Polypodium Leucotomos

Polypodium leucotomos, also known as Calaguala, Fernblock, or Heliocare, has gained recognition in traditional medicine for its therapeutic applications, particularly in the treatment of various skin disorders. Widely used in South America and Spain, P. leucotomos extracts have demonstrated efficacy in addressing conditions such as psoriasis, atopic dermatitis, and vitiligo. Notably, it provides protection against sun-induced skin damage, making it a valuable supplement for sensitive skin, marketed under different names. Studies suggest its moderately potent effects in shielding against UV-induced skin cell radiation, acting as both an antioxidant and anti-inflammatory agent. The herb's unique quality lies in its oral ingestion, showcasing DNA protection in rats. While human interventions highlight its positive influence on skin conditions, including suppression of erythema and assistance for those hypersensitive to sunlight, further research is needed for comprehensive support. P. leucotomos has been explored for its potential in addressing vitiligo and upper respiratory tract infections, showing promise but requiring more robust evidence. Additionally, clinical studies have demonstrated its oral consumption as a photoprotective strategy, complementing traditional UV filters like sunscreen. Despite its novel qualities, P. leucotomos remains a herb with potential benefits, particularly in dermatologic contexts, albeit with the need for more extensive research support.
