Question

how to prepare a heating compound for pain made out of white rice

Answer 1

You must mean a "rice sock."

Fill a clean sock loosely with rice. That is, full, but loose enough to drape around a wrist or ankle. Sew it shut. Place it in the microwave to warm it, but don't get it so hot that it will burn your skin. Place it over the affected area. When it cools down, you can warm it again and repeat. Wonderful therapy!

Answer 2

Put the rice in a bag and heat in the microwave for one minute at a time so it's not to hot for the skin
