'therapeutically-managed' originates from the Greek word 'therapeia,' meaning 'healing,' and the English word 'manage,' which comes from the Italian 'maneggiare,' meaning 'to handle.'

'therapeia' transformed into the English word 'therapeutic,' and 'maneggiare' became 'manage' in English, eventually forming the compound adjective 'therapeutically-managed.'

Initially, 'therapeutic' meant 'healing,' and 'manage' meant 'to handle or control.' Together, they evolved to mean 'managed in a healing manner.'
