凡是痈疽毒气盛大，肿胀漫无边际，根基散乱无聚，这种毒邪不集中的情况，是最为凶险的征象。难以消散，也难以透发，拖延日久，必然产生许多变化。因此，收敛疮根这一方法，是绝对不可缺少的。又有疮疡生在骨节转动之处，化脓腐肉，恐怕阻碍关节活动，也应当外敷“移毒末子”，使毒邪移至一侧，让开要害部位，这样即使化脓，也可避免损伤运动功能。古代这类方药，虽然不少，但见效的寥寥无几。这是朱氏（朱仁康等外科名家）常用的药物，比古书中的成方见效迅速，是收敛疮根必不可少的药品。外科书中另有同名药物，是用芙蓉叶、苍耳草两味药捣烂涂抹，只用来治疗热疖轻证，不能与此方相比。
大五倍子（去除蛀屑，微炒至结团，冷却后研细，三两） 杜蟾酥（干燥后研细，五钱） 藤黄（三两，先用优质的白芨、山慈菇各三两，制南星一两）
以上五味药先放入陈年好醋两大碗中，用文火熬煮浓缩，过滤去掉药渣，然后将经过醋煮的藤黄一同再熬成膏状，等到极度浓稠时，再加入五倍子、蟾酥、二矾（明矾与绿矾）的细末。搅拌均匀后离火，再放入麝香细末三钱，捣匀制成锭剂，在阴凉处干燥后收藏。使用时用醋磨浓，涂在疮根四周，干了就用醋润湿，一天洗去一次再重新涂抹，效果极佳。想要移毒使其偏向一侧，就按上述方法只涂在一侧，涂药的地方自然会消肿，而毒邪就会聚集在未涂药的另一侧。这样可以保证骨节不致受损，这就是避重就轻的方法。
这就是升丹，一切溃疡都可以通用，拔毒提脓最为灵验。凡是寻常的病症，得到这个已经足够了。但是湿疮有水无脓以及顽固恶证、腐肉不脱，或者形成缸口状溃疡，或者黑腐粘韧，久溃不愈的败疡，则有另外适用的药末，不是此药能治愈的。凡是溃疡靠近口、眼处的不使用，乳头、肚脐、阴部、下疳也不使用。
先将硝石、枯矾研细放入锅底铺平（用小铁锅），中间做成凹形，放入水银，选一个平底圆浑的瓷海碗覆盖在上面，听碗中发出轻微的声响，知道硝石和枯矾自行溶解，看到碗口没有黄紫色的气体飞出，这才算没有漏气跑汞（一旦看见碗口出烟，说明汞已经外泄）。最好隔一宿再看，打开看时，碗中满是粘着的鲜红色药粉，而锅底只有白色的药底，这是最好的火候状态。碗中的药，表面一层，轻浮如粉，先用鸡毛扫下来另外储存。这层药性薄，只能用于轻证。扫尽浮药后，碗壁上还有一层粘住的药。用刀刮取这层粘住的药，浓稠的成片状。这层药力量较强，可以治疗大毒重证。放入油钵中细细研磨，极细才能使用。药色以鲜红如朱砂，明亮艳丽如晚霞者为最佳，说明火候适中。如果火候不够，颜色发黄，且有淡黄色，就是市肆中所谓的“黄升药”，力量最弱不可用，而且火候未到，汞性未完全转化，多见气孔，星星点点可辨，仍然是水银。将其掺入溃烂之处，危害极大。如果火候太过，则颜色焦紫或像酱色，也不可再用。间或有满碗呈现晕圈状，一圈鲜红，一圈深黄，一圈青紫，圈圈颜色不同的，则是炉火作用的结果，古人所说的药炉中自有神妙莫测的道理，确实是不多见的，实际功效也是一样的。如果偶然遇到，可以将各色扫开，分别储存，以供博物研究。总之，颜色以鲜红明艳为第一，也有晦暗滞涩的，那是坏药。如果上火时有烟雾腾出，说明汞已经跑掉，碗中可能一点不剩，不可不慎。炭要预先挑选敲击有声如铜声的，才可以合用，劣质炭不可用。火候不佳药力不及，功用必然达不到要求。市肆中有炼成的成品，尝试使用，病人皆嫌疼痛，而自制的则不痛，这一定有原因。俗话说是因为陈旧的不痛，新炼的痛，其实并不完全如此。我曾试用新炼的丹，也未见疼痛。但必须研磨得极细，使用此药只用新棉花蘸取药末，轻轻弹上薄薄一层，只见薄薄的深黄色就足够了，如果用多了则会非常疼痛。门外的人看见了，必定会说吝啬药末不肯重用，却不知道此丹力量很浓，绝对不能多用。炼丹时炉中剩下的白色炉底，也可以研细，加入到治疗疥疮奇痒的药中。但是枯矾收湿止痒，重用作会疼痛，应该稍微少用一些。
Whenever there is a carbuncle or ulcer with severe toxicity, presenting as diffuse swelling without clear boundaries and a scattered root, the pathogenic factor fails to consolidate. This is the most ominous prognosis. It is difficult to resolve or erupt; if delayed for a long time, it will inevitably lead to numerous complications. Therefore, the method of consolidating the root of the sore is absolutely indispensable. Furthermore, when sores occur in areas between joints where movement takes place, leading to pus formation and tissue necrosis that may hinder joint function, one should apply external powders for "transferring toxicity" (Yi Du). This moves the toxicity to one side, clearing the vital area, so that even if pus forms, damage to motor function can be avoided. Although ancient formulas of this type are not rare, few have proven effective. The formula used by the Zhu school is more rapid in effect than the fixed prescriptions in ancient texts and is an essential item for consolidating the sore's root. There is another preparation with the same name in surgical texts, made by crushing and applying Hibiscus tiliaceus leaf (Furong Ye) and Xanthium strumarium herb (Cang Er Cao), which is only used for treating mild cases of hot boils and cannot compare with this formula.
Daxiaobeizi (Galla Chinensis, three taels: remove worm-eaten fragments, lightly stir-fry until clumped, cool, and grind into fine powder) Duchansu (Toad Venom, five qian: dry and grind into fine powder) Tenghuang (Parthenium hysterophorus Rhizome, three taels: first prepare with Baiji, Shancigu, and Zhinanning as follows)
Baiji (Bletilla striata Rhizome, three taels) Shancigu (Fritillaria cirrhosa Bulb, three taels) Zhinanning (Arisaema cum Bile, one tael)
First, take the latter five herbs and boil them in two large bowls of aged rice vinegar over gentle heat until concentrated. Strain out the dregs. Then add the Tenghuang previously boiled in vinegar and continue simmering until it becomes a thick paste. When extremely concentrated, mix in the fine powders of Daxiaobeizi, Duchansu, and Erfan (Alumen and Melanterite). Stir evenly, remove from fire, and add Sanqie (Moschus, three qian ground into fine powder). Pounded into uniformity, form into pills/cakes, and store after drying in the shade. When using, grind with vinegar to a thick consistency and apply around the four sides of the sore's root. If it dries, moisten with vinegar. Wash off once a day before reapplying; this is extremely effective. To transfer the toxicity to one side, apply according to the above method only on one side. The applied area will naturally reduce swelling, while the toxicity gathers on the untreated side. This ensures the joint is not damaged, representing the method of avoiding severity and choosing lightness (Bi Zhong Jiu Qing).
This is Shengdan (Calomelas/Red Sublimate), which can be used generally for all ulcers and is most effective for extracting toxicity and promoting pus discharge. For ordinary conditions, this is sufficient. However, for wet sores with water but no pus, stubborn malignant conditions with non-detaching necrotic tissue, crater-like ulcers, black tough necrosis, or chronic discharging ulcers, other specific medicated powders are required, as this formula alone cannot cure them. Do not use near the mouth or eyes. Do not use on nipples, umbilicus, genitalia, or chancres.
Shuiyin (Mercurius, one tael) Huoxiao (Natrii Nitras, one tael) Kufan (Alumen, one tael)
First, grind Huoxiao and Kufan finely and spread them flat at the bottom of a small iron pot. Create a concave depression in the center, place Shuiyin inside, and cover with a round-bottomed porcelain bowl. Listen for slight sounds within the bowl, indicating that Huoxiao and Kufan are dissolving. Ensure no yellow-purple gas escapes from the rim of the bowl, confirming the furnace is sealed (if smoke appears at the rim, mercury has leaked). Ideally, wait overnight before opening. Upon inspection, the bowl should contain a sticky bright red substance, while the pot bottom retains only white residue, which indicates optimal firing. The top layer in the bowl is light and powdery; sweep it down with a chicken feather and store separately. This layer has weak potency and is suitable only for mild cases. After removing the floating powder, scrape the layer adhering to the bowl walls. This thicker,成片 (piece-form) substance has stronger potency and can treat severe toxic conditions. Grind it finely in an oil mortar until extremely fine before use. The ideal color is bright red like cinnabar or vivid like sunset clouds, indicating perfect firing. If under-fired, the color is yellow or pale yellow (known in markets as Huangsheng); its potency is weakest and it must not be used. Moreover, incomplete firing means mercury properties are not transformed; visible air bubbles indicate residual metallic mercury. Applying this to ulcerated areas causes great harm. If over-fired, the color becomes scorched purple or sauce-like, which is also unusable. Occasionally, the bowl shows concentric rings of different colors (bright red, deep yellow, cyan-purple), reflecting the mysterious effects of the furnace fire described by ancients. These are rare but equally effective. If encountered, separate and store each color for study. Generally, bright red and vivid colors are best; dull or stagnant colors indicate spoiled medicine. If smoke rises during heating, mercury has escaped, potentially leaving nothing in the bowl; caution is essential. Select charcoal that rings like copper when struck; inferior charcoal is unusable. Poor firing results in insufficient potency. Commercially prepared products often cause pain upon application, whereas homemade ones do not, suggesting a reason. Folk belief claims aged preparations are painless while new ones hurt, but this is not entirely true. I have tested newly prepared Dan without causing pain, provided it is ground extremely fine. Use fresh cotton to gently dab a thin layer of the powder onto the wound; a thin dark yellow coating is sufficient. Overuse causes severe pain. Laypeople may accuse you of being stingy with the powder, unaware that its potency is strong and excessive amounts are contraindicated. The white residue remaining in the furnace after firing can also be ground fine and added to remedies for pruritic scabies. However, since Kufan (Alumen) absorbs dampness and relieves itching, heavy use causes pain; therefore, use it sparingly.
