Hello! Friend, let me help you answer your question. Dog root is the so-called "seal kidney" in Chinese medicine, which is the reproductive organ of male dogs. Its main function is to warm kidney and strengthen yang. Generally, Chinese medicine shops basically sell them. One is probably 10 yuan. The specific processing method is as follows: after buying it, it is hard and delicious, cut into sections with a machete, then put some talcum powder in the wok, put the chopped dog whip in, gradually heat it, then bake it thoroughly and take it out to make noodles, with a spoonful of warm water each time. I hope I can help you, and I also urge other friends to criticize and correct me. Finally, good luck!
