Cibotium barometz
Also known as golden chicken fern, woolly fern, vegetable lamb of Tartary, chain fern, cibotium, gou ji, gǒu jǐ.
Gou ji is a large tree fern of southern China, Indochina and the Malay Peninsula, named for its thick rhizome that is covered in dense golden brown hairs and, when cut, resembles a dog's spine. The sliced, dried rhizome is the medicine; the golden hairs are kept separately as a traditional styptic. In Chinese medicine it is a warm tonic for the liver and kidney that specifically strengthens the lower back, sinews and bones, and it is a routine ingredient in formulas for the aching, weak lumbar spine of aging.
