After drinking American ginseng, Lycium barbarum, Polygonatum sibiricum and Astragalus membranaceus for more than a year, I now have tinnitus and kidney deficiency. How come... Ask for an urgent answer Generally speaking, drinking the above four kinds of Chinese medicines will not cause the situation you mentioned. This mainly depends on daily life. I have met many people who think that they can get rid of it with the above drugs. In fact, the above four medicines are only used for daily health care, and their dosage is between health care and medicinal use. Although these four herbs all have yin and yang, we must pay attention to them in our daily life. As you said, because you provide less information for analysis, such as some other manifestations of the whole body, I suggest you go to a regular hospital for treatment.
