Wormwood for Antimicrobial Properties

Research suggests that wormwood and related Artemisia species demonstrate broad antimicrobial activity across multiple laboratory-based studies, with essential oils and plant extracts showing inhibitory effects against a range of bacteria, including Staphylococcus aureus, Bacillus cereus, and Micrococcus luteus, as well as certain fungal species such as Candida and Aspergillus. Studies indicate that this activity is attributed to a variety of bioactive compounds identified in these plants, including flavonoids, coumarins, terpenes such as borneol, and chlorogenic acid, with one study additionally exploring how wormwood essential oil could be incorporated into biomaterial coatings with preserved antimicrobial function. The available evidence comes entirely from in vitro laboratory experiments and chemical analyses, with no randomized controlled trials or clinical studies in humans represented in this body of research, which is an important limitation when considering how these findings might translate to real-world applications. One study included in this set, focusing on sage and perilla rather than wormwood itself, was tangential to this topic and did not contribute meaningfully to the antimicrobial evidence base for Artemisia species specifically.
