Kushta Abrak Safaid is a unani formulation used in the treatment of Sual(chronic cough/Bronchitis) and Zeequn Nafas (Asthma), (Anonymous 2006). Kushtajaat (calcines) are organo-mineral fine particles prepared by treating mineral with several herbs and subjected to precise heat treatment. The present study aims at comparing physico-chemical evaluation of Kushta Abrak Safaid prepared by two different methods of detoxification. Abrak was detoxified by two methods as mentioned in Unani literature and their kushtas (calcines) were prepared. Finished products were compared for physico-chemical characteristics. Results suggest that physico-chemical constant of both kushtas were similar without any significant difference.
