In Ayurveda, ‘Lauha’ (Iron) Bhasma is primarily used to cure diseases related to iron deficiency in humans. It is produced from purified raw metallic iron using a combination of multi-step traditional preparation processes described in the Ayurveda literature. Here, we present the results of structural investigation performed on the medicinal grade ‘Lauha’ Bhasma using various X-ray based techniques. Our results indicate that after several rounds of heating and cooling in specific conditions following the Ayurvedic preparation procedure, metallic iron eventually converts to a natural iron-oxide mineral belonging to the magnetite group. Scanning electron microscopy (SEM) and X-ray standing wave assisted fluorescence measurements carried out on powdered Bhasma specimen reveal that the magnetite micro-particles in the Bhasma specimen are usually present in the form of agglomerates of nano-particles. We anticipate that the Ayurvedic Lauha Bhasma has great potential for non-invasive localized target killing of cancer cells, particularly in sensitive parts of the human body such as the brain, spinal cord, and lungs, via necrosis by application of an alternating external magnetic field or photo electron generation through X-rays.

Tamra Bhasma, also known as copper ash, is a traditional Ayurvedic herbo-metallic formulation made by repeatedly calcining (Marana) and systematically purifying (Shodhana) copper to produce a fine, stable, and bioassimilable copper oxide-based ash. It has been used historically for respiratory, metabolic, and hepatic conditions, as documented in books like Rasaratna Samuccaya. Ayurvedic qualities like Lekhana, Deepana, and hepatoprotective effects make it helpful in situations where Pitta and Kapha are aggravated. When properly prepared, conversion into non-metallic oxides or sulphides is confirmed by contemporary analytical studies (XRD, SEM, EDAX), guaranteeing safety. Its authenticity is further confirmed by conventional quality tests like Rekhapurnatva, Nischandratva, and Apunarbhava. Clinical observations point to improvements in chronic cough, Prameha-like conditions, and liver dysfunction. Efficacy and safety are guaranteed by appropriate standardisation and supervised administration. Beyond its traditional medicinal uses, Tamra Bhasma holds a unique place in the Rasashastra tradition because it is a prime example of how precise, multi-stage processing can turn a potentially hazardous metal into a pharmaceutically stable product. According to traditional Ayurvedic texts, copper only loses its metallic sheen, becomes finely particulate, and displays qualities that are compatible with human physiology after undergoing complete Shodhana and repeated Marana. In an effort to characterise this transformation, current research frequently reports structural alterations consistent with copper oxides or mixed oxide phases, indicating that the final product behaves differently from raw metal from a therapeutic perspective, Tamra Bhasma is traditionally described as balancing deranged Kapha and Pitta, supporting Agni, and aiding in the clearance of metabolic by-products (Āma). These findings have sparked renewed scholarly interest in the interface between ancient metallurgical practices and modern material science. It is usually only taken into consideration by modern practitioners within more comprehensive therapeutic frameworks that include individualised assessment, herbal support, and dietary regulation. Furthermore, since preparation errors can seriously compromise safety, responsible use necessitates close adherence to dosage recommendations, authenticity testing, and supervision by qualified Ayurvedic doctors. As a result, Tamra Bhasma continues to be an area of ongoing interdisciplinary evaluation as well as a topic of historical significanceIntroduction Tamra Bhasma, also known as "copper ash," is a traditional Ayurvedic herbo-metallic formulation made from elemental copper that has been purified and repeatedly calcined (marana).
