Relating to or promoting good digestion; having the quality of being easily digestible or helping the stomach function well.
From Greek 'eu' (well) + 'peptikos' (digestible), the adjectival form of 'pepsis.' This medical adjective entered English in the 18th century alongside other digestive terminology.
Victorians marketed eupeptic biscuits and tonics like we market probiotics today—both eras convinced that digestion was the secret to health, whether that's scientifically true or not.
