Cleveland Clinic is a non-profit tutorial medical middle. Advertising on our website helps assist our mission. We don’t endorse non-Cleveland Clinic services or products. Policy

While fast and straightforward, popping an over-the-counter ache capsule isn’t all the time the only option. Sometimes, an ice pack or a heating pad is the best way to go as a substitute. Other occasions, kinesio tape is your greatest wager. Gentle stretching or yoga would possibly assist. Maybe what you want is an acupuncturist or chiropractor’s contact. In some circumstances, you and your physician might think about prescription medicines, or a process like dry needling or radiofrequency ablation. And some approaches to ache administration are well-studied, whereas others stay experimental.

But it doesn’t matter what you do, your expertise is more likely to differ from different peoples’ as a result of ache isn’t static or customary.

And it may all get fairly complicated.

Arnica could be notably puzzling. On the one hand, many individuals, and a few research, argue that it’s an efficient ache reliever. On the opposite hand, these research are fairly restricted. Moreover, the phrase “poisonous” pops up loads if you seek for details about it. But you can even use it to taste meals? What the heck?!

We spoke to chiropractor Candice Price, DC, to study what arnica is, the way it might relieve ache and how you can use it safely and successfully.

What is arnica?

Arnica is a perennial, herbaceous plant with yellow or orange flowers that’s native to North America and most of Europe, with some species rising in India, Far East Russia and Japan. It’s been a participant in conventional natural drugs for hundreds of years — notably the Arnica montana species, which grows in Europe. That’s the species you’re almost certainly to come across in industrial merchandise.

Modern makes use of of arnica embrace the remedy of muscle pain (myalgia), joint pain (arthralgia), irritation and bruising.

While typically secure and arguably effective when utilized topically, arnica is not any delicate flower. The herb incorporates a toxin known as helenalin, which is lethal if consumed in massive portions. Arnica can be used to taste meals, however some nations have banned culinary use completely, in an try to stop unintended poisoning.

As you’ll see, on the subject of arnica, a mixture of your private medical historical past and the herb’s preparation determines how secure it’s.

What does arnica do?

As Dr. Price places it, “Arnica is a remedy that’s been used for centuries for a reason. There must be something to it that’s beneficial.”

But what, precisely? The truth is, our understanding of arnica stays restricted. It’s a posh little plant!

“There are about 150 different bio-active components in arnica,” Dr. Price provides. “So, there are a lot of chemicals in there that have varying effects.”

While researchers have examined many of those elements in isolation, Dr. Price explains that we haven’t essentially studied the best way these elements come collectively in arnica to work on a human cell.

“Most of that research has been done in laboratory settings, on cells that have been taken from humans,” she says. “They’re just starting human research in a clinical setting.”

That means our understanding of arnica is stitched collectively based mostly on what we find out about its varied elements and the way they behave. It’s an imperfect understanding, nevertheless it’s a begin.

“We know, for example, that some components of arnica are antioxidant and cytoprotective — meaning they protect your cells,” Dr. Price continues. But she notes that different elements — like helenalin — are cytotoxic. Again: There’s nonetheless there’s loads of analysis to do if we wish to actually perceive arnica’s potential.

How does arnica work?

We might not absolutely perceive arnica, however we do know that it relieves ache when utilized to the pores and skin. In truth, a 2007 study recommended it really works simply as nicely for hand osteoarthritis as topical NSAIDs.

“Arnica is very similar in how it works and functions to diclofenac and ibuprofen,” Dr. Price says.

In some research, individuals who used arnica had barely fewer adverse negative effects than the individuals utilizing topical NSAIDs, however different research discovered the precise reverse.

Bottom line (once more): We want extra analysis to totally perceive arnica’s capability to alleviate ache.

Forms arnica is available in

There are many various methods to organize arnica, however they aren’t created equal. Topical preparations are far and away the perfect and most secure approach to make use of the herb.

As Dr. Price states, “Oral formulations are usually riskier. I don’t advise my sufferers to take these as a result of there’s much more threat concerned.

“Arnica is regulated like a supplement, not a medication. That means there isn’t a consistent dosage recommendation.” Not solely is arnica under-researched, however Dr. Price additionally notes that the therapeutic dosing analysis that does exist is funded by arnica producers.

Topical preparations

Topical arnica merchandise like lotions, gels, foams, salves, roll-ons and ointments are the most typical, most secure and only approach to make use of the herb.

In truth, it’s potential you’ve used arnica with out realizing it.

“A lot of the FDA-regulated topical pain relief products and massage oils that exist out there have arnica in them,” Dr. Price says. “It’s snuck into a lot of products that people don’t realize.” That’s dangerous information for people who find themselves allergic to the herb (extra on that in a bit), however doubtlessly excellent news for the remainder of us.

That’s as a result of, in 2021, a review of studies on natural therapies for osteoarthritis concluded that arnica gel is about as efficient as topical NSAIDs for irritation and ache aid. There’s one huge caveat, although: The findings weren’t clinically vital.

“I usually recommend arnica for reducing bruising and joint or muscle aches, but that recommendation is based on my patients’ experiences, not the current quality of research on the topic” Dr. Price states.

While not strict concerning the model of arnica her sufferers use, she does encourage buying from producers which might be situated within the U.Ok. or European Union, as they’re extra tightly regulated than corporations producing arnica merchandise within the United States.

Homeopathic preparations

Depending on the place you go on the web, chances are you’ll learn that medical doctors advocate homeopathic arnica therapies. Maybe some medical doctors do, however they’re doing so regardless of an absence of scientific proof suggesting that homeopathic cures are safe or effective.

Dr. Price is easy about homeopathic arnica therapies: “You can try them at your own risk, but they’re not medically advised.”

Homeopathic medicines are made by diluting minute portions of the lively ingredient, a lot in order that it might not even be detectable. Most homeopathic arnica is available in pill, tincture or dissolvable-pellet type.

Here’s the catch: If there are detectable ranges of helenalin within the product you’re utilizing, you’re susceptible to well being issues starting from vomiting to organ harm and dying. In different phrases, the most secure homeopathic arnica merchandise … include subsequent to no arnica.

Dr. Price provides, “There are a lot of homeopathic products out there made by less-than-reputable sources,” it’s most likely greatest to avoid these merchandise.

Dietary dietary supplements and infusions

If you go looking for arnica merchandise, chances are you’ll discover them obtainable in unfastened flower or tea type. While arnica is typically used to taste meals, it’s toxic, and — in accordance with the U.S. Food & Drug Administration (FDA) — not secure to eat in its pure type. In truth, some nations prohibit its use in meals altogether.

The U.S. authorities doesn’t regulate arnica, so you may’t be fully positive how a lot of the poisonous materials you’re consuming if you eat or drink it. More on that later.

DIY merchandise

We all love a great DIY venture, however on the subject of arnica, steer clear of the selfmade stuff.

“I recommend against buying arnica products from an unknown retailer, or from a random ‘mom and pop’ who cultivate the flower and make arnica tinctures at home,” Dr. Price stresses. Aside from high quality management issues, main producers of arnica and merchandise that include arnica usually tend to be constant of their dosing.


In 2020, the FDA despatched warning letters to a number of corporations promoting injectable homeopathic merchandise, together with one firm that was promoting injectable arnica.

In these letters, the FDA defined that injectable medication are far riskier than topical or ingested merchandise, as a result of they “are delivered directly into the body, sometimes directly into the bloodstream, and therefore, bypass some of the body’s key defenses against toxins and microorganisms that can lead to serious and life-threatening conditions.”

If you see an organization — pharmaceutical or in any other case — promoting arnica injections, keep away from them fully. 

Risks and negative effects of arnica

When it involves deciding if arnica is the correct alternative for you, it’s essential to think about it such as you would another anti-inflammatory or ache drugs. It’s not proper for everyone and could be harmful if made or used improperly.

Do not take arnica by mouth

While arnica is usually used to taste meals, its cytotoxic properties render it toxic in massive quantities. For that cause, the FDA has labeled the herb as unsafe, and the Canadian authorities has fully banned its use in meals.

Depending on how a lot arnica you ingest, you may expertise the next:

  • Irritation and/or harm to your pores and skin, mouth, throat and abdomen.

  • Death.

While homeopathic preparations of arnica (accurately manufactured) are unlikely to trigger negative effects, (1) there’s no scientific proof that they work and (2) as a result of it’s an unregulated substance, you may’t make sure that the product you’re utilizing is secure.

Who shouldn’t take arnica?

Arnica lotions and gels could also be helpful, however — identical to over-the-counter ache medicines — they’re not for everyone. You shouldn’t use arnica if:

  • You’re allergic to vegetation within the Asteraceae and Compositae households. If you’re allergic to ragweed, sunflowers, marigolds, chrysanthemums or daisies, there’s a great likelihood you’re allergic to arnica, too.
  • You’re already utilizing merchandise that include arnica. Because we don’t have a transparent understanding of dosing, it’s greatest to not use a number of arnica merchandise directly.
  • You take corticosteroids, blood strain remedy, anticoagulants or sure natural dietary supplements. Arnica has over 150 bioactive elements, so it’s little surprise that it doesn’t play properly with all medicines.
    • Doctors prescribe corticosteroids for irritation, so until yours offers you the all-clear, it is best to keep away from doubling up.
    • If your physician is treating you for hypertension, arnica is a no-go: It may make your remedy much less efficient.

  • You have extreme liver or kidney illness. Our liver and kidneys assist us filter out waste and poisonous substances. If yours aren’t performing as they need to, for no matter cause, arnica most likely isn’t a threat value taking — not less than, not with out consulting along with your liver physician (hepatologist) or kidney physician (nephrologist) first.
  • You’re about to have, or lately had, surgical procedure. Because arnica can skinny your blood, medical doctors advocate you cease utilizing arnica not less than two weeks earlier than present process surgical procedure and keep off it till your surgeon offers you the all-clear.
  • Your pores and skin is damaged. While there are researchers actively working to find out if arnica is perhaps helpful for post-surgical incisions, we don’t but know what (moreover stinging) would occur if a gel or cream preparation have been to get beneath one’s pores and skin. Given the herb’s toxic nature, it’s greatest to keep away from utilizing it on damaged pores and skin, whether or not it’s from a wound or a dermatological situation like eczema or psoriasis.
  • You’re pregnant or breastfeeding (chestfeeding). While arnica has clear pain-relieving properties, as we’ve emphasised, there’s additionally loads about it that we nonetheless don’t know. For that cause, it’s essential that you simply don’t use arnica in case you’re pregnant or breastfeeding (chestfeeding).
  • Babies and kids. DO NOT belief what you learn on homeopathy web sites about the advantages of arnica for infants and kids. If you uncover that your child’s gotten into an arnica product, it is best to contact poison control instantly.

If you aren’t a great candidate for topical arnica for a number of of the explanations listed above, don’t despair! There are loads of different ache aid strategies (past conventional NSAIDs) you could strive.

“People who want something that’s a little bit more natural and holistic for pain relief can look into chiropractic care, osteopathic manipulation, physical therapy, massage, acupuncture, yoga, meditation and even psychotherapy for pain management,” Dr. Price advises. “There are all sorts of different bio-psychosocial interventions you can explore with your healthcare provider.”
