WOLFSBANE: a toxic also known as “Aconitum”, flowering plant that can be used to repel Werewolves if great care is taken in its usage; an excessive amount actually increases the chances of savage transformations.
suis0u: WIP I | WIP II | WIP III It’s finished, finally! And because some of you already asked, you can find it on society6 as well :)(Actually I have planned a background, but no time and motivation to be honest…)
Monkshood: Aconitum nagarum, dark purple form. I can't pin down a variety or a source for seeds, sadly. You will have to do a bit of sleuthing if you want one. Excellent for a poison garden; not so good if you have kids around.
