Mastic is excreted by the resin glands of the evergreen shrub ''
Pistacia lentiscus'' and dries into pieces of brittle, translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to

Hippocrates
Hippocrates of Kos (; ; ), also known as Hippocrates II, was a Greek physician and philosopher of the Classical Greece, classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referr ...
. Hippocrates used mastic for the prevention of digestive problems, colds and as a breath freshener. Romans used mastic along with honey, pepper, and egg in the spiced wine ''
conditum paradoxum''. Under the Byzantine Empire, the mastic trade became the Emperor's monopoly. In the Ottoman Empire, the Sultan gathered the finest mastic crop.
During the
Ottoman rule of Chios, mastic was worth its weight in gold. , the Turkish name for the island of Chios, means 'gum island'. The mastic villages are fortress-like, out of sight from the sea, surrounded by high walls and with no doors at street level (meaning that the villages were entered only by ladders), in order to protect the sap.
Although the liqueur is much younger, it is still tied up with Greek history. Digestive liqueurs, similar to
Mastichato (Mastika), but made with grapes, were known as Greek elixirs before the French Revolution.
The production of mastic was threatened by the
Chios forest fire that destroyed some mastic groves in August 2012.
Cultivation
Producing the mastic resin is a whole-year process for the local growers. The harvest is known as ''kentos'' and takes place from the beginning of July to the beginning of October. First, the area around the trees is cleared and sprinkled with inert
calcium carbonate
Calcium carbonate is a chemical compound with the chemical formula . It is a common substance found in Rock (geology), rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skel ...
. Then, every 4–5 days, 5–10 incisions are made in the bark of each tree to release the resin. As these clear drops hang from the tree, and sparkle in the sunlight, they are said to resemble crystalline teardrops; for this reason, the mastic resin is known as the "tears of Chios". It takes about 15–20 days for the first resin crystals to harden and fall to the ground. The farmers then collect the pieces of dry mastic and wash them in natural spring water, and spend most of the winter cleaning and separating the tears from the sand. This cleaning process is performed by hand and is regulated by the legislative framework of the Mastic Growers' Association. In addition to mastic, mastic oil is also produced.

mastichochoria, or mastic villages, on the island of Chios dedicated to the cultivation and production of mastic.

"3. Name of product: Khios mastic"
The island's mastic production is controlled by a co-operative. Founded in 1938, the Chios Gum Mastic Growers Association (), abbreviated ''CGMGA'', is a secondary cooperative organisation and acts as the collective representative organ of twenty primary cooperatives founded in the twenty-four mastic villages. it has the exclusive management of natural Chios Mastiha in Greece and abroad.
The Chios Mastic Museum offers a permanent exhibition about mastic production on the island, explaining its history and cultivation techniques as well as demonstrating its different uses today.
Turkey
Traditionally there has also been limited production of mastic on the
Çeşme
Çeşme, officially the Çeşme Municipality, is a municipality and Districts of Turkey, district of İzmir Province, Turkey. Its area is 285 km2, and its population is 48,924 (2022). It sits at Turkey's westernmost end, on a promontory on t ...
peninsula, on the Turkish coast eight nautical miles from Chios, with similar ecological conditions suitable for mastic production. The
Turkish Foundation for Combating Soil Erosion, for Reforestation and the Protection of Natural Habitats (TEMA) has led an effort to protect the native Turkish mastic trees and to plant new ones in the Çeşme peninsula to revive viable commercial production of the product. As part of this project, which was expected to last through 2016, over 3,000 mastic tree saplings were planted between 2008 and October 2011 to over 368 acres (149 hectares) of dedicated farm land provided by the
Izmir Institute of Technology.

The EMA concluded that the available clinical studies, though numerous, were too small and methodologically weak to support a "well-established use" designation for mastic resin. These studies primarily investigated its oral (as a sole agent) and cutaneous applications (in combination with other products). Despite these shortcomings, the EMA found that these studies did not raise any significant safety concerns, thus supporting the traditional use of mastic. The assessment highlighted that mastic has been part of traditional and folk medicine for more than 30 years in several countries such as
