Toxicity to pets
Jimson weed (Datura stramonium), which is also known as devil’s trumpet, thorn apple, Indian apple, black datura, jimsonweed, tolguacha, and Jamestown weed, is poisonous to pets (especially to large animals like horses, cattle). All parts of this plant are poisonous, as they contain the toxin tropane alkaloids (which is similar to the drug atropine). Ingestion results in dilated pupils, light sensitivity, restlessness, anxiousness, dryness of the mouth, intestinal stasis (lack of normal flow of intestinal contents), constipation, increased heart rate and breathing, walking drunk, and respiratory failure.
