Clary sage (Salvia sclarea) is a biennial or short-lived perennial herb in the Lamiaceae family, native to the Mediterranean region and western Asia. It has broad, softly textured leaves and tall flower spikes with fragrant bracts, and the leaves and flowering tops are the parts traditionally used.

Traditionally, clary sage has been used in calming herbal preparations, aromatic household use, and old-fashioned eye washes in historical texts. Today it is best known as a fragrant garden herb and as the source plant for clary sage essential oil.
