Introduction: In Ayurveda, metals and minerals are converted into biocompatible forms through specified classical procedures like Shodhana, Marana, etc. before their therapeutic use. Their frequent use without any noticeable side effects since ages is the ultimate proof of safety. But, safety and toxicity concerns are being raised by conventional researchers considering the presence of heavy metals in them. Noncompliance of pharmaceutical procedures as described in Ayurvedic classics is one possible cause for toxicity. At the same time, no standard analytical profiles are available for many metallic preparations.
Materials and methods:The present study aims to prepare and develop preliminary analytical profiles for Tamra bhasma (calcined copper) with and without Amritikarana on structural and elemental basis to address the role of the raw materials used during the preparation, compound form, nature and particle size of both samples.
Results and conclusion:The study revealed that Tamra Bhasma contains copper in a nano-crystalline structure having standard mean diameter ~12.72 μ in Tamra bhasma without Amritikarana and ~8.83 μ in Amritikarana sample. Copper sulfide form (CuS) associated with elemental sulfur was found to be a structural component in both samples.
