论曰∶凡发背皆因服食五石寒食更生散所致，亦有单服钟乳而发者，有上世服之者，其
候率多于背两胛间。初起如粟米大，或痛或痒，仍作赤色。人初不以为事，日渐长大，不过
十日遂至于死。其临困之时，已阔三寸，高一寸，疮有数十孔，以手按之，诸孔中皆脓出。
寻时失音，所以养生者，小觉背上痒痛有异，即火急取净土水和如泥，捻作饼子，浓二分，
阔一寸半，以粗艾大作炷，灸泥饼子贴着疮上灸之，一炷一易饼子。若粟米大时，可灸七饼
即瘥。如榆荚大，灸七七饼炷即瘥。如钱大，可日夜灸之，不限炷数，仍服五香连翘汤。（方
见本卷痈疽门中。）及铁浆诸药攻之乃愈。又法，诸发背未作大脓，可以冷水射之，浸石令
冷熨之，日夜不住，瘥止。此病忌面酒五辛等。亦有当两肩上发者。
凡服石人，皆须劳役四体无令自安，如不尔者，多有发动。亦不得随便恣意取暖，称已
适情，必须遗欲以取寒冻。虽当时不宁，于后在身多有所益，无发动之虑耳。
凡肿起背胛间，头白如黍粟，四边相连，肿赤黑，令人闷乱，即名发背也。禁房室、肉
酒、面蒜。若不灸治，即入内杀人。若灸当疮上七八百壮。有人不识，多作杂肿治者皆死。
治发背及痈肿已溃未溃方∶
用香豉三升少与水和，熟捣成如薄泥，根据肿作饼子，浓三分以上，有孔勿覆孔中，布豉
饼以艾列其上灸之使温，温而热勿令破肉，如热痛即急易之，患当减，快得安稳，一日二度
灸之。如先有疮孔，孔中得汁出瘥。
治痈疽发背已溃、未溃及诸肿毒方∶
栝蒌根 榆白皮 胡燕窠 鼠坌土（各等分）
上四味为末，以女人月经衣水洗，取汁和如泥封肿上，干即易。溃者，四面封之，已觉
即封，从一日至五日令瘥。
治发背，背上初欲结痈方∶
大黄 升麻 黄芩 甘草（各三两） 栀子（三七枚）
上五味 咀，以水九升，煮取三升，分二服，取快利便止，不利更进。
治疗毒肿位置不固定，或者呈现赤色并伴有恶寒，或者心腹部刺痛、烦闷的方剂：这是由毒气深重所致。
麻子、赤小豆（各五升）、生商陆（三升）、附子（二两）、射干（三两）、升麻（四两）。
以上六味药，切碎，用水四斗，先煮前四味药，取汁二斗半，滤去药渣，接着将麻子研碎，与药汁混合煮沸一次，滤去药渣，再用此汁煮赤小豆至烂熟。每次服用五合，白天两次，夜间一次。以小便通利为度，肿胀消退即痊愈，同时食用豆子。
治疗一切肿毒，疼痛难以忍受的方剂：
取成熟的蓖麻子捣烂，敷在患处即可痊愈。
治疗各种疮疡附着白色痂皮后复发的方剂：
大蒜、鼠屎、香墨（等量）。
以上三味药研成粉末，每日敷用三次。
又一方：生花椒末、釜下土（等量）。
以上两味药研成粉末，用醋调和后涂抹患处。（《千金翼方》中有曲末，作为三味药使用）。
又一方：狗头骨、芸薹子（等量）。
以上两味药研成粉末，用醋调和后敷于患处。
又一方：用麻雀粪便加水调和后敷于患处。
又一方：烧葛蔓成灰封敷患处，可自行消散。用牛粪灰封敷也很好。
（论述一首，方剂十五首）
论述说：凡是发背，都是由于服用五石散、寒食更生散等药物引起的，也有单服钟乳石而发病的，有的甚至是祖先辈服用后遗留下来的病症，其症状大多出现在背部两侧肩胛之间。初起时像粟米大小，或者疼痛或者瘙痒，颜色发红。人们起初不以为意，日渐长大，不超过十天就会导致死亡。病危之时，疮口已宽三寸，高一寸，疮上有数十个孔洞，用手按压，各个孔洞中都有脓液流出。随即失音。所以养生的人，只要觉得背上痒痛有异常，就立即取洁净的泥土和水调成泥状，捏成饼子，厚度二分，宽度一寸半，用粗大的艾炷，灸在贴着疮口的泥饼上，每灸完一炷香就更换一个泥饼。如果在粟米大小时，可灸七个饼即痊愈。如果像榆荚那么大，灸四十九个饼和艾炷即痊愈。如果像铜钱那么大，可以日夜不停地灸，不限艾炷数量，同时服用五香连翘汤。（方剂见本卷痈疽门中。）再用铁浆等药物攻治才能痊愈。又一种方法，对于所有发背尚未形成大脓的情况，可以用冷水喷洒患处，浸湿石头使其变冷后熨敷患处，日夜不停，直到痊愈为止。此病忌食面食、酒类及五辛等食物。也有发生在两肩上方的。
凡是服用石药的人，都必须使四肢劳作，不要让自己安逸，如果不这样，多有发作。也不能随意贪图取暖，自称舒适，必须通过节制欲望来感受寒冷冻冽。虽然当时身体不安宁，但后来对身体多有益处，没有发作的忧虑罢了。
凡是肿胀出现在背部肩胛之间，头部白色如黍粟，四周相连，肿胀呈赤黑色，使人闷乱，这就名叫发背。禁止房事、肉食、酒、面食、大蒜。如果不进行灸治，毒邪入内会致人死亡。如果施灸，应在疮口上灸七八百壮。有人不认识此病，多当作一般杂肿治疗，结果都死了。
治疗发背及痈肿，无论已溃破或未溃破的方剂：
用香豉三升，加少量水，煮熟捣烂成薄泥状，根据肿胀形状做成饼子，厚度三分以上，如果有孔洞不要覆盖孔中，将豉饼铺在疮上，上面排列艾炷进行灸治使其温热，温热而不烫破皮肤，如果感到热痛就立即更换，患部就会减轻，很快得到安稳，每天灸两次。如果先前已有疮孔，孔中有汁液流出则痊愈。
治疗痈疽发背已溃破、未溃破以及各类肿毒的方剂：
栝蒌根、榆白皮、胡燕窠（燕子窝泥）、鼠坌土（老鼠洞里的土，各等量）。
以上四味药研成粉末，用妇女月经衣水洗取汁液，调和成泥状封敷在肿胀处，干了就更换。已溃破的，从四面封敷，刚感觉到症状就封敷，从一天到五天可使痊愈。
治疗发背，背上初起将要结痈的方剂：
大黄、升麻、黄芩、甘草（各三两）、栀子（三七枚）。
以上五味药，切碎，用水九升，煮取三升，分两次服用，以大便通畅为度，若不通畅再进服。
Treats toxic swelling with uncertain location, or presenting with redness and aversion to cold, or stabbing pain and restlessness in the heart and abdomen; this is caused by deep-seated and severe toxic qi. Formula:

(Discussion: One section; Formulas: Fifteen sections)
Discussion: All cases of "Fa Bei" (Back Carbuncle/Erysipelas of the back) are caused by taking Five-Mineral Powders (Wu Shi San), Han Shi Geng Sheng San, or similar mineral drugs. Some cases arise from taking only Stalactite (Gypsum Fibrosum/Hydrocerussite confusion in ancient texts, here likely referring to mineral deposits like Zhuru/Stalactite). Inherited usage from ancestors may also be a factor. The symptoms usually appear between the two scapulae on the back. Initially, it resembles a millet grain in size, accompanied by pain or itching, and reddish color. People often ignore it initially, but it grows day by day, leading to death within ten days. At the critical stage, the lesion is three cun wide and one cun high, with dozens of pores. Pressing with hands causes pus to exude from all pores. Voice loss occurs immediately. Therefore, those practicing health preservation should, upon feeling any unusual itching or pain on the back, urgently take clean earth, mix with water to form mud, shape into cakes (thickness: 2 fen, width: 1.5 cun). Apply coarse moxa cones on the mud cake placed over the sore. Replace the mud cake after each cone burns out. If treated when the size is like a millet grain, seven applications may cure it. If the size is like an elm seed, forty-nine applications may cure it. If the size is like a coin, moxibustion can be performed day and night without limit on the number of cones, while simultaneously administering Wuxiang Lianqiao Tang (Five-Spice Forsythia Decoction) (see this volume, Abscess and Ulcer section). Treat further with Iron Slag Water (Tie Jiang) and other medications for recovery. Another method: For Fa Bei before large abscess formation, spray cold water on the area, soak stones until cold, and apply as a cold compress continuously day and night until recovery. This disease contraindicates wheat products, alcohol, and the Five Pungent Spices (Wu Xin). It may also occur on both shoulders.
Anyone taking mineral drugs must engage in physical labor to avoid comfort/stasis. Failure to do so often triggers attacks. One must not seek warmth arbitrarily or indulge in comfort; instead, one must restrain desires and endure cold. Although uncomfortable initially, it benefits the body later and prevents future attacks.
When swelling arises between the back and scapulae, with a white head like millet, surrounded by connected red-black swelling, causing mental agitation, it is named Fa Bei. Contraindications include sexual activity, meat, alcohol, wheat products, and garlic. Without moxibustion treatment, the toxin enters internally and causes death. Moxibustion should consist of 700-800 moxa cones directly on the sore. Ignorance leads to misdiagnosis as general swelling, resulting in death.
Treats Fa Bei and carbuncles/swellings, whether ulcerated or non-ulcerated. Formula:
Fermented Soybean Paste (Douchi) 3 sheng, add a little water, cook thoroughly, and mash into a thin paste. Shape according to the swelling into cakes (thickness > 3 fen). Do not cover existing pores. Place the Douchi cake on the sore, arrange moxa cones on top, and moxibustate until warm. Ensure heat does not burn the skin. If painful due to heat, replace immediately. Symptoms will subside, providing relief. Perform moxibustion twice daily. If pores previously existed and discharge fluid, recovery occurs.
Treats carbuncles, Fa Bei (ulcerated/non-ulcerated), and all swollen toxins. Formula:
Trichosanthes Root (Trichosanthis Radix), Elm Inner Bark (Ulmus Alba Cortex), Swallow Nest Mud (Hirundo Nidus), Mouse Hole Soil (Mus Tunnellus Terra). Equal parts.
Grind the above four ingredients into powder. Wash women's menstrual cloth to extract juice, mix with powder to form a mud-like paste. Apply to the swelling. Change when dry. For ulcerated cases, apply around the four sides. Apply as soon as symptoms are felt. Recovery within one to five days.
Treats Fa Bei, specifically when a carbuncle is just beginning to form on the back. Formula:
Rhubarb Root (Rhei Radix et Rhizoma), Cimicifuga Rhizome (Cimicifugae Rhizoma), Scutellaria Root (Scutellariae Radix), Licorice Root (Glycyrrhizae Radix et Rhizoma); each 3 liang. Gardenia Fruit (Gardeniae Fructus) 37 pieces.
Coarsely crush the above five herbs. Decoct in 9 sheng of water, reduce to 3 sheng. Divide into two doses. Stop when bowel movement is smooth; if not smooth, administer again.
