Salicylates like histamines and other amines are naturally-occurring components of food. They can act on the nervous system brain an blood vessels. In people who are sensititive to these a wide range of symptoms (physical and/or psychological) can be experienced.
SALICYLATES are a family of plant chemicals found naturally in many fruits, vegetables, nuts, herbs and spices, jams, honey, yeast extracts, tea and coffee, juices, beer and wines. They are also present in flavourings (e.g. peppermint), perfumes, scented toiletries, eucalyptus oils, and some medications (ASPIRIN is a member of the salicylate family).
