The origins of clary sage lie in the Mediterranean region. The Latin name for clary sage is Salvia sclarea, which comes from the word clarus. Clarus means clear. The name comes from the plant’s effectiveness for removing dust and other foreign particles from the eye. It is used for this purpose because the seeds are mucilaginous, similar to chia and flax seeds. This means that clary seeds create a thick, slimy fluid when you soak them in water. You can use that fluid to wash the eyes. This herb has been used as an eyewash and in cooking since the 4th century BCE. Clary sage was documented by Greek philosopher Theophrastus as well as by 1st century CE Roman naturalist Pliny the Elder.
Clary sage was used for its medicinal properties throughout the Middle Ages in Europe. The 17th-century herbalist Nicholas Culpeper suggested dipping clary sage leaves in batter and frying them in butter. According to him, the fried leaves helped with back pain. He also warned about mixing the clary sage leaves with wine as he believed the combination acted as an aphrodisiac.
