Medicinal uses(Warning!)

Eyebright has a long history of herbal use in the treatment of eye problems and is still in current herbal use[2]. It is important that only the correct forms of eyebright, with glandular hairs on the calyx, are used, since other forms do not possess medicinal virtues[3]. Eyebright tightens the mucous membranes of the eye and appears to relieve the inflammation of conjunctivitis and blepharitis[4]. Its ability to counter catarrh means that it is often used for infectious and allergic conditions affecting the eyes, middle ear, sinuses and nasal passages[4].

The whole plant is anti-inflammatory, astringent, digestive, ophthalmic and slightly tonic[[2][1][5][6][7][8]. It is taken internally in the treatment of catarrh, sinusitis, hay fever, upper respiratory tract infections etc[9]. As an ophthalmic, an infusion of the plant can be taken internally or used as an eye wash. Alternatively, the diluted juice can be dropped into the eyes[10]. Some caution should be exercised, experimentally it can induce side effects including dim vision[11]. The plant's astringency makes it inappropriate for treating dry or stuffy congestion[4]. The plant can be used externally as a poultice to aid the healing of wounds[3]. Eyebright should be harvested when in flower and can be dried for later use[9]. The dried herb is a ingredient of herbal smoking mixtures, used in the treatment of chronic bronchial colds[2].

A homeopathic remedy is made from the expressed juice of the plant[10]. It is used particularly in the treatment of eye inflammations and colds[1][10].

Cultivation

Succeeds in most soils, preferring chalk or limestone[13]. Eyebright is a semi-parasitic plant, growing on the roots of various species of grass[2] and also on Trifolium pratense and Plantago species[9]. The grass does not seem to suffer unduly from this parasitism since eyebright is an annual and its cells do not penetrate very deeply into the grass[2].

There is some doubt over the validity of the name of this species, some botanists now call it Euphrasia rostkoviana.

Eyebright is a variable aggregate species, some botanists divide it into a number of different species[12][14]. Only those forms of eyebright which have glandular hairs on the calyx possess medicinal qualities[3]. It hybridizes freely with other members of this genus[13].
