Myrrh has been used in oral care for over 4,000 years. Here's why it still belongs in your toothpaste.

If you've ever read through the ingredient list on a genuinely natural toothpaste, you've likely seen myrrh listed somewhere near the bottom — tucked behind the hydroxyapatite and the essential oils. Most people skip past it. That's a mistake.

Myrrh toothpaste is one of the oldest forms of intentional oral care in human history, and modern botanical research increasingly reflects what traditional practitioners have known for centuries. In this post, we're breaking down what myrrh actually does in a toothpaste formula, why CO₂ extraction makes a meaningful difference, and what to look for if you want a toothpaste that earns its herbal claims.

Myrrh isn't just a traditional ingredient — it's one of the most researched botanicals in oral care, with centuries of traditional use and a growing body of scientific interest behind it.

What Is Myrrh?

Myrrh is a resin harvested from Commiphora trees native to the Arabian Peninsula, the Horn of Africa, and parts of South Asia. When the bark is cut, a yellowish sap seeps out and hardens into irregular reddish-brown chunks — the raw resin that has been traded, burned, and used in wellness traditions for millennia.

In ancient Egypt, myrrh was used in embalming preparations and sacred incense. In Ayurvedic medicine, it appears as guggul and is associated with purification and circulation. Across nearly every ancient tradition that had access to it, myrrh found its way into oral care rituals — chewed directly, dissolved in water as a rinse, or worked into tooth cleaning preparations.

Modern chemistry has identified the active constituents behind this long history: a class of compounds called sesquiterpenes and terpenoids (including furanoeudesma-1,3-diene and curzerene), along with polysaccharides and phenolic acids. These compounds are responsible for myrrh's continued presence in botanical research today.

What Myrrh Does in a Toothpaste Formula

1. Gum Comfort

Myrrh has one of the longest documented histories of use in oral care specifically for gum comfort. Traditional herbal preparations — from ancient Egyptian formulas to Ayurvedic tooth powders — consistently featured myrrh for its warming, soothing character on gum tissue. Modern botanical research has examined myrrh-containing oral preparations and noted differences in gum appearance and feel among users of myrrh-based formulas.

For anyone using a natural toothpaste as part of a daily oral care routine, myrrh pairs especially well with aloe vera, licorice root, and rhatany root — a combination that shows up throughout the traditional herbal oral care canon.

2. Daily Freshness

Myrrh contributes a warm, resinous depth to a toothpaste formula that botanical mint alone doesn't provide. In a well-formulated natural toothpaste, myrrh works as part of a freshness system — providing lasting breath support with a character that's noticeably different from the sharp, alcohol-driven "clean" of conventional toothpastes.

It also works gently with the oral environment rather than overwhelming it. Conventional synthetic antiseptics affect the entire mouth broadly. Botanical actives like myrrh have a more selective traditional profile — which is why herbalists have favored them for daily use over centuries.

3. Botanical Soothing

Myrrh's traditional use as a soothing botanical isn't folk medicine nostalgia — the terpenoid compounds in myrrh resin are among the most studied in botanical wellness research. In the oral care context, this translates to a formula that feels genuinely comfortable on sensitive gums rather than harsh or stripping.

If you've ever used a natural herbal toothpaste and noticed your gums felt calmer and less reactive after a few weeks of consistent use, the myrrh in the formula may be part of that story.

4. Breath Freshness Without Alcohol

Myrrh has a warm, slightly bitter, resinous scent — not the sharp mint blast of conventional toothpastes. It contributes lasting breath support without the drying effect of alcohol-based formulas, which can actually worsen breath over time by drying out oral tissue.

CO₂ Extraction: Why It Matters for Myrrh

Not all myrrh extract is created equal. The most common (and cheapest) extraction method uses alcohol or high-heat steam to pull compounds from the resin. Both methods degrade heat-sensitive terpenoids — meaning the extract you get is a diminished version of the original compound profile.

CO₂ extraction uses pressurized carbon dioxide as the solvent. Because CO₂ becomes a liquid at relatively low temperatures and leaves zero residue when it evaporates, CO₂ extracts preserve the full terpenoid profile of the myrrh resin — including the more volatile compounds that give it its distinctive herbal potency.

When a toothpaste lists "Myrrh CO₂" on the ingredient deck, it's a meaningful distinction. It signals that the formulator chose the more expensive, more complete extraction method over the cheaper alternatives. Look for it.

What to Look for in a Myrrh Toothpaste

• CO₂ vs. standard extract: CO₂ matters for compound integrity. Standard alcohol or steam extracts lose volatile terpenoids in processing.
• Position in the ingredient list: Ingredients listed higher appear in greater concentration. Myrrh near the middle or top of a botanical stack indicates meaningful inclusion, not a label ingredient.
• Supporting botanicals: Myrrh works best alongside rhatany root, licorice root, clove, calendula, or colloidal silver — botanicals with complementary traditional oral care histories.
• No synthetic antiseptics: If a formula includes triclosan, chlorhexidine, or cetylpyridinium chloride alongside myrrh, the synthetic ingredient is doing the heavy work and the myrrh is decoration.
• Fluoride-free: Most consumers seeking out myrrh toothpaste are looking for a complete natural formula. If the toothpaste contains fluoride, understand why before buying.

Myrrh in Living Crystal Toothpaste

Our Living Crystal Toothpaste uses Organic Myrrh CO₂ as part of a 30+ botanical complex. It sits alongside rhatany root, licorice root CO₂, organic calendula, usnea lichen, clove, tea tree, and a full essential oil blend including peppermint, spearmint, wintergreen, and cinnamon bark.

The mineral foundation — spherical hydroxyapatite, theobromine, colloidal silver, zinc citrate, xylitol, zeolite clinoptilolite, bentonite clay, kaolin clay — handles the structural and mineral work. The botanical layer, anchored by myrrh, handles the comfort and breath-freshening depth that pure mineral formulas can't replicate on their own.

That combination is why Living Crystal is the closest thing we make to a complete oral care formula in a single tube.

If you want to extend the myrrh benefit to your rinse as well, our Restorative Mouth Rinse also includes Myrrh CO₂ as part of its 22-botanical formula — making the brush + rinse combination a consistent myrrh-forward oral care routine from start to finish.

Most people switch to natural toothpaste for what it doesn't contain. They stay because of what it does. Myrrh is one of the reasons.

The Bottom Line

Myrrh toothpaste isn't a trend or a marketing hook. It's one of the oldest documented uses of a botanical compound in oral care, backed by centuries of traditional practice and growing botanical research interest. When you see Myrrh CO₂ on an ingredient deck, you're looking at a formulator who understood why it belongs there.
