The flowers of day lily contain colchicine, which is transformed into dioxcolchicine in human body, making people poisoned. Fresh daylily should be treated at a high temperature above 60℃ or soaked in cold water and boiled in boiling water for a long time to avoid poisoning. Long-term drying will also destroy colchicine.

Soak in water a few times before eating, and there will be no problem.
