There are quite a lot of medicines to replenish the kidney, but the better one, I think, is the eight son of the kidney capsule, it is a kind of specialized in the deficiency of kidney essence to replenish the kidney nourishing nourishing traditional Chinese medicine. Because it contains 8 subtypes of Chinese medicine, so it is called "eight son tonic kidney". It can be used for soreness of the waist and knees, dizziness, tinnitus, fatigue and forgetfulness, fatigue and weakness, coldness and cold limbs due to insufficiency of kidney and yang. It has the effect of tonifying the kidneys and warming the yang. My friend has taken it before and the effect looks quite good. Kidney deficiency can easily cause kidney disease, or the earlier the treatment, the better.
