钱氏曰∶肝脏病见秋，木旺，肝强胜肺也，宜补肺泻肝，轻则肝病退，重者唇白而死。
肺病见春，金旺，肺强胜肝，当泻肺，轻者肺病退，重者目淡青，必发惊，更有赤者，发搐为肝怯，当目淡青也。
心病见冬，火旺，心强胜肾，当补肾泻心，轻者心病退，重者下窜不语，肾气怯也。
肾病见夏，水胜火，肾胜心也，宜泻肾，轻者肾病退，重者悸动当搐也。
脾病见四时，皆仿此治之。顺者易治，逆者难治。脾怯面目赤黄，五脏相反，当随症治之。
一肺病又见肝症，切牙多呵欠者，易治。肝虚不胜肺故也。若目直大叫哭，项急烦闷者，难治。盖肺病久则虚冷，
肝强实而反胜肺，视病之邪久虚实，虚则补母，实则泻子，斯得之矣。
洁古云∶肝胜肺则肝病，身热发搐，又见肺虚喘而气短，病见于申酉戌时，是肝真强也。
《内经》曰∶受所制而不能制，谓之真强，法当补脾肺而泻肝，导赤散、泻黄散主之。
按刘宗浓云∶此皆五脏相胜，病机不离五行生克制化之理。盖小儿初生襁褓，未有七情六欲，只是形体脆弱，血气
未定，脏腑精神未完，所以有脏气虚实胜乘之病，但世俗不审此理，往往遇是即指为外感内伤而用药，致枉死者多矣，
悲夫！然钱氏论之太略，洁古补之，今特参附，以惠无穷云。

导赤散 见惊风症内，一见五淋症内。
泻黄散 见热症内。
Qian Yi stated: When liver disease manifests in autumn, the Wood qi is prosperous. The liver is strong and overacts on the Lung Metal. Treatment should involve tonifying the Lung and draining the Liver. In mild cases, the liver disease will recede; in severe cases, the lips will turn white, leading to death.
When lung disease manifests in spring, the Metal qi is prosperous. The lung is strong and overacts on the Liver Wood. Treatment should involve draining the Lung. In mild cases, the lung disease will recede; in severe cases, the eyes will appear pale cyan, inevitably leading to *Jing Feng* (Wind Stirring / Convulsive Disorder). If the eyes are red, convulsions (*Chou*) will occur due to liver deficiency; this condition should present with pale cyan eyes.
When heart disease manifests in winter, the Fire qi is prosperous. The heart is strong and overacts on the Kidney Water. Treatment should involve tonifying the Kidney and draining the Heart. In mild cases, the heart disease will recede; in severe cases, the patient will exhibit retraction of the genitals and inability to speak, indicating weakness of Kidney Qi.
When kidney disease manifests in summer, Water overcomes Fire. The kidney overacts on the Heart. Treatment should involve draining the Kidney. In mild cases, the kidney disease will recede; in severe cases, palpitations and tremors accompanied by convulsions will occur.
Spleen disease occurring in any of the four seasons should be treated following these principles. Cases following the generative cycle are easy to treat; those violating it are difficult. Spleen deficiency presents with red and yellow complexion. When the five Zang organs act against each other abnormally, treatment must be tailored to the specific symptoms.
If lung disease presents with liver symptoms, such as teeth grinding and frequent yawning, it is easy to treat. This is because the Liver is deficient and cannot control the Lung. However, if the eyes are fixed, there is loud crying, neck stiffness, and irritability, it is difficult to treat. This is because prolonged lung disease leads to deficiency-cold, while the Liver becomes strong and excess, thereby counter-acting the Lung. By observing the duration of the pathogen and the deficiency or excess nature, one should tonify the Mother organ in deficiency cases and drain the Child organ in excess cases; thus, the correct approach is achieved.
Zhang Yuansu (Jiegu) stated: When Liver overacts on Lung, liver disease occurs, characterized by body heat and convulsions, along with lung deficiency manifesting as wheezing and shortness of breath. The pathology appears during the Shen, You, and Xu hours, indicating true strength of the Liver.
The *Huangdi Neijing* states: "Being controlled but unable to control others is called 'True Strength'." The method should be to tonify the Spleen and Lung and drain the Liver, primarily using *Daochi San* (Guiding Out Red Powder) and *Xiehuang San* (Draining Yellow Powder).
Commentary: Liu Zongnong stated: These are all diseases of the five Zang organs overcoming each other; the pathogenesis does not depart from the principles of the mutual generation and restriction of the Five Elements. Since infants are still in swaddling clothes, devoid of the seven emotions and six desires, their physical form is fragile, blood and qi are undetermined, and the zang-fu spirit and essence are incomplete. Therefore, diseases arise from the deficiency and excess of zang qi leading to overcoming and multiplying. However, laypeople do not understand this principle and often misidentify these conditions as external contraction or internal injury, administering medication accordingly, resulting in many wrongful deaths. How tragic! Qian Yi's discussion was too brief, and Zhang Yuansu supplemented it. I now specially reference and add annotations to benefit future generations.
