Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Lichen has been used traditionally in various folk medicine systems to address skin conditions, including dermatitis. Historical records and ethnobotanical surveys mention the topical application of certain lichen species, such as Usnea and Pseudevernia, for skin irritation, rashes, and wounds. The rationale was often based on the presumed antimicrobial or soothing properties of the lichen, derived from compounds like usnic acid and other secondary metabolites. However, the specific application to dermatitis is not well-documented in authoritative historical medical texts, and most references are anecdotal or based on local traditional practices.

From a scientific standpoint, there is limited evidence supporting the efficacy of lichen extracts in treating dermatitis. Some in vitro studies have demonstrated that certain lichen compounds possess antibacterial and anti-inflammatory properties, which could theoretically be beneficial for inflammatory skin conditions. Nevertheless, clinical studies in humans are lacking, and there is no robust scientific validation for the use of lichen as a treatment for dermatitis. As such, its use is primarily grounded in tradition rather than scientific proof, and the evidence supporting its efficacy is weak, warranting a low rating.
