Cibotium barometz is rather common in S subtropical regions and tropical regions, usually growing with Alsophila spinulosa, Diplopterygium chinense, and Dicranopteris pedata, sometimes abundant and forming a dense community. It is an indicator species of acidic soils in tropical and subtropical areas, mainly distributed in S and SW China, primarily in Guangdong, Guangxi, and Guizhou, but also in Sichuan and Yunnan. The most northerly distribution of this species in China reaches the Chang Jiang in Chongqing.

The rhizome of this plant is very thick, woody, and covered by long, soft, golden-yellow hairs, appearing like a golden-haired dog. Therefore, the plant is called "Jinmao Gouji" (golden hair dog), or "Huanggoutou" (yellow dog’s head) in China. It is a famous traditional Chinese herbal medicine known as "Gouji" (cibot rhizome, "rhizoma cibotii"). Hairs of the rhizome and stipe are also used as a wound dressing and to stanch blood loss. It is listed in CITES Appendix II. Conservation and sustainable use should be attained.
