Wild ferns

Wild ferns

　　　Ferns, a type of pteridophyte, refer to plants in the Pteridaceae family. They are perennial herbs, about one meter tall, with creeping rhizomes under the soil covered in fine brown hairs. The leaves are large and have multiple levels of pinnate compound structure. Ferns are highly adaptable and often grow in dense clusters. Their rhizomes are rich in starch, which can be extracted for food or medicinal use. The young shoots, known locally as wild ferns, are a seasonal delicacy, believed to have health benefits such as reducing intense heat, promoting urination, lowering blood pressure, clearing heat, detoxifying, diuretic effects, stopping bleeding, and reducing hypertension.

　　Wild ferns are widely distributed throughout Liangshan, especially in counties and cities such as Meigu, Leibo, Zhaojue, Xichang, Dechang, and Mianning, where they are found in greater abundance. As a wild plant, currently only 200 tons of dried ferns are processed and exported each year, with no deep processing yet underway. Given the current trend toward green foods, the market potential is very promising. With proper promotion, finely packaged dried ferns and fresh-preserved ferns are expected to become fashionable foods in large and medium-sized cities. Boxed dried ferns produced by Xichang Agricultural College and Panxing Company have become a popular local specialty enjoyed by many tourists visiting Liangshan.
