Role of Dravyaguna in personalized medicine and dosha-based therapeutics

Background: Ayurveda, the ancient Indian system of medicine, is built on the principle of individualized care through a unique understanding of human constitution (prakṛti) and the dynamic balance of tridoṣas Vāta, Pitta, and Kapha. Central to its therapeutic approach is Dravyaguna Vijnana, the science of medicinal substances, which offers a comprehensive classification of herbs and compounds based on their taste (rasa), qualities (guṇa), potency (vīrya), post-digestive effect (vipāka), and specific action (prabhāva). Objective: This paper explores the philosophical foundations, pharmacodynamic principles, and clinical relevance of Dravyaguna in the context of personalized medicine and dosha-based therapeutics, aligning Ayurvedic wisdom with modern healthcare paradigms. Methods: A narrative synthesis was undertaken using authentic Ayurvedic texts including Charaka Samhita, Sushruta Samhita, and Bhavaprakasha Nighantu, supplemented by contemporary research on prakṛti-genomics, herbal pharmacology, and systems biology. The dosha-based classification of diseases and therapeutic substances was examined through classical references, shlokas, and modern scientific interpretations. Results: Dravyaguna provides a personalized, adaptive, and context-sensitive therapeutic model. It enables selection and administration of drugs based on individual prakṛti and doshic imbalances, with demonstrated relevance in managing metabolic, inflammatory, neurological, and psychological disorders. The pharmacodynamics guided by Ayurvedic principles offers a multi-dimensional approach not limited to biochemical mechanisms, thus enhancing efficacy and minimizing adverse effects. Conclusion: The resurgence of personalized medicine in contemporary healthcare mirrors the ancient Ayurvedic approach of individualized therapy. Dravyaguna, through its integrative understanding of substances and constitutions, holds significant promise for the future of holistic, preventive, and personalized healthcare. Bridging classical Ayurvedic pharmacology with modern evidence-based methodologies can foster a truly integrative and transformative model of medicine..
