Find out how to use yarrow teas and tinctures to treat nose bleeds, menstrual issues, fevers, and more.
Yarrow (Achillea millefolium) or milfoil is a leading backyard medicine plant. A ready first-aid treatment for wounds and nosebleeds, it has larger uses as a circulatory system remedy that both stops bleeding and moves stagnant blood, preventing and clearing blood clots. It tones the blood vessels and lowers high blood pressure.
Yarrow is beneficial for a wide range of menstrual problems, and is a first-rate fever herb, used as a hot tea to induce sweating.
Yarrow is a famous wound and fever herb, yet today it can pass unnoticed except as a lawn weed. The legendary Achilles used yarrow as a field dressing for his soldiers’ wounds in the Trojan War, and the plant is named for him. A pity, then, he had none handy for his own fatal heel wound!
Asteraceae (Compositae) Daisy family
Description: A short perennial with feathery dark green leaves and flat heads of white or sometimes pink flowers.

Cautions: Yarrow can occasionally cause an allergic skin irritation. It is best not given to children under 5 years old, or taken by pregnant or breastfeeding women.
Medicinal Properties of Yarrow
Nosebleeds
Yarrow is our favorite remedy for nosebleeds, and it’s well worth keeping a patch by the back door if anyone in your family suffers from them. Simply pick a few fresh leaves — available year-round, though at their best in spring and the fall — and rub them between your hands to bruise them, releasing the aromatic oil. Roll the leaves into a nasal plug, insert into the affected nostril and leave until the bleeding completely stops before gently removing the plug.
Julie’s father suffered a really bad nosebleed once in the middle of the night, but luckily we had a patch of yarrow close by and the bleeding was soon stopped.
Yarrow has a traditional reputation of being able to start a nosebleed as well as stop one, from a time when bleeding was considered desirable as a cure for migraine. Indeed, one of the plant’s old names was “nosebleed.”
Hemorrhoids
It is certainly as effective at breaking up congealed blood as it is at stopping hemorrhages, making it a valuable first-aid remedy for thrombosis, for blood blisters and bruises with bleeding beneath the skin, as well as hemorrhoids. If treating for hemorrhoids, take yarrow tea or tincture internally, and place a yarrow poultice or compress over the affected area.
Menstruation
This special ability to both stop bleeding and break up stagnant blood makes yarrow a valuable menstrual remedy. It will correct both heavy and suppressed periods, and will normalize blood flow if there is clotting.
It is also a remedy for vaginal discharge and helps prevent painful periods. Austrian herbalist Maria Treben considered yarrow “first and foremost, an herb for women.”
On the Battlefield
This has truth, but the plant’s old names of soldier’s woundwort and knight’s milfoil bring us back once more to yarrow’s affinity for battlefields and for being a wound-packing material, probably long before the Achilles myth was recorded. Its use paralleled the development of weapons, and it was the herba militaris, the herb dressing carried by battle surgeons around the world until at least the American Civil War.
Yarrow has long had a particular repute for closing bleeding wounds caused by weapons or tools made of iron. In France it is called the herbe au charpentier (English version: carpenter’s grass) for the same reason. It is useful to know in case of domestic or outdoor accidents that yarrow’s emergency help can be at hand. Find a plant, strip the leaves, crush them and pack into the wound: it is antibacterial and antimicrobial so you will not introduce infection.
The reason why yarrow is so versatile — it was known as a “cure-all” herb — is that it works to tone the blood vessels, especially the smaller veins, and lower blood pressure by dilating the capillaries. This means it has a beneficial whole-body effect through the blood system, especially on conditions related to hypertension and including coronary thrombosis.
Reducing Fevers
But there is another range of bodily ills for which yarrow is well recommended, and this is in reducing fevers. By relaxing the skin, yarrow will open the pores to allow copious sweating and the release of toxins. Yarrow taken as tea (see below for a Yarrow Tea Recipe) or as a bath at the beginning of a fever or flu is an excellent way to reduce the body temperature. It is an herb for measles and chicken pox, and it is safe for children. It was once called “Englishman’s quinine” for a claimed benefit for treating ague (a form of malaria).
The sweating/purifying/relaxing effects are enhanced, herbalists have found, by combining equal quantities of yarrow, peppermint, and elderflower in a tea, drunk as hot and as often as the patient can stand. The same mix works well as a skin lotion or in a bath. The equivalent mixture for high blood pressure is yarrow plus nettle and lime blossom, again taken as a tea.
Other Beneficial Uses of Yarrow
Yarrow has various other health benefits, as befits its all-rounder status. Its effect on bodily fluids helps in cases of diarrhea and dysentery. It is effective for colic and blockages of the urogenital area, as also for stomach cramps, cystitis, arthritis, and rheumatism.
A yarrow lotion makes a good eyebath and stimulates the scalp, with traditional benefit to the hair; plugs of crushed leaves help to relieve toothache or earache.
Yarrow Through History
Yarrow has a further dimension to its long human history: it is an herb of divination, used by the Druids for predicting the weather, by the Chinese for auguries (in the Book of Changes or I Ching), and by love-lorn English maidens for indicating who their true love would be. One chant from East Anglia links the yarrow of blood and the yarrow of foretelling:
Yarroway, yarroway, bear a white blow
If my love love me, my nose will bleed now.
Yarrow’s Shadow Side
These were benign uses, but the past is not one-sided and yarrow also had a shadow side, being called the “devil’s nettle” and “bad man’s plaything.” For the most part it was involved in sympathetic magic, as in its part in St John’s day celebrations.
All this virtue, and a little vice, comes with a tally of yarrow’s profit and loss account. No question, it is one of the great presences in western herbalism. At the same time, some cautions should be noted.
Cautions
Yarrow has a stimulating effect on uterine contractions, so is best avoided in pregnancy; prolonged use externally can, in some people, cause allergic rashes and make the skin ultra-sensitive to sunlight; large doses can cause headaches.
You should also be aware that the active constituents of yarrow vary from plant to plant and by locality. If you try yarrow for any of the uses we have outlined and it seems to be ineffective, go to another plant and use that.
How to Harvest Yarrow
Yarrow leaves are evergreen so can be harvested fresh almost whenever they are needed. To make a tincture or when drying for tea, it is best gathered while flowering. Yarrow accumulates particulates from vehicle exhausts because of the large surface area of its flowerhead and leaves, so it is best to pick it away from busy roads.
To dry your yarrow, hang whole stems in bunches or place them on brown paper in a warm dry place. Allow a month, and once they are dry, strip the leaves and flowers off the stems and crumble for use as a tea. Smaller stems can be chopped up with scissors, but the larger stems are usually discarded. Keep the leaves dry and you can use them for months, or find fresh leaves for a green tea.
How to Make Yarrow Tea
Use 1 heaped teaspoonful of dried yarrow per cup or mug of boiling water, and let it infuse for 10 minutes. Strain and drink hot.
Dose: For colds and feverish conditions, drink a cupful hot every two hours until there is an improvement, and continue drinking three cups a day until you are well. For chronic conditions, drink three cups a day. For fevers, yarrow combines well with mint and elderflower. Use externally as a wash for cuts, and as a hair rinse for a healthy scalp and shiny hair.
Use yarrow tea for:
• Colds and fevers
• Scanty menstruation
• Heavy periods
• Menstrual clotting
• High blood pressure
• To tone varicose veins
• To prevent blood clots
• Tension
• Weak digestion
Yarrow Tincture
Chop up fresh yarrow leaves and flowers, and put in a jar. Pour in enough vodka to cover, put the lid on, and place the jar in a dark cupboard for two weeks. Shake it every few days. Strain and bottle.
Dose: 20 drops in water, three times a day.

Ointment for Hemorrhoids
Gently heat 1 oz dried yarrow and 1 oz dried raspberry leaf or 1 oz horse chestnut leaf with 1 cup extra virgin olive oil in a small saucepan for 15 minutes, stirring frequently. Strain out the herbs and return the oil to the pan. Add about 1 oz beeswax and stir until melted. Use enough beeswax to set the ointment — test a few drops on a cold saucer as you do when making jelly. If you live in a hot climate or it is summer, you will want to use more beeswax than if the weather is cold. If your ointment is too runny, you can melt it again and add more beeswax.
Apply the ointment externally a couple of times a day as needed. It can also be used on bruises, varicose veins, and thread veins.
