If you don't blanch these 6 types of food, you could be in danger!

Fresh daylily
Daylilies have a long history in Chinese cuisine, and they frequently appear on people's tables, especially in summer. Whether served cold, stir-fried, or stewed in soup, daylilies can add a touch of freshness and crispness to dishes.
However, fresh daylilies contain a toxin called colchicine, which can be harmful to the human body if left untreated.
Colchicine is a toxic chemical substance to humans. If fresh daylilies are not blanched before consumption, these toxins can enter the body and cause poisoning.
Symptoms of daylily poisoning include vomiting, abdominal pain, and liver and kidney damage. In severe cases, it can even lead to death.
Therefore, fresh daylily must be thoroughly blanched before consumption, and the blanching water must be discarded.
After this treatment, most of the colchicine in daylilies will be removed, making them safe to eat while preserving their delicate flavor.
