As an astringent it is used for spider veins, varicose veins, and nose bleeds. The essential oil can be used topically for scars, stretch marks, and varicose veins.

Contraindications/Cautions:  may cause allergic reactions to those sensitive to Asteraceae plants. Some cases of hypersensitivity to yarrow have been reported.

Drug Interactions: Use with caution if you are taking oral contraceptives or any heart or blood pressure medications. 


  • Tincture: tincture of the fresh flowers and leaves can be kept on hand for first aid. Fresh tincture is also excellent for menstrual flooding and acts quickly, often in a formula with shepherds purse. Take 2-4ml of the tincture three times a day.
  • Infusion: pour a cup of boiling water onto l-2 teaspoonfuls of the dried herb and leave to infuse for l0-l5 minutes. This should be drunk hot three times a day. When feverish it should be drunk hourly.
  • Poultice: apply fresh leaves to wounds or hot tea compresses for bruises, sprains and strains.

Combinations: For fevers yarrow combines well with Elder Flower, Peppermint, Boneset and with Cayenne and Ginger. For raised blood pressure it may be used with Hawthorn, Linden Flowers and European Mistletoe.

Energetics:  harmonizing - yarrow can be either warming or cooling and is a prime example of an herb with dual energetics  due to its ability to move blood toward the skin or the core of the body as needed, thus regulating heat (Matthew Wood). While its diuretic and diaphoretic properties define it as drying, its ability to stop blood and astringe tissues can actually hold moisture in.

Folklore: Legend has it that Achilles himself used yarrow to heal the battle wounds of his comrades in the Trojan wars. Yarrow is also said to grow around the grave of Confucius. It is said the most effective way to cast the I Ching is by using yarrow straws, as the stems are good for divining the future. It was said that Druids used yarrow stems as a method of weather prediction. The Cherokee, Iroquois and Mohegan Native Americans used yarrow as a digestive aid and to treat a variety of types of swellings.

Homer tells the story of the centaur Chiron, a healer who conveyed herbal secrets to human students and is credited with teaching Achilles how to use yarrow on the battle field to both heal wounds and for its magical healing properties. When used by the goddess Aphrodite the plant becomes a loving herb used in love potions and to heal emotional wounds of the heart.

Flower Essence:  The spiritual and emotional essence of yarrow is one of protection, especially for the emotional field, for those who tend to have leaky energetic and emotional boundaries, and take on others emotions or feel drained by others emotional needs. Yarrow can be the healer of energetic emotional wounds that have left a lasting “energetic breach” where your emotional energy is “bleeding.” Several different kinds of yarrows are used to make the flower essences and have each particular benefits in addition to yarrow’s other protective qualities.. The flower essences also help protect from EMFs and other electromagnetic frequencies from radio, computers or TVs.

Applications:  It encourages blood to move out of where it pools or is stagnant, as well as moving fresh blood into areas that need improved circulation.  Women often use it to modulate heavy menstrual bleeding and support healthy circulation and move stagnation in the uterine tissue.   It is a prime remedy for colds and flus when there is a fever present. It stimulates the body to produce a healthy fever response, encourages sweating and combats infections internally as well.


Belgium Wild Beer Recipe


1 gallon water (3.75 L)
 0.2 ounce (2 g) wormwood
0.2 ounce (2 g) common yarrow
0.5 ounce (6 g) fresh ground ivy (creeping charlie)
0.3 ounces (4 g) chopped dried dandelion roots
3-4 crushed stems bitter dock 3 to 4 inches (7.5 to 10 cm) long or 1 to 2 lemons
1 1/4 pounds (680 g) brown sugar
Yeast (wild or commercial)


Place the sugar, wormwood, yarrow, dandelion roots and bitter dock stems into a large pot with water (cut and squeeze the lemons if you used them). Bring to a light boil for 30 minutes. Add the fresh ground ivy after 15 minutes of boiling.

Remove from heat and strain the brew into the fermenter then add the yeast. Position the airlock or cover your fermenter with a paper towel or cheesecloth. Let the beer ferment for 10 days. Start counting when the fermentation is active (may take 2 to 3 days with a wild yeast starter). Siphon into swing-top bottles (16 oz - 500ml) and prime them with ½ teaspoon (2g) brown sugar for carbonation. Close the bottles and store somewhere not too hot. The beer will be ready to drink in around 3 weeks.

Scientific Research

Achillea millefolium L. s.l. revisited: recent findings confirm the traditional use. Benedek B1, Kopp B.


Yarrow (Achillea millefolium L. s.l.) is traditionally used in the treatment of inflammatory and spasmodic gastro-intestinal disorders, hepato-biliary complaints and inflammation. Now we could show that the flavonoids mediated the antispasmodic properties of yarrow, whereas the dicaffeoylquinic acids caused the choleretic effects. Moreover, we observed an in vitro-inhibition of human neutrophil elastase, a protease involved in the inflammatory process, by extracts and fractions from yarrow, which suggests additional mechanisms of antiphlogistic action. The presented results confirm the traditional use of yarrow.

Minireview on Achillea millefolium Linn. Akram M.


Yarrow (Achillea millefolium L.) is an important medicinal plant with different pharmaceutical uses. A. millefolium has been used for centuries to treat various diseases including malaria, hepatitis and jaundice. A. millefolium is commonly prescribed to treat liver disorders. It is also used as an anti-inflammatory agent and is a hepatoprotective herb. A. millefolium is considered safe for supplemental use. It has antihepatotoxic effects also. It is prescribed as an astringent agent. It is prescribed in hemorrhoids, headache, bleeding disorders, bruises, cough, influenza, pneumonia, kidney stones, high blood pressure, menstrual disorders, fever, rheumatoid arthritis, gout, osteoarthritis, hemorrhagic disorders, chicken pox, cystitis, diabetes mellitus, indigestion, dyspepsia, eczema, psoriasis and boils

Radioprotective Effect of Achillea millefolium L Against Genotoxicity Induced by Ionizing Radiation in Human Normal Lymphocytes Somayeh Shahani1 , Mostafa Rostamnezhad2,3, Vahid Ghaffari-rad2,3, Arash Ghasemi4 , Tayyeb Allahverdi Pourfallah5 , and Seyed Jalal Hosseinimehr2


The radioprotective effect of Achillea millefolium L (ACM) extract was investigated against genotoxicity induced by ionizing radiation (IR) in human lymphocytes. Peripheral blood samples were collected from human volunteers and incubated with the methanolic extract of ACM at different concentrations (10, 50, 100, and 200 mg/mL) for 2 hours. At each dose point, the whole blood was exposed in vitro to 2.5 Gy of X-ray and then the lymphocytes were cultured with mitogenic stimulation to determine the micronuclei in cytokinesis-blocked binucleated cell. Antioxidant capacity of the extract was determined using free radicalscavenging method. The treatment of lymphocytes with the extract showed a significant decrease in the incidence of micronuclei binucleated cells, as compared with similarly irradiated lymphocytes without any extract treatment. The maximum protection and decrease in frequency of micronuclei were observed at 200 mg/mL of ACM extract which completely protected genotoxicity induced by IR in human lymphocytes. Achillea millefolium extract exhibited concentration-dependent radical-scavenging activity on 1,1-diphenyl-2-picryl hydrazyl free radicals. These data suggest that the methanolic extract of ACM may play an important role in the protection of normal tissues against genetic damage induced by IR.
