title: [Contact urticaria caused by Peru balsam].
abstract: By tests on six patients with recurrent urticaria it could be demonstrated that it was caused by an allergy against Peru balsam. Different reaction types seem to have been responsible for the occurrence of the urticaria. Cross reactions with different other substances, mainly luxury food and stimulants, play a particular part.
