What is mugwort used for in folklore?
Mugwort grows on roadsides and waste ground across Europe and Asia. Its leaves are dark green above and downy white beneath, and the whole plant has a sage-like bitter smell. The genus is named Artemisia, which ancient writers connected with the goddess Artemis.
Mugwort’s folklore gathers around three things. It is a herb of the road, tied to the body or put in the shoe against tiredness. It is a herb of midsummer, worn as a girdle at the bonfires of Saint John's Eve and thrown into the flames with the year's ill luck. And in present-day practice it is a herb of dreams, placed in a sachet by the pillow. A related species supplies the moxa burned in Chinese moxibustion.

What sets Mugwort apart
Mugwort is a boundary herb. Its uses cluster at thresholds: the start of a journey, the turn of the year at midsummer, the edge of sleep. Unlike the resins, which come from far countries, it is a common weed, free to anyone who walks a lane, and its lore is correspondingly domestic. The old charm sources praise it as a protector; its present fame as a dream herb is a recent layer added to that record.
- Botanical name: Artemisia vulgaris, of the daisy family
- Recognised by: leaves dark green above and silvery white beneath
- Pliny: a traveller carrying it feels no weariness (Natural History, 1st century)
- Nine Herbs Charm: named first and called the oldest of herbs, Lacnunga, about 1000
- Midsummer name: Saint John's girdle, worn and burned at the bonfire
- Hazards: thujone content; a major hay fever pollen; warned against in pregnancy
Often mistaken for something else: Wormwood, Artemisia absinthium, is a greyer, far more bitter relative used in absinthe; mugwort is the taller green roadside species with white-backed leaves.
The story behind Mugwort
Pliny the Elder wrote in the first century that a traveller who carries artemisia feels no weariness. The Old English Nine Herbs Charm, preserved in the Lacnunga manuscript of about the year 1000, addresses mugwort first and calls it the oldest of herbs. German custom named it Saint John's girdle. Before hops became usual, it was one of the bitter herbs used to flavour ale. The reputation for dreams is poorly attested in old sources and seems to have grown mainly in twentieth-century herbals.
Why Mugwort matters
Few European herbs have so long a written trail in charm and custom, from Pliny through the Anglo-Saxon charms to midsummer rites.
How to read Mugwort
It is hung dry by a door, kept in a dream sachet or laid on a midsummer altar; tables of correspondences give it to the Moon or to Venus.
Mugwort in practice: an example
A dried sprig tucked into a small cloth bag and left on a bedside table is the commonest modern use of the plant.
Where readings of Mugwort go wrong
Mugwort is kept for scent and symbol, not for eating or drinking: it contains thujone, has long been warned against in pregnancy, and its pollen is a common cause of hay fever.

Common questions
What is mugwort used for in folklore?
Chiefly for protection on journeys, for the midsummer fires of Saint John's Eve and, in modern practice, for dreams. It also appears in the Anglo-Saxon Nine Herbs Charm as a guard against poison and infection.
Does mugwort cause lucid dreams?
Many people say so, and the belief is widespread in present-day herb lore. No controlled study supports it, and the claim is hard to find in sources older than the last century.
Is mugwort safe?
As a dried plant kept in a sachet it is harmless to most people, though those with hay fever may react to it. It is not a plant to take internally on the strength of folklore, and tradition itself warns pregnant women away from it.
