Eyebright is a member of the figwort family that is original to Europe
but now inhabits most of the globe. Its genus name is adapted from the
Greek word for “gladness,” while its common name is a reference to its
traditional use since the 14th century for various disorders of the eye.
The astringent qualities of eyebright are used to address congestion,
sinusitis and other issues relating to inflammation of the mucous
membranes. In addition to poultices, lotions and eye washes, eyebright
is added to syrups and throat lozenges. The herb is also listed as an
official ingredient in the Homeopathic Pharmacopœia of the United
States.
