Bhasmas are the multi elemental drugs derived from natural resources. Physicochemical analysis of various bhasmas supplied by different manufacturers has been reported. Particle size analysis has been done using dynamic light scattering technique. The size of bhasma particle is in the of the order of 1000nm. Chemical analysis of soluble matter of bhasma has been done using inductively coupled plasma – atomic emission spectroscopy technique. Elemental composition of bhasma differs from supplier to supplier. Inductively coupled plasma – atomic emission spectroscopy results show 91.87%, 83.81 and 80.77% soluble matter in tamra bhasma by dhoot, tambra bhasma by Ajit Joshi and swarn makshika bhasma respectively.
Key words: Bhasma, ICP-AES analysis, Dynamic Light Scattering, Nano-particles.
