凡阴阳不相顺接便为厥也。《经》曰∶手之三阴，从腹走手，手之三阳，从手走
头。足之三阳，从头走足，足之三阴，从足走腹，是三阴三阳，俱相接于手足者也。阳
气内陷，不与阴气相顺接，故手足逆冷也。然有阴厥，有阳厥，阴衰于下则热，阳衰于
下则寒，故阳厥者。是热深则厥，盖阳极则发厥也，不可作阴症而用热药治之，否则精
魄绝而死矣，急宜大小承气汤，随其轻重治之。阴厥者，始得之身冷脉沉，四肢逆，足
蜷卧，唇口青或自利不渴，小便色白，此其候也，治之以四逆理中之类。尸厥者，飞尸
卒厥也。此即中恶之候，因犯不正之气，忽然手足逆冷，肌肤粟起，头而青黑，精神不
守，或错言妄语，牙紧口噤，或昏不知人，头旋晕倒，此是卒厥客忤，飞尸鬼击，凡吊
死问丧，入庙登冢，多有此病，以苏合香丸灌之。候稍苏，随症调治。痰厥者，乃寒痰
迷闷，四肢逆冷，宜姜附汤，以生附代熟附。蛔厥者，乃胃寒所主。《经》曰∶蛔者，
长虫也。胃中冷即吐蛔，宜理中汤加炒川椒五粒，槟榔五分，吞乌梅丸效。蛔见椒则伏
也。气厥者，与中风相似，何以别之？风中身温，气中身冷，以八味丸顺气散或调气散
之类。食厥者，醉饱后感风寒，着恼怒而致，治宜吐之。手足麻者属气虚，手足十指
麻木，丹溪谓胃中湿痰死血，然中气不足，不能达四肢者居多。
凡是阴阳之气不能顺利交接，就称为厥证。《黄帝内经》说：手部的三条阴经，从腹部走向手部；手部的三条阳经，从手部走向头部。足部的三条阳经，从头部走向足部；足部的三条阴经，从足部走向腹部。这三阴三阳经脉，都在手足部位相互交接。如果阳气内陷，不能与阴气顺利交接，就会导致手足逆冷。然而，厥证有阴厥和阳厥之分。阴气衰于下部则生热，阳气衰于下部则生寒。所以阳厥证，是热邪深重导致厥逆，这是因为阳极而发厥，不可当作阴证而用热药治疗，否则会导致精气神断绝而死，应当紧急使用大承气汤或小承气汤，根据病情的轻重进行治疗。阴厥证，初起时身体寒冷、脉象沉细、四肢逆冷、足部蜷缩卧倒、嘴唇口唇发青或自行腹泻且不口渴、小便颜色清白，这是其征候，治疗应用四逆汤、理中汤之类的方剂。尸厥证，即飞尸卒厥。这属于中恶的征候，因为触犯不正之气，突然手足逆冷，肌肤出现鸡皮疙瘩，头面呈现青黑色，精神不能守舍，或者胡言乱语、牙关紧闭、口噤不开，或者昏迷不省人事、头晕跌倒，这是卒厥客忤、飞尸鬼击之症。凡是在吊丧问疾、进入庙宇登上坟墓等场合，多有此病，可用苏合香丸灌服。待患者稍苏醒后，再根据症状进行调理治疗。痰厥证，是由于寒痰迷闷所致，表现为四肢逆冷，适宜使用姜附汤，以生附子代替熟附子。蛔厥证，是由胃寒引起的。《黄帝内经》说：蛔虫属于长虫。胃中寒冷就会吐出蛔虫，适宜使用理中汤加入炒川椒五粒、槟榔五分，吞服乌梅丸效果显著。蛔虫见到花椒就会伏藏。气厥证，与中风相似，如何区别呢？中风时身体温暖，气中（气厥）时身体寒冷，可用八味丸、顺气散或调气散之类的方剂治疗。食厥证，是由于醉饱后感受风寒，加之恼怒而导致的，治疗适宜采用催吐法。手足麻木属于气虚，手足十指麻木，朱丹溪认为是胃中有湿痰和死血，但实际上中气不足，不能达于四肢的情况居多。
See the section on Foot Diseases mentioned earlier. For various formulas in the Flaccidity Syndrome (Wei Zheng) section, please refer to the aforementioned Foot Diseases section.
Any condition where Yin and Yang Qi fail to connect smoothly is termed Jue Syndrome (Jue Zheng). The *Classic of Medicine* (*Huangdi Neijing*) states: The three Yin meridians of the hand run from the abdomen to the hand; the three Yang meridians of the hand run from the hand to the head. The three Yang meridians of the foot run from the head to the foot; the three Yin meridians of the foot run from the foot to the abdomen. Thus, the three Yin and three Yang meridians all connect at the hands and feet. If Yang Qi sinks inward and fails to connect smoothly with Yin Qi, it results in cold extremities (cold reversal of hands and feet). However, there are Yin Jue and Yang Jue. When Yin declines in the lower part, heat arises; when Yang declines in the lower part, cold arises. Therefore, in Yang Jue, deep heat leads to Jue, as extreme Yang triggers Jue. It must not be treated as a Yin syndrome using hot medicines, otherwise, the essence and spirit will be severed, leading to death. One should urgently use Da Chengqi Tang (Major Order the Qi Decoction) or Xiao Chengqi Tang (Minor Order the Qi Decoction), treating according to the severity of the condition. In Yin Jue, initially, the body is cold, the pulse is deep, the four limbs are cold, the legs are curled up, the lips and mouth are cyanotic, or there is spontaneous diarrhea without thirst, and the urine is clear and white; these are its signs. Treatment should employ formulas such as Sini Tang (Frigid Extremities Decoction) or Lizhong Tang (Regulate the Middle Decoction). Shijue (Corpse Jue) refers to Feishi Cu jue (Flying Corpse Sudden Jue). This is a sign of Zhong E (Sudden Evil Invasion), caused by exposure to abnormal qi, resulting in sudden cold extremities, skin covered with gooseflesh, a bluish-black complexion, loss of mental control, delirious speech, clenched teeth, locked jaw, coma, dizziness, or fainting. This is sudden Jue due to guest hostility, flying corpse, or ghost strike. Such conditions often occur when attending funerals, visiting mourning houses, entering temples, or climbing tombs. They should be treated by administering Suhexiang Wan (Styrax Pill). Once the patient regains slight consciousness, treatment should be adjusted according to symptoms. Tan Jue (Phlegm Jue) is caused by cold phlegm confusing and obstructing, presenting with cold extremities. Jiangfu Tang (Ginger and Aconite Decoction) is suitable, using raw Fuzi (Raw Radix Aconiti Lateralis Preparata) instead of cooked Fuzi. Hui Jue (Roundworm Jue) is governed by stomach cold. The *Classic* states: Roundworms are long parasites. Cold in the stomach causes vomiting of roundworms. Lizhong Tang (Regulate the Middle Decoction) added with five fried Chuanjiao (Fructus Zanthoxyli) and 0.5 fen of Binglang (Areca Seed) is effective, along with swallowing Wumei Wan (Mume Pill). Roundworms subside upon encountering pepper. Qi Jue (Qi Jue) resembles Wind Stroke (Zhong Feng). How to distinguish them? In wind stroke, the body is warm; in Qi Jue, the body is cold. Formulas such as Bawei Wan (Eight-Ingredient Pill), Shunqi San (Smooth Qi Powder), or Tiaoqi San (Regulate Qi Powder) can be used. Shi Jue (Food Jue) is caused by contracting wind-cold after excessive eating and drinking, combined with anger. Treatment is appropriate via emesis. Numbness of the hands and feet belongs to Qi deficiency. Numbness of the ten fingers of the hands and feet: Zhu Danxi attributed this to damp-phlegm and dead blood in the stomach. However, most cases are due to insufficiency of Middle Qi, which fails to reach the four limbs.
