Buy a cows tongue at the grocery store, slice it open length wise (top and bottom) between halves place a piece of paper that you have written the person who is lying name on, be detailed as you can. roll the tongue up (tip to back) and drive 7 nails, 7 pins and 7 needles thru the tongue each time saying something like (name) cannot lie; Wrap the tongue up in red cloth and leave it in the woods with 7 pennies.
This one sounds a little gross to me, but here it is anyhow.
