General poisoning notes:

Amaryllis (Amaryllis belladonna) is an ornamental plant commonly sold for its winter flowers. Ingesting the bulbs has poisoned humans. The toxic alkaloid, lycorine, is the principal toxin, although small quantities of related alkaloids are also present (Lampe and McCann 1985; Fuller and McClintock 1986).

Notes on Toxic plant chemicals:

Lycorine, a heat-stable alkaloid, is found in Amaryllis spp. as well as Clivia spp., Galanthus nivalis, and Narcissus spp. This chemical occurs in small quantities in Amaryllis species, so that large quantities of bulb must be eaten to cause symptoms (Lampe and McCann 1985).
