Is mastic gum safe?

Mastic gum has been chewed and used as a food for thousands of years and is generally well tolerated. As with any food supplement, a few sensible precautions apply:

  1. Mastic gum is generally considered safe. If you experience any unusual or persistent effects, stop using it and contact your doctor.
  2. Pregnancy and breastfeeding: there isn’t enough reliable information, so it’s best to avoid use during these times.

  4. Allergy: people allergic to mastic trees or other Pistacia species (such as pistachio) may also react to mastic. See our allergen statement for details.

  6. Do not exceed the recommended daily dose, keep out of the reach of children, and remember a supplement does not replace a varied, balanced diet.
Important: Mastic gum is a food supplement, not a medicine. It is not intended to diagnose, treat or replace medical care. If you have a health condition or take medication, talk to your doctor before use.
