A fabulous herb which can resist sorceries. The root is black while the flower is as white as milk. Mortal man can not uproot it, but the gods can do whatever they like. Hermes gave it to Odysseus when the latter was stranded on Aeaea and half his men were turned into swine by Circe. It acted as an antidote to Circe's charms.
