The act of bleeding or the flow of blood; an archaic medical or poetic term for bloodshed.
From Latin 'cruentatio', derived from 'cruentatus' (bloodied), with the '-tion' suffix that forms abstract nouns of action or state from Latin-derived words.
Medieval and Renaissance doctors actually used this term—'cruentation' was part of the technical vocabulary when blood was thought to be one of the four humors controlling health.
