Achillea millefolium

Also calledBiranjasif (Unani) · Gemeine Schafgarbe (German) · Milenrama (Spanish) · Shī 蓍 (Chinese, yarrow) · Soldier's woundwort (English) · Nosebleed (English folk)

A feathery-leaved perennial of meadows and roadsides found across most of the Northern Hemisphere, named for Achilles, who by legend used it to stop his soldiers' bleeding. Its flat-topped white flower clusters are visited by hundreds of insect species.

Achillea millefolium, commonly known as yarrow or common yarrow, is a flowering plant in the family Asteraceae. Growing to 1 metre tall, it is characterized by small whitish flowers, a tall stem of fernlike leaves, and a pungent odor. Wikipedia

§1

What it can do

  1. iContains achilleine and tannins traditionally used to slow bleeding from small wounds
  2. iiFeathery, finely divided leaves ("millefolium" = thousand-leaved) reduce water loss in dry sites
  3. iiiSpreads by rhizomes to form drought-tolerant mats, used in lawns and erosion control
  4. ivFlat-topped flower clusters (corymbs) feed a broad range of hoverflies, small bees and parasitoid wasps that control garden pests
  5. vGrows from sea level to above 3,500 m in the Rockies and Himalaya

Eatenyoung leaves (sparingly) · flowers (tea)

Young leaves are bitter and used in small amounts as a herb; historically used to bitter beer. Contains thujone in some chemotypes. Avoid in pregnancy. Can be confused with poisonous Apiaceae such as poison hemlock by beginners; check the leaves carefully.

Weight of evidence

Traditional. Long historical use; little or no modern clinical evidence.

Soil
Any well-drained soil; thrives in poor, dry ground
Propagation
Seed or division in spring or autumn
To harvest
Flowers the second summer from seed, or the first from divisions
Climates
Temperate, Continental, Mediterranean, Alpine
  1. 1Surface-sow in spring or plant divisions about 30 cm apart
  2. 2Water until established, then leave dry; rich soil makes it floppy
  3. 3Cut flowering stems when the clusters are fully open and hang to dry
  4. 4Divide every few years to control spreading

§9

Marginalia

Pliny the Elder records that Achilles used the plant on wounds, which gave the genus its name. In China, dried yarrow stalks were the traditional tool for casting I Ching hexagrams.

Curiosity

The classical I Ching divination used 50 yarrow stalks, sorted by hand over and over to build each six-line hexagram.
