Moly (herb)
==Moly== (Greek: μῶλυ) is a magic herb with a black root and white blossoms in Greek mythology. In Homer's Odyssey, Hermes gave this herb to Odysseus to protect him from Circe's incantation. It can be plucked only by celestial hands.
In the Harry Potter books, moly is mentioned as a potion ingredient.
The common English interjection, "Holy moly!" comes from the name of this herb.
