脉紧而数，寒热俱发，必当下乃愈。脉急如弦者，邪入阳明，寒热。脾脉小甚为寒热。
《养生方》云∶已醉饱食，发寒热也。
夫人荣卫不调，致令阴阳痞塞，阳并于上则上热，阴并于下则下冷。上焦有热，或喉口

夫厥者，逆也。谓阴阳二气卒有衰绝，逆于常度。若阳气衰于下，则为寒厥；阴气衰于
下，则为热厥。
热厥之为热也，必起于足下者。阳气起于足五指之表，阴脉者，集于足下而聚于足心故

寒气并入阴分则表现为发冷，阳气并入阳分则表现为发热，阴阳二气的虚实失调，导致邪气交替发作，出现寒热往来的症状。
脉象紧而数，寒热同时发作，必须通过泻下法治疗才能痊愈。脉象急如弦状，说明邪气侵入阳明经，出现寒热症状。脾脉细小甚为严重，主寒热病。《养生方》说：酒醉饱食之后，会引发寒热症状。
人的营卫之气不调和，导致阴阳之气痞塞不通，阳气并聚于上部则上部发热，阴气并聚于下部则下部寒冷。上焦有热，可能导致咽喉口腔生疮，胸膈部烦闷胀满；下焦有寒，则会导致腹部胀满、肠鸣、绞痛以及泄痢。
所谓“厥”，就是逆乱的意思。指阴阳二气突然衰败断绝，违背了正常的规律。如果阳气在下部衰败，就形成寒厥；阴气在下部衰败，就形成热厥。
热厥之所以发热，必定从脚底开始。因为阳气起于足趾外侧，阴脉汇聚于脚底并聚集于脚心，所以阳气胜则脚底发热。热厥的发生，是因为饮酒入胃，导致络脉充盈而经脉空虚。脾脏负责为胃传输津液，阴气虚弱则阳气内陷，阳气内陷则胃气不和，胃气不和则精气枯竭，精气枯竭则不能滋养四肢。这种人必定是经常醉酒或饱食后行房事，气聚积在脾中未能疏散，酒气与谷气相搏结，热气产生于体内，进而遍布全身，内热导致小便赤黄。酒的性质盛大而猛烈，若肾气衰弱，阳气独盛，就会导致手脚发热。
寒厥的寒冷，必定从脚趾开始，向上蔓延至膝盖以下。阴气起于脚趾内侧，汇聚于膝下，聚集于膝上，所以阴气胜则从脚趾到膝盖以上感到寒冷。这种寒冷并非来自外部，而是全部源于内部虚寒。寒厥为何会这样？前阴部位是宗筋汇聚之处，也是太阴经和阳明经交汇的地方。春夏时节阳气多而阴气衰，秋冬时节阴气盛而阳气衰。这类人体质壮实，却在秋冬季节过度耗损精力（指房劳），导致下部之气上争而不能恢复，精气外溢下行，邪气随之上行，气机郁结在中焦，阳气衰败，不能渗透濡养经络，因此阳气日渐损耗，阴气独存，导致手足寒冷。
厥证，有的使人腹部胀满，有的使人突然昏倒不省人事，有的半天甚至一天后才苏醒，这是由于阴气盛于上部，导致下部之气重犯上部，邪气逆乱，逆乱则阳气紊乱，紊乱则神志昏迷。
太阳经发生厥逆，表现为脚跟疼痛、头部沉重，脚不能行走，突然跌倒。阳明经发生厥逆，则表现为癫狂欲奔走呼叫，腹部胀满不能卧睡，卧下则面红发热，胡言乱语。少阳经发生厥逆，则表现为突发耳聋、脸颊肿胀，胸部发热、胁肋疼痛，身体无法转动。太阴经发生厥逆，表现为腹部胀满，大便不通利，不想进食，进食则呕吐，无法安卧。少阴经发生厥逆，表现为舌干、小便赤黄，腹部胀满、心痛。厥阴经发生厥逆，表现为小腹部肿痛，腹胀，大小便不利，喜欢躺卧且屈曲膝盖，生殖器收缩肿胀，小腿内侧发热。关于汤药熨贴、针刺砭石的治疗，另有专门的正方，补养宣导的方法，现在附在后面。
《养生方·导引法》说：正身仰卧，舒展双脚，用鼻吸气，尽力做到极致，共呼吸七次，然后摇动双脚三十次停止。可以消除脚底寒冷和厥逆的症状。
When cold qi merges into the Yin aspect, chills manifest; when Yang qi merges into the Yang aspect, fever manifests. Due to the imbalance of deficiency and excess between Yin and Yang Qi (Vital Energy), pathogenic factors alternate in their activity, resulting in alternating chills and fever (alternating sensations of cold and heat).
A tight and rapid pulse indicates simultaneous onset of chills and fever, which must be treated with purgation (draining downward) to achieve recovery. A pulse tense as a string indicates pathogenic invasion of the Yangming Channel (Yangming Meridian), presenting with chills and fever. A significantly small Spleen pulse indicates chills and fever. The *Yangsheng Fang* states: consuming alcohol and food to satiety can induce chills and fever.
When the Ying (Nutritive) and Wei (Defensive) Qi are disordered, it causes stagnation and obstruction of Yin and Yang. When Yang Qi aggregates in the upper part, the upper body becomes hot; when Yin Qi aggregates in the lower part, the lower body becomes cold. Heat in the Upper Jiao (Upper Burner) may cause sores in the throat and mouth, and irritability and fullness in the chest and diaphragm; cold in the Lower Jiao (Lower Burner) leads to abdominal distension, borborygmus (intestinal rumbling), colic, diarrhea, and dysentery.
"Jue" (Reversal/Colliculus) refers to reversal or counterflow. It signifies that Yin and Yang Qi suddenly decline or sever, deviating from normal physiological limits. If Yang Qi declines in the lower part, it forms Cold Jue (Cold Reversal); if Yin Qi declines in the lower part, it forms Hot Jue (Hot Reversal).
The heat in Hot Jue invariably begins at the soles of the feet. This is because Yang Qi originates on the lateral side of the five toes, while Yin meridians converge at the sole and gather at the center of the foot. Thus, when Yang Qi prevails, the soles become hot. In Hot Jue, wine enters the Stomach, causing the Luo (Connecting) vessels to be full while the Jing (Main) vessels are empty. The Spleen governs transporting fluids for the Stomach. When Yin Qi is deficient, Yang Qi sinks inward; when Yang Qi sinks inward, Stomach Qi becomes disharmonious; when Stomach Qi is disharmonious, Essence-Qi (Jing-Qi) is exhausted; when Essence-Qi is exhausted, it fails to nourish the four limbs. Such individuals likely engage in sexual intercourse after frequent drunkenness or overeating. Qi gathers in the Spleen without dispersing; wine Qi and Grain Qi combine, generating internal heat that spreads throughout the body. Internal heat causes dark urine. Wine Qi is potent and fierce; if Kidney Qi is weak, Yang Qi alone prevails, causing heat in the hands and feet.
The cold in Cold Jue invariably starts at the toes and extends upward below the knees. Yin Qi originates from the medial side of the five toes, converges below the knees, and gathers above the knees. Thus, when Yin Qi prevails, coldness extends from the toes to above the knees. This cold does not come from outside but arises entirely from internal cold. Why does this happen? The anterior yin is the gathering place of the Zong Jin (Tendon Sheath/Major Tendons) and the convergence of the Taiyin and Yangming channels. In spring and summer, Yang Qi is abundant and Yin Qi declines; in autumn and winter, Yin Qi is abundant and Yang Qi declines. Individuals with robust constitutions who deplete their vitality during autumn and winter (e.g., through excessive sexual activity) experience contention of lower Qi rising upward, failing to recover. Essence-Qi leaks downward, and pathogenic factors follow upward. Qi becomes stagnant in the middle, Yang Qi declines, and fails to permeate and nourish the collaterals. Consequently, Yang Qi diminishes daily, leaving Yin Qi alone, resulting in cold hands and feet.
Jue syndrome may cause abdominal fullness, sudden loss of consciousness, or unconsciousness lasting half a day to a day before recovery. This occurs because Yin Qi is excessive in the upper part, causing lower Qi to press upward, leading to rebellious pathogenic Qi. Rebellion disrupts Yang Qi, and disruption leads to loss of consciousness.
Taiyang Jue presents with pain at the heels, heaviness of the head, inability to walk, and sudden collapse. Yangming Jue presents with manic epilepsy, desire to run and shout, abdominal fullness, inability to lie down, and upon lying down, facial redness, heat, visual hallucinations, and incoherent speech. Shaoyang Jue presents with sudden deafness, swollen cheeks, chest heat, hypochondriac pain, and inability to move. Taiyin Jue presents with abdominal distension, difficulty in defecation, anorexia, vomiting after eating, and insomnia. Shaoyin Jue presents with dry tongue, dark urine, abdominal fullness, and heart pain. Jueyin Jue presents with swelling and pain in the lower abdomen, abdominal distension, difficulty in urination and defecation, preference for lying down with knees flexed, contraction and swelling of the genitals, and heat in the medial aspect of the shins. Treatments involving decoctions, moxibustion/warming, acupuncture, and stone therapy have separate specific formulas. Nourishing and guiding exercises are attached hereafter.
The *Yangsheng Fang · Daoyin Method* states: Lie supine, extend both legs, inhale through the nose, exert yourself to the limit, breathing seven times, then shake the feet thirty times and stop. This eliminates cold feet and Jue reversal.
