痈疽之脓未熟，不可轻动刀针，破伤出血，反使肿痛，毒瓦斯走散加重。至患上四围
腐肉已成，须得烂透，方可用铜钩搭起剪刀，轻缓剪去。一觉痛处，切不可剪。再待腐熟
剪之，至见鲜红肉。若犯，动则痛作血流，尤难收口，慎之。
凡红肿 痛外症，最忌火针艾灸，并饮酒浆。不然，助火串毒，更痛肿异常，疔疮
尤忌，犯之便走黄延肿，不可治疗。
外科应用诸药，总宜现配现用，气力始足，易于去病。若是陈久，失其本性，鲜能
应效，岂不误人？独降药愈陈愈妙。
咳嗽有日，口干喉燥，舌下生细粒，胸膈微痛延迁，痰带白脓，腥臭味。
风寒与痰湿，走窜脉络，结为流注，愈者将愈，发者又发，延绵不已，多进阳和汤
可效。若皮色红者，不可用热药。（附方∶）

用火硝和明矾各一两，研磨成粉末，放入小铁锅中，用炭火加热使其熔化。待药液变成干硬状态并凝结在锅底后，再加入一两水银。在水银覆盖于硝矾形成的硬壳之上后，倒扣一个大碗在锅上，再用蘸有盐水的棉纸条将碗口四周塞紧，防止气体泄漏。接着用沙灰包裹住碗身的一半，用一个秤锤压住碗底，并在碗底放置少许棉花。先使用文火（小火），后改用武火（大火）煅烧三炷香的时间，观察碗底的棉花若变黑焦，说明药物已经炼制成功。此时熄火等待冷却，揭开碗刮下炼制的药物备用。

以上药材分别研磨成粉末，或者用糯米饭捣烂溶化后混合制成条状，备用，使用时不觉疼痛。
痈疽的脓液尚未成熟时，不可轻易动用刀针，以免破伤出血，反而导致肿痛加剧，毒气扩散使病情加重。等到患处周围腐肉已经完全腐烂透彻，才可用铜钩挑起剪刀，轻轻缓慢地剪去腐肉。如果感到疼痛，切不可剪割。需再等待腐肉熟透后再行剪除，直到露出鲜红的肌肉组织。如果违反此原则，一动则疼痛发作且血流不止，伤口更难愈合，务必谨慎。
凡是出现红肿疼痛的外症，最忌讳使用火针和艾灸，以及饮酒喝浆。否则，会助长火势、窜动毒邪，导致肿痛异常剧烈，疔疮尤其忌讳，一旦触犯就会导致“走黄”（毒邪内陷攻心）并蔓延肿胀，难以治疗。
外科应用的各种药物，总宜现配现用，这样药效才充足，易于祛除疾病。如果是存放已久的陈旧药物，失去了其本性，很少能奏效，这难道不是误人吗？唯独降药是越陈越好。
咳嗽多日，口干喉燥，舌下生出细粒，胸膈部位轻微疼痛且迁延不愈，痰液中带有白色脓液，气味腥臭。
风寒与痰湿之邪，流窜于脉络之中，凝结形成流注（一种多发于四肢肌肉深部的漫肿无头疾患）。痊愈的即将痊愈，复发的再次发作，绵延不断，多服用阳和汤可以见效。如果皮肤颜色发红，则不可使用热性药物。（附方：）

Use one tael of saltpeter (Natrii Nitras) and one tael of alum (Alumen), grind them into powder, and put them into a small iron pot. Melt them over charcoal fire. Wait until the mixture turns dry and hard, forming a crust at the bottom of the pot. Then add one tael of mercury (Hydrargyrum). Cover this with a large bowl placed upside down over the pot. Seal the four sides of the bowl tightly with cotton strips dipped in salt water to prevent gas leakage. Protect half of the bowl with sand and ash. Place a weight (such as a steelyard counterpoise) on the bottom of the bowl. Put a little cotton wool at the bottom of the bowl. First use mild heat (Wen Huo), then strong heat (Wu Huo) for the duration of three incense sticks. Observe if the cotton wool becomes blackened and scorched; this indicates that the medicine has been successfully sublimated. Extinguish the fire and wait for it to cool. Uncover the bowl and scrape off the sublimated drug for use.

Grind each ingredient into powder separately, or mash glutinous rice until dissolved and mixed with the powder to form strips, for use without causing pain.
When the pus of an abscess or carbuncle is not yet ripe, do not lightly use needles or knives. Breaking the skin and causing bleeding may instead worsen swelling and pain, causing toxic factors to scatter and aggravate the condition. Only when the necrotic flesh around the lesion has completely rotted through should you use a copper hook to lift scissors and gently and slowly cut away the dead tissue. If pain is felt, absolutely do not cut. Wait until the necrotic tissue is fully mature before cutting again, until fresh red meat is visible. If this rule is violated, movement will cause pain and bleeding, making wound healing particularly difficult. Be cautious.
For external symptoms characterized by redness, swelling, and pain, moxibustion and fire needles are strictly contraindicated, as is drinking alcohol or fermented beverages. Otherwise, these actions will assist fire and disperse toxins, leading to abnormal and severe swelling and pain. This is especially true for carbuncles (Ding Chuang); violating this prohibition can lead to "Zou Huang" (toxic invasion of the heart/mind) and spreading swelling, which becomes untreatable.
All medicines used in surgery should ideally be prepared and used immediately so that their potency is sufficient and they can effectively eliminate disease. Old medicines stored for a long time lose their natural properties and rarely produce effective results; would this not harm patients? However, Sublimated Mercury (Jiang Yao) is better the older it is.
Coughing for several days, dry mouth and throat, fine granules growing under the tongue, slight lingering pain in the chest and diaphragm, sputum containing white pus with a fishy odor.
Wind-cold combined with phlegm-dampness wandering through the collaterals and knotting together forms Liuzhu (a diffuse swelling without a head, often occurring deep in the muscles of the limbs). Cases that are healing will heal; cases that recur will flare up again, persisting endlessly. Taking Yanghe Decoction (Yanghe Tang) frequently can be effective. If the skin color is red, hot-natured medicines must not be used. (Attached Formula:)
