Beech trees are commonly found across Europe, but less so in the UK, where they are most often found in Wales and the South East of England.
There is 1 allergen associated with beech tree pollen, Fag s 1. It is an allergen associated with airways.
Fag s 1 is a Bet v 1 allergen, which means people suffering from this particular allergen may also be allergic to the pollen from birch trees.
Beech pollen occurs in the UK between March and May. This varies in different countries. It is considered to have low allergenicity.
I have put together some more comprehensive resources at http://www.allergyresources.co.uk/Beech.php
The allergy resources page for beech pollen covers the key allergens, which allergic syndromes are linked to this allergy and other foods which are commonly cross reactive with beech pollen.
There is also regularly updated links to useful websites specifically for beech pollen allergies and the latest research papers on the topic.
If you have multiple allergies and are interested in how they are linked or want to find out more about food allergies outside the usual top 14 then you can follow me on Facebook or Twitter, where I share a food allergy card every day of the week.
