Phytochemical Composition
The therapeutic potential of *Crataeva religiosa* is attributed to its diverse bioactive secondary metabolites:
- Triterpenoids and Phytosterols: Lupeol, beta-sitosterol, and varunol.
- Flavonoids: Quercetin and rutin derivatives.
- Glucosinolates: Epifriedelin and allied active principles responsible for lithotriptic activity.
Pharmacological Activities & Therapeutic Efficacy
Lithotriptic and Anti-Urolithiatic Effects
- Mechanism: Active isolates like lupeol promote the dissolution of urinary calculi by modifying urinary pH, reducing stone-forming constituents like calcium oxalate, and flushing out crystalline aggregates through enhanced diuresis.
- Scientific Evidence: Experimental animal studies validate that administration of stem bark extracts significantly inhibits urolithiasis and reduces urinary risk factors.[3]
Diuretic and Anti-Inflammatory Actions
- Mechanism: The plant extract stimulates renal blood flow, leading to increased urine output while suppressing acute inflammatory pathways in the urinary epithelium.
- Scientific Evidence: Preclinical models confirm its significant diuretic profile and capacity to reduce soft-tissue edema and inflammatory exudates.[4]
Safety, Toxicity, and Dosage
- Acute Toxicity: *Crataeva religiosa* stem bark extracts demonstrate a high safety margin with no adverse toxic effects observed at standard therapeutic dosages.
- Precautions: Use with caution in severe dehydration or acute renal failure unless administered under professional medical guidance.
