黄帝问道：头部和面部与身体其他部位相比，虽然都归属于骨骼、连接着筋脉、共同拥有血液，并合于气机运行。天气寒冷时变得凛冽，地气寒冷时结成冰凌。当突然遭遇严寒时，有时会出现手足懈怠无力的情况，然而为什么面部却不需要衣物保暖呢？
岐伯回答说：十二经脉以及三百六十五络脉，它们的气血都向上汇聚于面部并通达各个孔窍。其中精纯的阳气上行至眼睛而形成视觉；别行之气上行至耳朵而形成听觉；宗气上行出于鼻腔而形成嗅觉；浊气从胃中出来，经过嘴唇和舌头而形成味觉。这些气中的津液，也都向上熏蒸于面部，加上面部皮肤厚实、肌肉坚实，所以极寒或极热的气候都不能伤害它。
又说：头部是诸阳经交汇的地方。既然所有阳经的脉气都上达头部，那么面部的寒热变化，主要取决于足阳明胃经的虚实状况。本经（足阳明胃经）多血多气，如果木气（肝气）亢盛则导致风热上行，可能出现鼻部和面部红紫，伴有风刺（粉刺）、瘾疹（荨麻疹）等症状同时发作。
面部的浮肿，有两种不同的区别。肿胀属于肝风内动，若兼有胃火实证，风火之气上炎，会导致面部红肿且发热，按压时会感到疼痛。这是邪气有余的表现，脉象必定躁急紧实，应当使用防风通圣散之类的方剂来疏散并泻下邪气。浮肿属于脾土虚弱，肺金不足，因脾胃受损、劳役过度，导致肺气失去调节，有时出现喘息症状，这是正气不足的表现，脉象必定虚浮无力。应当使用利水实脾汤之类的方剂来引导并利水消肿。

The Yellow Emperor asked: The head and face, compared to the rest of the body, are connected to bones and tendons, share blood, and integrate with Qi. When heaven is cold, it becomes biting; when earth is cold, ice forms. In sudden severe cold, sometimes the limbs become flaccid and weak, yet why does the face not require clothing for warmth?
Qibo replied: The twelve primary meridians and the three hundred and sixty-five collaterals all direct their Qi and Blood upward to the face and through its orifices. The refined Yang Qi ascends to the eyes to form vision; the branch Qi ascends to the ears to form hearing; the Zong Qi (Gathering Qi) ascends out of the nose to form smell; the turbid Qi emerges from the Stomach, passing through the lips and tongue to form taste. The fluids and essence of these Qi all steam upward to bathe the face. Furthermore, the facial skin is thick and the flesh firm, so extreme cold or extreme heat cannot overcome it.
It is also said: The head is the convergence point of all Yang meridians. Since all Yang meridians ascend to the head, the coldness or heat of the face depends on the deficiency or excess of the Foot-Yangming Stomach Meridian. This meridian is abundant in both Blood and Qi. If Wood Qi (Liver Qi) becomes excessive, wind-heat ascends, potentially causing redness and purpleness of the face and nose, accompanied by acneiform eruptions and urticaria.
Facial edema has two distinct types. Swelling associated with Liver Wind, combined with Stomach Fire excess, causes wind-fire to flare upward, resulting in red, swollen, hot areas that are painful upon pressure. This indicates an excess of pathogenic factors, and the pulse will be restless, rapid, tight, and solid. One should use formulas such as Fangfeng Tongsheng San (Saposhnikovia Decoction to Unblock the Heroic) to disperse and purge the pathogen. Edema associated with Spleen Earth deficiency and Lung Metal insufficiency, often due to Spleen damage from overwork, leading to loss of Lung Qi regulation and occasional panting, indicates a deficiency of righteous Qi. The pulse will be deficient, floating, and forceless. One should use formulas such as Lishui Shipi Tang (Water-Draining Spleen-Strengthening Decoction) to guide and promote diuresis.
