Immunoglobulin E is an antibody, which is secreted from the white blood cell as a defense agent in our body. It helps us defending bacteria, viruses and other microorganisms, which attack our body. Once the immunoglobulin E attaches to the mast cell, histamine chemical will be secreted from this cell. Histamine is the main cause of nasal allergy. It causes the blood vessel in the mucous membranes swelling and leaking of fluid. Swelling causes congestion inside the nasal passages and the leaking of fluid causes runny nose. When the nasal allergy becomes critical, mucous membranes will become inflammatory and itching.

When the immune system in our body finds or realizes anything as foreign to the body, it immediately releases some antibodies like histamines to fight against the foreign substance. This causes inflammation which is called allergy in our body.

Allergy and asthma sufferers have a broad range of improved traditional remedies as well as numerous alternative treatments available to them. Here are some possibilities you may consider.

It's that time of year again. You see it and you feel it. The itchy and watery eyes, the runny nose, the sneezing, a bit of a tight feeling in your chest. It's allergy season - again!

Introduction
Due to increase in the population that is having impaired immunity and also as there is an increasing pool of aged population because of the ever-lowering death rates, the incidence of allergies is on rise.

More than 50 million Americans suffer from allergic diseases. A recent nationwide survey found that more than half (54.6 percent) of all U.S citizens test positive to one or more allergens; among specific allergens, dust mite, rye, ragweed, or cockroach caused sensitization in approximately 25 percent of the population.
