Hello, whether the medicine is roasted or not depends on the condition. Choose different accessories according to the condition, generally using honey or salt or not. Roasting is to put the fragrant auxiliary materials in a clay pot (not metal) and fry them. Just like cooking, you can smell the fragrance, or you can fry them without auxiliary materials. Generally speaking, Cyperus rotundus can be fried with honey or dry fried for promoting qi circulation, relieving depression and relieving pain.
