Reducing swelling and pain from a sprain

I tried this compress the other day when my son sprained his wrist playing football.  He started using it on a Saturday and by Monday he was at least 80% better.

To prepare the compress:
Simmer 2 cups of loose peppermint leaves and 2 tablespoons of coriander seeds in 2 quarts of water for at least 4 hours.  Strain and keep in the refrigerator until you are ready to use it.

Using the compress:
Pour a cup or two at a time into a container and heat up in the microwave or on the stove until it's very warm, but not too hot as to burn the skin.  You can either soak your injury directly in this warmed up mixture, or you can apply it with a wet compress to the area.  Either way, let it soak for about 20 minutes and keep repeating this every few hours until you feel better.
