Drug Eyebright
Euphrasia stricta
Euphrasia stricta is a plant traditionally associated with European herbal medicine, particularly in regions such as Scotland. While its specific traditional uses are not well-documented, it has been noted for containing high levels of phenolic acids like 5-O-caffeoylquinic, p-coumaric, protocatechuic, and salicylic acid, which contribute to its potential antioxidant, antimicrobial, and antiproliferative properties. Scientific evidence suggests that Euphrasia stricta may have some activity against Gram-positive bacteria and colorectal adenocarcinoma cells, though the strength of these findings is not yet fully established. There are no major safety concerns or recorded drug interactions for this plant, making it generally safe to use in traditional practices without significant risk.

What the science says
- Euphrasia stricta was found to be susceptible to Scots pine blister rust (Cronartium flaccidum) under laboratory conditions.
- Euphrasia stricta contains the largest amounts of phenolic acids such as 5-O-caffeoylquinic, p-coumaric, protocatechuic, and salicylic acid.
- The study found that extracts from E. officinalis subsp. pratensis and E. stricta showed antioxidant, antimicrobial, and antiproliferative activities.
- Moderate organic fertilization maintained species richness and diversity, while high inputs led to floristic simplification in oligotrophic Nardus stricta grasslands.
