【方歌】治疗痈疽、发背、痔疮瘘管及各类疮疡，牛膝蒸法最为适宜。将牛皮胶熬至浓稠后摊在纸上贴敷于患处，再用醋煮过的软布趁热覆盖在胶纸上进行热敷，效果良好。此法适用于温毒疮疡瘙痒且脓液排尽的情况，清洗时可使用胶纸配合贯众汤。
【注】对于痈疽、发背、痔漏、恶疮、廉疮（指生于颈侧或腋下的疮疡）以及久治不愈难以收敛的疮口，取一块牛皮胶，加水熬制到稀稠适度，涂抹在厚纸上，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，待稍凉后再更换，持续蒸疗直到疮口发痒、脓液完全排出为止。预先准备二两贯众，煎汤趁热清洗，去除胶纸后，外用膏药贴敷。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。
【方歌】若痈疽属于阴证，病程约半个月，疮口不起发、不溃破，质地坚硬如石，毒邪与脓液郁结，导致患者产生烦躁情绪，此时应优先采用拔法。用铍针在疮顶呈“品”字形刺开三个孔，若流出脓血颜色鲜红为顺证，若呈紫黑色则难治。
【注】痈疽阴证，在发病十五天左右，疮口不能起发，脓液位置深而不能向外溃破，疮势坚硬，沉重得像背着石头一样，毒邪和脓液向内侵蚀好肉，导致患者产生烦躁感。适宜先用药筒拔法，使毒邪和脓液有出路而排出。预先将竹筒放入药水中煮沸；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，根据疮口的高低情况，将竹筒乘热扣在疮孔上，拔出脓血。若脓血红黄鲜明，为顺证，容易治疗；若脓血紫黑，为败证，难以治疗。
方剂：煮竹筒方
组成：羌活、独活、紫苏、蕲艾、菖蒲、白芷、甘草（各五钱），连须葱（二两）。
用法：用水十碗，煮沸数次备用。其次取一段新鲜嫩竹，长七寸，直径一寸半，一头保留竹节，刮去青皮，厚度约一分，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。将装有药水的锅放在病人床前，取出竹筒倒掉药水，趁热迅速扣合在疮顶的针孔上，按紧自然吸附。片刻后药筒变温，拔掉杉木塞子，竹筒容易脱落，外用膏药盖贴，注意不要受风。如果脓血未排尽，第二天再煮竹筒，仍按原来的孔位再次拔除，这是治疗阴疮挤脓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】药水煮竹筒具有奇效，能让疮疡排脓而不受疼痛。配方包括菖蒲、紫苏、羌活、独活、艾叶、白芷、甘草，加上整根带须的葱和竹筒一起水煎，用于排脓。
[Prescription Verse] For treating carbuncles (Hong Ju), back carbuncles (Fa Bei), hemorrhoidal fistulas (Zhi Lou), and various sores, the Niu Xi steaming method is most appropriate. Boil ox-hide glue (Niu Jiao) until thick, spread it on paper, and apply to the affected area. Then, use soft cloth boiled in vinegar to cover the glue paper while hot for steaming therapy, which yields good results. This method is suitable for warm-toxic sores with itching and complete pus discharge; washing can be done using glue paper combined with Guanzhong Decoction.
[Annotation] For carbuncles, back carbuncles, hemorrhoidal fistulas, malignant sores, Lian sores (sores occurring on the side of the neck or armpit), and chronic sores that are difficult to heal and close, take a piece of ox-hide glue (Niu Jiao), boil it with water to the proper consistency, spread it on thick paper, and cut off pieces to apply to the sore opening. Next, boil two pieces of soft cloth in strong vinegar, place them over the glue paper while hot for steaming therapy, replace when slightly cool, and continue until the sore itches and all pus is discharged. Prepare two liang of Cyperus rotundus (Guan Zhong), decoct in water, wash with hot liquid, remove the glue paper, and apply external plaster externally. The next day, repeat the steaming and washing as before, until all pus is discharged and the sore dries up.
[Prescription Verse] If the carbuncle belongs to Yin syndrome (Yin Zheng), around half a month into the course, the sore does not rise or ulcerate, becoming hard and firm like stone, with toxic pus stagnating, causing restlessness. In such cases, extraction should be prioritized. Use a Pi needle (Bing Zhen) to make three punctures in a "pin" character pattern on the top of the sore. Fresh red pus indicates a favorable condition (Shun Zheng), whereas purple-black pus is difficult to treat.
[Annotation] For carbuncles of Yin syndrome, around fifteen days after onset, the sore fails to rise, pus is deep and cannot ulcerate outwardly, the lesion is hard and heavy like carrying a stone, and toxic pus internally erodes healthy tissue, causing restlessness. It is advisable to first use the medicinal bamboo tube extraction method (Yao Tong Ba Fa) to provide an outlet for toxic pus. Pre-boil a bamboo tube in medicinal liquid. Then, use a Pi needle (Bing Zhen) to make three punctures in a "pin" character pattern within one cun inside the top of the sore, at a depth of one cun or half a cun, depending on the height of the sore. Place the bamboo tube over the puncture while hot to extract pus and blood. Red and bright yellow pus indicates a favorable condition (Shun Zheng) and is easy to treat; purple-black pus indicates a deteriorating condition (Bai Zheng) and is difficult to treat.
Formula: Bamboo Tube Boiling Formula
Composition: Notopterygii Rhizoma et Radix (Qiang Huo), Angelicae Pubescentis Radix (Du Huo), Perillae Folium (Zi Su), Artemisia argyi (Qi Ai), Acori Tatarinowii Rhizoma (Chang Pu), Angelicae Dahuricae Radix (Bai Zhi), Glycyrrhizae Radix et Rhizoma (Gan Cao) (each 5 qian), Scallion with roots (Lian Xu Cong) (2 liang).
Usage: Use ten bowls of water, boil several times, and set aside. Take a section of fresh young bamboo, seven cun long, with a diameter of one and a half cun, keeping one end with the node. Scrape off the green skin, leaving a thickness of about one fen. Drill a small hole near the node and plug it with a fir wood strip. Place it in the previously prepared medicinal liquid and boil dozens of times. Place the pot containing the medicinal liquid near the patient's bed. Remove the bamboo tube, pour out the liquid, and immediately press it hot onto the needle puncture at the top of the sore, pressing firmly so it adheres naturally. After a short while, when the bamboo tube warms up, remove the fir wood plug; the tube will detach easily. Cover with external plaster and avoid wind exposure. If pus and blood are not fully discharged, boil the tube again the next day and extract from the same holes. This is an excellent method for extracting pus from Yin sores without causing pain; do not neglect it. For Yang sores (Yang Chuang), this method is unnecessary as it may damage Qi and Blood; exercise caution.
[Prescription Verse] Medicinal liquid-boiled bamboo tubes have miraculous effects, allowing sore pus to discharge without pain. The formula includes Chang Pu, Zi Su, Qiang Huo, Du Huo, Ai Ye, Bai Zhi, Gan Cao, whole scallions with roots, and bamboo tubes, decocted in water to discharge pus.
