 The production of herbo-mineral or mineral medicines
needs immense power that cannot be generated by
hitherto techniques.
 Therefore, the ayurvedic physicians have devised
special yantras that generate immense heat to treat the
minerals at high temperatures.
 Yantra is an appliance or mechanical contrivance that
helps ‘purify’ raw minerals and formulate medicines of
bio-mineral substances.

 Tens of varieties of yantra were described in medieval
ayurvedic texts.
 These yantras are made out of simple earthen ware,but
subjected to intense heat during few days.
 The mercury and other alchemical products that are
bound within yantras undergo metamorphosis under
duress and yield final product in very fine form.
