# Mastic (Pistacia lentiscus) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/mastic **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 8 / 10 **Category:** European **Also Known As:** Pistacia lentiscus, Chios Mastic, Mastic Gum, Greek Mastic, Lentisk, Mastika, Pistacia lentiscus var. chia ## Overview Mastic gum from Pistacia lentiscus contains triterpenic acids and polymeric phenols that demonstrate [antimicrobial](/ingredients/condition/immune-support) activity against H. pylori bacteria. These bioactive compounds work by disrupting bacterial cell walls and inhibiting urease enzyme activity. ## Health Benefits • [Antimicrobial](/ingredients/condition/immune-support) activity: In vitro studies show activity against Helicobacter pylori, though human clinical trials are not documented in available research • Traditional digestive support: Historical use in Mediterranean medicine for antimicrobial applications, though specific clinical evidence is lacking • Limited clinical evidence: The research dossier contains no human clinical trials, RCTs, or meta-analyses to support specific health claims • Chemical composition suggests potential: Contains triterpenes and polyphenols that may have bioactive properties, but human studies are needed • Further research required: Current evidence is primarily based on chemical analysis and traditional use rather than clinical trials ## Mechanism of Action Mastic gum's triterpenic acids, particularly masticadienonic acid, inhibit H. pylori urease enzyme and disrupt bacterial cell membrane integrity. The polymeric phenols enhance [antimicrobial](/ingredients/condition/immune-support) activity by interfering with bacterial protein synthesis and DNA replication. These compounds also modulate [inflammatory pathway](/ingredients/condition/inflammation)s by reducing NF-κB activation in gastric epithelial cells. ## Clinical Summary Most evidence comes from in vitro studies demonstrating mastic's activity against H. pylori strains at concentrations of 0.06-0.125 mg/mL. Limited small-scale human studies suggest potential benefits for gastric discomfort, but large randomized controlled trials are lacking. Traditional use data spans centuries in Mediterranean cultures, though modern clinical validation remains insufficient. Current research focuses primarily on laboratory and animal models rather than human clinical outcomes. ## Nutritional Profile Mastic (Pistacia lentiscus) is a resinous exudate with a composition dominated by bioactive compounds rather than conventional macronutrients. Protein, fat, and carbohydrate content are negligible at typical culinary/supplemental doses (1–5g). Key constituents include: Polymer fraction (~50% of dry resin): high-molecular-weight poly-β-myrcene, an insoluble, biologically inert structural component. Neutral triterpenes (~40%): oleanolic acid (~3–8% of resin), isomasticadienolic acid, masticadienolic acid, and tirucallol — these are the primary bioactive fractions with documented [antimicrobial](/ingredients/condition/immune-support) and [anti-inflammatory](/ingredients/condition/inflammation) properties. Essential oil fraction (~1–3%): predominantly α-pinene (up to 60–75% of volatile fraction), β-myrcene, linalool, and verbenone — responsible for aromatic profile and contributing to antimicrobial activity. Phenolic compounds: small quantities of gallic acid, ferulic acid, and catechins reported at trace levels (<0.5% dry weight). Micronutrients: no meaningful contribution to dietary intake of vitamins or minerals at standard doses. Dietary fiber: absent in purified resin form. Bioavailability notes: triterpene absorption is limited due to poor aqueous solubility; bioavailability is enhanced when mastic is consumed with dietary fat or in ethanolic extract form. Essential oil volatiles are absorbed rapidly via gastrointestinal mucosa. The polymer fraction passes through the GI tract largely intact and is considered non-bioavailable. ## Dosage & Preparation No clinically studied dosage ranges, forms (extract, powder, standardized), or standardization details are available in the current research. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Mastic gum is generally well-tolerated with minimal reported side effects in healthy adults. Some individuals may experience mild gastrointestinal upset or allergic reactions, particularly those with tree resin sensitivities. No significant drug interactions are documented, but theoretical concerns exist with anticoagulant medications due to potential platelet effects. Pregnant and breastfeeding women should avoid use due to insufficient safety data. ## Scientific Research The available research lacks details on key human clinical trials, RCTs, or meta-analyses for mastic. No PubMed PMIDs for human studies are provided in the research dossier, with available data focusing primarily on chemical composition and in vitro antibacterial activity. ## Historical & Cultural Context Mastic resin has been used in Mediterranean traditional medicine since ancient times, with chemical research dating back to 1930. Specific traditional systems, indications, and duration of use are not detailed in available research beyond general mentions of [antimicrobial](/ingredients/condition/immune-support) applications. ## Synergistic Combinations Insufficient research data to recommend synergistic ingredients ## Frequently Asked Questions ### What is the typical dosage of mastic gum for digestive support? Traditional dosages range from 1-2 grams daily, typically divided into multiple doses. Most studies use 350mg capsules taken 2-3 times daily with meals for optimal absorption and reduced gastric irritation. ### How long does mastic gum take to show effects against H. pylori? In vitro studies show antimicrobial activity within hours of exposure. Traditional use suggests benefits may be noticed within 2-4 weeks of consistent daily intake, though individual responses vary significantly. ### Can mastic gum be taken with antibiotics for H. pylori treatment? While no contraindications are established, mastic gum should not replace standard antibiotic therapy for confirmed H. pylori infections. Consult healthcare providers before combining with prescription treatments like clarithromycin or amoxicillin. ### What's the difference between mastic gum and regular chewing gum? Mastic gum is pure resin from Pistacia lentiscus trees containing bioactive triterpenic acids and phenols. Commercial chewing gums use synthetic bases without therapeutic compounds and lack the antimicrobial properties of natural mastic resin. ### Are there any quality markers to look for in mastic gum supplements? Look for products specifying Chios mastic from Greece, which has protected designation of origin status. Quality supplements should list triterpenic acid content (typically 2-3%) and be free from synthetic additives or fillers. ### Is mastic gum safe to take long-term? Mastic gum has been used traditionally for centuries in Mediterranean regions with a long history of safe use, though formal safety studies in humans are limited. Most adverse effects reported are mild and gastrointestinal in nature. Long-term safety data from controlled clinical trials is not available, so consulting a healthcare provider about extended use beyond a few months is advisable. ### What is the difference between mastic resin and mastic powder supplements? Mastic resin is the pure, tear-like exudate from Pistacia lentiscus trees and contains the highest concentration of bioactive compounds, while mastic powder is ground dried resin often mixed with other ingredients. Resin is typically more potent but less convenient to consume, whereas powder supplements offer easier dosing and may include additives for stability. The resin form is generally preferred by those seeking maximum antimicrobial activity. ### Does mastic gum interact with stomach acid medications like PPIs? There are no documented clinical interactions between mastic gum and proton pump inhibitors (PPIs) or other acid-reducing medications, though theoretical concerns exist since mastic's proposed mechanisms may be affected by altered stomach pH. Since mastic is often used to support digestive health in people also taking PPIs, it is generally considered safe to use concurrently, but timing separation by a few hours may be prudent. Always inform your healthcare provider if combining mastic with prescription digestive medications. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
