I have a mild allergy to Onions, Garlic, Shallots, etc. - all members of the genus Allium. Is there a noun I can use to readily describe all these? Eg: "I have a(n) _____ allergy."
Been thinking about it for a while, and it seems kind of tricky. I can't say "I have an Allium allergy" because that implies Allium is an entity, a thing to be allergic to. Onions don't contain Allium any more than John contains Smiths.
Based on a related question, I could say "I have an allergy to Alliaceous plants", but that seems like a bit of a mouthful. I'd love to find something a little more elegant/fluid if possible!
