Drug eyebright euphrasia stricta 2013 06 23
Euphrasia stricta or drug eyebright is an annual forb in the genus Euphrasia.
Contents
It has been introduced in northeastern North America, where it is found in New England (except Connecticut), New York, Pennsylvania, Nova Scotia, New Brunswick, Prince Edward Island, Ontario, Quebec, the upper peninsula of Michigan, northern Wisconsin, and Illinois.
The preferred growing location is on moist, calcareous sands, such as those on some moors and dunes. The plant is a hemiparasite and can steal water and salts from grasses.
Uses
Euphrasia stricta is used in herbal medicine to treat inflammatory eye conditions, most notably allergic conjunctivitis. The German Commission E did not consider there to be sufficient evidence to prove eyebright is useful for any condition. Human clinical trials are lacking to support traditional claims, though absence of evidence is not proof of inefficacy.
