Madstone

Gnosis: 5 This is a stone taken from an unpolluted place (like a clear river, a hidden cave, or an inaccessible clearing). When it is activated and placed upon a poisoned wound (such as from a snakebite or from a toxic Wyrm-creature), it will draw out the poison as if the Gift: Resist Toxin had been used. It wilt also cure rabies either in the victim of a bite from an infected animal or in the animal itself.
