My one daughter is allergic to most everything! You may want to be tested for:
~tree allergies (cinnamon, nutmeg, maple syrup, nuts)
~bulb allergies (garlic, onions and Easter Lilies!)
~grass allergies (ragweed, hay fever, celery)
~molds (beer, most antibiotics, bread, wine, raisins, aged cheeses)
~commercial beef and chicken (animals are given antibiotics to keep them healthy)
~dust mites (washing linens in hot water and drying in a dryer helps this)
~insect droppings (many older homes have some evidence of insect invasion and the droppings can cause problems)
~aloe (and the darned stuff is in everything from lotion to shampoo!)
~Latex - she had to have her airbags in her car disconnected. A minor accident could kill her from the latex dust.
I can't think of any more just yet but I'll write more when I have time.
