1. Blanch the daylily with boiling water first, then soak it in cold water for a while, then take it out and drain it, and then put it in the sun. Fresh daylily contains slightly toxic colchicine, which is easy to decompose when heated and dissolve in cold water, so choose to dry it in a stable sun day, preferably on the cement floor, instead of using some absorbent bamboo frames.

2. Daylily can only be eaten when it is dried in the sun. Fresh daylily contains colchicine, which is a trace toxin, which can make people slightly poisoned. Therefore, the fresh daylily should be boiled with boiling water first, and then soaked for a period of time to filter out the toxin. Dry daylily should be kept away from wet places and sealed. Check whether the dried daylily is moldy once a week, and sprinkle some powder when it is stored for a long time.
