此症人多治木、治金固是，而不知胃土之为尤切。当治胃土，且有经、脉之分。
经云∶“足阳明之经，急则口目为僻， 急不能视”，此胃土之经为歪邪也。又云∶“足阳明之脉，挟口环唇，
口歪唇邪”，此胃土之脉为歪邪也。
二者治法，皆当用∶
黄 当归 人参 白芍 甘草 桂枝 升麻 葛根 秦艽 白芷 防风 黄柏 苏木 红花
水、酒各半煎，微热服。如初起有外感者，加葱白三茎同煎，取微汗自愈。
〔人病口眼歪斜，人以为胃中之痰，不知非也。〕乃心中虚极，不能运于口目之间，轻则歪斜，重则不语。方用∶
人参（三钱） 白术（五钱） 茯苓（三钱） 甘草（一钱） 当归（一两） 白芍（三钱） 菖蒲（三钱） 肉
桂（二钱）
水煎服。
一剂少愈，二剂痊愈。〔此方之妙，全不去祛风祛邪，一味补正，而歪斜自愈矣。〕
此症宜于心、胃而调理之。盖心为天真。神机开发之本；胃是后腑，充大真气之标。标本相得，则心膈开之，
膻中、气海，所留宗气盈溢，分布五脏、三焦，上下中外，无不周遍。
若标本相失，则不能致其气于气海，而宗气散矣。故分布不周于经脉则偏枯；不周于五脏则 。即此言之，
未有不因真气不周而病者也。
法宜用黄 为君，参归、白芍为臣，防风、桂枝、钩藤、竹沥、姜汁、韭汁、葛汁、梨汁、乳汁为佐使，治
之而愈。
若杂投乌附、羌活之类，以涸荣而耗卫，如此死者，是医杀之也。
For this condition, people often treat it by addressing Liver Wood and Lung Metal, which is indeed correct, but they fail to realize that treating Stomach Earth is even more critical. One should treat Stomach Earth, distinguishing between the meridians (Jing) and the collaterals/vessels (Mai).
The Classics state: "When the Foot-Yangming Meridian is tense/spasmodic, the mouth and eyes become deviated, and vision is impaired," indicating that the deviation is due to the Foot-Yangming Meridian of Stomach Earth. It also states: "The Foot-Yangming Vessel runs alongside the mouth and circles the lips," indicating that if the mouth is deviated and lips are slanted, it is due to the Foot-Yangming Vessel of Stomach Earth.
The treatment for both conditions should utilize the following formula:
Huangqi (Astragali Radix), Danggui (Angelicae Sinensis Radix), Renshen (Ginseng Radix), Baishao (Paeoniae Radix Alba), Gancao (Glycyrrhizae Radix et Rhizoma), Guizhi (Cinnamomi Ramulus), Shengma (Cimicifugae Rhizoma), Gegen (Puerariae Lobatae Radix), Qinjiao (Gentianae Macrophyllae Radix), Baizhi (Angelicae Dahuricae Radix), Fangfeng (Saposhnikoviae Radix), Huangbai (Phellodendri Cortex), Sumu (Sappan Lignum), Honghua (Carthami Flos).
Decoct with half water and half wine, and take warm. If there are external pathogenic factors at the onset, add three stalks of Congbai (Allii Fistulosi Bulbus) to decoct together; inducing slight sweating will lead to self-healing.
[People suffering from facial paralysis often attribute it to phlegm in the Stomach, but this is incorrect.] It is actually caused by extreme deficiency in the Heart, preventing the transportation of Qi and Blood to the mouth and eyes. Mild cases result in deviation, while severe cases lead to aphasia. The prescription is:
Renshen (Ginseng Radix) (3 qian), Baizhu (Atractylodis Macrocephalae Rhizoma) (5 qian), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma) (1 qian), Danggui (Angelicae Sinensis Radix) (1 liang), Baishao (Paeoniae Radix Alba) (3 qian), Changpu (Acori Tatarinowii Rhizoma) (3 qian), Rougui (Cinnamomi Cortex) (2 qian).
Decoct with water and take orally.
After one dose, symptoms improve slightly; after two doses, full recovery occurs. [The brilliance of this formula lies not in dispelling wind or evil pathogens, but solely in tonifying the righteous Qi, whereby the deviation heals itself.]
This condition is suitable for regulation through the Heart and Stomach. The Heart is the root of the development of innate spirit and mental activity; the Stomach is a posterior fu-organ and the manifestation of filling the great true Qi. When root and manifestation are harmonious, the chest and diaphragm open, allowing the Zongqi (Gathering Qi) stored in Danzhong (CV17) and Qihai (CV6) to overflow and distribute throughout the five zang-organs and Sanjiao (Triple Burner), covering all upper, lower, interior, and exterior aspects without omission.
If root and manifestation are discordant, Qi cannot be directed to Qihai, causing Zongqi to scatter. Thus, if distribution to the meridians is incomplete, hemiplegia (Pianku) results; if distribution to the five zang-organs is incomplete, organ dysfunction ensues. From this perspective, no illness arises without the failure of True Qi to circulate uniformly.
The method should use Huangqi (Astragali Radix) as the Sovereign herb, Renshen (Ginseng Radix), Danggui (Angelicae Sinensis Radix), and Baishao (Paeoniae Radix Alba) as Ministers, and Fangfeng (Saposhnikoviae Radix), Guizhi (Cinnamomi Ramulus), Gouteng (Uncariae Ramulus cum Uncis), Zhuli (Bambusae Sap), Jiangzhi (Zingiberis Juice), Jiuji (Allii Tuberosi Juice), Gezhi (Puerariae Juice), Lizhi (Piriformis Fructus Juice), and Nairu (Human Milk) as Assistants and Guides. Treatment will lead to recovery.
If one indiscriminately administers herbs such as Wutou (Aconiti Lateralis Radix Preparata), Fuzi (Aconiti Radix Preparata), or Qianghuo (Notopterygii Rhizoma et Radix), thereby depleting Ying (Nutritive) blood and consuming Wei (Defensive) Qi, death resulting from such practice is effectively murder by the physician.
