Kidney deficiency is divided into yin deficiency and yang deficiency.1, kidney yin deficiency refers to the deficiency of kidney yin, the related tissues and organs are not nourished, the symptoms manifested by the deficiency of heat, and the main lumbar and knee soreness and pain, dizziness and tinnitus. Insomnia and dreaming, thinness, fever and night sweating, five heartburn, red tongue with little moss and so on. If this is the case, you can tonify the kidneys, nourish the yin and lower the fire. Eat six flavors of dihuang pill is better, 2. Kidney yang deficiency refers to the yuan yang deficiency decline, from warmth, reproduction, gasification function decline in the performance of symptoms. The main performance is the waist and knee soreness and cold pain, cold limbs, lower limbs, especially, the face of white, fatigue, libido frigidity, tongue coating white, pulse, etc..
