'allopath' originates from Greek, specifically the word 'allos,' meaning 'other,' and 'pathos,' meaning 'suffering.'

'allopath' was derived from the Greek word 'allopathēs,' which was used in the 19th century to describe practitioners of conventional medicine.

Initially, it referred to practitioners who used treatments that caused effects different from the disease, and this meaning has largely remained the same in modern usage.
