Have you ever heard of a mad stone? This home remedy was used for centuries to heal, although it’s not a common practice today.

A mad stone (sometimes called a ‘bezoar stone’) is used to draw poison out of bites and wounds. It works by absorbing the poison bit by bit, curing the bites by detoxifying them completely.

  • Mad stones can be found in the stomach or intestines of cud-chewing animals.
  • Depending on the animal, the stone may be more potent and valuable; for example, the stone of a brown deer is said to be inferior to that of a white deer.
  • Mad stones are not to be bought or sold; such interaction may negate their healing powers.

Naturally, the effectiveness of mad stones has long been in dispute. Can cosmic healing powers really reside in the intestine of a cow? There is only one way to know for sure…

Please Pass the Stone
