Aller-defense

If youa re the kind of person who starts sneezing when you even think aboutspring flowers, ragweed, dust, mold or pet dander, chances are you have an immune system that over-reacts to harmless natural substances. Instead of reserving its immune response for viruses and bacteria, your body sounds a false alarm when exposed to a certain food or even a blade of grass a and rallies the immune system to attack. Sneezing, nasal congestion and itchy, water eyes a as well as the indigestion, swelling or skin rashes that food or chemical allergies can produce a are the all too- familiar results.
