The preparation which are prepared thin flakes form (sheet) are termed as Parpati and the entire operation comes under parpati kalpana. In Ayurvedic Rasashatra three paka (stages) have been mentioned for Rasa parpati preparations. These are Mridu, Madhya and Khara pakas. Parpati obtained by Mridu, Madhya pakas are considered to be of therapeutic value and are advocated for clinical usage, but those obtained by Kharapaka is not recommended. The reason for this is not known and there is no report in the literature explaining the rationale for the preference of parpati obtained by Mridu and Madhaya paka only. In the present study, an attempt has been made to standardize the procedure, stages of parpati with reference to Rasaparpati to know the difference between trividha pakas. During the study, it was observed that the time between the stages (pakas) are very short, the sulphur is in more free form in the Kajjali as compared to parpati.
