Comprehensive Study of Tamra Bhasma Pareeksha W.S.R Nambhuri Phase Spot Test

Abstract

Introduction: Tamra is a significant metallic drug classified under Dhatu Varga in Ayurveda. Tamra Bhasma, a calcined preparation of copper, holds a prominent place in Ayurvedic therapeutics, particularly for its hepatoprotective and digestive properties. It is widely used in the management of liver disorders such as hepatitis, gallstones, cirrhosis, and hepatosplenomegaly.

Objective: This study focuses on the systematic preparation of Tamra Bhasma and its validation through Bhasma Pariksha (classical organoleptic and physicochemical tests) and NPST to confirm its authenticity and compliance with standard parameters.

Materials and Methods: The preparation of Tamra Bhasma involves a two-stage process: Shodhana (purification) and Marana (incineration).

Ensuring the quality and safety of bhasma preparations is crucial for their therapeutic efficacy. Hence, the final Bhasma sample was evaluated using classical Bhasma Pariksha tests (such as Rekhapurnatva, Varitaratva, Nischandratva, etc.), along with NPST for chemical fingerprinting. The results were compared against the standard values prescribed by the Central Council for Research in Ayurvedic Sciences (CCRAS) guidelines.

Observations and Results: The prepared Tamra Bhasma successfully passed all classical Bhasma Pariksha parameters. The NPST analysis further validated its quality, showing characteristic spot patterns in accordance with CCRAS standards, indicating proper incineration and the absence of toxic residues.

Conclusion: The study demonstrates that prepared Tamra Bhasma meets the classical and modern scientific quality standards. The successful validation through Bhasma Pariksha and NPST reinforces its safety, purity, and therapeutic potential. Standardized preparation methods combined with modern analytical techniques ensure the efficacy and reliability of Tamra Bhasma for clinical applications in hepatobiliary and digestive disorders.
