疔疮的危害，源于血中毒邪炽盛。这是由于气机凝滞、热邪阻滞而形成的，其颜色先呈紫色后变黑色，也有从白色开始发展而成凹陷疼痛的。痘疮初起时，多出现在头面部；中间阶段出现时，多集中在腹部和背部；结痂脱落后出现的，多位于足部和腿部。如果治疗稍有迟缓，就会遍布全身。至于“痘母”，就是所谓的“贼痘”或“潦浆痘”，即在正常的痘疮中潜伏一两个在旁边，形状胀大且呈蜡黄色，颜色与主痘不同。它的危害与疔疮相近，治疗方法也与治疔相差不远。
凡是痘疮中单独长得特别大，或者颜色发黑、发白，根部肿胀坚硬的，就是“痘疔”。就像疔疮实证一样，病势深重直抵筋骨；或者在黑陷的痘疮中有微微突出的尖顶，像疔疮实证一样的；或者有许多痘疮聚集在一处，形状像癣疮的；或者有黑线相连牵拉的；或者内部有一个疮口极臭极痛的，这些都是疔疮。如果没有这些症状，只是黑色的凹陷，那是“黑陷”。但是，如果黑陷结硬日久，坚硬聚拢不散，就会形成痘疔。这总归是因为气血腐坏，热毒蓄积，并结在一起，再加上受到时行疫毒之气的侵袭，属于最恶劣的证候，所以称为“疔禁”。一旦有了这种疔疮，其他的毒邪就不能宣发，痘疮也不能化脓成浆了。“疔”字的意思就是“钉”，指病情钉锢而不舒展。凡是在初起阶段，如果见到患者大便秘结，应酌情加大黄以通泄大便；外用银针挑破患处，吮吸出恶血，吐在水中，如果血色红者可以治疗，色黑者难治。随后用人乳洗净患处，将珍珠细末填入孔中，或者涂抹四圣散。更有用山慈菇和蝼蛄肉捣烂外涂，以拔取疔根的方法，这也是快捷有效的疗法。或者有用隔蒜灸法，如果毒邪很盛而患者不知疼痛，就直接在肉上灼烧艾条，灸后如果疮头红肿发作，可以再施灸。这种情况最宜紧急治疗，否则颜色逐渐变为紫暗，疼痛不安，宿疾蜂拥而起，不能灌脓，甚至导致死亡。到了结痂后痘疔溃烂成坑，内见筋骨的情况，是危重证候，适宜内服人参、桔梗、甘草梢、酒炒生地、红花、连翘、金银花、大贝母、地龙（人虫）、当归、白芍、皂角刺、赤茯苓、木通、柴胡等药物，配合外用敷药。如果毒邪内攻脏腑，变成阴疮，则难以治愈。然而，如果有毒盛而浆液清稀的症状，处于吉凶参半的时候，凡是有疔疮，如果补益托毒得当，气血恢复旺盛，那么毒邪会随着疔疮溃破排脓而宣泄出去，反而可以转祸为福。但在解毒补托之外，应用银针挑破四周，掺入珍珠、豌豆、胎发灰等药物，用油胭脂封住，使疔根溃出，这样毒邪就能随之完全去除。

The harm caused by Ding (Thorn-like sore) stems from the excessive toxicity in the blood. It forms due to Qi stagnation and heat obstruction, initially appearing purple and turning black; some cases start as white and develop into depression and pain. When pox (smallpox) first appears, it is mostly on the head and face; when it appears in the middle stage, it is mostly on the abdomen and back; when it appears after scabbing, it is mostly on the legs and thighs. If treatment is slightly delayed, it will spread all over the body. As for "Doumu" (Pox Mother), also known as "Zeidou" (Thief Pox) or "Laojiang Dou", these are one or two lesions潜伏 (latent) among normal pox lesions, characterized by swelling, enlargement, waxy yellow color, and distinct appearance from the main pox. Their harm is similar to Ding, and their treatment method is not far from that of Ding.
Whenever a pox lesion grows particularly large alone, or turns black or white, with a swollen and hard base, it is called "Douding" (Pox Thorn). Like solid-type Ding, the pathology strikes deep to the bones and muscles; or there is a slight pointed top within the black depression, resembling solid-type Ding; or many pox lesions cluster together, resembling tinea lesions; or there are black lines connecting them; or there is a single ulcer inside that is extremely foul-smelling and painful—all these are Ding. If these signs are absent, and it is merely a black depression, it is called "Heixian" (Black Depression). However, if the black depression remains hard and clustered for a long time without dispersing, it becomes Douding. This is generally due to the corruption of Qi and Blood, accumulation of heat toxicity, clustering together, combined with invasion by epidemic toxic qi, representing the most malignant condition, hence named "Dingjin" (Ding Prohibition). Once such a Ding occurs, other toxins cannot be released, and the pox cannot form pus. "Ding" means "nail," indicating that the condition is nailed shut and unable to expand. In the initial stage, if constipation is observed, Rhubarb (Dahuang) should be added appropriately to promote bowel movement; externally, an silver needle should be used to pierce the lesion, and the evil blood sucked out and spit into water—if the blood is red, it is treatable; if black, it is difficult to cure. Subsequently, wash the area with human milk, fill the hole with fine Pearl powder, or apply Sisheng San (Four Saints Powder). Another effective method is applying a paste of Smilax glabra rhizome (Shancigu) and Mole cricket (Lougu) flesh to extract the root of the Ding. Alternatively, moxibustion with garlic slices can be used; if the toxin is severe and the patient feels no pain, direct moxibustion on the flesh is performed. If after moxibustion the sore head becomes red and swollen, further moxibustion may be applied. Urgent treatment is essential; otherwise, the color will gradually turn purple and dark, pain will become incessant, old ailments will arise like swarms of bees, pus formation will fail, and death may ensue. If after scabbing the Douding ulcerates into a pit exposing bone and muscle, it is a critical condition. Internal administration of Ginseng (Renshen), Platycodon root (Jiegeng), Licorice root tip (Gancao Shao), Rehmannia glutinosa prepared with wine (Jiu Chao Shengdi), Safflower (Honghua), Forsythia fruit (Lianqiao), Honeysuckle flower (Jinyinhua), Fritillaria thunbergii bulb (Da Beimu), Earthworm (Ren Chong/Di Long), Angelica sinensis (Danggui), Peony root (Baishao), Gleditsia sinensis thorn (Jiaoci), Red Poria (Chifuling), Akebia stem (Mutong), and Bupleurum root (Chaihu) is suitable, along with external applications. If the toxin attacks the Zang-Fu organs internally, becoming a Yin sore, it is incurable. However, in cases where toxin is abundant but the pus is clear, representing a balance of good and bad omens, if the Ding is treated with appropriate tonification and expulsion support, and Qi and Blood recover vigor, the toxin will be expelled through the rupture and pus discharge of the Ding, potentially turning disaster into fortune. Besides detoxification and tonifying/expelling support, the surrounding area should be pierced with a silver needle, dusted with Pearl, pea ash, or fetal hair ash, sealed with oil-based rouge, allowing the root to emerge so that the toxic pathogen can be completely eliminated.
(The book *Yusui* establishes many names for Ding, which is somewhat overly eccentric regarding novelty. The treatment methods of Tianbu are hereby omitted.)
