Ayurveda and Preventive Public Health in India: A Policy Perspective for Primary Health Care.

Community medicine emphasizes health promotion and disease prevention at the population level. In India, the growing burden of lifestyle-related non-communicable diseases (NCDs) highlights the need for effective preventive and promotive strategies. Traditional systems that prioritize lifestyle regulation and early risk modification are therefore of increasing relevance. To discuss the preventive role of Ayurveda in the context of rising non-communicable diseases and to highlight its potential relevance for primary health care and community medicine. This viewpoint draws upon selected evidence from contemporary public-health literature, relevant policy documents, and classical Ayurvedic texts, including the Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, to discuss the preventive orientation of Ayurveda in relation to community medicine. Rather than presenting a systematic review, this article offers a conceptual perspective on how Ayurvedic principles of lifestyle regulation, dietary practices, and health promotion may complement contemporary public-health strategies for the prevention of non-communicable diseases and the strengthening of primary health care. Available literature and classical Ayurvedic principles suggest that lifestyle regulation (Dinacharya, Ritucharya), dietary discipline (Ahara, Pathya-Apathya), metabolic regulation (Agni), and ethical conduct (Sadvritta, Achar Rasayana) are conceptually aligned with contemporary public-health approaches aimed at health promotion and disease prevention. Integration of Ayurvedic lifestyle counselling, dietary guidance, and community-based practices within primary health care can support risk-factor modification for non-communicable diseases (NCDs) in a low-cost, culturally acceptable manner. Ayurveda may represent a conceptual preventive framework that may complement contemporary public-health strategies. However, further high-quality evidence is required before widespread implementation can be recommended.
