Mastic Gum
Best-in-class: Mastic Gum
Tree resin from the Greek island of Chios with a small but real evidence base in upper-GI symptoms.
How Mastic Gum actually works
Chios mastic resin has direct bactericidal activity against Helicobacter pylori, demonstrated in vitro and supported by human trials showing eradication in a proportion of patients. It also appears to have independent anti-inflammatory and mucosal-protective effects in the stomach.
Mastic Gum quick facts
| Suggested dose | 350 mg–1 g daily, typically before meals, for 2–4 weeks. |
| How often | daily |
| Who it's for | Upper-GI discomfort, reflux-type symptoms, gastritis. |
✅ Clinically validated
- Small RCTs show symptom improvement in functional dyspepsia versus placebo.
- Some trials show activity against H. pylori, though eradication rates as monotherapy are poor — it is not a replacement for a proper regimen.
📊 Correlative data
- Harvested on Chios for over two thousand years and used across the eastern Mediterranean for stomach complaints — a traditional application that later turned out to have a plausible target in *H. pylori*.
🧪 Theoretical / extrapolated benefits
- Proposed mucosal protection and antibacterial activity in the stomach specifically.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
One of the few gut botanicals treating a cause rather than coating a symptom, and the H. pylori evidence is real though eradication rates are well below triple therapy. Also improves functional dyspepsia scores. Genuine mastic from Chios is expensive and widely adulterated. Worth trying where standard treatment failed or is not tolerated, rather than instead of it.
Mastic Gum — safety & side effects
- GI upset, and headache in some people.
- Allergy in people sensitive to pistachio or mango (same plant family).
- May have mild antiplatelet activity. Not established as safe in pregnancy or breastfeeding — not because harm is documented, but because these are the two populations systematically excluded from the trials. Absence of data is not reassurance. Generally well tolerated.
