胸中疼痛，气息短少，迅速进入暗处，用手遮住左眼，只用右眼注视时若能看到光亮，说明是胸中结痈。如果看不到光亮，则是瘭疽内发。如果出现吐脓血的症状，这是不治之症，应当用灰烬覆盖在脓血上，否则脓血会溅到旁人身上。另外，如果牙齿间有臭味，热血流出，这也是瘭疽，七日内死亡，治疗无效者，宜用灰烬覆盖地面的血迹。瘭疽喜欢长在手指上，与代指相似，人们分辨不清的，也称之为代指，如果不及时治疗，毒邪会顺着经脉上行，侵入脏腑导致死亡。南方人得了这种病，都斩断患指，担心毒邪向上攻入脏腑。所以瘭疽长在手指头的，起初表现为黯黑斑点，然后肿胀、发红、变黑，疼痛剧烈直达心脏。（出自《外台秘要》卷二十四）
所谓瘭疽，是肌肉中突然长出一个如豆粒或粟米大小的硬结，严重的如梅子核大小，颜色或红或黑或白或青，其下有硬核，硬核深入附着于浓肉之处，均将其割除，也可烧红铁器烙烫患处，使其焦枯如炭，或在黯黑斑点处灸一百壮为佳，早春采集酸模叶薄敷四周，以防其蔓延。饮用葵根汁、犀角汁、升麻汁以折退热势，内外治疗均依据丹毒的方法进行。（出自《肘后备急方》卷五）
有一种缓疽，初起时肿块形状似痈，没有头尾之分，颜色无异，只是疼痛，深处有根基硬核，又与皮肉紧密相连，除此之外别无其他特征，一名为内痈。大的如拳头，小的如桃李状，多日不消退，容易变为紫色黯黑，日久则皮肉全部腐烂。初期服用五香连翘汤以去血，用小豆粉薄涂患处，其间多次针刺放血，再薄涂药粉，以求消散；如果不能消散，颜色未变青黯的，用炼石粉薄涂；如果延误时机未能及时治疗，已经溃烂的，仍服用五香连翘汤及漏芦汤泻下，待青色恶肉去除干净便停药，好肉自然生长，只需敷升麻膏即可，若不生长，单敷一味黄柏散；如果敷白蔹散，多日后青色恶肉未尽者，可用漆头赤皮白蔹取半钱匕，混合三大钱匕白蔹散中，调和后敷用，恶肉去尽后，再用纯白蔹散敷贴，看到好肉欲生时，可敷黄柏散。黄柏散方、白蔹散方、漆头白蔹散方，均为单味药单独使用，根据用量捣筛成散剂。（出自《外台秘要》卷二十四）
治疗发背的方剂。
取活蜗牛一百个，放入一升容量的洁净瓶中，用新汲取的一盏水浸泡瓶中并密封系紧，从晚上直到第二天早晨取出蜗牛放置一旁，瓶中的水如同涎液，将真蛤粉不限多少随时调匀敷贴，用雏鸟羽毛扫拭疮面，每天可进行十余次，热痛停止，疮口即可痊愈。（出自《证类本草》卷二十一）
Chest pain, shortness of breath, rapidly entering a dark place, covering the left eye with hand, and if looking with only the right eye one can see light, it indicates a chest carbuncle (chest abscess). If no light is seen, it is an internal onset of Zhongju (acute infectious skin disease). If vomiting pus and blood occurs, this is an incurable disease; ash should be applied to cover the pus and blood, otherwise it will splash onto bystanders. Additionally, foul odor from between teeth and bleeding of hot blood indicate Zhongju, leading to death within seven days; if treatment fails, ash should be covered on the ground where blood fell. Zhongju tends to affect fingers, resembling Daizhi (paronychia); when indistinguishable, it is also called Daizhi. Without prompt treatment, toxic pathogens ascend along meridians, invading zang organs and causing death. People in the South amputate the affected finger upon contracting this disease, fearing upward invasion of toxins into the zang organs. Thus, for Zhongju on fingertips: initially presenting as dark spots, followed by swelling, redness, turning black, with severe pain reaching the heart. (From *Waitai Miyao*, Vol. 24)
Zhongju refers to a sudden formation in the flesh, like a bean or millet seed; severe cases resemble a plum pit. Colors may be red, black, white, or green, with a hard core beneath that penetrates deeply into fleshy areas. These should be excised, or cauterized with heated iron until charred like charcoal. Moxibustion of 100 moxa cones on the dark spot is optimal. In early spring, thin leaves of Rumex acetosa (Suanmo Ye) should be applied around the periphery to prevent spread. Drinking juice from Abutilon theophrasti root (Kuigen), Rhinoceros Horn (Xijiao), or Cimicifuga herba (Shengma) helps reduce heat. Internal and external treatments follow the methods for Dan Du (erysipelas/toxic heat rash). (From *Zhouhou Beiji Fang*, Vol. 5)
Huanju (slow abscess) begins as a swelling resembling a carbuncle, without distinct head or tail, with normal color but painful, having a deep-rooted hard core adhering closely to skin and flesh, also known as Nei Yong (internal carbuncle). Large ones are fist-sized, small ones like peach or plum fruits. They persist for days without resolving, often turning purple-black, eventually causing complete rotting of skin and flesh. Initially, Wuxiang Lianqiao Tang (Five-Spice Forsythia Decoction) is taken to remove blood, followed by thin application of Adzuki bean powder. Multiple needle pricks to release blood are repeated with powder application to achieve resolution. If unresolved and color has not turned blue-black, refined stone powder is applied. If treatment is delayed and ulceration occurs, Wuxiang Lianqiao Tang and Loulu Tang (Euphorbia Decoction) are administered to purge, stopping once blue-black necrotic tissue is cleared. Healthy flesh regenerates naturally; Shengma Gao (Cimicifuga Ointment) is beneficial. If healing fails, Huangbai San (Phellodendron Powder) alone is used. If Bailian San (Ampelopsis Powder) is applied and necrotic tissue persists after many days, half a qian-bi of Ampelopsis with lac-coated red skin is mixed with three qian-bi of Bailian San, applied topically. Once necrotic tissue is fully removed, pure Bailian San is used. When healthy flesh begins to regenerate, Huangbai San is applied. Formulas for Huangbai San, Bailian San, and Lac-Coated Ampelopsis San consist of single herbs processed into powder according to dosage. (From *Waitai Miyao*, Vol. 24)
Formula for treating Fabei (back carbuncle).
Take 100 live snails, place them in a clean one-sheng bottle, add one zhen of freshly drawn water, seal tightly, and leave from evening until morning. Remove snails; the remaining liquid resembles saliva. Mix real clam powder (Gefen) in appropriate amounts, apply thinly to the wound, sweep with chick feathers. Repeat over ten times daily. Heat and pain cease, and the wound heals. (From *Zhenglei Bencao*, Vol. 21)
