Description

Eyebright is a small annual, semi-parasitic herb native to Europe and parts of Asia and naturalized elsewhere. It typically grows 2–12 inches (5–30 cm) tall and bears delicate white to pale violet flowers marked with purple veins and a yellow center. The plant forms partial parasitic relationships with the roots of neighboring grasses and meadow plants, drawing a portion of its nourishment from surrounding vegetation.

The aerial parts are the medicinal portion used in traditional herbal medicine.

Taxonomic Note: The genus Euphrasia contains numerous closely related species and subspecies that can be difficult to distinguish botanically. Historically, many medicinal references group them under the traditional designation Euphrasia officinalis.

History & Tradition

Historical Overview

Eyebright has a long history in European herbal medicine and became one of the classic examples of the Doctrine of Signatures. Its flower markings were believed to resemble an eye, leading herbalists to associate it with vision and ocular health.

The herb appears in medieval herbals, Renaissance materia medica, and later European folk medicine traditions. By the sixteenth century, Eyebright was widely recommended by herbalists throughout Europe for conditions involving the eyes, head, and upper respiratory tract.

Its name derives from the Greek word euphrosyne, meaning joy, gladness, or delight, reflecting its historical reputation for brightening vision and perception.

Mrs. M. Grieve Notes

Maud Grieve describes Eyebright as one of the foremost traditional remedies for the eyes. She notes its longstanding reputation in European herbal medicine and records both internal and external applications.

Doctrine of Signatures

Eyebright is one of the most frequently cited examples of the Doctrine of Signatures in Western herbal literature. The flower's markings resemble a human eye, complete with radiating veins and a yellow center suggestive of the iris and pupil.
