Toxicity to pets
All parts of the Belladonna plant contain tropane alkaloids, including scopolamine. In the fall, the plant will produce shiny, black berries which can further entice pets and children. These alkaloids have anticholinergic properties which inhibit nerve impulses by blocking receptors in nerve cells causing hallucinations, depression, an elevated heart rate, and possible respiratory failure.
The content of this page is not veterinary advice. A number of factors (amount of substance ingested, size of the animal, allergies, etc.) determine what is toxic to a particular pet. If you think your pet has eaten something potentially toxic, call Pet Poison Helpline or seek immediate veterinary treatment.
