You can find it on the internet and read or even a youtube. Various methods, and you will find your own. Key is a cloth, wool or cotton, and good castor oil. The cloth can be bought on iherb.com or at some health food stores. I really think Premier Research Labs castor oil is much higher quality than available in health food stores. It's still relatively inexpensive, as you need a couple small bottles to get started, but then, ongoing, it's a very small amount you need to add to the cloth. Biggest mistake people make is adding too much oil, then it runs out onto your couch or whatever. Biggest trick is finding a way to keep the oil contained and not getting over everything. I wrap well in plastic wrap (like for food), in one piece, around the body a few times. Still, some will leak, and good sturdy plastic underneath to collect, perhaps with an old towel, is important, as some will leak almost all the time. You need a heater like people use to apply heat to a body, to keep the cloth warm for the hour while over your liver. Some heat the cloth in a dish in the oven first. To me, that just gets you another dish and mess to clean, as the heater will warm it up in 5 or so minutes. The used cloth gets saved in a jar in the refrigerator, so taking it out a couple hours ahead of time allows it to warm up first a little bit. These are just my thoughts, they'll probably make more sense after watching/reading about it from one or two other sources, but, like I said, everyone will get their own methods.
