Why it's dangerous
Daffodils contain lycorine, an alkaloid with strong emetic properties, and crystals in the bulbs that cause severe tissue irritation and secondary drooling.
Toxic compound: Lycorine
Good to know
Ingestion of the bulb is particularly dangerous as it contains concentrated crystals and can lead to more severe symptoms.
