WILLOW TREE POLLEN ALLERGY
Willow trees are in the Salicaceae family of plants. Other plants in this family include poplar and aspen trees.
The sap in willow trees is high in salicylic acid, which can cause contact allergic dermatitis.
Willow trees are insect rather than wind pollinated, so even though the pollen is highly allergenic you would have to be close to the trees for it to have an effect.
The pollen season for Willow is February to April peaking in March.
An allergy to willow tree pollen is strongly associated with seasonal allergic rhinitis (hayfever).
A willow tree pollen allergy is also linked to asthma, rhinoconjunctivitis and atopic dermatitis.
Other plants in the Salicaceae
family of plants include poplar and aspen trees. If you are allergic to the pollen of these plants, you may also want to avoid willow trees.
