Common Bracken or Eagle Fern 蕨类 (Pteridium Aquilinum) in Mossy Forest of Gunung Brinchang, Cameron Highlands. It is a species of fern found in temperate & subtropical regions in both hemispheres. The extreme lightness of its spores has led to its global distribution. Bracken is an adaptable plant ready to colonise disturbed areas. It can even be aggressive in countries where it is native, such as England, where it has invaded the North Yorkshire moors.
Common bracken is a herbaceous perennial plant, deciduous in winter. The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, growing up to 1m tall. The main stem is up to 1 cm diameter at the base. It dies back to ground level in autumn. Sporangia are formed in sori on the underside of the frond.
Bracken is a widely eaten vegetable in Korea, Japan & parts of China. In Korea, bracken is often eaten as namul or gosari. It is also a classic ingredient of bibimbap.
The plant contains the carcinogenic compound ptaquiloside. High stomach cancer rates are found in Japan & North Wales, where the young stems are used as a vegetable, but it is unknown whether bracken plays any part at all. Consumption of ptaquiloside-contaminated milk is thought to contribute to human gastric cancer in the Andean states of Venezuela. The spores have also been implicated as carcinogens.
