Allergen
The pollen is a known allergen, although not as potent as that of the related Juniperus ashei (Ashe juniper), which sheds pollen a month earlier. People allergic to one are usually allergic to both. J. virginiana sheds pollen as early as late winter and through early spring. Consequently, what begins as an allergy to Ashe juniper in the winter, may extend into spring, since the pollination of the eastern juniper follows after that of the Ashe juniper.
Contact with the leaves or wood can produce a mild skin rash in some individuals.
