Agrimony finds its use in Hoodoo in works to reverse evil and send back curses.

To remove a curse set against you:

Make a cup of Agrimony tea and add it to warm bath water. Allow yourself to soak for 15 minutes before stepping out. Use a clean, white rag (like a handkerchief) to wipe yourself down from head to toe, set it to the side. Once the cloth is dry, burn it & scatter the ashes at a crossroads.
