Artemisia, particularly species such as Artemisia princeps (mugwort) and Artemisia vulgaris, has a long history of use in traditional medicine systems across Asia, such as Traditional Chinese Medicine (TCM) and Korean herbal medicine, for managing various skin conditions, including dermatitis. Traditional practitioners use Artemisia-based poultices, washes, or extracts to alleviate symptoms like itching, redness, and inflammation associated with dermatitis and eczema. The rationale for its use is based on its purported cooling, anti-inflammatory, and antimicrobial properties as described in historical texts and ethnobotanical records.

Scientific studies on Artemisia's effectiveness for dermatitis are limited and mostly preclinical. Some in vitro and animal studies suggest that Artemisia extracts exhibit anti-inflammatory and antioxidant activities, and may suppress certain immune responses linked to dermatitis. However, clinical data in humans are sparse; a few small studies and pilot trials suggest some benefit for atopic dermatitis, but these are often of low methodological quality, underpowered, or lack replication. As such, while Artemisia's use for dermatitis is clearly rooted in tradition and there is preliminary scientific interest, robust clinical evidence is lacking. Therefore, its justification is primarily traditional, with a low-to-moderate (2/5) evidence rating for efficacy in dermatitis.
