Polypodium leucotomos
Tropical American fern with clinical evidence for skin UV protection.
Polypodium leucotomos (Samambaia) is a tropical fern with Level C clinical evidence for oral photoprotection. It contains phenolic compounds such as caffeic, ferulic, and vanillic acids. Traditionally used for skin diseases, it is now employed as an oral sunscreen and adjunct in psoriasis and vitiligo.
The extract acts as a potent antioxidant, scavenging free radicals and reducing UV-induced oxidative stress. It inhibits NF-κB activation and downregulates pro-inflammatory cytokines (e.g., TNF-α, IL-6). Phenolic compounds also inhibit tyrosinase and melanocyte activation, contributing to photoprotection. Additionally, it modulates immune responses by affecting dendritic cell maturation and T-cell activity.
