A REVIEW ON THE YANTRAS WITH SPECIAL REFERENCE TO COMMONLY USED YANTRAS IN RASOUSHADHI NIRMANA

Abstract

Rasasastra is an integral part of Ayurveda, dealing with various metals, minerals, drugs of animal origin, their properties, varieties, processing, therapeutic uses etc. For the various processing of rasa uparasadi dhatus and for the preparation of medicines, specific apparatuses called ‘Yantras’are needed. A literary search through the treatises of Rasasastra revealed a number of yantras, of which many are uncommon in use today. In light of this fact, it is inevitable to have an understanding of the yantras that are put to use in today’s times. The present article throws light on the yantras commonly employed in the pharmaceutical preparation of rasoushadhis and also a clear representation of the subject concerned.
