Tandochel

This plant grows as a small underground root system. Often the roots penetrate out of the earth and hang.
The stems grow sharp teeth, acting as the plant's seed pods. The roots are no different to the branches and are harvested for their natural lycanthropy-repellent effect. Either hung on home entrances or turned into oils to apply to people. They are found throughout Sey and Enser's untamed land. They are known to be hard to domesticate as they thrive in rough and harsh terrain but die out once they are in a stable environment.
It causes lycanthropes to burn like a rash if they get into contact with it. If smelt it causes their noses to flare up causing a vigorous snout. Long-term exposure shows little consistency, but what's noted is the high level of mutations that have taken effect.
