Many people suffer from nasal allergies or called hay fever around spring and fall time. Some of them even have symptoms year around. In medical term, it called allergic rhinitis. Allergic rhinitis occur when the body’s immune system overreacts to particles ( allergens ) in the air that people breathe in. Those allergens include pollen, dust, animal fur, and mold. When those allergens enter into our body through breathing, our body’s immune system-white blood cells will produce antibodies like IgE, these antibodies will make the release of histamine by mast cells. Histamine will cause the muscle spasm of the respiratory tract which includes the nasal, ear and eye and people will have running nose, sneeze, watery eye, itchy ear, nose, throat and eye.
