Rasashastra is a subject which deals with metals and its therapeutic effect. It mentions the use of metals in a refined form as bhasma. Loha is used extensively in the Ayurvedic literature for the management of various diseases like Pandu (Anemia), Shotha (Oedema), Kamala (Jaundice) etc. It is very hard metal hence it should be made into bhasma for using it for medicinal purposes. Iron fillings are subjected to samamnya shodhana and vishesha shodha to prepare the bhasma. Pharmaceutical and analytical studies were conducted during the process of preparation of the Loha bhasma to know the changes in the chemical composition at various satges. Namburi Phased Spot Test was done to prove the fineness of the bhasma. In this study an attempt has been made to standardize the process of the preparation of the Loha bhasma and to establish chemical standards like iron content in the bhasma and the Namburi Phased Spot Test.
