People have known about Chios mastic since ancient times. It comes from the resin of the mastic tree, a very widespread plant on the island of Chios, in Greece. With its abundance of properties, this product finds applications in various sectors, including phytotherapy, cosmetics, and food.

Let’s delve into more details about this natural substance, which serves as an effective remedy for preventing gastric reflux.

What is Chios Mastic?

Chios mastic gum, often referred to simply as “mastic,” is a rare resin with a rich history and a range of applications. This natural product is derived from the mastic tree (Pistacia lentiscus var. chia), primarily found on the Greek island of Chios.

The resin has gained global recognition for its distinct properties and versatile uses.

The mastic tree is an evergreen shrub that thrives in the arid Mediterranean climate. It is particularly abundant in the island of Chios, Greece and can reach 4 meters in height. With a tortuous trunk, it has dark, leathery leaves and flowers arranged in spikes that give off a pleasant scent.

However, the mastic tree’s unique feature lies in its ability to produce resin, an exceptional substance highly prized for various purposes.

Chios Mastic: The Resin

Chios mastic is essentially the resin harvested from the mastic tree. Mastic is a natural, aromatic resinous sap, shaped in tears.

To obtain the resin, small incisions are made in the bark of the tree. Around 15 days after the incision, the resin starts leaking, and upon exposure to air, it oozes, acquiring a transparent and yellowish hue. After washing and removing impurities, the resin transforms into a whitish form, ready to be marketed for both medicinal and food purposes.

The resin hardens upon exposure to air, forming translucent, brittle ‘tears’ with a distinctive aroma. This labor-intensive extraction process has been refined over centuries, contributing to the exclusivity and value of Chios mastic.

Chios Mastic Properties

This resin boasts a plethora of properties that contribute to its diverse range of applications in various fields. Here, we explore the key properties that define Chios mastic:

This characteristic makes it valuable in traditional medicine, where it has been used to alleviate inflammation-related ailments. Research suggests that the resin contains compounds with anti-inflammatory effects, offering potential relief for conditions characterized by inflammation.

Antioxidants play a crucial role in neutralizing free radicals, which are linked to various health issues, including aging and chronic diseases. Regular consumption of Chios mastic may contribute to overall health and well-being.

Culinary Use of Chios Mastic

Chios mastic finds widespread application in food production, contributing to both sweet and savory recipes. Its crystals initially possess a bitter taste, but upon chewing, they release a more pungent and balsamic aroma reminiscent of cedar or pine.

It serves as the foundational ingredient for creating Masticha or Mastika, a Greek aromatic liqueur consumed as a digestif, poured over ice cream and fruit salad, used as a cocktail ingredient, or incorporated into pastries (Masticha desserts are highly appreciated in Greece).

In Greece, Chios mastic is also added to lollipops, puddings, milk, spoon sweets, and baked goods, such as Tsoureki, a braided bread consumed traditionally during the Easter period. It is an irreplaceable component in dondurma, the renowned Turkish ice cream.

In Arab countries, it is used to prepare savory dishes with meat or rice and is an ingredient in masticha cheese.

Lastly, it is also present in chewing gums and used to prepare a highly refreshing flavored water.

Other Uses

Beyond culinary and medicinal applications, Chios mastic finds itself employed in various other fields due to its versatile nature.

  • Perfumery: The resin’s aromatic qualities make it a sought-after ingredient in perfumery, contributing a unique and exotic note to fragrances.
  • For Oral Hygiene and Dental Technology: Mastic’s antibacterial properties extend to oral care, making it a valuable component in dental products like toothpaste and mouthwash. Its traditional use as a chewing gum also promotes oral health.
  • Incense: Mastic’s fragrant smoke has been utilized in incense, adding a distinctive aroma to religious ceremonies and rituals.
  • Art and Craftsmanship: The translucent nature of mastic tears has inspired artists and craftsmen. From jewelry to art installations, mastic’s aesthetic appeal transcends its functional uses.

Where to Buy Chios Mastic

This natural product is often available in specialty stores, particularly those focusing on Mediterranean or Greek products. Online platforms provide a convenient way to access Chios mastic from various suppliers, ensuring a reliable source for this precious resin.


While Chios mastic is generally safe for consumption and external use, individuals with known allergies to tree nuts or related substances should exercise caution. As with any natural product, it is advisable to consult with a healthcare professional before incorporating mastic into one’s diet, especially for pregnant or breastfeeding women.


For a long time, Chios mastic has been the primary economic source for the people of Chios. Even today, a significant portion of the income for around 5000 families on the island comes from the cultivation of mastic and its export to the Arab world.

In the past, the importance of this product made the island of Chios a target for conquerors. For this reason, many villages were constructed as true fortresses.

However, the exact moment when this cultivation became famous is unknown. What is certain is that even Hippocrates recommended its use for oral hygiene and health. In ancient Greece, it was a widespread practice to chew Chios mastic to whiten teeth.

Tradition has it that the mastic tree “began to weep” when Saint Isidoros was martyred by the Romans in 250 AD, precisely the same period when it is believed that the people of Chios started the continuous cultivation of mastic.
