所谓“追蚀”，是一种辅助治疗的方法，而非针刺疗法。当疮疡肿胀疼痛难以忍受时，可以在内服托里药中加入穿山甲、皂角刺、破故纸等具有腐蚀作用的药物；在外用方面，将针头散贴在疮顶，即可起到腐蚀作用，使疮口内的腐肉自然脱落，脓液排出，毒邪消散。也有用水蛭吮吸疮顶毒血的方法，这虽然是良法，但现代人大多厌恶它。现记录此法以备不时之需。
因为死肉坚硬且不腐烂，反而会侵蚀好肉，导致患处不在原处而扩大，致使患者日夜痛苦不安。若想使用腐蚀死肉的药，好肉会感到剧烈疼痛；若想使用生肌的药，反而会使溃烂加重。例如背痈、疔疮、杖伤中毒等，若内有死肉侵扰，若不急于用刀割除，恐怕内毒会侵入脂膜和脏腑，多会导致无法救治，难道不令人畏惧吗？《内经》说：“病在血脉，决之则愈。”又说：“厌恶针刀的人，不足以与其谈论医术的至高境界。”也可以先给其服用畏惊散一剂，效果更佳。
大凡疮毒已经平复，但脓水仍未减少，创面溃烂已稳定，仅有少许疼痛或瘙痒，肌肉尚未生长。如果不贴上膏药，赤红的肉芽缺乏遮盖保护，风冷之气难以抵挡。因此使用太乙膏等贴敷，可以偎护脓液、促进肌肉生长，风邪不能侵袭。内服应当补益托里，使气血调和通畅，精神恢复如初。至此身体强壮，各种疮疡又怎能导致败坏呢？
如果疮疡已经败坏，漏下不止，人体已经衰弱，多种治疗均无效，多年受苦，未遇良医，浪费钱财，心中已如死灰。再加上房事劳累，使疮肉变为紫黑色，败肉浮起，再遇到湿热磕碰导致恶血积聚，即使有冰片、乳香、没药、血竭等药物，怎么能治愈呢？殊不知另有良法，并非历朝疮疡书籍中所记载。我在江湖游历多年，遍访名山异人，多有相遇，求授良法，现记载于后，救活了许多人。能使阴气消散，肌肉红活，生肌长肉，脓水立即停止，妙不可言，言语难以尽述。
"Zhuisi" (Corrosive Therapy) is a method of auxiliary treatment, not involving acupuncture. When a carbuncle or ulcer is swollen and the pain is unbearable, one may add corrosive herbs such as *Chuan Shan Jia* (Pangolin Scales), *Zao Jiao Ci* (Gleditsiae Spina), and *Po Gu Zhi* (Psoraleae Fructus) to internal "Tuoli" (Supporting the Interior) decoctions. Externally, applying "Zhentou San" (Needle Head Powder) to the apex of the ulcer induces corrosion, causing foul necrotic tissue to slough off naturally, pus to drain, and toxins to dissipate. Another method involves using leeches to suck toxic blood from the apex of the ulcer. Although this is a good method, most modern people find it repulsive. It is recorded here for convenience of use.
This is because dead flesh is hard and does not rot, but instead erodes healthy flesh, causing the lesion to spread beyond its original site, resulting in severe pain and restlessness day and night. If one applies medication to remove dead flesh, the healthy flesh suffers intense pain; if one applies medication to regenerate muscle, the ulceration worsens. For example, in cases of back carbuncles, ding sores, or trauma-induced toxicity, if dead flesh invades internally, failure to urgently excise it with a knife may allow internal toxins to invade the subcutaneous fat membranes and viscera, often leading to untreatable conditions. Is there not reason to fear this? The *Neijing* states: "When the disease is in the blood vessels, lancing it leads to cure." It also states: "Those who are averse to needles and knives cannot be taught the highest subtleties of medicine." Alternatively, administering one dose of "Weijing San" (Fear-Needle Powder) beforehand yields better results.
Generally, when the toxin of an ulcer has subsided but pus and fluid remain abundant, the ulcerated area is stable, with only slight pain or itching, and muscle has not yet regenerated. If ointments are not applied, the red granulation tissue lacks protection, making it difficult to withstand wind and cold. Therefore, applying ointments such as "Taiyi Gao" (Great One Ointment) helps retain pus and promote muscle growth, preventing invasion by wind pathogens. Internally, one should tonify and support the interior to harmonize qi and blood and restore vitality. Once the body is strong, how can various ulcers lead to deterioration?
If the ulcer has deteriorated, with continuous leakage, and the patient is weak, unresponsive to various treatments, suffering for years without meeting a skilled physician, wasting money, and feeling hopeless, compounded by sexual exhaustion causing the ulcer tissue to turn purple-black, with floating necrotic tissue and accumulation of evil blood due to heat-dampness or physical trauma, even medications like *Bing Pian* (Borneol), *Ru Xiang* (Frankincense), *Mo Yao* (Myrrh), and *Xue Jie* (Dragon's Blood) would be ineffective. Little do they know there is another excellent method, not found in historical ulcer texts. Having traveled in the jianghu for years, I visited famous mountains and sought out extraordinary individuals, met many, and requested their secret methods. These are recorded below, having saved many lives. This method can dissipate yin qi, make muscles red and vibrant, regenerate tissue, and immediately stop pus discharge. It is wonderful; words cannot fully describe it.
