Eucalyptus is known as a potential cause of cutaneous diseases due to contact with oil or pollens, and of respiratory allergic diseases due to exposure to pollens. We report the case of a 30-year-old woman with asthma and rhinoconjunctivitis in which symptoms appeared to be exacerbated by Eucalyptus pollens and by ingestion of an infusion containing Eucalyptus. Specific IgE were positive for Eucalyptus pollens and negative for common aeroallergens. Our report shows that Eucalyptus may elicit asthma and rhinitis with an IgE-mediated mechanism both by inhalation of pollens and by ingestion of herb infusions, and suggests that care should be taken in administering herbal medications in asthmatic subjects.
