RESUMO
In the Huang di nei jing(Huangdi's Internal Classic), jin ye (fluid and humor) is described in two senses, broad and narrow, though not so strictly.Sometimes, jin ye is explained ambiguously as "sweat" and "urine" , as in the phrase "the bladder, being a house of jin ye" , here "jin ye" refers to the urine. In the Qi jue lun pian of Su wen (Chapter on Qi-Syncope of Plain Questions) , the "bao" in the sentence "heat of bao moved to bladder" refersto the uterus. In the Shi cong rong lun pian (Chapter of Readily Inspecting) of Plain Questions, the "bladder" in the phrase "gallbladder, stomach, large intestine, small intestine, spleen, bao and bladder" , which, being an annotation of "bao" originally, is mistakenly incorporated into the text of the Classic. In the Wu wei lun of Ling shu (On Five Tastes in Miraculous Pivot) , the "bao" in "bao of bladder" refers to the external hou (external manifestation) of the bladder, that is the scrotum. In the Bei ji qian jin yao fang (Essential Prescriptions Worth a Thousand Gold for Emergencies) , the short sentence "pang guang zou bao" is an error in itself. In the sentence of "settled in the bao and zhi causing to dream of defecation and urination" in the Yin xie fa meng (Dreams due to Evils) of Miraculous Pivot, "bao" refers to uterus, and "zhi" to anus. In Bi lun pian(Chapter on Impediment) of Plain Questions, "the man suffered bao bimight feel internal pain when the lesser abdomen and bladder are pressed" , here, "bao" refers to the bladder. In the Wu yin wu wei(Chapter on Five Sound and Five Tastes) of Miraculous Pivot, the "bao" in the sentence "thoroughfare vessel and conception vessel all starts from bao" , again, "bao" here refers to the bladder, rather than to the uterus. From the above descriptions of "bladder" and "bao" in the Huangdi's Internal Classic, the "bladder" in ancient medical books refers to the substantial bladder, an anatomical organ, and "bao" refers to cystiform organs, including the bladder, uterus, scrotum etc.
