Mastiha, the unique brand from Chios Island

Mastiha (Greek: Μαστίχα Χίου) is the famous and unique branded product of the Chios island. It is the fifth largest Greek island, located in the North-East Aegean Sea and very close to the Asia Minor coast.

Since 1997, Chios Mastiha has been protected by the European Union as a Protected Designation of Origin (PDO) product.

The origin of Mastiha

The Mastiha (Mastic) grows all over the Mediterranean. But, the special variety tree (Pistacia lentiscus) grows only in the south of Chios island, in 24 villages. They are also called „Mastihohoria“, which means „Mastiha villages“.
The founding of Mastiha villages dates back to the Byzantine era. But the Geno­ans set up the first company for the exploitation of mastic during their rule (1346-1566).

According to the tradition, the Mastic trees began to „shed the tears“, when the Romans took St. Isidore of Chios to be executed, in 251 AD. He was in agonizing pains and wept all the way along the road. His tears fell on the earth and became the fragrant mastic. And this is one of the reasons why mastic is also called „The Tears of Chios“.

Scarce rain, lots of sun and quartz soil texture are the perfect environment for the successful production of Mastic.
One story says that scientists have made an experiment. They brought a mastic tree to the United States and artificially created conditions like those in Chios. The tree was alive, but there was no fruit!


Production of Mastiha

The Mastiha tree is an evergreen shrub and it may be about 2-3 meters high. It grows very slowly and becomes ready for cultivation after 40-50 years. Only this variety produces natural ivory-colored resin or mastic, with specific flavor and aroma.

Mastic production is a complicated and laborious process. The trees are pruned and fertilized every winter.
They begin producing mastic when they are about five years old. Then the villagers clear the ground beneath the trees and cover it with white clay.

The Mastic is contained in the bark, not in the wood. So, during the summer, they make multiple incisions in the branches of the three on specific spots. And the resin starts to flow.

The resin speedily exudes and hardens into oval drops. After two weeks it is ready to be collected.

The collection begins in the middle of August and lasts for about a month. The mastic drops are manually washed, cleaned and sorted, piece by piece. After that, mastic is put onto the wooden boxes and dried in cold places.
The mastic drops are transparent, with a glassy fracture. Their form is like roundish teardrops about the size of peas.

Mastic uses in ancient times

In ancient times Mastiha was used because of its properties that are beneficial to human health.

Hippocrates used it for the prevention of digestive problems, colds and as a breath freshener. Roman emperors used mastic along with honey, pepper, and egg in the spiced wine. Digestive liqueurs made with grapes were known as Greek elixirs.

Also, Mastiha was used as the first natural chewing gum to clean the teeth and freshen the breath in the Roman era and during the Middle Ages. It was even used in cosmetology and as a spice during the Ottoman rule as well.


Mastic uses today

The entire production and cleaning process of Chios Mastiha is free of all chemicals and additives. And this process has remained unchanged over the centuries.
Scientific research has shown that Mastiha resin has anti-oxidant, anti-bacterial, and anti-inflammatory properties.

Mastic is used in the production of a wide range of products and exported throughout the world.
It is a raw material in food products, including baked goods, sweets, ice cream, chocolate, chewing gum, candy, Turkish delight, milk products, pasta, sauces, etc. It is also used as an ingredient for preparing various kinds of drinks, tea, coffee, liquor, ouzo, and wine.

Additionally, Mastic is an ingredient of dietary supplements, oral hygiene products, surgical sutures, compresses burns, dental floss, soap, cosmetics. It is used as an ingredient for the production of scented candles, essential oils, artists’ varnishes, and resin-based adhesives as well. In a word, very impressive, isn’t it?
