Shield fern
Dryopteris crassirhizoma
Dryopteris crassirhizoma is a traditional medicine plant that has not been extensively documented in historical or cultural medical practices. Scientific studies have shown potential benefits, including vasorelaxation through activation of the PI3K/AKT/eNOS pathway and angiotensin II suppression, as well as antioxidant capacity and inhibition of key enzymes involved in glucose and lipid metabolism. However, these findings are preliminary and require further investigation to confirm their relevance and applicability. No significant safety concerns or drug interactions have been reported, but comprehensive clinical trials are needed to fully understand its safety profile and potential interactions with other medications.

What the science says
- The water extract of Dryopteris crassirhizoma promotes vasorelaxation through PI3K/AKT/eNOS pathway activation and angiotensin II suppression.
- A polysaccharide from Dryopteris crassirhizoma showed antioxidant capacity and inhibited key enzymes in glucose and lipid metabolism.
- The study sequenced and analyzed the chloroplast genome of Cyrtomium hemionitis, providing insights into its genetic structure and phylogenetic relationships.
- The study found that seasonal variation primarily influenced leaf traits in ferns, while individual differences dominated root trait variations.
