Oral allergy syndrome must be overseen in conjunction with the patient's other hypersensitivities, basically the sensitivity to dust. The side effect seriousness may wax and disappear with the dust levels. Patients are prompted to avoid the activating nourishments, especially nuts. Peeling or cooking the nourishments has been appeared to dispense with the impacts of a few allergens, but not others such as celery or strawberry. Immunotherapies with extracts are birch dust may advantage Oral allergy syndrome sufferers of hazelnut related to birch pollen allergens.
