Hmm...interesting. Both my sister and I are allergic to sulfa drugs but have never been told to look out for other things, plants, etc. And I don't recall any prpblems that might be traced to the plants. The only reason I know about the Celebrex and Bextra connection is because my doctor told me I had to take Vioxx because of the allergy. Doing reseach, I found that to be the case. Of course, this was several years back when they all were on the market. And I was only told that some antibiotics had sulfa in them and that I should be careful about them (as well as anything in the penicillin, tetracycline and mycin groups as I am allergic to them as well). What else should I be on the watch for?
