Mugwort (Artemisia vulgaris) has a long history of use in traditional medicine systems, especially in East Asia and Europe. Traditionally, mugwort has been used to treat symptoms of colds, such as congestion and cough, often as a tea, inhalant, or included in herbal mixtures. Folk medicine practices suggest that mugwort may act as a mild decongestant and expectorant, possibly due to its volatile oils and aromatic compounds, which are thought to help open the airways and reduce symptoms of colds. However, there is very limited scientific research specifically validating mugwort’s efficacy as a decongestant or its direct effect on cold symptoms. Most available evidence is anecdotal or derived from traditional herbal texts rather than controlled clinical studies. Some laboratory studies have found that mugwort contains compounds with mild anti-inflammatory and antimicrobial properties, which could theoretically support its use in respiratory conditions, but these findings have not been robustly translated into clinical practice. Therefore, while mugwort is indeed used traditionally for cold symptoms, its effectiveness as a decongestant is not well-supported by modern scientific evidence.
