Alder

What is Alder?

Alder trees (genus Alnus) are medium-sized, deciduous trees found in northern temperate regions, especially near rivers and wetlands. These trees are easily recognizable by their serrated leaves, gray bark, and clusters of small, cone-like fruits called strobiles. This makes them valuable for ecological restoration and land stabilization projects. Alder wood is used in furniture making, smoking meats, and even in musical instruments.

Why do I have an intolerance?

Alder trees release large amounts of pollen during their early spring blooming season. This pollen can be a potent allergen, causing symptoms like sneezing, nasal congestion, itchy eyes, and even respiratory discomfort in sensitive individuals. People who are allergic to birch pollen may also react to alder pollen due to cross-reactivity, as both trees share similar proteins that can trigger allergies.

What can I do about it?

If you’re sensitive to alder pollen, avoid outdoor activities near alder trees during their blooming season. Keeping windows closed and using an air purifier indoors can help minimize pollen exposure. Wearing a pollen mask outdoors and showering after being outside can also reduce the chances of a reaction.
