Rasa Shastra deals with the preparation of variety of medicaments and formulations that include Bhasmas, Kharaliya Rasayanas, Kupipakwa Rasayanas, etc. These sections of formulations also depend upon the different types of raw materials that are to be used in it as chief ingredients. Rasa Shastra has a vast and varied history of preparing these medicines and its safer use since thousands of years. Pishti is one such section of formulations that is chiefly used when the raw materials cannot tolerate heat but at the same time are very effective without heat treatment. In Rasa Shastra, mainly the drugs of animal origin or precious gems are subjected to levigation or trituration in a particular media to form a particular Pishti. The word Pishti literally means that which is finely triturated and made into a very fine powder similar to flour. Mukta Pishti, Prawal Pishti being some of the important examples.
