Aniseed is a spice native to the eastern Mediterranean region. Cases of simultaneous hypersensitivity to celery, mugwort pollen, and spices of the Umbelliferae family have been described as the celery-mugwort-spices syndrome. We report a case of aniseed-induced tongue angioedema. Skin prick tests to foods proved positive only to aniseed. Serum-specific immunoglobulin (Ig) E determination by enzyme allergosorbent test was 0.4 kU/L to aniseed extract and 0.6 kU/L to tare and cumin seeds. The

This is the first case of type I hypersensitivity due to aniseed liqueur ingestion reported. SDS-PAGE immunoblotting study showed a broad specific IgE-binding band of 12.9-13.7 kd when aniseed extract was incubated with the patient's serum; this band might correspond to the protein responsible for the described symptoms.
