After the fresh day lily is steamed, it is exposed to the sun until it is dry, so the toxicity can be greatly reduced. In addition, soaking in warm water or clear water for half an hour before eating can completely avoid the harm of residual colchicine to human body. Even if you eat dried day lily, it is best to soak it in clear water for at least 30 minutes before eating. During this period, change the clear water several times, and then rinse it repeatedly before eating to remove the residual sulfur dioxide, which is safer.
However, the quality of dried daylily can be seen in the market is uneven. Some inferior day lilies are added with a lot of additives, and some are even smoked with sulfur. Therefore, we still don't choose this inferior day lily. When eating, you should first blanch the day lily with boiling water, then soak it in clear water for more than 2 hours, take it out and wash it with clear water before frying it, which will destroy colchicine and make it safe to eat the day lily.
Some people say that fresh day lily is not toxic when the stamens are removed, so it can be used safely. In fact, this practice is wrong. Although the colchicine content in stamens is higher than that in petals, the quality of stamens and petals of day lily is very different. After the colchicine in day lily reaches the stomach, it can strongly stimulate the digestive tract, causing acute poisoning, nausea, thirst, vomiting, diarrhea and other symptoms.
Day lily is a favorite delicacy for adults, because it is rich in protein, fat, carotene and multivitamins. Need to be reminded that "day lily is not fresh and dry", because day lily contains a small amount of colchicine, and its toxicity is reduced after processing and drying.
