Yarrow grows just about everywhere in the summertime, and it’s an easy to forage herb that’s the perfect addition to natural facial soap.
Yarrow is one of my favorite herbs to spot in the summertime. As a young herbalist, I remember reading about all the wonderful things this herb could do, but I happened to be growing up in the Mojave desert, one of the few places in the US where yarrow doesn’t grow. I couldn’t wait to find it, this herb that grows like a weed everywhere…or everywhere except where I lived.
Now that I live in Vermont, I can truly appreciate how common yarrow is in the wild, but I still get excited whenever I see a patch. (Here’s how to identify yarrow in the wild.) Anything yarrow makes my heart start to flutter a bit, remembering back to my young self and the passion I had for this particular plant in my youth.
When I saw this recipe for yarrow and witch hazel soap in the Nerdy Farm Wife’s Natural Facial Soaps book I sent her a note and asked permission to reprint it. Just one more way to spread the yarrow love!
(If you’re a first-time soap maker, I recommend reading this primer on how to make soap before you get started.)
Benefits of Yarrow Soap
Witch hazel is a natural astringent, and it’s commonly used to treat acne, but what about yarrow? Why would you put yarrow in a homemade soap?
According to Learning Herbs, it’s one of the 10 best herbs to use in soaps. They note that “While yarrow is often used internally, it is also used topically to fight against inflammation and help heal wounds faster due to its antibacterial and antiseptic properties. This makes it great for acne, eczema, and other skin conditions. Yarrow has tiny white flowers that can be dried and used on top or within soap. Leaves and flowers can be used in an herbal oil infusion and/or tea for the lye water in your soap recipe.”
This recipe, in particular, has you make a yarrow tea before you start, and that yarrow tea is added as part of the lye/water solution. You can also infuse the yarrow into the liquid oils in this recipe, straining it out before making the soap.
It takes a few weeks for yarrow to infuse into oils, so making a tea is a quicker method. The tea method also works well with either dried or fresh yarrow, while the infused oil method is best made with dried yarrow.
Wild Foraged Soapmaking Resources
Jan has a number of different soapmaking books, which walk you through everything you need to know to get started. I particularly love how she incorporates wild ingredients into her natural soaps, allowing you to bring nature into your home in yet another place…the shower.
Her natural soapmaking ebook collection even includes a recipe for mushroom soap. I think it’d be lovely with some of our homegrown shiitake mushrooms, or maybe better yet, a few wild foraged reishi mushrooms.
If you’re confused about where to start, you can also read her Soapmaking 101 article for pointers.

Oils & Butters
- 13.5 oz (383 g) olive oil
- 6.5 oz (184 g) babassu oil
- 3.5 oz (99 g) safflower oil
- 2.5 oz (71 g) hemp oil
- 2 oz (57 g) castor oil
- 3.84 oz (109 g) sodium hydroxide (NaOH)
- 7.25 oz (206 g) chilled yarrow tea
- Digital Scale
- Plastic Bowls and Utensils
- Soap Mold for Shaping
To make the yarrow tea place 1⁄4 cup dried yarrow (or 1⁄2 cup fresh yarrow) in a jar, pour 1 cup simmering water over. Steep 30 minutes to 1 hour, strain and then chill completely before using in recipe.
Put on protective clothing, eyewear and gloves before carefully stirring lye into the yarrow tea until dissolved. Set the solution aside to cool to between 100 and 110 degrees.
While the lye solution cools, gently warm the oils to around 100 to 110 degrees so that the two mixtures are close in temperature.
When both solutions are between 100 and 110 degrees. Pour the cooled lye solution into the warmed oils. Use an immersion blender to stir the batter until it thickens or achieves "trace." This is when soap dripped back into the pot leaves a visible "trace" on the surface.
Blend the witch hazel into the soap once you reach light trace. Be sure that it’s blended in well, to avoid separation.
Pour the soap batter into a prepared mold and cure the soap for a few days until it can be easily removed from the mold. Slice the soap and cure for about 4 weeks to allow extra moisture to evaporate out before using.
Safflower oil can be substituted with sunflower, hazelnut or walnut oil, while hemp oil can be replaced with grape seed oil.
Coconut oil can replace babassu oil, with a slight lye adjustment to 3.89 oz (110 g).
