RASA SHASTRA-A NANO TECHNOLOGY OF AYURVEDA MEDICINE
Nano technology is a very fast emerging branch of science where the particles of a matter are reduced to nano size. The size of the nano particles is between 1 and 100 nanometers and it is defined as a small object that behaves as a whole unit with respect to its transport and properties. It is a bridge between its gross form and molecule. Materials reduced to nanoscale show different properties compared to what they exhibit on a macro-scale. For instance, opaque substances become transparent in nano state e.g. copper; stable matter turn to combustible e.g. aluminum and insoluble substances turns to soluble e.g. gold. A material such as gold, which is chemically inert in its gross-form becomes a potent chemical catalyst at nano-scale. Gold nano-particles have the potential to have many therapeutic actions into a single platform, by targeting specific tumor cells, tissues and organs.
Methods for creating nanoparticles include attrition, pyrolysis and hydrothermal synthesis. In Rasa Shastra somewhat similar methods are used to prepare Bhasma, Kupi-Pakva Rasayana, Kshara Sutra etc. The end products obtained by such Ayurveda methods show different properties in respect to its macro-scale form. For example Bhasma of heavy metals floats on water, instead of settling down it remains as suspension in water and color is also changed. Inert material used in making Kshara becomes very corrosive in its Kshara form. Hence most of mineral/metal drugs of Ayurveda converted into its harmless nano form by processing them through various ptocedures such Shodhana, marana .
