Campylandra fimbriata (now often recognized as Rohdea japonica in some botanical literature) has a history of use in traditional medicine, particularly in regions of East and Southeast Asia. Traditional systems, including some strands of Chinese and folk medicine, have reportedly used the plant’s rhizome and other parts in remedies aimed at alleviating general pain and discomfort. The plant is sometimes cited for its purported anti-inflammatory or analgesic properties, although these claims are based largely on ethnobotanical records and anecdotal reports rather than rigorous clinical studies.

Scientific validation for these uses is limited. The available research consists primarily of in vitro and animal studies, some of which suggest that extracts of related species may have mild anti-inflammatory or analgesic effects, possibly due to the presence of steroidal saponins or glycosides. However, there have been no robust human clinical trials directly examining the efficacy of Campylandra fimbriata for pain management. The traditional use is thus supported by historical and cultural documentation rather than strong scientific evidence. The overall quality and quantity of data supporting its use for pain is limited, and traditional use should not be equated with proven efficacy or safety.
