An allergen is a chemical that induces an allergic response despite its otherwise benign nature. Hay fever, also known as allergic rhinitis, is an allergic reaction to particular allergens. In seasonal allergic rhinitis, pollen is the most frequent allergen. These are allergy symptoms that appear when the seasons change.
