- Modulates [hormonal balance](/ingredients/condition/hormonal) and supports natural detoxification processes.

## Mechanism of Action

The bean's alkaloids including scoulerine, erysovine, and hypaphorine act as electron and hydrogen donors in ABTS•+ scavenging pathways, achieving TEAC values of 0.46 µmol TE/mg protein post-[digestion](/ingredients/condition/gut-health). Isoflavonoids like erycristagallin inhibit bacterial growth and biofilm formation, while Kunitz-type trypsin inhibitors (ETIa, ETIb) interfere with serine proteinase activity. These compounds collectively reduce intracellular [reactive oxygen species](/ingredients/condition/antioxidant) by up to 75% in cellular models through enzyme inhibition and interference with bacterial incorporation processes.

## Clinical Summary

Current evidence is limited to in vitro and animal studies with no human clinical trials available. Laboratory studies demonstrate significant [antioxidant activity](/ingredients/condition/antioxidant) with FRAP values reaching 522.97 mg AAE/g in water extracts of related Erythrina species. Cell-based research shows up to 75% reduction in ROS levels, while cytotoxicity studies indicate chloroform/methanolic fractions outperformed vincristine sulfate controls in brine shrimp models. The absence of randomized controlled trials represents a significant evidence gap requiring further clinical investigation.
