Alder pollen

Alder pollen is a common windborne allergen in wooded areas of North America. The pollen can be found miles away from their source.

In some cases, people who are allergic to alder pollen can develop oral allergy symptoms when they eat certain fruits and vegetables. You may have this if you've noticed symptoms such as itchiness, swelling or redness after you've eaten a peach, apple, plum, celery or carrots.
