The second tonic is velvet antler. Pilose antler has the effects of nourishing yin, strengthening yang, tonifying kidney and strengthening spleen. We can eat it ourselves or send it to our friends. I recommend a recipe, antler chicken soup. My wife used to make this soup for me when I was deficient in kidney. Then my body gradually recovered.
The last one introduces a very common tonic for tonifying kidney. It's walnuts. Walnut is rich in nutrition, which is of great benefit to backache, leg weakness, dizziness and tinnitus caused by kidney deficiency. Walnuts can be cooked with pork loin. Of course, you can also eat it raw and see your personal hobbies.
