiting death; they should believe in and use this method.
Trichosanthis Powder: Treats breast carbuncles and "nai lao" (a term commonly used today for the early stage of this disease) in women, with miraculous effects.
Trichosanthis Fructus (Gualou, one fruit). Remove the peel, dry by baking, and grind into powder. For urgent use, crush thoroughly. Fruits with many seeds are more potent.
Angelicae Sinensis Radix (Danggui, half a liang). Wash clean, remove the radix tip, dry by baking, and slice thinly.
Glycyrrhizae Radix et Rhizoma (Gancao, half a liang). Finely chop and use raw.
Myrrha (Moyao, one fen). Grind separately.
Boswelliae Resina (Ruxiang, one qian). Grind separately.
Combine the above ingredients with three sheng of unadulterated wine in a silver or ceramic vessel. Simmer slowly over low heat until one sheng of clear liquid remains. Divide into three doses, taken long after meals. If "nai lao" symptoms occur, take this medicine immediately to eradicate the root cause. If the toxin has already formed pus, it will transform the pus into yellow fluid; if the toxin has not yet formed, it will be excreted through urination and defecation. In severe cases, repeat the dosage to reduce the illness. Although there are many formulas for female breast abscesses, this single formula is unparalleled in its miraculous efficacy, never failing.
Commentary: The above two formulas treat cervical carbuncle and breast carbuncle respectively, neither of which relates directly to back carbuncles. However, since these are from Li Xun's book, they are included here.
