Hickory,
High John the Conquerer, and
Marigold.
Magickal suggestions for legal matters:
Hickory nuts are lucky for getting people on your side. Carry them in your pocket if you have to go to court and for any proceedings in which people might doubt your sincerity.
-OR-
High John the Conquerer comes in a root and in a powdered incense. If you can get the incense, mix it with galangal; if only the root, just burn bits of it for several nights in a row, concentrating on your problems. Mix the two together in a red cloth and tie it up with a purple or white ribbon, and carry it with you to court.
