'medically-supervised' originates from the combination of 'medical' and 'supervised', where 'medical' is derived from Latin 'medicus' meaning 'physician', and 'supervised' from Latin 'supervidere', where 'super-' meant 'over' and 'videre' meant 'to see'.

'medically-supervised' changed from the combination of 'medical' and 'supervised' in modern English to describe processes or actions overseen by medical professionals.

Initially, it meant 'overseen by a physician', but over time it evolved into its current meaning of 'under the supervision of any medical professional'.
