胸发疽生于正胸堂，去结喉三寸，与心窝不远，乃手足六经交会之所，其患最凶，丧人
性命，宜速治之。若三、四日失治，则皮开肉裂，甚可畏也。宜用牛黄、熊胆研细，香油调
涂四边弦上，以免开花。如痛甚，用乳香、没药为末，铺粗纸上，外以青布片卷好，蘸清油
点火，在疮四围照之，痛自止矣。内服蟾酥丸、活命饮，以消散之。若便秘脉实者，即与凉
膈散通腑泄热；成功后，托里消毒；溃，则用八珍、十全等补剂敛口。
膻中疽生心窝上、两乳中间，属任脉膻中穴。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，则发此毒。初亦服蟾酥丸、活命饮；若肿硬发热作呕，大便
秘结，烦躁饮冷，舌干口苦，六脉沉实有力，宜服内疏黄连汤，以内除之，使邪气不致传变
归心则吉。余如前证治法。
甘疽，生于乳上肉高耸处，属肺经中府穴之下。无论左右，皆由忧思气结而成。治法同
上。
人有久嗽后肺受损伤，皮肤黄瘦，毛悴色焦，咽喉雌哑，寒热往来，自汗盗汗，气喘不
得卧，小便数而不渴，口中有浊唾痰沫而无脓，寸口脉数而虚涩者，此为肺痿。人有胸膈间
作痛，咽干口燥而渴，喘急不得安卧，咳嗽不止，吐痰便觉疼甚，按之更增气急，痛不可忍
，四肢微肿，喉间闻腥臭之气，随吐脓血，胸前皮肤甲错，肉微起，其人能右睡而不能左卧
，左卧即喘急不安，脉数而有力者，此为肺痈。痿者，萎也，如草木之萎而不荣，为津亡而
气竭也；痈者，壅也，肺气郁逆，久壅而成也。盖肺为五脏华盖，处于胸中，主于气，候于
皮毛。凡劳伤血气，腠理虚而风邪乘之，内感于肺，则汗出恶风，咳嗽短气，鼻塞项强，胸
胁胀满，久而不瘥，便成肺痿；又或汗下过多，重亡津液，亦能致之。若其风中于卫，呼气
不入，热逼于荣，吸气不出，风伤皮毛，热伤血脉，风热相搏，气血稽留，蕴结于肺，久则
变为肺痈；至如房欲不节，肾水亏而虚火上炎，又或醇酒炙 ，辛辣浓味，熏蒸于肺，
无不可成痈也。然痿为正气虚，痈为邪气实。正气虚者，治之宜缓；邪气实者，治之宜速；
虚则宜补中带清，实则宜补中用泻。治痿，宜清燥救肺汤；治痈，则未溃者，宜葶苈大枣泻
肺汤，或千金苇茎汤；其已溃者，宜内补黄 汤。
胸发疽生于正胸堂，距离结喉三寸，与心窝不远，是手足六经交会的地方，病情最凶险，危及生命，应当迅速治疗。如果三、四天失治，就会皮开肉裂，非常可怕。应该用牛黄、熊胆研成细末，用香油调和涂抹在疮口四周的边缘，以避免溃烂开花。如果疼痛剧烈，用乳香、没药研成粉末，铺在粗纸上，外面用青布片卷好，蘸清油点燃，在疮口周围照射，疼痛自然停止。内服蟾酥丸、仙方活命饮，以消散毒邪。如果便秘脉实，就给予凉膈散通腑泄热；脓成之后，用托里消毒散；溃破后，用八珍汤、十全大补汤等补剂收敛伤口。
膻中疽生在心窝上、两乳中间，属于任脉的膻中穴。因为膻中是气之海，气居住在这里，能分布阴阳。如果脏腑阴阳不和，七情不平，就会发生这种毒证。初期也服用蟾酥丸、仙方活命饮；如果肿硬发热作呕，大便秘结，烦躁想喝冷水，舌干口苦，六脉沉实有力，适宜服用内疏黄连汤，从内部清除邪气，使邪气不致传变归心则吉利。其余如前证治法。
甘疽，生于乳上肉高耸处，属于肺经中府穴之下。无论左右，都是由忧思气结而成。治疗方法同上。
有人久咳后肺部受损，皮肤黄瘦，毛发憔悴面色枯焦，咽喉声音嘶哑，寒热往来，自汗盗汗，气喘不能平卧，小便频数但不口渴，口中有浊唾痰沫而无脓，寸口脉数而虚涩，这是肺痿。有人胸膈间作痛，咽干口燥而渴，喘急不能安卧，咳嗽不止，吐痰时觉得疼痛厉害，按压后更增加气急，痛不可忍，四肢微肿，喉间闻到腥臭之气，随吐脓血，胸前皮肤粗糙如鳞甲，肌肉微起，这个人能右侧睡而不能左侧卧，左侧卧即喘急不安，脉数而有力，这是肺痈。痿，就是萎，像草木枯萎而不茂盛，是因为津液亡失而气竭；痈，就是壅，肺气郁逆，久壅而成。因为肺是五脏的华盖，处于胸中，主司气，反映于皮毛。凡是劳伤血气，腠理空虚而风邪乘虚而入，内感于肺，就会汗出恶风，咳嗽短气，鼻塞项强，胸胁胀满，久而不愈，便成为肺痿；或者又或汗下过多，重伤津液，也能导致此病。如果风邪中于卫分，呼气不入，热邪逼于营分，吸气不出，风伤皮毛，热伤血脉，风热相搏，气血稽留，蕴结于肺，久则变为肺痈；至于房事不节，肾水亏虚而虚火上炎，或者又或饮用醇酒炙烤辛辣浓味食物，熏蒸于肺，没有不能成痈的。然而痿是正气虚，痈是邪气实。正气虚者，治疗宜缓；邪气实者，治疗宜速；虚则宜补中带清，实则宜补中用泻。治疗肺痿，适宜用清燥救肺汤；治疗肺痈，未溃破者，适宜用葶苈大枣泻肺汤，或者千金苇茎汤；已经溃破者，适宜用内补黄芪汤。
The chest carbuncle (chest fa ju) arises in the center of the chest, three cun below the laryngeal prominence (Jiehou), not far from the heart pit. It is the intersection of the six meridians of the hands and feet. The condition is most severe and life-threatening, requiring prompt treatment. If left untreated for three or four days, the skin may split and flesh crack, which is extremely alarming. One should use powdered Niuhuang (Calculus Bovis, 牛黄) and Xiongdan (Ursus Bile, 熊胆), mixed with sesame oil, and apply it to the periphery of the lesion to prevent ulceration ("blooming"). If pain is severe, use powder of Rushiang (Boswelliae Carthartici Resina, 乳香) and Moyao (Myrrhae Resina, 没药), spread on coarse paper, wrapped in a piece of blue cloth, dipped in clear oil, ignited, and held around the wound to irradiate it; the pain will cease spontaneously. Internally administer Chansu Wan (Toad Venom Pill, 蟾酥丸) and Xiaoyao San (Dispersion of Toxin Decoction, 仙方活命饮) to dissipate the toxin. If there is constipation and a full pulse, administer Liangge San (Cooling the Diaphragm Powder, 凉膈散) to unblock the bowels and drain heat. After suppuration, use Tuoli Xiaodu San (Support the Interior and Detoxify Decoction, 托里消毒散); after rupture, use Bazhen Tang (Eight Treasures Decoction, 八珍汤) or Shiquan Dabu Tang (Complete Great Tonifying Decoction, 十全大补汤) and other tonics to close the wound.
The Shanzhong abscess (Shanzhong ju) arises above the heart pit, between the two breasts, belonging to the Shanzhong acupoint (CV17) of the Ren Mai (Conception Vessel). Shanzhong is the Sea of Qi, where Qi resides and distributes Yin and Yang. If the Yin and Yang of the Zang-Fu organs are disharmonious, or if the Seven Emotions are imbalanced, this toxic condition may arise. Initially, one may also administer Chansu Wan and Xiaoyao San. If there is swelling, hardness, fever, vomiting, constipation, irritability, desire for cold drinks, dry tongue, bitter taste, and deep, full, and forceful pulses throughout all positions, Neishu Huanglian Tang (Internal Draining Coptis Decoction, 内疏黄连汤) is suitable to eliminate the pathogen internally, preventing the pathogen from transmitting to the Heart, which would be auspicious. Other treatments follow the methods described above.
Gan ju (Sweet Abscess) arises at the elevated fleshy area above the breast, below the Zhongfu acupoint (LU1) of the Lung Meridian. Regardless of whether it is on the left or right, it is caused by Qi stagnation due to worry and overthinking. The treatment method is the same as above.
When a person suffers from chronic cough leading to lung injury, the skin becomes yellow and emaciated, hair is brittle, complexion is sallow, voice is hoarse, there is alternating chills and fever, spontaneous sweating and night sweats, asthma preventing lying flat, frequent urination without thirst, turbid saliva and phlegm foam in the mouth but no pus, and the Cun Kou (Radial Pulse) is rapid, empty, and choppy, this is Fei Wei (Lung Withering). When a person experiences pain in the chest and diaphragm, dry throat and mouth with thirst,急促 asthma preventing rest, incessant cough, severe pain when expectorating phlegm, worsened shortness of breath upon pressure, unbearable pain, slight swelling of the four limbs, a fishy odor from the throat, expectoration of pus and blood, rough skin on the chest resembling scales, slight elevation of the flesh, ability to sleep on the right side but inability to sleep on the left (as left-side sleeping causes急促 asthma and discomfort), and a rapid and forceful pulse, this is Fei Yong (Lung Carbuncle). "Wei" means withering, like plants that wither and lose vitality, caused by the loss of Jin-Ye (Body Fluids) and exhaustion of Qi. "Yong" means obstruction, caused by the stagnation and reversal of Lung Qi accumulating over time. The Lung is the canopy of the five Zang organs, located in the chest, governing Qi, and manifesting in the skin and hair. Any labor or injury to Blood and Qi, deficiency of Cou-Li (Intercellular spaces/Skin pores) allowing Wind pathogen to invade, affecting the Lung internally, leads to sweating, aversion to wind, cough, shortness of breath, nasal congestion, neck stiffness, chest and hypochondriac fullness. If prolonged without recovery, it becomes Fei Wei. Alternatively, excessive sweating or purgation causing severe loss of Body Fluids can also lead to this. If Wind pathogen affects the Wei (Defensive) level, hindering exhalation, and Heat forces the Ying (Nutritive) level, hindering inhalation, Wind damages the skin and hair, Heat damages the Blood vessels. Wind and Heat contend, causing Qi and Blood to stagnate and accumulate in the Lung, eventually transforming into Fei Yong. Furthermore, excess sexual activity depleting Kidney Water, causing Deficient Fire to flare up, or consumption of rich wine, roasted/spicy foods steaming the Lung, can all lead to Yong. However, Wei is characterized by Righteous Qi deficiency, while Yong is characterized by Pathogenic Qi excess. For Righteous Qi deficiency, treatment should be gradual; for Pathogenic Qi excess, treatment should be swift. Deficiency requires tonification with clearing elements; excess requires tonification with draining elements. For treating Fei Wei, Qingzao Jiufei Tang (Clear Dryness and Rescue the Lung Decoction, 清燥救肺汤) is suitable. For treating Fei Yong, if not yet ruptured, Tingli Dazao Xiefei Tang (Descurainia Seed and Jujube Decoction to Drain the Lung, 葶苈大枣泻肺汤) or Qianjin Weijing Tang (Thousand Gold Reed Rhizome Decoction, 千金苇茎汤) is suitable; if already ruptured, Neibu Huangqi Tang (Internal Tonification Astragalus Decoction, 内补黄芪汤) is suitable.
