男子取左手，女子取右手。手中指第二节内侧两条横纹之间的距离为一寸。用稻秆心来测量。如果用薄竹片测量则容易折断。用蜡纸测量则粘手不便。用绳子测量则有伸缩性导致不准。用稻秆心测量则容易获得且准确。
肺重三斤三两。有六叶两片耳状突起。总共八叶。向下垂挂如伞盖状。附着于脊柱的第三椎骨处。中间有二十四个空隙，排列成行。（每一方寸为一两。现在按照权衡度量标准，起源于黄钟律管。古代的一两，相当于现在的四钱多一点。）
西方对应白色。气机内通于肺。开窍于鼻。精气藏于肺。所以病变表现在背部。其味为辛。其五行属性为金。其对应的家畜为马。其对应的谷物为黍（注：原文此处似有缺漏或版本差异，通常五谷中金对应麦，但古籍有时指代不同，依原文“其谷”后接下文逻辑，此处仅译出可见文字）。
西方产生燥气。燥气产生金。金产生辛味。辛味产生肺气。肺气滋养皮毛。皮毛之气归于肾。肺主管鼻。在天为燥气。在地为...（原文此处断句较碎，结合上下文补全语义）...味为辛。在情志为忧。忧伤肺。喜能胜忧。热邪伤害皮毛。寒能胜热。辛味伤害皮毛。苦味能胜辛味。《素问》记载：膻中穴，是臣使之官，喜乐之情由此发出。
肺，是气的根本，魄所居之处。其荣华表现于毛发，其充养部位在皮肤。属于阳中之太阴，与秋气相通。《素问》记载：肺合皮毛，其荣在毛。肺的主宰者是心。肺气通于鼻。鼻功能调和，就能辨别香臭。《难经》记载：肺气虚，就会使人梦见白色物体，梦见被人斩杀、血迹斑斑。如果在秋季三个月发病，症状会加重。
肺的颜色应白，像鹅毛一样润泽，不像盐那样枯白。《素问》记载：肺色白象金。金遇水下沉，肺遇水为何上浮？因为肺并非纯金之体，而是辛商（音shāng，指肺金之柔），是丙火的柔顺表现。大言阴与...（原文此处可能有脱文或排版错误，依义理推测涉及阴阳转化）...再次下沉，是因为辛应当归庚（金之刚）。物极必反。肺气衰竭，则皮毛焦枯。肺气运行于皮毛，气不能荣养，则皮毛焦枯。皮毛焦枯，则津液流失。津液流失，则皮节受伤。皮节受伤，则皮肤干枯、毛发折断。毛发折断者，说明毛先死。在丙日病情加重，在丁日死亡。《难经》记载。
For males, use the left hand; for females, the right hand. The distance between the two transverse creases on the inner side of the second phalanx (middle joint) of the middle finger constitutes one Cun (同身寸). Measure using the pith of a rice straw. If thin bamboo is used, it may easily break. If waxed paper is used, it sticks to the hand and is inconvenient. If a string is used, its elasticity leads to inaccuracy. Using rice straw pith is readily available and accurate.
The Lung weighs three jin and three liang. It has six lobes and two ear-like appendages, totaling eight lobes. They hang downwards like a canopy, attached to the third thoracic vertebra of the spine. In the center, there are twenty-four hollow spaces arranged in rows. (One square Cun equals one Liang. According to current standards of weight and measure, originating from the Huangzhong pitch pipe, one ancient Liang is equivalent to slightly more than four Qian in modern terms.)
The West corresponds to the color white. Its Qi internally connects with the Lung. It opens into the nose. Essence is stored in the Lung. Therefore, diseases manifest in the back. Its flavor is Pungent (Xin). Its elemental category is Metal. Its associated domestic animal is the Horse. Its associated grain is Shu (Millet).
The West generates Dryness. Dryness generates Metal. Metal generates Pungency. Pungency generates Lung Qi. Lung Qi nourishes the Skin and Hair. The Qi of Skin and Hair returns to the Kidney. The Lung governs the Nose. In Heaven, it is Dryness. On Earth... its flavor is Pungent. In emotions, it is Sorrow. Sorrow damages the Lung. Joy overcomes Sorrow. Heat pathogenic factors damage the Skin and Hair. Cold overcomes Heat. Pungency damages the Skin and Hair. Bitterness overcomes Pungency. As recorded in *Su Wen* (Basic Questions): The Danzhong (Constrictor Vessel/Pericardium region) is the official of the minister and envoy, from which Joy and Happiness emerge.
The Lung is the root of Qi and the residence of Po (Corporeal Soul). Its luster manifests in the hair, and its substance fills the skin. It belongs to Yang within Yin (Taiyin), and communicates with the Qi of Autumn. As recorded in *Su Wen*: The Lung combines with the Skin and Hair, and its luster is in the hair. The Lung is controlled by the Heart. Lung Qi connects to the nose. When the nose functions harmoniously, one can distinguish odors. As recorded in *Nan Jing* (Classic of Difficult Issues): When Lung Qi is deficient, one dreams of white objects or sees people being slaughtered with bloodstains. If this occurs during the three months of Autumn, the condition worsens.
The color of the Lung should be white, resembling goose feathers [lustrous], not salt [dull]. As recorded in *Su Wen*: The white color of the Lung resembles Metal. Metal sinks when it meets water; why does the Lung float when it meets water? Because the Lung is not pure Metal, but rather Xin-Shang (a term referring to the soft aspect of Metal/Golden element), the soft expression of Bing Fire. ...When it sinks again, Xin should return to Geng (the hard aspect of Metal). Things turn into their opposites when they reach the extreme. When Lung Qi perishes, the Skin and Hair become scorched and dry. Lung Qi circulates through the Skin and Hair; if Qi fails to nourish, the Skin and Hair become scorched and dry. Scorched and dry Skin and Hair lead to the loss of Body Fluids. Loss of Body Fluids injures the joints of the skin. Injury to the skin joints causes the skin to wither and hair to break. When hair breaks, it indicates that the hair dies first. The condition deteriorates on Bing days and death occurs on Ding days. As recorded in *Nan Jing*.
