Minthe

In ancient Greek religion and Greek mythology, Minthe or Mintha (Ancient Greek: Μίνθη, romanized: Mínthē, lit. 'mint') is an underworld naiad associated with the river Cocytus. She was beloved by and mistress to Hades, the king of the underworld, but she was transformed into a mint plant by either his wife Persephone or her mother Demeter. The plant was also called by some as hedyosmos (Ancient Greek: ἡδύοσμος), which means "sweet-smelling".
