Abstract

Jatharagni is the principal digestive and metabolic fire described in Ayurveda, governing transformation of ingested food into nutritive essence (ahara rasa). Classical literature identifies agni as the determinant of health, strength, complexion, immunity, and longevity (1). Contemporary biomedical science attributes systemic metabolism to coordinated enzymatic, mitochondrial, and endocrine mechanisms. Despite conceptual parallels, systematic comparative analysis remains limited.
