Effect of an Ayurvedic compound preparation on the ability of rat urine to influence mineral phase formation.

ABSTRACT

Rat urine could inhibit not only the in vitro initial precipitation of calcium and phosphate/oxalate ions as mineral phase but also the subsequent growth of the preformed mineral phase. Oral administration of the aqueous extract of a commercially available Ayurvedic compound preparation to rats, was found to significantly increase the ability of the urine samples to inhibit both the initial mineral phase formation and its subsequent growth.
