Allergy is defined as a "harmful, increased susceptibility to a specific substance," also known as hypersensitivity, while immunity is characterized as a "protective, enhanced resistance. An allergy is an abnormal reaction to ordinarily harmless substance or substances. These sensitizing substances, called allergens, may be inhaled, swallowed or come into contact with the skin. When an allergen is absorbed into the body it triggers white blood cells to produce IgE antibodies. These antibodies attach themselves to mast cells causing release of potent chemical mediators such as histamine, causing typical allergic symptoms. Some common allergens are pollen, mold spores, dust mites, animal dander, feathers, foods, medications, and insect stings. While there are many symptoms of allergy, watery, itchy eyes, sneezing, and a constant runny nose are some common symptoms.
