Yarrow for Oral Care

In a recent article I described the use of the herb yarrow (Achillea millefolium) as first aid for a bleeding wound. In this article, I’ll share how I came to swear by it for oral health care.

This story begins with me losing two teeth in about 2009 and 2010. At the urging of a (probably well-meaning) dentist, I had them both replaced with implants.

After that experience, I started exploring natural oral care. I stopped using toothpaste when I learned that almost everything we expect of modern toothpastes is achieved using ingredients that are harmful to our teeth, our gums, and/or our oral biome.

I replaced toothpaste with very simple tooth-brushing ingredients, which I felt worked much better than toothpastes to keep my mouth healthy.

(I also learned a lot about the nutritional principles that could have enabled me to keep my teeth, but that’s a whole other story.)

My toothpaste boycott was interrupted by the birth of our second child and a big move from the US back to my home country of Australia, both of which happened in 2011.

And for the next few years, with young children keeping me busy and distracted, I went back to the convenience of toothpastes in tubes labelled “natural” from the nearest health food store.

Then in 2017, the gum tissue around the first of my two tooth implants started receding, apparently unstoppably.

At the time, I had kind of forgotten what I previously learned about toothpastes and natural oral care. It didn’t occur to me to look at what I was putting on my toothbrush every day that might be affecting my gum health. I just went along to a dentist and asked his advice.

The dentist said that he didn’t see how the gum tissue could be returned to health, and that if the recession continued the jaw bone would begin to disintegrate too. The best thing would be to have the implant removed.

So that’s what I did, at considerable cost and with considerable discomfort.


Yarrow To The Rescue

After having the first implant painfully removed, I felt motivated to take up my oral health care crusade again.

I stopped using toothpastes for the second time (it was much harder this time because now I had children who were accustomed to the sweet, smooth stuff in the tubes), and was again using simple ingredients to brush with. (I’ll describe those ingredients in an upcoming online Workshop.)

Toothpastes, even the “natural” ones, contain a lot of ingredients that are counterproductive to gum health and general oral well-being, and I think that eliminating them was a step in the right direction.

But apparently it wasn’t enough, because then the gum tissue around the second implant began to deteriorate in the same way the first one had.

My first reaction was, “Oh no, I’m going to have to have this one painfully and expensively gouged out, like I had to with the first one.”

But then I remembered something else that might help: yarrow tincture[i].

When I started adding yarrow tincture to my rinsing water after brushing, as if by magic, the tender, painful area around the base of the implant stopped being tender and painful. The gum tissue stopped receding. The issue just went away, and now, almost three years later, it hasn’t come back.

(In case you’re unfamiliar with what a herbal tincture is I’ll explain in a minute, but first I want to share a bit about yarrow.)


About Yarrow

Yarrow has an extraordinary range of medicinal uses.

Most of the literature I’ve found on using yarrow medicinally describes its uses in reducing fevers, treating colds and flus, for digestive support, for wound first aide and ongoing care, for cardiovascular support and circulatory health, urinary support, post-partum and menstrual support, and skin conditions.

Pretty impressive, right? But that list is only a beginning – if you really go searching for more, you’ll find that the list of yarrow’s possible uses can get really, really long. And somewhere in the bottom third or so of the longest lists there are references to its use for toothaches and periodontal (gum) disease.

Yarrow is anti-inflammatory, antiseptic/anti-microbial, and astringent (causes tightening of body tissues). It is both styptic (stops bleeding), and also has the ability to support healthy blood circulation. All of these make it extremely helpful in preventing and healing gum disease.

Yarrow is easy to find and grow almost anywhere in the world, and making a tincture from it at home is super easy[ii].


About Herbal Tinctures

Yarrow Tincture
Image by Author

Tinctures are herbal preparations that use a solvent (usually alcohol, but sometimes vinegar or glycerin) to extract medicinal properties from a plant and preserve them in liquid form. Alcohol extracts a wide range of plant constituents and allows for easy absorption of healing compounds into the bloodstream when the medicine is taken internally.

Tinctures that use the aerial (above ground) parts of the plant, yarrow included, are more potent if made from fresh herbs rather than dried.

Tinctures can be used externally as well as internally. Yarrow tincture for example can be sprayed on the skin to repel insects[iii]; sprayed on a wound to stop bleeding[iv], protect against infection, and promote healing; or added to the water when we rinse our mouths to protect against unfriendly bacteria, support healthy circulation, and tighten and tone the gum tissue.


Yarrow Cautions

  • avoid the use of yarrow during pregnancy
  • be aware that yarrow can interfere with blood pressure medications
  • long term topical use of yarrow can occasionally cause the skin to become photosensitive
  • yarrow may cause an allergic reaction in people who are sensitive to plants in the Asteraceae/Compositae family, which includes ragweed, chrysanthemums, marigolds, daisies, and others – if in doubt, check with a herbalist or naturopath before using yarrow.


Some Resources

In this article, Susun Weed describes yarrow as an easy-to-find-or-grow antibacterial and astringent herb with a long history of use in oral health. In this one, she says she has sprayed yarrow tincture into her throat to short-circuit a sore throat, and has used it on a tooth that throbbed for instant pain relief.

This article by lists yarrow for toothache, and this one from says it’s helpful in promoting healing of mouth sores due to braces, surgery and overzealous teeth cleaning.

This article by shares that yarrow tea swished around in your mouth will have an antimicrobial action, stop bleeding, and prevent infection.

Finally, I always like it when science finally arrives at agreement with older healing modalities. This study concluded that yarrow was more helpful in healing the debilitating side-effect of chemotherapy on gum health than the conventional treatment.

[i] Yarrow tea, made with fresh yarrow from the garden, would probably work nearly as well as tincture for a mouth rinse. I tend to use the tincture because I can keep it in the bathroom cabinet rather than having to remember to have yarrow tea brewed for teeth cleaning.

[ii] It’s very easy to make herbal tinctures at home, but because I don’t yet have enough yarrow growing at our place, currently I’m buying my yarrow tincture online. I choose herbalists who make their own preparations. I avoid buying from large companies that manufacture in large volumes and promote the idea that herbal medicine should be left to white-coated technicians in shiny labs with expensive equipment.

[iii] Yarrow should not be used on the skin over long periods of time as it can cause sun sensitivity.

[iv] You can probably dilute in water if you’re spraying a child who might protest about the sting from the alcohol in the tincture, but spray it neat if you’re in a hurry. You can apologise later if it stings.

  1. I had sores from accidentally biting my cheeks on the inside of my mouth.

    They were around for a few days when I remembered I had yarrow tea on hand. One side healed up that same day. The other took a day more to heal. However much of the pain and irritation was gone shortly after drinking the tea. Yarrow really is wonderful.

    I’ve had acid reflux for the better part of a year, I hope that regularly drinking the tea will help heal whatever damage has been done to my throat. Fingers crossed. Go Yarrow !

    1. Hi Patrick, I’m glad (and not surprised) that yarrow helped your mouth sores. I personally wouldn’t hope for yarrow to help with acid reflux (try dandelion tincture) and I would think it might be too astringent to help an irritated/inflamed throat (consider slippery elm powder mixed with honey — or perhaps you or someone else knows of a more local alternative than slippery elm powder). Good luck, and thanks for commenting.

  2. Thank you for this valuable information. Such a thorough article, well written. Much to think about (toothpaste alternative ) as at 61 my gums are receding a bit. I am off to try it as my tooth /gum pain is terrible.

    1. Hi Jenny, thanks for commenting. I so hope yarrow will help your gums… I’d be surprised if it didn’t… Good luck!

  3. How long should I use Yarrow tincture for advanced periodontitis and possible pus at bottom of molar? Should I dilute it?

    1. Hi Christine,

      Yes, you should definitely dilute yarrow tincture in water before putting it in your mouth. In this article I’ve suggested adding it to your rinsing water.

      I’m not a dentist or a herbalist; I’ve written here about yarrow from a layman’s point of view and you should do your own research and seek advice from qualified people you trust, whether that’s a dentist or some other health professional.

      From what you describe, I think if I were in your shoes and I didn’t see an improvement within a few days to a week of using yarrow, I’d be off to the dentist. What I’ve written about here is for prevention, not cure, of something as serious as you describe.

      I hope that’s helpful, and good luck.
