Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Drynaria, specifically the rhizome of Drynaria fortunei (commonly known as Gu Sui Bu in Traditional Chinese Medicine), has a long history of use in East Asian herbal medicine. Traditionally, it is used to strengthen bones and tendons, and is also included in formulations for oral health, such as the treatment of loose teeth and bleeding gums. The rationale in traditional texts is based on the theory that strengthening the bones and "kidney essence" indirectly benefits the gums and teeth, since teeth are considered "the extension of bone" in traditional Chinese medical philosophy.

Modern scientific research on Drynaria’s effects specifically on gums is limited. Most studies focus on its bone-healing properties, showing that flavonoids in Drynaria can stimulate osteoblast activity and bone regeneration in animal models. There is sparse clinical evidence, however, directly linking Drynaria to improved gum health or periodontal disease outcomes. Some in vitro studies suggest anti-inflammatory and antimicrobial effects, which could theoretically benefit gum tissues, but these findings are preliminary and have not been confirmed in human clinical trials focused on the gums.

In summary, the use of Drynaria for supporting gum health is primarily traditional with some indirect scientific plausibility based on its effects on bone and connective tissue, but direct evidence for efficacy in gum health is lacking. Therefore, the evidence level is rated at 2 out of 5.
