Yarrow is a perennial herb with finely divided feathery leaves and flat-topped clusters of small flowers. It contains a complex array of compounds including azulene (anti-inflammatory), achilleine (for blood clotting), sesquiterpene lactones, and flavonoids.

Traditional use

One of the oldest medicinal plants in the world—yarrow pollen was found in a Neanderthal burial site (60,000 years ago). Used in ancient Greece, Rome, and across Indigenous cultures worldwide for wound healing, fever, and menstrual regulation.

What modern research suggests (Traditional-only/Early)

Achilleine has demonstrated haemostatic (blood-clotting) activity. Anti-inflammatory and antimicrobial effects confirmed in vitro. Animal studies support antispasmodic effects on smooth muscle. Clinical trials are lacking—most evidence is mechanistic or traditional.

How people use it

As a fresh wound herb: press crushed fresh leaves against minor cuts and scrapes to slow bleeding. As a tea: steep 1–2 teaspoons in hot water 10 minutes for fever or digestive cramps. As a tincture: 1–4ml 3 times daily. For heavy periods: begin 1 week before menstruation.

Safety + interactions

Generally safe at food/medicinal doses. Avoid in pregnancy (may stimulate uterine contractions). Ragweed-sensitive individuals may react. May increase photosensitivity with prolonged topical use. Blood-thinning compounds—caution with anticoagulants.

May interact with: Blood thinners, Blood pressure medications, Sedatives

Name clarity note

Named after Achilles who reputedly used it on soldiers' wounds. Several Achillea species exist but Achillea millefolium is the primary medicinal species. Wild plants vary in chemistry by location—cultivated material is more consistent.

Quality notes

Look for yarrow with strong aromatic smell indicating essential oil content. Flowers should be white to pinkish. Standardisation is rarely done for yarrow—tincture or fresh plant preparations are preferred over capsules.
