Pollen not active in Sevan

Pollen contains proteins that cause an allergic reaction in people. These proteins can trigger the immune system's defense mechanism because they're perceived as an external threat, even though in reality they're harmless. The antibodies produced in an attempt to fight the perceived danger are what causes allergy symptoms.

Poplar-seed allergies are rare. Most reactions people have when exposed to poplar seeds aren't caused by the seeds themselves, but by the pollen they carry. Poplar seed fluff is in the air at the same time as pollen from many other plants, so people may think they're allergic to poplar seed fluff when they're not.
