Magical Uses: Worn, St. John’s Wort wards off fevers and colds, makes soldiers invincible, and attracts love. If it is gathered on Midsummer or on a Friday and worn it will keep mental illness at bay and will also cure melancholy. When placed in a jar and hung by a window, St. John’s Wort protects against thunderbolts, fire and evil spirits. Both flowers and leaves are used for this purpose. It is also dried over the Midsummer fires and hung near the window to keep ghosts, necromancers and other evildoers from the house, and is burned to banish spirits and demons.

Any part of the herb placed beneath the pillow allows unmarried women to dream of their future husbands. Use in rituals or carry to detect other magicians; at one time it was held to the mouth of accused Witches to attempt to force them to confess.
