Mastic, widely known since ancient times for its beneficial and therapeutic properties, is an aromatic resin offered to us by the mastic tree (Pistacia Lentiscus var. Chia, Anacardaceae family), a shrub flourishing in Southern Chios. Mastic has constituted - and still does - the emblem of the island of Chios, and a large part of the island's growth is attributed to the blessed teardrop of the mastic tree.
