Latex – Allergy Resources

Latex is a product of the rubber tree, Hevea brasiliensis , it has 15 associated contact allergens.

Hev b 6 is a hevein precursor protein, this allergen is important in cross reactivity.

Hev b 7 is a patatin protein, again important in cross reactivity.

Hev b 8 is a profilin profilin, these are panallergens found in many plants and foods.

Hev b 11 is a chitinase, these are proteins found in other foods and contribute to cross reactivity of latex.

Hev b 12 is a lipid transfer protein (LTP) this is another panallergen and cause problems over multiple foods and plants.

An allergy to latex may give you the potential to be allergic to many foods and pollens, but you may only have contact issues with latex itself.

Latex is often associated with Latex Food Syndrome. This is where the body is initially sensitised to the latex plant and later becomes allergic to foods which contain similarly shaped proteins.

Latex contains LTPs, this can link it to LTP Syndrome, where LTPs in multiple plants and foods cause allergic reactions.

I have put together some more comprehensive resources at

The allergy resources page for latex covers the key allergens, which allergic syndromes are linked to this allergy and other foods which are commonly cross reactive with latex.

There is also regularly updated links to useful websites specifically for latex 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.

I love to write about food allergies, asthma and eczema.
