天地之气交融，万物因此化育醇厚。男女交合精气，万物由此化生繁衍。在五官之中，鼻子最先形成；在五脏之中，精气最先成就。精气是身体的根本，头部是五体（头、手、足）中的尊位。因此，雷公向黄帝请教大道，黄帝传授医经。五色诊断唯独以明堂（鼻部）为决断依据，四诊（望、闻、问、切）首先观察天牝（鼻孔/鼻子）。大概因为鼻子，是形体生成的开始，也是气息出入的门户。在呼吸之间，与天地相通，贯通经络，五脏六腑的气血没有不达到的，四肢百骸没有不周遍的。划分其部位，就是脏腑六部的提纲；辨别其气色，就是阴阳十法的提纲。其相乘（五行相克过度）的道理，结合部位可以推断；其相应的道理，结合气色可以推断。肝对应青色，心对应赤色，脾对应黄色，肺对应白色，肾对应黑色。至于声音、气味、情志、脉象和病证，也没有不可以推断的。所有的望诊方法，都应当按比例相互参照。《金匮要略》说：鼻头颜色发青，腹中疼痛，如果伴有寒冷征象则预后不良（死）；鼻头颜色微黑，是有水气（水肿或痰饮）；颜色发黄，胸上有寒；颜色苍白，是失血的表现；如果微红且不在相应季节出现，则预后不良（死）。这应当结合四季气候来参考，用阴阳十法来辨别。只是颜色虽然应当辨别，形态也应当区分。望诊的方法，又有提纲可循。大概鼻子是肺的外合器官。鼻子大的，脏气有余；鼻子小的，脏气不足。肿胀隆起的，邪气盛；凹陷下陷的，正气衰。鼻翼煽动的，肺气虚；仰面呼吸的，肺气实。鼻子干枯槁败的，是寒热错杂的证候；鼻子腐蚀溃烂的，是疳疮的形态；鼻窍干燥的，是阳明经的病；鼻柱崩坏的，是麻风病的败症；鼻下红肿像疮疡的，是腹中有虫的疳病；流浊涕的，是外受风热；流清涕的，是外感风寒；鼻渊（慢性鼻窦炎），是脑中热，所以鼻涕下渗；鼻衄（鼻出血），是阳络受伤，所以血液外溢；鼻内生息肉称为“䶦”（注：原文此处可能有缺字或异体字，通常指鼻息肉）；鼻生粉刺称为“皶”（注：原文此处可能有缺字或异体字，通常指酒渣鼻）。这些都是鼻形望诊的方法。分析来说，综合来看，观察五官，参合四诊，变化就在其中了。至于骨部隆起的长寿，骨部凹陷的夭折。所以鼻准（鼻尖）贵在丰隆饱满。其他如气息的粗细、呼吸的快慢、打喷嚏的有无、鼻窍的通塞，应当在各个门类中详细论述，容后续续述。
The Qi of Heaven and Earth blends and interacts, causing all things to mature profoundly. The essence of men and women combines, giving birth to all living things. Among the five sense organs, the nose forms first; among the five Zang organs, Jing (Essence) is perfected first. Essence is the root of the entire body, and the head is the most honorable part of the five physical structures (Head, Hands, Feet). Therefore, Lei Gong asked about the Great Dao, and Huang Di transmitted the classics. The diagnosis of the Five Colors relies solely on the Ming Tang (Nasal Bridge/Nose), and the Four Diagnostic Methods (Inspection, Auscultation/Olfaction, Inquiry, Palpation) begin by observing Tian Pin (Nostrils/Nose). This is because the nose is the beginning of form and the portal for Qi. Through breathing, it connects with Heaven and Earth and penetrates the meridians. The Qi of the Five Zang and Six Fu organs reaches nowhere without being attained, and the four limbs and hundred bones are nowhere without being pervaded. By dividing its regions, one obtains the outline of the six departments of the Zang and Fu organs; by distinguishing its Qi and color, one obtains the outline of the Ten Methods of Yin and Yang. The principle of mutual overcoming (Wu Xing Overcoming) can be deduced by combining it with regions; the principle of correspondence can be deduced by combining it with Qi and color. The Liver corresponds to Green, the Heart to Red, the Spleen to Yellow, the Lung to White, and the Kidney to Black. As for sounds, odors, emotions, pulse conditions, and diseases, there is nothing that cannot be deduced. All inspection methods should refer to each other proportionally. *Jin Gui Yao Lue* states: "If the tip of the nose is green and there is abdominal pain, if it is cold, death ensues. If the tip of the nose is slightly black, there is water qi (fluid retention). If yellow, there is cold in the chest. If white, there is loss of blood. If slightly red and not in season, death ensues." Thus, one should refer to the four seasons and distinguish using the ten methods. However, although colors must be distinguished, forms must also be differentiated. There is an outline for inspection methods. Generally, the nose is the external union of the Lung. A large nose indicates excess Zang Qi; a small nose indicates deficient Zang Qi. Swelling indicates abundant pathogenic Qi; depression indicates depleted healthy Qi. Flaring nostrils indicate Lung deficiency;仰息 (breathing with the head tilted back) indicates Lung excess. A withered and dry nose indicates mixed cold and heat syndromes; erosion and ulceration of the nose indicate the manifestation of Gan Chuang (Gangrenous sores); dry nasal orifices indicate disease of the Yangming Meridian; collapse of the nasal bridge indicates the deteriorating stage of Li Feng (Leprosy); redness and swelling under the nose resembling sores indicate intestinal parasites (Gan disease); turbid discharge indicates external wind-heat; clear discharge indicates external wind-cold; Bi Yuan (Nasal Sinusitis) indicates heat in the brain, causing dripping mucus; Bi Nu (Epistaxis) indicates injury to Yang collaterals, causing external bleeding; flesh growth in the nose is called [Ci]; acne-like bumps on the nose are called [Za]. These are all methods of inspecting nasal form. Analyzed separately and viewed together, by observing the five sense organs and referring to the four diagnostic methods, changes are contained within. Regarding bone structure, protrusion indicates longevity, while depression indicates premature death. Therefore, the Nose Tip (Bi Zhun) is prized for being full and prominent. Other aspects such as the thickness of Qi, the speed of respiration, the presence or absence of sneezing, and the patency or obstruction of orifices will be detailed in respective sections and continued later.
