(2018): This phase 2 randomized, double-blind, placebo-controlled trial tested Urox (containing Crataeva nurvala stem bark extract) in 150 participants with overactive bladder symptoms. It showed significant reductions in incontinence episodes (up to 40%) and urgency after 8 weeks, attributed to improved bladder tone and capacity (Schoendorfer, N., et al., 2018, BMC Complementary and Alternative Medicine).
2. Jahan et al. (2023): In a study on 2K1C hypertensive rats, Crataeva nurvala bark extract normalized uric acid and creatinine levels, restored antioxidant enzymes like catalase and SOD, and upregulated genes such as Nrf2 and HO-1 in kidneys, preventing oxidative stress and organ damage (Halder, S., et al., 2023, Oxidative Medicine and Cellular Longevity).
3. Auwal et al. (2014): Ethanolic extracts of Crataeva nurvala bark were evaluated for nephroprotective effects in gentamicin-induced nephrotoxic rats, demonstrating reduced serum creatinine and BUN levels by 30-50%, linked to its antioxidant polyphenols (Auwal, M. S., et al., 2014, Journal of Ethnopharmacology).
4. Moniruzzaman et al. (2018): Methanolic leaf extracts of Crataeva nurvala were tested in mice for anxiolytic effects using elevated plus maze and light-dark box tests, showing dose-dependent increases in open arm time (up to 60%) and transitions, possibly via GABAergic modulation (Hossain, M. S., et al., 2018, Clinical Phytoscience).
5. Varma et al. (2011): In an experimental study on urolithiasis in albino rats, Varuna decoction increased urinary output and promoted hypercalciuria and hyperphosphoruria, reducing stone formation by 25-35% through metabolic correction (Varma, R., et al., 2011, Ayurveda Journal).
