Pure Amarelli licorice. Licorice (Glycyrrhiza glaba) is a leguminous plant typical of the Ionic coastal area of Calabria. The juice extracted from licorice root has been known since ancient times for its therapeutic properties. As far back as 1500 the Amarelli family from Rossano Calabro sold licorice root that grew spontaneously on their land. It was the Amarellis who founded the “concio” or facility for the extraction of the juice which was then cooked and reduced to a very aromatic, shiny black paste.
