夫肺主气，候于皮毛。气虚腠理受寒，寒客经络，则血痞涩，热气乘之，则结成痈也。
肺气虚寒，寒复乘肺，肺感于寒则成咳嗽，故发痈而嗽也。
此由寒气客于经络，折于气血，壅结不通，结成痈肿。发痈而利者，由内热而引饮，取
冷太过，冷入肠胃，故令下利也。下利不止，则变呕哕。所以然者，脾与胃合，俱象土；脾
候身之肌肉，胃为水谷之海。脾虚，肌肉受邪；胃虚，则变下利。下利不止，则变呕哕也。
此由寒客于经络，寒搏于血，血涩不通，壅结成痈。脏热不泄，热入大小肠，故大小便
此由体虚受寒，寒客于经络，血脉痞涩，热气蕴积，结聚成痈。结热不散，热气内迫于
心，故心虚热，则惊不定也。
此由寒客于经络，则血涩不通，与寒相搏，则结成痈肿。热气乘之，则血化为脓。脓溃
之后，热肿乃散，余寒不尽，肌肉未生，故有恶液澳汁，清而色黄不绝也。
此由寒气客于经络，血涩不通，壅结成痈。凡痈脓溃之后，须着排脓药，令热毒脓血俱
散尽。若有恶肉，亦敷药食之，则好肉得生，真气得复。若脓血未尽，犹挟余毒，疮口便合
，当时虽瘥，而后终更发。
此由寒气客于经络，血涩不通，壅结成痈。发痈之后，热毒未尽，重有风冷乘之，冷搏
于肿，蕴结不消，故经久一瘥一发，久则变成 也。
肺主司气，其生理状态反映于皮毛。若肺气虚弱，腠理（皮肤纹理及汗孔）易受寒邪侵袭，寒邪客留于经络之中，导致血液运行阻滞涩滞；此时热气乘虚而入，便会凝结形成痈肿。
肺气既虚又感寒邪，寒邪再次侵犯肺部，肺受寒邪则引发咳嗽，因此会出现发痈并伴有咳嗽的症状。
这种情况是由于寒气客留于经络，阻碍气血运行，致使气血壅结不通，从而结成痈肿。若发痈的同时伴有腹泻，是因为体内有热而引动饮水，且摄取生冷食物过多，冷气进入肠胃，从而导致下利（腹泻）。如果下利不止，就会转变为呕吐或呃逆。之所以如此，是因为脾与胃相表里，二者在五行中均对应土；脾主管身体的肌肉，胃是水谷之海。若脾气虚弱，肌肉易受邪气侵袭；若胃气虚弱，则会导致下利。若下利不止，就会进一步转变为呕吐或呃逆。
这种情况是由于寒邪客留于经络，寒邪与血液相互搏结，导致血液涩滞不通，壅结而成痈肿。脏腑内有热而不能宣泄，热气侵入大肠和小肠，因此出现大小便异常。（注：原文此处似有缺漏，依文意补全逻辑）
这种情况是由于体质虚弱感受寒邪，寒邪客留于经络，血脉阻滞涩滞，热气蕴积其中，聚结而成痈肿。若郁结的热气不能消散，热气向内逼迫心脏，导致心气虚弱而生热，就会出现心神不宁、惊恐不安的症状。
这种情况是由于寒邪客留于经络，导致血液涩滞不通，与寒邪相互搏结，从而结成痈肿。热气乘势而入，将血液化为脓液。脓液溃破之后，热肿得以消散，但残余的寒邪未尽，肌肉未能再生，因此会有恶臭的液体流出，质地清稀且颜色发黄，淋漓不尽。
这种情况是由于寒邪客留于经络，血液涩滞不通，壅结而成痈肿。凡是痈脓溃破之后，必须使用排脓药物，使热毒和脓血全部消散干净。若有坏死的腐肉，也应敷药使其脱落被吸收，这样好肉才能生长，真气才能恢复。如果脓血未排尽，仍挟带余毒，疮口便过早闭合，当时虽然看似痊愈，但日后终究会复发。
这种情况是由于寒邪客留于经络，血液涩滞不通，壅结而成痈肿。发痈之后，热毒尚未清除，又再次遭受风冷侵袭，冷邪搏结于肿胀之处，蕴结不散，因此病情经久不愈，时好时坏，日久则会转变为瘘管（注：原文“变成 也”中间缺字，据《诸病源候论》语境及前文“久痈”标题，通常指变为瘘或漏）。
The Lung governs Qi, and its condition is reflected in the skin and hair (mao pi). If Lung Qi is deficient, the interstices (cou li) are susceptible to Cold invasion. When Cold lodges in the meridians, blood circulation becomes obstructed and sluggish; if Heat takes advantage of this deficiency, it condenses to form an abscess (yong).
When Lung Qi is deficient and cold, Cold re-invades the Lung. The Lung, affected by Cold, gives rise to coughing; thus, an abscess may erupt accompanied by cough.
This condition arises because Cold lodges in the meridians, impeding the flow of Qi and Blood, causing stagnation and knotting that forms a swelling or abscess. If an abscess erupts accompanied by diarrhea, it is due to internal Heat prompting excessive drinking, particularly of cold substances. This cold enters the intestines and stomach, causing lower purging (xia li). If the diarrhea persists, it transforms into vomiting or hiccups. This occurs because the Spleen and Stomach are exterior-interiorly related and both correspond to Earth in the Five Phases; the Spleen governs the muscles of the body, while the Stomach is the Sea of Water and Grain. If Spleen Qi is deficient, the muscles are vulnerable to pathogenic factors; if Stomach Qi is deficient, it leads to diarrhea. Persistent diarrhea then transforms into vomiting or hiccups.
This condition arises because Cold lodges in the meridians and contends with Blood, causing Blood to become sluggish and obstructed, leading to stagnation and the formation of an abscess. Internal organ Heat fails to dissipate, and Heat enters the Large Intestine and Small Intestine, resulting in abnormalities in urination and defecation.
This condition arises because constitutional deficiency allows Cold invasion, with Cold lodging in the meridians, causing blood vessels to become obstructed and sluggish. Heat accumulates within, condensing to form an abscess. If the condensed Heat does not disperse, it presses inward upon the Heart, causing Heart Qi deficiency and internal Heat, which leads to palpitations and restlessness.
This condition arises because Cold lodges in the meridians, causing Blood to become sluggish and obstructed, contending with Cold to form a swelling or abscess. Heat takes advantage of this, transforming Blood into pus. After the pus ruptures, the heat-induced swelling disperses, but residual Cold remains, and the muscles fail to regenerate. Consequently, foul-smelling discharge flows continuously, clear in texture and yellow in color.
This condition arises because Cold lodges in the meridians, causing Blood to become sluggish and obstructed, leading to stagnation and the formation of an abscess. After any abscess or pus has ruptured, one must administer drugs that promote pus drainage to ensure all heat-toxic pus and blood are completely dispersed. If there is necrotic flesh, medicaments should be applied to dissolve it, allowing healthy tissue to grow and True Qi to recover. If pus and blood are not fully discharged, remaining toxins persist, and the wound closes prematurely. Although it may appear healed initially, it will ultimately recur later.
This condition arises because Cold lodges in the meridians, causing Blood to become sluggish and obstructed, leading to stagnation and the formation of an abscess. After the abscess erupts, if heat-toxins are not fully cleared, Wind-Cold may invade again. Cold contends with the swelling, causing stagnation that fails to resolve. Thus, the condition persists for a long time, alternating between remission and exacerbation, and over time may transform into a fistula (lou).
