Key Phytochemical Constituents
- Randianin (saponin)
- Dumetoronins A-F (saponins)
- Randoside A (glycoside)
- 10-Methylixoside (iridoid glycoside)
- Ursosaponin
- Randia acid
- Tartaric acid
- Citric acid
How does it work?
- Emetic: Saponins (randianin, dumetoronins) irritate gastric mucosa and stimulate the chemoreceptor trigger zone (CTZ), inducing therapeutic emesis (Vamana)
- Anti-inflammatory: Iridoid glycosides and triterpenoid saponins suppress IL-1beta, TNF-alpha production, and inhibit COX-2 expression
- Immunomodulatory: Saponins and glycosides enhance phagocytic function and modulate adaptive immune response through T-helper cell modulation
Which traditional uses are supported by research?
- Therapeutic emetic use (Vamana) validated by saponin-mediated gastric mucosal irritation and CTZ stimulation
- Anti-inflammatory use for respiratory disorders supported by IL-1beta reduction in human lung epithelial cells
- Wound healing activity confirmed through antimicrobial and collagen synthesis promotion in excision wound models
What do recent clinical trials show?
3 further claims previously listed here could not be traced to a published paper and have been removed. An absence here means we could not identify the source, not that no work exists.
Recent safety updates
- Used therapeutically for Vamana (emesis) in Panchakarma; must be administered only under supervision of trained Ayurvedic practitioner to avoid dehydration and electrolyte imbalance
- Not for unsupervised self-medication; excessive use may cause severe vomiting, nausea, and abdominal pain; contraindicated in pregnancy, debilitated patients, and children under 5
What is it made of?
Key Active Markers
- Saponins
- Citric Acid
- Randianin
- Dumetoronins A-F
- Randoside A
- Ursosaponin
- Randia acid
- Tartaric acid
Analytical Methods: HPLC fingerprinting, TLC (identity), LC-MS/MS (marker quantification)
Dosage forms and preparation
Dosage Forms: Churna (powder), Kwatha (decoction), Pippali-Madanaphala yoga (combination), Capsules, Tablets (for sub-emetic doses), Lepa (topical)
Standard Dosage: Emetic dose: 3-6 g powder with honey and rock salt for Vamana therapy. Sub-emetic dose: 500 mg-1 g for expectorant effect. External use as paste.
Bioavailability: Saponins are moderately absorbed orally; emetic effect is primarily local on gastric mucosa via vagal stimulation. Randiasaponins show limited systemic bioavailability which is therapeutically appropriate as primary action is emetic/expectorant. Hepatic metabolism is rapid for absorbed fractions.
Optimal Timing: Early morning on empty stomach for Vamana procedure; before meals for expectorant effect; specific timing as per Panchakarma protocol
Standardized Extract: Shodhita (purified) fruit powder standardized to 4-6% total saponins (as randiasaponin equivalents). Sub-emetic extract (2:1 aqueous) with controlled saponin content of 2-3% for expectorant formulations.
Shelf Life: 24 months for Shodhita powder; 30 months for tablets/capsules; 18 months for decoction concentrate
Storage: Store below 25 deg C in airtight containers. Protect from moisture as saponins are hygroscopic. Keep in restricted access storage due to emetic potency. Label clearly with ‘For Practitioner Use Only’ for Vamana preparations.
Marker Compounds: Randiasaponin I-IV, Randianin, Ursolic acid, Oleanolic acid, Saponin glycosides, Mannitol
Extraction Methods
- Aqueous extraction (for emetic preparations)
- Hydroalcoholic extraction (50% ethanol)
- Saponin-enriched extraction using butanol partitioning
- Traditional processing with Phanita (sugar syrup) for Shodhana
Synergistic Combinations
- Pippali (Vamana Dravya combination)
- Vacha (emetic potentiation in Panchakarma)
- Yashtimadhu (emetic with gastric protection)
- Nimba (antiparasitic combination at sub-emetic doses)
- Madhu/Honey (traditional vehicle for emetic use)

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.
