Common Uses in Dogs
Eyebright
Euphrasia officinalis
(Snapdragon family)
This herb tightens the mucous membranes of the eye and is therefore most effective for treating
eye problems, in particular, chronic inflammation, stinging and weeping eyes, and photosensitive eyes.
Due to the herb's ability to counter mucous, it is also often used to treat allergic conditions affecting the eyes, middle ear, sinuses, and nasal passages.
It can be taken internally as a tea or tincture, or used externally as an eyewash or compress.
Availability
Various preparations of the herb (such as tincture, water infusion) are available at health food stores.
