右手指头肺相连。四十五动无忧虑。急极明知是中风。
言医人以食指探病患之右寸。乃肺脉也。亦须准前五九四十五动而
不歇。则无忧虑矣。若诊得其脉患极而弦。是为金衰不能制木。而风热
愈盛。知为中风之候矣。
按经云。右手寸口脉遍沉伏。乍小乍大。朝来浮大。暮来沉伏。浮大即太
过。上出鱼际。沉伏即下。不至关中。往来无常。时时复来者。榆叶枯落而
死。（叶一作荚）
更看二十余七度。忽然指下来往慢。肺冷莫言无大故。一朝肺绝脉沉沉。
染病卧床思此语。
诊得肺脉。于二十七动上。忽然来往慢慢而迟迟。则为寒。其肺冷可知
矣。然不得谓之无大故也。倘不以为意。于二十七动上一变慢而为沉。
则肺将绝矣。何也二十七动以四五除之。尚余其七。七为火之成数。以
五五除之。尚余其二。二为火之生数。合生成之数俱火。则肺金受伤。染
病卧床。悔将何及也。
十二动而又不来。咳嗽吐脓兼难补。发直如麻只片时。扁鹊也。应难救获。
倘诊肺脉。于十二动上而又不见其来。夫肺金也。十二动以二五除之。
尚余其二。二为火之生数。以一五除之。尚余其七。七为火之成数。合生
成之数俱火。洁古曰。金得火而缺也。金被火伤。则咳嗽吐脓。欲泻其肺。
则肺已受伤。欲补则反助贼邪。及其终也。则发直如麻。纵有卢扁。有何益焉。
The Cun Kou pulse at the tip of the right hand is connected to the Lung. If the pulse beats forty-five times without pause, there is no cause for worry. If the pulse is extremely rapid and clearly wiry (Xian Mai), it is known to be Wind-Stroke (Zhong Feng).
The physician uses the index finger to palpate the patient's right Cun Kou pulse, which is the Lung pulse. It must also conform to the previous rule of ninety-four-forty-five beats without cessation; thus, there is no worry. If the pulse is found to be severely afflicted and wiry, this indicates that Metal (Lung) is deficient and cannot control Wood (Liver), causing Wind-Heat to become even more vigorous. It can be known as a sign of Wind-Stroke.
According to the classics: The right hand Cun Kou pulse is generally deep and hidden (Chen Fu), sometimes small and sometimes large. In the morning, it is floating and large (Fu Da); in the evening, it is deep and hidden. Floating and large indicates excess (Tai Guo), with the pulse qi emerging above the Yu Ji area. Deep and hidden indicates deficiency, failing to reach the Guan Zhong area. The pulse comes and goes irregularly, appearing from time to time; this is like the falling of elm leaves, indicating death. ("Leaf" is written as "pod" in some versions).
Furthermore, observe if after twenty or seven beats, the pulse suddenly feels slow in its coming and going under the fingers. Lung Cold should not be dismissed as having no major consequence. Once the Lung Qi perishes, the pulse becomes deep. Reflect on these words when bedridden by illness.
When diagnosing the Lung pulse, if at twenty-seven beats the pulse suddenly comes slowly and迟 (chi/slow), it belongs to Cold. The coldness of the Lung is evident. However, it cannot be said that there is no major issue. If neglected, and at twenty-seven beats the pulse changes from slow to deep, then the Lung Qi is about to perish. Why? Twenty-seven beats divided by four and five leaves a remainder of seven. Seven is the completed number of Fire. Divided by five and five, it leaves a remainder of two. Two is the generated number of Fire. Combining the generated and completed numbers, all belong to Fire. Thus, Lung Metal is injured, leading to being bedridden by illness, and regret will be of no avail.
If twelve beats occur and the pulse does not come again, accompanied by coughing, expectoration of pus, and difficulty in tonification. Hair stands straight like hemp for only a moment. Even if Bian Que were alive, he would hardly be able to save the patient.
If, upon diagnosing the Lung pulse, at twelve beats the pulse fails to appear again. The Lung belongs to Metal. Twelve beats divided by two and five leaves a remainder of two. Two is the generated number of Fire. Divided by one and five, it leaves a remainder of seven. Seven is the completed number of Fire. Jiegu said: Metal meets Fire and becomes deficient. When Metal is injured by Fire, symptoms such as coughing and expectorating pus occur. To purge the Lung, the Lung is already injured; to tonify the Lung, one instead assists the thief pathogen. At the end stage, the hair stands straight like hemp. Even if Lu Yi (Lu Xun, referring to famous physicians) and Bian Que were present, what good would they do?
