Myrrh is a dried gum resin from the thorny tree Commiphora myrrha. The tree grows in dry parts of Somalia, Ethiopia, Kenya and southern Arabia. Cut bark bleeds a pale sap that hardens into reddish-brown lumps.
People have burned it, chewed it and soaked it in alcohol for thousands of years. Today it is sold as a tincture, a mouth rinse, a toothpaste and capsules.
The honest verdict is that human evidence is thin. The best-known use is a mouth rinse for sore gums. Even that rests on small, weak studies.
Long traditional use is not proof that a remedy works, and it is not proof that it is safe. Both points matter here. Myrrh has real cautions, listed further down this page.
Most of what is known about myrrh comes from the laboratory, not from people.
In test tubes, myrrh extracts slow the growth of some bacteria and fungi. In cell studies they appear to damp down signals linked to swelling and redness. Whether that happens in your mouth or your gut is not established.
In rodents, a compound called furanoeudesma-1,3-diene appears to act on opioid receptors. Those are the same nerve targets morphine uses. That is an animal finding, and no one has shown myrrh works as a pain reliever (analgesic) in people.
The resin is sticky and coats wet surfaces. That coating may be part of why a rinse feels soothing. This is a plausible idea, not a proven mechanism.
Animal work also hints at effects on blood sugar and on the lining of the womb. These same hints drive the warnings below.
Myrrh is sold in several forms, and they are not interchangeable.
- Raw resin lumps, burned as incense or soaked in alcohol. - Tincture, an alcohol extract, usually diluted in water as a rinse or gargle.
- Mouthwash, toothpaste and gum paint, where myrrh is one ingredient among several. - Capsules or loose powder for swallowing. - Essential oil, for scent and for diluted use on skin only.
The mouth and throat forms have the longest record of use. Swallowed capsules have far less behind them.
Never swallow the essential oil. It is highly concentrated and has been linked to poisoning.
Myrrh is one of the oldest traded medicines on record. Egyptian papyri list it for wounds and for embalming. It appears in the Bible as a gift and as a burial spice.
Greek and Roman writers described it for sores, coughs and mouth complaints. Islamic medical texts carried the same uses forward.
In traditional Chinese medicine the resin is called mo yao. It was paired with frankincense for bruises, swelling and pain from injury.
In parts of East Africa and Arabia the resin was chewed or used as a wash for cuts and gum trouble. In the twentieth century an Egyptian myrrh extract was sold as a treatment for parasite infections.
These records show standing, not proof. None of them replace testing in people.
Stop myrrh and see a doctor if: - You get a rash, swollen lips or trouble breathing. Call emergency services for breathing trouble. - You get bad stomach pain, ongoing vomiting or diarrhoea. - You pass less urine than usual, or your urine looks dark or bloody. - Your heart feels fast, slow or uneven. - You feel shaky, sweaty or confused, which can mean low blood sugar. - You are pregnant and took myrrh, or you have any bleeding or cramping.
See a doctor anyway if mouth or throat soreness lasts more than a week, or comes with fever. A sore that does not heal needs checking.
In the European Union, myrrh tincture holds traditional herbal registrations for mild mouth and throat soreness. That status rests on long use, not on trials.
In the United States and United Kingdom it is sold as a supplement or oral-care ingredient, not as an approved medicine.
