Derivation of the botanical name:
Aconitum, ακονιτον, used by Theophrastus(370 — c.285 BCE), & Nicander (2nd century BCE) for a poisonous plant.
lycoctonum, λυκοκτονοϛ (Greek), lycocton, "wolf-slaying".
Pliny the Elder (23-79CE), Natural History, book XXVII:II: "...This was the poison that Marcus Caelius accused Calpurnius Bestia of using to kill his wives in their sleep...Fable has it that aconite sprang out of the foam of the dog Cerberus when Hercules dragged him from the underworld... The plant grows on bare crags which are called aconae, and for that reason some have given it the name of aconite, there being nothing near, not even dust, to give it nourishment".
Aconitum species contain alkaloid acontine, which is one of the most toxic plant compounds known.
They are poiseness, hardy tuberous perennials and in history were used in making arrow poisons. .
