Background
Mentha piperita L. (peppermint) is one of the most widely consumed medicinal herbs that has gained attention from food and pharmaceutical industries due to its distinct aroma and taste.
Conclusions
The current study validated the preventive and curative potential of Mp.Cr against urolithiasis and justified its traditional use in kidney stone disease.
Purpose
Present study was aimed to rationalize the traditional use of peppermint in urolithiasis and to explore its possible underlying mechanism. Research Design: The aqueous methanolic crude extract of Mentha piperita (Mp.Cr) was assessed for phytochemical constituents and antioxidant activity. In vitro crystallization assays were performed to determine the inhibitory effects of Mp.Cr against crystal nucleation, aggregation and growth. In vivo urolithiasis model was developed in rats by the administration of ammonium chloride and ethylene glycol in drinking water. The antiurolithic effects of Mp.Cr were evaluated by analyzing kidney homogenate, biochemical and histological parameters.
Results
HPLC analysis showed the presence of epicatechin, quercetin, gallic acid, syringic acid, kaempferol, caffeic acid and coumaric acid. The maximum quantity of quercetin equivalent flavonoid and gallic acid equivalent phenolic content was found to be 63.73 ± .24 mg QE/g and 43.76 ± .6 mg GAE/g of Mp.Cr, respectively. Mp.Cr significantly normalized urinary and serum biochemistry, similar to the standard cystone treatment. Conclusions: The current study validated the preventive and curative potential of Mp.Cr against urolithiasis and justified its traditional use in kidney stone disease.
