Accounts differ widely on how to make and use a ‘black stone’.
Dr. Linnea Smith reports that, in Peru, a black stone is a small charred cow bone, “applied to the site of a poisonous snakebite and tied firmly in place.

It is left there for several days, during which time it supposedly draws the venom from the wound.

Once the poison is all removed, the ‘stone’ loosens of its own accord and falls off. … despite the fact that the state nursing course book admits that no evidence has ever been produced to document the effectiveness of the black stone, each student is required to make … one … as a part of the first aid module.”

Persian/Iranian writer Kazwini describes the snake-stone as being the size of a small nut.[citation needed] An injury inflicted by a venomous creature is to be immersed in warm water or sour milk. The snake-stone is then dropped into the liquid to supposedly draw out the poison.

Although called a ‘stone’, in the Congo a Black Stone is often made from animal bones. When taken from snakes, it is usually from the head, but also said to be extracted from the tail.
