Background: Rasashastra is a branch which deals with the pharmaceutics of Rasaoushadhis. Bhasmas are one among such Rasaoushadhis which are known for their low doses and fast action. A verse from Rasaratnasamuchchaya says that the bhasma prepared by using Mercury as media is of best quality. Materials and Methods: Following this principle, Yashadabhasma (Zinc calx) was prepared by subjecting it to Samanya shodhana (general purification method for all metals), Vishesha shodhana (specific putification method for Zinc), Jarana (roasting) and Marana (incineration) with Parada(Mercury) as a media under Gajaputa (classical heating system with 1000 cowdung cakes). Results and Conclusion: Yellow colored Yashadabhasma which passed all the classical bhasmaparikshas (tests for properly prepared calx) was obtained after two putas. The bhasma did not pass Nishchandratva(free from shining particles) test after 1 stputa but was passed after giving it 2 ndputa.
