'autoplasmotherapy' originates from modern medical English, formed from Greek elements: 'autos' meaning 'self', 'plasma' meaning 'that which is formed' (or 'something molded'), and 'therapeia' meaning 'healing' or 'treatment'.

'autoplasmotherapy' was coined in recent medical usage by combining the Greek roots 'autos' + 'plasma' + 'therapeia'; it does not descend from a single older English word but is a compound created in modern clinical terminology.

Initially and currently it refers to a therapy using a patient's own plasma; the core meaning has remained consistent, though usage has broadened as techniques (e.g., platelet concentration) have developed.
