- meconium (n.)

- "fecal discharge from a newborn infant," 1706, from Latin meconium "excrement of a newborn child," literally "poppy juice," from Greek mekonion "poppy-juice, opium," diminutive of mekon "poppy" (perhaps cognate with Old Church Slavonic maku, German Mohn "poppy"). So called by classical physicians for its resemblance. Related: Meconial.
