'allopathic' originates from Greek, specifically the word 'allopathia,' where 'allo-' meant 'other' and 'pathos' meant 'suffering.'

'allopathia' transformed into the German word 'allopathisch,' and eventually became the modern English word 'allopathic.'

Initially, it meant 'treatment of disease by opposites,' but over time it evolved into its current meaning of 'conventional medicine.'
