In this present study, Karpura shilajit bhasma, an Ayurvedic herbo-mineral formulation, currently used in the Ayurvedic clinical practice as a diuretic drug, was investigated chemically and pharmacologically. Content of iron and nitrogen were determined by volumetric analysis and content of calcium, magnesium and aluminium by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). LD 50 , gross behavioral studies and diuretic activity were evaluated in experimental animals. Calcium

Karpura shilajit bhasma produced mild reduction in motor coordination and mild sedation during the first 2 h after administration at the doses of 500-5000 mg/kg p.o. in mice. The diuretic activity was found to be significant (P < 0.01) at minimum dose of 200 mg/kg p.o. in rats and dose dependant up to 1000 mg/kg p.o. Furthermore, natriuretic effect was found to be significant (P < 0.01), while no significant change was observed on urinary potassium excretion. The present study justified the use of Karpura shilajit bhasma as a diuretic drug. The results of this study could be used as a model data in the standardization of Karpura shilajit bhasma. Afr. J.
