At first glance, this humble and pretty purple flower seems to be innocent. However, aconite is also known as 'plant arsenic,' 'queen of poisons,' or ‘wolf’s bane,’ and all these common names hint something. Hecateis is another wat to name this plant. If you are familiar with ancient Greek mythology, you know that it references Hecate, goddess of witchcraft.
That is why aconite was popular among witches. One of them was legendary Medea, well-known sorceress who tried to poison Theseus with this. Also, Athena turned Arachne into a spider by using aconite. Transformational qualities of this plant were mentioned not only in Greek mythology, but in Germanic legends as well. For example, the berserks consumed aconite to transform into werewolves.
