The pulse of Yang Jue (Yang Reversal) is slippery and deep-solid. The pulse of Yin Jue (Yin Reversal) is fine and deep-hidden.
Qi deficiency leads to the onset of Jue. Blood deficiency leads to fever. "Jue" refers to coldness in the hands and feet. Qi belongs to Yang; when Yang Qi is deficient, Yin pathogens gather, thus causing Jue. Blood belongs to Yin; when Yin Blood is deficient, Yang pathogens gather, thus causing fever. For Jue caused by Qi deficiency, warm-natured medicines should be used. For fever caused by Blood deficiency, cool-cold medicines are not suitable; instead, medicines that warm and nourish Qi and Blood should be used for tonification, with an emphasis on nourishing Yin, such as Huangqi Jianzhong Tang (Astragalus Decoction to Build the Middle).
There is also a condition characterized by excess heat, where extreme heat results in coldness of the hands and feet. This is referred to as "the deeper the heat, the deeper the Jue." In this case, cool-cold medicines should be used, and differentiation must be made based on the pulse. This is the most difficult to distinguish.

One discussion on Yang Jue states that it occurs when heat is profound, leading to profound Jue, because extreme Yang leads to Jue. It should be treated urgently with Liuyi Shunqi Tang (Six-One Regulating Qi Decoction).
One discussion on Yin Jue states that initially, the body is cold, the pulse is deep, the four limbs are reversed (cold), the legs are curled up in bed, the lips and mouth are bluish, or there is spontaneous diarrhea without thirst, and the urine is clear white. Formulas such as Sini Tang (Frigid Extremities Decoction) or Lizhong Tang (Regulate the Middle Decoction) are appropriate. Additionally, moxibustion should be applied rapidly to the Guanyuan (CV-4) acupoint for one hundred burns, stopping when sweat appears on the tip of the nose.
One discussion on Tan Jue (Phlegm Reversal) describes sudden loss of consciousness accompanied by phlegm rattle in the throat resembling the sound of a water fowl. Use equal parts of Ya Zao (Gleditsia Sinensis Fruit) and Bai Fan (Alum), grind into powder, and insufflate into the nose. Immediately administer one cup of Sesame Oil mixed with a little Ginger Juice orally, and the patient will awaken immediately. Alternatively, administering Bamboo Sap (Zhu Li) and Ginger Juice prepared by heating is also effective.
One discussion on Hui Jue (Roundworm Reversal) attributes it to Cold in the Stomach. The classics state: "Roundworms are long worms." When the Stomach is cold, roundworms are vomited. Lizhong Tang (Regulate the Middle Decoction) should be used with five fried Sichuan Peppercorns (Chuan Chuanjiao) and two grams of Areca Seed (Binglang) added, taken together with Wumei Wan (Mume Pill).
One discussion on Qi Jue (Qi Reversal) notes that it resembles Zhong Feng (Wind Stroke), but patients with Wind Stroke have warm bodies, whereas those with Qi Jue have cold bodies. Huoxiang Zhengqi San (Agastache Powder to Rectify the Qi) can be used, augmented with Nan Xing (Arisaema Cum Bile), Mu Xiang (Costus Root), and Wu Yao (Lindera Root). If phlegm is present, Sixian Daotan Tang (Six-Man Phlegm-Resolving Decoction) is the primary formula.
One discussion on death due to sudden rage names it Qi Jue. Anger causes Qi to ascend; when Qi ascends, Upper Jiao Qi becomes excessive and fails to descend, while Lower Jiao Qi rebels and fails to inhale, leading to sudden death. For ascending Qi, descending methods should be employed. Wumo Yinzi (Five-Monk Drink) consists of Mu Xiang (Costus Root), Chen Xiang (Aquilaria Wood), Binglang (Areca Seed), Zhishi (Immature Bitter Orange), and Tai Wuyao (Lindera Root). These five herbs in equal proportions are ground with White Wine and administered orally, yielding immediate effects.
