Rating (out of 5): 3

Drynaria, particularly Drynaria fortunei (commonly known as Gu Sui Bu), is a fern widely used in traditional Chinese medicine (TCM) to support bone health and recovery from fractures. The traditional use of Drynaria dates back many centuries, with classic TCM texts describing its application in promoting bone healing, strengthening the bones and tendons, and alleviating symptoms associated with bone weakness. It is commonly included in herbal formulas prescribed for conditions such as osteoporosis, bone injuries, and dental issues.

Scientific validation for these traditional uses is emerging but remains limited. Preclinical studies (in vitro and animal models) suggest that extracts of Drynaria rhizome may promote osteoblast proliferation (cells responsible for bone formation), enhance bone mineral density, and stimulate bone regeneration. Some studies have identified active compounds such as naringin, which has been shown to have osteogenic effects. However, robust clinical trials in humans are lacking, and most evidence is derived from laboratory studies and traditional practice. Therefore, while there is a strong historical basis for its use and some supportive preclinical data, more high-quality clinical research is needed to fully substantiate these claims.
