DefinitionThis section has been translated automatically.
19-25% of pollinators in Central Europe are sensitized to birch pollen (see below pollen; see below tree pollen). Birch pollen allergy sufferers react particularly frequently (30-70%) to food (see cross-reaction below). The most frequent cross allergies are to stone and pome fruit (especially apple; see below apple allergy), soya (Gly m4), nuts, raw vegetables (especially carrots), celery (Api g1), less frequently to Brazil nuts and peppers.
These food allergies often manifest themselves as " oral allergy syndrome". In rare cases, birch pollen allergy sufferers develop contact urticaria caused by birch branches. A worsening of atopic eczema (freely carried skin areas) associated with birch pollen is questionable.

According to the IUIS Allergen Nomenclature Sub-Committee 6 birch pollen allergens are officially accepted to date:
- Bet v 1 Pathogenesis-related protein (PR-10 protein: major allergen)
- Bet v 2 Profilin: Minor allergen
- Bet v 3 Polcalcine-like protein
- Bet v 4 Polcalcin: Minor allergen, indicator of cross-reactivity with other Pocalcininenin tree, grass and herb pollen.
- Bet v 6 Phenylcoumarin-benzylether reductase
