Tonifying kidney can start from diet, daily life and health care. In dietotherapy, you can eat more yam, Euryale ferox, medlar, chestnut and other foods. The method of making these foods is very simple. Yam can be steamed in a pot, and some can be put when you cook porridge. When you cook porridge and soup, you can put some or brew it directly. Insisting on taking it will have obvious effect of tonifying kidney and replenishing essence. You can also soak raw Cordyceps sinensis in water, which is more useful. Work and rest regularly in life, don't stay up late, get enough sleep every day and keep your mood comfortable and stable. Pressing Yongquan point on the sole of the foot every day and doing ginger moxibustion at Shenshu point once a week will have obvious kidney-tonifying effect for a long time.
