Key Phytochemical Constituents
- Catechin
- D-catechin
- Melacacidin
- Beta-sitosterol
- Albiziahexoside
- Betulnic acid
- Echinocystic acid glycosides
- Lebbekosides A-C (saponins)
- Friedelin
- Lupeol
- Tannins
- Flavonoids (quercetin derivatives)
How does it work?
- Anti-allergic activity via catechin-mediated mast cell stabilization (IC50 85 mcg/ml) and inhibition of histamine release from IgE-sensitized mast cells
- Antihistaminic action through suppression of H1 receptor gene transcription and histidine decarboxylase enzyme activity in nasal mucosa
- Anti-inflammatory effects via saponin-mediated (echinocystic acid) inhibition of COX-2, LOX and NF-kB signaling
- Neuroprotective mechanism through modulation of unfolded protein response (UPR) and reduction of ER stress-induced apoptosis
Which traditional uses are supported by research?
- Anti-allergic and anti-asthmatic use validated through mast cell stabilization, antihistaminic activity and clinical studies showing improved PEFR and reduced eosinophil count
- Anti-inflammatory use confirmed in carrageenan-induced paw edema and adjuvant arthritis models
- Vishaghna (anti-toxic) use supported by hepatoprotective and detoxification studies
- Anti-diarrheal activity confirmed through castor oil-induced diarrhea models with significant reduction in frequency

Demonstrated that bark extract suppresses allergic responses at the transcriptional level by inhibiting H1R and HDC mRNA expression and reducing histamine content in nasal mucosa. - Phoraksa O, Chimkerd C, Thiyajai P and others 2023.

Pharmaceuticals (Basel, Switzerland). PMID 37513900 · doi:10.3390/ph16070989
Leaf extract protected human microglial cells from glutamate-induced ER stress and apoptosis through modulation of UPR signaling pathway, suggesting novel neuroprotective applications.

Recent safety updates
- Bark decoction is clinically used in Ayurvedic practice for bronchial asthma with established safety at standard doses
- Saponin-rich preparations may cause GI irritation at high doses; seed powder should be used with caution. Not recommended during pregnancy without supervision.

Key Active Markers
- Catechin
- Sitosterol
- Glycosides
- Saponins
- Friedelin
- Lupeol
- Tannins
- Flavonoids
Analytical Methods: HPLC fingerprinting, TLC (identity), LC-MS/MS (marker quantification)
Dosage forms and preparation
Dosage Forms: Churna (powder), Kwatha (decoction), Capsule, Tablet, Avaleha (confection), Taila (medicated oil), Nasya (nasal drops), Lepa (external paste)
Standard Dosage: 3-6 g bark powder per day; 50-100 mL kwatha twice daily; 500-1000 mg standardized extract capsule twice daily; 2-4 drops nasya oil per nostril
Bioavailability: Saponins (albizia saponins) show moderate oral bioavailability (20-30%). Flavonoids and tannins have typical moderate absorption (25-35%). Histamine-releasing compounds are locally active. Nasya administration provides direct CNS access via olfactory neural pathway — important for anti-allergic and Medhya (cognitive) applications.
Optimal Timing: Before meals for anti-allergic action; nasya in morning on empty stomach after facial steaming; avaleha with honey for respiratory conditions
Standardized Extract: Bark extract (8:1 in 60% ethanol), standardized to NLT 6% total saponins (as oleanolic acid equivalents by HPLC-ELSD); total flavonoids NLT 2% (as catechin equivalents)
Shelf Life: 24 months for churna and capsules; 18 months for avaleha; 24 months for nasya oil
Storage: Store below 25 deg C in airtight containers, protected from light and moisture. Nasya oil in amber glass dropper bottles.
Marker Compounds: Albizia saponin C, Albizia saponin D, Melacacidin, D-catechin, Friedelin, Beta-sitosterol, Echinocystic acid
Extraction Methods
- Aqueous decoction
- Hydroalcoholic extraction (60% ethanol)
- Maceration in sesame oil for nasya preparation
- Soxhlet extraction for saponin enrichment
- Traditional avaleha preparation
Synergistic Combinations
- Haridra (potent anti-allergic synergy — Shirisha-Haridra combination for allergic rhinitis)
- Vasa (asthma and respiratory allergy formulations)
- Pippali (Shvasa-Kasa formulations)
- Yashtimadhu (anti-inflammatory and anti-allergic combination)
- Kantakari (comprehensive anti-asthma formulation)

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.
