Rasashastra in Ayurveda
Rasa-Shastra, popularly known as Indian alchemy or Latrochemistry is important subjects of Ayurvedic curriculum. History of Rasa Shastra can be traced to pre-Vedic period, where metals were successfully employed in treatment of various diseases. Ayurveda uses drugs of diverse origins in formulations ranging from herbals to metals. Formulation can be poly-herbal, poly-mineral and herbo-mineral. Rasa Shastra and Dravyaguna are interdisciplinary subjects and they supplement each other. Rasa medicines are widely prescribed by Ayurvedic physicians with amazing results. Use of mercury, copper and gold in treating diseases is documented since times immemorial.
Bhasma of Metals
Ayurvedic theory attributes important therapeutic roles to metals such as mercury and lead. Ayurveda experts estimate that 35% to 40% of the approximately 6000 medicines in the Ayurvedic formulary intentionally contain at least 1 metal. Metal-containing Ayurvedic herbal medicine product are purportedly "detoxified" through multiple heating/cooling cycles and the addition of specific herbs.
The heavy metals in elemental form are toxic but those in compound form i.e. bhasma are safe for humans. Bhasma are prepared from various metals, metal mixtures and alloys. According to Indian alchemy, bhasma prepared, evaluated and therapeutically used are absolute safe to humans.
