Quick Summary

Mastic Gum (Pistacia lentiscus) is a resin obtained from the mastic tree, traditionally valued for its antioxidant, anti-inflammatory, antimicrobial, and potential therapeutic properties. Recent clinical studies have primarily investigated its possible applications in managing knee osteoarthritis and inflammatory bowel disease, among other conditions. The resin contains bioactive components, especially terpenes and triterpenic acids, which have been studied for various pharmacological effects. However, clinical data remain limited and mostly preliminary.

What is it?

Mastic Gum is a natural resin harvested from the Pistacia lentiscus tree, native to the Mediterranean region. It has historically been used in traditional medicine and as a natural chewing gum. The resin contains a range of compounds, including terpenes and triterpenic acids, which contribute to its biological activities.

Traditional Uses

  • Supporting oral health by reducing bacterial growth and inflammation in the mouth.
  • Relief of digestive discomfort and support for gastrointestinal conditions.
  • Reduction of inflammation and pain, especially in joint disorders such as osteoarthritis.
  • Antimicrobial applications, including treatment of infections.

Active Compounds

The main bioactive compounds in Mastic Gum are terpenes and triterpenic acids. These constituents are believed to contribute to its antioxidant, anti-inflammatory, and antimicrobial effects observed in various studies.

Potential Benefits with Evidence Levels

  • Relief of knee osteoarthritis symptoms: A triple-blind randomized clinical trial found that a multi-herbal product containing Pistacia lentiscus gum improved pain, stiffness, and physical function in patients with knee osteoarthritis over 6 weeks. The product was well tolerated with no severe adverse effects reported. (Evidence level: Randomized controlled trial)
  • Antioxidant and anti-inflammatory effects in inflammatory bowel disease (IBD): Mastic Chios supplementation showed significant antioxidant and anti-inflammatory effects in IBD across several randomized controlled trials and animal studies. However, further high-quality clinical trials are needed to confirm efficacy. (Evidence level: Systematic literature review including clinical and preclinical studies)
  • Potential antibacterial and anti-Helicobacter pylori activity: Extracts from Pistacia lentiscus and related plant products exhibited anti-inflammatory and anti-Helicobacter activity in animal and in vitro studies. Clinical trials in humans are required for confirmation. (Evidence level: Preclinical and systematic reviews)
  • Oral health support: Herbal products containing Pistacia lentiscus demonstrated antimicrobial, anti-inflammatory, and antioxidant properties relevant to managing oral health issues such as periodontitis, halitosis, and oral mucosal conditions. Some clinical evidence supports their adjunctive use. (Evidence level: Systematic reviews of clinical and preclinical studies)

Side Effects

Clinical trials involving Mastic Gum supplementation report good tolerability with no significant or serious adverse effects. However, data are limited and rare or long-term side effects have not been well characterized.

Drug Interactions

Currently, there is insufficient clinical evidence regarding drug interactions with Mastic Gum or Pistacia lentiscus preparations. Caution is advised until further pharmacokinetic and clinical studies clarify potential interactions.

Who Should Avoid It

  • Individuals with known allergies to plants in the Anacardiaceae family should exercise caution when using Mastic Gum.
  • Use during pregnancy and breastfeeding is not recommended due to lack of safety data.

Evidence Limitations

The available clinical evidence for Mastic Gum is limited, primarily involving small-scale randomized controlled trials and systematic reviews that include animal and in vitro studies. Most clinical research involves herbal combinations containing Pistacia lentiscus, complicating the isolation of its specific effects. Larger, rigorously designed, placebo-controlled clinical trials with extended follow-up are needed. Furthermore, safety data, standardized dosage recommendations, pharmacokinetic profiles, and information on drug interactions and special populations remain underexplored.
