I do remember reading about possible reaction to cabbage if allergic to sulfa. I would think a search with "sulfa and cabbage" in the search would yield results. I remember posting that I used cabbage for engorgement and I am very allergic to sulfa. No reaction. I also eat cabbage without difficulty. So I think it would be a rare reaction. However, I do ask moms about allergy to sulfa when recommending cabbage. I would recommend a patch test first, or an alternate therapy, or at the very least, to observe very closely for untoward response.
