Viral infections, bacterial infections, or allergies can cause conjunctivitis, which is an inflammation of the mucus layer that covers the eye. Because it can cause inflammation and swelling, cold compresses can be very helpful. To treat the infection, honey water can be used to cleanse the eye. However, having your child drink echinacea tea to treat the infection might be an easier approach since most kids don’t like eye drops. Conjunctivitis can be extremely unpleasant, and using one or two of these methods to ease the symptoms could make it a little more bearable.
