鸡胸龟背，古方书列于一门，未能条分缕晰，治法甚略。予按∶鸡胸发于肺，龟背则肝脾肾肺皆有之。肺位最高，
处于胸中，积而生热，肺气上浮，胸骨高起，是为鸡胸。咳嗽或无，气粗必见，日久羸瘦，发热毛焦，唇红面赤，即成
气疳之候。气疳者，即肺疳也，宜清降肺气，气降痰消，胸骨自平。又有鸡胸龟背并发者，肺有痰热，客风从风门而入
于肺，其背庀于脊之第三椎，乃肺气壅遏，胸背之骨撑凸而起。有单脊凸而胸不高者，其候短气头低，兼咳嗽，腰背板
强，久则两足软弱，甚至不能站立。肺为肾母，肾为肺子，清肃不降，肾水不生，肺虚不能荣运，脏腑灌溉经络，上元
竭而下源惫。经云∶所谓肺热叶焦，为痿 是也。虽然下枯，还当治肺，肺气清肃，金来生水，子受其荫矣。古方之龟
胸丸用硝黄，未免伤其正气。龟背，之用六味鹿茸，奈地萸之滞腻，鹿茸之助阳，非不中病，必致增剧。且肺为清虚之
脏，病在上者只可轻清。余经验数方录后，以为后学人参考，非可云法，聊补前人之未备耳。

Chicken breast (pectus carinatum) and turtle back (kyphosis) were grouped into one category in ancient medical texts, but the analysis was not detailed and clear, and the treatment methods were very brief. I have examined this: Chicken breast originates from the Lung, whereas turtle back involves the Liver, Spleen, Kidney, and Lung. The Lung is located at the highest position, within the chest. If heat accumulates and generates internally, Lung Qi floats upward, causing the sternum to protrude; this is called chicken breast. Cough may or may not be present, but coarse breathing will definitely be seen. After a long time, the body becomes emaciated, fever occurs, hair becomes dry and brittle, lips are red, and the face is flushed; this constitutes the syndrome of Qi Gan (Lung Wasting-Thirst). Qi Gan refers to Lung Gan, and the appropriate treatment is to clear and descend Lung Qi. When Qi descends, phlegm dissipates, and the sternum naturally flattens. There are also cases where chicken breast and turtle back occur simultaneously. This is due to phlegm-heat in the Lung, with exogenous wind entering the Lung via the Fengmen (BL12) acupoint. The third thoracic vertebra on the back becomes concave (Pi), caused by the obstruction and stagnation of Lung Qi, leading to the protrusion of the chest and back bones. In cases where only the spine protrudes without chest elevation, the symptoms include shortness of breath, drooping head, accompanied by cough, stiffness and rigidity of the waist and back. Over time, both legs become weak, and even standing becomes impossible. The Lung is the mother of the Kidney, and the Kidney is the child of the Lung. If the Lung's clearing and descending function fails, Kidney Water cannot be generated. Lung deficiency fails to nourish and circulate, and the Zang-Fu organs fail to irrigate the meridians, resulting in the exhaustion of the upper source and the fatigue of the lower source. The Classics state: "What is meant by lung heat scorching the leaves, leading to Wei syndrome (flaccidity syndrome)," is precisely this. Although the lower part is withered, treatment should still focus on the Lung. If Lung Qi is clear and descending, Metal generates Water, and the child organ (Kidney) receives its benefit. Ancient formulas like Guixiong Wan use Nuxiao (Mirabilite) and Huanglian (Rhubarb), which inevitably damage healthy Qi. For turtle back, Liuwei Dihuang Wan plus Lurong (Deer Antler) is used; however, Shanzhuyu (Cornus officinalis) is cloying and stagnant, and Lurong aids Yang. Although not entirely inappropriate for the disease, it must inevitably exacerbate the condition. Moreover, the Lung is a pure and empty organ; diseases in the upper jiao can only be treated with light and clear agents. I record several empirically effective formulas below for reference by future students. These are not definitive methods, but merely an attempt to supplement the deficiencies of predecessors.
