[Suming Decoction] Treats stroke fei (stroke with flaccidity), characterized by the body's inability to control itself, inability to speak, mental confusion with unawareness of pain locations, or limb stiffness and rigidity preventing turning over.
Prescription composition: Ephedrae Herba (Mahuang), Cinnamon Twig (Guizhi), Gypsum Fibrosum (Shigao), Dried Ginger (Ganjiang), Apricot Seed (Xingren, 40 seeds), Ligusticum Chuanxiong Rhizome (Chuanxiong), Angelica Sinensis Radix (Danggui), Ginseng Radix (Renshen), Licorice Root (Gancao), each 3 liang. The above nine ingredients are decocted in 10 dou of water until reduced to 4 sheng. Take 1 sheng warm per dose; a slight sweating should occur after administration. Cover the back lightly with a thin cloth, sit leaning against a table; recovery occurs when sweat appears. If no sweat occurs, administer again. There are no specific dietary restrictions, but avoid exposure to wind. It also treats conditions with hidden pulse, inability to lie flat, cough with rebellious qi, and edema of the face and eyes.

[Collected Annotations] Zhao Liang stated: Fei disease is caused by Ying-Wei Qi and Blood failing to nourish the interior and exterior of the body, resulting in the body's dysfunction, joint immobility, and disordered spirit. However, this syndrome has deficiency and excess types. Deficiency type arises from improper diet, sexual exhaustion, or emotional injury, as described in the *Neijing*: "Internal depletion leading to syncope results in aphasia and fei." Excess type arises from contraction of Wind-Cold-Damp-Heat pathogens. Deficiency syndromes must not be treated as excess; treating them as such would further scatter their Qi and Blood. This formula explicitly states it treats stroke fei due to excess pathogens in Ying-Wei, hence the use of Suming Decoction. Suming Decoction is a modification of Mahuang Tang, adding Dried Ginger to open blood vessels affected by Cold, Gypsum to release muscle-level Wind, Angelica Sinensis Radix to harmonize blood, Ginseng Radix to tonify Qi, and Ligusticum Chuanxiong Rhizome to move blood and scatter Wind. The concomitant treatment of cough, rebellious qi, and facial edema is also attributed to Wind-Cold.

[Sansheng Yin] Treats sudden stroke with facial deviation, hemiplegia, as well as Phlegm Jue (syncope due to phlegm) and Qi Jue (syncope due to qi stagnation).
Prescription composition: Arisaemae Rhizoma (Tian Nanxing, raw) 1 liang, Aconitum Carmichaelii Radix Preparata (Chuan Wu, peeled, raw) 5 qian, Aconiti Lateralis Radix Preparata (Fuzi, peeled, raw) 5 qian, Costus Root (Muxiang) 2 qian. For each dose, take 5 qian of these herbs, decoct in ginger water; add Ginseng Radix (Renshen) 1 liang.

[Collected Annotations] Ke Qin stated: Wind is a Yang pathogen; if Wind exists without Cold, the damage is not severe. Harm becomes severe only when Wind carries Cold. If Cold is mild and located in the exterior, diaphoresis is suitable to expel the pathogen; if Cold is severe and enters the interior, warming the middle and tonifying deficiency are indispensable for salvation. This formula selects three substances (Arisaema, Chuan Wu, Fuzi) that are extremely pungent and hot, used unprocessed, assisted by Costus Root, utilizing their extreme rigidity and sharpness. This is not merely for treating Wind but also concurrently treating Cold. However, where pathogens gather, Zheng Qi (Upright Qi) must be deficient. If one only knows how to courageously attack pathogens while Zheng Qi is too weak to support, will there not be the risk of counterattack? One must use a large amount of Ginseng Radix to control the pathogen. This is Xue Ji's profound insight, establishing an invincible position to achieve complete efficacy. Incompetent physicians, fearing that tonification would retain pathogens, dare not use it. This aligns with Qibo's admonition: "Carefully master Yin and Yang, do not consult with the multitude." Observing that each dose is 5 qian, four doses are required for the pathogen to exit; modern practitioners, using Wu Tou and Fu Zi, often process them thoroughly before use and monitor them with Scutellaria Baicalensis Root (Huangqin) and Gardenia Fruit (Zhuzi). How can they rescue such critical conditions? The ancients were superior to the moderns, truly so. Removing Wu Tou and Fu Zi from this formula yields Xingxiang San, which is sufficient for treating Phlegm Jue and Qi Jue.
