I often hear that Na Wei is healthy. What exactly does it do?

Na Wei is another magical medicine, which claims to be the best mineral supplement, but do you know that too many minerals are harmful to people? Excessive mineral supplementation can lead to kidney diseases, such as cysts and stones. I have seen a picture of so-called treatment of hypertension: a man over middle age is completely naked on his back and buttocks, and his back and buttocks are bleeding severely under the skin, all of which are bright red, indicating that his blood pressure has come down! If you have some knowledge of physics, you should laugh. This is equivalent to the container and liquid leaking, and the pressure will naturally come down, but how long can it last? Our hematopoietic function will be supplemented soon.
