Biomedical Concepts in the Charaka Saṃhitā: A Critical Scientific Review

Abstract

The Charaka Saṃhitā, one of the foundational texts of Āyurveda, represents an intricate synthesis of philosophical, biological, and medical knowledge that predates modern biomedical science by millennia. This paper presents a critical scientific review of the biomedical concepts embedded in the Charaka Saṃhitā, examining their epistemological coherence and relevance in the context of contemporary medical thought. The text’s theoretical framework- rooted in Tridoṣa (three humors), Dhātu (tissues), Mala (wastes), and Agni (metabolic fire) offers an early systemic model of human physiology emphasizing homeostasis, preventive care, and personalized medicine. Through a comparative analysis, parallels are drawn between Tridoṣa balance and modern understandings of neuroendocrine and immune regulation, while the Agni concept is evaluated against metabolic and enzymatic functions. Moreover, Charaka’s emphasis on the psychosomatic unity of body and mind anticipates current approaches in psychoneuroimmunology and holistic health. The review also explores the diagnostic methodologies, pharmacological principles, and ethical standards outlined in the text, which align closely with modern biomedical ethics and evidence-based practice. While the Charaka Saṃhitā employs metaphysical terminology, its empirical orientation through observation, inference, and rational discourse demonstrates a proto-scientific methodology akin to early forms of clinical reasoning. This paper argues that many of the treatise’s core ideas can be reinterpreted through systems biology and integrative medicine frameworks, suggesting that ancient Indian biomedical thought was not merely speculative but systematically empirical. By bridging classical Ayurvedic principles with modern biomedical sciences, this review underscores the potential of cross-disciplinary dialogue in re-evaluating ancient knowledge systems for contemporary healthcare innovation.
