STUDY OF STANDARD OPERATING PROCEDURE OF NAAG SHODHANA IN RELATION TO ITS PHYSICO-CHEMICAL PROPERTIES

Abstract

Standard operating procedures (SOPs) should to be designed, implemented and set for all Ayurvedic drugs one by one for globalization Ayurveda. In this study, an attempt has been made to introduce SOP for preparation of Naag Shodhana [NS] & its analytical study. Study was conducted in the Department of Rasa Shastra under the postgraduate research programme is being presented. The pharmaceutical processing of NS was performed by four different methods

i.e. Samanya Shodhana, Vishesh Shodhana, Samanya Shodhana preceded by Vishesh Shodhana & control. Samples of unpurified & purified Naag (Pb) were analyzed physico-chemically and comparison was drawn to lay down pharmacopoeial standards. All the samples of Shodhit Naag obtained using textual references showed considerable increase in the percentage of Lead and decrease in the impurities. The Shodhana dravyas were also analyzed physico- chemically before and after Shodhana. But no significant differences were observed in their physico-chemical properties. The Naag obtained after dhalana in distilled water neither showed increase in the percentage of Lead nor decrease in the percentage of impurities. However, no significant difference was found in the Shodhit Naag obtained from various types of Shodhanas viz. Samanya Shodhana, Vishesh Shodhana and Vishesh Shodhana preceded by Samanya samples in relation to their physico-chemical properties. It can be concluded from study that it is imperative to perform Shodhana process as described in the Ayurved texts, as Shodhana Dravyas definitely play an important role in decreasing the impurities.
