It also finds application in the pharmaceutical sector, where it is studied for its potential antioxidant, anti-inflammatory, and hepatoprotective properties, making it a candidate for inclusion in dietary supplements and health products. Additionally, its role in skincare formulations is being explored, as it may help protect against oxidative stress and improve skin health.
