The symptoms of prostatitis are related to stranguria (stranguria caused by ointment, stranguria caused by fatigue and stranguria caused by qi), turbidity (white turbidity, red turbidity and fine turbidity), lumbago due to kidney deficiency, impotence, nocturnal emission and masturbation. One of the typical symptoms of prostatitis is white secretion dripping from urethra, which is called white turbidity or fine turbidity in traditional Chinese medicine. It can be seen that prostatitis is a fine disease, and the disease is located in the kidney. At first, it was mostly heat syndrome, but over time it was mostly deficiency syndrome. The fire of young and middle-aged people is on the high side, and the damp heat is on the high side, which disturbs the seminal vesicle, confuses the essence and turbidity, and the essence and qi are out of position, resulting in this disease, which is mostly manifested as acute prostatitis or acute attack of chronic prostatitis. After a long time, damp heat hurts the spleen and stomach, the spleen sinks, and the deficiency of kidney essence is exposed. This is the general process of the disease from excess to deficiency. Prostatitis is mostly caused by kidney deficiency, and because the kidney stores essence, the essence and turbidity damage the kidney, while kidney deficiency is mostly caused by kidney yin deficiency. Damp-heat is the standard, kidney deficiency is the foundation, blood stasis is the further pathological reflection of entering the chronic process, and deficiency in the middle is the inevitable result of spleen injury caused by damp-heat. Of course, it may also be related to spleen deficiency in the body, or caused by kidney deficiency invading the spleen.
