Ayurveda perspective on Malas (excretory products)—Purīṣa (stool), Mūtra (urine), and Sveda (sweat)—posits them as a vital components for maintaining systemic equilibrium. Any derangement in their formation, retention, or elimination gives rise to Mala-pradoṣaja vikāra (disorders due to impaired waste metabolism). Classical texts emphasize that balanced processing and timely elimination of Malas are indispensable for health maintenance. Contemporary medical science validates any alterations in stool, urine, and sweat as critical biomarkers reflecting gastrointestinal, renal, and metabolic function. This review critically analyzes Ayurvedic descriptions of Mala-pradoṣaja vikāra in light of current medical knowledge, highlighting their diagnostic relevance. Understanding this concept is particularly important in today’s world, where lifestyle diseases, stress, and dietary imbalances frequently manifest through altered excretory patterns, making Mala evaluation a valuable tool for preventive and integrative healthcare.
