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
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...
