Butea monosperma
Butea monosperma is an Ayurvedic herb containing flavonoids like butein and butin that exhibits nephroprotective and anti-inflammatory properties. The plant modulates inflammatory pathways and oxidative stress markers in preliminary studies.

Origin & History
Butea monosperma is a medium-sized deciduous tree native to the Indian subcontinent, particularly found in forests like those in Jabalpur, India, belonging to the Fabaceae family. Extracts are typically prepared from the leaves, flowers, bark, and seeds using ethanol or water extraction methods.
Historical & Cultural Context
Butea monosperma holds prominence in Ayurvedic medicine as a versatile phytomedicine, used historically for anti-inflammatory, anticancer, wound healing, antidiabetic, and nephroprotective purposes. Traditional applications span centuries in Indian traditional systems, with bark, leaves, flowers, and seeds employed therapeutically.
Health Benefits
• Kidney protection: Ethanolic leaf extract (400 mg/kg) significantly reduced markers of kidney damage in animal studies (P<0.001) - Preliminary evidence only • Anti-inflammatory effects: Flower extract suppressed inflammatory markers (IL-6, MMP-3, MMP-9, MMP-13) in osteoarthritis cell studies - In vitro evidence only • DNA protection: Leaf extracts reduced genetic damage markers by up to 80% in mice exposed to chemotherapy drugs - Animal studies only • Bone health support: Bark extract promoted bone cell development via Wnt/β-catenin pathway activation - Cell culture evidence only • Antioxidant activity: Extracts reduced oxidative stress markers and increased glutathione levels in multiple animal models - No human data available
How It Works
Butea monosperma's flavonoids, particularly butein and butin, inhibit inflammatory mediators including IL-6, MMP-3, MMP-9, and MMP-13 in cellular models. The ethanolic leaf extracts appear to reduce oxidative stress markers and modulate kidney function parameters. These compounds likely work through antioxidant pathways and matrix metalloproteinase inhibition.
Scientific Research
All available evidence for Butea monosperma is limited to preclinical animal and in vitro studies, with no human clinical trials, RCTs, or meta-analyses identified. Key studies include nephroprotection in rats (n=20-25 per group), anticlastogenic effects in mice (n=3-6 per group), and cell culture work on osteoarthritis chondrocytes and cancer cells.
Clinical Summary
Current evidence is limited to animal and cellular studies with no human clinical trials available. Animal research using 400 mg/kg ethanolic leaf extract showed significant reduction in kidney damage markers (P<0.001). Cell culture studies demonstrated suppression of inflammatory markers in osteoarthritis models. The preliminary nature of these findings requires validation in human subjects before therapeutic claims can be substantiated.
Nutritional Profile
Butea monosperma (Flame of the Forest) contains bioactive compounds across multiple plant parts. Flowers: flavonoids including butrin (0.5–1.2% dry weight), isobutrin, butin, and coreopsin; chalcones such as butein and isobutein. Seeds: contain fixed oils (~18–20% by weight) rich in palmitic, oleic, and linoleic fatty acids; toxic alkaloids including monospermine; lectins with hemagglutinating activity. Bark: tannins (~8–12% dry weight), palasonin (a anthelmintic principle), and β-sitosterol. Leaves: flavonol glycosides, medicarpin (a pterocarpan), and cajanin; crude protein approximately 12–15% dry weight in leaf meal; crude fiber ~18–22%. Roots: isoflavonoids including prunetin and biochanin-A. Gum (Palash gum): polysaccharide-rich (~70–80%), composed of arabinose, galactose, and glucuronic acid residues. Minerals detected in leaf extract: iron (~180 mg/100g dry weight), calcium (~1,200 mg/100g), zinc (~12 mg/100g), and phosphorus (~300 mg/100g) — values are approximate from regional phytochemical studies. Bioavailability notes: butrin and isobutrin show moderate oral bioavailability in animal models; palasonin is poorly absorbed systemically but acts locally in the GI tract; flavonoids undergo hepatic conjugation reducing systemic availability; seed lectins are denatured by heat, limiting bioactivity in processed preparations. Note: Most compositional data derives from Indian subcontinent plant specimens; significant variability exists based on soil, season, and plant part.
Preparation & Dosage
Animal studies used ethanolic leaf extract at 200-400 mg/kg body weight daily for 7-8 days. No human dosage data is available. Chronic seed powder administration showed reproductive toxicity in rats after 3 months. Consult a healthcare provider before starting any new supplement.
Synergy & Pairings
Turmeric, Ashwagandha, Boswellia, Ginger, Triphala
Safety & Interactions
Safety data for Butea monosperma supplementation is extremely limited with no established dosing guidelines for humans. Potential interactions with medications metabolized through liver enzymes remain unknown. Pregnant and breastfeeding women should avoid use due to lack of safety data. Individuals with kidney conditions should consult healthcare providers before use given the herb's effects on renal parameters.
