Wolfsbane :
Wolfsbane, also commonly known as Monkshood, is more properly called Aconitum, a perennial flower that prefers cool, moist soil. All parts of Aconitum are poisonous to humans, especially the roots.
How it typically affects a werewolf:
- It gives off an irritable smell.
- If a werewolf comes in contact with Wolfsbane, he can develop a rash.
- If he swallows it, he will be quite sick for the next couple of days.
- Sometimes, however, a potion derived primarily from Wolfsbane can present a cure for lycanthropy.
