Traditional uses

On the Greek island of Chios, mastic has been harvested and prized for thousands of years, so much so that Ottoman rulers once guarded its trade closely. Ancient Greeks and Romans chewed the hardened resin tears to sweeten the breath and calm an unsettled stomach, a habit that gave us the very word 'masticate.' Beyond the body, mastic found its way into incense, varnish, and the kitchens of the eastern Mediterranean, where it still lends its resinous, pine-like sweetness to breads, puddings, and the stretchy Turkish ice cream called dondurma.

Did you know?

Chios is the only place on Earth where mastic resin forms naturally into those clear amber tears, a quirk of soil and climate so particular that cuttings of the very same tree, planted just a few miles away on the mainland, refuse to weep the resin at all.

Safety

Mastic is well tolerated in normal culinary and traditional amounts. It belongs to the cashew family, so those with tree nut or pistachio allergies should be cautious, and it is best avoided during pregnancy and breastfeeding since safety data is limited.
