Diarrhea after taking Zhi Bai Di Huang Wan is not normal and is a side effect of Zhi Bai Di Huang Wan. The main reason is that Zhi Bai Di Huang Wan is based on the Six-flavored Di Huang Wan, adding Zhi Mu and Huang Bai, both of which are yin nourishing drugs with a certain degree of coldness. Therefore, the body is weak, especially the spleen, stomach weak patients and patients with poor gastrointestinal function, after taking it will cause diarrhea and other phenomena. At this time, you need to stop using Zhi Bai Di Huang Wan, and you can also take ginger water or tonic Zhong Yi Qi Pills, plus the spleen and intestines pills and other drugs to regulate.
