Zi phlegm is the name of the disease in Chinese medicine, which is equivalent to epididymal tuberculosis diagnosed in Western medicine. The reason why it is called Zi Phlegm is that Zi refers to kidney, i.e. testis or epididymis, which indicates the location of the disease; Phlegm refers to the pus coming out from the localized mass of kidney which breaks down at the onset of the disease, which is clear and dilute in quantity, with fishy smell, similar to phlegm, so the disease is called Zi Phlegm. In the early stages of the disease, the scrotum will be conscious of the obvious feeling of swelling, can be touched in the epididymis or vas deferens nodules, hard, long time after the abscess breaks down before the pus will flow out of the fishy pus. According to Chinese medicine, the cause of the disease is deficiency of qi and yin, accompanied by hot flashes, night sweats, irritable fever, pale face, sleepy limbs, etc. Modern medicine is tuberculosis bacillus infection of the lungs, kidneys and other parts of the lungs and kidneys, which are transferred to the testicles or epididymis, so it is recommended to give anti-tuberculosis treatment, together with the internal use of traditional Chinese medicine, to improve the systemic symptoms.
