Preparation and standardization of kasis bhasma by two different methods and its analytical study

Abstract

Different ayurvedic texts have mentioned different methods of shodhan (Purification) and maran (incineration) of ayurvedic mineral preparations of kasis. Though different methods of shodhan and maran are described in various texts complete physio chemical standardization is necessary to prepare the pure form and for quality assurance as well as It is necessary to understand the chemical changes that take place after various ayurvedic processes. Aims and Objectives: 1. Procurement of grahya kasis from local market and its chemical analysis 2. Purification of kasis in dolayantra and its chemical analysis 3. Preparation of kasis bhasma by two methods given by ras tarangini and its chemical analysis. Setting and Design: observational analytical study. Place of study: Department of Rasa Shastra and BK, GS Ayurvedic medical college. Materials and methods: Ashudhha kasis is purified and subjected to incineration by two types, Snuhipatra swaras bhavana, and kanji and Nimbu swaras bhavana as given in rasa tarangini. Chemical composition of the raw form, pure form as well as two types of bhasmas is analyzed in laboratory. Results: 1. Analysis of kasis at each stage of its formation to kasis bhasma shows the changes in physical and chemical properties due to its transformation as it is heated thermal decomposition starts 2. The chemical analysis of kasis bhasma shows highest percentage of ferric iron in comparison with raw and shodhit form. 3. Chemical analysis of kasis bhasma obtained by incineration process, by Snuhipatra swaras bhavana, and kanji and Nimbu swaras bhavana does not show any notable difference in chemical composition. Both methods can be used to prepare kasis bhasma as per availability of bhavana dravya.
