A perspective on excreted metabolites (Malas) as a non-invasive tool for assessing Dosha-Dhatu balance

Abstract Ayurveda considers Malas to be fundamental physiological components crucial for maintaining internal bodily homeostasis. Malas are categorized as either Prakrita , resulting from normal physiological processes, or Vikrita , emerging from pathogenesis. Purisha and Mutra are formed as Anna-Mala , while Sweda is categorized as Anna-Mala and Medo Mala. During the metabolism of Dhatu , various Dhatu Malas are produced. Furthermore, the component, that is, harmful to the body is referred to as Mala . Vitiated Doshas and Dhatus are also termed as Malas . Consequently, the analysis of these Malas provides a critical, noninvasive window into the internal state of the Doshas and Dhatus , offering valuable insights for both diagnosis and treatment. The concept of Mala closely parallels the modern physiological understanding of metabolic waste and excreta. Metabolic wastes are biochemical byproducts formed during intracellular processes, which are then processed and eliminated from the body as excreta to maintain homeostasis. Modern laboratory analysis of metabolic waste and excreta offers a wealth of objective data regarding the body’s internal components, providing valuable insights into a person’s health status. The interpretive correlation of contemporary laboratory results with the foundational Ayurvedic concepts of Doshas , Dhatus , and Malas allows for a more comprehensive assessment of a patient’s internal homeostasis. This paper explores the potential of using modern laboratory parameters to evaluate metabolites excreted through Malas as a noninvasive tool to gain objective insights into Ayurvedic constructs, including Dosha - Dhatu balance and early pathological changes. By integrating classical knowledge with contemporary laboratory analyses, this approach aims to provide a framework for early diagnosis and monitoring of disease, bridging traditional and modern perspectives on metabolic health.
