Mugwort is a common name applied to several different aromatic, flowering plant species within the genus *Artemisia*.

While the term is broad, it often refers to specific species depending on the region. In Europe, it most commonly describes *Artemisia vulgaris*, also known as common mugwort. In East Asia, the name frequently refers to *Artemisia argyi*, often called Chinese mugwort. Other notable species include *Artemisia princeps*, which is known as *ssuk* in Korea and *yomogi* in Japan. These plants are significant due to their long history of use in culinary, medicinal, and spiritual practices.

The chemical makeup of mugwort contributes to its diverse uses. The plant contains essential oils that vary based on the specific species and the environment where it grows.

These oils include compounds such as camphor, cineole, and borneol. A key component is thujone, a neurotoxin that appears in different concentrations depending on soil and climate. The presence of these oils gives the plant its characteristic scent and insecticidal properties. In fact, all parts of the plant can act as an insecticide, particularly against insect larvae.

Culinary uses for mugwort are widespread across many global cultures. The leaves and young spring shoots have an aromatic and slightly bitter flavor. These can be eaten raw or cooked to season meats and fish. In Germany, the plant is used to season roast goose during Christmas. In China, mugwort is used as a flavoring and colorant for seasonal rice dishes. Japanese cuisine features mugwort in sweets like *yōkan* and *kusa mochi*, which are rice cakes. In Korea, the plant is a staple in spring soups, such as those made with clams, and in various steamed rice cakes.

In the realm of traditional medicine, mugwort has been utilized since at least the Iron Age. In East Asian traditions, a specific practice called moxibustion is performed. This involves using *moxa*, which is pulverized, aged mugwort. Practitioners burn the moxa on specific acupuncture points of the body to achieve therapeutic effects. There is a belief that this can help move a fetus into the correct position before birth. In India, the plant is known as *nāgadamanī* in Sanskrit and is used in Ayurveda to treat feelings of malaise or unease.

Indigenous peoples of North America also utilized mugwort for many different medicinal purposes. They prepared strong, bitter teas to treat fevers and colds. The leaves were sometimes crushed into a snuff to help with headaches or nosebleeds. Some tribes used the plant in washes to treat skin conditions like eczema or bruises. They even used the smoke from the plant to disinfect certain areas. Because some varieties were used to regulate menstrual cycles, they were sometimes called "women's sage."

Historical records show that mugwort has held deep cultural and spiritual significance. In the 10th century, it was included in the Anglo-Saxon *Nine Herbs Charm*. During the European Middle Ages, it was viewed as a protective herb against evil spirits. Roman soldiers reportedly placed the plant in their sandals to prevent foot fatigue and cramps. In China, the plant's importance is reflected in literature, with poems mentioning it as far back as 3 BC. The famous poet Su Shi also wrote about the plant in the 11th century.

Despite its many uses, mugwort requires careful handling due to potential health risks. The thujone found in the plant can be toxic in high concentrations. Studies have linked high levels of thujone to seizures, and it may cause an abortive effect. Consequently, medical experts advise that it should not be used during pregnancy without professional supervision. Additionally, mugwort pollen is a major cause of hay fever and allergic asthma in parts of Europe, Asia, and North America. This pollen typically travels less than 2,000 meters and is most concentrated between 9 and 11 am.
