What does euphrasia mean?
Euphrasia is the scientific name for a genus of small annual flowering plants popularly called eyebright, belonging to the broomrape family (Orobanchaceae). These low-growing herbs bear tiny white or pale violet flowers, often marked with yellow, and are semi-parasitic, drawing some nutrients from the roots of neighboring grasses. They flourish in short grassland, pastures, and moorland across Europe and other temperate regions. The name also refers to the dried herb prepared from these plants, which has a long history in Western herbal and homeopathic traditions as a treatment for eye ailments such as conjunctivitis, styes, and general irritation — hence the folk name eyebright, reflecting the old 'doctrine of signatures' belief that a plant's appearance signals its healing use. Today euphrasia appears chiefly in botanical literature and natural-health contexts, while most readers will meet it under its gentler common name.

"Botanists surveyed the chalk downland for rare species of Euphrasia."
When referring to the botanical genus, Euphrasia is conventionally capitalized and italicized.

"The apothecary stocked euphrasia alongside chamomile and calendula."
In this sense the word is usually lowercase and treated as a mass noun.
As a botanical count noun referring to individual species or plants, the regular plural 'euphrasias' is used; when denoting the medicinal herb, the word is normally uncountable and has no plural.
"Several distinct euphrasias grow on the coastal cliffs."
Named from the Greek for 'good cheer,' this unassuming meadow flower earned its common name, eyebright, because herbalists swore it could clear sore eyes.

Etymology of euphrasia
The word euphrasia comes from Latin euphrasia, itself borrowed from Greek euphrasia meaning 'good cheer' or 'gladness', derived from the verb euphrainein ('to delight'), formed from eu- ('good') plus phren ('mind'). Linnaeus applied the name to the eyebright genus in the 18th century, alluding to the plant's reputedly cheering effect on the eyes. It shares the productive Greek eu- prefix with words such as euphoria and euphemism, though those derive from different second elements.
How euphrasia is actually used
Euphrasia is a technical or specialist term, encountered mainly in botany, herbalism, and homeopathy rather than everyday speech. In general writing, the common name 'eyebright' is more widely understood; when capitalized (Euphrasia) it denotes the botanical genus.
