What is Symphytum Officinale (Comfrey) Leaf Extract?

Symphytum officinale, commonly known as comfrey, is a perennial flowering herb native to Europe and parts of Asia. The leaf extract is derived from its leaves through aqueous or solvent extraction and serves as a botanical ingredient in cosmetics, especially hair care products like shampoos and scalp treatments, as well as skin formulations. It functions via key compounds such as allantoin, which aids fibroblast activity for tissue support, and mucilage that forms a hydrating barrier to calm discomfort. Rosmarinic acid contributes mild antimicrobial action. In products, it typically acts as a soothing and antidandruff agent by fostering a balanced scalp environment and reducing visible flaking. However, presence of pyrrolizidine alkaloids necessitates careful use to minimize absorption risks through skin.
