About this ingredient
Sophora Flavescens Root Extract is derived from the roots of Sophora flavescens Aiton, also known as Kushen, a botanical traditionally used in East Asian herbal medicine. The root contains naturally occurring quinolizidine alkaloids such as matrine and oxymatrine, along with flavonoids and other phytochemicals. It is traditionally associated with skin, digestive, and general herbal wellness applications and is also used in some cosmetic formulations. Modern research has investigated its antioxidant, antimicrobial, anti-inflammatory, and other biological properties, but clinical evidence varies and further research is needed.
