咳血，皮毛焦悴。（虚火燥肺。）但虚宜补，人参、黄 、（大补肺气。）蛤蚧、（补肺定喘。）

）桂枝、（温经通营卫。）苏叶、（散寒。）荆芥、白芷、羌活，（温散。）辛凉如薄荷、（辛凉。
如果病人不能耐受风寒，（肺主皮毛。）出现气喘急促、说话断断续续，（这是肺气亏损的表现。）频繁咳嗽吐痰，（这是因为水液津液不能正常布散全身。）身体虚弱且伴有热象，就会引发肺痿病，（这是由于肺中津液枯涸所致。）百合病，（由手太阴肺经虚热引起。）失音，（肺金受损。）干咳，咳血，皮肤毛发干枯憔悴。（这是虚火燥灼肺部所致。）对于单纯的虚证应当采用补法，可选用人参、黄芪、（大补肺气。）蛤蚧、（补肺定喘。）白肺头、（以脏补脏，即补肺。）五味子（能收敛耗散的肺气。）等药物。如果是虚证兼有热象，适宜使用滋养清润肺金的药物，如北沙参、（清润肺金。）麦冬、燕窝、（大补肺阴。）百合、（象形益肺。）秫米、（平和补益肺金。）川贝母、（清肺化痰。）款冬花、（润肺化痰。）桑白皮、（泻肺化痰。）地骨皮、（治疗肺热出汗。）马兜铃、（清肺止咳。）天花粉、桑叶（润燥清肺。）像清燥救肺汤、四阴煎、人参固本丸、补肺阿胶散、泻白散等方剂，都可以酌情选用。如果受到外邪侵袭则会导致哮喘，（风寒之邪闭塞肺气。）怕风、身体发热、流清鼻涕，（这都是因为受邪后肺气不能宣发所致。）或者出现咳嗽，表现为痧症、疹病、温热病、肺痈，病情严重时会出现瘙痒、瘰疬、疥疮等皮肤病，（都是因为寒邪郁闭皮毛，导致肺气不宣而形成的各种病症。）有的适宜用温散法，有的适宜用辛凉法，需根据症状来选用。温散法如麻黄、（肺有实邪最重者可用。）桂枝、（温通经络调和营卫。）紫苏叶、（散寒。）荆芥、白芷、羌活，（温散解表。）辛凉法如薄荷、（辛凉解表。）
If the patient cannot tolerate wind and cold, (The Lung governs the skin and hair.) presenting with panting and rapid breathing, and interrupted speech, (this indicates deficiency of Lung Qi.) frequent coughing and expectoration, (due to the failure of body fluids to distribute throughout the body.) If there is deficiency accompanied by heat, it leads to Fei Wei (Lung Withering), (caused by the depletion of Lung fluids.) Baihe Bing (Lily Disease), (resulting from deficient-heat in the Hand-Taiyin Lung meridian.) aphonia, (damage to Metal of the Lung.) dry cough, hemoptysis, and withered, dry skin and hair. (This is due to deficient-fire drying out the Lungs.) For pure deficiency, tonification is appropriate; herbs such as Renshen (Ginseng Radix et Rhizoma), Huangqi (Astragali Radix), (greatly tonifies Lung Qi.) Gejie (Gecko), (tonifies the Lung and calms asthma.) Baifeitou (White Lung Head), (using organ to tonify the organ, i.e., tonifying the Lung.) Wuweizi (Schisandrae Fructus) (can astringe scattered Lung Qi.) etc. are selected. For deficiency complicated by heat, nourishing and clearing the Lung metal is suitable; herbs such as Beishashen (Glehniae Radix), Maidong (Ophiopogonis Tuber), Yanwo (Swallow's Nest), (greatly tonifies Lung Yin.) Baihe (Lilii Bulbus), (symbolically benefits the Lung.), Shumi (Sorghum Vulgare), (mildly tonifies Lung Metal.), Chuanbei (Fritillariae Cirrhosae Bulbus), (clears the Lung and resolves phlegm.) Kuandonghua (Farfarae Flos), (moistens the Lung and resolves phlegm.) Sangbaipi (Mori Cortex), (drains the Lung and resolves phlegm.) Digupi (Lycii Cortex), (treats lung-heat sweating.) Madouling (Aristolochiae Yentoushanensis Caulis), (clears the Lung and stops cough.) Huafen (Trichosanthis Radix), Sangye (Mori Folium) (moistens dryness and clears the Lung.) Formulas such as Qingzao Jiufei Tang (Clear Dryness and Rescue the Lung Decoction), Siyin Jian (Four Yin Decoction), Renshen Guben Wan (Ginseng Root-Strengthening Pill), Bufeijiao'ou San (Tonify Lung and Donkey-Hide Gelatin Powder), Xiebai San (Drain White Powder) can all be considered. If affected by pathogenic factors, asthma may occur, (wind-cold pathogens obstruct Lung Qi.) aversion to wind, fever, and runny clear nasal discharge, (all due to the failure of Lung Qi to diffuse after pathogen invasion.) or cough, manifesting as Sha (sand-like eruptions), Zhen (rashes), Wenre (warm-heat diseases), Fei Yong (Lung Abscess); at its extreme, it may result in itching, Luoli (scrofula), Jiechuang (scabies and sores). (All these conditions arise from cold stagnation in the skin and hair, leading to impaired diffusion of Lung Qi.) Some cases require warm dispersal, others require acrid-cool dispersal, chosen according to the symptoms. Warm dispersal includes Mahuang (Ephedrae Herba), (for severe excess pathogens in the Lung.) Guizhi (Cinnamomi Ramulus), (warms meridians and harmonizes Ying and Wei.) Ziye (Perillae Folium), (dispels cold.) Jingjie (Schizonepetae Spica), Baizhi (Angelicae Dahuricae Radix), Qianghuo (Notopterygii Rhizoma et Radix), (warm dispersal.) Acrid-cool methods include Bohe (Menthae Haplocalycis Herba), (acrid-cool dispersal.)
