Abstract
Celery [Apium] and parsley were confirmed as etiological agents in 14 patients with severe attacks of angioedema and urticaria. All of the patients were atopic. Without exception they all had positive prick test reactions to mugwort. The patients were examined using the scratch - chamber test method and all of them showed positive reactions to celery and 12 patients to parsley. No peroral provocation tests were performed because of the severity of the reactions in the past. Passive transfer by the Prausnitz-Kuestner technique was positive in 2 patients.
