ELM POLLEN ALLERGY
Elm trees are in the Ulmaceae family of plants.
They were not originally native to the UK and were most likely imported from the United States.
Elm pollen has moderate allergenicity and is found in cooler weather, between January and April depending on your location in the world.
Elm leaves produces sap which can cause contact dermatitis as they contain sesquiterpenes which are skin irritants.
An allergy to elm pollen is strongly associated with seasonal allergic rhinitis (hayfever).
An elm pollen allergy is also linked to asthma, rhinoconjunctivitis and atopic dermatitis.
There are currently no defined allergens for elm pollen, so no known cross reactivity.
