Pyrrosia Tincture & Alcohol-Free Extract

Pyrrosia (Pyrrosia lingua) is the tongue fern, an evergreen fern of the polypody family, Polypodiaceae, native to China, Japan, Korea and Indochina, where it grows on shaded rocks and tree trunks. A slender creeping rhizome covered in brown scales produces simple, undivided, tongue-shaped fronds 10 to 30 cm long on wiry stalks. The upper surface is dark green and leathery, while the underside is densely covered in pale, star-shaped hairs and, in season, rust-brown spore clusters. In China the fronds are called shi wei, "stone reed". We extract the dried leaf.
