Toad stone

from Wikipedia, the free encyclopedia

Borax - toad stone. Illustration from the Hortus sanitatis Mainz 1491

Toad stone ( borax ) was called a calculus that was supposed to grow in the toad's head. Swallowed and excreted with the bowel movement, the toad stone should detoxify the body. Set as a ring or worn around the neck as an amulet, it should protect against poisoning.
