Human body is sensitive to some of the substances around it. Allergy is the changed reaction of the body that occurs after exposure to certain substances known as allergen or antigen. Such allergic reaction causes pathological changes and disturbances of function in the tissue where the reaction occurs. Allergic rhinitis, bronchial asthma, bronchopulmonory eosinophilia are some of the common conditions that disturb the respiratory tract due to allergy.
