大凡气血不调，经络不通，复感六气七情，故毒瓦斯乘风热而走是也。此证因风
盛而生热之证，热极气盛，气因热之极而走于四散，急宜疏风定热，则风自息。若
元气盛，初发者，速以艾灸七壮，四围敷药，内服流气饮，无不愈者。若流注于腿脚者，死无疑矣。
《图经》古方疗恶疮痈肿，或连阴髀间疼痛，急挛牵入小腹，不可忍者，一宿则
杀人，用茴香苗叶捣取汁，一升，服之，日三四，用其滓以粘贴，冬月根亦可用。此
海外方，永嘉以来用之起死神效。（《准绳》）
王肯堂曰∶痈疽目斜视上，黑睛紧小，白睛青赤，此肝挟火邪也。（《准绳》）
蒋示吉曰∶宜六味地黄丸料，加山栀、麦冬、北五味子治之。（《说约》）
夫疮疡发痉，因气血亏损，外邪所抟，或内虚郁火所致。其证牙关紧闭，四肢劲
强，或腰背反张，肢体抽搐，其有汗而不
恶寒者，曰柔痉。风能散气，故有汗也，其无汗而恶寒者，曰刚痉。寒能涩血，故无
汗也。皆由亡血过多，筋无所养，故伤寒汗下过多，与溃疡产后多患之，乃败证也。
若大补气血，多有复生者。若作风治，速其危矣。
王肯堂曰∶四肢逆冷，乃胃气虚寒也。（《准绳》）
澄曰∶寒热之厥，辨在何处？盖寒厥四肢逆冷，过乎肘膝，指甲青，脉沉细无
力，有寒证见于外；若热极而厥者，火极似水，虽厥而指甲尚温，不似寒厥过乎肘
膝，脉来沉实，大而有力，以此为辨。寒厥疮必灰白下陷，热厥疮必紫暗干枯。
大凡气血不调和，经络不通畅，又感受六淫邪气和七情内伤，所以毒瓦斯乘着风热之气而流散走窜。这种病症是因为风邪偏盛而生热，热势极盛导致气机亢奋，气随着热势的极致而向四周流散，应当紧急疏风清热，那么风邪自然平息。如果患者元气充足，且是初发病症，迅速用艾灸灸七壮，在疮疡周围敷药，内服流气饮，没有不痊愈的。如果毒气流注到腿脚部位，则必定死亡无疑。
《图经》中的古方治疗恶疮痈肿，或者疼痛连及阴部和大腿之间，急迫拘挛牵引进入小腹，痛得无法忍受，一晚上就能致人死亡，用茴香的苗叶捣取汁液，服用一升，每天三四次，并用剩下的药渣粘贴患处，冬季也可以用根部。（出自《医学准绳六要》）
王肯堂说：痈疽患者出现目斜视向上，黑眼球紧缩变小，白眼球青赤色，这是肝脏夹杂火邪所致。（出自《医学准绳六要》）
蒋示吉说：适宜使用六味地黄丸的药料，加入山栀、麦冬、北五味子来治疗。（出自《医宗说约》）
疮疡发作痉挛，是因为气血亏损，外邪搏结，或者是内部虚弱郁火所致。其症状表现为牙关紧闭，四肢僵硬强直，或者腰背向后反张，肢体抽搐。如果有汗但不怕冷的，称为柔痉。风能耗散气机，所以会有汗出；如果没有汗且怕冷的，称为刚痉。寒性能使血液凝涩，所以无汗。这都是因为失血过多，筋脉失去滋养，所以在伤寒病中发汗或攻下过多，以及溃疡病患者和产后妇女多患此病，属于败坏危重的证候。如果大补气血，大多能复活。如果当作风邪来治疗，会加速其危险。
王肯堂说：四肢逆冷，是胃气虚寒所致。（出自《医学准绳六要》）
顾世澄说：寒厥和热厥的区别在哪里？寒厥导致的四肢逆冷，超过肘部和膝盖，指甲发青，脉象沉细无力，体表有寒证表现；如果是热极导致的厥逆，火极似水，虽然四肢厥冷但指甲尚且温暖，不像寒厥那样超过肘膝，脉象沉实、大而有力，以此作为辨别依据。寒厥的疮疡颜色必为灰白且下陷，热厥的疮疡颜色必为紫暗干枯。
Generally, when Qi and Blood are disordered and meridians are obstructed, compounded by the contraction of the Six Evils (Six Pathogenic Factors) and Seven Emotions, toxic vapors will follow wind-heat to scatter and flow. This syndrome arises from excessive Wind generating Heat; when Heat reaches its extreme and Qi becomes hyperactive, Qi scatters in all directions due to the extremity of Heat. It is urgent to dispel Wind and settle Heat, so that Wind will naturally subside. If the Original Qi is robust and it is an initial onset, moxibustion should be applied rapidly for seven moxa cones, medicine should be applied around the lesion, and Liuxi Yin (Flowing Qi Decoction) should be taken internally; there will be no case that does not heal. However, if the pathogen flows into the legs and feet, death is inevitable.
Ancient prescriptions in *Tu Jing* treat malignant sores and carbuncles, or pain extending to the groin and thigh region, with urgent spasms pulling into the lower abdomen, unbearable to endure, which can kill within one night. Use the seedlings and leaves of Fennel (*Foeniculi Vulgaris Fructus*, though here referring to foliage/roots contextually often implying *Anisi Stellati Fructus* but text says 'seedling/leaf', strictly translating as Fennel seedling/leaf juice), crush and extract the juice, take one sheng, three to four times a day. Apply the dregs topically. In winter, the root may also be used. This is a foreign prescription, effective in reviving the dying since the Yongjia era. (From *Zhunsheng*)
Wang Kentang stated: In carbuncles and ulcers, if the eyes deviate upward, the black pupil is tight and small, and the white sclera is blue-red, this indicates Liver Fire mixed with evil pathogens. (From *Zhunsheng*)
Jiang Shiji stated: It is suitable to treat with Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) formula, adding Gardenia (*Gardeniae Fructus*), Ophiopogon (*Ophiopogonis Radix*), and Schisandra (*Schisandrae Chinensis Fructus*). (From *Shuoyue*)
When sores and ulcers develop spasms, it is due to deficiency and loss of Qi and Blood, external pathogens clashing, or internal deficiency with stagnant fire. The symptoms include locked jaw, stiffness and rigidity of the four limbs, opisthotonos (arching of the back), and limb convulsions. Those who have sweat but do not fear cold are called "Rou Jing" (Yin Spasm). Wind disperses Qi, hence sweating occurs. Those who have no sweat and fear cold are called "Gang Jing" (Yang Spasm). Cold congeals Blood, hence no sweat occurs. All these result from excessive blood loss, leaving tendons without nourishment. Therefore, after excessive sweating or purgation in Cold Damage diseases, or in patients with chronic ulcers and postpartum women, this condition is frequently seen; it is a critical, deteriorating syndrome. If Qi and Blood are greatly tonified, many will recover. If treated as a Wind disorder, it will accelerate the danger.
Wang Kentang stated: Coldness and numbness of the four limbs indicate deficiency-cold of Stomach Qi. (From *Zhunsheng*)
Cheng stated: Where lies the distinction between Cold Jue and Heat Jue? In Cold Jue, the coldness of the four limbs extends beyond the elbows and knees, the fingernails turn cyan, the pulse is deep, fine, and weak, and cold signs appear on the exterior. In Heat Jue caused by extreme heat, Fire resembles Water; although there is Jue (cold extremities), the fingernails remain warm, unlike Cold Jue where coldness exceeds elbows and knees. The pulse in Heat Jue is deep, solid, large, and forceful, which serves as the basis for differentiation. In Cold Jue, the sore must be grayish-white and sunken; in Heat Jue, the sore must be purple-dark and dry/withered.
