Birch

What is Birch?

The birch tree (Betula spp.) is a deciduous tree known for its smooth, white bark and triangular leaves. It is commonly found in temperate regions and is especially prevalent in Northern Europe and North America. Birch trees are valued for their wood, which is used in furniture making and as firewood, and they also have ornamental value due to their striking bark. Birch trees produce catkins, which are their flower clusters, and release significant amounts of pollen in the spring.

Why do I have an intolerance?

Birch tree pollen is one of the most common allergens, particularly during spring when the trees bloom. The pollen can trigger symptoms such as sneezing, runny nose, itchy eyes, and even asthma in sensitive individuals. People with oral allergy syndrome (OAS) may also experience itching or swelling in the mouth and throat after consuming certain fruits like apples, cherries, and peaches, as these fruits contain proteins similar to birch pollen.

What can I do about it?

During birch pollen season, limit outdoor activities and keep windows closed to reduce pollen exposure indoors. Wearing a pollen mask or using antihistamines can help manage symptoms. If you have OAS, avoid consuming raw fruits that may cross-react with birch pollen.
