ABSTRACT

Parada is most important among rasa subastance. But parad is not therapeutically used in its natural form. At present, the new drug development process looks to be at a stagnant state. There is neithera good work on the chemistry point of Rasau-shadhis nor are trials being made. To developa new Rasaushadhi compound, work on the Rasaushadies is limited to some classical for-mulations that too is not perfectly standar-dized. Present chemical labs identify purely prepared Kajjali, Ras Parpati, Ras Sindoor and Hingula, same as HgS. Rasa formulations are prepared from shuddha parada, samskarit parada, sanskarita parada or hingulottha parada. To add the therapeutic qualities to parada, it is processed with different substance. Based on procedure, processing of parada is of four types. Kharleeya rasayana, parpati formulations, kupipakwa and bahirdhoom. The colour of finished product depends on the ingredients used formulation, and bhasma formulation. Among these four procedures, the kupipakwa procedure is the basic one. Kupipakwa rasayan is composed of four words kupi, pakwa, rasa and ayana. A rasayana product from parada, gandhaka etc is prepared in a glass bottle by applying mild, moderate and intense heat. Based on preparation method it is classified into antar dhooma.
