（收靥门参看）
〔万〕痘疮所贵者，坚实不破，圆净成痂也，其有溃烂者，火胜也。经曰∶热胜
则肉腐。火之为用，猛虐峻暴，近之则燥痒不宁，迫之则焦痛难忍，灼之则糜烂成疮，故败物者莫如火也。火生
于空，非虚不燃，乘之以风，其焰益烈，痘疮溃烂，由肌肉素虚，邪风侵袭，风者，善行数变，行诸脉俞，散
于荣卫之间，一旦毒发于里，风应于表，风火相扇，肌肉愤 ，皮肤决裂，而疮坏矣。如脓成而溃，则毒已
化，但粘衣渍席，不能干较，古方以败草散主之，诚良法也。脓浆未成，其毒未化，痒破溃烂者，则卫气暴泄，
津液不荣，譬诸草木剥削其皮，枯萎而死矣。经曰∶根于中者，命曰神机，神去则机息，根于外者，命曰气立，
气止则化绝，此之谓也。
〔薛〕闻人氏云∶痘 烂之证，因当发散而不发散，则毒瓦斯闭塞，以致喘促闷乱。不当发散而误发散，则
毒随阳气暴出于外，遍身皮肤溃烂。治宜调脾胃，进饮食，大便调和，荣卫健旺，毒瓦斯自解，而无目赤咽痛，口疮
吐衄等证。窃谓，前证若发表过甚，大便自利，急用理中丸、豆蔻丸（俱痘泻利）以救其里。亦有痘疹如蚊
所啮而色黑，乃危证也，若大小便秘结烦躁，用山栀子汤（痘夹 ）、 猪尾血调脑子治之，自利不食者
不可用。盖毒发于表而妄汗之，则腠理开泄，荣卫益虚，转增疮烂，由是风邪乘虚
变证者有之。若毒根于里而妄下之，则内气愈虚，毒不能出而反入焉，由是土不胜水，变黑归肾，身体振寒，
两耳尻冷，眼合肚胀，其疮黑陷，十无一生，治者审之。
疮出太盛，脓汁淋漓，不可着席，疼痛者干黄土罗末敷之，甚者白龙散（痒塌）帛裹扑之，或败草散（收靥）
贴之。丹溪云∶疮湿者，用泻湿，乃肌表间湿，宜用风药白芷、防风之类。闻人氏用麦麸衬卧。暑月热，甚
当藉之以芭蕉叶为佳。或疮已出定，大便不通，而脓汁不干者，此热毒合下证也，宜牛黄丹利之。若疮口湿，
及脓血杂流者，百花膏（收靥）、生肌散、金华散、绵茧散（收靥）、魏氏白螺散、乳香韶粉散俱可
用。若靥后复生，乃余毒失于解利，留滞于肌肉之间而然也，宜消毒散（出太密）。或结痂久而不落，亦宜百
花膏。若痘烂无脓，吐利不止，或二便下血，乳食不化者，不治之证也。
牛黄丹 治疮子出定，大便不通，疮中脓水不干。
牛黄 大黄末（生用） 珍珠末 粉霜（各一两）
上研匀，炼蜜丸，如黍米大。每服十粒，人参汤下。量儿大小加减。

[Wan Quan] The most desirable outcome for smallpox is that it remains firm, unbroken, round, and clean, eventually forming a scab. Cases involving ulceration are caused by excessive Fire pathogen. The classics state: "When Heat prevails, flesh rots." The function of Fire is fierce and violent; proximity causes dryness, itching, and restlessness; pressure causes burning pain that is unbearable; scorching leads to erosion and sore formation. Thus, nothing destroys matter more effectively than Fire. Fire arises from emptiness and cannot burn without void space; when driven by Wind, its flames intensify. Smallpox ulceration occurs due to pre-existing deficiency in muscle tissue, allowing Evil Wind to invade. Wind is characterized by rapid movement and change, traveling through meridians and acupoints, dispersing between Ying (Nutritive) and Wei (Defensive) levels. Once toxins erupt internally and Wind responds externally, Wind and Fire fan each other, causing muscles to swell and rupture, skin to crack, and sores to deteriorate. If pus forms and then ruptures, the toxin has transformed; the issue is merely that it sticks to clothes and mats, making drying difficult. Ancient formulas use Baicao San (Decoction of Decayed Grass) as the primary treatment, which is indeed an excellent method. If pus has not formed and the toxin has not transformed, scratching due to itching leads to ulceration; this represents a sudden leakage of Wei Qi and failure of body fluids to nourish the skin, akin to plants stripped of their bark, withering and dying. The classics state: "Those rooted within are called Shen Ji (Spirit Mechanism); if Spirit departs, mechanisms cease. Those rooted externally are called Qi Li (Qi Establishment); if Qi stops, transformation ends." This refers to such cases.
[Xue Ji] Wenren Shi stated: In cases of smallpox ulceration, if dispersion should have been employed but was not, toxic vapors become blocked, leading to panting, distress, and confusion. If dispersion is mistakenly used when inappropriate, toxic vapors surge outward with Yang Qi, causing widespread skin ulceration. Treatment should focus on regulating the Spleen and Stomach, promoting appetite, harmonizing bowel movements, and strengthening Ying and Wei, allowing toxic vapors to resolve naturally, thereby preventing symptoms like red eyes, sore throat, mouth ulcers, vomiting, or epistaxis. I believe that if the aforementioned condition results from excessive exterior-releasing methods leading to spontaneous diarrhea, one must urgently use Lizhong Wan (Regulate the Middle Pill) or Doukou Wan (Cardamom Pill) [both indicated for post-smallpox diarrhea] to rescue the interior. There are also cases where smallpox lesions resemble mosquito bites and turn black, indicating a critical condition. If accompanied by constipation of both stool and urine, irritability, and restlessness, Shanzhizi Tang (Gardenia Decoction) [for smallpox with macules] mixed with pig tail blood and brain can be used; however, it is contraindicated in cases of spontaneous diarrhea and anorexia. Releasing the exterior with sweating when toxins are at the surface opens the pores, further depleting Ying and Wei, exacerbating ulceration, and allowing Wind-Evil to enter due to deficiency, causing complications. Conversely, purging when toxins are rooted internally further depletes internal Qi, trapping toxins inside rather than expelling them. This leads to Earth failing to control Water, turning black and returning to the Kidney, manifesting as shivering chills, cold ears and buttocks, closed eyes, abdominal distension, and blackened, depressed sores. Such cases are almost invariably fatal; physicians must exercise caution.
If sores are excessively numerous with dripping pus, unable to touch the mat, and painful, apply fine powder of dry yellow earth. For severe cases, apply Bailong San (White Dragon Powder) [indicated for itchy collapse] wrapped in cloth, or Baicao San [indicated for scab formation]. Danxi stated: For moist sores, use damp-draining methods, as this is dampness on the muscle-surface, suitable for aromatic wind-dispersing herbs like Bai Zhi (Angelicae Dahuricae Radix) and Fang Feng (Saposhnikoviae Radix). Wenren Shi recommended using wheat bran as bedding. During hot summer months, using banana leaves as a lining is highly advisable. If sores have erupted but defecation is obstructed and pus does not dry, this indicates heat-toxin combined with a downward-indicating syndrome; Niuhuang Dan (Calculus Bovis Pill) should be used to promote evacuation. For moist sore openings and mixed discharge of pus and blood, Baihua Gao (Hundred Flowers Ointment), Shengji San (Generate Flesh Powder), Jinhua San (Golden Splendor Powder), Mianjian San (Silkworm Cocoon Powder), Wei's Bailuo San (White Snail Shell Powder), and Ruxiang Shaofen San (Frankincense and Kaolin Powder) are all applicable. Recurrence after scabbing is due to residual toxins failing to be cleared, lingering in the muscle layer; Xiaodu San (Detoxification Powder) [for overly dense eruptions] is appropriate. If scabs persist for a long time without falling off, Baihua Gao is also suitable. However, if smallpox ulceration presents with no pus, continuous vomiting and diarrhea, bleeding from bowels or urethra, and inability to digest milk/food, it is an untreatable condition.
