Vriddhadaru
Argyreia nervosa
Vriddhadaru (Argyreia nervosa) is a plant used in Ayurveda. Friedelin and other triterpenoids have low oral bioavailability (<10%) improved by lipid co-administration. Flavonoids (kaempferol, quercetin glycosides) undergo typical Phase II conjugation with moderate bioavailability (~15-20%).

Dosage forms and preparation
Dosage Forms: Churna (powder), Kwatha (decoction), Capsule, Tablet, Taila (medicated oil), Lepa (paste)
Standard Dosage: 3-6 g powder twice daily; 50-100 mL decoction twice daily; external oil application as needed
Bioavailability: Argyrein (coumarin glycoside) has moderate oral bioavailability (~25-35%) with hepatic hydrolysis releasing the aglycone. Friedelin and other triterpenoids have low oral bioavailability (<10%) improved by lipid co-administration. Flavonoids (kaempferol, quercetin glycosides) undergo typical Phase II conjugation with moderate bioavailability (~15-20%). External application (Taila) allows local absorption through skin for musculoskeletal conditions.
Optimal Timing: After meals for internal use; external oil application at night before sleep for musculoskeletal conditions
Standardized Extract: Root extract standardized to >2% total flavonoids (as quercetin equivalent by UV); >0.5% argyrein by HPLC; ergot alkaloids: absent (mandatory safety test)
Shelf Life: Root powder: 18-24 months; Capsules/Tablets: 24 months; Medicated oil: 18-24 months; Decoction: prepare fresh
Storage: Airtight, moisture-proof containers at 15-25 deg C. Medicated oil in amber glass. Protect from light and humidity.
Marker Compounds: Argyrein, Friedelin, Quercetin, Kaempferol, beta-Sitosterol, Scopoletin, Caffeic acid
Extraction Methods
- Aqueous decoction
- Hydroethanolic extraction (60-70% ethanol)
- Soxhlet extraction with ethanol
- Traditional Taila Paka for medicated oil
- Methanol extraction for coumarin-rich fraction
Synergistic Combinations
- Shunthi (ginger) - anti-inflammatory and digestive synergy
- Ashwagandha - musculoskeletal strength combination
- Bala (Sida cordifolia) - Vata-pacifying musculoskeletal formula
- Eranda Taila (castor oil) - vehicle for Vata disorders
- Guggulu - anti-inflammatory synergy for joint conditions

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.
Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
