What Is Polypodium Leucotomos?

Polypodium leucotomos is a tropical fern from Central and South America.

The name — often used in modern biomedicine — is technically a deprecated synonym for the plant name Phlebodium aureum.

Both its thin, green leaves and underground stems (rhizomes) have been used for medicinal purposes for centuries (1Trusted Source).

They contain antioxidants and other compounds that may protect against skin damage caused by inflammation and unstable molecules called free radicals.

Polypodium leucotomos is available in both oral supplements and topical skin creams that contain varying amounts of the plant’s extract.
