Standard manufacturing procedure of Rajata Bhasma.
Rasa Shastra is a branch of Ayurveda which deals with the processing of minerals and metals having therapeutic importance. Rajata comes under the group of metals having high therapeutic value. Minerals and metals are mostly used in the form of Bhasma. During the medieval period Rasacharyas extensively worked and developed a number of processing methods for a single drug. They all are standard manufacturing procedures (SMP) which ensure the quality, safety, efficacy and reproducibility of the product. Earlier Ayurvedic physicians were producing medicines by themselves according to their need. Now a day, due to commercialization of Ayurvedic medicines and ignorance of classical methods, quality of drugs has deteriorated. Presently, the demand of Ayurvedic drugs in the global market is increasing day by day. Hence it is the need of time to develop SMP for Ayurvedic products for global acceptability. This paper aims at providing SMP for the manufacture of Rajata Bhasma and also attempts to study the effect of Shodhana process on Rajata. Rajata was obtained from the local market of Varanasi. Rajata Bhasma was prepared and it was observed that during the preparation of Rajata Bhasma, use of Muffle Furnace instead of conventional Puta is more advantageous due to better temperature control. Use of mercury and sulphur together acts as best medium in the preparation of Rajata Bhasma.
