Salicylates are naturally occurring chemicals found in many foods including fruit skins, tea, spices, honey, ginger and some drinks.
There have been individual reports of salicylates causing allergy, although little research has been undertaken to support this. Indeed, standard blood tests used to diagnose allergy cannot be used to diagnose problems caused by salicylates.
There has also been a suggestion that salicylate intolerance could be responsible for some cases of irritable bowel syndrome, although once again we know of no published studies showing that avoiding salicylates will help people with this condition.
If you believe you suffer symptoms triggered by foods high in salicylates, this may be an intolerance, which is different to allergy.
It is important to get medical advice in order to find out whether salicylates really are responsible or whether there is some other trigger. See your GP in the first instance. It may be necessary for him or her to refer you to an allergy clinic.
