You know, I never really connected with yarrow. I know it’s kind of a magical herb staple, but I was always more into mugwort and its ilk. For some reason, yarrow just didn’t quite grab me the way that certain other herbs did.
All of that aside, I have lots of it now. When I embarked on my crusade to murder the grass and replace it with useful things (my rules are that they must either feed me or the local fauna, and preferably both), yarrow was a natural fit. It’s a lovely plant that gets tall enough to fill the space in my flower beds, and it’s very aromatic. Working with it in a gardening capacity has given me a new appreciation for it as a magical and medicinal herb, and the bees really seem to enjoy it.
Yarrow Folklore and Magical Uses
Yarrow is one of the oldest medicinal herbs. Like, pre-pre-history old. Archaeologists have identified yarrow among the belongings of a 65,000 year old Neanderthal.
Achillea specimens are found pretty much everywhere, with the exception of Africa and Antarctica. There are Achillea millefolium subspecies found in Europe, Asia, the Arctic, the Himalayas, the Alps, the Carpathians, the western US, Alaska, the US in general, and one particular that’s endemic solely to California. It’s probably not surprising that it’s often considered an aggressive weed, and may be best confined to areas that you either don’t mind having it take over, or allow you to control its spread.
Interestingly, all of these subspecies seem to have different medicinal effects. There’s some overlap, of course, but each subspecies appears to have different ratios of medicinal compounds.
The genus Achillea is named for the Greek hero Achilles. Chiron taught him the plant’s medicinal properties (specifically using it to treat wounds — hence its other common name, woundwort) and carried it into battle. It’s anti-inflammatory and antibacterial, so it’s a good plant to reach for to treat minor cuts, scrapes, and bruises.

This connection with battle may be why yarrow is also used as an herb for courage.
Yarrow is a protective and purifying herb. Like many herbs used to cleanse and protect, this action is borne out by its ability to repel pests. Experiments with birds using yarrow as a nest lining found that it inhibits the growth of parasites. The connection between repelling pests and magical protection is seen pretty often, as with pennyroyal, or fennel, for example.
In Europe, scattering yarrow across the threshold of a home was believed to keep evil from entering.
Yarrow is historically a divination herb. In China, one way to cast the I Ching involved counting stalks of yarrow. In Europe, it was used for love divination. You’d take a yarrow leaf and stick it up your nose, tickling yourself with it as you said,
Yarroway, yarroway
Bear a white blow.
If my love love me,
Let my nose bleed now.”
Traditional
Another method for love-divination involved placing yarrow under your pillow. If you dreamt of your love, it was a positive omen. If you had a bad dream, or dreamt of other people, it wasn’t.
An old Gaelic incantation for yarrow-picking went thus:
I pluck the smooth yarrow,
That my finger be sweeter,
That my lips be warmer,
That my voice be gladder.”
Yarrow was said to be a sacred plant to the ancient Druids, used for weather divination.
In the Victorian language of flowers, yarrow represented everlasting love.
Yarrow is connected to Venus and the element of Water.
Using Yarrow
Since so many practitioners of witchcraft and Druidry have pets and small children, I probably wouldn’t recommend just strewing your threshold with yarrow. Instead, scatter some of the dried herb under your front doormat, where curious hands or snouts can’t get into it. You can also grow yarrow near your front door — it’ll feed your local pollinators and help keep evil away.
Yarrow hydrosol is another useful way to work with this herb. It’s good for your skin. (For real, an ointment containing yarrow was researched for its ability to help heal episiotomies. Ouch!) It can also have a purifying effect, so it’s a nice way to prepare yourself for rituals. The leaves and hydrosol are also fragrant, so the scent is a nice for getting into a magical mindset.
For divination, you could either learn to cast the I Ching with traditional yarrow stalks, or include it in a spray or sachet to use while reading tarot, runes, or Ogham staves. Including it in a dream pillow is said to lead to prophetic dreams.

As a Venus-ruled herb, it’s also a good choice to include in love jars or sachets. Traditionally, its power was to help the user find their true love, and keep lovers together. That makes it a worthwhile addition to spell to draw in true love and help it last.
Medicinally, yarrow hydrosols, infusions, and ointments are great for topical conditions like stings, bug bites, scrapes, burns, scratches, cuts, and bruises. (Never put anything ointment-y over deep wounds, puncture wounds, or animal bites, however.) Teabags or poultices of yarrow are also nice for easing sore eyes — just be careful not to get yarrow in them! If you’re allergic to yarrow or other members of the Asteraceae family, skip yarrow and use something else.
This herb is also used for treating a ton of internal conditions, from digestive trouble to colds and flu. But, like I mentioned previously, each subspecies seems to have its specialties. Before using yarrow internally, you should consult with a qualified herbal practitioner to choose the safest and most effective herbs for your condition.
