According to a study published by "International immunopharmacology", Stellera chamaejasme L. has been traditionally used to treat skin-related diseases such as psoriasis and skin ulcers. A novel flavonoid isolated from its aerial parts, named stechamone, was found to most potently inhibit IL-4 production and mast cell degranulation in RBL-2H3 cells. Topical application of 0.5% stechamone improved atopic skin symptoms like erythema, pruritus, exudation, excoriation, and lichenification in DNCB-treated AD mice. This treatment also attenuated DNCB-induced increases in IL-4 expression and in serum IgE levels. Ultimately, stechamone demonstrated strong anti-atopic activity by regulating skin barrier function and reducing inflammatory responses.
