"discharge from the uterus after childbirth," 1680s, Modern Latin, from Greek lokhia "childbirth," neuter plural of lokhios "pertaining to childbirth," from lokhos "a lying in, childbirth," also, "an ambush," from PIE root *legh- "to lie down, lay." Related: Lochial. Greek Lokhia also was an epithet or surname of Artemis in her aspect as protectress of women in childbirth; in this case it is the fem. of the adjective lokhios.
