凡素常遇漆味即患漆疮者 川椒三四十粒捣碎，涂口鼻上，即不能为害。
王肯堂曰∶恶疮，诸痛痒疮，皆属于心，诸湿肿满，皆属于脾，心主血，脾主
肉，血热而肉湿，湿热相合，溃败肌肤，浸淫不休，不可以定名命之，故谓之恶疮也。
然有辨焉，如疥癣瘾疹之属，拂郁气血，在皮肤腠理间者，可以表而散，《内经》有谓
汗之则疮已是矣。若郁气血在肌肉之分，外达皮肤，作寒热而生脓者，或七情所招，或
膏粱之变，皆宜解内热，不宜汗也，张仲景所谓疮家不可发汗，汗之则痉者是矣，一
疮而有宜汗不宜汗之戒，盖热有浅深表里故也。故疮在皮肤，则当因其轻而扬之，汗
之浴之，外以杀虫润燥，皆解凝结涎沫之药敷之；疮之在肌肉，则当因其重而减之，
泻经络之热，清凉气血，外以化脓生肌膏 之；疮在头巅则当射而取之，须酒制寒
凉剂，更以风药升而上之，外以杀虫解热药敷之。能明此三者，其于治疮思过半矣。（《准绳》）

凡是平时遇到漆的气味就会患漆疮的人，川椒三四十粒捣碎，涂抹在口鼻上，就能避免受害。
王肯堂说：恶疮，各种疼痛瘙痒的疮疡，都归属于心；各种湿肿胀满，都归属于脾。心主血，脾主肉，血热而肉湿，湿热相结合，导致肌肤溃败，浸淫不止，无法确定具体名称来命名，所以称之为恶疮。
然而需要辨别，如疥癣瘾疹这类，是气血拂郁，位于皮肤腠理之间的，可以用发汗的方法使邪气从表解散，《内经》有说“发汗则疮已”的道理。如果气血郁结在肌肉的分野，向外达于皮肤，出现寒热并化脓的情况，或者是七情所伤，或者是饮食膏粱厚味的变化引起的，都应当清解内热，不宜发汗，这就是张仲景所说的疮家不可发汗，发汗就会导致痉病的情况。一个疮病却有宜汗和不宜汗的禁忌，是因为热邪有浅深表里之分。所以疮在皮肤，就应当顺着其轻浅的特性而发散它，发汗沐浴，外用杀虫润燥的药物，以及解凝结涎沫的药物外敷；疮在肌肉，就应当顺着其沉重的特性而削减它，泻除经络的热邪，清凉气血，外用化脓生肌膏外敷；疮在头顶，就应当用射法取之，需用酒制的寒凉药剂，再用风药升提而上，外用杀虫解热的药物外敷。能明白这三点，治疗疮病的道理就掌握了一半了。（出自《医学准绳六要》）

Wang Kentang stated: "All painful, itching sores and ulcers belong to the Heart; all dampness, swelling, and fullness belong to the Spleen. The Heart governs Blood, and the Spleen governs Flesh. When Blood is hot and Flesh is damp, damp-heat combines, causing skin and muscle to ulcerate and exude ceaselessly. Since it cannot be named specifically, it is called 'E Chuang' (Malignant Ulcer)."
However, differentiation is necessary. Conditions such as scabies, tinea, and urticaria involve stagnation of Qi and Blood in the skin and interstices; these can be resolved by releasing the exterior through sweating, as stated in the *Neijing*: "Sweating cures sores." If Qi and Blood stagnation is located in the muscle layer, extending outward to the skin, presenting with chills, fever, and pus formation, whether caused by emotional disturbances or dietary excesses of rich/greasy foods, one should clear internal heat rather than induce sweating. This aligns with Zhang Zhongjing's principle that patients with sores should not be sweated, as sweating leads to spasms. Thus, there are contraindications regarding sweating for different sores because heat has varying depths and locations (exterior vs. interior). Therefore, if the sore is in the skin, treat its lightness by dispersing it via sweating and bathing, and externally apply insecticidal and moisturizing agents, as well as drugs resolving condensed phlegm and foam. If the sore is in the muscle, treat its heaviness by reducing it, clearing heat from the meridians, cooling Blood and Qi, and externally applying ointments that promote pus discharge and tissue regeneration. If the sore is on the vertex of the head, use shooting methods to extract it, employing cold-natured herbs processed with wine, combined with wind-dispelling herbs to ascend, and externally apply insecticidal and heat-clearing agents. Understanding these three principles covers more than half of the treatment of sores. (From *Yi Xue Zhun Sheng*)
