Below is the easiest and fastest home remedy to cure pink eye in humans and animals.
Take a black tea bag (with no additives) and put it in 1/4 cup of very hot water. Let steep until the tea is strong. Apply the tea bag to your eye and hold there for about 2 minutes. Use some of the remaining tea as eye drops (only a few drops). Repeat twice a day and results should quickly follow.
*Note: The remedy works better when you put the tea bag on your eye at the hottest temperature you can stand without burning yourself.
