Cold and heat pathogens, if only treated with thin decoctions or dietary adjustments, cannot resolve issues of Qi and Blood; Shi Jue (Corpse Jue), Tan Jue (Phlegm Jue), and Hui Jue (Roundworm Jue) are collectively referred to as types within the "Ten Jues." One must deeply understand that this syndrome has a high mortality rate, whereas sudden diseases of the Shen Zhu (Eye) are rare.

The foundation of life relies on the Five Elements: Wood, Fire, Earth, Metal, and Water. They circulate and interact, generating endlessly without cessation. If these elements are excessive or deficient, leading to deep stagnation (Yu), recovery can be achieved through methods of unblocking (Da), dispersing (Fa), purging/robbery (Duo), draining (Xie), and restraining (Zhe).

This chapter discusses eye diseases caused by stagnation, which subsequently lead to Jue syndromes. There are five treatment methods for addressing stagnation. The *Classic* states: For Wood stagnation, unblock it; for Fire stagnation, disperse it; for Earth stagnation, purge/rob it; for Metal stagnation, drain it; for Water stagnation, restrain it. "Da" (Unblock) implies promoting smooth growth and flow. The Liver is impetuous; anger causes Qi rebellion, leading to hypochondriac pain, armpit pain, and frequent upward flare-up of Fire. Treatment uses acrid-dispersing methods. If ineffective, Xiaoyao San (Free Wanderer Powder) is used, or ascending-dispersing herbs combined with Jueyin meridian guiding drugs for counter-treatment. Long-standing Wind entering the interior causing undigested stool diarrhea is treated with clear-and-rising agents, such as Sijunzi Tang (Four Gentlemen Decoction) added with Guizhi Twig (Cinnamon Twig) and Shaoyao (Peony Root) to lift and disperse. All such cases belong to the method of "Da." Commentators on the *Neijing* state: "Da" means vomiting. Although vomiting contains the meaning of dispersion, can one simply use "vomiting" to encompass "Da"? "Fa" (Disperse) is annotated as sweating. Dongyuan's Shengyang Sanhuo Tang (Raise Yang Disperse Fire Decoction) works by exhausting the pathogenic force until it ceases. In reality, "Fa" and "Da" are not far apart. Since Fire resides within Wood, Wood stagnation leads to Fire stagnation; thus, using drugs that unblock also dispels the Fire, yielding effective results. "Duo" (Purge/Rob) is annotated as purgation. For severe abdominal fullness and distension, harsh saline-cold purgatives are required to劫夺 (rob/seize) the pathogenic force; otherwise, it cannot be平息 (calmed). However, when food blocks the Stomach, causing Jue with loss of consciousness, failure to vomit leads to death. Therefore, vomiting is the superior "Duo" method to weaken Earth-Stomach stagnation. The *Classic* says: "For those high above, cause them to ascend/vomit." Is this not Duo? As for "Xie" (Drain), it refers to渗泄 (percolating/drainage), releasing the exterior, and promoting urination. The Lung governs skin and hair. Even if various Qi stagnate, releasing the exterior allows Metal Qi to flow freely. Adding drainage/percolation may not only involve Water stagnation but also risk emptying the deficiency, worsening the stagnation. "Zhe" (Restrain) means controlling rebellious rushing Qi, which is indeed a profound interpretation. However, regulating Qi involves restraining excess because each element fears its controller. Regarding "Xie" (Draining/Purging), one must comprehend that water passages rely on Qi transformation; if Qi stops, transformation ceases. If not restrained when excessive, stagnation will transform into Jue. Thus, "Zhe" requires skill. One may harmonize left and right, warm Kidney Qi, allowing Qi movement to dissipate stagnation. Or tonify Middle and boost Qi, raise Lung Qi, opening upper apertures so lower apertures naturally open. Or strengthen the Center to aid Spleen Earth, using what it fears to control it. This non-draining approach to draining is what is meant by Xie. Danxi stated: When Qi and Blood are harmonious, no disease arises; once there is frustration/stagnation, it originates here. He formulated the Theory of Six Stagnations: Qi, Dampness, Heat, Phlegm, Blood, and Food. He believed Qi stagnation precedes the others; Qi stagnation leads to Dampness stagnation, which leads to Heat, which leads to Phlegm, which obstructs Blood flow, preventing digestion of Food. These six cause disease mutually. Thus, Yueju Wan (Yueju Pill) was created to treat stagnation. Xue Shi modified Yueju Wan into Xiaoyao San, with additions and subtractions, which is particularly balanced.

There are ten types of Jue: When Yang Qi is deficient, Yin Qi inevitably invades, causing cold from the fingertips to the knees, called Han Jue (Cold Jue), indicating Cold rebelling below. Treat with Liuwu Fuzi Tang (Six-Ingredient Aconite Decoction) or Bawu Huiyang Yin (Eight-Ingredient Restore Yang Drink). When Yin retreats and Yang advances, Yin deficiency below causes Yang to gather below, causing heat in the soles. If severe, it ascends along the Three Yin meridians, called Re Jue (Heat Jue). Treat with Liuwei Dihuang Tang (Six-Ingredient Rehmannia Pill). Violent anger causes Fire to rise, agitating Blood upward, causing Blood to pool above and Qi to disorder in the middle. Blood and Qi clash, causing Jue, called Bo Jue (Clashing Jue). Treat with Puhuang Tang (Polygonatum Pollen Decoction). Movements belong to Yang; vexation expands Yang Qi, making Labor-Fire hyperactive. Fire flares, drying Water, leading to Essence depletion. Over time, accumulating until summer, internal and external heat combine, solitary Yang flies away, feeling like frying or killing, called Jian Jue (Frying Jue). Treat with Renshen Guben Wan (Ginseng Solidify Root Pill). The Qi of the Five Corpses violently invades, disrupting Yin and Yang, separating Form and Qi, preventing connection, causing sudden Jue resembling death, called Shi Jue (Corpse Jue). Treat with Ershisi Wei Liuqi Yin (Twenty-Four-Ingredient Moving Qi Decoction) or Suhe Xiang Wan (Styrax Pill). Cold Phlegm confusing and stifling, with cold limbs, is Tan Jue (Phlegm Jue). Vomiting roundworms is Hui Jue (Roundworm Jue). Both should use Jiangfu Tang (Ginger and Aconite Decoction); otherwise, Wumei Wan (Mume Pill) or Lizhong Tang (Regulate the Middle Decoction). Qi is the Yang of the body; once frustrated, Yang cannot reach the four extremities, causing cold hands and feet, called Qi Jue (Qi Jue). It resembles Zhongfeng (Wind Stroke), but Zhongfeng presents with warm body, whereas this presents with cold body. Treat with Bawu Shunqi San (Eight-Ingredient Smooth Qi Powder). Doubling food intake while having a cold causes Stomach Qi to stagnate, Yang merging above, leading to sudden coma. The upper half is stuffy and hot, or vexed with headache; the lower half is colder than ice, unwarmed even by a furnace. This is Shi Jue (Food Jue). Physicians mistaking it for Yin-Cold or Wind Stroke and applying warming/tonifying treatments cause immediate death. Use Yangyin Dansalt Soup (Yin-Yang Light Salt Decoction) to induce vomiting; recovery follows expulsion of food. Alternatively, Pingwei San (Pingwei Powder) modified or Baohe Wan (Preserve Harmony Pill). Excessive sweating reduces Blood and merges Qi; Blood rises but does not descend, Qi also blocks, suddenly resembling death. After Qi passes and Blood returns, Yin and Yang reconnect, waking after some time. This is Xue Jue (Blood Jue), common in women. Treat with Baiwei Tang (Baiwei Decoction) or Cangong San (Master Cang's Powder). In summary, Ten Jues and Five Stagnations present similarly, but treatments vary greatly. Attain the meaning and forget the words; do not merely adhere to established formulas.
