The incidence of day lily poisoning is seasonal and regional, mostly sporadic, and the incidence rate is high.

Causes of day lily poisoning

Fresh day lilies contain colchicine chemicals. Although colchicine itself is non-toxic, it can be oxidized into colchicine during metabolism after gastrointestinal absorption, and it is a highly toxic substance. Adults who ingest 0. 1-0.2 mg colchicine at a time (equivalent to eating 50- 100 g of fresh daylily) may have poisoning symptoms within 0.5-4 hours. If the intake reaches more than 3 mg at a time, it will lead to serious poisoning and even death.

Manifestations of day lily poisoning

Symptoms such as dry throat, thirst, nausea, vomiting, abdominal pain, diarrhea and so on. In severe cases, bloody stool, hematuria and even death may occur.

Preventive measures of day lily poisoning

1) Don't eat too much at a time, generally not more than 50 grams;

2) Because colchicine is soluble in water, it must be soaked in water for more than two hours before eating, or scalded with boiling water to remove colchicine from the juice, and it must be fried thoroughly before eating.
