The name “hag stone” originates in part from ancient beliefs that most maladies, which were curable by using this stone, were caused originally by spectral hags.
Other areas call them adder stones because they are believed to protect the wearer from the effects of snake bite. Germanic legend says that adder stones are formed when serpents gather together and use their venom to create the holes in the centre of the stones.
Hag stones are said to have many uses. They have been used by witches worldwide for centuries in both rituals and spell work. They also have been used, ironically, as a toll to counteract a witch’s magic.
Legend has it that they can be used to ward off the dead, curses, sickness and nightmares.
