Allergen,Individual-Tree pollen Birch Betula Verrucosa

Birch belongs to the Betulaceae family and its pollen is considered as the major cause of allergy due to tree pollen. There is cross-reactive allergy between the pollens of the different Betulaceae species (alder, hazel, and birch). Therefore, individuals allergic to birch pollen may also experience allergy symptoms at the beginning of the year when the concentrations of alder and hazel pollens are very high. Some individuals sensitized to birch pollen may experience cross-reactive allergy with some foodstuffs (apples, cherries, almonds, hazelnuts, kiwis). Consumption of these raw fruits may cause symptoms such as pruritus and mouth swelling.

An allergy to Birch (Betula verrucosa) triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.
