这是由于寒气侵入经络，阻碍气血运行，导致血液涩滞不通，从而凝结形成痈。痈发于背部时，因五脏热盛且阴虚燥热，所以会出现口渴的症状。如果此时饮用冷冻饮料进入肠胃，就会转变为腹泻。
肺主司气，其外候反映在皮毛上。若肺气虚弱，腠理（皮肤纹理及汗孔）受寒邪侵袭，寒邪客居于经络，导致血行痞塞涩滞，热气乘虚而入，便会凝结成痈。若肺气本已虚弱，寒邪再次侵犯肺部，肺感受寒邪后就会引发咳嗽，因此患痈时会兼有咳嗽症状。
这是因为寒邪客居经络，导致血气痞塞涩滞，进而产生热邪，热邪蕴结而形成痈。若气机壅滞在脏腑，热邪深入肠胃，就会导致大便异常（此处原文似有缺漏，依文意推测为泄利或便秘等症，但严格按“不遗漏”原则，仅翻译可见部分：故令大便不……）。
这是由于寒气客居经络，阻碍气血，使血液涩滞不通，从而凝结成痈发背。脓液溃破之后，若外部风邪与疮口相搏结，变化生成恶肉（坏死的腐肉），堵塞疮口，则毒瓦斯会向内侵扰，必须敷药以消除这些恶肉。
疽发于背部，多发生在各脏腑的俞穴处。五脏功能不调就会发生疽，五脏的俞穴都在背部，其气血经络遍布全身。若脏腑功能不调，腠理空虚，经脉被寒邪所客，寒邪折损血液，导致血液壅滞不通，因而凝结成疽，并发作于脏腑的俞穴处。热气施注于血液，会导致血肉败坏腐烂化为脓液。疽初起时的形态，皮肤坚硬如同牛颈部的皮一样。疽比痈病情更重，发病者大多死亡。若刺破疽发部位，起始于肺俞或肝俞，若不进行泻法治疗，二十日后会死亡。在第八天时可以施行针刺。若患处发红，其上生的肉粒像花椒子一样，则是死证，无法医治。人在十九岁、二十五岁、三十三岁、四十九岁、五十七岁、六十岁、七十三岁、八十一岁、九十七岁时，神气皆位于背部，不可见血，若见血则会死亡。
蜂疽发于背部，起始于心俞或肩膊部，二十天内若不进行泻法治疗就会死亡。在第八天时可以施行针刺。若患处颜色赤黑，脓液中见到青色，则是死证，无法医治。人在六岁、十八岁、二十四岁、四十岁、五十六岁、六十七岁、七十二岁、九十八岁时，神气皆位于肩膊部，不可见血，若见血则会死亡。
This condition arises from cold pathogenic factors invading the meridians and collaterals, obstructing the flow of Qi and blood. The blood becomes stagnant and unsmooth, eventually condensing to form a carbuncle (Yong). When a carbuncle manifests on the back, it is due to excessive heat in the five Zang organs combined with deficiency and dryness, leading to thirst. If frozen beverages are ingested into the stomach and intestines, this may transform into diarrhea.
The Lung governs Qi and its external manifestation is on the skin and hair. If Lung Qi is deficient, the interstices (Cou Li) are susceptible to cold invasion. Cold pathogens lodging in the meridians cause blood stasis and stagnation; when heat pathogens take advantage of this, they condense to form a carbuncle. If Lung Qi is already deficient and cold pathogens re-invade the Lung, causing the Lung to contract cold, cough will ensue. Therefore, a carbuncle may occur accompanied by coughing.
This results from cold pathogens lodging in the meridians, causing Qi and blood to become obstructed and stagnant, which generates heat. This heat accumulates and condenses to form a carbuncle. If Qi becomes congested within the Zang-Fu organs and heat enters the stomach and intestines, it causes abnormalities in bowel movements (text incomplete: "thus causing stool not...").
This occurs because cold pathogens lodge in the meridians, obstructing Qi and blood, making blood stagnant and unsmooth, thereby condensing into a carbuncle on the back. After the pus ruptures, if external wind pathogens contend with the wound, malignant flesh (necrotic tissue) may develop. If this blocks the sore, toxic vapors will invade internally; medicinal applications must be used to eliminate this malignant flesh.
Carbuncles on the back often arise at the Shu points of various Zang organs. Dysfunction of the five Zang organs leads to the development of a carbuncle (Ju). The Shu points of the five Zang organs are all located on the back, where Qi, blood, and meridians circulate throughout the body. If Zang-Fu dysfunction occurs and the interstices are deficient, meridians are invaded by cold. Cold damages the blood, causing stagnation and obstruction, thus condensing into a Ju that manifests at the Zang Shu points. Heat applied to the blood causes flesh and blood to rot and decay into pus. The initial appearance of a Ju features skin that is hard like the hide of an ox's neck. A Ju is more severe than a Carbuncle, and those who develop it often die. If needling is performed for a Ju starting at Feishu (BL13) or Ganshu (BL18), and purging methods are not employed, death will occur in twenty days. Needling can be performed on the eighth day. If the area is red and the flesh resembles peppercorns, it is an incurable fatal condition. At ages nineteen, twenty-five, thirty-three, forty-nine, fifty-seven, sixty, seventy-three, eighty-one, and ninety-seven, the Spirit resides in the back; bleeding should be avoided, as bleeding leads to death.
Bee-like Ju on the back starts at Xinshu (BL15) or the shoulder/arm region. If purging is not performed within twenty days, death will ensue. Needling can be performed on the eighth day. If the color is dark red-black and green appears in the pus, it is an incurable fatal condition. At ages six, eighteen, twenty-four, forty, fifty-six, sixty-seven, seventy-two, and ninety-eight, the Spirit resides in the shoulder/arm region; bleeding should be avoided, as bleeding leads to death.
