The oral allergy syndrome

Abstract

We have studied 262 patients suffering from hay fever and oral allergy syndrome after fruit and vegetable ingestion. The history and the results of RAST and skin test for pollen showed a contemporary presence of systemic and local symptoms in most of the patients; a close connection between age of onset of hay fever and oral allergy syndrome; a frequent association between allergy to some pollens and some vegetables, such as between apple, carrot, pear, cherry with birch pollen and tomato, melon, watermelon with grass pollen.
