Prepare a bath, sun lounge, or floor with towels to lie on. Check to make sure the room is warm because the wrap will cool the body. Put the heater on or an old blanket in reach, if needed.
Mix all the ingredients in a big bowl (If using Epsom salts, combine everything except for the Epsom salts in a bowl. Place 1 cup of the mixture in a separate bowl to use on the face. Stir the Epsom salts into the big bowl of mixture to use on your body.)
Take a warm shower to help open the pores, but don’t shave before the wrap. Spread out the bedsheet and sit in the middle. Using your hands, pat the mixture all over your body, starting with your feet and covering up with the bed sheet as you go. (For extra oomph, wrap yourself in plastic wrap to raise your body temperature and lock in moisture.) Stay there for anywhere from 20 to 60 minutes.
When you’re ready, scrape the body wrap onto the sheet, and dispose or clean it off for another use. I have been known to compost the whole thing, cotton sheet and all. Rinse yourself off under a warm, but not hot, shower. Moisturize with something like coconut oil.
