# Mastagi (Pistacia lentiscus) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/mastagi **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 4 / 10 **Category:** Middle Eastern **Also Known As:** Pistacia lentiscus, Mastic, Greek Mastic, Chios Mastic, Mediterranean Mastic, Lentisk, Mastic Gum ## Overview Mastagi (Pistacia lentiscus) contains triterpenic acids including masticadienonic acid that exhibit [antimicrobial](/ingredients/condition/immune-support) properties through bacterial cell wall disruption. This Mediterranean shrub has been traditionally used in Unani medicine for gastrointestinal support and digestive disorders. ## Health Benefits • [Antimicrobial](/ingredients/condition/immune-support) activity: In vitro studies show triterpenic acids like masticadienonic acid demonstrate antibacterial effects (MBC 0.202 mg/ml) - evidence quality: preliminary • Gastrointestinal support: Traditional use documented in Mediterranean medicine for digestive issues - evidence quality: traditional only • Oral health benefits: Historical applications in dental care - evidence quality: traditional only • [Antioxidant](/ingredients/condition/antioxidant) potential: Contains polyphenols including gallic acid, catechins, and quercetin glycosides (leaves showing 238.3 mg GAE/g total phenols) - evidence quality: preliminary • [Anti-inflammatory](/ingredients/condition/inflammation) properties: Traditional use suggests benefits, though human clinical evidence not documented - evidence quality: traditional only ## Mechanism of Action Masticadienonic acid and other triterpenic acids in mastagi disrupt bacterial cell membranes and inhibit microbial growth with minimum bactericidal concentrations of 0.202 mg/ml. These compounds interfere with bacterial lipid synthesis and membrane integrity. The [antimicrobial](/ingredients/condition/immune-support) action appears to target gram-positive bacteria more effectively than gram-negative species. ## Clinical Summary Current research on mastagi is limited to preliminary in vitro studies demonstrating [antimicrobial](/ingredients/condition/immune-support) activity of isolated triterpenic compounds. No human clinical trials have been conducted to validate traditional [digestive health](/ingredients/condition/gut-health) claims. The minimum bactericidal concentration has been established only in laboratory settings without human safety or efficacy data. Traditional use evidence comes from historical Mediterranean and Unani medicine practices but lacks standardized clinical validation. ## Nutritional Profile Mastagi (Pistacia lentiscus resin) is a non-nutritive resin consumed in very small quantities (typically 1-5g), making macronutrient contribution negligible. Key bioactive compounds include: triterpenic acids - masticadienonic acid (~17% of resin composition), isomasticadienonic acid (~12%), oleanolic acid (~3%), and tirucallol; polymer fraction - poly-β-myrcene (high molecular weight insoluble polymer comprising ~50% of total resin, indigestible); essential oil fraction (~1-2.5% of resin) containing α-pinene (~65-75% of volatile fraction), β-myrcene (~15%), linalool, and limonene; phenolic compounds including quercetin derivatives and gallic acid at trace levels (<0.5% dry weight); resin acids including masticin and isomasticinic acid. Mineral content is negligible due to small serving size. No significant vitamins, dietary fiber (polymer is insoluble but not classified as dietary fiber), or conventional protein content. Bioavailability notes: the insoluble polymer fraction passes through the GI tract largely intact; triterpenic acids show moderate lipophilicity suggesting absorption via passive diffusion, though clinical pharmacokinetic data in humans remains limited; essential oil components are volatile and partially absorbed via mucosa during mastication. ## Dosage & Preparation No clinically studied dosage ranges are available in the research for mastic resin in any form (extract, powder, or standardized products). The absence of human dosing information or standardization specifics in the literature makes evidence-based dosing recommendations impossible. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for mastagi supplements is extremely limited due to lack of human studies. Potential allergic reactions may occur in individuals sensitive to Pistacia species or related plants in the Anacardiaceae family. No drug interactions have been formally documented, but theoretical concerns exist with [antimicrobial](/ingredients/condition/immune-support) medications due to mastagi's antibacterial properties. Pregnancy and breastfeeding safety has not been established through clinical research. ## Scientific Research The research dossier reveals a significant gap in clinical evidence: no specific human clinical trials, RCTs, or meta-analyses for Pistacia lentiscus resin were found, with no PubMed PMIDs available for such studies. Available research focuses primarily on chemical composition analysis dating back to 1930 and in vitro antibacterial activity rather than human trials. ## Historical & Cultural Context Mastic resin from Pistacia lentiscus has been used historically in Mediterranean traditional medicine, particularly in Greek and Ottoman systems, for gastrointestinal issues, oral health, and as an [antimicrobial](/ingredients/condition/immune-support). Its documented uses predate 1930 chemical research, with applications extending to food and personal care due to its diverse compound profile. ## Synergistic Combinations Licorice root, Slippery elm, [Probiotic](/ingredients/condition/gut-health)s, Chamomile, Peppermint oil ## Frequently Asked Questions ### What is the active compound in mastagi? The primary bioactive compound is masticadienonic acid, a triterpenic acid that demonstrates antimicrobial effects with a minimum bactericidal concentration of 0.202 mg/ml in laboratory studies. ### How does mastagi help with digestion? Mastagi's digestive benefits are based on traditional Unani medicine use for gastrointestinal issues. The antimicrobial triterpenic acids may support gut health by inhibiting harmful bacteria, though human clinical studies are needed. ### Is mastagi the same as mastic gum? Yes, mastagi refers to the resin from Pistacia lentiscus, which is the same source as mastic gum. Both terms describe products derived from this Mediterranean shrub species. ### What dosage of mastagi is recommended? No standardized dosage has been established due to lack of clinical trials. Traditional preparations vary widely, and safety profiles have not been determined through human studies. ### Can mastagi interact with antibiotics? While no documented interactions exist, theoretical concerns arise due to mastagi's antimicrobial properties potentially interfering with antibiotic effectiveness. Consultation with healthcare providers is recommended before combining with antimicrobial medications. ### What is the difference between mastagi resin and mastagi extract forms? Mastagi resin is the pure gum collected directly from Pistacia lentiscus trees, while mastagi extract is a concentrated form that isolates specific compounds like triterpenic acids. The resin form is traditionally used for oral health and has historical precedent, whereas extracts may offer more standardized active compound levels for gastrointestinal support. Your choice depends on whether you prefer whole-resin traditional use or concentrated bioactive compounds. ### Is mastagi safe for children and elderly individuals? Mastagi has a long historical use in Mediterranean cultures with few documented safety concerns for general populations, though pediatric and geriatric safety data from clinical trials remains limited. Elderly individuals with swallowing difficulties should avoid hard mastagi resin due to choking risk, while children under 5 should not use it for the same reason. Consult a healthcare provider before giving mastagi to pregnant women, nursing mothers, or individuals with chronic medical conditions. ### What does current research show about mastagi's effectiveness compared to conventional oral health products? Mastagi contains triterpenic acids with preliminary in vitro antibacterial activity (MBC 0.202 mg/ml), but direct clinical comparisons against conventional antimicrobial mouthwashes or toothpastes have not been published in peer-reviewed literature. Traditional Mediterranean dental applications are well-documented historically, but modern clinical trial data supporting these uses remains limited. More rigorous human studies are needed to establish mastagi's effectiveness relative to evidence-based conventional oral care products. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
