An Allergy is your immune system's abnormal reaction to contact with a specific substance. It's your body's reaction and the chemicals it releases, that cause the sneezing, rash, or irritation etc. It is not the foreign substance or organism itself that causes this but your body's own immune system overreacting. Usually this is an overreaction to histamine, a chemical that the body releases to fight microbial invaders.
