Japonica, Bog Rosemary, Pieris, Pieris japonica
Toxicity to pets
Japonica, Bog Rosemary and Pieris species contain grayanotoxins (formally called andromedotoxin). Like the Rhododendrons (same family), ingestion of these plants cause a disruption in sodium channels affecting the cardiac and skeletal muscle. Clinical signs of excessive drooling, depression, weakness, vomiting, diarrhea, heart arrhythmias, hypotension (drop in blood pressure), and death can occur when ingested by dogs and cats.
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.
