Members of the family Anacardiaceae cause more cases of allergic contact dermatitis than those of all other plant families combined. Most allergenic family members belong to the genus Toxicodendron, and they possess a toxic oleoresin called urushiol. Rhus is the largest genus in the family Anacardiaceae, but it does not contain the allergenic plants, most of which belong to the genus Toxicodendron.
