'non-hemorrhagic' originates from the prefix 'non-' meaning 'not' and the word 'hemorrhagic' which comes from Greek 'haimorrhagia' meaning 'a violent bleeding'.

'hemorrhagic' changed from the Greek word 'haimorrhagia' and eventually became the modern English word 'hemorrhagic'.

Initially, 'hemorrhagic' meant 'a violent bleeding', but over time it evolved into its current meaning of 'relating to or involving bleeding'.
