Monkshood

Monkshood is a genus of flowering plant belonging to the buttercup family. A cousin to the more popularly known wolfsbane, this perennial flower only grows in the Spring. It is believed that concentrated doses of monkshood could be used to ward off, or even harm those affected by lycanthropy, the disorder in which a person believes they are a werewolf. In some cases, Monkshood might even be able to be distilled in order to create a cure for lycanthropy.
