Background
Beech tar is used in insulation tape, tar paper, and topical medications. Rothenberg and Hjorth found that positive patch-test reactions to a mixture of wood tars consisting of pine, juniper, beech, and birch often produce false-positive reactions. When a mixture of wood tars is positive, each tar should be tested individually.
