Sajjanar * 11 -0001 109 112 For thousands of years, the Ayurvedic pharmacy process of Bhavana (wet grinding or levigation) has been utilized to enhance the potency and safety of therapeutics. Traditionally categorized as a Sanskara (transformation), this process imparts Suksma (minute or subtle) qualities to the medicine. While historically approached through an experience-based paradigm, this review examines the traditional mechanisms of Bhavana through the modern lenses of materials science and pharmacology, proposing it as an ancient, highly intelligent form of eco-friendly green nanotechnology. A synthesis of classical Ayurvedic texts and contemporary modern research demonstrates that continuous mechanical friction during Mardana (grinding) reduces particle size via physical shear forces, acting as a top-down synthesis method. Concurrently, plant exudates within the Drava (liquid medium) form a protective phytochemical coating around these newly cleaved particles, representing a bottom-up synthesis method. This dual mechanism prevents particle agglomeration, alters surface electrical charges, and yields stable nanoparticles with enhanced lipophilicity and cellular absorption. Therefore, Bhavana transcends simple mechanical grinding to function as an early form of bio-nanotechnology. This perspective not only validates the scientific foundation of classical Ayurvedic pharmaceutics but also offers a sustainable, non-toxic model for contemporary drug manufacturing.
