Why has this wild late-summer herb been associated with dreams for centuries - and can we turn that old relationship into something meaningful for a modern home apothecary?
I harvested mugwort because I wanted to explore why this plant has been associated with dreams for centuries - and it turns out drinking it isn't the only way people have worked with it.
In fact, the deeper I looked, the more interesting mugwort became. Because Artemisia vulgaris isn't a rare medicinal plant hidden away in some inaccessible landscape. It grows abundantly around us here in Britain: along footpaths and field edges, on disturbed ground, beside roads and tucked into the untidy places between cultivated land and the wild.
It is remarkably easy to walk straight past.
But turn over one of its deeply divided leaves and you'll find the soft, silvery-white underside that makes mugwort so distinctive. Crush a leaf between your fingers and there is another clue: an unmistakably aromatic, slightly bitter, herbaceous scent.
And for a plant that can appear so ordinary, mugwort has accumulated an extraordinary amount of folklore.
Protection. Travel. Women's health. Divination. The threshold between waking and sleeping.
And, perhaps most famously today, dreams.
So I wanted to know where that association actually came from.
Was mugwort really used as a “dream herb” in the way we so often hear today? What did earlier herbalists actually use it for? And is there a thoughtful way to explore its relationship with sleep and dreaming now, while respecting the difference between traditional knowledge and what modern science can demonstrate?
That question eventually led me to a little jar of mugwort dream balm.
But first, we need to meet the plant.
Meet Mugwort: Artemisia vulgaris
Mugwort belongs to the Asteraceae family, alongside plants including chamomile, yarrow, dandelion and calendula.
It is an abundant perennial found across much of Europe, often growing on disturbed ground, field margins, waysides and the slightly untidy edges of the landscape.
It can reach well over a metre tall (particularly later in the summer), with reddish ribbed stems and deeply divided leaves. The upper surface of the leaf is green, but turn it over and you'll find the soft silvery-white underside that makes mugwort much easier to recognise. Its small flower heads appear in branching clusters rather than producing the showy flowers we might associate with some of its botanical relatives.
By late summer, mature mugwort can be wonderfully aromatic - green, bitter and slightly camphoraceous. It is this aromatic quality that gives us our first clue that there is more going on chemically than its rather unassuming appearance suggests.
The leaves and flowering tops are the parts traditionally used, and I was particularly pleased to discover that the timing of my own harvest was rather good. Mugwort becomes increasingly woody as the season progresses, and the source I was reading recommends gathering the flowering tops as they begin to flower (typically during July-August), when the concentration of volatile oil is higher.
Even its botanical name carries an intriguing story. Artemisia has long been associated with Artemis, the Greek goddess of wilderness, childbirth and later the Moon - although the true origin of the name is uncertain, and Artemisia II of Caria has also been proposed. Either way, it's an intriguing association for a plant that would become so deeply entwined with women's health, folklore and, eventually, dreams.
The Oldest of Herbs
Mugwort's place in British herbal history stretches back a very long way.
One of my favourite references appears in the Nine Herbs Charm, an Old English healing charm preserved in the Lacnunga, a collection of remedies, prayers and charms surviving in a manuscript written around the end of the Anglo-Saxon period.
And mugwort comes first.
It is addressed directly as mucgwyrt and described as “the oldest of herbs.”
I love this because it gives us a glimpse of something that can be easy to lose when we reduce medicinal plants to lists of actions and indications. Plants weren't always understood simply as collections of active constituents. They were observed, named, carried, prepared, spoken about and woven into people's understanding of health and the natural world.
The Nine Herbs Charm itself combines plants with ritual language and elements of both pre-Christian and Christian belief. Mugwort appears alongside plants including plantain, nettle, chamomile, crab apple and fennel.
It doesn't prove anything pharmacologically about mugwort.
But it does tell us something important: People living on this landscape were paying attention to this plant more than a thousand years ago.
And mugwort's reputation didn't disappear with the Anglo-Saxons.
A Herb for Travellers, Thresholds and Protection
One of the recurring themes surrounding mugwort in European herbal tradition is travel.
Historical sources describe it being carried on long journeys, particularly in traditions concerned with fatigue and protection while travelling. Mugwort and sage were carried to prevent tiredness, while the medieval Physicians of Myddfai recorded a preparation of mugwort and garlic taken before setting out on a journey to protect against both hurt and fatigue.
Its protective reputation extended beyond travel, too. Mugwort was worn as a charm against harm and the evil eye, and garlands of the herb were traditionally worn on St John's Eve before being cast into the midsummer fire - symbolically casting off misfortune with them.
Of course, these are traditions rather than evidence of therapeutic effect. But I find the symbolism interesting.
Mugwort repeatedly appears at thresholds.
Journeys from one place to another.
Protection while moving through unfamiliar territory.
Midsummer traditions.
Women's reproductive transitions.
And, eventually, the strange nightly threshold between waking consciousness and sleep.
Perhaps it isn't surprising that a plant already surrounded by ideas of crossing boundaries eventually became entwined with dreaming.
But here we encounter an important problem.
Was Mugwort Really Traditionally Used for Dreams?
Search for mugwort today and you will quickly find claims that it has been used for lucid dreaming for thousands of years, increases REM sleep or that its thujone content produces vivid dreams.
The historical picture is much less tidy.
There is later folklore connecting mugwort with dreams, divination and altered perception, but tracing a continuous ancient tradition of using it specifically to induce lucid dreams is surprisingly difficult.
What we can find is an intriguing historical connection with sleep. The 17th-century botanist Caspar Bauhin included inducing sleep among the uses of mugwort in his day.
That doesn't mean mugwort causes vivid or lucid dreams - and we don't currently have good clinical evidence showing that it does. But that doesn't make the tradition meaningless.
Tradition and folklore are one kind of knowledge. Personal experience is another. Pharmacological evidence is another.
Part of working thoughtfully with medicinal plants is allowing those things to sit alongside one another without forcing them to say the same thing.
What Might the Chemistry Tell Us?
Crush mugwort between your fingers and its aromatic nature is immediately apparent, but analysis shows that the chemistry behind that aroma can be remarkably variable.
Analysis of Artemisia vulgaris volatile oil has identified compounds including 1,8-cineole, camphor, sabinene, germacrene D and thujones - but the proportions vary enormously between plants, locations and times of year. In the studies brought together in The Western Herbal Tradition, alpha-thujone ranged from absent to around 56%, while camphor ranged from absent to around 55%.
That makes the frequently repeated explanation that “thujone is what makes mugwort produce vivid dreams” rather less convincing. We simply don't have good human evidence demonstrating that, and not all mugwort even contains remotely comparable amounts of thujone.
There is another important distinction, too: a mugwort tea, tincture, infused oil and essential oil are not interchangeable preparations of the plant. Different methods extract different parts of its chemistry, so evidence or safety considerations relating to one preparation cannot automatically be applied to another.
Mugwort Wasn't Only Drunk
This was one of my favourite discoveries.
When we think about “using a herb”, our modern instinct is often to ask what we can take it as: tea, tincture or supplement. But historically, people worked with mugwort much more broadly. It appears in baths, poultices, fomentations and ointments. One old preparation involved mugwort stems boiled with oil of roses, with the resulting preparation rubbed onto the body before sleep for joint problems. Elsewhere, mugwort was crushed into almond oil and applied externally.
I haven't found an old recipe for a “mugwort dream balm” but I love that our modern balm isn't entirely disconnected from the past.
External mugwort preparations have historical precedent. Oil-based preparations have historical precedent. Even using one before sleep has historical precedent.
What we're doing is taking those old threads and weaving them into something new.
So What Can We Actually Do With Mugwort?
If you've gathered mugwort yourself, the first thing to do is dry it thoroughly.
The leaves and flowering tops are the parts traditionally used, ideally gathered just as the plant begins to flower, when the concentration of volatile oil is higher.
Once dried, you have several options. You can keep some of the herb for herbal infusions, use it aromatically in a dream pillow, or macerate it into a carrier oil for external preparations like the balm we're making here.
For my own harvest, I'm doing a little of each: keeping some dried mugwort in the apothecary, making a simple dream pillow and using the rest to begin an infused oil.
A dream pillow is probably the simplest place to start. Place a small handful of completely dried mugwort into a cotton or linen pouch and keep it beside your pillow. You can use mugwort alone or add a little dried lavender if you want to soften its rather distinctive aroma. Gently squeeze the pouch before bed to release the scent. No elaborate remedy required.
I'm deliberately not including a “dream tea” recipe here: although mugwort has a history of internal use, I haven't found good evidence for a traditional bedtime dose specifically intended to induce dreams.
Making a Mugwort-Infused Oil
For this particular preparation, I've deliberately chosen an oil maceration of the dried herb rather than mugwort essential oil. We're not trying to concentrate its highly variable volatile fraction; we're making a gentle external preparation that also has genuine precedent in the historical use of mugwort oils and ointments.
Here, I'm using the dried leaves and flowering tops and jojoba as my carrier.
Jojoba is technically a liquid wax rather than a conventional vegetable oil and has excellent oxidative stability, which makes it particularly useful for a small preparation like this that may sit beside the bed for several months. A good-quality stable carrier oil can also be used if that's what you have.
Make sure your mugwort is completely dry before you begin. Fresh plant material introduces water into the preparation, increasing the risk of spoilage.
Loosely fill a clean, completely dry glass jar with your dried mugwort.
Pour over enough jojoba (or other chosen carrier oil) to cover the herb completely, making sure no plant material remains sitting above the surface.
Seal and label the jar with the plant, carrier and date, then leave it away from direct sunlight for around 4-6 weeks, gently turning the jar regularly.
When it's ready, strain thoroughly through muslin or a fine filter. Allow any fine sediment to settle before decanting your finished infused oil into a clean, dry bottle.
And it's ready to turn into our balm.
A Modern Mugwort Dream Balm
This isn't an ancient recipe. Neither is it a treatment for insomnia, and I'm not claiming it will make you lucid dream.
Instead, I've taken mugwort's long relationship with sleep, scent and ritual and combined it with what I know as an aromatherapist about using aroma intentionally.
The formulation itself is deliberately simple.
The mugwort infusion remains the main ingredient. Beeswax gives it enough structure to become a balm, while a very small amount of lavender and frankincense creates a distinctive aromatic cue without turning this into a generic essential-oil “sleep blend”.
Mugwort Dream Balm
Makes one 30 g jar
Herbal base
25 g mugwort-infused jojoba oil
5 g beeswax
Aromatic blend
2 drops Lavender essential oil, Lavandula angustifolia
2 drops Frankincense essential oil, Boswellia spp.
I've kept the essential oils deliberately low. Their purpose here isn't to overpower the mugwort or create a strongly sedating blend; they're there to support the aromatic ritual while allowing the herbal preparation to remain at the centre.
Method
Place the mugwort-infused oil and beeswax into a small heatproof jug or bowl and warm gently over a bain-marie until the beeswax has completely melted.
Remove from the heat and allow it to cool slightly while remaining liquid.
Add the lavender and frankincense essential oils and stir thoroughly.
Pour into a clean, dry 30 g jar or tin and allow to cool completely before replacing the lid.
Label with the ingredients and date.
Because this is an anhydrous preparation, keeping water out of it is important. Make small batches, use clean, dry hands or a small spatula, and discard the balm if you notice any significant change in its smell, appearance or texture.
Why Lavender + Frankincense?
We could easily have filled this balm with every essential oil associated with sleep. I deliberately haven't.
Lavender brings a soft, familiar aroma and has a considerably stronger body of research around relaxation and sleep than mugwort itself. Here, though, I'm using only a tiny amount.
Frankincense has a different job. Its dry, resinous aroma gives the blend depth and takes it away from smelling like another conventional lavender bedtime balm.
Neither oil is here because I'm claiming it will induce dreams.
Together they create an aroma distinctive enough to become part of the ritual.
And that brings us to perhaps the part I'm most interested in.
Scent, Ritual + Dreaming
Rather than asking only “Will mugwort make me dream?”, I'm curious about what happens when we repeatedly pair the same distinctive aroma with the same bedtime practice and the intention to remember our dreams.
Our sense of smell is intimately connected with memory, and aromas can become strongly associated with particular people, places and experiences.
So I'm treating the balm as a sensory cue, rather than something that forces a particular physiological state.
At bedtime, apply a small amount to the wrists or upper chest and take a few gentle breaths.
Keep a notebook beside the bed and set the simple intention to remember what you dream.
If you wake during the night remembering something, write down a few words rather than assuming you'll still remember it in the morning.
And when you wake, try staying still for a moment before reaching for your phone.
What were you just dreaming?
A place? A person? A colour? A feeling?
Write down whatever remains.
You don't have to interpret it.
You don't have to make anything mystical out of it.
Just notice.
A home apothecary doesn't always have to be about treating something. Sometimes it can simply give us a reason to pay attention.
A Note on Safety
Mugwort deserves a little caution despite how abundantly it grows around us.
Avoid mugwort during pregnancy and breastfeeding. Its historical use is strongly associated with menstruation and uterine activity, and the herbal source I've used here also advises against its use during pregnancy and lactation.
Mugwort pollen is also an important allergen. Avoid it if you have a known allergy to mugwort or other members of the Asteraceae family. Cross-reactivity with birch, celery, hazelnut, kiwi and peach has also been described in susceptible people.
For topical use, patch testing first is sensible.
I also wouldn't substitute mugwort essential oil for the herbal infused oil in this recipe. As we've seen, the composition of mugwort essential oil can vary enormously and some chemotypes contain substantial concentrations of thujone and camphor.
More concentrated doesn't automatically mean more useful and sometimes the gentler preparation is exactly the point.
References + Further Reading
Much of the historical material, traditional preparations, constituent information and safety discussion in this article draws on the chapter “Artemisia vulgaris, mugwort” in The Western Herbal Tradition. It brings together historical herbal texts with modern phytochemical and safety literature and was particularly useful in tracing how mugwort's uses and reputation have changed over time.
One important caveat when exploring mugwort's history is that identifying Artemisia vulgaris with certainty in older texts isn't always straightforward. Plant names and species identification have shifted over the centuries, and several different Artemisia species - and occasionally plants from related genera - have historically shared or exchanged names.
Historical uses and folklore are included here for educational and cultural context and shouldn't be interpreted as evidence that mugwort can diagnose, treat or prevent a medical condition.
