Made from cozy flannel and scented with eucalyptus, vanilla, cinnamon, or plain, rice bags are the best heating/cooling pads. Stick it in the microwave to ease cramps or muscle aches. Stick one in the freezer for bumps and bruises. We used one during my daughters labor and the nurses ordered them for the hospital. These make a perfect, inexpensive gift.
