此由寒气搏于肌肉，折于血气，结聚乃成痈。凡痈经久，不复可消者，若按之都牢坚者
，未有脓也；按之半坚半软者，有脓也。又，以手掩肿上，不热者，为无脓；若热甚者，为
有脓。凡觉有脓，宜急破之；不尔，侵食筋骨也。
此由寒气客于肌肉，折于血气，结聚乃成痈。凡痈破溃之后，有逆有顺。其眼白睛青黑
，而眼小者，一逆也；内药而呕者，二逆也；腹痛、渴甚者，三逆也；膊项中不便者，
四逆也；音嘶色脱者，五逆也。除此者并为顺也。此五种皆死候。
凡发痈疽，则热流入内，五脏焦燥者，渴而引饮，兼多取冷，则肠胃受冷而变下利。利
则肠胃俱虚，而冷搏于胃，气逆则变呕逆；气不通，遇冷折之，则变哕也。
石痈者，亦是寒气客于肌肉，折于血气，结聚所成。其肿结确实，至牢有根，核皮相亲
，不甚热，微痛，热时自歇。此寒多热少，坚如石，故谓之石痈也。久久热气乘之，乃有脓也。
附骨痈，亦由体痈热而当风取凉，风冷入于肌肉，与热气相搏，伏结近骨成痈。其状无
头，但肿痛而阔，其皮薄泽，谓之附骨痈也。
此是寒客于经络，使血气痞涩，乃结肿成痈。热气壅结，则血化为脓。脓溃痈瘥之后，
余热未尽，而血气已虚，其人吸吸苦热， 虚乏，故谓之虚热。
痈由寒搏于血，血涩不通，而热归之，壅结所成。热气不得宣泄，内熏五脏，故烦躁而
凡痈肿热渴引饮，冷气入肠胃，即变下痢，并变呕哕。所以然者，本内虚热，气逆，故
呕；呕而气逆，外冷乘之，气不通，故哕也。
这是由于寒气搏结于肌肉，阻碍血气运行，气血凝结聚积而形成的痈肿。凡是痈肿经久不愈、无法消散的，如果按压时感觉整体坚硬牢固的，说明还没有化脓；如果按压时感觉一半坚硬一半柔软的，说明已经有脓了。另外，用手覆盖在肿胀处，如果不发热的，说明没有脓；如果发热严重的，说明有脓。凡是感觉到已经化脓，应当立即切开排脓；否则，脓毒会侵蚀筋骨。
这是由于寒气客居于肌肉，阻碍血气运行，气血凝结聚积而形成痈肿。凡是痈肿破溃之后，病情有顺证和逆证之分。患者眼白部分呈现青黑色，且眼睛变小，这是一逆；服药后出现呕吐，这是二逆；腹痛且口渴严重，这是三逆；手臂和颈部活动不便，这是四逆；声音嘶哑、面色枯槁无华，这是五逆。除了这五种情况外，其余都属于顺证。这五种情况都是死证的征候。
凡是发生痈疽，热气就会内传入里，导致五脏焦躁干燥，患者口渴想喝水，如果此时又过多地饮用冷饮，就会导致肠胃受寒而发生腹泻。腹泻会导致肠胃俱虚，寒气搏结于胃，气机上逆则变为呕吐；气机不通，再遇寒气遏制，就会变为呃逆（打嗝）。
石痈，也是寒气客居于肌肉，阻碍血气运行，气血凝结聚积所形成。其肿块坚实牢固，根基深固，皮肤与肿块紧密相连，不太发热，仅有轻微疼痛，发热时断时续。这是因为寒多热少，质地坚硬如石头，所以称为石痈。时间久了，热气乘虚而入，才会化脓。
附骨痈，也是因为身体已有痈肿发热时，贪凉当风，风冷之气侵入肌肉，与体内的热气相互搏结，潜伏凝结在近骨之处而形成痈肿。其症状是没有明显的脓头，只是肿痛且范围较宽，皮肤薄而光亮，称为附骨痈。
这是由于寒气客居于经络，使血气阻滞涩滞，从而凝结成肿形成痈肿。热气壅结，血液化为脓液。脓液溃破、痈肿痊愈之后，余热尚未清除，而血气已经虚弱，患者感到持续不断的烦热，身体虚弱乏力，所以称为虚热。
痈是由于寒气搏结于血分，导致血液涩滞不通，热气随之归聚，因壅结而成。热气不能宣泄，向内熏蒸五脏，所以出现烦躁不安。凡是痈肿伴有热渴引饮，冷气进入肠胃，就会转变为下痢，并可能转变为呕吐和呃逆。之所以这样，是因为原本体内就有虚热，气机上逆，所以呕吐；呕吐后气机更加上逆，外部寒气乘虚而入，气机不通，所以呃逆。
This arises from cold pathogenic factors clashing with the muscles, obstructing the flow of blood and qi (vital energy), leading to coagulation and accumulation, thereby forming a carbuncle (a deep-seated skin infection). For any carbuncle that has persisted for a long time and cannot be resolved, if palpation reveals it is uniformly hard and firm, there is no pus; if palpation reveals it is half-hard and half-soft, there is pus. Furthermore, placing a hand over the swelling: if it is not hot, there is no pus; if it is severely hot, there is pus. Whenever pus is detected, it should be incised and drained immediately; otherwise, the toxic pus will erode the sinews and bones.
This arises from cold pathogenic factors lodging in the muscles, obstructing the flow of blood and qi, leading to coagulation and accumulation, thereby forming a carbuncle. After a carbuncle ruptures and ulcerates, the prognosis can be either favorable (Shun) or unfavorable (Ni). The patient having white sclerae turning blue-black and eyes appearing small constitutes one unfavorable sign; vomiting after taking medicine constitutes the second unfavorable sign; abdominal pain and severe thirst constitute the third unfavorable sign; inability to move the arms and neck constitutes the fourth unfavorable sign; hoarseness and loss of complexion/luster constitutes the fifth unfavorable sign. Apart from these five, all other conditions are considered favorable. These five signs indicate a fatal outcome.
Whenever a carbuncle or furuncle erupts, heat pathogens enter the interior, causing the Zang organs (internal organs) to become scorched and dry. The patient feels thirsty and desires to drink. If they consume excessive cold beverages, the intestines and stomach suffer from cold, leading to diarrhea. Diarrhea causes deficiency in both the intestines and stomach. Cold clashes with the Stomach, causing Qi rebellion, which transforms into vomiting; if Qi circulation is blocked and further constrained by cold, it transforms into hiccups (inverted Qi).
Shi Yong (Stone Carbuncle) is also formed by cold pathogenic factors lodging in the muscles, obstructing blood and qi flow, and resulting from coagulation and accumulation. The swelling is solid and firm, deeply rooted, with the skin adhering closely to the mass. It is not very hot, presents with slight pain, and fever comes and goes. Because cold predominates over heat and the hardness resembles stone, it is called Stone Carbuncle. After a long period, heat pathogens may invade, eventually leading to pus formation.
Fu Gu Yong (Bone-Adhering Carbuncle) occurs when a person, already suffering from heat in a systemic carbuncle, seeks cooling by exposing themselves to wind and cold. Wind-cold enters the muscles and clashes with internal heat, lying dormant and accumulating near the bone to form a carbuncle. Its presentation lacks a distinct head, presenting only with widespread swelling and pain, and thin, glossy skin. This is called Bone-Adhering Carbuncle.
This results from cold pathogens lodging in the meridians, causing stagnation and涩ness (sluggishness) of blood and qi, leading to coagulation, swelling, and carbuncle formation. Heat pathogens accumulate and congeal, transforming blood into pus. After the pus drains and the carbuncle heals, residual heat remains while blood and qi are deficient. The patient suffers from continuous low-grade fever and general weakness and fatigue, hence termed Deficient Heat.
Carbuncles arise from cold pathogens clashing with the blood, causing blood sluggishness and obstruction, followed by the gathering of heat, resulting from accumulation and congestion. Heat fails to vent outward and steams inwardly affecting the Zang organs, causing restlessness and irritability. In cases of carbuncles with heat-induced thirst and drinking, if cold pathogens enter the intestines and stomach, they transform into dysentery, and may also transform into vomiting and hiccups. The reason for this is that internally there is originally deficient heat causing Qi rebellion, leading to vomiting; after vomiting, Qi rebels further, and external cold exploits this vulnerability, blocking Qi circulation, thus causing hiccups.
