Azure Bitterspice Tea
Description: Azure Bitterspice is a fern-like plant colored a vivid blue-white. It grows only in areas contaminated with eldritch energies from ice-aspected magical disasters; the kind associated with entire neighborhoods or towns vanishing in the snow, never to return. Azure Bitterspice should never be touched with bare hands: the leaves need a half hour of immersion in boiling water before they can be safely handled.
Effects: Preservation. Someone who drinks a cup of Azure Bitterspice Tea (it tastes awful, by the way) will swiftly slip into a frozen state where all life functions almost cease to function, very much including bleeding. This is effectively suspended animation, and lasts for as long as the subject is in an environment that is below 100 degrees Fahrenheit. Some people have been frozen for more than a century without ill effects.
