ABSTRACT

Rajata Bhasma (RB) is the incinerated form of silver mentioned in Ayurveda in classic texts. This attempt is made to prepare nano particle of rajata bhasma by a novel green method of synthesis without the use of any chemicals. Prepared Nano Rajata Bhasma (NRB) is subjected to traditional evaluation like rupa, varna, nishchandratvam, varitara, rekhapurnatavam, rasa and gandha, in addition to the following tests pH, loss on drying, total ash, specific gravity, total plasmon resonance, zeta potential and FAAS. Marketed rajata bhasma was purchased from local ayurvedic pharmacy and subjected to tests applicable. The results proved that rajata bhasma available from market and prepared nano rajata bhasma were qualitatively the same, in that both contain silver as proved by Atomic Absorption Spectroscopy (AAS).
