Executive Summary about what is allergy by: Aster Kitt Brittan
The dictionary makes "allergy" sound simple. Wiki dictionary defines allergy as "A condition of hypersensitivity to a substance (an allergen) considered harmless to most people. Peanuts and shellfish are two known sources that cause violent allergic reactions in some people. In the most simplified terms, the immune systems of people who are allergic overreact when exposed to certain substances that the immune systems of most people have already built up immunity against.
This system is designed to attack and destroy substances that the body comes in contact with that the immune system considers dangerous. The problem of allergies arises when the our bodies launches an attack against perfectly harmless substances, such as grass pollen, cat dander, peanuts, penicillin, or any one of millions of other harmless substances.
The term, "allergy" was first used in 1906 to describe an altered reaction in the body's defense system. Our immune systems have a perfect memory and have total recall. If the immune system over reacts to a substance once, it will always overreact.
