Q: I always feel depressed recently, and I can't sleep well at night. I always feel backache at the end of the day. My wife said that I may have kidney deficiency, and I don't know if it is kidney deficiency. So I would like to ask what the symptoms of male kidney deficiency are, and look at a Chinese Shengbao Guyuan tea. Is this tea effective in conditioning kidney deficiency? A: From the above description, you do have kidney deficiency. Nowadays, working pressure, staying up too late and smoking too much will lead to kidney deficiency in men. Don't be too nervous when you have kidney deficiency. Usually pay attention to conditioning, eat more kidney-tonifying foods such as walnuts, yams and sea cucumbers, but don't abuse some kidney-tonifying drugs. A little carelessness will backfire. I have seen one of my colleagues drink this China Shengbao Guyuan tea before. At that time, he was seriously deficient in kidney. After drinking this tea for about three months, his kidney deficiency has obviously improved. Although I have never tasted this kind of tea, according to my colleagues, the effect is still very good. You can try.
