I went to the drugstore to buy ordinary astragalus before, but the clerk said that ordinary astragalus would not soak, and it would take at least 20 minutes to cook. I made a decisive decision. Then he recommended Cao Jinghua's broken-wall astragalus root, which can be brewed directly in a few seconds, which is very suitable for us busy office workers and can also be directly poured into mineral water bottles to drink. I think this is their biggest difference.
