【歌】表虚血弱汗成流，湿证淋漓不肯休。痰证津津常浃背，亡阳气脱汗如油。阴虚盗汗兼无血，熟睡沾
衾觉即收。心汗盖缘思虑得，圆圆一片在心头。
【论】夫自汗者，朝夕汗自出也。盗汗者，睡而出，觉而收，如寇盗然，故以名之，阴虚火盛也。然心之
所藏，在内为血，发出为汗，故汗为心液，所以自汗之证，未有不由心虚而动之也。亦有阳虚气弱自汗者，此
卫气不能固敛也。有湿盛自汗者，有表虚自汗者，有痰证自汗者，有火气上熏胃中湿而自汗者，种种不同，各
因其证而治之。盗汗由于阴虚血弱，常补阴降火益气自愈。若别处无汗，独心孔有汗者，名曰心汗，由思虑多
而得，故其病在心，治之宜养心血而汗自止矣。
【脉】汗脉浮虚，或濡或涩。自汗在寸，盗汗在尺。

[Verse]
Exterior deficiency and blood weakness cause sweat to flow like water; dampness syndromes drip incessantly without ceasing. Phlegm syndromes cause moisture to constantly soak the back; collapse of Yang Qi and depletion causes sweat to be like oil. Yin deficiency with night sweats is accompanied by blood deficiency; sweat soaks the bedding during deep sleep and stops upon waking. Heart sweating is generally caused by excessive thinking, feeling as if a round patch exists in the heart center.
[Dissertation]
Spontaneous sweating refers to sweat flowing out naturally morning and evening. Night sweating refers to sweating during sleep and stopping upon waking, acting like a thief, hence the name; it is due to Yin deficiency with hyperactive fire. The Heart stores blood internally and manifests as sweat externally; therefore, sweat is the fluid of the Heart. Thus, spontaneous sweating syndromes are invariably triggered by Heart Qi deficiency. There are also cases of spontaneous sweating due to Yang deficiency and Qi weakness, where Wei Qi (Defensive Qi) fails to consolidate and retain. There are cases due to excess Dampness, exterior deficiency, phlegm syndromes, and fire qi steaming upward into stomachal dampness. These vary greatly and should be treated according to the specific syndrome. Night sweating results from Yin deficiency and blood weakness; usually, tonifying Yin, descending fire, and benefiting Qi will lead to self-healing. If there is no sweat elsewhere on the body but only at the heart orifice, it is called Heart Sweating, caused by excessive mental exertion. The pathology lies in the Heart; treatment should nourish Heart Blood, and the sweat will stop spontaneously.
