Dravyaguna is one of the fundamental branches of Ayurveda that focuses on the detailed study of medicinal plants, their pharmacological properties, actions, and therapeutic applications. The term “Dravyaguna” is derived from two Sanskrit words: Dravya (substance or medicinal drug) and Guna (properties or qualities). This subject plays a crucial role in Ayurvedic medicine by providing a comprehensive understanding of how various natural substances interact with the human body.

          Dravyaguna encompasses not only herbal medicines but also minerals and animal-derived substances used in Ayurvedic formulations. The study involves the identification, classification, and proper usage of medicinal plants based on Ayurvedic principles. It aims to bridge the gap between traditional wisdom and modern scientific research, making Ayurveda more effective and evidence-based.

          This subject is essential for every Ayurvedic practitioner as it enables them to prescribe appropriate herbal medications based on individual patient needs, disease conditions, and the principles of Ayurvedic pharmacology.
