What the European Medicines Agency Says About Mastic Gum

When we tell you mastic gum has a 2,500-year traditional-use record and a modern peer-reviewed scientific record, we mean the European Medicines Agency wrote a formal Assessment Report on it. Here’s what that report actually says, why it matters, and where you can read it yourself.

The report, in one sentence

In 2015, the European Medicines Agency’s Committee on Herbal Medicinal Products published a formal Assessment Report titled “Assessment report on Pistacia lentiscus L., resina (mastic)” — an evidence review compiling traditional-use documentation, pharmacological studies, clinical trial data, and safety records on mastic gum.

You can read the full report on the European Medicines Agency’s website. We’re not going to reproduce it here in full — it’s long and dense — but we’ll walk through what it documents and what that means for how we talk about the ingredient on the OmniVita line.

What the report documents

1. Traditional use

The EMA report compiles centuries of documented use of mastic gum in traditional Mediterranean medicine. The historical record covers Roman medical writings, Byzantine medical texts, Ottoman medicine, and traditional Greek herbal practice. The primary documented use across all these traditions: digestive support — what we’d now call gut comfort, upper-GI function, and oral health.

This is not folk-wisdom hearsay. The EMA report cites primary historical sources, dated literature, and the continuous cultivation record on the island of Chios, which has produced mastic gum from Pistacia lentiscus trees for over 2,500 years under controlled cultivation.

2. Modern pharmacological research

The report compiles published research on mastic gum’s components — including the resin’s natural compounds and their documented effects on gut microbial environment, gastric mucosa function, and other physiological systems. Studies cited in the report cover both in-vitro work (cellular and microbial studies in lab conditions) and in-vivo work (clinical trials in human subjects).

One area the report covers in detail: mastic gum’s bactericidal effect on certain gastric bacteria, including studies on Helicobacter pylori. Studies cited in the assessment include work by Marone et al. (2001), Bona et al. (2001), and Kottakis et al. (2009), which examined mastic gum’s antibacterial properties at various concentrations.

We’re going to be careful with how we frame this. Our product is a dietary supplement, not a drug. We are not claiming that Intact Digest™ or Intact Endurance™ treats H. pylori infection or any other infection. We are pointing to the published scientific literature on the ingredient itself, as a matter of educational transparency — not as a treatment claim about our product.

3. Safety record

The EMA report includes safety data from both traditional-use records and modern clinical trials. The safety profile documented across this evidence base is favorable at standard dietary supplementation levels. Adverse-event reports in the literature are uncommon at typical use doses.

This is part of why we feel confident putting mastic gum on the back label of every Intact-line product, fully disclosed, at documented dosing levels. The safety profile of the ingredient is well-characterized.

What the report does NOT say

This matters as much as what the report does say. The EMA Assessment Report on mastic gum:

• Does NOT approve mastic gum as a treatment for any specific disease.
• Does NOT claim that mastic gum cures or prevents H. pylori infection, cardiovascular disease, or any other condition.
• Does NOT establish mastic gum as a substitute for medical treatment of any condition.
• Documents traditional use and pharmacological research as evidence for further study — not as established therapeutic claims.

This is why our customer-facing language is structure/function-only: we say what the ingredient supports in the normal function of the body, not what it treats. That’s the FDA DSHEA framework and it matches the level of evidence the EMA report itself documents.

Additional peer-reviewed sources we reference

The EMA report isn’t the only published research on mastic gum. We also reference:

• Blomquist, S.A., et al. (2024). “Mastic Gum: A Promising Phytotherapeutic for Cardiometabolic Health.” Nutrients, 16, 2941. A 2024 peer-reviewed review article on emerging research into mastic gum’s components and their study in relation to cardiometabolic markers.
• Marone et al. (2001), Bona et al. (2001), Kottakis et al. (2009) — foundational studies on mastic gum’s antibacterial properties, cited in the EMA Assessment Report.
• Ahlawat et al. (2020). “Gut–organ axis: A microbial outreach and networking,” Letters in Applied Microbiology, 72(6). Published research on the gut’s relationship to other organ systems through microbiota signaling pathways — relevant background for understanding why gut-health-as-foundation is part of the OmniVita worldview.
• Marchesi et al. “The gut microbiota and host health: a new clinical frontier.” A foundational review article in the field of gut-microbiome research.

All of these are publicly available through peer-reviewed publication archives.

Why we’re telling you this

Because most supplement brands say “backed by science” without ever pointing you to the science. We think that’s lazy. We’d rather say “here are the specific sources we’re drawing from, here’s what they say, here’s what they don’t say, and here’s how that maps to what we put on the label.”

The structure/function language on every OmniVita PDP — supports normal gut microbial balance, supports normal sleep quality, supports the body’s normal recovery from exercise-induced muscle soreness — is anchored to this evidence base. We don’t overclaim past it. We don’t hide behind “proprietary research.” The sources are public. The structure/function framework is FDA DSHEA-compliant. The disclaimers are everywhere they should be.
