Body reacts immunologically to non-immunogenic substances, which are also cause of the body state which is known as allergens. The first term come in the 1906, from Clemens von Pirguet, Viennese pediatrician. Symptoms and First Signs of Allergies The presence of the allergens may cause systemic or local inflammatory response. Substances which you can find anywhere not only in the home, but and spread, and which your body can not tolerate are known as allergens. If you are allergic on some of these allergens, the first contact with some of them, will overreact on your body. Actually, your immune system will produce more antibodies, to beat these substances.
