Abstract

Aim. Idiopathic photodermatoses (IP) are a recurrent, acquired sunlight-induced rash of delayed onset, appearing after exposure to ultraviolet radiation in susceptible individuals. The aim of this study was to assess the photoprotective activity of polypodium leucotomos (PL) in IP. Methods. Fifty-seven patients affected by IP were recruited for the study (53 with polymorphic light eruption and 4 with solar urticaria). The use of UV protection filters or other drugs that could in some way interfere with exposure to light were excluded. All patients exposed themselves to sunlight while consuming 480 mg/day of PL extract orally. A statistical evaluation' of the basal clinical conditions compared to those after sunlight exposure with PL was performed. Results. About 73.68% of the patients had a benefit from the administered PL, with a significant reduction of skin reaction and subjective symptoms. No side effects were observed. Results were statistically significant (P
