Cirsimarin is a natural flavonoid glycoside extracted from plants like Primula species, known for its potent antioxidant, anti-inflammatory, and hepatoprotective properties. It is primarily used in dietary supplements and pharmaceutical research to support liver health, protecting hepatic cells from toxins, alcohol-induced damage, and oxidative stress. Studies suggest it may also aid in reducing inflammation and supporting digestive function. In cosmetics, it is incorporated as a niche ingredient in anti-aging formulations for its antioxidant benefits, helping to combat skin oxidative damage, though it is not a common commercial additive.
