Résine de mastic (Pistacia lentiscus): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does mastic resin work to kill H. pylori bacteria?

Mastic resin contains active compounds including alpha-pinene, verbenone, and unique mastic polymers that demonstrate antibacterial activity against Helicobacter pylori. Research suggests these terpenoids disrupt bacterial cell membranes and may inhibit H. pylori adhesion to gastric mucosa. Additionally, mastic appears to reduce gastric acid secretion and provide cytoprotective effects on the stomach lining. Clinical evidence (Level C) indicates mastic can reduce H. pylori colonization, though it works through multiple mechanisms rather than acting as a simple antibiotic. The triterpenoids also contribute anti-inflammatory effects that support mucosal healing.

Does mastic gum interact with any medications?

Currently, there are no well-documented significant drug interactions with mastic resin. As a natural resin that primarily acts locally in the gastrointestinal tract, systemic absorption appears minimal, reducing interaction risk. However, because mastic may affect gastric acid levels and has mild antiplatelet properties due to its terpenoid content, patients taking anticoagulants or acid-suppressing medications should consult a healthcare provider. Always inform your physician about all supplements when taking prescription medications, as individual responses may vary.

What is the recommended daily dosage for mastic gum?

The standard adult dosage for mastic resin is 1 gram of whole mastic gum daily, typically divided into two doses, or 350mg of standardized extract taken three times daily. For H. pylori eradication protocols, treatment typically continues for 2-4 weeks. The resin can be chewed directly as gum or taken in capsule form. For oral hygiene purposes, mastic is available in chewing gum formulations used 2-3 times daily. Always follow product-specific instructions, as concentration varies between preparations.

Is mastic resin safe to use during pregnancy and breastfeeding?

Mastic resin is generally considered safe during pregnancy and breastfeeding when used at recommended doses. It has a long history of traditional use dating back to ancient Greek medicine without documented adverse effects in pregnant women. The resin has minimal systemic absorption, which further reduces concern. However, pregnant women should consult their healthcare provider before starting any new supplement. No specific pregnancy warnings exist, but as with all herbal remedies during pregnancy, use the lowest effective dose for the shortest necessary duration.

What are the main health benefits of mastic resin?

Mastic resin from Chios, Greece, is primarily used for digestive complaints, including peptic ulcers, gastritis, and H. pylori infection. Clinical evidence (Level C) supports its ability to reduce H. pylori bacteria and promote ulcer healing. Additional benefits include oral hygiene support—mastic chewing gum reduces oral bacteria and improves gum health. Traditional uses extend to managing dyspepsia and intestinal discomfort. The resin's anti-inflammatory and antimicrobial triterpenoids contribute to these effects. Mastic has been used safely since ancient Greek times for gastrointestinal and oral health applications.

Résumé

Mastic resin (Pistacia lentiscus) is a natural aromatic resin from the Mediterranean region known for its anti-inflammatory, antioxidant, and antimicrobial properties [PMID:35276949, PMID:38892571].

Contexte

Mastic resin is obtained from the trunk and branches of the Pistacia lentiscus tree, an evergreen shrub of the Anacardiaceae family primarily found in the Mediterranean region [PMID:35276949, PMID:38892571]. Chios mastic gum (CMG) is a specific variety (var. Chia) produced exclusively in the southern part of Chios, Greece [PMID:35276949, PMID:32092498].

Usages traditionnels

Since antiquity, it has been used in traditional Greek medicine for treating gastrointestinal disorders, such as gastralgia and peptic ulcers, and as a cosmetic agent [PMID:32092498, PMID:22414110].

Composés actifs

Bioactive constituents include flavonoids, phenolics, triterpenoids (specifically 24Z-masticadienonic acid and 24Z-isomasticadienonic acid), and volatile compounds such as α-pinene and β-myrcene [PMID:38892571, PMID:22044444, PMID:39766325, PMID:33307832].

Mécanisme d'action

The resin exerts its effects primarily through anti-inflammatory and anti-oxidative properties [PMID:35276949]. It has been shown to inhibit the production of pro-inflammatory substances by activated macrophages and modulate intracellular signaling pathways related to apoptosis and cell proliferation [PMID:22949590, PMID:37147480].

Preuves cliniques

Preuve CDyspeptic disorders and skin inflammations

The European Medicines Agency has given approval for the use of mastiha for mild dyspeptic disorders and skin inflammations [PMID:35276949].

Preuve BHypercholesterolemia and Glucose levels

In a randomized placebo-controlled pilot study of healthy volunteers with total cholesterol >200 mg/dl, a daily dose of 1g of crude CMG reduced total cholesterol by 11% after eight weeks [PMID:26311707].

Preuve AInflammatory Bowel Disease (IBD)

A systematic review of RCTs and preclinical studies investigated the effects of Mastic Chios supplementation in IBD [PMID:37001176].

Preuve COral Health

Mastic gum displays antibacterial properties, inhibits plaque accumulation, and provides effective antibacterial activity against periodontal bacteria [PMID:37147480].

Preuve DGastric Ulcers / H. pylori

Research indicates in vivo and in vitro activity against Helicobacter pylori, the main cause of gastric ulcers [PMID:22414110, PMID:35417884].

Sécurité et effets indésirables

Sub-acute toxicity studies in rats at a dose of 0.2857g/kg for 14 days showed no significant histopathological changes in the heart, liver, kidney, or spleen [PMID:37580926]. However, gum mastic has been identified as a cause of contact dermatitis in allergic patients, with 72% of Mastisol-allergic patients testing positive for gum mastic [PMID:33273244].

Synthèse des preuves

The evidence consists primarily of narrative and systematic reviews (Level A and C) and some pilot RCTs (Level B) and in vitro/animal studies (Level D), suggesting broad therapeutic potential but requiring more large-scale clinical trials for definitive conclusions.
