Magical Uses: Placed beneath the pillow heliotrope induces prophetic dreams. This is especially useful when you have been robbed—the thief will appear in a dream.
Heliotrope is used in exorcism incenses and mixtures, as well as healing sachets. When placed in the pocket or purse it attracts wealth and money. Also ring green candles and burn down to the socket.
To become invisible, fill a small horn with heliotrope. Wear or carry and your actions and movements shall not attract attention.
