Only a handful of those allergies are on the usual allergy tests. I actually discovered the causes
through trial and error instead of an allergist. (Doesn't take a genius to figure out what a migraine, sneezing attack, hives, eczema, and asthma attack whenever I'm around lavender or lavender products means.)
Anyway if you're allergic reactions are severe (headaches/migraines, nausea, skin rashes) I suggest asking for a more extensive allergy test.
