Chios mastic has a long history and many uses. So this page works as a starting point. Each section links to a deeper guide if you want more detail.
What is Chios mastic?
Chios mastic is the hardened sap of the mastic tree (Pistacia lentiscus var. Chia). Growers score the bark by hand, and the resin weeps out. It then dries in the sun into small drops called tears. The tree yields this prized resin only in southern Chios. That single origin is why the resin is famous. It even holds protected status in the European Union. To learn how to spot the real thing, see our guide to authentic Chios mastic gum.
What is Chios mastic good for?
Chios mastic has several well-known uses. Most people chew it for fresh breath and everyday oral care. The chewing also gives the jaw a natural workout. So many people use it for jaw and masseter training. In the kitchen, ground mastic flavors breads, sweets, and ice cream. It has also been valued for digestive support since ancient times.

How do you use Chios mastic?
There are two main ways to use it. The first is chewing. Take one or two small tears, let them warm, then chew until they soften into a smooth gum. The second is cooking. Grind the resin with a pinch of sugar, then add a little to your recipe. A small amount goes a long way. For step-by-step chewing, see how to chew mastic gum small tears. For recipes, see our Chios mastic gum small tears guide.
Is Chios mastic safe to consume daily?
For most people, yes. Chios mastic is a natural food that people have consumed for thousands of years. It is a single ingredient with nothing added. So daily chewing or cooking is generally fine in normal amounts. Still, a few people should take care. Mastic comes from a relative of the pistachio, so anyone with a tree nut allergy should be cautious. If you are pregnant or managing a health condition, check with your doctor first.

Real Chios mastic is a premium product, so it is not the cheapest resin on the market. Prices vary by grade and quantity. Small tears are the most affordable grade, while large tears cost more.

What size mastic tears should you buy?
The right size depends on how you plan to use it. Small tears are soft, affordable, and easy to chew or grind. Medium tears are firmer, which suits jaw training.
