  • A single ragweed plant can release several million pollen grains per day, and just 5 grains per cubic metre of air is enough to trigger an allergic reaction2.
  • Grass allergy is responsible for more than half the cases of allergic rhinitis in Europe.3
  • Birch pollen allergy has tripled over the last 20 years4
  • Barely 15% of people who believe they suffer from pollen allergy have been diagnosed by an allergy specialist5.
