Common stimuli or allergens are pollens, mold, house dust mites, animal dander, and insects (Allernet, 1999). These normal substances stimulate the body to release immunoglobin E (IgE) antibodies that are involved in the recognition of these allergens. IgE antibodies on the surface of mast cells are the primary cause of allergies; it is know that these IgE antibodies originated in the body to kill off parasites.
