Plantago Lanceolata (Ribwort Plantain) Leaf Extract
What is Plantago Lanceolata (Ribwort Plantain) Leaf Extract?
Plantago lanceolata, known as ribwort plantain, is a perennial herb in the Plantaginaceae family, native to Europe and naturalized worldwide. Its leaves are extracted using water, glycerin, or alcohol to yield a concentrated liquid rich in mucilage, flavonoids like baicalein and luteolin, iridoids such as aucubin, and phenolic compounds. In cosmetics, it serves as a botanical extract primarily in the skin conditioning and antimicrobial categories. The extract works by delivering these bioactives that interact with skin microbes to limit proliferation, while mucilages form a hydrating film for protection. Commonly added to emulsions, cleansers, and masks, it enhances formula stability and provides subtle soothing through barrier support without heavy emollience.
