Rasa Shāstra Is quite simply medical alchemy, its texts centring on a bewildering array of minerals, metals, gemstones and poisonous plants. These materials were developed as highly potent medicants after a series of detailed and labour intensive purification and preparation methods. Rasa medicines were not only enlisted for the purposes of healing but also life extension. In Sanskrit the word ‘Rasa’ maybe used to denote the metal mercury (or quicksilver). In conjunction with the word Shāstra (knowledge or science) the term Rasa Shāstra can be translated as the science of mercury.

Āyurveda uses the term rasayana to describe substances or practices that extend life and impart youthfulness.  Many Ayurvedic formulations aim to regenerate the body and build strength, it’s in these rasayana formulations that rasa medicines are seen prominently. Mercury was thought to have miraculous properties for extending life and for the bestowing of super human powers.  Ingestion of mercury (in a sulphide form) was thought to transmute the body’s tissues, making them impervious to the ravages of time.
