Yes, you can. My dad has high blood sugar, and he eats metformin every day to maintain his blood sugar, so his blood sugar is still at 15 16. I gave him Jianpi Yi Sheng Pill for two weeks, and it recovered to 1 1 and 12 after just two weeks. It's been almost three months, but it's still at 7, 8. After that, the dosage of metformin decreased.
