Celery is a frequent food allergen: not only raw, but also cooked and as a spice it can produce various reactions of immediate type, from oral contact urticaria to @entity2021 . Most celery-allergic @entity1 suffer from @entity2023 and show a skin sensitization to mugwort. An associated @entity566 to several spices is quite common, and therefore the term "celery-mugwort-spice-syndrome" has been proposed. The authors have investigated 35 @entity1 , 85% of them @entity1 , in whom a current celery @entity566 of varying severity was diagnosed during the first 8 months of 1984. A positive skin test to celery was seen in 16 @entity1 who denied any symptoms from it. Thorough skin testing and RAST screening with different celery preparations, other foodstuffs and mugwort-pollens were performed on all @entity1 . The modified prick test with native celery-root proved to be the best method for detecting celery sensitization, showing a positive result in 88.6%. The scratch test with celery-salt was positive in 70.5%, intracutaneous testing with commercial extract in 63.5% and the RAST with celery-sticks in 66% of the @entity1 . Sensitization to mugwort was absent in 8 @entity1 only. The mugwort-sensitive group frequently showed a positive test to ragweed-pollens, a common plant in North America, and this appears to indicate cross-reactivity amongst the family of the Asteraceae. Cross-reactivity amongst the Apiaceae is the cause of the many positive results obtained with @entity10786 , parsely, anise, fennel and caraway, the @entity10786 @entity566 being of clinical importance in 50% of cases, including one with a history of @entity2021 after ingestion of raw @entity10786 .(ABSTRACT TRUNCATED AT 250 WORDS)
