The sensitization potency is moderate, the frequency rare. There are case reports on allergic reactions. Cross reactions with yarrow, German chamomile, lettuce and chrysanthemum have been experimentally observed. Occasionally, a positive reaction to Roman chamomile has been seen in individuals allergic to composites.

One case of anaphylactic shock after ingestion of Roman chamomile tea has been observed. The occurrence of rhinitis is possible in individuals with atopic allergy to mugwort.
