Lithiasis was induced by oral administration of ethylene glycolated water (0.75%) in adult male wistar albino rats for 28 days. Treatment with ethanolic root extracts of S.spontaneum (200 and 300 mg / kg body weight) in group III and IV significantly (p< 0.05) in urolithiatic rats. Treatment with plant extract restored the levels and it brought back the values to near normal range in urolithiatic rats.
