Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Polypodium, particularly Polypodium leucotomos, has a history of traditional use in some cultures for various skin conditions, including rashes and hives. Folk medicine in Central and South America has employed extracts of this fern for skin health, sun protection, and inflammatory skin issues. However, direct historical documentation specifically targeting its use for rashes or urticaria (hives) is limited and often generalized under broader claims of “skin soothing” or “anti-inflammatory” benefit.

Scientifically, Polypodium leucotomos extract has been studied mostly for its photoprotective properties and potential to reduce damage from UV radiation, with some evidence suggesting it may help in conditions like polymorphic light eruption and vitiligo. A few small clinical studies and case reports have noted improvements in inflammatory skin responses, but robust data specific to acute allergic rashes or hives are lacking. Most available evidence is extrapolated from its anti-inflammatory and antioxidant effects observed in vitro or in animal models.

In summary, the use of Polypodium for rashes and hives is primarily based on tradition, with some emerging but limited scientific rationale supporting a general anti-inflammatory effect. Rigorous clinical trials targeting rashes or hives specifically are lacking, and the evidence base is not strong.
