Mugwort Through History: European and Asian Herbal Traditions

Few plants have as geographically widespread a documented history as mugwort. Across Europe, China, Japan, and other parts of Asia, plants in the Artemisia genus have been cultivated, used, and written about for centuries — in herbal medicine, in food, in ritual, and in everyday household practice.

That breadth is mugwort’s most interesting historical characteristic. It is not primarily a dream herb with a long history; it is a plant with a long and varied history that includes, among many other things, some associations with dreaming in certain traditions. Understanding that distinction matters for reading the historical record accurately.

A Note on Evidence

As with all articles in this series, we use a four-tier framework to distinguish between different kinds of historical evidence:

1. Documented historical evidence — archaeological, textual or primary sources
2. Recorded traditional use — ethnobotanical or anthropological documentation
3. Later herbal tradition — practices recorded in later herbal texts or compendiums
4. Modern interpretation — how these traditions are understood or adapted today

These are not four levels of truth but four different kinds of evidence. When the surviving evidence is incomplete or disputed, we say so rather than trying to resolve the uncertainty.

What “Mugwort” Actually Means Botanically

“Mugwort” is not a single plant. It is a common name applied to several species within the large Artemisia genus, which contains several hundred species distributed across temperate regions of the Northern Hemisphere.

In European contexts, “mugwort” most commonly refers to Artemisia vulgaris, a widespread plant native to Europe, Asia, and parts of North Africa. In Chinese traditional medicine, the primary species used — particularly in moxibustion — is Artemisia argyi, sometimes called Chinese mugwort or Chinese moxa. In Japan, the plant known as yomogi is Artemisia princeps, a species closely related to but distinct from both A. vulgaris and A. argyi.

These species are botanically related and share some characteristics, but they are not identical. Historical and traditional uses documented for one species cannot be automatically assumed to apply to another. Where the historical record specifies a species, this article names it. Where it does not, we note the uncertainty.

This botanical complexity is one reason why treating “mugwort” as a single unified plant with a single unified history is misleading. The interesting story is precisely that different Artemisia species developed cultural significance in different parts of the world, in different contexts, apparently independently.

European Traditions

Artemisia vulgaris has a long documented history in European herbal traditions, with references spanning classical antiquity through the medieval period and into early modern herbalism.

Documented historical evidence places mugwort in classical Greek and Roman texts. Dioscorides references Artemisia in De Materia Medica, and the genus name itself is traditionally associated with Artemis, the Greek goddess — though the precise etymology and which species Dioscorides described are matters of scholarly discussion. Pliny the Elder also references Artemisia in his Naturalis Historia.

Recorded traditional use in European folk medicine is extensive and geographically widespread. Artemisia vulgaris appears in Anglo-Saxon herbal texts, including the Lacnunga and the Old English Herbarium, where it is listed among plants used in a range of preparations. It appears in medieval European herbals and in the records of monastic gardens. Its uses in these sources are varied — it was not associated with a single purpose but appeared in contexts ranging from culinary use to preparations for travellers to ritual protective use.

Later herbal tradition consolidated mugwort’s place in European herbalism. It appears in medieval European herbal compendiums, including works from the Benedictine tradition, and in numerous early modern herbals. John Gerard’s Herball (1597) and Nicholas Culpeper’s Complete Herbal (1653) both include mugwort, associating it with a range of uses that reflect the humoral medical frameworks of their time rather than modern categories.

One consistent thread across European folk traditions is mugwort’s association with travel and protection — it appears in accounts of plants placed in shoes for long journeys, and in protective charms and household uses. These associations are well-documented in later herbal and folklore sources, though their origins are difficult to trace precisely.

Chinese Traditions & Moxibustion

In Chinese traditional medicine, Artemisia argyi — Chinese mugwort — has a documented history of use in moxibustion that is among the most specific and well-evidenced applications of any Artemisia species anywhere in the world.

Documented historical evidence for moxibustion is substantial. The practice is described in classical Chinese medical texts including the Huangdi Neijing (Yellow Emperor’s Classic of Medicine), traditionally dated to the Han dynasty period, and in later texts including the Bencao Gangmu (Compendium of Materia Medica) compiled by Li Shizhen in the 16th century. Archaeological evidence for moxibustion-related practices has been found at sites associated with early Chinese medicine.

Moxibustion involves burning dried Artemisia material — moxa — at or near specific points on the body. The dried and processed leaves of Artemisia argyi are the primary material used, valued for their burning properties. This is a specific, documented, and still-practised application with a textual record extending back at least two thousand years.

It is worth being clear that moxibustion is a distinct practice from the ingestion of mugwort as an infusion or food. The two applications involve different preparation methods, different parts of the plant, and different theoretical frameworks. They should not be conflated.

Chinese traditional medicine also documents Artemisia species in other contexts — the Bencao Gangmu lists numerous Artemisia species with different documented uses — but moxibustion represents the most specific and continuously documented application.

Japanese Yomogi Traditions

In Japan, Artemisia princeps — known as yomogi — has a documented history that is notably different in character from both the European and Chinese traditions. Its most prominent historical role is culinary and seasonal rather than medicinal.

Documented historical evidence for yomogi in Japanese culture is found in classical literature and poetry. The plant appears in the Man’yōshū, the oldest existing collection of Japanese poetry, compiled in the late 8th century CE, where it is referenced in seasonal and pastoral contexts. It appears in Heian-period literature as a plant associated with neglected gardens and the passage of time — a cultural association that reflects its tendency to grow abundantly in uncultivated ground.

Recorded traditional use of yomogi in Japanese food culture is well-attested. The plant is used in kusa mochi (草餅) — a traditional rice cake coloured and flavoured with yomogi — and in other seasonal foods associated with spring. This culinary use is documented across centuries and remains a living tradition today.

Yomogi also appears in Japanese folk medicine and in ritual contexts, including use in Hinamatsuri (the Doll Festival) and other seasonal observances. These uses are documented in historical and ethnographic sources, though the evidence is more varied in character than the culinary record.

The Japanese yomogi tradition is a useful reminder that the same genus of plant can occupy very different cultural roles in different contexts. Artemisia princeps in Japan is primarily a food plant with seasonal and poetic associations — not a medicinal or ritual plant in the way that Artemisia argyi is in Chinese medicine or Artemisia vulgaris in European herbalism.

Culinary & Everyday Uses

Across all three traditions, Artemisia species have documented culinary and everyday uses that are often overlooked in favour of their more dramatic associations.

In Europe, Artemisia vulgaris has a documented history as a culinary herb, particularly in the flavouring of fatty meats and in brewing — it was used as a bittering agent in ale before hops became dominant in European brewing. This culinary use is documented in medieval and early modern sources and represents a practical, everyday relationship with the plant that predates or runs alongside its herbal associations.

In Japan, yomogi’s culinary role is central to its cultural identity, as described above.

In China, Artemisia species appear in food contexts as well as medical ones, though the medical and moxibustion uses are more extensively documented in the surviving textual record.

Folklore, Dreaming & What We Can Establish

Mugwort’s association with dreaming is real in the sense that it appears in European folklore sources — but it requires careful handling.

Later herbal tradition and folklore do include references to mugwort and dreams. These appear in European folk sources, in some early modern herbal texts, and in the broader tradition of plants associated with sleep and nocturnal experience. However, the evidence for mugwort as a specifically dream-associated plant is considerably thinner and later than its evidence as a culinary, medicinal, and protective plant.

The origins of the dreaming association are difficult to establish. It does not appear prominently in the earliest European herbal sources. It becomes more visible in later folklore compilations and in 19th and 20th century folk medicine records — a period when European folk traditions were being actively collected and sometimes romanticised by folklorists.

Modern interpretation has amplified the dreaming association significantly. Mugwort’s inclusion in the modern “dream herb” category — alongside Calea, Blue Lotus, and others — reflects 20th and 21st century Western interest in lucid dreaming and altered states rather than a continuous ancient tradition. The historical continuity of mugwort’s dreaming associations is genuinely difficult to establish from the primary sources.

This does not mean the association is invented. It means it should be understood as a later folk tradition of uncertain origin rather than as ancient documented practice — which is precisely what the four-tier evidence framework is designed to distinguish.
