叙曰：各种疾病都足以导致虚损劳瘵，治疗这类疾病必须探究其病因。这种病，自古以来高明的医生往往难以着手治疗，正如病情已经形成后才用药治疗，好比口渴了才去挖井，打仗了才去铸造兵器，不也太晚了吗？因此历代精通医术的哲人，撰写论述劳瘵的方论，只是简要地陈述这些证候罢了，如果加以扩充发挥，那么变化就会层出不穷，全在于人的用心思考而已。
黄耆（四两） 人参 白术 桂心（各二两） 附子（二十铢） 生姜（八两） 大枣（十枚）
五脏都有劳损，劳损在肺脏的，表现为短气、虚寒、皮毛枯涩、津液不通、气力亏损匮乏、脉象迟缓者，此方主治。
肺主气，长期悲哀喘咳，就会形成肺劳。肺劳导致气短且声音微弱。气属于阳，阳气虚则生寒，所以出现虚寒症状。肺主管皮毛，肺劳则没有津液来滋润皮肤和毛发，所以出现枯涩。气有余则物体润泽，津气和津液不足，就无法化生津液，所以出现口干而津液不通；气壮盛则身体强健，气衰馁则身体虚弱，如今肺被劳伤，所以气力亏损匮乏。脉象迟缓表示有寒，脉象缓弱表示有虚。黄耆、人参，是甘温性质的药物，所以能补气。医经说：“损伤肺脏的要补益其气”，因此使用这两味药。桂心、附子，是辛热性质的药物，气虚则阴邪聚集而产生寒，热能壮大气，因此使用这两味药。白术、生姜、大枣，是调理脾胃的药物。医经说：“虚证要调治其母脏”，脾是肺的母脏，因此使用这三味药。这个方剂，以上所述都是虚寒的证候，所以配合使用是适宜的。如果是肺热且脉数者，就不适宜用此方，应当主治二母散。
共研为细末。
治疗肺脏有两种方法：气虚而阴邪聚集，就像前方所说的温补法。肺金衰弱而火邪乘袭，就像此方所说的滋阴法。适宜温补的容易治愈，适宜滋阴的难以治疗。因为火来乘袭肺金，称为贼邪，将要发展为肺痿，非常难治。这个方剂中，知母和贝母都是苦寒性质的药材，苦味能坚固肺金，寒性能胜除热邪，所以古人用它来主治。
Preface: Various diseases can lead to deficiency and consumptive disease (Xu Sun Lao Zhai). Those who treat it must investigate the cause. This illness, since ancient times, has been difficult for even the most skilled physicians to manage. It is akin to digging a well only when thirsty or forging weapons only when battle begins; is this not too late? Therefore, medical sages of past dynasties have written treatises on formulas for consumptive disease, briefly stating these syndromes. If expanded upon, changes become myriad, depending entirely on the practitioner's insight.
Huangqi (Radix Astragali) (4 liang), Renshen (Radix Ginseng), Baizhu (Rhizoma Atractylodis Macrocephalae), Guixin (Cortex Cinnamomi), each 2 liang; Fuzi (Radix Aconiti Lateralis Preparata) (20 zhu); Shengjiang (Rhizoma Zingiberis Recens) (8 liang); Dazao (Fructus Jujubae) (10 pieces).
Each of the five zang organs can suffer from labor/damage. When the lung is damaged by labor, symptoms include shortness of breath, deficiency-cold, withered and dry skin and hair, obstruction of body fluids, depletion of qi strength, and a slow and moderate pulse. This formula is indicated for such cases.
The Lung governs Qi. Prolonged sorrow, wheezing, and coughing can lead to Lung Labor (Fei Lao). Lung Labor causes shortness of breath and a weak voice. Qi belongs to Yang; Yang deficiency leads to cold, hence the manifestation of deficiency-cold. The Lung governs the skin and hair. In Lung Labor, there is insufficient fluid to nourish the skin and hair, resulting in withered and dry textures. Abundant Qi moistens objects; insufficient Qi and fluids fail to transform into fluids, leading to dry mouth and obstructed fluids. Strong Qi makes one robust; depleted Qi makes one weak. Since the Lung is injured by labor, Qi strength is depleted. A slow pulse indicates Cold; a moderate pulse indicates Deficiency. Huangqi and Renshen are sweet and warm, thus they can tonify Qi. The Classic states: "For damage to the Lung, benefit its Qi." Hence, they are used. Guixin and Fuzi are acrid and hot. Qi deficiency allows Yin pathogens to gather, causing Cold; Heat can strengthen Qi, hence they are used. Baizhu, Shengjiang, and Dazao are herbs for regulating the Spleen and Stomach. The Classic states: "For deficiency, regulate the mother organ." The Spleen is the mother of the Lung; hence, they are used. This formula is suitable because all the aforementioned conditions are deficiency-cold syndromes. However, if there is Lung Heat with a rapid pulse, this formula is inappropriate; instead, Er Mu San should be used.
Zhimu (Radix Anemarrhenae, de-haired, stir-fried), Beimu (Bulbus Fritillariae Cirrhosae, core removed, lightly stir-fried), each 5 qian.
Grind together into fine powder.
This formula is indicated for Lung Labor accompanied by Heat, where patients cannot tolerate Qi-tonifying preparations.
There are two methods for treating the Lung: For Qi deficiency with Yin accumulation, use warming and tonification as in the previous formula. For Lung Metal deficiency with Fire encroachment, use yin-nourishment as in this formula. Cases suitable for warming and tonification are easier to cure; those suitable for yin-nourishment are harder to treat. Because Fire encroaching on Metal is called "Thief Evil," and may develop into Lung萎 (Fei Wei/Lung Atrophy), it is very difficult to treat. In this formula, both Zhimu and Beimu are bitter and cold. Bitterness can firm the Metal (Lung), and Coldness can overcome Heat; thus, ancients used it for this purpose.
