For centuries, Toadstone was thought to have magical properties and was used for rings and amulets from Medieval times throughout the 18th century. ⁠

In the presence of poison, a toadstone was believed to sweat, change colour and even heat up. It was believed that a toadstone placed on a bite from snakes, insects, spiders and shrews could extract the poison from a wound. ⁠ ⁠A Toadstone, was thought to have been formed in the head of a toad.
⁠
In fact, now known as bufonite, toadstones are actually fossilized teeth of Lepidotes, an extinct fish from the Jurassic and Cretaceous periods.
