Dosage forms and preparation
Dosage Forms: Churna (powder), Kwatha (decoction), Taila (medicated oil), Lepa (external paste), Ghana vati (tablet), Resin preparations
Standard Dosage: 3-6 g bark/resin powder per day; 50-100 mL kwatha twice daily; external application of oleoresin as needed
Bioavailability: Triterpenoid and phenolic constituents have moderate bioavailability (20-35%). Oleoresin components are lipophilic and require lipid-based carriers for optimal absorption. Tannins reduce bioavailability of co-administered iron and proteins.
Optimal Timing: After meals for internal use; externally as needed for wound care
Standardized Extract: Bark extract (5:1 in 60% ethanol), standardized to NLT 4% total tannins by Folin-Ciocalteu method; purified oleoresin for external applications
Shelf Life: 24 months for churna; 36 months for resin preparations in sealed containers; 30 months for extract capsules
Storage: Below 25 deg C in airtight containers. Oleoresin in glass or coated metal containers. Protect from light and oxidation.
Marker Compounds: Alpha-amyrin, Beta-amyrin, Ursolic acid, Gallic acid, Ellagic acid, Bergenin
Extraction Methods
- Hydroalcoholic extraction (60% ethanol)
- Aqueous decoction
- Oleoresin tapping and purification
- Soxhlet extraction with ethyl acetate
- Cold maceration in sesame oil for taila
Synergistic Combinations
- Sala (astringent-wound healing synergy)
- Lodhra (hemostatic formulations)
- Arjuna (cardiovascular and wound healing combinations)
- Shallaki (anti-inflammatory resin formulations)
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.
