Eyebright

Eyebright, also known as Euphrasia, is a genus of about 150 species of flowering plants in the family Orobanchaceae. The name "eyebright" comes from the plant's ability to improve vision, a belief that has been debunked by modern science. The genus is native to Europe, Asia, and North Africa, with a few species extending to North America. Eyebrights are perennial herbs, typically growing to a height of 10-50 cm. They have opposite, ovate leaves and showy, tubular flowers that are usually blue, purple, or white, often with a yellow throat. The flowers are arranged in whorls along the stem, and the plant produces a capsule fruit that contains numerous seeds. Eyebrights are often used in herbal medicine and traditional medicine, but their efficacy is not supported by scientific evidence. They are also cultivated as ornamental plants for their attractive flowers.
