Polypodium Leucotomos Extract (PLE)
Polypodium is a fern, a relatively primitive plant that represents a bridge between green algae and higher plants. This evolutionary position means that some of the biochemicals found in polypodium are very different from what you would find in flowering plants.
Polypodium leucotomos grows in Ecuador and Honduras. Study of the many biochemicals present in this fern is a time-consuming process and we don’t know which components are responsible for the beneficial properties of PLE; although calagualine, a saponin, has been mentioned as responsible for some of the extract’s beneficial qualities. PLE has anti-irritation activity and helps with chapped, red skin. This powerful antioxidant also reduces free radicals formed by the sun, pollution, and heat.
