What is Yarrow?
If you have ever reached for something cooling during a hot, feverish cold, or wished for a gentle plant ally for heavy periods or a nosebleed, Yarrow deserves a look. It is a European meadow herb, not a classical Indian one, yet modern Ayurvedic practice has adopted it because its property profile fits Ayurvedic thinking so neatly.
Botanically it is Achillea millefolium, a member of the Compositae (daisy) family. The genus name points back to Achilles, who in legend used the plant to staunch bleeding wounds on the battlefield. That old story still sums up its reputation: a herb that cools heat and stops bleeding.
In Ayurvedic terms, Yarrow tastes bitter (Tikta), astringent (Kashaya) and pungent (Katu). It has a cooling potency (Sheeta Virya), meaning its overall effect on the body is to cool, and a pungent post-digestive effect (Katu Vipaka), the lasting effect it leaves after digestion. It calms Pitta and Kapha but can aggravate Vata when overused.
Yarrow works on the plasma, blood and muscle tissues and acts on the circulatory, respiratory and digestive systems. Its action is described as mild, best suited to more superficial conditions rather than deep, long-standing disease.
Benefits of Yarrow
Yarrow's benefits all flow from one combination: it cools, it dries and tones tissue, and it stops bleeding. Its named actions are astringent, antispasmodic, haemostatic (stops bleeding), vulnerary (wound-healing) and diaphoretic (promotes sweating). Here is how those play out.
Fevers, Colds and Flu
Yarrow is a cooling diaphoretic and febrifuge, meaning it opens the pores to encourage a sweat and helps bring a fever (Jwara) down. It is described as particularly good for colds, flu and infectious diseases where fever and inflammation run high.
The reasoning is Ayurvedic: the pungent taste opens the channels to release heat through sweat, while the cooling potency and bitter taste calm the Pitta heat behind the fever. Measles is also on its traditional list of indications.
Bleeding, Inside and Out
Yarrow is said to stop bleeding both internally and externally. Its indications include nosebleed (Nasagata Raktapitta), coughing up blood (hemoptysis) and bleeding stomach ulcers.
Ayurveda reads much bleeding as Pitta overheating the blood tissue (Rakta Dhatu). A herb that is cooling and astringent at once is the classic answer to that pattern, which is why Yarrow fits.
Heavy Periods and Cramps
Yarrow is described as reducing excessive menstrual bleeding and helping to stop menstrual cramps. Menorrhagia (Asrigdara), the Ayurvedic name for heavy menstrual bleeding, is on its list of indications.
The astringent, haemostatic action addresses the flow, while the antispasmodic action eases cramping. Because its action is mild, it suits moderate Pitta-type heavy flow rather than severe bleeding.
Digestive Inflammation
Gastritis, enteritis and stomach ulcers appear among Yarrow's indications. These are hot, inflamed conditions of the digestive tract, and Yarrow's bitter, cooling and astringent qualities are a natural match for calming that Pitta heat.
Wounds and Abscesses
As a vulnerary herb, Yarrow has a long reputation for wound care, and abscesses are among its listed uses. A paste is the traditional external form.
How to Use Yarrow
Yarrow is used in three main forms: an infusion (hot or cold), a powder, or a paste for external use. The infusion is the standard everyday form, and the temperature you choose changes how it works.
| Form | Dose | Best For | When to Take |
|---|---|---|---|
| Cold infusion | 120-240 ml, twice daily | Pitta heat, bleeding tendency, heavy periods | Between meals |
| Hot infusion | 120-240 ml, up to three times daily | Fever, colds and flu, menstrual cramps | Through the day during illness |
| Powder | 250-500 mg, twice daily | A concentrated daily course | Before meals |
| Paste (external) | Thin layer | Wounds, abscesses, a cool compress | As needed |
Hot or Cold?
A hot infusion leans into Yarrow's diaphoretic side, encouraging a sweat during a fever, and its warmth supports the antispasmodic action for cramps. A cold infusion keeps the preparation as cooling as possible, which suits hot, Pitta-type bleeding.
What to Take It With
The vehicle you take a herb with is called anupana. For Yarrow powder, cool water or honey is traditional. If you run dry or Vata-prone, a little ghee helps soften Yarrow's drying tendency.
Safety & Side Effects
Yarrow is a mild herb, and for most people its main caution is simple: it can aggravate Vata in excess. Its bitter, astringent and pungent tastes are drying, so use it carefully if you have a dry, high-Vata constitution or a Vata condition.
Who Should Avoid It
- Pregnancy: avoid Yarrow. It has mild emmenagogue (menstruation-promoting) and uterotonic effects.
- Daisy-family allergy: Yarrow belongs to the Compositae family. Do not use it if you are allergic to ragweed, chamomile or related plants.
- Before surgery: stop at least two weeks before planned surgery, because its haemostatic action can affect bleeding-time tests.
Medications
If you take warfarin, clopidogrel, aspirin or any other blood-thinning medication, talk to your prescribing clinician before using Yarrow daily.
Know Its Limits
Yarrow's action is mild and mainly treats superficial conditions. Severe, heavy or recurrent bleeding, and any fever that will not settle, need proper medical evaluation. Yarrow is a supporting herb, not a substitute for that.
Recommended: Start Here
The simplest way to start with Yarrow is a plain infusion of the dried herb. It is the most traditional form, it is gentle, and you can adjust it to what you need just by changing the water temperature.
Your Starting Point
For a feverish cold or flu, or for period cramps, make a hot infusion: pour just-boiled water over the dried herb, steep, strain and sip warm. For hot, Pitta-type complaints such as heavy flow or a tendency to nosebleeds, make a cold infusion by steeping the herb in room-temperature water instead.
Take 120-240 ml once or twice a day and see how you respond. If you tend toward dryness, a little ghee alongside offsets Yarrow's drying quality.

Safety: avoid Yarrow in pregnancy and if you are allergic to daisy-family plants such as ragweed or chamomile, and use it cautiously if Vata is high.
Yarrow vs Other Herbs & Supplements
Yarrow is usually compared with other cooling, bleeding-stopping herbs. Here is how it stacks up against the ones Ayurvedic practitioners most often weigh it against.
| Comparison | Yarrow | Alternative | Verdict |
|---|---|---|---|
| Yarrow vs Durva Grass | Cooling, astringent, haemostatic and also fever-reducing; drier, can aggravate Vata | Durva: cooling, astringent, haemostatic; the classical Indian first choice for nosebleed, named in the Bhavaprakash as a remedy for bleeding disorders (Raktapittahara) | Choose Durva for straightforward bleeding and gentler use. Choose Yarrow when fever, infection or heavy periods are part of the picture. |
| Yarrow vs Manjishtha | Faster acting, suited to short courses and topical use | Manjishtha: another reliable Pitta-cooling herb for bleeding, slower acting than Yarrow | Yarrow for acute, feverish or inflamed episodes; Manjishtha when there is no fever or acute flare. |
| Yarrow vs Red Raspberry | Cools, stops bleeding and eases cramps in one herb | Red Raspberry: closer affinity with the uterus, which it also tones | For heavy periods with cramping, Yarrow covers more ground; for uterine toning, Red Raspberry. |
| Yarrow vs Horsetail | Astringent, haemostatic and antispasmodic | Horsetail: adds blood cleansing and diuresis | Yarrow when cramps accompany heavy flow; Horsetail when fluid and blood cleansing matter more. |
Yarrow for Specific Populations
Pregnancy & Nursing
Avoid Yarrow during pregnancy. It has mild emmenagogue (menstruation-promoting) and uterotonic effects, so it is not appropriate from conception through delivery, even for problems like nosebleed where it would otherwise fit. The sources we draw on do not address breastfeeding, so check with a qualified practitioner before using it while nursing.
Children
Classical and practitioner sources do not set a children's dose for Yarrow. External folk uses, such as fresh leaf for a nosebleed, should only be done with adult supervision. For internal use in children, ask a qualified practitioner first.
Elderly
Our sources give no specific guidance for older adults. The general rule applies: Yarrow's drying quality can aggravate Vata, so anyone with a dry constitution should use it cautiously and in short courses, ideally with practitioner input if other medicines are involved, particularly blood thinners.
Athletes
Yarrow has no specific sports use in the sources. Its traditional role as a vulnerary (wound-healing) herb, applied as a paste to minor wounds, is the closest practical fit for active people.
Frequently Asked Questions
Is Yarrow a traditional Ayurvedic herb?
Not originally. Yarrow is a European herb that modern Ayurvedic practice has adopted because its profile maps cleanly onto Ayurvedic categories: bitter, astringent and pungent in taste, cooling in potency, and calming for Pitta and Kapha. In other words, it is a modern adoption rather than a herb of the classical Indian texts.
Which dosha does Yarrow suit best?
Pitta, and to a lesser extent Kapha. It is described as a versatile herb for Pitta conditions, especially those with heat, inflammation or bleeding. People with high Vata should use it cautiously because it can aggravate Vata in excess.
Why does Yarrow make you sweat?
Yarrow is a diaphoretic, meaning it promotes sweating. Taken as a hot infusion during a fever, this helps release heat from the body, which is why it is traditionally used for colds and flu where fever runs high.
How strong is Yarrow?
Mild. Its action is described as gentle and mainly suited to superficial conditions. That makes it a good supporting herb for everyday fevers, minor bleeding and moderate heavy periods, but not a remedy for serious or deep-seated illness.
Can Yarrow be used on the skin?
Yes. Yarrow is a vulnerary (wound-healing) herb and is traditionally applied as a paste for wounds and abscesses. It is also said to stop bleeding externally. Skip it if you are allergic to daisy-family plants.
