肺在五行中对应金。在秋季最为旺盛。其脉象像羽毛一样轻浮。其外在表现反映在鼻子。其声音表现为哭。其气味为腥。其味道为辛。其分泌液为涕。其滋养皮毛。其内藏气。其面色为白。其神志为魄。手太阴肺经是其经脉。与大肠相表里配合。大肠作为腑，主司体表；肺作为脏，主司体内。肺气过盛称为气有余，会导致喘咳、气逆上冲、肩背部疼痛、出汗，以及尻部、阴部、大腿、膝盖、小腿和足部都疼痛。这就是肺气实证。此时应当采用泻法治疗。肺气不足，则会出现气短、呼吸浅促（无法深长呼吸）、耳聋、咽喉干燥。这就是肺气虚证。此时应当采用补法治疗。如果四季中病在肺，痊愈的时间应在冬季。如果冬季不愈，病情加重会在夏季。如果夏季不死，病情会维持于长夏（夏末秋初）。到了秋季就会好转。如果在天干日中，痊愈的日子是壬日和癸日（属水）。如果壬癸日不愈，病情加重会在丙日和丁日（属火）。如果丙丁日不死，病情会维持于戊日和己日（属土）。到了庚辛日（属金）就会好转。禁忌穿寒凉的衣服和吃寒凉的食物。在一天之中，傍晚时症状缓解，半夜时安静，中午时症状加重。肺的特性是喜欢收敛，应赶快食用酸味食物来收敛它，用辛味食物来发散它。
肺部脉象在右手关前寸口处可以诊察到。正常的肺脉微短、涩而像羽毛一样轻浮。秋季脉象以胃气为本底。患肺病的脉象来时，上下感觉如同触摸鸡的羽毛，这叫做患肺病。面色白，身体只觉寒冷而无发热，时常想咳嗽，脉象微迟，这是可治之症。秋季金旺肺亦旺，脉象浮涩而短，这叫平脉（正常脉象）。反而得到浮大洪大的脉象，这是心火乘袭肺金，即火克金，属于大逆之症，难以治愈。反而得到沉濡而滑的脉象，这是肾水乘袭肺金，即子乘母，虽不治也能自愈。反而得到缓大而长的脉象，这是脾土乘袭肺金，即母归子，虽然生病也应当痊愈。反而得到弦而长的脉象，这是肝木乘袭肺金，即木凌金，属于轻微邪气，虽然生病也应当痊愈。肺脉来时，泛泛轻轻，如同微风吹拂鸟背上的羽毛，一呼一吸脉动两次为平脉。三次为离经（异常脉），四次为夺精（精气耗损），五次为死脉，六次为命尽。肺脉来时，如同物体漂浮水面，又像风吹羽毛，这叫肺死脉。秋季脉象微带毛象且有胃气为平脉。胃气少而毛象多为肺病。只有毛象而没有胃气为死脉。毛象中带有弦象表示春季有病。弦象明显表示现在就有病。真正的肺死脉到来时，脉体大而虚，像羽毛刺入人的皮肤那样锐利且无根，面色青白无光泽，毛发枯折，这就预示死亡。
The Lung corresponds to Metal in the Five Elements. It is prosperous in Autumn. Its pulse is light and floating like a feather. Its external manifestation reflects on the nose. Its sound is crying. Its odor is fishy. Its taste is pungent. Its fluid is nasal discharge. It nourishes the skin and hair. It stores Qi. Its complexion is white. Its spirit is Po (Corporeal Soul). The Hand-Taiyin Lung Meridian is its meridian. It is interiorly-exteriorly related with the Large Intestine. The Large Intestine, as a Fu organ, governs the exterior; the Lung, as a Zang organ, governs the interior. Excess Lung Qi is called "excess of Qi," leading to symptoms such as wheezing, coughing, rebellious Qi ascending, shoulder and back pain, sweating, and pain in the sacrum, yin region, thighs, knees, shins, and feet. This is excess syndrome of Lung Qi, and it should be treated with draining methods. Deficiency of Lung Qi leads to shortness of breath, inability to take deep breaths, deafness, and dry throat. This is deficiency syndrome of Lung Qi, and it should be treated with tonifying methods. If the disease is in the Lung during the four seasons, recovery occurs in Winter. If not recovered in Winter, exacerbation occurs in Summer. If death does not occur in Summer, the condition persists in Late Summer. Recovery begins in Autumn. Regarding Heavenly Stems, recovery occurs on Ren and Gui days (Water). If not recovered on Ren/Gui, exacerbation occurs on Bing and Ding days (Fire). If death does not occur on Bing/Ding, the condition persists on Wu and Ji days (Earth). Recovery begins on Geng and Xin days (Metal). Cold clothing and cold food/drink are contraindicated. In a day, symptoms alleviate at dusk, are quiet at midnight, and worsen at noon. The Lung desires consolidation; quickly consume sour foods to consolidate it, and pungent foods to disperse it.
The Lung pulse can be palpated at the Cun Kou position before the Guan position on the right hand. A normal Lung pulse is slightly short, choppy, and light/floating like a feather. In Autumn, the pulse must have Stomach Qi as its foundation. When the Lung is diseased, the pulse feels like touching a chicken feather from top to bottom; this is called Lung disease. With a white complexion, body feeling only cold without fever, frequent desire to cough, and a slightly slow pulse, it is treatable. In Autumn, when Metal is prosperous and the Lung is strong, a floating, choppy, and short pulse is considered a normal pulse (Ping Mai). Conversely, obtaining a large, floating, and surging pulse indicates Heart Fire overacting on Lung Metal (Fire overcoming Metal), which is a major reversal and difficult to treat. Conversely, obtaining a deep, soft, and slippery pulse indicates Kidney Water overacting on Lung Metal (Child overacting on Mother); although ill, it will heal spontaneously. Conversely, obtaining a moderate, large, and long pulse indicates Spleen Earth overacting on Lung Metal (Mother returning to Child); although ill, it should recover. Conversely, obtaining a wiry and long pulse indicates Liver Wood overacting on Lung Metal (Wood suppressing Metal), which is a minor pathogenic factor; although ill, it should recover. The Lung pulse comes lightly and gently, like a breeze blowing feathers on a bird's back. Two beats per respiration cycle indicate normality. Three beats indicate deviation from the standard (Li Jing). Four beats indicate depletion of essence (Duo Jing). Five beats indicate death. Six beats indicate end of life. When the Lung pulse comes like a floating object or wind-blown feathers, it is a dying Lung pulse. In Autumn, a pulse slightly showing the "feather" quality with Stomach Qi is normal. Less Stomach Qi and more "feather" quality indicates Lung disease. Only "feather" quality without Stomach Qi indicates death. "Feather" quality with "wiry" quality indicates Spring disease. Strong "wiry" quality indicates current disease. When the true dying Lung pulse arrives, it is large and empty, sharp like feathers piercing human skin, with a cyan-white lusterless complexion, and brittle hair, indicating impending death.
