Aspen

What is Aspen?

Aspen trees (Populus tremuloides) are deciduous trees known for their tall, slender trunks with smooth, white bark that often has dark knots. Aspen trees are native to North America and parts of Europe and are commonly found in cooler climates. The trees are famous for their quaking leaves, which flutter in the wind. Aspen trees produce catkins, releasing pollen during the spring to pollinate other trees.

Why do I have an intolerance?

Aspen pollen is a well-known allergen that can trigger allergic rhinitis and asthma in sensitive individuals. Those with pollen allergies, particularly tree pollen, may experience symptoms like sneezing, nasal congestion, and itchy eyes. Additionally, people with oral allergy syndrome may experience tingling or swelling of the mouth or throat when consuming fruits like apples or pears, which share proteins with aspen pollen.

What can I do about it?

To reduce exposure to aspen pollen, avoid outdoor activities during peak pollen season, typically in early spring. Keeping windows closed at home and using an air purifier can help filter pollen indoors. Wearing protective clothing and a mask while outdoors can also minimize exposure.
