'non-therapeutically' originates from the prefix 'non-' meaning 'not' and the word 'therapeutic' which comes from Greek 'therapeutikos', meaning 'pertaining to treating or curing disease'.

'therapeutikos' transformed into the Latin 'therapeuticus', and eventually became the modern English word 'therapeutic'.

Initially, it meant 'pertaining to treatment', but over time it evolved to include the prefix 'non-' to indicate the absence of therapeutic intent.
