relating to, serving, or used for depuration or purification; having a cleansing function.
From 'depurate' plus '-ory,' an adjective-forming suffix meaning 'relating to' or 'serving to do.' The '-ory' suffix (from Latin '-orius') is common in scientific terminology.
The '-ory' suffix is sneaky and precise—'depuratory' describes something's PURPOSE or FUNCTION rather than just a quality, so a 'depuratory system' is specifically designed to purify!
