肺痿吐涎沫而不咳者，其人不渴，必遗尿，小便数。所以然者，以上虚不能制下故也
。此为肺中冷，必眩多涎唾，甘草干姜汤以温之；若服汤已渴者，属消渴。
【注】
咳而不吐涎沫者，肺燥咳也；咳而吐涎沫者，肺热痿也。若似肺痿之吐涎沫而不咳者

多涎唾。所以然者，以上焦阳虚，不能约制下焦阴水，下焦之水泛上而唾涎沫，用甘
草干姜汤以温散肺之寒饮也。如服汤已渴者，属消渴，谓始先不渴，服温药即转渴者
，不但非肺中热，亦非肺中冷，乃胃中热也，则不当以属肺中冷寒饮治之，当以属胃
中热消渴治之也。

咳而上气，喉中水鸡声，射干麻黄汤主之。

咳逆上气，谓咳则气上冲逆也。上条发明不咳而吐涎沫者，非为肺痿，是为肺冷也。
此条发明咳而不吐涎沫者，亦非肺痿，亦为肺冷也。上条以不渴，小便数，多唾涎沫

肺痿病表现为吐涎沫但不咳嗽的患者，口中不渴，必然出现遗尿、小便频数。之所以如此，是因为上焦虚寒不能制约下焦的缘故。
这属于肺中寒冷，必然伴有头晕、多涎唾的症状，应用甘草干姜汤来温补；如果服用汤药后出现口渴的，则属于消渴病。
【注】
咳嗽但不吐涎沫的，是肺燥引起的咳嗽；咳嗽且吐涎沫的，是肺热导致的肺痿。如果症状类似肺痿，表现为吐涎沫却不咳嗽的，这是肺中有冷饮，并非肺中形成热性肺痿。
肺中寒冷，那么患者必然不口渴，出现遗尿和小便频数，头晕且多涎唾。之所以如此，是因为上焦阳气虚弱，不能约束控制下焦的阴水，导致下焦之水泛溢上行而吐出涎沫，应用甘草干姜汤来温散肺中的寒饮。
如果服用汤药后出现口渴的，属于消渴病，意思是起初不渴，服用温热药物后转为口渴的，这不仅是非肺中热证，也非肺中冷证，而是胃中有热，就不应当按肺中冷寒饮来治疗，而应当按胃中热导致的消渴来治疗。

咳嗽且气逆上冲，喉中有像青蛙叫一样的声音，用射干麻黄汤主治。
【注】
咳逆上气，是指咳嗽时气机上冲逆乱。上一条论述了不咳嗽而吐涎沫的情况，这不是肺痿，而是肺冷。
这一条论述了咳嗽但不吐涎沫的情况，也不是肺痿，同样是肺冷。上一条以不渴、小便频数、多唾涎沫为肺中冷的特征，所以用干姜辅助甘草，是以温中为主。
这一条以气上逆、喉中有水鸡声为肺经寒的特征，所以用生姜辅助麻黄，是以发散表邪为主。病机同为冷饮致病，但有在表在里的区别；方剂同属辛温性质，但有主温主散的差异。
所谓“水鸡声”，是指水与气相互冲击发出的声音，在喉中连续不断。

In pulmonary consumptive disease (Fei Wei) characterized by expectoration of saliva and froth without coughing, the patient has no thirst and inevitably experiences enuresis and frequent urination. This occurs because deficiency-cold in the upper jiao fails to control the lower jiao.
This indicates cold in the lungs, accompanied by dizziness and abundant saliva/froth; Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction) should be used to warm the lungs. If thirst develops after taking the decoction, it belongs to xiaoke (wasting-thirst syndrome).
[Annotation]
Coughing without expectorating saliva/froth indicates dryness-cough of the lungs; coughing with expectorating saliva/froth indicates pulmonary consumptive disease caused by lung-heat. If the symptoms resemble pulmonary consumptive disease, specifically expectorating saliva/froth without coughing, this indicates cold-fluid retention in the lungs, not pulmonary consumptive disease formed by heat.
When there is cold in the lungs, the patient will certainly have no thirst, experience enuresis and frequent urination, dizziness, and abundant saliva/froth. The reason for this is that yang-deficiency in the upper jiao cannot constrain the yin-water of the lower jiao, causing water from the lower jiao to overflow upward, resulting in the expectoration of saliva/froth. Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction) should be used to warm and disperse the cold-fluid in the lungs.
If thirst occurs after taking the decoction, it belongs to xiaoke (wasting-thirst syndrome). This means that initially there was no thirst, but it turned into thirst after taking warming herbs. This indicates neither lung-heat nor lung-cold, but rather heat in the stomach. Therefore, it should not be treated as cold-fluid in the lungs, but rather as wasting-thirst caused by stomach-heat.

For coughing with rebellious qi ascending and a sound in the throat resembling that of a water-frog, Shexgan Mahuang Tang (Throatwort and Ephedra Decoction) is the primary formula.
[Annotation]
"Ke ni shang qi" refers to coughing accompanied by rebellious upward rushing of qi. The previous clause explained that expectorating saliva/froth without coughing is not pulmonary consumptive disease, but cold-lungs.
This clause explains that coughing without expectorating saliva/froth is also not pulmonary consumptive disease, but cold-lungs. In the previous clause, the absence of thirst, frequent urination, and abundant saliva/froth indicated cold in the lungs; thus, Ganjiang (Dried Ginger) assisted Gancao (Licorice) to primarily warm the middle jiao.
In this clause, rebellious qi and the "water-frog sound" in the throat indicate cold in the lung meridian; thus, Shengjiang (Fresh Ginger) assisted Mahuang (Ephedra) to primarily disperse exterior pathogens. Although the pathogenic factor is cold-fluid in both cases, there is a distinction between interior and exterior locations. Although the formulas share acrid-warm properties, there is a difference between primarily warming and primarily dispersing.
The term "water-frog sound" refers to the sound produced by the collision of fluid and qi, continuous in the throat.
