Fireweed/Great Willow Herb

What is Fireweed?

Fireweed (Chamaenerion angustifolium), also known as a great willow herb, is a tall perennial plant with striking purple flowers. It is commonly found in disturbed soils, such as burned areas or along roadsides, and blooms in late summer. Its lightweight pollen can become airborne and cause allergies in some individuals.

Why do I have an intolerance?

People with an intolerance to fireweed pollen experience allergic reactions when the immune system identifies its proteins as harmful. This causes typical allergy symptoms like sneezing, itchy eyes, nasal congestion, and in some cases, respiratory irritation. Fireweed pollen is often found in areas with high concentrations of plants, like meadows or roadsides.

What can I do about it?

To manage symptoms, avoid areas with abundant fireweed, particularly during its blooming season in late summer. Wearing protective gear, such as a mask, while outdoors can help reduce pollen exposure. Indoors, keeping windows closed and using an air purifier can also help minimize pollen levels.
