The best way to take it is to take Buzhong Yiqi Pill in the morning and noon, and Liuwei Dihuang Pill in the afternoon and evening. Better take them separately.

Liuwei Dihuang Pill tonifies the kidney and Buzhong Yiqi Pill tonifies the spleen and stomach. There is no conflict between the two drugs, but the therapeutic effect is a little worse when taken together. .
