  • Allergy occurs when the personís body over reacts to something that is normally harmless like eggs, nuts, dust or pollen
  • When the personís body over reacts their immune system produces a special kind of antibody called IgE and releases chemicals called histamines into their body to fight off the thing theyíre allergic.
  • The histamines cause the symptoms like itching, coughing and sneezing.

  Jokes
A peanut sat on a railroad track,
His heart was all a flutter,
A train came racing down the track,
Toot, toot - peanut butter!
