What are eosinophils?

ANSWER

Eosinophils are white blood cells. They’re part of your body’s immune system, and normally, they help you fight disease. One of their jobs is to help cause swelling. That may sound odd, but swelling is one of your body’s key tools in fighting germs. But too much swelling can cause problems.
