Hasseltrær er tidlige blomstrere som markerer starten på allergisesongen for mange. Deres hanrakler slipper ut store mengder pollen så tidlig som vinter eller vår, noe som kan utløse betydelige allergiske reaksjoner hos personer som er følsomme for trepollen.

If you develop allergy symptoms such as sneezing or itchy eyes early in the year, coinciding with hazel trees’ pollination, you might want to consider allergy testing.
Hazel pollen is allergenic because it contains proteins that can trigger an immune system response in people who are sensitive, leading to the symptoms of allergic rhinitis.
Managing hazel allergy symptoms includes staying indoors on days with high pollen counts, using air purifiers at home, and following medical advice for allergy medications.
