'haemostatic' originates from Greek and New Latin, specifically the elements 'haima' and 'stasis', where 'haima' meant 'blood' and 'stasis' meant 'standing still' or 'stopping'.

'haemostatic' developed via New Latin 'haemostaticus' from Greek roots 'haima' + 'stasis', and entered English medical usage as terms related to 'haemostasis' (control of bleeding).

Initially it referred to the process or means of causing 'haemostasis' (stopping blood flow); over time it became used both as an adjective describing that property and as a noun for agents/devices that stop bleeding.
