Arnica, a perennial herb belonging to the sunflower family (Asteraceae), has a rich history in traditional medicine, particularly for its pain-relieving and anti-inflammatory properties. Originating from regions like East Asia, Europe, the northern United States, and Canada, arnica, especially the Arnica montana species, has been utilized for centuries. While typically applied topically, arnica tea, made from dried arnica flowers steeped in hot water, has gained popularity. This article explores the potential benefits and side effects of arnica tea, its various uses, and safety considerations.
Traditional Uses and Reported Benefits
Arnica has been a staple in herbal medicine for centuries, traditionally employed to address various ailments, especially those related to aches and pains. Mexican traditional medicine, for instance, has embraced arnica tea for relieving stomach troubles, fevers, and nervous disorders. Many people enjoy arnica tea for its stress-relieving, calming effects. The tea is often favored for its earthy flavor and relaxing properties. Proponents suggest it can aid in stress relief, pain management, reducing inflammation, promoting wound healing, and improving circulation. Herbal medicine has long valued arnica for its anti-inflammatory and pain-relieving properties. Arnica has long been used for relieving pain, particularly muscle soreness and arthritis pain. Applied topically, arnica has long been used to promote wound healing.
Making Arnica Tea and Incorporating It into Your Diet
Making arnica tea at home is surprisingly simple. The basic recipe involves steeping dried arnica flowers in hot water.
Basic Arnica Tea Recipe:
- Boil approximately 3 cups of water.
- Remove the water from the heat source.
- Add 1 tablespoon of dried arnica flowers.
- Steep for the desired time.
Arnica tea can be enjoyed on its own or sweetened with honey.
Variations:
- Ginger Arnica Tea: Add fresh ginger to the steeping process for an extra boost.

- Tea Syrup: Simmer a 1:1 ratio of sugar to water with the tea (using a strainer or tea ball) until the sugar dissolves. Once cooled, store the syrup in cleaned containers.
- Smoothies: Add cooled arnica tea to smoothies for additional health benefits.
The best way to store any kind of loose herbal tea is to keep it in an airtight, opaque container, protected from moisture, air, light, and heat. Most herbal teas, when stored properly, have a shelf life of around 1.5 years.
Potential Risks and Side Effects
While arnica tea offers potential benefits, it's crucial to be aware of the potential adverse effects. A word of warning: arnica contains compounds such as helenalin and dihydrohelenalin which can be toxic when ingested in large amounts. In large amounts, arnica tea can become toxic due to the presence of helenalin and dihydrohelenalin.
- Toxicity: Arnica tea is considered toxic in large amounts due to the presence of helenalin and dihydrohelenalin.
- Stomach Irritation: If arnica tea isn’t properly diluted, large quantities can cause irritation to your stomach.
- Pregnancy: You should avoid arnica tea in pregnancy. Similarly, using arnica ointment topically isn’t advised during pregnancy.
- Medication Interactions: If you’re on certain medications such as blood thinners, you’ll want to avoid drinking arnica tea.
- Allergic Reactions: Arnica is related to ragweed and other members of the Asteraceae/Compositae family of plants. If you’re allergic to ragweed, sunflowers, marigolds, chrysanthemums or daisies, there’s a good chance you’re allergic to arnica, too.
Depending on how much arnica you ingest, you could experience the following:
- Irritation and/or damage to your skin, mouth, throat and stomach.
- Vomiting.
- Diarrhea.
- Shortness of breath.
- Rapid heartbeat.
- High blood pressure.
- Heart damage.
- Organ failure.
- Coma.
- Death.
Forms of Arnica and Their Uses
Arnica is available in various forms, each with its own safety profile and application:
- Topical Preparations: Creams, gels, foams, salves, roll-ons, and ointments are the most common, safest, and most effective way to use arnica. In 2021, a review of studies on herbal therapies for osteoarthritis concluded that arnica gel is about as effective as topical NSAIDs for inflammation and pain relief.
- Homeopathic Preparations: Homeopathic arnica comes in tablet, tincture, or dissolvable-pellet form. Homeopathic medicines are made by diluting minute quantities of the active ingredient, so much so that it may not even be detectable.
- Dietary Supplements and Infusions: Arnica products may be available in loose flower or tea form.
- DIY Products: It is recommended to avoid homemade arnica products due to quality control concerns.
- Injectibles: Avoid companies selling arnica injections, as injectable drugs are far riskier than topical or ingested products.
Who Should Avoid Arnica?
Arnica creams and gels may be beneficial, but they’re not for everybody. You shouldn’t use arnica if:

- You’re allergic to plants in the Asteraceae and Compositae families.

- You have a blood disorder.
- You have severe liver or kidney disease.
- You’re about to have, or recently had, surgery.
- Your skin is broken.
- You’re pregnant or breastfeeding.
- Babies and children.
Scientific Evidence and Research
While anecdotal evidence and traditional use support the benefits of arnica, scientific research is still evolving.
- Osteoarthritis: Applying an arnica gel twice daily for 3 weeks can reduce pain and stiffness and improve function in people with osteoarthritis in the hand or knee. It might work as well as ibuprofen.
- Post-operative Pain: Arnica has shown mixed effects on post-operative pain. Some studies have shown a significant reduction in pain after hand surgery or dental extraction, while others have reported no effect or even increased pain.
- Bruising: A few clinical trials suggest that topical arnica significantly reduces bruising compared with placebo or low-concentration vitamin K ointments.
- Anti-inflammatory Properties: In vitro studies show that arnica has antimicrobial and anti-inflammatory properties. Sesquiterpene lactones, the active constituents in arnica, have anti-inflammatory properties and inhibit binding of transcription factors AP-1 and NF-κB to DNA.
Mechanisms of Action
The beneficial impact of arnica on pain relief may be the result of its anti-inflammatory, anti-microbial, antioxidant, and immunomodulatory activities.
- Anti-inflammatory Properties: Arnica diminishes the expression of the intracellular cell adhesion molecule (ICAM-1) induced by TNF-α in endothelial cells and increases the anti-inflammatory macrophage population compared to pro-inflammatory macrophages in mice with injured skeletal muscles.
- Antimicrobial Properties: Arnica was routinely used for infection, especially dental and oral infections.
- Antioxidant Properties: The ethanol/water extract of arnica flowers, rich in flavonoids and phenolic acids, demonstrated high, Trolox-equivalent antioxidant capacity, oxygen radical absorbance capacity, and free radical-scavenging activity.
- Bioactive Components: Over 150 bioactive components have been identified in arnica, including sesquiterpene lactones, flavonoids, volatile oils, coumarins, helenalin, carotenoids, diterpene alcohols, arnidiol, pyrrolizidine alkaloids, phenolic acids, essential oils, oligosaccharides, and lignans.
Alternative Pain Relief Methods
If arnica is not suitable, there are alternative pain relief methods to explore.
“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.”
