动者，动穴也。以各经之穴动，则知其病也。所生病，本经自病也。诸病，他经合病也，或由本经而累及
他经，或由他经而干犯本经，皆是也。气盛，邪气之盛也。气虚，正气之虚也。统自病、合病、气盛、气虚四
项，而病情约略殆尽，其间每项各举数证以见意。他经亦有止言自病、合病二项，不复详言盛虚诸病者，盖即
此可以类推也。如肺胀满致膨膨而喘急咳嗽，此脏病也。缺盆中痛，甚则交两手而瞀，此经络病也。缺盆虽
大肠所经之地，而络脉交于大肠，仍肺之经络也，故皆为肺生之病。以下为咳为喘，病与上同，而与上气、渴、
烦心等病并举，则他经所累也。胸满亦与胀满相同，胀满专以肺言，此则兼诸气之 郁也。 臂内痛，亦本经
之病，与上两手掣痛无异，而与厥、掌中热并言，则心与心主之所累及也。肩背疼痛，气盛气虚皆同，而所因
异也。汗出中风，肺主皮毛故也。小便数而欠与溺色变，皆肾与膀胱之病，母病累及子也。少气不足以息，本
脏病也。以上所叙诸证甚详，其有未备者，更以本草标本诸病参看。
肺藏魄，属金，总摄一身元气，主闻，主哭，主皮毛。
本病（脏腑之病）
诸气 郁，（肺主气。）诸痿，（肺为五脏华盖，故五脏之痿皆属于肺。）气短，咳嗽，上逆，（同经。）
咳唾脓血，（肺痈也。）不得卧，（肺藏魄也。）小便数而
欠，遗失不禁。（同经。）
标病（经络之病）
洒淅寒热，（肺主皮毛。）伤风自汗，肩背痛冷， 臂前廉痛。（同经。）
所谓“动”，是指触动穴位。通过触动各经络的穴位，就能知晓病情。“所生病”，是指本经自身发生的病变。“诸病”，是指其他经络合并发生的病变，这包括由本经牵连波及他经，或由他经侵犯影响本经的情况，都属于此类。“气盛”，是指邪气亢盛。“气虚”，是指正气虚弱。综合自病、合病、气盛、气虚这四项内容，病情的大致情况就概括无遗了，其中每一项都列举了几个证候来阐明其意。其他经络也有只提及自病、合病两项，不再详细论述气盛气虚等病症的，大概可以通过这些情况类推。例如肺脏胀满导致胸部膨隆、气喘急促、咳嗽，这是脏腑本身的病变。缺盆（锁骨上窝）部位疼痛，严重时甚至双手交叉按压胸口而昏闷，这是经络的病变。缺盆虽然是大肠经循行的部位，但络脉与大肠相交，仍属于肺的经络系统，所以这些都是肺经产生的疾病。以下出现的咳嗽、气喘，病症与上面相同，但如果同时伴有上气、口渴、心烦等症状，则是其他经络受累所致。胸满也与胀满相似，但胀满是专门针对肺而言的，这里的胸满则兼有各种气机郁滞的情况。手臂内侧疼痛，也是本经的病变，与前面提到的两手牵引性疼痛没有区别，但如果同时伴有四肢厥冷、掌心发热，则是心包经受累所致。肩背部疼痛，无论是气盛还是气虚表现相同，但致病原因不同。出汗后感受风邪，是因为肺主司皮毛。小便频数且排尿不畅，以及尿液颜色改变，都是肾和膀胱的病变，这是母脏病变累及子脏的表现。少气不足以呼吸，是本脏自身的病变。以上叙述的各种证候非常详尽，如果有未涵盖的，可以进一步参考本草书中关于标本诸病的记载。
肺藏魄，五行属金，总摄全身元气，主管嗅觉，主管哭泣，主管皮毛。
本病（脏腑之病）
各种气机郁滞，（因为肺主气。）各种痿证，（肺为五脏的华盖，所以五脏的痿证都归属于肺。）气短，咳嗽，气逆，（同属一经。）咳吐脓血，（即肺痈。）不能平卧，（因为肺藏魄。）小便频数且排尿不尽，大小便失禁。（同属一经。）
标病（经络之病）
恶寒发热，（肺主皮毛。）伤风自汗，肩背疼痛发冷，手臂前缘疼痛。（同属一经。）
"Movement" refers to the stimulation of acupoints. By stimulating the acupoints of each meridian, one can ascertain the pathology. "Diseases generated by the meridian" refer to pathologies originating within the same meridian itself. "Various diseases" refer to combined pathologies involving other meridians; this includes conditions where the primary meridian affects others, or where other meridians invade the primary meridian. "Excess of Qi" refers to the excess of pathogenic factors. "Deficiency of Qi" refers to the deficiency of healthy Qi. Synthesizing these four categories—self-originated disease, combined disease, Qi excess, and Qi deficiency—the general scope of pathological conditions is comprehensively covered. Each category presents several specific manifestations to illustrate its meaning. For other meridians, only self-originated and combined diseases are mentioned, without detailed discussion on excess or deficiency patterns; this implies that such patterns can be inferred by analogy. For instance, lung distension causing chest fullness, palpitation, rapid breathing, and coughing constitutes a Zang-organ pathology. Pain in the supraclavicular fossa (Quepen), severe cases of which involve crossing both hands over the chest leading to dizziness or confusion, constitutes a meridian pathology. Although the supraclavicular fossa is traversed by the Large Intestine meridian, its collaterals connect with the Large Intestine yet remain part of the Lung's meridian system; thus, these are all diseases generated by the Lung. Cough and wheezing appearing below share similarities with the above, but when presented alongside symptoms like rebellious Qi, thirst, and vexation, they indicate involvement from other meridians. Chest fullness is similar to distension; while distension specifically pertains to the Lung, chest fullness here involves the stagnation of various types of Qi. Pain in the medial aspect of the arm is also a pathology of the primary meridian,无异 to the pulling pain in both hands mentioned earlier; however, when accompanied by cold limbs and heat in the palms, it indicates involvement from the Heart and Pericardium. Shoulder and back pain present similarly regardless of whether due to Qi excess or deficiency, though the etiology differs. Sweating followed by wind-strike occurs because the Lung governs the skin and hair. Frequent urination with incomplete emptying and changes in urine color are pathologies of the Kidney and Bladder, representing a mother-organ pathology affecting the child organ. Shortness of breath and inability to take deep breaths constitute a pathology of the primary Zang organ. The aforementioned descriptions of various syndromes are quite detailed; for any omissions, one should consult the materia medica regarding the root and branch diseases.
The Lung stores the Po (Corporeal Soul), belongs to Metal, governs the Yuan Qi (Original Qi) of the entire body, controls the sense of smell, governs crying, and governs the skin and hair.
Root Diseases (Zang-Organ Pathologies)
Various Qi stagnations, (as the Lung governs Qi.) Various Wei syndromes (Flaccidity syndromes), (as the Lung is the canopy of the five Zang organs, all Wei syndromes of the five Zang organs belong to the Lung.) Shortness of breath, cough, rebellious Qi, (belonging to the same meridian.) Coughing up pus and blood, (i.e., Lung Abscess.) Inability to lie flat, (as the Lung stores the Po.) Frequent urination with incomplete emptying, incontinence of urine and feces. (Belonging to the same meridian.)
Branch Diseases (Meridian Pathologies)
Chills and fever alternating, (as the Lung governs the skin and hair.) Wind-strike with spontaneous sweating, shoulder and back pain with cold sensation, pain along the anterior margin of the arm. (Belonging to the same meridian.)
