Common eyebright

The Common Eyebright (<em>Euphrasia nemorosa</em>) is a small annual plant belonging to the genus Euphrasia within the family Orobanchaceae. This species is a hemiparasite, typically attaching its roots to the roots of neighbouring grasses and other plants to obtain water and nutrients, while also performing photosynthesis. It is often found in diverse terrestrial habitats ranging from tropical forests to temperate regions, including grasslands, heathlands, and woodland margins. Geographically, <em>Euphrasia nemorosa</em> is distributed across Europe, with confirmed records in countries including Belgium, Denmark, Finland, and France, as well as presence in North America in Canada and the United States. The species is assessed as Least Concern on the IUCN Red List, indicating a stable global population without immediate threat of extinction. Biological traits of this species remain poorly documented in the scientific literature, including specific data on lifespan, body size, and diet. The common name "eyebright" reflects its historical use in herbal medicine for treating eye ailments, though this application is not supported by modern clinical evidence.
