井疽生于心窝，乃任脉经鸠尾穴，又名穿心毒，最为难治。此因心火妄动而发。若初起
状如黄豆，即 赤高肿，心躁烦而肌热如焚，唇干舌燥黄色，渴饮冷水，斯时或以凉膈散通
腑泻热，或用犀角地黄汤清营解毒。若得疮势渐退，自可调理而愈。如或坚硬紫黑，毒瓦斯内
陷，恶闻食臭，呕吐不宁，精神恍惚，腹胀泄泻者，不治。又有起时肿硬，肉色不变，积
久穿溃者，此名穿心冷 。乃因多食生冷死厌之物，恶毒积久，内犯心包络，故外发于心掩
也。宜以温补气血之剂治之。
心漏者，初时胸间生疮，因不慎酒色，致成漏窍，每每流血，久则神形困惫，腰痛难伸
，行同伛偻。此其疡虽属心，根由于肾；夫心肾本相通也，心气必得肾气以相生，肾气必得
心气以相闭。心漏之成，成于肾气之泄，安可不补肾气之衰乎？然补肾而心气不闭，则补肾
无益，盖有出气而无止气耳。或云漏疮多成于湿热，今补肾而不闭心窍，则漏不愈；闭心窍
而不去湿热，只治心肾，漏亦不能愈也。然漏亦不同，漏在他处者，可泄其湿热；在胸间者
，不可泄湿热也。盖漏既成于肾虚，肾虚则寒而非热也；肾虚者，肾水虚而非邪水盛也。补
真阴而邪水自消，温肾寒而湿热自退矣。温肾丸主之∶鹿茸二具去毛，酥炙，附子二枚，泡
去皮脐，人参、青盐各二两，瓦松二枝，红枣四两。煮枣捣丸。每空心酒下三十丸，服月愈
而漏自愈。一方无瓦松、人参。此方兼治肾虚腰痛如神。
井疽生于心窝部位，位于任脉的鸠尾穴处，又名穿心毒，是最难治疗的病症。这是因为心火妄动而引发的。如果初起时形状像黄豆，随即红肿高突，心中烦躁不安，肌肤发热如火烧，嘴唇干燥，舌苔黄燥，口渴想喝冷水，此时可以用凉膈散来通腑泻热，或者用犀角地黄汤来清营解毒。如果疮势逐渐消退，自然可以通过调理而痊愈。假如疮口坚硬呈紫黑色，毒气内陷，厌恶闻到食物的气味，呕吐不止，精神恍惚，腹部胀满并伴有腹泻的，属于不治之症。又有初起时肿胀坚硬，皮肤颜色不变，日久破溃流脓的，这名叫穿心冷漏。这是由于多吃生冷、腐败变质的食物，恶毒之气积聚日久，内犯心包络，所以外发于心胸部位。应当用温补气血的方剂治疗。
心漏病，起初在胸部生疮，因为不慎节制酒色，导致形成漏窍，经常流血，时间久了则神志和形体困倦疲惫，腰部疼痛难以伸展，行走姿态如同驼背。这个疮疡虽然属于心的病变，但根源在于肾；心和肾本是相通的，心气必须得到肾气的相生才能旺盛，肾气必须得到心气的固摄才能闭藏。心漏的形成，是由于肾气泄越所致，怎么能不补肾气的衰弱呢？然而，如果只补肾而心气不能固闭，那么补肾就没有益处，这就像只有气体排出而没有止住气体一样。有人说漏疮多由湿热引起，现在补肾而不闭锁心窍，则漏疮不会痊愈；闭锁心窍而不清除湿热，只治疗心肾，漏疮也不能痊愈。但是漏疮的情况并不相同，发生在身体其他部位的漏疮，可以清泄湿热；发生在胸部的漏疮，不可以清泄湿热。因为漏疮既然形成于肾虚，肾虚则是寒证而不是热证；肾虚是指肾阴（真阴）亏虚，而不是邪水（湿浊）亢盛。补益真阴则邪水自然消除，温补肾阳则湿热自然退去。主治方剂为温肾丸：鹿茸二具（去毛，用酥油炙烤），附子二枚（炮制，去皮及脐），人参、青盐各二两，瓦松二枝，红枣四两。将煮烂的红枣捣碎制成丸药。每次空腹时用酒送服三十丸，服药一个月后病情痊愈，漏疮也自愈。另一版本方剂中没有瓦松和人参。此方兼治肾虚腰痛，效果神奇。
Jing Ju (Well Carbuncle) arises in the epigastric region, located at the Jiutui (CV15) acupoint of the Ren Mai (Conception Vessel), also known as Chuan Xin Du (Penetrating Heart Toxin). It is the most difficult condition to treat. This occurs due to the reckless movement of Heart Fire. If, at the onset, it resembles a soybean and subsequently becomes red, swollen, and elevated, accompanied by mental restlessness, feverish sensation of the skin like burning, dry lips, yellow and dry tongue coating, and thirst for cold water, one may use Liang Ge San (Cool the Diaphragm Powder) to unblock the fu-organs and purge heat, or use Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) to clear the Ying (Nutritive) level and detoxify. If the course of the sore gradually recedes, recovery can be achieved through regulation. However, if the lesion becomes hard, purple, and black, with toxin sinking inward, aversion to food odors, incessant vomiting, mental confusion, abdominal distension, and diarrhea, it is incurable. Another type presents with initial swelling and hardness, unchanged skin color, which eventually ulcerates after a long period; this is named Chuan Xin Leng Lou (Penetrating Heart Cold Fistula). It is caused by consuming excessive amounts of raw, cold, and spoiled foods, allowing toxic accumulation over time to invade the Pericardium Luo (Collateral), thus manifesting externally on the heart/chest area. It should be treated with decoctions that warm and tonify Qi and Blood.
Xin Lou (Heart Fistula) initially presents as a sore in the chest. Due to lack of restraint regarding alcohol and sexual activity, a fistulous tract forms, often bleeding. Over time, the spirit and physical form become exhausted, lower back pain makes extension difficult, and gait resembles kyphosis. Although this external sore belongs to the Heart, its root lies in the Kidney; the Heart and Kidney are originally connected. Heart Qi must receive mutual generation from Kidney Qi, and Kidney Qi must receive mutual closure (consolidation) from Heart Qi. The formation of Heart Fistula results from the leakage of Kidney Qi; therefore, how can one fail to tonify the deficiency of Kidney Qi? However, if one tonifies the Kidney without closing/consolidating the Heart Qi, tonification is of no benefit, akin to having outflow without inflow control. Some say fistulas mostly result from Damp-Heat. Now, if one tonifies the Kidney without closing the Heart orifice, the fistula will not heal; if one closes the Heart orifice without eliminating Damp-Heat, treating only Heart and Kidney will not cure the fistula either. Yet, fistulas differ by location. Fistulas elsewhere can have their Damp-Heat drained; those in the chest cannot. Since the fistula forms due to Kidney Deficiency, Kidney Deficiency implies Cold rather than Heat; Kidney Deficiency refers to the deficiency of True Yin (Kidney Water) rather than the excess of pathogenic Water (Dampness). Tonifying True Yin causes pathogenic water to dissipate naturally; warming Kidney Cold causes Damp-Heat to retreat naturally. The principal formula is Wen Shen Wan (Warm Kidney Pill): Lu Rong (Cervus Nippon Cornu, Deer Antler) two pieces (de-haired, fried with butter), Fu Zi (Aconiti Lateralis Radix Praeparata, Prepared Aconite Root) two pieces (processed, peel and umbilicus removed), Ren Shen (Ginseng Radix et Rhizoma), Qing Yan (Natrii Chloridum, Rock Salt) each two liang, Wa Song (Parmelia Soredians, Rock Moss) two branches, Hong Zao (Zizyphi Fructus, Jujube Fruit) four liang. Boil the jujubes, mash them, and make pills. Take thirty pills orally with wine on an empty stomach; after one month of administration, the illness heals and the fistula self-cures. An alternative version excludes Wa Song and Ren Shen. This formula also treats lower back pain due to Kidney Deficiency with miraculous effect.
