凡是眼睛明亮、能够看清事物的，属于可治之证；若眼睛昏花、不能识人，或者眼球向上翻视，或瞪眼直视，或眼球固定不动呈正圆状，或戴眼反折（两眼上视不能转动），或眼睑凹陷的，都属于不治之证。凡是睁着眼睛想要看人的，属于阳证；闭着眼睛不想看人的，属于阴证。凡是眼中感觉模糊不清、眼神不和顺的，是体内热邪炽盛的表现。凡是眼睛疼痛的，属于阳明经的热证；眼睛发红也是热邪炽盛的表现。凡是畏光闭眼的，必将发生鼻衄（鼻出血）。凡是白睛发黄的，将要发生身体发黄（黄疸）的病证。凡是疾病快要痊愈时，会出现目黄消退、鼻尖明亮、山根（鼻梁根部）发亮的征象。
鼻头颜色发青的，腹中疼痛且伴有冷感的，预后不良属死证；颜色微黑的，是有水气病；颜色发黄的，小便困难；颜色白色的，是气虚；颜色发赤的，是肺热；颜色鲜明润泽的，是有留饮（水饮停留）。鼻孔干燥的，属于阳明经的热证，必将发生鼻衄。鼻孔干燥且黑如烟煤状的，是阳毒热邪深重。鼻孔寒冷滑润且黑色的，是阴毒寒邪极盛。呼吸时打鼾嗜睡的，是风温病。鼻塞流浊涕的，是风热病。鼻孔扇张的，是肺风或肺气将绝，属于不治之证。
凡是口唇焦干的，是脾热；焦而红色的，预后良好；焦而黑色的，预后凶险。口唇都红肿的，是热邪炽盛。口唇都青黑的，是寒邪极盛。口苦的，是胆热。口中甜的，是脾热。口燥咽干的，是肾热。舌干口燥且想喝水的，是阳明经的热证。牙关紧闭难以说话的，是痉风病。凡是嘴唇上有疮疡的，是狐虫侵蚀其内脏；下唇有疮疡的，是惑虫侵蚀其肛门。若是嘴唇青紫、舌头卷缩、口角周围发青、环口黧黑、口开不合、气息直出不收、口如鱼口张开、口唇颤动不止、气息无法回返的，都属于不治之证。
凡是耳廓红润的，主生；若耳廓黄、白、黑、青且干枯的，主死。耳廓薄而白的，或薄而黑的，都是肾气败坏的表现。凡是耳聋、耳中疼痛的，都属于少阳经的热证，尚为可治。若是耳聋、舌头卷缩、嘴唇青紫的，这属于厥阴经病证，为难治。
凡是舌色鲜红的，预后良好；青色的是寒证，青而紫的是阴寒证；赤而紫的是阳热证。舌色发黑的，是亢极难治。凡是舌苔白而滑润的，是表有寒邪；又说这是丹田有热而胸中有寒。舌苔黄而干燥口渴的，是热盛。舌苔黑而干燥口渴的，是热甚且亢极。如果不干燥口渴，舌上黑苔且滑润的，是寒证、阴证。舌头卷缩、焦黑且干燥的，是阳毒热极。舌青且苔滑润的，是阴毒冷极。凡是舌体肿胀、舌面干燥裂开、舌生芒刺的，都是热邪炽盛。凡是舌体僵硬、舌强、舌短缩、神志昏乱、语言不清的，属于死证。又是阴阳易病，舌头吐出数寸长的，属于死证。舌是心的窍穴，属火，舌色红的是吉兆，只有黑色是水克火，所以难治。
If the eyes are bright and capable of clear vision, the condition is treatable. If the eyes are dim and unable to recognize people, or if they look upward, stare straight ahead, remain fixed in a round shape, exhibit "dai yan" (eyes fixed upward and unable to move), or if the eyelids are sunken, these are all untreatable conditions. Those who keep their eyes open and wish to see others have a Yang syndrome; those who keep their eyes closed and do not wish to see others have a Yin syndrome. A sensation of blurriness in the eyes and lack of coordination in gaze indicates intense heat within. Eye pain belongs to Heat of the Yangming channel; redness of the eyes also indicates intense heat. Photophobia will inevitably lead to epistaxis (nosebleed). Yellowing of the sclera indicates that jaundice (body yellowing) is about to develop. When a disease is about to resolve, signs include the fading of eye yellowness, brightness of the nasal tip, and luminosity of the shangen (root of the nose).
A bluish color at the nasal tip indicates abdominal pain with cold sensations, which is a fatal prognosis. A slightly black color indicates fluid retention (water qi); a yellow color indicates difficult urination; a white color indicates Qi deficiency; a red color indicates Lung Heat; and a bright, lustrous color indicates retained fluids (liu yin). Dry nostrils belong to Heat of the Yangming channel and will inevitably lead to epistaxis. Dry nostrils that are black like soot indicate severe deep-seated heat from Yang toxicity. Cold, slippery, and black nostrils indicate extreme cold from Yin toxicity. Snoring during sleep indicates Wind-Warmth (Feng Wen); nasal congestion with turbid discharge indicates Wind-Heat. Flaring of the nostrils indicates Lung Wind or impending collapse of Lung Qi, which is untreatable.
Chapped and dry lips indicate Spleen Heat; if chapped but red, the prognosis is good; if chapped and black, it is ominous. Swelling and redness of both lips indicate intense heat. Cyanosis and blackness of both lips indicate extreme cold. Bitter taste in the mouth indicates Gallbladder Heat; a sweet taste indicates Spleen Heat; dry mouth and throat indicate Kidney Heat. Dry tongue and mouth with a desire to drink water indicate Heat of the Yangming channel. Trismus (lockjaw) and difficulty speaking indicate Jing Feng (spasmic wind). Sores on the upper lip indicate Hu Chong (roundworms) eroding the internal organs; sores on the lower lip indicate Huo Chong eroding the anus. If the lips are cyanotic, the tongue is curled, the corners of the mouth are blue, the area around the mouth is dark, the mouth is open with uncontrolled exhalation, the mouth resembles a fish's gape, the lips tremble uncontrollably, and breath does not return, these are all untreatable conditions.
Reddish-pink earlobes indicate life; yellow, white, black, or blue earlobes that are dry and brittle indicate death. Thin and white, or thin and black earlobes both indicate failure of the Kidneys. Deafness and ear pain belong to Heat of the Shaoyang channel and are still treatable. However, deafness accompanied by a curled tongue and cyanotic lips belongs to the Jueyin channel and is difficult to treat.
A fresh red tongue color is auspicious; blue indicates cold; blue-purple indicates Yin cold; red-purple indicates Yang heat. A black tongue is extremely hyperactive and difficult to treat. A white and slippery tongue coating indicates exterior cold; alternatively, this may indicate Heat in the Dantian and Cold in the chest. A yellow and dry coating with thirst indicates excess heat. A black and dry coating with thirst indicates extreme heat and hyperactivity. If there is no thirst, and the black coating is slippery, it indicates Cold and Yin. A curled, scorched-black, and dry tongue indicates extreme heat from Yang toxicity. A blue tongue with a slippery coating indicates extreme cold from Yin toxicity. Tongue swelling, dry cracking, and prickles on the tongue all indicate intense heat. Stiffness, rigidity, shortening of the tongue, confusion of spirit, and unclear speech indicate death. In the case of Yin-Yang transmission disease, a tongue protruding several inches indicates death. The tongue is the orifice of the Heart and belongs to Fire; a red color is auspicious, whereas black indicates Water overcoming Fire, making it difficult to treat.
