肺象金，旺于秋。其脉如毛而浮，其候鼻，其声哭，其臭腥，其味辛，其液涕，其养皮
毛，其藏气，其色白，其神魄；手太阴其经。与大肠合，大肠为腑主表，肺为脏主里。
肺气盛，为气有余，则病喘咳上气，肩背痛，汗出，尻、阴、股、膝、 、胫、足皆痛
，是为肺气之实也，则宜泻之；肺气不足，则少气不能报息，耳聋，嗌干，是为肺气之虚也
，则宜补之。
于四时∶病在肺，愈在冬；冬不愈，甚于夏；夏不死，持于长夏；起于秋。于日∶愈在
壬癸；壬癸不愈，加于丙丁；丙丁不死，持于戊己；起于庚辛。于时∶下晡慧，夜半静，日
中甚。肺欲收，急食酸以收之，用酸补之，辛泻之。禁寒饮食、寒衣。
肺部，在右手关前寸口是也。平肺脉来，厌厌聂聂，如落榆荚，曰肺平。秋以胃气为本
。秋，肺金王，其脉浮涩而短，是曰平脉也。反得浮大而洪者，是心之乘肺，火之克金，为
大逆，十死不治也；反得沉濡而滑者，是肾之乘肺，子之扶母，病不治自愈；反得缓大而长
阿阿者，是脾之乘肺，母之归子，虽病当愈；反得弦而长者，是肝之乘肺，木之陵金，为微
邪，虽病当愈。肺脉来泛泛而轻，如微风吹鸟背上毛。再至曰平，三至曰离经，
四至曰夺精，五至曰死，六至曰命尽。病肺脉来，上下如循鸡羽，曰肺病。肺病，其色白，
身体但寒无热，时时欲咳，其脉微迟，为可治。死肺脉来，如物之浮，如风吹毛，曰肺死。
秋胃微毛曰平，胃气少毛多曰肺病，但如毛无胃气曰死。毛有弦曰春病，弦甚曰今病。真肺
脉至，大而虚，如毛羽中人肤。其色赤白不泽，毛折乃死。其汤熨针石，别有正方，补养宣
导，今附于后。
《养生方》云∶多语则气争，肺胀口燥。
又云∶秋三月，此为容平。天气以急，地气以明。早卧早起，与鸡俱兴。使志安宁，以
缓秋形。收敛神气，使秋气平。无外其志，使肺气清。此秋气之应也，养收之道也。逆之则
伤肺，冬为飧泄。
《养生方·导引法》云∶肺脏病者，体胸背痛满，四肢烦闷，用嘘气出。
又云∶以两手据地覆之，口纳气，鼻出之，除胸中、肺中病也。
肺在五行中对应金，在秋季旺盛。其脉象像羽毛一样轻浮，其外在表现反映于鼻，其声音为哭，其气味为腥，其味道为辛，其体液为涕，其滋养皮肤和毫毛，其内藏魄，其面色为白；其经络属于手太阴经。肺与大肠相表里，大肠作为腑主表，肺作为脏主里。
如果肺气盛实，表现为气有余，就会发生喘息、咳嗽、气逆上冲，肩背疼痛，出汗，臀部、外阴、大腿、膝盖、腘窝、小腿、足部都疼痛，这是肺气实的证候，治疗应当采用泻法；如果肺气不足，就会气短、呼吸浅促无法接续，耳聋，咽喉干燥，这是肺气虚的证候，治疗应当采用补法。
关于四季的变化：肺病在冬季痊愈；如果冬季不愈，病情会在夏季加重；如果夏季不死，病情会在长夏（夏末秋初）维持稳定；到秋季则开始好转。关于天干日：在壬癸日（水日）痊愈；如果壬癸日不愈，病情会在丙丁日（火日）加重；如果丙丁日不死，病情会在戊己日（土日）维持稳定；到庚辛日（金日）则开始好转。关于时辰：傍晚时分感觉清爽舒适，半夜安静平和，中午时分病情加重。
肺的特性是宜收敛，应紧急食用酸味食物来收敛它，用酸味来补益肺，用辛味来泻肺。禁止食用寒凉饮食和穿着寒凉衣物。
肺部的脉诊部位，位于右手关前寸口处。正常的肺脉搏动，从容和缓，像落下的榆荚一样轻盈，称为肺平脉。秋季脉象以胃气为本底。秋季，肺金当令，其脉象浮、涩而短，这叫做平脉。如果反而得到浮大且洪大的脉象，这是心火乘袭肺金，火克金，属于大逆之证，十有八九死亡且不可治愈；如果反而得到沉濡且滑的脉象，这是肾水乘袭肺金，子扶母，即使有病也会自愈；如果反而得到缓和且长阿阿的脉象，这是脾土乘袭肺金，母归子，虽然生病也应当痊愈；如果反而得到弦而长的脉象，这是肝木乘袭肺金，木凌金，属于微邪，虽然生病也应当痊愈。
肺脉来时泛泛轻轻，像微风吹动鸟背上的羽毛。一息两至为正常，三至为离经（异常），四至为夺精（精气耗损），五至为死脉，六至为命尽。患肺病时，脉象上下往来像触摸鸡羽一样，称为肺病。肺病，其面色白，身体只觉寒冷而无发热，时常想要咳嗽，其脉象微迟，这是可以治疗的。死肺脉象，像物体漂浮水面，像风吹羽毛散乱，称为肺死脉。
秋季脉象中有轻微的毛象且兼有胃气为平脉，胃气少而毛象多为肺病，只有毛象而没有胃气则为死脉。毛象中带有弦象表示春季发病，弦象明显表示当前发病。真肺脉出现时，脉体大而虚，像羽毛中人肌肤的感觉。面色赤白无光泽，毛发枯折者将死亡。至于汤药、熨贴、针石等治疗方法，另有专门的方剂，补养宣导的方法，现在附在后面。
又说：秋季三个月，这叫作容平（万物成熟收敛）。天气急劲，地气清明。早睡早起，与鸡鸣同时起床。使情志安宁，以舒缓秋季肃杀之形。收敛神气，使秋气平和。不要使志向外驰，使肺气清肃。这是顺应秋气的做法，也是养收之道。违背它就会损伤肺，到了冬季会发生飧泄（完谷不化的腹泻）。
《养生方·导引法》说：肺脏有病的人，胸部背部疼痛胀满，四肢烦闷，可用“嘘”字诀呼气来调理。
又说：用双手支撑地面，身体倒伏，口吸气，鼻呼气，可以消除胸中和肺中的疾病。
The Lung corresponds to Metal in the Five Elements and is prosperous in Autumn. Its pulse is floating and light like feathers; its external manifestation reflects on the nose; its sound is weeping (crying); its odor is fishy; its taste is pungent; its fluid is nasal discharge; it nourishes the skin and body hair; it stores the Po (Corporeal Soul); its complexion is white; its meridian is the Hand-Taiyin (Lung Meridian). It is interior-exteriorly paired with the Large Intestine; as a Fu organ, the Large Intestine governs the exterior, while as a Zang organ, the Lung governs the interior.
If Lung Qi is excessive, manifesting as "Qi surplus," symptoms include panting, coughing, rebellious Qi ascending, pain in the shoulder and back, sweating, and pain throughout the buttocks, genitalia, thighs, knees, popliteal fossa, calves, and feet. This constitutes an Excess syndrome of Lung Qi, which should be treated with draining methods. If Lung Qi is deficient, symptoms include shortness of breath, inability to complete inhalation, deafness, and dry throat. This constitutes a Deficiency syndrome of Lung Qi, which should be treated with tonifying methods.
Regarding the Four Seasons: A Lung disease may heal in Winter; if not healed in Winter, it worsens in Summer; if death does not occur in Summer, it remains stable in Late Summer; and it begins to improve in Autumn. Regarding Heavenly Stems: Healing occurs on Ren-Gui days (Water days); if not healed, aggravation occurs on Bing-Ding days (Fire days); if death does not occur, stability is maintained on Wu-Ji days (Earth days); and improvement begins on Geng-Xin days (Metal days). Regarding Time of Day: The patient feels clearer in the late afternoon, quiet at midnight, and worse at noon.
The Lung desires contraction; therefore, sour flavors should be consumed urgently to contract it. Sour flavors are used to tonify the Lung, and pungent flavors are used to drain it. Cold food and cold clothing are prohibited.
The pulse location for the Lung is at the Cun-kou position anterior to the Guan position on the right wrist. A normal Lung pulse comes gently and rhythmically, like falling elm seeds, termed "Ping" (Normal) Lung Pulse. In Autumn, the Stomach Qi (digestive vitality) serves as the foundation. In Autumn, when Lung Metal is dominant, the pulse is floating, choppy, and short, which is called a Normal Pulse. If instead a floating, large, and surging pulse is obtained, this indicates Heart Fire encroaching upon Lung Metal (Fire overcoming Metal), representing a major reversal (Da Ni), which is fatal and incurable. If instead a deep, soft, and slippery pulse is obtained, this indicates Kidney Water encroaching upon Lung Metal (Child supporting Mother); even if diseased, it will heal spontaneously. If instead a relaxed, large, and long pulse is obtained, this indicates Spleen Earth encroaching upon Lung Metal (Mother returning to Child); although diseased, it will likely heal. If instead a wiry and long pulse is obtained, this indicates Liver Wood encroaching upon Lung Metal (Wood overwhelming Metal), representing a minor pathogen; although diseased, it will likely heal.
A Lung pulse that floats lightly, like a breeze blowing the feathers on a bird's back, with two beats per respiration is normal. Three beats indicate deviation from the classic pattern (Li Jing); four beats indicate depletion of essence (Duo Jing); five beats indicate death; six beats indicate the end of life. In Lung disease, the pulse moves up and down like feeling a chicken feather, termed Lung Disease. In Lung disease, the complexion is white, the body feels only cold without fever, there is frequent desire to cough, and the pulse is slightly slow; this is treatable. The dying Lung pulse floats like an object on water or like wind-blown feathers, termed Dying Lung Pulse.
In Autumn, a pulse with slight feathery quality and present Stomach Qi is normal; less Stomach Qi and more feathery quality indicates Lung disease; feathery quality without any Stomach Qi indicates death. Feathery quality with wiry quality indicates Spring illness; pronounced wiry quality indicates current illness. When the True Lung pulse appears, it is large and empty, like feathers touching human skin. If the complexion is red and white without luster and hair breaks, death ensues. Decoctions, moxibustion/warming therapies, needles, and stones have separate specific formulas; tonification, nourishment, and guidance exercises are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) states: Speaking too much causes Qi conflict, leading to Lung distension and dry mouth.
It also states: The three months of Autumn are called "Rong Ping" (Container and Level/Peaceful Convergence). The Heaven Qi becomes urgent/crisp, and the Earth Qi becomes clear. One should sleep early and rise early, waking with the rooster. One should keep the mind peaceful to缓 (slow/soothe) the autumn form. One should gather and store the Shen Qi (Spiritual Energy) to keep the Autumn Qi balanced. One should not let one's will wander outward, keeping the Lung Qi pure. This is responding to the Autumn Qi, the way of nourishing convergence. Violating this injures the Lung, leading to undigested diarrhea (Sun Xie) in Winter.
The *Yangsheng Fang · Daoyin Fa* (Guiding and Pulling Method) states: For those with Lung organ diseases, experiencing chest and back pain and fullness, and limb restlessness, one should exhale using the "Xu" (Hiss) sound technique.
It also states: Support oneself with both hands on the ground, invert the body, inhale through the mouth, and exhale through the nose; this eliminates diseases in the chest and lungs.
