痈疽、发背、痔漏、恶疮，使用牛胶蒸法最为适宜。将牛皮胶熬至浓稠后摊在纸上贴在患处，用醋煮软的布趁热覆盖在胶纸上进行蒸疗效果良好。这种方法适用于温性易痒的疮疡，能使脓液排尽；之后可用贯众汤清洗，洗去胶纸，再外用膏药贴敷。
【注】对于痈疽、发背、痔漏、恶疮、久治不愈难以收敛的疮疡，取一块牛皮胶，加水熬制到稀稠适度，摊在厚纸上，每次剪下一块贴在疮口上。接着用浓醋煮两块软布，趁热覆盖在胶纸上进行蒸疗，稍凉后再更换，一直蒸到疮口发痒、脓液完全排出为止。预先准备二两贯众，煎汤趁热清洗，去掉胶纸，外部再用膏药贴敷。第二天按照之前的方法继续蒸洗，直到脓液排尽、疮口干燥为止。
痈疽阴证在发病半月之内，疮疡不起发、不溃破，质地坚硬如石，毒邪郁结导致脓液内陷，引起患者烦躁不安，此时应优先采用拔法治疗。用铍针在疮顶呈“品”字形刺开三个孔，若流出的脓液颜色鲜红为顺证，若呈紫黑色则难治。
【注】痈疽阴证，在十五天左右，疮疡不起发，脓液深藏不能向外溃破，疮势坚硬沉重如背负石头，毒邪和脓液向内侵蚀好肉，导致患者产生烦躁情绪。应当先用药筒拔法，使毒邪和脓液有出路排出。预先将竹筒和药水一起煮沸；然后用铍针在疮顶一寸范围内，呈“品”字形刺开三个孔，深度为一寸或半寸，根据疮疡的高低情况，取竹筒趁热扣在疮孔上，拔出脓血。若脓血红黄鲜明，属于顺证，容易治疗；若脓血紫黑，属于败证，难以治疗。
煮竹筒方：羌活、独活、紫苏、蕲艾、菖蒲、白芷、甘草（各五钱），连须葱（二两）。用水十碗，煮沸数次备用。其次选用鲜嫩竹子一段，长七寸，直径一寸半，一头保留竹节，刮去青皮，厚度约分许，靠近竹节处钻一个小孔，用杉木条塞住，放入前面的药水中，煮沸数十次。将煮药的锅放在病人床前，取出竹筒倒掉药水，趁热迅速扣在疮顶针孔上，按紧自然吸附。待片刻药筒变温，拔掉杉木塞子，竹筒容易脱落，外部用膏药盖贴，不要让患处受风。如果脓血未排尽，第二天再煮竹筒，仍按原来的孔再次拔除，这是治疗阴疮挤出脓液而不受疼痛的好方法，不可忽视。如果是阳疮，则不必使用此法，恐怕损伤气血，务必谨慎。
【方歌】药水煮竹筒有奇效，能让疮疡脓液排出而不受疼痛，方中包含菖蒲、紫苏、羌活、独活、艾草、白芷、甘草，加上整根葱和竹筒用水煮浓。
Carbuncles, back carbuncles, hemorrhoids with fistulas, and malignant sores are best treated with the method of steaming using ox-hide glue. The glue is boiled until thick, spread on paper, and applied to the affected area; soft cloth boiled in vinegar is then applied hot for steaming, which is effective. This method is suitable for warm-type sores that itch easily, allowing pus to drain completely. Afterwards, wash with Guanzhong Decoction (Jianzhong Tang), remove the glue paper, and apply external plasters.
[Note] For carbuncles, back carbuncles, hemorrhoids with fistulas, malignant sores, and chronic ulcers that are stubborn and difficult to heal, take a piece of ox-hide glue, boil it with water to the appropriate consistency, spread it thickly on paper, and cut off pieces to apply to the sore opening. Then, boil two pieces of soft cloth in strong vinegar, place them hot over the glue paper on the skin for steaming. Replace when slightly cool, continuing until the sore itches and pus drains completely. Prepare two liang of Cyperus rotundus (Guanzhong), decoct in water, and wash hot to remove the glue paper, then apply external plasters. Continue steaming and washing the next day until pus is exhausted and the ulcer dries up.
In the yin syndrome of carbuncles within half a month after onset, the sore does not rise or suppurate, remaining hard and firm like a stone. With toxic pus stagnating internally causing restlessness, extraction should be prioritized. Use a Pi needle to make three holes in a "pin" character pattern on the top of the sore. Fresh pus indicates a favorable condition, while purple-black pus indicates difficulty in treatment.
[Note] In the yin syndrome of carbuncles, around fifteen days after onset, the sore fails to rise or suppurate externally, with deep-seated pus unable to break out. The lesion is hard and heavy as if carrying a stone, with toxic pus eroding healthy tissue internally, causing restlessness. It is advisable to use the bamboo tube extraction method first to provide an outlet for toxic pus. Pre-boil bamboo tubes in medicinal liquid. Then, use a Pi needle to puncture three holes in a "pin" character pattern within one cun on the top of the sore, at a depth of one cun or half a cun, depending on the height of the sore. Take a bamboo tube and press it hot onto the sore holes to extract pus and blood. If the pus and blood are bright red and yellow, it is a favorable syndrome and easy to treat; if purple-black, it is a deteriorating syndrome and difficult to treat.
Formula for Boiling Bamboo Tubes: Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Zisu (Perillae Folium), Qi'ai (Artemisiae Argyi Folium), Changpu (Acori Tatarinowii Rhizoma), Baizhi (Angelicae Dahuricae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (each 5 qian); Lianxu Cong (Allii Fistulosi Bulbus with roots) (2 liang). Use ten bowls of water, boil several times, and set aside. Select a fresh tender bamboo segment, seven cun long, with an outer diameter of one and a half cun. Leave one end with the node intact, scrape off the green skin, thickness about one fen. Drill a small hole near the node and plug it with a fir wood strip. Place it in the aforementioned medicinal liquid and boil dozens of times. Place the pot containing the medicinal liquid near the patient's bed. Remove the tube, pour out the liquid, and immediately press it hot onto the needle holes on the sore top, pressing firmly so it adheres naturally. After a short while, when the bamboo tube warms up, remove the fir wood plug; the tube will fall off easily. Cover with an external plaster to prevent wind exposure. If pus and blood are not fully drained, boil the bamboo tube again the next day and extract through the same holes. This is an excellent method for draining pus from yin sores without pain; do not neglect it. For yang sores, this method is unnecessary as it may damage qi and blood; exercise caution.
[Formula Song]: Medicinal liquid-boiled bamboo tubes have miraculous effects, allowing pus to drain without pain. Contains Changpu, Zisu, Qianghuo, Duhuo, Aiye, Baizhi, and Gancao, boiled with whole scallions and bamboo tubes.
