Yarrow for Menorrhagia: Does It Work?
Does Yarrow (Achillea millefolium) help with menorrhagia, the heavy menstrual bleeding Ayurveda calls (Asrigdara)? In Ayurvedic herbal practice, yes. Yarrow is described as reducing excessive menstrual bleeding and helping to stop menstrual cramps, and menorrhagia is on its list of indications.
The fit comes from its properties. Yarrow tastes bitter, astringent, and pungent, has a cooling potency (Sheeta Virya), and a pungent post-digestive effect (Katu Vipaka). It calms Pitta and Kapha, though it can raise Vata in excess. Since Ayurveda reads most heavy periods as Pitta overheating the blood, a cooling, astringent herb that stops bleeding is a sensible match.
It helps to set expectations. Yarrow's action is described as mild, mainly treating more superficial conditions. That makes it a gentle supporting herb for heavy periods rather than a strong uterine remedy, well suited to milder Pitta-type bleeding with cramping.
How Yarrow Helps with Menorrhagia
Yarrow addresses heavy bleeding through three actions that work together: cooling, stopping bleeding, and easing spasm.
Cooling Pitta
Yarrow is described as a versatile herb for Pitta conditions. In the Pitta pattern of menorrhagia, Pitta builds up in the blood tissue (Rakta Dhatu), overheats it, and flow turns bright, hot, and heavy. Yarrow's cooling potency and bitter taste counter that heat. It works on the plasma, blood, and muscle tissues through the circulatory system.
Astringent and hemostatic
Yarrow is both astringent and hemostatic. It is said to stop bleeding both internally and externally, which is why nosebleeds, coughing up blood, and stomach ulcers sit on its list alongside heavy periods.
Antispasmodic for cramping
Yarrow is also antispasmodic and specifically helps stop menstrual cramps. Many heavy periods come with cramping, especially when Vata is involved alongside Pitta, so this second action makes yarrow more useful than a pure astringent.
The caution is Vata. Yarrow can aggravate Vata in excess and should be used carefully in high Vata conditions, so it is less suited to the dark, erratic, Vata-dominant pattern.
How to Use Yarrow for Menorrhagia
For heavy periods, yarrow is used in its classical forms: a hot or cold infusion, a powder, or a paste for external use.
Best form for menorrhagia
A cold infusion suits the hot Pitta pattern best, since it keeps the preparation as cooling as possible. A hot infusion is a gentler choice when cramping is the main complaint, because warmth supports its antispasmodic action.
| Form | Dose | Best for |
|---|---|---|
| Cold infusion | Dried herb steeped in room-temperature water | Pitta pattern: bright red, hot flow |
| Hot infusion | Dried herb steeped in just-boiled water | Heavy flow with cramping |
| Powder | 250 to 500 mg | When an infusion is impractical |
Who it suits
Yarrow fits the Pitta and Kapha patterns of heavy bleeding. Because its action is mild, it works best for moderate heavy flow rather than severe bleeding. Use it with caution if Vata is high, for example if your flow is dark and erratic or you tend toward dryness and anxiety.
Frequently Asked Questions
How strong is yarrow for heavy periods?
Mild. Yarrow's action is described as gentle and mainly suited to more superficial conditions. It is a good supporting herb for moderate Pitta-type heavy flow, not a remedy for severe bleeding.
Does yarrow help with period cramps too?
Yes. Yarrow is antispasmodic and is specifically described as helping to stop menstrual cramps, as well as reducing excessive bleeding.
Who should be careful with yarrow?
People with high Vata. Yarrow can aggravate Vata in excess, so if your heavy periods are dark, erratic, and come with dryness or anxiety, use it cautiously or choose a different herb.
Yarrow vs Red Raspberry or Horsetail for menorrhagia?
Red Raspberry has a closer affinity with the uterus and also tones it. Horsetail adds blood cleansing and diuresis. Yarrow's advantage is that it cools, stops bleeding, and eases cramps in one gentle herb.

Safety: Use yarrow with caution if Vata is high. Soaking a pad every hour, large clots, periods beyond seven days, or dizziness need a doctor first.
Safety & Precautions
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.
