ABSTRACT
Herbal remedies are increasingly being considered as suitable long-term treatments for renal dysfunction. The objective of the present study was to investigate the effect of some herbal extracts, all previously identified in published studies as influencing kidney stone formation, on the crystallization characteristics of calcium oxalate (CaOx) in synthetic urine (SU). Five herbal extracts were selected for the study Folium pyrrosiae, Desmodium styracifolium, Phyllanthus niruri, Orthosiphon stamineus and Cystone(®). Concentrated stock solutions of each herbal extract were prepared and were tested at their recommended dosages in in vitro crystallization studies in SU. CaOx crystallization experiments were performed in which the metastable limit (MSL), average particle size, and nucleation and growth rates were determined. The CaOx MSL of SU was unaltered by the five herbal extracts. Three of the herbs (Desmodium styracifolium, Orthosiphon stamineus and Cystone(®)) significantly reduced the average particle size of precipitated crystals relative to undosed SU. All of the extracts increased the rate of nucleation and decreased the rate of growth significantly in SU. Cystone(®) showed the greatest effect on the measured risk factors. It is concluded that all of the herbs have the potential to serve as inhibitors of calcium oxalate stone formation and warrant investigation in clinical trials.
