According to experts, fresh day lily contains a substance called colchicine. After the oxidized colchicine enters the human body, it has a strong stimulating effect on the gastrointestinal tract and respiratory system of the human body, which can cause toxic symptoms such as abdominal pain, diarrhea and vomiting. Therefore, fresh daylily must be treated with colchicine removal before eating. Because colchicine is water-soluble, fresh daylily can be blanched with boiling water, then fully soaked and washed with clear water, so that colchicine can be dissolved in water to the greatest extent, and then cooked, which can ensure food safety. After eating fresh day lily, once you have symptoms such as vomiting and diarrhea, don't panic and go to a regular hospital as soon as possible. At the same time, you can also use simple methods to induce vomiting and reduce the absorption of toxic substances, but don't take the medicine yourself, so as not to aggravate the condition.

Dried daylily has no toxin, but if it is moldy due to improper storage, it is another matter.
