Drynaria roosii is an epiphytic or rock-growing basket fern from East Asia, valued in traditional Chinese medicine. It grows best mounted on bark or in a humid, bright spot with some air movement.
Drynaria roosii, commonly known as gu-sui-bu, is a species of basket fern of the family Polypodiaceae. The plant is native to Eastern Asia, including eastern China.
It is used in traditional Chinese medicine. This species is also more frequently cited by Asian studies by its synonym, Drynaria fortunei; however, this is an illegitimate name.
Preparations from the rhizomes of Drynaria roosii are used in traditional herbal medicine for aiding in the healing of bone fractures and for treating rheumatoid arthritis.
