He (referring to He Hanzhong or a general reference to previous authorities) stated (details omitted).

Upon careful examination, Jue syndrome (syncope with cold limbs) involving cold and heat also presents differences in Yin-Yang deficiency and excess. If the patient's physical constitution and Zheng Qi (Upright Qi) are slightly robust, it is appropriate to adopt He's method of inducing vomiting or purging. If the deficiency is severe, one should only regulate according to the specific etiology.

Chen discussed that when Zang-Fu Qi mutually overcomes each other or conflicts with external pathogens, Qi stagnation occurs, blocking meridians and vessels, leading to coma and unconsciousness, known as "Shi Jue" (Corpse Syncope). Currently, the common practice often treats this as Wind disease, rarely avoiding fatal outcomes. For instance, citing Hua Tuo's treatment of the Crown Prince of Guo for Shi Jue: Yang pulses sink downward, Yin pulses surge upward, causing Qi and Blood obstruction. There are severed Yang collaterals above and broken Yin tendons below. The complexion reflects broken Yin and severed Yang, pulse chaos ensues, thus the body appears still as if dead. This aligns subtly with the principle in the *Classic of Difficult Issues* regarding Jue caused by Yin-Yang Qi imbalance. How can later generations grasp its diagnostic and therapeutic nuances? Treating based on Yin-Yang differentiation is verifiable.

In contrast, in Shanghan (Cold Damage), hand-foot Jue with coma indicates extreme struggle between pathogenic factors and healthy Qi. Slight delay in warming Yang may lead to immediate disaster. Post-sweating failure to resolve, sudden epistaxis with coma and Jue; or miscellaneous diseases presenting with vomiting, epistaxis, coma, and Jue, will likely show intermittent relief after one to three days. Intermittency indicates recovery. This is because Yin Qi is still substantial; absence of fever implies no Jue. If fever occurs, Jue does not happen. Jue implies lack of blood warmth; body fever indicates death.

Sudden Qi Jue with robust physique is often caused by Seven Emotions; Jue due to internal retention of Phlegm-Fluids requires half a day or one to two hours for intermittent relief. Those with weak physique and severe Qi rebellion often prove incurable. This demonstrates the severity of Qi-Blood pathology causing Jue and violent Yin-Yang rebellion. Therefore, it must not be diagnosed merely as Wind disease.

Suhe Xiang Wan (Styrax Pill): Treats sudden Jue with unconsciousness before distinguishing between Wind-Phlegm or Qi Jue. It is suitable to administer this pill mixed with ointment dissolved in thick decoction. After regaining consciousness, prescribe medication based on pulse and symptoms.

Emetic Formula: Gudi San (Melon Seed Powder). (See Phlegm-Fluid section). For patients with locked jaw, use nasal insufflation medicine first.

Sanyin Zhuihun Tang (Three Causes Soul-Chasing Decoction): Treats sudden Jue appearing as death, as well as attacks from Guest/Host interactions, Guiji (Ghost Strike), Feishi (Flying Corpse) causing Qi cessation, unconsciousness, and locked jaw.

Mahuang Tang (Ephedra Decoction). (See Cold section).

The above herbs should be coarse-chopped, decocted in water, and administered. If swallowing is difficult, have the patient lie on their left or right side, hold and press the shoulders to guide administration for efficacy. *Qianjin Fang* adds Guizhi (Cinnamon Twig).

Note: This is a formula for treating invasion by evil Qi.

Sini Tang (Frigid Extremities Decoction): Treats Han Jue (Cold Jue) manifesting as exterior heat and interior cold, diarrhea with undigested food, vomiting upon eating, deep and hidden pulse, and cold hands and feet.

(See Cold section).

Note: This is a formula for treating cold and heat, categorized under Cold and Summerheat examples. However, formulas for internal causes related to Qi and Blood are detailed in respective sections and should be selected according to syndrome differentiation; they are not recorded here in detail.
