THE INTERRELATIONSHIP OF VATA DOSHA, ASTHI DHATU, AND ASTHIVAHA SROTAS IN THE PATHOGENESIS OF ASTHIPRADOSHAJA VIKARA

Abstract

Background: Ayurveda describes skeletal health through the interdependent concepts of Vata Dosha, Asthi Dhatu and Asthivaha Srotas. Their relationship is clinically important because Vata is located in Asthi, while excessive Vata and inadequate tissue nutrition are repeatedly associated with depletion, pain and structural deterioration. Objective: To critically analyse the Vata-Asthi relationship, the functional significance of Asthivaha Srotas and their combined role in the pathogenesis of Asthipradoshaja Vikara. Methods: A critical narrative review was undertaken using the Brihattrayi, principal commentarial interpretations and selected contemporary literature on bone remodelling and musculoskeletal ageing. Classical concepts were compared thematically under Dosha, Dhatu, Agni, Srotas and Samprapti. Results: The reviewed framework suggests that Asthi pathology cannot be reduced to a local defect of bone. Vata-provoking exposures, Agni and Asthi-dhatvagni disturbance, defective Dhatu-poshana and Asthivaha-srotodushti interact to produce either depletion-dominant or abnormal-growth manifestations. Asthi Kshaya may further favour Vata aggravation, generating a self-perpetuating cycle. Classical descriptions of teeth, nails, hair, pain, fragility and abnormal bony growth broaden the clinical field beyond a single modern diagnosis. Discussion: Contemporary bone-remodelling concepts provide useful analogies, but direct equivalence between Vata and neural regulation, or between Asthi Kshaya and osteoporosis, is methodologically unsound. Conclusion: Vata, Asthi and Asthivaha Srotas form a coherent systems-level model linking causation, tissue nutrition, transport and manifestation. This model supports early assessment, subtype-sensitive management and research based on operational Ayurvedic phenotypes.
