Osmundastrum cinnamomeum, (Osmunda cinnamomea), Cinnamon Fern.

Osmundastrum cinnamomeum, (Osmunda cinnamomea), Cinnamon Fern, is a widespread fern of swamps, bogs, and wet woodlands from the Americas (Canada south to Paraguay), and East Asia. It has no closely related species in the same family (Osmundaceae), and is a monotypic living fossil, essentially unchanged for 200 million years. Rootstock (rhizome) was used for its demulcent, mild astringent, properties, and as a flavoring to other medicine. When boiled in milk it is said to produce a fine mucilage. Formerly used in diarrhea, dystentery, and for rickets.
