Buckthorn
Sorceries, elf magic, and driving away enchantments. Used as a luck generator in legal matters and for winning in court. Place the branches of a Buckthorn near doors or windows to drive away evil and bad vibrations. To make a wish, stand in an open area facing east and concentrate on your wish; turn to your left until you are facing east again, continually sprinkling buckthorn bark powder (or an infusion made with buckthorn bark) as you turn.[1]
