风缓证，是指风邪深入体内，导致手足松弛无力的病证。大凡人的四肢百脉，遇到寒邪就会痉挛拘急，遇到热邪就会柔顺舒缓。病在阳分，经气运行迟缓而关节弛纵；病在阴分，经气运行急促而关节收敛，这是事物发展的常理。然而脾主肌肉和四肢，胃为水谷之海，负责流布水谷的精微之气，周身滋养。如果脾胃虚弱，肢体失去滋养，于是风邪乘虚而入，由腠理进入肌肉，再由肌肉传入脾胃，怎么能不导致肢体松弛废用呢？如果说驱风的方剂与助胃的方剂不同，这也取决于医者如何灵活运用罢了。我听说人的身体，筋骨强健则身体壮实，肝主筋，肾主骨，如果肝肾气虚，风邪侵袭，也会出现肢体缓弱的证候，那么在这种情况下，应当先疏散风邪然后再补益，对此更应加以注意。
排风汤、续命汤（方剂见风类章节）加入制半夏、鸡心大小的槟榔，增加生姜煎煮，先用此方疏散风毒邪气。苏合香丸 用沸水冲泡，用生姜汁调开，吞服真料白丸子二十丸，每日两次，治疗手足风缓。或者交替使用白丸子、安肾丸，饭前服用。（方剂见咳嗽门、身疼门、水饮门。）

其他用药，在风类章节中已有详细说明。
Fenghuan (Flaccidity due to Wind) refers to a condition where wind pathogen penetrates deeply into the body, causing flaccidity and weakness of the hands and feet. Generally, the four limbs and hundred vessels of a person will become spasmodic and tight when encountering cold, and become soft and relaxed when encountering heat. When the disease is in the Yang aspect, the Qi of the meridians flows slowly, leading to laxity of the joints; when the disease is in the Yin aspect, the Qi of the meridians flows rapidly, leading to contraction of the joints. This is the normal law of nature. However, the Spleen governs the muscles and four limbs, and the Stomach is the sea of water and grain, responsible for distributing the Qi of water and grain to nourish the whole body. If the Spleen and Stomach are deficient, the limbs lose their nourishment. Consequently, wind pathogen attacks the deficiency, entering from the Couli (pores) into the muscles, and then from the muscles into the Spleen and Stomach. How can it not lead to flaccidity and disability? Some may say that wind-dispelling formulas differ from stomach-strengthening formulas, but this depends on how flexibly the practitioner applies them. I have heard that the strength of the human body relies on the sinews and bones; the Liver governs the sinews, and the Kidney governs the bones. If the Qi of the Liver and Kidney is deficient and wind pathogen invades, there will also be symptoms of limb flaccidity and weakness. In such cases, one should first disperse the wind and then tonify, paying special attention to this approach.

Use this first to disperse wind-toxin and evil qi. Suhexiang Wan (Styrax Pill): Soak in boiling water, mix with Jiangzhi (Ginger Juice), and swallow 20 pills of Zhenliao Baiwanzi (True Material White Pills), twice daily, treating flaccidity of hands and feet.
