Rasayana Shastra (Samskrit: रसायनशास्त्रम्) referred to the subject of Chemistry based on the chemical activities involved in biological and inorganic processes. It was also called Rasatantra, Rasa Kriya or Rasa Vidya roughly translating to 'Science of Liquids'. "Rasa" in ayurvedic terminology refers to mercury and [[Rasashastra (रसशास्त्रम्)|Rasashastra]] exclusively deals with the treatment using mercury and its compounds. It is well known that science and technology in ancient and medieval India covered all the major branches of human knowledge and activities, including mathematics, astronomy, physics, chemistry, medical science and surgery etc.
