Aconite

"As for monkshood and wolfsbane, they are the same plant, which also goes by the name of aconite. Well? Why aren't you all copying that down?"

Aconite (also known as monkshood or wolfsbane) is a plant with magical uses. Once widespread, this plant is now only found in wild places. Its flowers are useful in potion-making, but its leaves are very toxic. Aconite is most commonly known as an ingredient of Wolfsbane Potion. The root of aconite can be used as a potion ingredient.
