FAQ information about asthma and allergy symptoms. An allergy is your body's response to some stimuli. Our body has an intricate system for getting rid of harmful foreign matter such as bacteria and viruses when they enter the body. The immune system begins to manufacture antibodies to fight them off.

That is why your eyes water, your nose runs, and you begin sneezing wheezing and coughing. To the naked eye, pollen looks like plain powder or dust. It's really the male fertilizing agent for plants.
