We now use "Wheat Bags" ... cloth bags, usually cylindrical, filled with wheat. Heat in a microwave and use where one would use a hot-water bottle, but without the danger of a leak.

I've seen people fill socks with uncooked rice, tie off the end. Then you can stick it in the microwave for a couple of minutes.
