Dravyaguna Vijnana, the Ayurvedic science of pharmacology, is the study of the properties, actions, and therapeutic applications of medicinal substances — predominantly plants, but also minerals and animal products. It is one of the most essential subjects in the BAMS curriculum, forming the bridge between theoretical knowledge and clinical prescription.
Every medicinal substance (Dravya) in Ayurveda is characterised by its Rasa (taste), Guna (qualities), Virya (potency), Vipaka (post-digestive effect), and Prabhava (special action). Understanding these properties allows practitioners to select appropriate remedies, predict their effects on the doshas, and formulate combinations that enhance efficacy while minimising adverse effects.
Classical texts describe hundreds of medicinal plants, from commonly used herbs like Ashwagandha (Withania somnifera), Tulsi (Ocimum sanctum), and Guduchi (Tinospora cordifolia) to rarer species found in specific ecological regions of India. Modern pharmacognosy and phytochemistry research continue to validate the traditional uses of many of these plants.
At Vishwagurusamwad, sessions on Dravyaguna provide students with practical insights into herb identification, quality assessment, and evidence-based application of traditional plant-based medicines.
