治疗风痱（中风后遗症，表现为肢体瘫痪但无疼痛感），症见半身不遂、手足无力、无法行走活动者。长期服用此方，自会显现疗效。
黄耆（蜜炙）六钱 白芍药（酒炒）三钱 桂枝（嫩枝连皮）三钱 生姜（带外皮）三钱 大枣（去核）四枚。水煎服。
【注】《内经》说：虚邪偏侧客居于身体一半，侵入较深者，内居营卫之间，营卫衰败则真气离去，邪气独留，发为偏枯（半身不遂）；邪气浅表者，脉象偏侧疼痛。这说的是虚邪贼风中伤人体。营卫虚弱则邪气侵入深，久留不去发为偏枯、半身不遂；营卫充实则邪气侵入浅，即刻表现为经脉偏侧疼痛，即风痹病。对于八风、五痹之病，若营卫实证，则用续命汤、换骨丹来发散营卫之邪。而风痱、偏枯之病，属于营卫虚证，则应当用此方补益营卫之虚。所以以黄耆为君药以补卫气，桂枝、白芍为臣药以补营血，生姜、大枣为佐药，补益兼通利，以调和营卫。此方是小建中汤的变制，加入黄耆，减去甘草、饴糖，其意在于补益体表（肌表），而不在于补益中焦脾胃。若左半身不遂，则加当归以补血；右半身不遂，则加倍黄耆以补气。手部软弱无力，加倍桂枝；足部软弱无力，加牛膝；筋部软弱无力，加木瓜；骨部软弱无力，加虎骨；元气虚弱，加人参；阳气虚弱，加附子。临证时请医生根据具体情况灵活加减。长期服用，没有不应验的。如果外感风邪盛实，则又应当从羌活愈风汤入手，在补益的同时疏散风邪即可。
Treats Fengfei (post-stroke sequelae characterized by limb paralysis without pain), presenting with hemiplegia, weakness in the hands and feet, and inability to walk or move. Long-term administration will naturally reveal its efficacy.
Huangqi (Astragali Radix, honey-fried) 6 qian, Baishao Yao (Paeoniae Radix Alba, wine-fried) 3 qian, Guizhi (Cinnamomi Ramulus, tender branch with bark) 3 qian, Shengjiang (Zingiberis Rhizoma Recens, with outer skin) 3 qian, Dazao (Jujubae Fructus, pitted) 4 pieces. Decoct in water and take orally.
[Note] The *Classic of Internal Medicine* states: When empty pathogens (Xu Xie) reside on one side of the body, if they penetrate deeply, they lodge within Ying and Wei (Nutritive and Defensive Qi). When Ying and Wei decline, True Qi departs, leaving only the pathogen, resulting in Piangu (hemiplegia); if the pathogen is superficial, there is unilateral meridian pain. This refers to the invasion of empty pathogens and thievish winds. If Ying and Wei are deficient, the pathogen penetrates deeply, lingering for a long time to cause Piangu and hemiplegia; if Ying and Wei are solid, the pathogen penetrates shallowly, immediately causing unilateral meridian pain, which is Wind-Bi disease. For diseases of Eight Winds and Five Bi syndromes, if Ying and Wei are in an excess state, use Xuming Tang or Huangu Dan to disperse the pathogens in Ying and Wei. However, for Fengfei and Piangu, which involve deficiency of Ying and Wei, this decoction should be used to tonify the deficiency of Ying and Wei. Therefore, Huangqi is used as the Sovereign herb to tonify Wei Qi, Guizhi and Baishao as Ministers to tonify Ying Blood, while Shengjiang and Dazao act as Assistants, providing both tonification and unblocking action to harmonize Ying and Wei. This formula is a variation of Xiaojianzhong Tang, adding Huangqi and removing Gancao and Yitang, indicating its intent to tonify the exterior (muscle layer) rather than the Middle Jiao. If the left side is hemiplegic, add Danggui to tonify blood; if the right side is hemiplegic, double the dosage of Huangqi to tonify Qi. For softness/weakness in the hands, double Guizhi; for softness/weakness in the feet, add Niuxi; for softness/weakness in the tendons, add Mugua; for softness/weakness in the bones, add Hugu; for deficiency of Yuan Qi, add Renshen; for deficiency of Yang Qi, add Fuzi. Practitioners should adjust according to clinical presentation. Long-term administration will yield consistent results. If external wind pathogens are excessive, one should instead refer to Qianghuo Yufeng Tang, employing a strategy of tonification combined with dispersion.
