The discovery: a plant venerated since Antiquity
Salvia sclarea is one of the oldest species of the Lamiaceae family, already mentioned in the writings of Dioscorides, a Greek physician of the 1st century, for its medicinal virtues. However, it was the famous Swedish botanist Carl Linnaeus, in 1753, who described it for the first time in his work Species Plantarum, laying the foundations for the modern classification of plants. Clary sage, cultivated since Antiquity in the Mediterranean basin, has long been used as a medicinal and aromatic plant.
