Therapeutic Actions (Karma)
How is it used traditionally?
Name means ‘fire churner’ — stimulates digestive fire. One of ten roots in Dashamoola. Used for Shotha (inflammation), Agnimandya (weak digestion), and Amavata (rheumatoid arthritis).
Where is it described in the classical texts?
- Charaka Samhita (Shothaghna group)
- Sushruta Samhita
Recommended Dosage
Root powder: 3-6g/day; Decoction: 50-100ml/day
Safety, contraindications and cautions
- Pitta conditions
- Pregnancy
What is it made of?
Part(s) Analyzed: Root, Bark, Leaf
Dosage forms and preparation
Dosage Forms: Churna (powder), Kashayam (decoction), Kwatha tablet, Capsule, Asava-Arishta (fermented preparation), Guggulu combination
Standard Dosage: 3-6g powder twice daily; 50-100ml decoction twice daily; 500mg-1g extract capsule
Bioavailability: Moderate bioavailability. Key bioactives (flavonoids, lignans, iridoid glycosides) show reasonable oral absorption. Prematurrins and 5-hydroxymethylfurfural are well absorbed. Enhancement via piperine co-administration increases bioavailability by 30-40%. Ghee as anupana facilitates lipophilic constituent absorption.
Optimal Timing: Before meals with warm water for metabolic and digestive indications; with Dashamoola kwatha for inflammatory conditions
Standardized Extract: Standardized to minimum 2.5% total flavonoids (as 5-hydroxymethylfurfural equivalent). Root bark extract with minimum 1% prematurrins.
Shelf Life: 2 years (powder); 3 years (tablets/capsules); 5 years (Asava-Arishta)
Storage: Cool, dry place below 25°C, RH < 60%. Protect from light. Asava-Arishta in amber glass bottles at room temperature.
Marker Compounds: Premnatriol, Prematurrins A-D, 5-Hydroxymethylfurfural, Iridoid glycosides, Agnuside, Beta-sitosterol
Extraction Methods
- Aqueous decoction (1:16, reduced to 1/4)
- Hydroalcoholic extraction (70:30 ethanol-water)
- Supercritical CO2 extraction for terpenoid enrichment
- Sequential extraction (hexane → ethyl acetate → methanol → water)

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.
