（李东垣）
治疗风冷之邪乘人体正气虚弱之际，侵袭肠胃，导致完谷不化的飧泄和急迫的腹泻；以及肠风下血。又治疗因胃虚受风导致的能食但牙关紧闭、手足抽搐、肌肉跳动、面部浮肿的症状，这种病称为“胃风”（胃受风气侵袭，肝木邪气克制脾土，所以出现完谷不化，称为飧泄；阳明经脉在面部循行，所以面部浮肿。抽搐是指手足抽掣，跳动是指肌肉颤动）。
人参、白术（用土炒）、茯苓、当归（用酒炒）、川芎、芍药（用酒炒）、桂枝（炒）各等分。
加入粟米一百粒（煎服）。
这是足阳明胃经和足厥阴肝经的药物组合。所谓胃风，是胃气虚弱而风邪乘虚侵袭所致。风属于肝木，能够克制脾土，所以用人参、白术、茯苓来补益脾气以增益卫气；用当归、川芎来滋养肝血以调和营血；芍药可以疏泄肝气从而调和脾胃；肉桂可以疏散风邪从而平抑肝木（木材遇到桂枝就会枯萎，如同削去桂枝钉入树根，树木即死。另外辛味能发散风邪，所以能止住泄泻并治疗风湿。又说：白术、茯苓能强健脾胃而祛除湿气，川芎、肉桂能进入血分而驱除风邪。《玉机微义》说：这个方子名字叫治风，实际上并不是直接治风，而是通过补益正气来祛风）。
李东垣的胃风汤：升麻、白芷（一钱二分）、麻黄（不去节）、葛根（一钱）、柴胡、羌活、藁本、苍术、蔓荆子、草豆蔻、黄柏、当归、炙甘草（各五分）。加生姜、大枣煎服。也治疗胃风证（喻嘉言说：风邪侵入胃中为什么反而能进食？大概是因为风能生热，这符合《内经》中痹证转化为消中的道理。此方只去除风邪而不清除热邪，因为热邪必然会随着风邪一同解除。又说：必须加入竹沥、花粉、石膏、葳蕤、生地、梨汁等甘寒性质的药物，配合升麻、葛根、甘草作为药剂，才算恰当。有人问：这两个方子一个偏补一个偏散，却治疗同一种证候，为什么呢？喻嘉言说：按照《内经》所说，“风成为寒热”，这是风邪进入胃中，导致营卫之气偏胜的结果。此方是使胃中风邪从体表解出的药物；如果是久风导致的飧泄，则风邪已经入里，此时应当用人参为君药，桂枝、白术为臣药，茯苓、甘草为佐使药，在内祛除风邪，这是表里治疗的权衡之道。《内经》……）
(Li Dongyuan)
Treats wind-cold pathogenic factors taking advantage of deficiency to lodge in the intestines and stomach, causing sundry diarrhea (xun xie) with undigested food; as well as intestinal wind bleeding. It also treats conditions where wind deficiency allows for increased appetite, accompanied by lockjaw, convulsions of the hands and feet, muscle twitching, and facial swelling. This condition is named "Stomach Wind" (When the Stomach is affected by wind, Wood pathogenic factors overcome Earth, resulting in undigested food in stool, termed sundry diarrhea; the Yangming meridian circulates around the face, hence facial swelling. Convulsions refer to the jerking of limbs, twitching refers to muscle tremors).
Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Rhizoma, stir-fried with soil), Fu Ling (Poria), Dang Gui (Angelicae Sinensis Radix, stir-fried with wine), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Shao Yao (Paeoniae Radix Alba or Rubra, stir-fried with wine), Gui Zhi (Cinnamomi Ramulus, stir-fried) in equal parts.
Add one hundred grains of millet (decocted and taken).
This prescription consists of herbs belonging to the Foot-Yangming Stomach Meridian and Foot-Jueyin Liver Meridian. "Stomach Wind" refers to a state where Stomach Qi is deficient and wind pathogenic factors invade due to this weakness. Wind belongs to Liver Wood, which can overcome Spleen Earth; therefore, Ren Shen, Bai Zhu, and Fu Ling are used to tonify Spleen Qi and benefit Wei Qi (Defensive Qi); Dang Gui and Chuan Xiong nourish Liver Blood and harmonize Ying Qi (Nutritive Qi); Shao Yao drains Liver Qi thereby harmonizing the Spleen and Stomach; Rou Gui (Cinnamon Bark) disperses wind and pacifies Wood (Wood withers when encountering Cinnamon, akin to driving a nail into the root, killing the tree. Furthermore, pungent flavors disperse wind; thus, it can stop diarrhea and treat wind-dampness. It is also said: Bai Zhu and Fu Ling strengthen the Spleen and eliminate dampness, while Chuan Xiong and Rou Gui enter the blood level to drive out wind. *Yu Ji Wei Yi* states: Although this formula is named for treating wind, it does not directly treat wind, but rather treats wind by tonifying the healthy Qi).
Li Dongyuan's Stomach Wind Formula: Sheng Ma (Cimicifugae Rhizoma), Bai Zhi (Angelicae Dahuricae Radix, 1 qian 2 fen), Ma Huang (Ephedrae Herba, without removing joints), Ge Gen (Puerariae Lobatae Radix, 1 qian), Chai Hu (Bupleuri Radix), Qiang Huo (Notopterygii Rhizoma et Radix), Xi Xin (not explicitly listed but implied contextually or missing in source text segment, assuming standard composition if present, but strictly following text: Gao Ben (Ligustici Wallichii Rhizoma), Cang Zhu (Atractylodis Rhizoma), Man Jing Zi (Vittaginis Fructus), Cao Dou Kou (Cardamomi Fructus Rotundus), Huang Bo (Phellodendri Cortex), Dang Gui (Angelicae Sinensis Radix), Zhi Gan Cao (Glycyrrhizae Radix et Rhizoma Preparata with honey, each 5 fen). Add Sheng Jiang (Zingiberis Rhizoma Recens) and Da Zao (Jujubae Fructus) and decoct. It also treats Stomach Wind syndrome (Yu Jiayan says: Why does wind entering the Stomach result in the ability to eat? Generally, wind generates heat, consistent with the principle in *Nei Jing* that Bi syndrome transforms into Xiao Zhong (consumptive thirst). This formula only removes wind without clearing heat, because heat will inevitably resolve along with the wind. He further adds: One must add cold and sweet herbs such as Zhu Li (Bambusa Textilis Caulis Succus), Hua Fen (Trichosanthis Radix), Shi Gao (Gypsum Fibrosum), Wei Rui (Polygonati Odorati Rhizoma), Sheng Di Huang (Rehmanniae Radix), and Li Zhi (Pyrus Sinkiangensis Juice), combined with Sheng Ma, Ge Gen, and Gan Cao as the formulation. Someone asks: These two formulas differ in being tonifying versus dispersing, yet they treat the same syndrome. Why? Yu Jiayan replies: According to *Nei Jing*, "Wind becomes cold and heat," meaning wind enters the Stomach and酿 (ferments/creates) an imbalance between Ying and Wei Qi. This formula is one that drives Stomach wind to resolve from the exterior. However, if chronic wind leads to sundry diarrhea, the wind has entered the interior. In that case, Ren Shen should be the Sovereign herb, Gui Zhi and Bai Zhu the Ministers, and Fu Ling and Gan Cao the Assistants and Couriers, to dispel wind from within. This represents the balance between treating the exterior and interior. *Nei Jing*...)
