Allergies 101
Allergy sufferers have immune systems that mean well, but are a little over-reactive, releasing chemicals like histamine to get rid of normally harmless substances called allergens.
Histamine triggers the body to push the allergens out, using your nose, eyes and mouth as exit routes, which creates inflammation and general allergy-related symptoms in the process.
