How to grind angelica into powder?

Well, it can be mixed with other powders, and there will be no problem. If you need to crush Angelica separately: first, make sure Angelica is completely dry, and it is best to bake it in an oven at about 50 degrees for 3~4 hours, and then cut it into even small particles. Wrap in paper and freeze before crushing, and crush immediately after taking out. The maximum crushing speed is 10 second each time, and then the large particles are taken out by opening the cover, sieved, frozen again and crushed again. It's troublesome, and it's not easy to operate outside the laboratory.
