Horsetail Herb Profile

Herb Profile Horsetail Shavegrass Uses and Benefits

Horsetail (also called Shavegrass) is an herb that I always keep in the herb cabinet (which is what I have instead of a medicine cabinet).

What is Horsetail?

According to Mountain Rose Herbs:

“The plant at that time was as tall as a modern palm tree. Horsetail, not to be confused with cat-tail, is possibly the most abundant source of silica in the plant kingdom, so much in fact that the herb can be used for polishing metal. It got the name “scouring rush” from this very application. It has had other uses during the ages including as an ingredient in shampoos, skincare products, and in dietary supplements. The German E commission describes its use for urinary tract problems and as a diuretic.”

This article elaborates:

“It is known for its anti-inflammatory, antibacterial, antimicrobial, antioxidant, coagulant, demulcent, diuretic and astringent activity. Reportedly, it has been used in the treatment of a number of health conditions which include brittle bone, hair, teeth and nails, white spots on nails, gingivitis, tonsillitis, inflammation of the mucous membranes of the mouth, rheumatic disorders, edema, osteoarthritis, diabetes, acne, wounds, itchiness, rashes, burns, frostbite, chilblains, athlete’s foot, cracked and tired feet, drawing out pus from boils and carbuncles, ulcers, fistulas, herpes simplex, dyspepsia (impaired digestion), gastrointestinal conditions, cardiovascular diseases, respiratory tract infections, bronchitis, fever, malaria, bladder problems, urinary tract infection, bed wetting in children, kidney stones (nephrolithiasis), prostate problems, hemorrhoids, muscle cramps, tumors, broken bones, fractures, sprains, nose bleed and other heavy bleeding. Horsetail is also known to strengthen the body’s immune system.”

Horsetail Uses

I often use this herb, especially in external preparations due to its skin/hair supportive high silica content:

  • An herbal hair rinse that supports strong hair and hair growth. I brew a strong herbal tea (1/2 cup horsetail to 1 cup water), steep for an hour, strain and use as a hair rinse in the shower.
  • For boils and blisters– I grind the dried herb with plantain and add enough water to create a paste and then pack on to boils or blisters and cover with gauze to speed healing.
  • Sore Throat-For sore throat, I make a gargle with a strong horsetail infusion (steeping horsetail in boiling water and then cooling) with sea salt and lemon juice and then gargle with this mixture a few times a day while symptoms persist.
  • Bedwetting/Bladder Problems– From this article “Studies have shown that this extract may be beneficial for patients suffering from nocturnal incontinence (bed-wetting), bladder and urinary tract infections and weakened bladder. It may also relieve the persistent urge to urinate with Urinary Tract Infection (UTI). Suggested remedy is to take one capsule of Horsetail extract two to three times daily. It is reported that taking a bath with Horsetail tea for at least 15 minutes two to three times a week may be helpful for UTI and Bladder weakness. For steam bath, steep 10 teaspoons of dried Horsetail into one quart of boiling water for 10-15 minutes and add the strained tea into the bath water.”

Additional Notes

I avoid this herb when pregnant or nursing (so my whole married life) but use it externally for hair or skin if needed. From MRH:

“When taking horsetail powder for its diuretic effect, be sure to drink extra water for maximum benefit. Avoid if there are kidney stones. Don’t take horsetail herb if you take an ACE inhibitor for high blood pressure and you have congestive heart failure, as the combination of the herb and the drug can cause accumulation of excessive potassium. Not recommended while pregnant. Toxicity similar to nicotine poisoning has been seen in children who ingest large amounts.”

  1. This is one of the herbs that is on my mental list to try this year. We have it growing wild in our neighborhood and I have been reading about it several places. Thanks for the information that you shared!

    • What state? I want to know if it grows in Texas.
      Thanks

      • Yes it grows great in Texas, I have an area of yard that is almost full shade and the ground stays wet, not much will grow there, until I found horse tail and planted it there, its taken off and grows well.

  2. Where would you get horsetail extract, as mentioned for bedwetting?

    • I think even Amazon carries it or a local health food store might…

      • It is carried at The Vitamin Shoppe under the name of silica. I had a gastric bypass a few years ago and it has helped my nails and hair.

      • Is it safe for children. I have a 6 year old with brittle teeth.

        • Please check out Alternatives to Dentistry, Doug Simons. He’s a seasoned herbalist in NM who has successfully helped people heal cavities and weak teeth (with horsetail). I am doing his protocol to try to heal internal resorption of my tooth. Good luck! This has worked great for my tooth so far!

          • Has it helped with the tooth resorption?

  3. Yes, I like to use it for what its nickname implies, shaving. I’ll use horsetail tea to make the lye solution for shaving soap. Have yet to try it internally, but I think I will now. Every time I’ve ever gone down to the river to harvest it, I’ve ended up with a bad case of poison ivy. So now I find one ounce packages in the spice section at Walmart of all places.

    • Can you elaborate on the horsetail lye solution? I thought in soap making, lye was traditionally taken from wood ash. Can you use horsetail instead then?

      Thanks

    • Hi, I would like to know what it’s under (name) in the spice section at Wal Mart? Tried to find it today and didn’t have any luck. I’d like to be able to make tea, and a hair rinse…..?? Thanks 🙂

      • Hi. Will I get a reply on here or in my email lol? I know it will take time but I keep checking both 🙂

      • Hi, I found it in the Tea section at Wal-Mart. Its in a box and it contains tea bags. I have not found it as a pill nor liquid.
        Also if you have a Mexican Food Store or a Mexican Section at Wal-Mart, it is called Cola de Caballo in Spanish. Hope this helps.

        • You may have already heard this from someone else but, there is now horsetail in pill form. I got mine at a vitamin shop in Illinois. It cost me about 12$ for raw fresh freeze dried horsetail 50 veg caps 375mg by eclectic.

          • If you know somebody in Europe, family or friends, you could order ‘horsetail’ from Switzerland, it is called ‘Prele’ in French, the laboratory’s name is ‘Dieti Natura’ The 200 capsules bottle costs 8 Euro, and it’s better to buy 3 bottles at a time because the third one come at one euro, so for 17 Euros you get 600 hundred capsules, (about 19 dollars), when you order more than 50 euros I get free shipping to France, but they do not have a program to ship outside of Europe.
            This last few years I also buy my ‘Cat’s Claw’ capsules from them, great product and great prices, before I had to get them from South America, but you can get Cat’s Claw in the States now at good prices too.

      • You can buy it in loose leaf form from Amazon by searching for horsetail loose leaf tea. You may also do a web search on google or yahoo and find other merchants that carries it.

        Hope this helps.

  4. I’m currently taking horsetail in tincture form in an effort to heal some torn cartilage in my hip. *fingers crossed*

    • hello,
      Are you still taking horsetail? How much did it help you, just curious as I have started for about a week and see less inflammation in my fingers. I had 2 full hip replacement and problem with the knees, therefore just wondering how much it helped you. Thanks

    • Hi Kate, could u plz tell me what tincture is? Thanks 🙂

      • Tincture is a form of an extract.

  5. Hi:)
    I have a question about Horsetail and breastfeeding. I see you do not take it while pregnant or breastfeeding. I have read this elsewhere too. I’m a bit confused, I was going to order Dr Christopher’s calcium tea, then I realized I could just make it myself at a much better price with bulk herbs from Mountain Rose. So I’ve ordered the herbs, comfry, horsetail, oatstraw, raspberry…a few others since while bf i drink nettle and raspberry regularly anyway…
    i went on the Dr Christopher’s legacy page and found that this combo of herbs is something he would prescribe to help heal teeth and grow stronger teeth in children and he also advised pregnant and breastfeeding women to take it. so I’m all excited about making this formula myself with a recipe I found but now I’m concerned about the Horsetail. Has anyone taken Dr Christopher’s calcium formula while pregnant or bf? I’m wondering if I should just leave the comfry (sp?) and horsetail out and just make a mouth wash with those herbs to add to my teeth healing regiment.
    does anyone know anything about it? Any advice would be greatly appreciated! 🙂
    Ashley

    • I can’t speak on the pregnancy subject, but I do know from personal experience that it does help with teeth and gum issues. I used the tincture.

    • Horsetail contains small amounts of nicotine. This, therefore, makes it unadvisedable to use during pregnancy and breastfeeding and in children.

  6. I just read about this herb and its healing potential for osteoporosis. I have osteopenia. How would I use this herb long term?

  7. I am confused about horsetail and kidney stones. I get calcium oxalate stones so I usually have to avoid greens and things with heavy tannins. I thought this was good for them but you said do not take it if you have stones. I never know when they may be forming so what do you recommend? Thanks so much. I want to live healthy but am afraid of greens, sincerely, Deb

    • As I understand it, eating dark leafy greens – like kale, collard greens, swiss chard – are very good to eat to help keep calcium in your bones where it belongs. Otherwise you end up with things like bone spurs (& perhaps the calcium oxalate stones) that means calcium is being leached out of your bones.

    • Have you checked your blood calcium levels? If 10 or above, you should check your parathyroid levels as well, because if they are elevated as well, you have hyperparathyroidism which causes osteopenia and osteoporosis. If you have that, you need surgery to remove the bad parathyroid to regain your normal blood calcium levels. This happened to me, and I’m now rebuilding my bones after my surgery.

    • You might want to get an herbal mixture to get rid of kidney stones.

  8. I found it use full to know the use and try find some in my locality central London.

  9. Hi Katie
    I want to use the horsetail on blisters, when I do bars in crossfit I get a lot of blisters on my hands and because of that I have to stop my training until they get better and dry, I need something that can dry them super fast. In your recipe you mention plantain, is that the actual plantain? The whole plantain? Just the inside or out? Or is an oil?
    I’m also going to use tea tree oil for it, maybe that can help to dry faster. But I also want to try the horsetail recipe .
    Pleaseee help me with this !!! Thank you

    • Also try weight training gloves, helped mine.

  10. Hi Katie,

    Do you recommend liquid extract or tincture form of horsetail? I am unsure of the difference between the two– can you clarify?

    Also, do you know of a reputable company that ships to the UK?

    Thanks for this great post. Looking forward to getting some.

    • Either should work, but you can actually use the pure herb and either make your own tincture or blend in to smoothies

      • Hi Katie, I’ve posted something several times and have not received a reply yet. I’m sure u have lots to reply to so I’m sorry if I’m a pest 🙁 I am losing my hair on the right side of my head and am trying to learn where I can get the horsetail I need for a hair rinse. I have Natures Answer Horsetail liquid, 2000mg. Can I use that? And what is tincture? Thank u Katie. I’m desperate.

        • The horsetail liquid should work- a tincture is just a mixture of herbs that has been preserved in alcohol or glycerine. If you are losing your hair though, have you thought about seeing a naturopathic doctor?

        • Hi, I suffered with a large degree of rapid hair loss a year ago from stress and due to the meds I take. I take horsetail capsules (Holland & Barratt ( plus Selenium and Biotin.
          The combination of all 3 has made a huge difference! My hair stopped falling out and started growing back after 3 months.

          I also add coconut oil (KTC) to my daily diet.
          Hope that helps and good luck 🙂

          • Hi, I have been suffering from Alopecia for two years, I have read everything i can get my hands on, but do you think this will help increase my chances of my hair growing back, it’s starting to come back now like baby hair, I just want to give it every chance possible

      • Can I use horsetail topically while nursing? It’s for eczema on my hand. Thanks!

        • Christina,
          I’ve had eczema on my hands for over 25 years. Last year I had a Chemical allergy skin test done. It’s called a T.R.U.E. test. It has to be done by your allergy doctor I believe but it helped me finally clear up my eczema. I found out I was allergic to such everyday things as rubber and disperse blue dye (it’s in a lot of blue, grey and black synthetic clothes! Not to mention the eczema drug I was prescribed and naturally parabens and lanolin, etc. Now when I get a rare flare up, I usually know why.
          Hope that helps, Toni

  11. i take ‘ all day energy greens ” and i have noticed my hair in places is turning dark , one of the ingredients is horsetail i would like your comment and if this is what is helping the hair change color how can i accelerate the process thank you

  12. Horsetail grows in my backyard. I need to know whether to use it only in its dry state, or can it be used in a green, freshly harvested state? It is so prolific that I’m pulling it as it crosses ‘baracades’ into unapproved territory. New green, mature green, or dried…please respond.

    • I’ve read online (while researching silica) that the fresh and/ or ground state are used for polishing tin, so not to be taken internally or you could damage your insides. You could make a tea or throw in the bath for a soak.

  13. Horsetail + horseradish leaves or either alone boiled in water. The water is the best pesticide for plants ever. Have you ever seen bugs on either?

  14. Hi,
    This is so interesting, thanks Katie!!
    Like others I am over-run by Horsetail and it grows up to 5feet tall in the paddock at the bottom of the garden and I pull it out daily in the garden itself!!
    I have a dog with a slight incontinence problem and I’m running out of options to keep the old boy going 🙁 Other than this a few old bones he is a great lad and not ready to meet his maker yet! I would love to try and help him with what is essentially a weed in the garden but again as above need to know how I use it in it’s raw form to make a tea or infusion?
    Can I use it fresh or does it have to be dry?
    What Dosage would I use for 27KG Border CollieX?
    I have also read elsewhere that you can use Goldenrod with Horstail, again what I grow in the garden!
    If Combining with Horstail how much Goldenrod would I use and how would I use it?
    I also read that Nettles can be used in conjunction to help the bones (again Plentiful here!)
    How would I use the nettles with it?
    Any help or advice would be simply brilliant and very much appreciated.
    And of course you’d be helping to keep my old best friend going for a little bit longer!! 🙂
    Thanks
    Higgy

  15. how do we know the difference between horsetail and the great horsetail plant as we’ve heard the latter is poisonous?

  16. Interesting, I used horse tail for kidney stones. I had them in both kidneys about 3 years. ago. My mother-in-law has it growing in her front yard. She cut some and I used it for making tea. Washed it real well and boiled it. I don’t recall how long I drank it in between appointments. When I went to the doctor they were surprised, one kidney was completely free of stones and the other the stone had decreased in size. I still got it obliterated but only had to endure the procedure on one kidney instead of both. I’ve been curious of other uses for horse tail and came across your blog. Thanks for the info.

  17. My 4 week old baby has reflux and spitting issues.she is not able to sleep in her back for poor esophageal / stomach digestion.i am exclusively breast feeding.can I use horsetsil in moderate?

  18. There seems to be two horsetail herb plants. Which is which, the right one or are they the same? There is the one that looks soft and green like a bottle brush, then the other looks like long tails that grow straight up. What is the difference and when ordering this herb how do I know which one I got??????

  19. I’m currently drinking a stong horsetail tea infusion at least once a day to help with a hair loss issue. The silica in the tea seems to strengthen the hair and assist in promoting re-growth. My nails have never been nicer either.

  20. i just started yesterday, half a cup of dried horsetail herbs with hot water at night. Hoping it will help my hair grow back and skin become clearer

  21. Plantain like green banana, or plantago plantain, and what part? The leaves or do you make the paste out of psyllium fiber, the seeds make a pretty thick paste when they get wet.

  22. Hi. I started reading about Horsetail to learn about its use for hair loss due to my long hair thinning on one side of my head. With what I’ve learned I’d like to try it for several other medical problems I’m dealing with. I ordered supplements and extract, and would like to know….can I use the extract in a tea or should I be using the herb? Also, what is tincture? (Sp?). I have TBI so it’s confusing. Thank you so much 🙂

    • Refer to the above answer by Katie (Wellness Mama) that says a tincture is just a mixture of herbs that has been preserved in alcohol or glycerine. I would use the herb in a tea or just take the supplement.

  23. Do you have any solutions for UTIs caused by group b strep? I keep getting them and would like to find another solution

    Thanks for your help.

    Tricia

    • Hello. I use to suffer from uti all the time. The only thing that cured, yes cured me was apple cider vinegar. 1 to 2 tablespoons 3 times a day. Trust me, it works.

    • Baking soda (1/2 tsp – 1 tsp may help) or D-Mannose. I’ve read these remedies are helpful for Urinary Tract Infections.

  24. HI, I’ve used horsetail as a herbal tea to settle upset stomach several times and it seems to work well. I do wonder if I am using the best species and if I could identify which is the best I would feel better about using it

  25. My mom use to make a solution from horsetail to use as a bathing compress on poison ivy when I was young which helped. Now as an adult I have been battling with eczema for about 10 years. Would the horsetail solution compresses help the eczema? Thank you!

    • Epsoms salts or bentonite clay wraps have helped some with eczema. Or borax in your bath water. Hydrogen peroxide in the water would be helpful too.

  26. I have horsrtail plants in my garden, but have never used for medicinal purposes. As my hair started falling, I’ll make a try

  27. Hi there, quick question: I make a gallon of tea using a cup of lemon grass, half a cup peppermint leaf, and a half cup horsetail. I’ve never used horse tail in the past but wanted to give it a try for the silica properties and the immune properties. I just read that it may not be safe to give to children and I just wanted to find out if you think that this may be a bit too much for a gallon of water because I don’t want to cause any deficiencies. During my brief time studying of herbalism, I saw that the herb was completely safe during pregnancy and lactation, but now I’m reading that info is different and may be unsafe. I just want to be sure that I don’t have to dump out my gallon of organic yummy tea 🙂
    thank you in advance.
    Have a great day,
    AmberJea

  28. I just bought horsetail capsules at Whole Foods.

  29. Hi, I have a liquid made up of 50/50 horsetail and oat straw. I intended to take the liquid (5ml in water daily) until I discovered it may not be totally safe to consume whilst breastfeeding? I’m needing another way to use it now. If I used it externally on my hair, how much (ml) would I use and how to use it? Thanks in advance!

  30. I had no idea it helps so many ailments!!!!!!!!!!

    • lol, yeah thats a lot of uses, i bought some silica from the natural food store, trying a new herb this year, hope it helps with dry hair loss spots on the top of head, looking forward to helping with improved vision.

  31. Thanks for this info on horsetail. I was walking today here in Vancouver Canada and picked a few stems. When making a tea – for both drinking as well as for a jphaur conditioner -, do you use only the leaves/needles or the stems as well?

  32. How long can you take this? I just got a bag of the horsetail herb from Amazon and have been drinking it as tea. I add a little sweetener and it is really delicious. Some websites say not to take this long term. Can anyone help me out as to how much a day is safe and can I drink it everyday? Has anyone had an issue with it interfering with their Thiamine? Thanks

  33. Is it safe to take Horsetail topically while pregnant? Need Advice

    I am using this body Merry stretch mark cream and one of the ingredients is horsetail. I am just wondering should I stop taking the cream. I am 20weeks pregnant no health issues.
