Actions and Clinical Relevance:The Aervanone and Aervine alkaloids are the cornerstone of the plant's potent Antiurolithiatic activity. They employ a multi-mechanistic approach:
Crystallization Inhibition: They alter the surface charge and thermodynamics of calcium oxalate crystals, preventing their nucleation, growth, and aggregation into stones.
Diuresis: They stimulate kidney function, increasing urine volume to flush out micro-crystals before they can form stones.
Anti-inflammatory & Analgesic: They reduce the inflammation and pain in renal tissues caused by the sharp edges of crystals and urinary obstruction.These alkaloids are prime candidates for the development of a standardized, natural anti-kidney stone drug.

2. Flavonoids: The Multi-Targeting Antioxidants

Key Compounds: Vitexin, Isovitexin, Kaempferol, Quercetin, Luteolin, and their glycosides (e.g., Kaempferol-3-O-rutinoside).
Actions and Clinical Relevance:This group provides broad-spectrum antioxidant support and targeted therapeutic actions.
Vitexin and Isovitexin (C-glycosylflavones): Beyond strong antioxidant activity, they exhibit notable Anti-inflammatory and Antidiabetic potential. Vitexin inhibits α-glucosidase and α-amylase enzymes, slowing carbohydrate digestion and managing post-prandial blood sugar levels. Their C-glycosidic bond also enhances metabolic stability.
Kaempferol and Quercetin (O-glycosylflavonols): These universal phytochemicals possess robust antioxidant, anti-inflammatory, and diuretic properties. They protect renal cells from oxidative stress induced by hyperoxaluria.
Phytosynergy: Certain flavonoids may inhibit drug-metabolizing enzymes, potentially enhancing the bioavailability and efficacy of other co-compounds within the plant.
