Research-Backed Potential Benefits of Yarrow
1. May Enhance Wound Repair
Yarrow was used to manage wounds. It is proposed to do this by stopping bleeding and helping tissue repair. The plant got its botanic name, Achillea millefolium, from a Greek warrior. He used yarrow to manage his soldiers’ wounds in the Trojan War.
Yarrow contains several active properties. These include anti-inflammatory compounds, antioxidants, and flavonoids. All of these mix at once and are proposed to stimulate fibroblast activity (the cells that help repair damaged tissue). It then reduces discomfort and promotes blood clotting.
Although there is limited evidence on yarrow for wound repair, some early research shows positive results:
- A study on rats showed that yarrow extract has anti-inflammatory and antioxidant properties. These might help with its effects on wound repair.
- A study of 140 women found that an ointment with yarrow helped wounds repair. These wounds had been produced during childbirth.
Despite these findings, more robust research is needed on the wound-repairing effects of yarrow in humans.
2. May Alleviate Digestive Issues
Yarrow has been used for a long time to manage digestive problems. The plant’s flavonoids and alkaloids may help with these benefits.
IBS gives you abdominal pain, bloating, diarrhoea, and constipation. Animal research shows that yarrow’s flavonoids may have strong anti-spasmodic effects. This means it may ease stomach spasms. This may result in fewer IBS symptoms.
Yarrow has been used throughout history to aid digestion and help with indigestion. Its active compounds may boost saliva and stomach acid production. This might improve digestion overall.
- Colic and gastrointestinal spasms
Because of its anti-spasmodic activity, yarrow might ease colic and stomach spasms.
Though these benefits are only supported by traditional use and limited animal studies, we need more research. Only then can we confirm yarrow’s effectiveness for digestive problems in people.
3. May Help Reduce Symptoms of Depression and Anxiety
The flavonoids and alkaloids in yarrow may help reduce signs of depression and anxiety. They might control brain messenger activity. This might lead to less stress hormone release and soothing effects.
In rats, yarrow essential oil brought down anxiety levels and boosted mental and physical activity. While these findings are enticing, we need more research. We need to examine yarrow’s use in managing depression and anxiety further, especially in humans.
4. May Aid Brain Health
Different studies suggest that yarrow might be good for some brain disorders. These include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, and CNS inflammation.
- One animal study found yarrow extract brought down the severity of brain and spinal cord inflammation. It also guarded against it.
- Another study saw that yarrow’s antioxidants served anti-seizure effects. This suggests it might be used in seizure management.
- More animal research shows that yarrow might curb symptoms of Alzheimer’s and Parkinson’s diseases. These are memory loss and reduced physical movement.
These studies are limited to animals. We need more research on humans. That can prove these findings and set yarrow’s value for brain health.
5. May Fight Inflammation
Yarrow has many anti-inflammation substances. These may manage health problems linked to inflammation like arthritis, asthma, and skin problems.
- In animal studies, yarrow extract showed anti-inflammatory properties. It assisted in the natural recovery of irritated skin.
- Laboratory tests reveal yarrow extract may fight fever and liver inflammation. Both these are linked to inflammation.
Even though these studies suggest that yarrow has anti-inflammatory effects, more human research is needed. Only then we can verify its benefits.
Other Potential Uses and Benefits
Besides the above, yarrow has been historically used for other purposes. But for these, the scientific evidence is lacking or limited. Such uses include:
- Menstrual pain: Yarrow has a history of being used to relieve menstrual pain and heavy flow.
- Bleeding issues: The herb has been used to reduce heavy menstrual bleeding and improve circulation.
- Breathing issues: Yarrow’s antimicrobial and anti-inflammatory properties have been used to manage breathing infections and coughs.
- Sleep aid: Because it’s a mild sedative, yarrow tea or essential oils are believed to aid insomnia and anxiety.
As with its other potential benefits, we need more thorough research. Then we can confirm Yarrow’s effectiveness for these specific uses.
Precautions and Potential Concerns
Even though yarrow is seen as safe for most, we have some risks and precautions to consider.
1. Pregnancy and Lactation
Yarrow contains thujone. This could cause a miscarriage so do not take yarrow when pregnant. We lack enough data about its safety during breastfeeding. So, avoid this herb until after weaning.
2. Allergies
If you are allergic to plants in the Asteraceae family, you might also be allergic to yarrow, whether taken by mouth or applied to skin.
3. Epilepsy
Safety data on the usage of yarrow in epilepsy is lacking, so it is advised to avoid it in epileptic patients.
4. Drug Interactions
Yarrow might interact with some drugs, including:
- Blood-thinning drugs: High doses of yarrow might slow blood clotting. This raises the risk of bleeding with blood thinners like aspirin or warfarin.
- Lithium: Yarrow could raise lithium levels in the body. This might heighten the risk of toxic side effects.
5. Side Effects
The most common side effect of yarrow use is skin rash or inflammation. This is caused by an allergic reaction. Also, excessive amounts of yarrow might lead to blurry vision or dry mouth. This was seen in a case report where a woman drank five cups of yarrow tea per day for one week.
Like with any supplement, it’s important to discuss with your doctor before starting a regimen. This is crucial if you’re pregnant, breastfeeding, or on medication.
How to Add Yarrow to Your Diet?
You can get yarrow in different forms. That makes it easy for you to use based on your needs. These include loose leaves, essential oils, capsules, or tinctures.
Tea made from yarrow is popular. Just steep 1-2 teaspoons of dried yarrow leaves and flowers in hot water for 5-10 minutes. Buy dried yarrow or get ready-made tea bags from health stores or online.
Yarrow tinctures and extracts are concentrated form of the herb. It’s easier to control your dose and consistency with them. You can take these formulations by themselves or, mix them into water, juice, or smoothies.
Apply yarrow essential oils or ointments right onto your skin or, add them to baths, creams, or massage oils. First, do a patch test to be sure you don’t have an allergic reaction.
Remember to discuss with your doctor before adding yarrow to your diet or daily routine. Results vary between people.
Conclusion
Yarrow has a rich history as an ancient medicinal herb. It has many potential benefits, from wound repair and digestive relief to mental health. However, scientific evidence backing these claims is limited. We need more robust human trials to understand Yarrow’s real potential. Discuss with your healthcare professional before adding yarrow to your daily routine to ensure its usefulness for your needs. Be aware of potential risks and interactions.
