ORAL ALLERGY SYNDROME
This syndrome is now more commonly called Pollen Food Allergy Syndrome (PFAS)
- the term "Oral Allergy" has been adopted to define the symptoms of the syndrome.
Sufferers of Oral Allergy are usually people who already suffer from pollen allergies and seasonal rhinitis and this is due to cross reactivity.
