The primary culprit for allergy symptoms in Spring is tree pollen. Different types of tree pollen are released throughout the spring in the United States, depending on where you live.
Here are other types of common pollen allergy trees and plants known to produce allergic reactions in the U.S.
Cypress Tree Pollen
Cypress pollen is considered a severe allergen and is found, in large part, throughout the southwest part of the United States.
Aspen tree Pollen
The pollen from aspen trees is moderately allergenic and can be found throughout the United States.
Pollen from Hazel and Hornbeam Trees
The pollen from these trees is moderately allergenic and cross-reactive with the pollen of birch and alder trees as well as those in the chestnut family.
Pollen from Alder Trees
Alder trees shed pollen in large amounts during early spring. It acts as a primer, and can make allergy sufferers more sensitive to other pollen later in the season, especially birch.
Beech Tree Pollen
Beech tree pollen is mildly allergenic and can be found throughout the eastern United States.
Chestnut Tree Pollen
Chestnut tree pollen can be highly allergenic and is found throughout the eastern United States.
Ash Tree Pollen
Ash trees are found throughout the United States and their pollen is often severely allergenic. Because of their cross-reactivity, if you have an ash tree allergy, there’s a good chance you may be allergic to other olive species.
Privet Tree Pollen
Privet is a type of evergreen shrub that can grow to the size of a small-or medium-sized tree. It’s found throughout the United States and its pollen is often severely allergenic.
Juniper Tree Pollen
Juniper trees are found throughout the western United States. While most shed their pollen during spring, some can start as early as winter.
Cedar Tree Pollen
Cedar tree allergies—especially red cedar and mountain cedar—account for most cypress allergy cases.1 The most severe cedar pollen allergens are typically found in the eastern and southern part of the country.
There are other types of trees and plants with pollen that are allergic to humans. The aforementioned are the most common of them all.
Knowing the types of pollen allergy trees and plants can help you avoid them and live healthy without having to deal with the bad symptoms of pollen allergies.
