This is a great way to support your detox - by putting Castor Oil on a warm pack and applying it to your skin, over your liver or abdomen, or any area that requires support. For a cheap way to do this, use old cotton or flannel fabric, and cover with plastic. This kit is not expensive and does the trick. There are more expensive packs out there, but this one works for me for now. Always use a high quality castor oil to ensure that your detox is safe
