Zhang Jingyue stated: The syndrome of Jue Ni (Jue-Ni, a critical condition characterized by cold limbs and loss of consciousness) is a critical illness. The *Neijing* (Classic of Internal Medicine) places special emphasis on it and discusses it in detail. For instance, it mentions "Cu Jue" (Sudden Jue) and "Bao Jue" (Violent Jue), which are general terms for Jue Ni; "Han Jue" (Cold Jue) and "Re Jue" (Hot Jue) differentiate the Yin and Yang aspects of Jue Ni; "Lian Jing" (Meridian Involvement) and "Lian Zang" (Organ Involvement) discuss the prognosis of life and death in Jue Ni. In recent times, there are also syndromes such as Qi Jue (Qi Jue), Xue Jue (Blood Jue), Tan Jue (Phlegm Jue), Jiu Jue (Alcohol Jue), Shi Jue (Corpse Jue), Zang Jue (Viscera Jue), and Hui Jue (Roundworm Jue). Zhang Zhongjing also discussed the Yin and Yang of Jue caused by Shang Han (Cold Damage). However, Zhang Zhongjing's discussion of Shang Han Jue focuses on distinguishing pathogenic factors; therefore, Han Jue is suitable for warming methods, and Re Jue is suitable for purging methods. The *Neijing*'s discussion of Jue emphasizes Yuan Qi (Primal Qi); thus, Re Jue should be treated by nourishing Yin, and Han Jue by tonifying Yang. All the above syndromes are currently mistaken for Feng Zhong (Wind Stroke), without realizing that they all belong to non-wind syndromes.

1. There are two types of Qi Jue: Qi Xu (Qi Deficiency) and Qi Shi (Qi Excess). When sudden collapse occurs due to Qi Xu, the patient invariably exhibits depleted physical energy, cyanotic or pale complexion, slight body coldness, and a weak and faint pulse. This is a syndrome of Qi Tuo (Qi Collapse). It is suitable to use Ren Shen (Ginseng Radix et Rhizoma), [missing character], Dang Gui (Angelicae Sinensis Radix), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Di Huang (Rehmanniae Radix), Gou Qi Zi (Lycii Fructus), Da Bu Yuan Jian (Great Tonification Decoction), and for severe cases, Hui Yang Yin (Decoction to Restore Yang) or Du Shen Tang (Single Ginseng Decoction). For Qi Shi patients, the physical demeanor shows angry and vigorous Qi, the pulse is deep, weak, and slippery, with wheezing and fullness in the chest and diaphragm. This is a syndrome of Qi Ni (Qi Rebellion). The Classics state: "Great anger causes the form and Qi to sever, and blood stagnates in the upper part." Treatment should prioritize using Pai Qi Yin (Qi-Dispersing Decoction), Si Mo Yin (Four-Mortar Decoction), Ba Wei Shun Qi San (Eight-Ingredient Qi-Soothing Powder), or Su He Xiang Wan (Styrax Pill) to first smooth the Qi, and then regulate according to deficiency or excess. If anger damages the Qi mechanism, the rebellious Qi dissipates quickly, but the True Qi is damaged. Furthermore, for those who are prone to melancholy and fear, leading to timid and sinking Qi, one must not use Qi-moving and stagnation-breaking herbs.

2. There are two types of Xue Jue: Xue Tuo (Blood Collapse) and Xue Ni (Blood Rebellion). Xue Tuo occurs like massive hemorrhage or severe vomiting, or after childbirth when blood loss is complete, causing Qi to follow and collapse, resulting in sudden falling and apparent death. One should first press the Ren Zhong acupoint (GV26) or burn vinegar-soaked charcoal to inhale the fumes to gather the Qi. Urgently administer one or two liang of Ren Shen decoction to灌 (irrigate/administer) so that Qi does not completely collapse, and the patient will gradually revive. Then, adjust slowly according to cold or heat. This is the method of "Tonifying Qi for Blood Collapse." If blood-nourishing herbs and cold-cooling hemostatics are used, the patient will certainly die. Xue Ni refers to what the Classics say: "Blood and Qi move together to the upper part," and "Great anger causes the form and Qi to sever, and blood stagnates in the upper part." Since blood follows Qi rebellion, one must first regulate the Qi; when Qi moves, blood will flow without obstruction. It is suitable to use Tong Yu Jian (Stasis-Unblocking Decoction) or Hua Gan Jian (Liver-Transforming Decoction). Wait until blood flows and Qi relaxes, then treat according to symptoms.

3. There are two types of Se Jue (Sexual Jue): Bao Tuo (Sudden Collapse) and Dong Xue (Blood Movement). Bao Tuo occurs because the person is originally deficient, and occasionally encounters unexpected joyful events, striving excessively; or has loved each other for a long time, indulging in sexual desires to exhaustion. Thus, after the act, Qi leaves with the essence, causing sudden collapse that cannot return. One should immediately press Ren Zhong (GV26), keep the female partner holding firmly, face-to-face, ensuring warm breath passes through to reconnect the Qi, preventing total loss to preserve the Shen (Spirit). Quickly administer Du Shen Tang (Single Ginseng Decoction), or moxa Qihai (CV6) for dozens of moxibustion units to restore Yang Qi, hopefully saving the life. There are also cases where the disease does not appear immediately but develops later, due to frequent essence depletion and gradual Qi collapse. This often appears two or three days after sexual activity, and people after middle age are prone to this. These are all called Se Jue. Treatment should focus on tonifying Ming Men (Gate of Life), whether tonifying Water or Fire, according to appropriateness. For Se Jue involving blood movement, since Qi and Blood move together to the upper part, it differs from blood rebellion due to great anger. This is due to Desire Fire flaming upward, so blood follows Qi upward. This happens when desire is extreme, unfulfilled, or suppressed by alcohol. Symptoms include sudden violent hematemesis, persistent epistaxis, Jue Ni with sweating, wheezing, and coughing. These are all caused by Yin Fire rushing upward. Treatment must first control the fire to suppress its momentum, using Xiao Hua Yin (Digestion-Decoction) or Si Yin Jian (Four-Yin Decoction). If there is Yin exhaustion below and Fire not returning to its source, there will be no irritability or heat-related pulse/symptoms. In critical Xue Jue, only Zhen Yin Jian (Yin-Stabilizing Decoction) can save the patient. After the condition stabilizes, treat according to symptoms.

4. For Tan Jue (Phlegm Jue) syndrome, where Phlegm obstructs and Qi closes, one should use emetics or opening-orifice methods to treat the branch symptom. Once Phlegm-Qi is slightly opened, treat the root cause. If caused by Fire, clear and descend it; if caused by Wind-Cold, disperse and warm it; if caused by Dampness, dry and promote diuresis; if caused by Pi Xu (Spleen Deficiency), tonify the Spleen; if caused by Shen Xu (Kidney Deficiency), tonify the Kidney. Treat the cause of the Phlegm, and the Phlegm will clear itself. However, there are cases where treating Phlegm directly is contraindicated; attacking it too aggressively will only increase Phlegm production.
