肾乘心，心先病，肾为应，色皆如是。男子色（以黑色言。）在于面王，为首腹痛，（首腹，大腹。）下为
卵痛，其圜直为茎痛，高为本，下为首，狐疝 阴之属也。女子色在于面王，为膀胱子处之病，散为痛，抟
为聚，方圆左右，各如其色形。其随而下至胝（谓其色连人中。）为淫。（谓伤中淋露也。）有润如
膏状，（谓鼻准色黑光浮而明如涂膏者。）为暴食不洁。（暴食即出不洁，仓
公所谓迥风。）其色赤大如榆荚，在面王为不月。（《内经》。）
鼻头色青，腹中痛，苦冷者，死。鼻头色微黑者，有水气；色黄者，胸上有寒；色白者，亡血也。设
微赤非时者死。其目正圆者，痉不治。（此承上句说下，非专论目也。）又色青为痛，
色黑为劳，色赤为风，色黄者便难，色鲜明者有留饮。（末五句非专论鼻色。仲景。）
黄色见于鼻，干燥如土偶之形，为脾气绝，主死。若如
桂花，杂以黑晕，只是脾病，饮食不快，四肢怠惰，妻外家之累。（见前。）
鼻头色黑而枯燥者，房劳；黑黄而亮者，有瘀血；赤为
肺热。鼻孔干燥，目瞑，漱水不咽者，欲衄也。鼻孔黑如烟
煤而燥者，阳毒也。鼻孔煽张者，肺绝也。但煤黑而不煽不喘者，燥热结于大肠也。黄黑枯槁，为脾火津涸。
大便燥结，鼻塞浊涕者，风热也。鼻孔冷滑而黑者，阴毒也。鼻头汗出如珠，为心脾痛极。（石顽《医通》。）

When Kidney pathogenic factors invade the Heart, the Heart becomes diseased first, and the Kidney responds subsequently; such are the manifestations of facial color changes. In men, if black color appears on the Mianwang (tip of the nose), it indicates abdominal pain in the great abdomen; lower down, it manifests as testicular pain. If the blackness is circular and straight downward, it indicates penile pain; the elevated part corresponds to the root, and the depressed part to the head, which belongs to the category of Huhan (Fox Hernia) affecting the yin organs. In women, if black color appears on the Mianwang, it indicates diseases of the Bladder and Zi Chu (uterus); a scattered color indicates pain, while a consolidated color indicates accumulation (Ju). Regardless of whether the shape is round, square, left, or right, it corresponds to the form of the black color. If the blackness extends downward connecting to the Renzhong (philtrum), it indicates injury to the middle jiao causing damp-heat discharge (Linlu). If the tip of the nose is black, lustrous, floating, and bright like applied ointment, it indicates gluttony with unclean food (i.e., "Jiongfeng," mentioned by Cang Gong). If the red color is large like elm seeds and appears on the Mianwang, it indicates amenorrhea (from *Neijing*).
If the nose tip is green, it indicates abdominal pain; if accompanied by aversion to cold, it is a fatal condition. If the nose tip is slightly black, it indicates water qi retention; if yellow, it indicates cold in the chest; if white, it indicates loss of blood. If a slight redness appears out of season, it is a fatal condition. If the eyes are fixed straight open, it indicates Jing disease (spasm), which is difficult to treat. (This sentence follows up on the previous context regarding severe conditions, not specifically discussing eye diseases.) Furthermore, green color indicates pain, black indicates exhaustion/labor, red indicates wind, yellow indicates difficulty in defecation, and bright/shiny color indicates retained fluid (Liu Yin). (The last five sentences do not specifically discuss nose color; from Zhang Zhongjing.)
If yellow color appears on the nose, dry and lifeless like a clay idol, it indicates the extinction of Spleen Qi, which is fatal. If the color resembles osmanthus flowers mixed with black halos, it is merely a Spleen disease, manifesting as poor appetite, lethargy of the four limbs, and burdens from family matters. (See previous text.)
If the nose tip is black and dry, it indicates sexual exhaustion; if black-yellow and shiny, it indicates blood stasis; if red, it indicates Lung heat. Dry nostrils, closed eyes, rinsing mouth but not swallowing water indicate impending epistaxis. Nostrils black like soot and dry indicate Yang Du (Yang Toxin). Flaring nostrils indicate Lung Qi extinction. Blackness without flaring or panting indicates dry-heat binding in the Large Intestine. Yellow-black and withered indicates Spleen fire exhausting body fluids. Dry stool, nasal congestion, and turbid discharge indicate Wind-Heat. Cold, slippery, and black nostrils indicate Yin Du (Yin Toxin). Sweat beads forming on the nose tip indicate extreme pain of the Heart and Spleen. (From Shi Wan's *YiTong*.)
