Is the jacaranda tree toxic to children and pets?

Yes, the jacaranda tree can be toxic to children and pets. The Food and Drug Administration includes the tree in its database of toxic plants even though sources such as the American Society for Protection Against Cruelty to Animals (APSCA) and studies such as by the University of Hawaii indicate otherwise. The Mountain Woodworker keeps a list of woods that are toxic to woodworkers, and the jacaranda tree shows up as provoking Asthma and dermatitis.
