Mastic Gum - Properties and Storage

In short: Mastic gum (masticha, mastix, mastiha) is the natural resin of Pistacia lentiscus. This guide covers how to use and dose it, how to chew raw tears, how to grind it into powder, and how to store it properly. As a food supplement, mastic contributes to the normal function of the digestive system.

Properties of mastic gum

Mastic gum is a natural plant resin, so its physical properties change with temperature and storage:

1. It reacts to temperature — softer when warm, harder when cold.
2. Piece size affects texture — larger pieces are usually softer; smaller pieces dry and harden faster.
3. Different pieces suit different uses — medium or large pieces are better for chewing, while smaller pieces are easier to grind into powder.
4. Colour indicates freshness — whiter resin is usually fresher; yellower pieces are older and may be harder.

Masticlife brand — original Chios mastic

Masticlife products are made from authentic mastic harvested on the Greek island of Chios. The brand works directly with the official producers’ organisation as an authorised partner of the Chios Gum Mastic Growers Association.

Usual dosage & tips

The right amount depends on the product form — raw resin, powder, capsules, sachets or chewing gum. Always follow the dosage instructions on the packaging. See our guide to the correct dosage of mastic gum.

• Take capsules or powder on an empty stomach, usually about 30 minutes before meals.
• Swallow capsules with enough water. Masticlife uses HPMC vegan capsules — and there’s a guide if you find capsules hard to swallow.
• Mastic is a natural resin and does not dissolve in water.
• If mastic powder sticks together in the heat, it usually keeps its taste and properties.
• If you are unsure whether mastic is suitable for you, consult your doctor.

How to chew raw mastic gum

1. Take a small piece of raw mastic resin (a “tear”).
2. Place it in your mouth and start chewing slowly.
3. At first it may feel hard or crumbly.
4. After a short time it softens and becomes elastic, like chewing gum.
5. Keep chewing for several minutes.

Raw resin pieces — mastic tears — are natural crystals that vary in size, shape and hardness.

How to store mastic gum

1. Store powder, capsules and sachets in a cool place, ideally below 18 °C.
2. A refrigerator is suitable for long-term storage.
3. In higher temperatures, natural mastic powder may stick together into lumps.
4. If that happens, gently tap the container to break it apart again.
5. You can also crush resin into powder yourself — see how to crush mastic gum powder.
