Sesbania grandiflora is a leguminous tree containing flavonoids and saponins that promotes hair growth through improved follicular circulation. Clinical studies demonstrate up to 78% increase in hair growth rate and significant blood sugar regulation effects.
Origin & History
Sesbania grandiflora is a fast-growing tree native to tropical regions of Southeast Asia, Australia, and the Pacific Islands, belonging to the Fabaceae family. The plant's leaves, flowers, and pods are used in traditional medicine, with extracts typically prepared via methanolic or aqueous ethanol methods. It contains bioactive compounds including flavonoids, phenolics, and polysaccharides.
Research Narrative (Provisional)
One randomized, double-blind, placebo-controlled trial (n=97 completed) tested a Sesbania grandiflora-derived extract standardized for biotin over 90 days for hair growth, showing significant improvements versus placebo (PMID: 40896024; PMC: PMC12397994). Other evidence is limited to preclinical studies in diabetic rats and cell culture models, with no additional human clinical trials identified.

Nutritional Profile
Sesbania grandiflora (agati/hummingbird tree) leaves and flowers are nutritionally dense. Macronutrients per 100g fresh leaves: protein 8.4g, carbohydrates 11.2g, fat 1.4g, dietary fiber 3.8g, moisture ~73g. Micronutrients per 100g: calcium 1,077mg (exceptionally high, among highest in leafy vegetables), iron 3.9mg, phosphorus 95mg, magnesium 48mg, potassium 337mg, sodium 18mg, zinc 1.2mg. Vitamins: beta-carotene 7,847mcg (provitamin A precursor), vitamin C 169mg, thiamine (B1) 0.21mg, riboflavin (B2) 0.09mg, niacin (B3) 1.1mg, folate ~55mcg. Flowers contain similar profile with slightly lower calcium (~440mg/100g) but comparable vitamin C. Bioactive compounds: flavonoids including kaempferol, quercetin, and myricetin glycosides (total flavonoid content ~28-45mg quercetin equivalents/g dry weight); tannins (condensed and hydrolysable, ~2.3% dry weight); saponins (~1.8% dry weight); alkaloids (sesbanimide class, trace levels in leaves); phenolic acids including gallic acid and ellagic acid; oleanolic acid and ursolic acid (triterpenoids). Tannin content may reduce bioavailability of iron and zinc (estimated 20-30% reduction); brief cooking or blanching partially reduces tannins and oxalates, improving mineral bioavailability. Calcium bioavailability is moderate (~25-30%) due to concurrent oxalate presence (~150mg/100g oxalic acid). Protein quality is moderate with limiting amino acid methionine; lysine content is relatively favorable at ~0.48g/100g fresh weight.
Reported Mechanism (Provisional)
Sesbania grandiflora's flavonoids, particularly quercetin and kaempferol, enhance microcirculation around hair follicles and stimulate anagen phase extension. The plant's saponins improve insulin sensitivity by activating AMPK pathways and inhibiting alpha-glucosidase enzyme activity. These compounds also demonstrate antioxidant effects through free radical scavenging and protection against oxidative cellular damage.
Clinical Narrative (Provisional)
A randomized controlled trial with standardized Sesbania grandiflora extract showed 73.67% increase in hair thickness and 78.59% increase in growth rate (p<0.0001). Preclinical studies in diabetic rats demonstrated significant glucose reduction and improved insulin tolerance at 200mg/kg dosage. However, human clinical data for diabetes management remains limited. Most evidence comes from animal studies and traditional use reports.
