Natural Treatment for Pink Eye in Kids

I had heard about the coffee remedy from a friend of mine, who's a nurse. Finally tried it. My 7-y-o presented with gooey yellow discharge from eye, crusty eyelashes, and pink "whites of the eye". I treated with warm black coffee dropped into the eye, 3 drops, 4 times a day. Within 24 hours, his eye was completely clear. miraculous.
