Japanese Cedar Tree

What is Japanese Cedar Tree?

The Japanese cedar tree, or Cryptomeria japonica, is a coniferous tree native to Japan but also found in other parts of Asia and increasingly in temperate regions worldwide. It has needle-like leaves and produces large amounts of pollen during its flowering season, which typically occurs in early spring. The pollen is airborne and can travel long distances, making it a common allergen in areas with large populations of these trees.


Why do I have an intolerance?

Intolerance to Japanese cedar pollen occurs because the immune system mistakenly identifies its proteins as harmful. This leads to the release of histamines, resulting in allergic reactions such as sneezing, itchy eyes, runny nose, and asthma in some cases. Individuals with tree pollen sensitivities are more likely to develop an allergy to Japanese cedar.


What can I do about it?

To reduce symptoms, avoid areas where Japanese cedars are abundant, especially during their pollen season in early spring. Keep windows closed during peak pollen times and use air purifiers indoors. If you're exposed to cedar pollen, wash your face, hands, and hair to remove pollen from your skin and hair, and change into clean clothes to minimize further exposure.
