Mugwort (Artemisia vulgaris) has a long history of use in traditional medicine systems, particularly in Europe and Asia, for supporting uterine health. Historically, mugwort has been used to regulate menstrual cycles, ease menstrual cramps, and support women during childbirth. In Traditional Chinese Medicine (TCM), mugwort is commonly used in the practice of moxibustion, where dried mugwort is burned near specific acupuncture points to "move qi" and stimulate blood flow, often with the aim of correcting breech presentation in pregnancy or addressing gynecological issues.

However, while traditional uses are well documented, scientific validation of these effects is limited. A few small studies, particularly involving moxibustion with mugwort for breech presentation, suggest some benefit, but the evidence is not robust and often confounded by methodological issues. Most claims regarding its direct effects on the uterus, such as regulating menstruation or relieving cramps, are based on anecdotal or traditional sources rather than controlled scientific studies.

In summary, mugwort’s reputation for supporting the uterus is primarily upheld by traditional usage rather than strong scientific evidence. While it remains popular in herbal and folk medicine, more rigorous research is needed to substantiate its efficacy for uterine health.
