The growing global use of Ayurveda has increased demand for medicinal plants used in preventive, therapeutic, and integrative healthcare. This expansion has strengthened Ayurvedic pharmacology but has also raised ecological, quality-control, and environmental health concerns, particularly where botanicals are obtained from wild or weakly monitored supply systems. This review examines sustainable medicinal plant sourcing as a central requirement for biodiversity conservation, raw material authenticity, and public health protection in Ayurvedic drug discovery. It focuses on therapeutic expansion, disease-specific pharmacological applications, phytochemical evidence, conservation pressure, agro-ecological cultivation, authentication, contamination control, and safety assessment. The review concludes that environmental sustainability should be treated as a determinant of medicinal plant quality because overharvesting, habitat degradation, adulteration, species substitution, and contamination can compromise both ecological stability and therapeutic reliability. Sustainable cultivation, botanical repositories, traceability systems, toxicity screening, efficacy-oriented quality grading, and community-based resource governance are recommended to support safe, authentic, and therapeutically consistent Ayurvedic herbal medicines.
