Fragrant Fern
Dryopteris fragrans
Dryopteris fragrans is a fern traditionally used in East Asian medicine for various conditions but lacks specific documented traditional uses. Scientific studies have identified three HMGR genes and 141 bioactive compounds, including new constituents, suggesting potential applications in enhancing plant tolerance to abiotic stress and controlling fungal infections like potato dry rot. While the evidence indicates promising biological activities, more research is needed to confirm these findings. No major safety concerns or drug interactions have been recorded for Dryopteris fragrans, but further investigation is recommended to fully understand its potential benefits and risks.

What the science says
- This study identified three HMGR genes in Dryopteris fragrans and showed their differential expression under abiotic stress, with transgenic tobacco showing enhanced tolerance.
- Aspidinol B, isolated from Dryopteris fragrans, showed significant inhibitory activity against Fusarium species, potentially useful for controlling potato dry rot.
- The study identified 141 bioactive compounds in Dryopteris fragrans using supercritical CO2 extraction, including several new constituents.
- The ectopic expression of Dryopteris fragrans DfMTPSL6, regulated by DfWRKY16/45, enhanced drought tolerance in tobacco plants.
