All living beings consume food rich in various nutrients, which undergo metabolic processes in the gastrointestinal tract (GIT), where Agni plays a crucial role. In Ayurveda, the concept of Agni—though literally meaning "fire"—refers to the various biological energies responsible for digestion and metabolism in the body. The entire process of digestion, metabolism, and assimilation operates through the coordinated function of three types of Agni: Jatharagni, Bhutagni, and Dhatvagni. Additionally, the process of digestion occurs in three sequential stages known as Avasthapaka, characterized by Madhura Paka (sweet stage) in the stomach, Amla Paka (sour stage) in the duodenum, and Katu Paka (pungent stage) in the intestines. Following these, Bhutagni—the elemental digestive factors—act on the five basic elements (Panchamahabhutas) present in food, digesting them and nourishing their corresponding elemental components within the body. Dhatvagni functions at the tissue level and is primarily responsible for two important activities: the synthesis of new tissues and the generation of energy required for tissue function. After the sequential actions of all these Agni, the food is separated into a nutritive fraction and a waste fraction. The nutritive part is utilized for nourishment, while the waste is eliminated from the body.
