Cystone, a well-known herbal formulation, inhibits struvite crystal growth formation in single diffusion gel growth technique

Objective: The present study was aimed to evaluate the beneficial effect of Cystone against struvite crystal growth in in vitro conditions. Methods: Various concentrations of Cystone was prepared in 1 M magnesium acetate solution and evaluated for crystal growth inhibition assay by a well-known method called single diffusion gel growth technique in vitro. Results: Cystone , a well-known polyherbal formulation, at 0.5, 1 and 2% concentrations showed significant and dose-dependent inhibition of struvite crystal growth formation in in vitro by reducing number, total mass and total volume of the struvite crystals formed and also caused fragmentation of grown struvite crystals in the gel matrix. Conclusion: The results of the present study indicate, Cystone significantly retards the formation of struvite stones and also brings about its fragmentation. This could be one of the probable mechanisms behind the beneficial effect offered by Cystone in the clinical management of urolithiasis and urinary tract infections.
