The older name for this toxin was andromedotoxin. Disturbances in cardiac rate and rhythm may then be noted. If sufficient quantities were consumed, convulsions may occur, followed by coma and death. Not all affected animals will die, and livestock may recover without treatment, depending upon amount ingested. Prevent further ingestion and provide supportive care.
Veterinary attention is needed if ingestion was recent, or if clinical signs are present.
These plants are not safe in hay nor in any other prepared feed. Animals should not be allowed to graze these plants. Keep hungry livestock away from areas where these plants grow. Pets may nibble or taste the leaves out of curiosity or boredom, and this is not advised, but seldom leads to clinical toxicosis. Honey made from the nectar of these flowers is also toxic and should not be consumed, so exercise caution when placing beehives.
