Mastiha is a natural resin from the mastic tree on the Greek island of Chios. It is the same thing as Chios mastic gum. People chew it, cook with it, and take it for digestive and oral support. This guide explains what mastiha is, how it differs from regular gum, and what the research says about its benefits.

Mastiha has been used for more than 2,000 years. Today, science is catching up with tradition. So let us look at what mastiha is and what it may do.
What is mastiha?
Mastiha is the hardened sap of the mastic tree (Pistacia lentiscus var. Chia). Growers score the bark, and the resin weeps out. It then dries into small drops called tears. The tree makes this prized resin only in southern Chios. For a full overview of the resin, see our Chios mastic guide.
Is mastiha the same as Chios mastic?
Yes. Mastiha is simply the Greek word for the resin. Mastic is the English word. Both names describe the same product from Chios. You may also see it called mastic gum or mastiha gum. So if a label says mastiha, mastic, or mastic gum, it is the same resin.
How is mastiha different from regular gum?
Regular chewing gum is made from a synthetic gum base. It usually contains sugar, sweeteners, and artificial flavors. Mastiha is different. It is a pure natural resin with a single ingredient. There is nothing added at all. It also starts hard and brittle, then softens as you chew. That natural origin is the main reason people choose it over ordinary gum.
What are the researched benefits of mastiha?
Mastiha has a long history in traditional medicine. Modern studies are now exploring those uses. In fact, the European Medicines Agency recognizes mastiha as a traditional herbal medicine. It is approved there for mild dyspeptic disorders and for minor skin inflammation. Still, research is ongoing, and mastiha is not a proven cure for any condition. Here is what the evidence suggests so far. For a detailed scientific review, see this overview of Chios mastiha and human health.
Digestive and gut support
Mastiha has soothed stomach complaints for centuries. In one 2010 trial, 148 people with functional dyspepsia took mastic gum. Their symptoms, including stomach pain, improved compared with a placebo. Researchers have also studied mastiha against H. pylori, a gut bacterium linked to ulcers. Those results are mixed. Some studies show it reduces the bacteria, while others show no effect. So more high-quality trials are still needed.
Oral health
Oral health has some of the strongest evidence. Chewing mastiha stimulates saliva, which helps rinse the mouth. Small clinical studies also found that it lowered plaque and oral bacteria. Some found reduced gum inflammation as well. That is why many people chew mastiha for cleaner, fresher breath.
Antioxidant activity
Mastiha contains natural compounds with antioxidant activity. Some of these may also help calm inflammation. Scientists have studied these effects in the lab and in small trials. The early findings look promising. However, most of this research is still preliminary.
How do you take mastiha for digestion?
The traditional way is to chew it. Take one or two small tears and chew them into a soft gum. Many people do this after meals or in the morning. You can also grind mastiha and add it to food. If you want to use mastiha for a specific health reason, talk to your doctor first. This is general information, not medical advice.
Where can you buy authentic Greek mastiha?
Authentic mastiha comes only from Chios, so origin matters. Look for a few clear signs before you buy. Choose a product that names Chios specifically. Check that it is a single ingredient with nothing added. Look for lab testing and clear sourcing. For a full checklist, see our guide to authentic Chios mastic gum.
