General poisoning notes:

Angel's trumpet (Datura innoxia) contains toxic alkaloids that have caused poisoning and death in humans and other animals. Most of the literature concerns poisoning by jimsonweed (Datura stramonium), but angel''s trumpet should be considered poisonous as well. This plant is occasionally grown as an outdoor ornamental herb because of its spectacular tubular flowers. See additional information under general notes of Datura stramonium.
