Asian Plantain (Plantago asiatica) has a long history of use in traditional medicine systems, particularly in East Asia, for managing various skin conditions, including dermatitis. In Traditional Chinese Medicine (TCM), plantain leaves are believed to have cooling and detoxifying properties and are often used topically or internally to alleviate inflammation, itching, and redness associated with skin disorders such as eczema and dermatitis. Historical herbal texts and contemporary ethnobotanical surveys document its frequent application for these purposes.

However, the scientific evidence substantiating these traditional uses is limited. While some laboratory studies have demonstrated that Plantago species possess anti-inflammatory, antimicrobial, and antioxidant properties—effects that could theoretically benefit dermatitis—robust clinical trials in humans are lacking. The majority of available evidence is based on in vitro studies, animal models, or anecdotal reports rather than well-designed clinical research. As such, the use of Asian Plantain for dermatitis remains primarily justified by tradition, with only preliminary scientific support.

In summary, Asian Plantain is traditionally used to support the treatment of dermatitis, but current scientific validation is insufficient to recommend it as a primary therapy based on evidence-based medicine.
