Devils Shoestring is a very traditional North American Hoodoo root; used it protection and warding spells, mojo bags, and spell bottles.
Said to trip or tie up the Devil's feet so he can't move against you; to stop negative energy trom encroaching on your property or around you.
Bury by your front door or add to a mojo bag to carry or hang near your entrance; add to Van Van oil to increase it's potency.
