Bhasma Kalpana is a unique part of Ayurvedic Rasa shastra. It is a method of converting metals into metallic Bhasma. Metallic Bhasmas are well known for its quick effectiveness, smaller dose and a long shelf life. However if these Bhasmas are not well prepared and analyzed they can be toxic to human body. Therefore Bhasma Pariksha is given in Ayurveda to confirm the well prepared metallic Bhasma, but in this era we need to analyze the Bhasmas on modern parameters too to make it acceptable globally. So in this study prepared Rajata (Silver) Bhasma is analyzed on various parameters i.e. Ayuvedic parameters i.e., Varitaratwa, Rekhapurnatwa, Slakshantwa and Laghutwa and some modern parameters like, pH, Particle size, Zeta Potential, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray spectroscopy, Fourier Transform Infra red Spectroscopy (FTIR), U V – Spectroscopy.

Results: pH value is 5.6, UV- spectroscopy showed maximum absorption at 302nm, FT-IR of Rajata bhasma reveals the presence of C-H (alkyl), C-N (Aliphatic amine) groups at different wavelengths, Mean Particle size of Rajata bhasma is 2.7nm, Zeta Potential analysis reveals -19.3 mV, X-RD of Rajata bhasma reaveals the major peaks of HgS (Cinnabar), Ag2S (Silver Sulphide), SEM analysis of Rajata bhasma showed small crystalline particles at 5KX & 10KX magnifications, EDX analysis of Rajata bhasma confirmed the presence of elements viz., Sulphur 20.34%, Oxygen 7.43%, Silver 26.72%, Mercury 45.51% by weight.
