The fresh roots of Peony, which are used as medicinal herbs, will be piled up for 1 to 2 days in the room to make the moisture part evaporate and become soft. After removing the fibrous roots, the wood core will be withdrawn and dried to serve as the commercial paeonol. When the roots with poor skin color tend to be fresh, the rough skin is scraped off with a piece of glass or broken tiles, the wood heart is extracted, and the dried shavings are dried after being dried. The cut scallops were dried for Danshui.
