Agni–Agrya-Upakrama: Supremacy of Agni in Physiology–Pathology–Panacea

A bstract Āyurveda provides detailed descriptions of Dravyas (medicinal substances) to maintain Dhātusāmya (normalcy of bodily tissues), with Agrya Saṅgraha (collection of foremost substances and activities) being a notable example. Very few studies have explored the clinical rationale underlying Agrya Saṅgraha . This study is one such attempt directed to critically analyze the role of Agni (external heat) in pacifying Āma (undigested matter), Stambha (stiffness or rigidity), Śīta (coldness), Śūla (sharp pain), and Udvepana (tremors or tingling sensations); further examine its therapeutic application through Upakrama (treatment methods); and finally evaluate the rationality of Agrya Saṅgraha . Concepts were compiled from the Bṛhatrayī , Gaṅgādhara , and Cakrapāṇī Vyākhyā on Caraka Saṃhitā , and contemporary research articles. Agni and Upakrama principles were collated, pathological and treatment aspects of the above conditions were analyzed, and their correlation with Upakrama was examined. Findings suggest that Agni , as an external source of heat, is central to Svedana Upakrama (sudation therapy), while Ātapa Sevana (sun exposure) and Vyāyāma (exercise) represent Niragni Sveda (sudation through an indirect source of heat), useful in Āmadoṣa (conditions afflicted with Āma ). Svedana Upakrama benefits both Vāta and Kapha -predominant disorders, alleviating Āma, Stambha , Śīta , Shula , and Udvepana . Agrya Saṅgraha further exemplifies a structured, action-oriented approach combining diet, regimen, and drugs, highlighting that planned interventions surpass mere knowledge of individual Dravyas . Thus, the study affirms the textual and physiological coherence of Agni -based therapies, particularly Svedana , in treating Āma -related and Vāta–Kapha -dominant disorders.
