《灵枢》曰∶手面与身形也，天寒则裂地凌冰，或手足懈堕，然而其面不衣，何
也？曰∶十二经脉三百六十五络，其血气皆上于面而走空窍，其精，阳气上走于目
而为睛，其别，气走于耳而为听，其宗气，
上出于鼻而为臭，其浊气出于胃，走唇舌而为味，其气之津液，皆上熏于面，而皮
又浓，其肉坚，故天热甚寒，不能胜之也。
东垣曰∶饮食不节则胃病，胃病则气短精神少，而生大热，有时而火上独燎其
面，盖阳明经多气多血，又兼挟风热上行，诸阳皆会于头面，故令面热如醉。治宜先
散其风热，或以调胃承气汤加黄连、犀角，疏下两三行，彻其本热，散其风热，以升
麻汤加黄连主之。
冯鲁瞻曰∶手足六阳之经，皆上至于头，而惟阳明胃脉，起鼻交 中，入上齿
中，挟口环唇，循颊车上耳前，过客主人，故人之面部，阳明之所属也。其或胃中有
热，有郁火，则面热，升麻汤加黄连；若风热内甚而上攻，令人面目浮肿，或面鼻
紫色，或风刺瘾疹，随证治之。

《灵枢》说：手部和面部的情况与身形有关。天气寒冷时，大地开裂，冰凌凝结，甚至手足懈怠下垂，然而面部却不穿衣服保暖，为什么呢？回答说：十二经脉和三百六十五络穴，它们的血气都上行于面部并通达各个孔窍。其中精气、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；宗气上行出于鼻子而形成嗅觉；浊气出于胃，上行至唇舌而形成味觉。这些气的津液，都向上熏蒸于面部，而且面部皮肤又厚，肌肉坚实，所以即使天气极热或极寒，也不能伤害它。
李东垣说：饮食不节制就会损伤胃，胃受损则气短、精神减少，从而产生大热。有时只有火气单独燃烧在面部。这是因为阳明经多气多血，又兼挟风热上行，所有的阳经都汇聚于头面，所以导致面部发热如同醉酒一般。治疗应当先疏散风热，或者使用调胃承气汤加入黄连、犀角，疏通大便两三次，清除根本的热邪，疏散风热，以升麻汤加入黄连为主方治疗。
冯鲁瞻说：手足六条阳经，都上行至头部，而唯独阳明胃经，起于鼻旁交于目内眦，进入上齿中，环绕口唇，沿颊车穴上行至耳前，经过客主人穴（上关穴）。所以人的面部，归属于阳明经管辖。如果胃中有热，有郁积的火气，就会导致面部发热，可用升麻汤加入黄连；如果是风热内盛而上攻，导致人面目浮肿，或者面部鼻子呈紫色，或者出现风刺瘾疹，应根据症状进行治疗。
All carbuncles, sores, ulcers, and toxic swellings belonging to the zygomatic region, cheeks, parotid area, chin, and nose are compiled in this section for easy reference and treatment.
Redness of the zygomatic and cheek areas appearing in the afternoon indicates rising deficiency fire (Xu Huo); it should not be treated as Taiyang Cold Damage (Shang Han).
Red face with a rapid but forceless pulse indicates Hidden Yin Disease (Fu Yin Bing), which is false heat.
Red face with a deep and fine pulse indicates Shaoyin Disease (Shao Yin Bing), characterized by external heat and internal cold, where excess Yin repels Yang outward; warming methods are appropriate, while misusing cooling herbs will lead to death.
Red face with a wiry and rapid pulse indicates Shaoyang Disease (Shao Yang Bing); Xiaochaihu Tang (Minor Bupleurum Decoction) is suitable for harmonizing.
General redness of the entire face indicates that the Yangming exterior syndrome has not yet resolved; muscle-releasing methods are indicated, while purging the interior is contraindicated.
Blue-green color of the face and lips indicates extreme Yin cold.
Blue-green face accompanied by tongue retraction and testicular contraction indicates Yin cold.
Blue-green face accompanied by lower abdominal pain indicates Cold Damage complicated by Kidney deficiency (Jia Yin Shang Han).
Yellowing of the face, eyes, and body accompanied by short and scanty urination indicates Damp-Heat (Shi Re).
Yellowing of the face, eyes, and body accompanied by distension, fullness, hardness, and pain in the lower abdomen with free urination indicates Blood Stasis Cold Damage (Xu Xue Shang Han).
Pale face lacking spirit or accompanied by excessive sweating indicates collapse due to blood loss (Tuo Xue).
Individuals with pale faces should not undergo heavy sweating therapies.
Individuals with dark complexions who develop deficiency patterns during Cold Damage should not receive strong tonification with Ginseng Radix et Rhizoma (Renshen) and Atractylodis Macrocephalae Rhizoma (Baizhu), as their Qi tends to be excess in nature.
The *Ling Shu* states: The condition of the hands and face reflects the state of the body. When heaven is cold, the earth cracks and ice forms, and limbs may become flaccid and drooping, yet the face remains uncovered. Why? It is said that the Twelve Meridians and 365 Luo-collaterals all direct their blood and Qi upward to the face and enter the sensory orifices. The essence and Yang Qi ascend to the eyes to form vision; divergent Qi ascends to the ears to form hearing; Zong Qi (Gathering Qi) emerges from the nose to form smell; turbid Qi originates from the Stomach and ascends to the lips and tongue to form taste. The fluids and Qi of these meridians all steam upward onto the face. Furthermore, the facial skin is thick and the flesh firm, so neither extreme heat nor extreme cold can overcome it.
Li Dongyuan stated: Irregular diet damages the Stomach; Stomach damage leads to shortness of breath and diminished spirit, generating intense heat. Sometimes, fire alone blazes upon the face. This is because the Yangming Meridian is rich in both Qi and Blood, and often carries Wind-Heat upward. Since all Yang meridians converge at the head and face, this causes the face to feel hot as if intoxicated. Treatment should first disperse Wind-Heat, or use Tiaowei Chengqi Tang (Regulate the Stomach and Order the Pills Decoction) added with Coptidis Rhizoma (Huanglian) and Rhinoceros Horn (Xijiao - note: usually substituted with Water Buffalo Horn in modern practice) to induce bowel movements two or three times, clearing the root heat and dispersing Wind-Heat. Alternatively, Shengma Tang (Cimicifugae Decoction) added with Huanglian is the primary formula.
Feng Luzhan stated: The six Yang meridities of the hands and feet all ascend to the head, but specifically the Yangming Stomach Meridian begins beside the nose, crosses at Yingxiang (LI20), enters the upper teeth, surrounds the lips, follows the Jiache point (ST6) up to the front of the ear, passes through Shangguan (ST7), thus governing the human face. If there is heat or stagnant fire in the Stomach, facial heat occurs; Shengma Tang added with Huanglian is used. If Wind-Heat is severe internally and attacks upward, causing swelling of the face and eyes, purple discoloration of the face and nose, or wind-induced prickling and hives, treatment should be based on the specific symptoms.
