Monarda plants are safe and non-toxic to animals and humans. Animals, especially dogs, are attracted to the aromatic scent of their colorful flowers and tend to roll around and rub against them. However, dogs will most likely not eat the leaves because they do not like the taste. Bee Balm is an ingredient in many herbal and holistic treatments and is used for medical applications for animals. Of course, too much ingestion of this plant could cause toxic reactions, and some symptoms include weakness, vomiting, diarrhea, drooling, etc.
