Chain Fern Rhizome Pieces (Cibotium Barometz)

Chain Fern Rhizome Pieces (Cibotium barometz), known in Traditional Chinese Medicine as Gou Ji (狗脊), are warm, bitter, and strengthening rhizome segments traditionally used to tonify the liver and kidneys, strengthen the sinews and bones, and dispel wind-dampness. Harvested from the thick, fibrous roots of the Cibotium chain fern, these dried pieces are carefully prepared to preserve their dense texture and restorative properties.

In TCM, Gou Ji is especially valued for its ability to support joint flexibility, ease lower back and knee discomfort, and stabilize the body’s core energy, particularly in cases of weakness, stiffness, or wind-cold-damp bi syndrome. It is often used in formulas that address chronic musculoskeletal issues, degenerative joint concerns, or post-injury recovery. Additionally, Gou Ji is sometimes used to help secure and stabilize the lower body, making it helpful for issues like urinary leakage or vaginal discharge due to deficiency.

When decocted, Chain Fern Rhizome Pieces produce a deep, earthy infusion with a mild, slightly bitter flavor. They pair well with herbs like Du Zhong (Eucommia), Xu Duan (Dipsacus), and Sang Ji Sheng (Taxillus) in classical yang-tonifying and bone-strengthening formulas.

Each batch of Chain Fern Rhizome Pieces (Cibotium barometz) is carefully sliced, dried, and processed to preserve its traditional therapeutic properties and herbal potency. Whether used in restorative decoctions, yang-tonifying blends, or joint-supporting formulas, Gou Ji offers a time-honored and powerful means to strengthen the body’s foundation, support structural health, and dispel damp-cold stagnation.
