Acorus Calamus Root Extract is derived from the rhizome of the calamus (sweet flag) plant and is used in cosmetics for its aromatic, soothing, and traditionally antimicrobial properties. It contains volatile compounds such as beta-asarone, which has raised safety concerns in some regulatory contexts.
