Japanese Sacred Lily

Rohdea japonica

Rohdea japonica, a plant native to East Asia, has not been traditionally used for medicinal purposes. Scientific studies have shown promising results with RJP60-1, a polysaccharide derived from Rohdea japonica, demonstrating significant anti-ulcerative colitis (UC) effects by modulating gut microbiota and reducing pyroptosis. Additionally, the stems of both Epipremnum aureum and Rohdea japonica have been found to remove formaldehyde, with removal rates of 40.0% and 61.6%, respectively. While two pectic polysaccharides from Rohdea japonica exhibit varying structural features and antioxidant capacities, no major safety issues or drug interactions have been recorded for this plant.
