凡疮疡初起，病邪由内向外透发者，应当立即使用灸法。然而灸疮的方法有多种，因此在此说明。如果是病邪由外向内陷入者，则不宜使用灸法，适宜采用托里透脓之法；若是病邪由内向外透发者，适宜使用灸法。具体的灸法包括：隔蒜片灸、附子片灸，或者使用香豉饼、香附饼以及生姜片等进行灸治。这些方法能使毒气宣散而消除。《内经》说：“下陷的病症用灸法。”如果疼痛，就灸到不痛为止；如果不痛，就灸到有感觉（痛）为止。如果是瘙痒或麻木，也都适用灸法。如果疮疡面积大且脓头多，可以将大蒜捣成泥做成饼，铺上艾绒进行灸治，这是灵活变通的方法，疗效非常迅速，不可对此轻视疏忽。
凡是痈疽已经化脓的，必须紧急使用铍针排出脓液，血液中的毒素从此泻出而不再留存。好的肌肉就不会腐烂，使人精神恢复，气血再生，肌肉不至于败坏损毁。如果是治疗疔毒，先用针刺其四周及中心，排出恶毒之血，然后再施灸，立刻痊愈。内服追疔托里的药物，不出几天就能安定康复。
砭石、针、刀、镰是决断疮毒的器械。所谓疮毒适宜放血，意在尽快去除，不可延缓，恐怕毒势发生走窜变化。《内经》说：“病在血脉，用针石决破。”岐伯《五治论》说：砭针即是磁石，锋芒锐利快速，决泄毒邪十分方便，这是东方民众擅长使用的技法。对于疮疖丹瘤涂生油于赤肿之上，用砭石刺之出血，妙处在于合乎适宜，也不可以过度。
火针的使用最讲究得法，见效突然迅速。凡是痈疽位置深的，用火针时不可浅刺；痈疽位置浅的，针刺也不可深。关键在于适中，达到治愈疾病即可。所谓肌肉丰厚肿胀、脓液深重，担心疮口小容易闭合，导致脓水排出不畅，所以选用大针。火针形状如火筋，尖端圆钝，用纸包裹，在灯上烧红，观察疮头准确纳入。如果未穿透，再行纳入，务必确切，必须使脓水容易流出，毒邪容易消散。如果是疖毒、阳疮且浅小，则不使用此法。专门用于治疗附骨痈疽，毒邪不能外出的情况，所以用火针打开疮口，随即用蘸油的纸捻子引流，外用膏药贴敷。像这样的毒邪，若不使用火针，因畏惧火针而拖延日久，会导致毒邪内攻，腐蚀筋骨，毒邪从何化解？脓液从何排泄？妙处在于不可太早，也不可太迟，贵在医生的神妙运用。
Whenever a sore or ulcer first appears, if the pathogen is moving from the interior to the exterior, moxibustion should be applied immediately. However, there are various methods for treating sores with moxibustion, so they are explained here. If the pathogen is moving from the exterior to the interior (invading inward), moxibustion is not suitable; instead, methods to support the interior and promote pus discharge (Tuo Li) should be used. If the pathogen is moving from the interior to the exterior, moxibustion is suitable. Methods include moxibustion with slices of garlic, slices of Aconite (Fuzi), or cakes made from fermented soybeans (Xiangchi), Cyperus rotundus (Xiangfu), and slices of ginger. These methods allow the toxic factors to disperse and dissipate. The *Neijing* states: "For sinking conditions, use moxibustion." If there is pain, moxa until the pain ceases; if there is no pain, moxa until sensation (pain) returns. For itching or numbness, moxibustion is also applicable. If the sore is large with many heads, crush garlic into a paste to form a cake, place mugwort on it, and apply moxibustion. This is a flexible method with very rapid efficacy; one must not treat this lightly or negligently.
When an abscess or carbuncle has formed pus, it is necessary to urgently drain the pus using a Pi needle (a flat-bladed surgical knife). The blood toxins will thus be discharged and no longer remain. Healthy flesh will not rot, allowing the patient's spirit to recover and Qi and Blood to regenerate, preventing the muscles from degenerating or being damaged. When treating Ding toxicity (hard-rooted suppurative infection), first prick the four sides and the center with a needle to remove the evil, toxic blood, then apply moxibustion for immediate cure. Internally administer herbs that pursue Ding toxicity and support the interior; within a few days, the condition will stabilize.
Bian stones, needles, knives, and sickles are instruments for resolving sore toxins. The principle that sore toxins are suitable for bloodletting implies the urgency of removal; delay is inadvisable as it risks the toxin spreading. The *Neijing* states: "When the disease is in the blood vessels, resolve it with needles and stones." Qibo's *Wu Zhi Lun* states: Bian needles are made of magnetite, with sharp and swift edges, making them convenient for draining toxins. This technique was mastered by people in the East. For sores, boils, Dan tumors, or red swelling, apply raw oil on the affected area and pierce it with a Bian stone to bleed. The subtlety lies in appropriateness; one must not overdo it.
The use of fire needles requires proper technique for sudden and effective results. For deep abscesses or carbuncles, fire needle insertion must not be shallow; for superficial ones, it must not be deep. The key is to hit the middle ground, stopping when the disease is cured. In cases where flesh is thick, swollen, and abundant with deep pus, there is a fear that the small sore opening may close easily, hindering the free flow of pus. Therefore, a large needle is selected. The fire needle resembles a fire rod, with a round and blunt tip, wrapped in paper, and heated red-hot in a lamp. Observe the sore head accurately and insert it. If penetration is not achieved, insert again, ensuring precision, so that pus flows easily and toxins dissipate. This method is not used for superficial and small Yang sores or boils. It is specifically used for Fu Gu Yong Ju (bone-deep abscesses/carbuncles) where the toxin cannot exit outward. Thus, a fire needle is used to open the sore, followed by inserting an oiled paper wick for drainage, and covering with a plaster externally. For such toxins, if the fire needle is avoided due to fear and treatment is delayed, the toxin may attack inward,腐坏 (rotting) bones and muscles. How would the toxin be resolved? How would the pus be drained? The subtlety lies in timing: neither too early nor too late, relying on the physician's divine skill.
