“P. Leucotomos extract 240mg taken twice daily for 60 days was safe and effective means for reducing the damaging effects of UV radiation.”
This excerpt is from a new American publication which essentially confirms the safety and photoprotection efficacy of oral administration of Fernblock (2 capsules 240mg daily for 60 days). Safety assessments included physical examination, vital signs, and clinical laboratory parameters such as hematology, comprehensive metabolic panel, and prothrombin time-partial thromboplastin time (PT-PTT).
After 60 days treatment, there were no changes in any safety assessments, demonstrating an "excellent safety profile". In terms of photoprotection, subjects taking Fernblock experienced increased MED, decreased UV-induced erythema intensity and reduced sunburn episodes versus placebo group.
Fernblock is an extract from Polypodium leocotomos, a fern originating in Central America that developed a natural mechanism to protect itself from sun radiation during its adaptation from life in water to life on land and is the basis of Heliocare technology.
