此由寒气客于经络，折于气血，血涩不通，乃成疽发。疽溃之后，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。除此者并为顺矣。此五种皆死候。
凡发痈疽，则热流入内，五脏焦燥，渴而引饮，兼多取冷，则肠胃受冷而变下利。利则
肠胃俱虚，而冷搏胃气，气逆则变呕。逆气不通，遇冷折之，则哕也。
缓疽者，由寒气客于经络，致荣卫凝涩，气血壅结所成。其寒盛者，则肿结痛深，而回
回无头尾，大者如拳，小者如桃李，冰冰与皮肉相亲着。热气少，其肿与肉相似，不甚赤，
积日不溃，久乃变紫黯色，皮肉俱烂，如牛领疮，渐至通体青黯，不作头，而穿溃脓出是也
。以其结肿积久，而肉腐坏迟，故名缓疽。亦名肉色疽也。缓疽急者，一年杀人；缓者，数
疽之状，肉生小黯点，小者如粟豆，大者如梅李，或赤或黑，乍青乍白，有实核
，燥痛应心。或着身体。其着手指者，似代指，人不别者，呼为代指。不急治，毒逐脉上，
入脏则杀人。南方人得此疾，皆截去指，恐其毒上攻脏故也。
又云∶十指端忽策策痛，入心不可忍。向明望之，晃晃黄赤，或黯黯青黑，是
疽。直截后节，十有一冀。
又云∶风胗痛不可忍者， 疽。发五脏俞，节解相应通洞， 疽也。诸是
疽皆死。又齿间臭热，血出不止， 疽也，七日死。治所不瘥，以灰掩覆其血，不尔
又云∶诸是 疽皆死，唯痛取利，十有一活耳。此皆毒瓦斯客于经络，气血痞涩，毒
这是由于寒气侵入经络，阻碍气血运行，导致血液涩滞不通，从而形成疽病。疽病溃烂之后，有预后不良（逆）和预后良好（顺）的区别。如果患者眼白部分呈现青黑色且瞳孔缩小，这是第一种逆证；服药后发生呕吐，这是第二种逆证；腹部疼痛且极度口渴，这是第三种逆证；手臂和颈部活动不便，这是第四种逆证；声音嘶哑、面色枯槁无华，这是第五种逆证。除了这五种情况外，其余都属于顺证。这五种情况都是死亡的征兆。
凡是发生痈疽，热邪就会内传入里，导致五脏焦躁干燥，出现口渴想喝水的症状。如果此时又大量饮用冷饮，就会导致肠胃受寒而变成泄泻。腹泻会导致肠胃虚弱，寒气与胃气相搏结，气机上逆则变为呕吐。逆气不通畅，再遇到寒气遏制，就会产生呃逆（哕）。
缓疽，是由于寒气侵入经络，导致营卫之气凝滞涩阻，气血壅结郁滞所形成的。寒气盛行的，肿胀结聚且疼痛深在，没有明显的头尾界限，大的像拳头，小的像桃李，冰冷地与皮肉粘连在一起。热气较少的，肿胀与肌肉相似，不太发红，经过多日不溃破，时间久了变成紫暗色，皮肉全部腐烂，像牛颈部的疮一样，逐渐发展到全身青暗，没有脓头，最终穿破溃烂流出脓液。因为结肿积聚日久，肉质腐烂缓慢，所以称为缓疽。也称为肉色疽。病情急的缓疽，一年内可致人死亡；病情缓的，数年……
疽病的症状，皮肤上生出细小的暗色斑点，小的像粟米豆子，大的像梅子李子，颜色或红或黑，时而发青时而发白，有坚实的硬结，干燥疼痛并牵连心脏部位。或者发生在身体其他部位。如果发生在手指上，类似代指病，人们分辨不清时，就称之为代指。如果不及时救治，毒邪顺着经脉上行，进入脏腑就会致死。南方人得了这种病，都会截去手指，是担心毒邪上攻脏腑的缘故。
又说：十个手指尖端突然感到刺痛，痛入心脏难以忍受。对着光亮观察，色泽晃晃黄赤，或暗暗青黑，这就是疽。应当直接截除远端指节，共有十一处可能涉及。
又说：风疹疼痛难以忍受的，是疽。发于五脏俞穴，关节解离相应通畅洞开，也是疽。所有这类疽病都是死证。另外，齿间有臭热感，出血不止，也是疽病，七日内死亡。治疗无效，用灰烬覆盖止血，否则……
This condition arises from cold pathogenic factors invading the meridians and collaterals, obstructing the flow of Qi and Blood. The blood becomes stagnant and unobstructed, leading to the formation of a Ju (a deep-seated, suppurative lesion). After a Ju ulcerates, there are signs indicating a favorable prognosis (Shun) and an unfavorable prognosis (Ni). If the sclera appears blue-black with constricted pupils, this is the first sign of Ni; vomiting after taking medicine is the second sign of Ni; abdominal pain accompanied by extreme thirst is the third sign of Ni; inability to move the arms and neck is the fourth sign of Ni; hoarseness of voice and loss of luster in complexion is the fifth sign of Ni. Apart from these five conditions, all others are considered Shun. These five conditions are all indicators of death.
Whenever a Yong (superficial abscess) or Ju erupts, heat pathogens flow inward, causing the Five Zang Organs to become scorched and dry, leading to thirst and a desire to drink. If one concurrently consumes large amounts of cold beverages, the intestines and stomach suffer from cold, resulting in diarrhea. Diarrhea weakens the intestines and stomach; cold combats Stomach Qi, causing Qi rebellion which transforms into vomiting. When rebellious Qi fails to circulate smoothly and encounters cold obstruction, it results in hiccups (Yue).
Huan Ju (Slow Ju) is formed due to cold pathogens invading the meridians and collaterals, causing stagnation and涩ness (sluggishness) of Ying (Nutritive) and Wei (Defensive) Qi, and congestion and knotting of Qi and Blood. In cases of severe cold, swelling knots and pain are deep, without distinct heads or tails; large ones resemble fists, small ones resemble peaches or plums, feeling icy and adhering closely to the skin and flesh. In cases with less heat, the swelling resembles muscle tissue, is not very red, does not ulcerate for many days, and eventually turns purple-dark. The skin and flesh rot entirely, resembling ulcers on a cow's neck, gradually spreading until the whole body appears cyanotic and dark, without forming a head, finally penetrating and discharging pus. Because the nodular swelling persists for a long time and tissue necrosis is slow, it is named Huan Ju. It is also called Rou Se Ju (Flesh-Color Ju). Acute cases of Huan Ju can cause death within a year; chronic cases may take several years...
The manifestations of Ju include small dark spots growing on the flesh, small as millet seeds or beans, large as plums or peaches. They may be red or black, alternating between cyan and white, possessing solid nodules, causing dryness, pain, and discomfort radiating to the heart. They may appear on various parts of the body. Those appearing on the fingers resemble Dai Zhi (paronychia); when people cannot distinguish them, they are called Dai Zhi. If not treated promptly, toxins travel upward along the meridians and enter the Zang Organs, causing death. People in the southern regions who contract this disease often amputate the affected finger, fearing that the toxin will attack the Zang Organs.
It is also stated: Sudden stabbing pain at the tips of the ten fingers, unbearable as if entering the heart, indicates Ju. Looking towards the light, the color appears bright yellow-red or dull cyan-black. One should directly amputate the distal phalanx; there are eleven such sites potentially involved.
It is also stated: Wind rash (Feng Zhen) with unbearable pain indicates Ju. Eruption at the Shu points of the Five Zang Organs, with joint separation and corresponding open channels, also indicates Ju. All such Ju conditions are fatal. Additionally, foul heat sensation in the gums with continuous bleeding indicates Ju, leading to death within seven days. If treatment fails to heal, covering the blood with ash stops it; otherwise...
It is also stated: All such Ju conditions are fatal; only those with mild pain have a one-in-ten chance of survival. These are all caused by toxic pathogens residing in the meridians and collaterals, causing Qi and Blood to become blocked and sluggish, with toxins...
