Into the heart of Eyebright
Eyebright is a beautiful floral medicine with a long history of use for eye conditions. It is considered most specific to the eyes and was highly regarded by Herbalists of the sixteenth century.
Eyebright is used in all manner of eye conditions, as previously mentioned. It acts specifically on the mucous lining of the eyes and upper respiratory tract. Therefore it offers fast symptom relief for excess secretions relating to hay fever and air borne allergies.
Grieve (1984) mentions eyebright is not only to treat disease of the eye, but also as a tonic to this delicate sensory system, stating that there is some tradition to use as an occasional eye bath purely for its ability to tone the tissues, possibly helping to aid in dimness of sight.
Eyebright has a cooling effect, and in terms of Traditional Chinese Medicine, is considered sour- cooling and in action it offers a level of reduction in liver heat, this could also be backed by the presence of bitter constituents as bitter constituents directly increase liver function.
Eyebright has a long-standing use in herbal medicine and early records from the 14th century suggest it was used to ‘cure all evils of the eye’.
It was used for the treatment of eye conditions such an infections, conjunctivitis and blepharitis.
It has been used for a manner of mucous diseases, where stagnation and excess mucous present as symptoms.
Its ability to counter catarrh means it is often used for infectious and allergic conditions affecting the eyes, middle ear, sinuses and nasal passages. It seems to be a plant that has an infinity to the sensory organs of the head.
What practitioners say
Respiratory system: Eyebright is used for all manner of conditions relating to the nasal passages, allergic rhinitis, asthma and the common cold especially where excess mucous is a presenting symptom (2,3).
Both an antihistamine, astringent and anti-inflammatory, eyebright as an internal medicine (tea, tincture, capsule) is excellent for treatment of catarrh, hay fever, chronic sneezing, inflamed nasal mucosa, relaxed tonsils and sore throat, including where these symptoms are caused by allergy.
Specifically used to protect the eyes and mucosa during the catarrhal phase of measles, to avoid future problems (1,2).
Immune system: Eyebright is used for treating both infectious & allergic conditions affecting eyes, middle ear, sinuses & nasal passages.
Eyes: Due to its astringency and anti-inflammatory actions, eyebright is an effective treatment for conjunctivitis as an eye bath. It is also traditionally used in blepharitis, red eye, stye, for poor visual acuity due to eyestrain or diabetes and corneal opacity (1,3,5,6).
Skin: By alleviating oxidative stress, eyebright can be used topically, particularly to support cellular health following prolonged exposure to ultraviolet light (4).
In an in vitro study an extract of eyebright displayed cellular protection against UVB-induced photoaging by suppressing oxidative stress, cell apoptosis and inflammation. This preliminary study demonstrates the protective effects of E. officinalis against UVB-induced photoaging (4).
An in-vitro study analysing the activity of extracts of eyebright on cultured human corneal epithelial cells concluded promising effects in its application as treatment for eye disorders (5,6).
A number of compounds found in high concentration in eyebright, namely aucubin have been subject to extensive research, findings show anti microbial, hepatoprotective, antitumor and neuroprotective activity. Aucubin is found also in Ribwort Plantain (1).
It must be noted that despite longstanding traditional use, clinical trials on eyebright are limited and more research needs to be conducted. In vitro studies are not always a good reflection of the medical efficacy of a plant as results do not always translate into people. Nonetheless traditional use is a valid form of evidence too.
Did you know?
Eyebright was used by Ancient Greek physician Dioscorides for eye infections when accompanying Roman legions through many countries.
Eyebright is a semi parasitic annual plant that grows wild in grasslands, meadows, heaths, and pastures of Britain, Northern Europe, Western Asia and North America. Eyebright grows to a height of 4-8 inches (10-20 cm) and has small axillary odourless flowers which are usually white with purple streaks, red spots and a yellowish palate.
The leaves are opposite, ovate or cordate and strongly ribbed.
By the doctrine of signatures (a concept that states that botanical features of herbs may indicate their therapeutic applications) the petals of eyebright resemble bloodshot eyes, suggesting the plant’s name and its eye-clearing action. Downy hairs cover the stems, which produce toothed leaves.
Euphrasia (deriving from the Greek word euphrosyne meaning ‘gladness’.
The name eyebright both relates to the eye like appearance of the flower and its historic use in treatment of eye conditions.
Eyebright is safe to use long term, there are no reported interactions or contraindications (1).
Internal use: infuse 2-4g of dried herb in hot water, strain and drink. Up to three times daily.
Take 2-6ml of 1:5 tincture three times daily.
External use: Infusion. Using sterile equipment, infuse 1 heaped teaspoon of dried herb in half a cup of hot water for 10 minutes. Strain using a paper coffee filter (or similar, to remove all herb particles), cool, and drop into eyes. For inflammation or infection use bath eye for 10 seconds. Twice daily
