English speakers took panacea from Latin, but as is the case with many Latin borrowings, the word ultimately traces its roots to Greek: panakēs, meaning "all-healing,” comes from pan-, meaning "all," and akos, meaning “remedy.” The Latin designation Panacea or Panaces was in past centuries awarded to various plants, among them the herb today known as Prunella vulgaris, whose common name is self-heal. In current use, panacea is most often used to decry a remedy that falls far short of what some claim it can do.
