Pharmacological evaluation of antiurolithiatic potential in daily foods

Background: Urolithiasis, commonly known as kidney stone disease, is a common and painful urinary disorder caused by the formation of stones in the kidneys, ureters, bladder, or urethra. It mainly occurs due to the crystallization of substances like calcium oxalate, uric acid, cysteine, and calcium phosphate in urine. The condition has a high recurrence rate and may lead to serious complications if untreated. Conventional treatments include increased water intake, medications, and surgical procedures such as extracorporeal shock wave lithotripsy (ESWL). However, these treatments can be costly, painful, and do not always prevent recurrence. Therefore, there is growing interest in natural and plant-based remedies. Methods: This study evaluated the anti-urolithiatic activity of five natural compounds: Ash gourd (Benincasa hispida), Bitter gourd (Momordica charantia), Coconut water (Cocos nucifera), Garlic (Allium sativum), and Apple (Malus domestica). Preliminary phytochemical screening showed the presence of beneficial compounds such as flavonoids, alkaloids, tannins, and terpenoids. In-vitro studies were conducted using nucleation and aggregation assays to examine their effect on calcium oxalate crystal formation. Results: The results showed that all selected compounds significantly reduced crystal formation, especially bitter gourd and garlic, which showed strong inhibitory effects. Conclusion: The study concludes that these natural ingredients may help prevent kidney stone formation and could serve as safer, affordable alternatives to conventional treatment. Further in-vivo and clinical studies are needed to confirm these findings.
