申斗垣曰∶肺疽即天火疮，乃任脉之经，当胸而生。在紫宫、玉堂之穴，十日
可刺，脓水黄白色者可治。如无脓渐大，旁攻上硬下虚，自破流水不绝，咳唾引痛者死。（《启玄》）

王肯堂曰∶膻中疽，生心窝上两乳中间，属任脉经膻中穴。盖膻中为气之海，气
所居焉，能分布阴阳，若脏腑阴阳不和，七情不平，则发此证。稍迟则溃烂，恶证多
者难治。（《准绳》）

《灵枢》云∶发于胸名曰井疽，其状大如豆，三四日起不治，下入腹不治，七日死矣。
王肯堂曰∶心窝生疽，初起如黄豆，肉色不变，名曰井疽，又名穿心冷 。若冷
气攻心，精神恍惚，呕吐冷痰，恶闻食臭，毒瓦斯内陷，腹胀满者不治；若心燥如火，肌
热如焚，不时盗汗，唇焦舌干黄色，渴饮冷水者，是正候也。（《准绳》）
申斗垣曰∶井疽，又名心漏疽，又名穿心毒。最为难治。有经年不愈者，乃多
食生冷死厌之物，恶毒积久，内犯心包络，
故外发于心掩也，乃心胃两经受证。治同痈疽法。（《启玄》）

汪省之曰∶井疽乃任脉之经，在鸠尾穴，状如大豆。三四日间，若不早治，十
日必死。外发者生，内陷者死。（《理例》）
申斗垣说：肺疽就是天火疮，属于任脉的经络，生长在胸部。位于紫宫穴、玉堂穴的位置，发病十日内可以施针，如果脓液和渗出液呈黄白色的是可治之症。如果没有脓液且肿块逐渐增大，旁边坚硬上部肿胀下部虚弱，自行破溃后流水不止，咳嗽吐痰时牵引疼痛的是死证。（出自《启玄》）
王肯堂说：膻中疽，生长在心窝上方两乳之间，属于任脉经络的膻中穴。因为膻中是气的海，气居住的地方，能够分布阴阳，如果脏腑阴阳不和，七情波动不平，就会引发这种病症。拖延时间则会溃烂，出现恶证多的难以治疗。（出自《准绳》）
《灵枢》说：发生在胸部的疽叫做井疽，它的形状像豆子一样大，三四天起病如果不治疗，毒邪下入腹部则不治，七天就会死亡。
王肯堂说：心窝处生疽，初起时像黄豆大小，皮肤颜色没有变化，叫做井疽，又叫做穿心冷。如果冷气攻心，精神恍惚，呕吐冷痰，厌恶闻到食物的气味，毒瓦斯内陷，腹胀满的是不治之症；如果心中燥热如火，肌肤发热如焚烧，不时盗汗，嘴唇焦裂舌头干燥发黄，想喝冷水的是正候（典型症状）。（出自《准绳》）
申斗垣说：井疽，又叫做心漏疽，又叫做穿心毒。最为难治。有常年不愈的，是因为多吃生冷厌食之物，恶毒积聚日久，内犯心包络，所以外发于心掩盖之处，这是心和胃两条经脉受证的反应。治疗方法同痈疽法相同。（出自《启玄》）
汪省之说：井疽属于任脉的经络，在鸠尾穴，形状像大豆。三四天之间，如果不早治疗，十天必定死亡。向外发的能生，向内陷的会死。（出自《理例》）
Shen Douyuan stated: Feiju (Lung Carbuncle) is also known as Tianhuochuang (Heavenly Fire Sore). It belongs to the Ren Mai (Conception Vessel) meridian and arises on the chest. Located at the Zigong (Purple Palace) and Yutang (Jade Hall) acupoints, it can be punctured within ten days of onset. If the pus and exudate are yellowish-white, the condition is treatable. If there is no pus and the swelling gradually enlarges, with hardness on the sides, upper fullness, and lower deficiency, spontaneous rupture with continuous discharge of fluid, and pain triggered by coughing and expectoration, indicates a fatal prognosis. (From *Qixuan*)
Wang Kentang stated: Shanzhongju (Shanzhong Carbuncle) arises between the two breasts above the epigastric region. It belongs to the Shanzhong (Chest Center) acupoint of the Ren Mai (Conception Vessel) meridian. Since Shanzhong is the Sea of Qi, where Qi resides and distributes Yin and Yang, disharmony of Yin and Yang in the Zang-Fu organs or imbalance of the Seven Emotions can trigger this syndrome. Delayed treatment leads to ulceration; cases with multiple malignant signs are difficult to treat. (From *Zhunsheng*)
The *Lingshu* (Spiritual Pivot) states: A carbuncle arising in the chest is called Jingju (Well Carbuncle). Its appearance is like a bean. If untreated from the third or fourth day, and if the pathogen sinks into the abdomen, it becomes incurable, leading to death within seven days.
Wang Kentang stated: A carbuncle arising in the epigastric region, initially resembling a soybean in size with unchanged skin color, is called Jingju (Well Carbuncle), also known as Chuanxin Leng (Piercing Heart Cold). If cold pathogenic factors attack the Heart, causing mental confusion, vomiting of cold phlegm, aversion to food odors, internal sinking of toxic heat, and abdominal distension, it is incurable. If there is inner dryness and heat like fire, skin fever like burning, frequent night sweats, cracked lips, dry yellow tongue, and thirst for cold water, these are the typical manifestations. (From *Zhunsheng*)
Shen Douyuan stated: Jingju (Well Carbuncle) is also known as Xinlouju (Heart Fistula Carbuncle) or Chuanxindu (Piercing Heart Toxin). It is extremely difficult to treat. Some cases persist for years due to excessive consumption of raw, cold, and unappetizing foods, causing accumulated toxicity that internally invades the Pericardium Luo (Connecting Vessels). Thus, it manifests externally covering the Heart area, representing syndromes of both the Heart and Stomach meridians. The treatment follows the same principles as Yongju (Carbuncles and Ulcers). (From *Qixuan*)
Wang Shengzhi stated: Jingju (Well Carbuncle) belongs to the Ren Mai (Conception Vessel) meridian, located at the Jiutui (Tailbone Tip) acupoint, appearing like a large soybean. Within three to four days, if not treated early, death will occur within ten days. External manifestation indicates survival; internal sinking indicates death. (From *Lili*)
