5 Emerging Benefits and Uses of Yarrow Tea
Yarrow (Achillea millefolium) has been used for thousands of years for its potential health benefits. In fact, its genus name, Achillea, refers to the warrior Achilles in Greek mythology, as he used yarrow to treat his soldiers' wounds.
There are 140 different species of Achillea, which are characterized by their clustered flowers and hairy, aromatic leaves.
Studies indicate that this plant may have various benefits as an herbal tea, extract, or essential oil.
Here are 5 emerging benefits and uses of yarrow tea.
1. May Enhance Wound Healing
Since the times of Ancient Greece, yarrow has been used in poultices and ointments to treat wounds.
One animal study found that yarrow leaf extracts exhibited anti-inflammatory and antioxidant properties, both of which aid wound healing.
Furthermore, this study noted that yarrow leaf extract may increase fibroblasts, which are the cells responsible for regenerating connective tissue and helping your body recover from injury.
Meanwhile, a 2-week study in 140 women observed that an ointment made from this herb and St. John's wort helped heal episiotomy sites, which are surgical incisions on the vaginal wall made during childbirth.
While these results are promising, it's unclear whether yarrow tea has the same effects. Thus, more studies are needed.
Studies suggest that yarrow leaf extract and ointment may boost wound healing. However, additional studies are needed on yarrow tea itself.
2. May Alleviate Digestive Issues
Yarrow has long been used to treat digestive issues like ulcers and irritable bowel syndrome (IBS), symptoms of which include stomach pain, diarrhea, bloating, and constipation.
In fact, this herb contains several flavonoids and alkaloids, which are plant compounds known to relieve digestive complaints.
In a study in rats, a yarrow extract tonic protected against stomach acid damage and demonstrated anti-ulcer properties.
Another animal study found that the flavonoid antioxidants in yarrow tea may fight digestive spasms, inflammation, and other IBS symptoms.
All the same, more research is needed.
Animal studies show that yarrow tea may provide several digestive benefits, such as combatting ulcers and IBS symptoms.
3. May Help Reduce Symptoms of Depression and Anxiety
The flavonoids and alkaloids in yarrow tea may alleviate symptoms of depression and anxiety.
Studies demonstrate that plant-based alkaloids like those in yarrow tea reduce the secretion of corticosterone, a hormone that's high during chronic stress.
One study found that yarrow essential oils administered orally to rats reduced anxiety and encouraged daily mental and physical activity.
However, these results are preliminary and don't necessarily apply to anxiety in humans. Furthermore, you should not ingest essential oils.
Thus, human research on yarrow tea is needed.
Yarrow tea contains flavonoids and alkaloids that may relieve symptoms of depression and anxiety. All the same, human studies are necessary.
4. May Aid Brain Health
Yarrow has been shown to aid certain brain disorders, such as multiple sclerosis, Alzheimer's, Parkinson's, and encephalomyelitis — inflammation of the brain and spinal cord caused by a viral infection.
Plus, a rat study found that yarrow's antioxidants have anti-seizure effects, making this herb a promising treatment for people with epilepsy.
Additional rat studies indicate that this plant may prevent symptoms of Alzheimer's and Parkinson's diseases, such as memory loss and impairments in physical movement and muscle tone.
However, these studies are preliminary and limited to animals.
Research suggests that yarrow may reduce symptoms of certain brain disorders, such as epilepsy, multiple sclerosis, Alzheimer's, and Parkinson's.
5. May Fight Inflammation
While inflammation is a natural bodily response, chronic inflammation can lead to cell, tissue, and organ damage.
Yarrow may reduce skin and liver inflammation, which could help treat skin infections, signs of skin aging, and non-alcoholic fatty liver disease.
A test-tube study determined that yarrow extract not only decreased inflammation but also increased skin moisture.
Other test-tube studies reveal that this extract may reduce liver inflammation — as well as fight fevers.
Although these results are promising, human research is needed.
Yarrow tea may reduce both liver and skin inflammation, but research is currently limited.
Precautions and Potential Concerns
While yarrow is likely safe for most individuals, some people should practice caution.
Women who are pregnant or breastfeeding should not ingest yarrow, as it can trigger miscarriages and affect the menstrual cycle.
Furthermore, people with bleeding disorders or who take blood thinners should avoid yarrow because it may increase the risk of bleeding.
On that same note, this herb should not be consumed for 2 weeks before and after surgery due to a higher risk of bleeding.
What's more, yarrow may cause an allergic reaction in people allergic to ragweed and other related plants.
Yarrow is safe for most individuals. However, you should avoid it if you have a bleeding disorder or are pregnant, breastfeeding, undergoing surgery, or allergic to ragweed.
How to Add It to Your Diet
Yarrow comes in several forms, including powders, ointments, tinctures, extracts, and dried leaves and flowers.
The leaves and flowers can be made into tea by steeping 1–2 teaspoons (5–10 grams) in boiling water for 5–10 minutes. You can purchase the dried herb, as well as premade tea bags, from various health stores or online.
You can also add yarrow powder to smoothies, water, and juice — and use its essential oils in baths, lotions, or diffusers.
Keep in mind that insufficient evidence exists to establish dosage guidelines for yarrow tea or other products. As such, you should always refer to product labels and consult a healthcare practitioner before using this herb.
You can buy dried yarrow or premade tea bags online or in various health stores. This herb also comes in other forms, such as tinctures, ointments, extracts, and powders.
The Bottom Line
Yarrow has been used medicinally since ancient times, including as an herbal tea.
Research shows that its plant compounds may benefit wound healing, digestive issues, brain ailments, and other conditions. However, further studies in humans are necessary.
If you're interested in drinking yarrow tea, consult a medical professional to make sure it's right for you.

The Biden-Harris transition team identified COVID-19, economic recovery, racial equity and climate change as its top priorities. Rivers are the through-line linking all of them. The fact is, healthy rivers can no longer be separated into the "nice-to-have" column of environmental progress. Rivers and streams provide more than 60 percent of our drinking water — and a clear path toward public health, a strong economy, a more just society and greater resilience to the impacts of the climate crisis.

While health officials encourage hand-washing to contain the pandemic, at least <a href="https://closethewatergap.org/" target="_blank">2 million Americans</a> are currently living without running water, indoor plumbing or wastewater treatment. Meanwhile, <a href="https://www.theguardian.com/us-news/2020/jun/23/millions-of-americans-cant-afford-water-bills-rise" target="_blank">aging water infrastructure is growing increasingly costly for utilities to maintain</a>.

Last spring, <a href="https://nymag.com/intelligencer/2020/03/coronavirus-stimulus-bill-explained-bailouts-unemployment-benefits.html" target="_blank">Congress appropriated more than $4 trillion</a> to jumpstart the economy and bring millions of unemployed Americans back to work. Additional federal assistance — desperately needed — will present a historic opportunity to improve our crumbling infrastructure, which has been <a href="https://www.theguardian.com/us-news/2020/jun/23/millions-of-americans-cant-afford-water-bills-rise" target="_blank" rel="noopener noreferrer">grossly underfunded for decades</a>.</p><p>A report by my organization, American Rivers, suggests that <a href="https://s3.amazonaws.com/american-rivers-website/wp-content/uploads/2020/07/09223525/ECONOMIC-ENGINES-Report-2020.pdf" target="_blank" rel="noopener noreferrer">Congress must invest at least $50 billion</a> "to address the urgent water infrastructure needs associated with COVID-19," including the rising cost of water. This initial boost would allow for the replacement and maintenance of sewers, stormwater infrastructure and water supply facilities.</p>
Economic Recovery<p>Investing in water infrastructure and healthy rivers also creates jobs. Consider, for example, that <a href="https://tinyurl.com/y9p6sgnk" target="_blank">every $1 million spent on water infrastructure in the United States generates more than 15 jobs</a> throughout the economy, according to a report by the Value of Water Campaign. Similarly, <a href="https://tinyurl.com/yyvd2ksp" target="_blank">every "$1 million invested in forest and watershed restoration contracting will generate between 15.7 and 23.8 jobs,</a> depending on the work type," states a working paper released by the Ecosystem Workforce Program, University of Oregon. Healthy rivers also spur tourism and recreation, which many communities rely on for their livelihoods. According to the findings by the Outdoor Industry Association, which have been shared in our report, "Americans participating in watersports and fishing spend over <a href="https://s3.amazonaws.com/american-rivers-website/wp-content/uploads/2020/06/30222425/Exec-summary-ECONOMIC-ENGINES-Report-June-30-2020.pdf" target="_blank">$174 billion</a> on gear and trip related expenses. And, the outdoor watersports and fishing economy supports over <a href="https://s3.amazonaws.com/american-rivers-website/wp-content/uploads/2020/06/30222425/Exec-summary-ECONOMIC-ENGINES-Report-June-30-2020.pdf" target="_blank">1.5 million jobs nationwide</a>."</p><p>After the 2008 financial crisis, Congress invested in infrastructure to put Americans back to work. The American Recovery and Reinvestment Act <a href="https://thehill.com/blogs/congress-blog/economy-a-budget/25941-clean-water-green-infrastructure-get-major-boost" target="_blank">of 2009 (ARRA) allocated $6 billion</a> for clean water and drinking water infrastructure to decrease unemployment and boost the economy. More specifically, <a href="https://www.conservationnw.org/news-updates/us-reps-push-for-millions-of-restoration-and-resilience-jobs/" target="_blank" rel="noopener noreferrer">an analysis of ARRA</a> "showed conservation investments generated 15 to 33 jobs per million dollars," and more than doubled the rate of return, according to a letter written in May 2020 by 79 members of Congress, seeking greater funding for restoration and resilience jobs.</p><p>Today, when considering how to create work for the <a href="https://www.bls.gov/news.release/pdf/empsit.pdf" target="_blank" rel="noopener noreferrer">10.7 million</a> people who are currently unemployed, Congress should review previous stimulus investments and build on their successes by embracing major investments in water infrastructure and watershed restoration.</p>
Racial Justice<p>American Rivers also recommends that Congress dedicate <a href="https://s3.amazonaws.com/american-rivers-website/wp-content/uploads/2020/07/09223525/ECONOMIC-ENGINES-Report-2020.pdf" target="_blank" rel="noopener noreferrer">$500 billion for rivers and clean water over the next 10 years</a> — not just for the benefit of our environment and economy, but also to begin to address the United States' history of deeply entrenched racial injustice.</p><p>The <a href="https://www.epa.gov/npdes/sanitary-sewer-overflows-ssos" target="_blank" rel="noopener noreferrer">23,000-75,000 sewer overflows</a> that occur each year release up to <a href="https://www.americanrivers.org/2020/05/fighting-for-rivers-means-fighting-for-justice/#:~:text=There%20are%20also%2023%2C000%20to%2075%2C000%20sanitary%20sewer,to%20do%20with%20the%20mission%20of%20American%20Rivers." target="_blank" rel="noopener noreferrer">10 billion gallons of toxic sewage</a> <em>every day</em> into rivers and streams.

In some communities of color, incessant flooding due to stormwater surges or <a href="https://www.ajc.com/opinion/opinion-partnering-to-better-manage-our-water/7WQ6SEAQP5E4LGQCEYY5DO334Y/" target="_blank" rel="noopener noreferrer">combined sewer overflows</a> has gone unmitigated for decades.</p><p>We have historically treated people as separate from rivers and water. We can't do that anymore.

We also must go further to ensure that local leaders have a seat at the decision-making table. To this end, the Biden-Harris administration should restore <a href="https://www.epa.gov/cwa-401#:~:text=Section%20401%20Certification%20The%20Clean%20Water%20Act%20%28CWA%29,the%20United%20States.%20Learn%20more%20about%20401%20certification." target="_blank">Section 401 of the Clean Water Act</a>, which was undermined by the <a href="https://earthjustice.org/news/press/2020/tribes-and-environmental-groups-sue-trump-administration-to-preserve-clean-water-protections#:~:text=Under%20Section%20401%20of%20the%20Clean%20Water%20Act%2C,seeks%20to%20undermine%20that%20authority%20in%20several%20ways%3A" target="_blank">Trump administration's 2020 regulatory changes</a>.

Climate Resilience<p>Of course, the menacing shadow looming over it all?

In other words, the most obvious and dire impacts of climate change are evidenced in profound changes to our rivers and water resources. You've likely seen it where you live: Floods are more damaging and frequent. Droughts are deeper and longer. Uncertainty is destabilizing industry and lives.</p><p>By galvanizing action for healthy rivers and managing our water resources more effectively, we can insure future generations against the consequences of climate change. First, we must safeguard rivers that are still healthy and free-flowing. Second, we must protect land and property against the ravages of flooding. And finally, we must promote policies and practical solutions that take the science of climate disruption into account when planning for increased flooding, water shortage and habitat disruption.</p><p>Imagine all that rivers do for us. Most of our towns and cities have a river running through them or flowing nearby. Rivers provide clean drinking water, irrigate crops that provide our food, power our homes and businesses, provide wildlife habitat, and are the lifeblood of the places where we enjoy and explore nature, and where we play and nourish our spirits. Healthy watersheds help <a href="https://news.un.org/en/story/2020/03/1059952" target="_blank" rel="noopener noreferrer">mitigate</a> climate change, absorbing and reducing the amount of carbon in the atmosphere. Healthy rivers and floodplains help communities adapt and build resilience in the face of climate change by improving flood protection and providing water supply and quality benefits. Rivers are the cornerstones of healthy, strong communities.</p><p>The more than <a href="https://archive.epa.gov/water/archive/web/html/index-17.html" target="_blank" rel="noopener noreferrer">3 million miles</a> of rivers and streams running across our country are a source of great strength and opportunity. When we invest in healthy rivers and clean water, we can improve our lives. When we invest in rivers, we create jobs and strengthen our economy. When we invest in rivers, we invest in our shared future.</p>
