Allergy to Ficus benjamina (weeping fig) in nonatopic subjects.

Occupational allergy to Ficus benjamina (Fb), or weeping fig, occurs in about one in four plant-keepers. Sensitization to this plant occurs in about 3-4% of persons with clear-cut atopy. I now report on four female nonatopic patients with rhinoconjunctivitis who were sensitized only to weeping fig. All four had a positive skin prick test and RAST test to Fb. The identification of a preventable respiratory allergen is of considerable importance for the patient. Inclusion of Fb in the standard prick test panel may therefore be considered. Furthermore, the findings suggest that it may be unwise to choose Fb as an ornamental indoor plant.
