Yarrow! A Fascinating Plant!!

Pink yarrow plant

Yarrow is once again gracing my garden with her beautiful blooms. And so it’s time once again to harvest and tincture yarrow for her many healing qualities to have on hand when needed. And I love that it’s such an easy plant to grow and once started will continue to return each year with little fuss or care.

Yarrow, Achillea millefolium – Often touted as “the only herb you need” and “no herbal first aid kit is complete without it.”

The herb of many faces, yarrow is both a healer and a protector. While its clinical use is tried and true, the yarrow medicinal benefits extend far beyond the phytochemical realm. We look to its essence for strength, for guidance, and for creating a safe boundary to grow within.

Yarrow is named after the Greek hero Achilles, but the etymology is otherwise left to folklore. Some say when Achilles was dipped in the River Styx – everywhere but his heel which was laden with yarrow and the herb helped make him invincible. Others say that he used the plant to heal his soldiers in battle.

In any case, yarrow’s medicinal benefits are so profound they have been associated with the gods. That is something special, indeed!

What is Yarrow?

Yarrow is a perennial herb scientifically known as Achillea millefolium, and nearly every part of the plant is useful from a medicinal standpoint. Native to many areas in the Northern hemisphere, the use of this herb dates back thousands of years – even to ancient Greek legends. There are many common names for this herb, including old man’s pepper, the nosebleed plant, milfoil, soldier’s woundwort, and Thousand-seal, among others. Both the leaves and flowers of the yarrow plant are edible, as are the stalks, which can be crushed into a topical salve.

Yarrow leaves have a peculiar smell that is slightly spicy or peppery, particularly when they are crushed to release their aromatic compounds. Native Americans and ancient Britons used this herb extensively, and it is also present in Chinese traditional medicine, largely as an astringent substance. However, it remains one of the most versatile and recommended herbs in natural healing around the world.

This facilitates the coagulation of blood, which leads to the rapid closing of the wound. It also protects the wound from infections and numbs the pain. It was also used during wars to heal burn wounds that were caused by napalm. This is what gave it the title of “Herb of the Military”.

The Magic of Yarrow

Here’s the thing, it’s not just the yarrow medicinal benefits we’re here for. This beautiful plant’s use can be dated all the way back to the Druids, who used them as a strewing herb. They sprinkled yarrow in doorways to help protect against the evils, and used the stems to tell the coming weather – which is a truly lost art.

Throughout all of history, from its naming to its medicinal use, to the essence and magic, yarrow has been thought of as a very protective herb. Growing and strewing yarrow brings protection to the home, and hanging the stem and flower over a new marriage bed helps to create a bond – a single unit – for a long and solid relationship.

The flower essence of yarrow is used to help people create better boundaries. (Which is interesting that it’s used to help unify a marriage, yes?)

This plant and its essence are often included in a formula to help a person protect their own energy, find their space, and set healthy boundaries. Unlike some of the other boundary herbs, yarrow’s protection is gentle yet firm. It is a great plant to work with when one wants to set a gentle boundary with the outside world, while still allowing welcomed energies to pass through its veil.

A protector both energetically and physiologically, yarrow is one plant that any herbalist will want to include in their herbal apothecary and/or magical and essence kits!

How to Harvest Yarrow

As a garden herb, yarrow is super easy to grow and harvest. It’s pretty much a no-fuss, fool-proof herb for your garden. Allow the plant to grow to maturity. When the flowers open fully, harvest each stem with the head attached, all the way down to the ground. Hang the stems, with the flower head attached, upside down to dry for several days.

The leaves, stem and flowers contribute to the medicinal uses for yarrow. Every part can be used. Store the herb in an airtight container for up to one year.

If you wish to use the root of the yarrow plant, you should allow it to mature for at least 2 to 3 years before harvesting the entire root. Or you can take bits and pieces of the root each year. Dry the root out for a week before transferring it to an airtight container for up to a year.
