Administration of all metals and minerals became possible because of the invention of pharmaceutical technology of converting metals and minerals into Bhasmas. Bhasmas (calx) are peculiar Rasa preparations in which metals and minerals are processed after various Samskaras (processing) like detoxification, (Shodhana) converting into powders (Jarana, causing decay of metals) and incineration (Marana, killing metallic properties) methods. The process of Shodhana removes impurities which are likely to bring about certain toxic effects. Purified substance, whether it is Rasa-Uparasa or Dhatu after maceration with some drugs, when subjected to heat treatment or puta termed as 'Marana'. the process by which Lauha (shada Lauha all dhatus), are transformed to a microfine stage for easy assimilation in the body (at cellular level), without any untoward side effect is considered to be 'Marana'.1 The measure of deciding the degree of paka is called as 'puta-paka'. Among the various intermediatory processes involved in the incineration of Lauha, the 'puta' is of paramount importance owing to the property of bringing Lauha to that state from where it cannot be restored further.2 This process not only removes blemishes but also increases the therapeutic potential of the Lauha. In other words, it is by means of incineration the unwanted metallic properties of Lauha are removed, thus making it suitable for bodily assimilation. This article gives the complete classical review of concept of Puta, it types and its importance in Rasashastra.
