An allergy refers to an exaggerated reaction by our immune system in response to bodily contact with a foreign substance. Allergy-producing substances are called "allergens." Examples of allergens include pollen, dust mite, mould, danders and food. 
Common allergic conditions include hay fever, asthma, allergic eczema, hives, allergic eyes and allergic rhinitis.
