Lycorine is a toxic crystalline alkaloid found in various Amaryllidaceae species, such as the cultivated bush lily (Clivia miniata), surprise lilies (Lycoris), and daffodils (Narcissus). It may be highly poisonous, or even lethal, when ingested in certain quantities. Symptoms of lycorine toxicity are vomiting, diarrhea, and convulsions. Regardless, it is sometimes used medicinally, a reason why some groups may harvest the very popular Clivia miniata.
