Fenugreek (also known as methi) is a seed used to flavour food. It is a legume and there has been research to show some cross reactivity with other legumes including peanuts and soya beans.
Fenugreek contains 2S, 7S and 11S seed storage proteins as well as PR-10 plant pollen proteins.
I have put together some more comprehensive resources at http://www.allergyresources.co.uk/Fenugreek.php
The allergy resources page for fenugreek covers the key allergens, which allergic syndromes are linked to this allergy and other foods which are commonly cross reactive with fenugreek .
There is also regularly updated links to useful websites specifically for fenugreek 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.
