Fragrant Fern
Dryopteris fragrans
Dryopteris fragrans is a fern traditionally not associated with any specific medicinal uses. Scientific research has shown that three HMGR genes from this plant exhibit differential expression under abiotic stress conditions and may enhance stress tolerance when overexpressed in tobacco plants, suggesting potential applications for improving crop resilience. Aspidinol B, isolated from Dryopteris fragrans, demonstrated significant inhibitory activity against Fusarium species, which could be useful for controlling potato dry rot. Additionally, supercritical CO2 extraction of the aerial parts of the plant identified a total of 141 bioactive compounds, indicating its potential in various biological activities. To date, no major safety concerns or recorded drug interactions have been noted with Dryopteris fragrans.
