Quick answer
What is mastic gum?
Mastic gum is a natural tree resin from Pistacia lentiscus, the mastic tree. The prized form, Chios mastic, comes from the Greek island of Chios, where the resin has been harvested for thousands of years. It has a distinctive pine-cedar aroma and has traditionally been used as a natural chewing gum and culinary ingredient. Today it is taken as a food supplement, usually in capsules. This guide covers what it is and how to judge quality — it makes no health claims.

  • Mastic gum is a resin from the mastic tree, Pistacia lentiscus.
  • The prized source is Chios, Greece — “Chios mastic”.
  • It has been used for millennia as a natural gum and flavouring.
  • As a supplement it's usually pure resin in capsules — strength and origin matter.
  • It's a food supplement; we make no health claims for it.
The basics

What mastic gum actually is

Mastic gum is the dried resin that seeps from the bark of the mastic tree, Pistacia lentiscus, a small evergreen in the same botanical family as the pistachio. When the bark is scored, it weeps droplets of resin known as “tears”, which harden in the sun and are then collected.

It has an unusually long history: it has been chewed as a natural gum, used to flavour foods and drinks, and traded around the Mediterranean since antiquity — the English word “masticate” traces back to it. As a modern supplement it's simply that pure resin, milled and encapsulated.

One of the oldest natural gums in the world — harvested by hand for millennia.
Provenance

Origin & forms

With mastic gum, where it comes from is a genuine quality marker — not just marketing.

Chios mastic
The benchmark. Resin from the mastic trees of southern Chios is the traditional, sought-after source, with protected-origin status in the EU.
Capsules
The usual supplement form. Pure milled resin in capsules, with a stated strength such as 1000mg per serving.
Raw “tears”
The traditional form. Whole resin pieces that can be chewed like gum — authentic, but less convenient than capsules.
Purity matters
Watch for fillers. Good mastic gum is pure resin; cheaper products can be padded out or vague about source.
Buying well

What to look for

Because mastic gum is a premium raw material, quality hinges on purity and provenance.

  • Pure mastic resin — ideally 100% mastic gum, without unnecessary fillers or bulking agents.
  • Clear origin — transparency about the source, with Chios mastic considered the benchmark.
  • A stated strength — e.g. 1000mg per serving, plainly labelled.
  • Independent testing — ISO/IEC 17025-accredited batch testing with a Certificate of Analysis on request.
  • UK manufacturing & clear labelling — easier to verify and trust.
With mastic, purity and provenance are the whole story.
