Euphrasia stricta, the drug eyebright, is an annual forb in the genus Euphrasia . [1]
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, Minnesota and Illinois. [2] It is also found in Central Europe and Pyrenees [3]
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.
Euphrasia stricta is used in herbal medicine to treat inflammatory eye conditions, most notably allergic conjunctivitis. [4] The German Commission E did not consider there to be sufficient evidence to prove eyebright is useful for any condition. [5] Human clinical trials are lacking to support traditional claims, though absence of evidence is not proof of inefficacy.
Echinacea is a genus of herbaceous flowering plants in the daisy family. It has ten species, which are commonly called coneflowers. They are native only in eastern and central North America, where they grow in wet to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming in summer. The generic name is derived from the Greek word ἐχῖνος, meaning "hedgehog", due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Two of the species, E. tennesseensis and E. laevigata, were formerly listed in the United States as endangered species; E. tennesseensis has been delisted due to recovery and E. laevigata is now listed as threatened.
Actaea racemosa, the black cohosh, black bugbane, black snakeroot, rattle-top, or fairy candle, is a species of flowering plant of the family Ranunculaceae. It is native to eastern North America from the extreme south of Ontario to central Georgia, and west to Missouri and Arkansas. It grows in a variety of woodland habitats, and is often found in small woodland openings.
Chinese herbology is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A Nature editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action.
Salvia sclarea, the clary or clary sage, is a biennial (short-lived) herbaceous perennial in the genus Salvia. It is native to the northern Mediterranean Basin and to some areas in north Africa and Central Asia. The plant has long been cultivated as an herb and is currently grown for its essential oil.
Herbal medicine is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from Artemisia annua, a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of many plants used in 21st-century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine sometimes includes fungal and bee products, as well as minerals, shells and certain animal parts.
Traditional medicine comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement and treatment of physical and mental illness". Traditional medicine is often contrasted with Evidence based medicine.
A herbal is a book containing the names and descriptions of plants, usually with information on their medicinal, tonic, culinary, toxic, hallucinatory, aromatic, or magical powers, and the legends associated with them. A herbal may also classify the plants it describes, may give recipes for herbal extracts, tinctures, or potions, and sometimes include mineral and animal medicaments in addition to those obtained from plants. Herbals were often illustrated to assist plant identification.
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including defense and protection against insects, fungi, diseases, and herbivorous mammals.
Euphrasia, or eyebright, is a genus of about 215 species of herbaceous flowering plants in the family Orobanchaceae, with a cosmopolitan distribution. They are hemiparasitic on grasses and other plants. Both the common and generic names refer to the plant's use in a lotion for treating eye infections, with Euphrasia literally meaning 'good-cheer'.
Euphrasia arguta is a plant from the genus Euphrasia (eyebrights) within the family Orobanchaceae.
Officinalis, or officinale, is a Medieval Latin epithet denoting organisms—mainly plants—with uses in medicine, herbalism and cookery. It commonly occurs as a specific epithet, the second term of a two-part botanical name. Officinalis is used to modify masculine and feminine nouns, while officinale is used for neuter nouns.
Amblyptilia acanthadactyla, also known as the beautiful plume, is a moth of the family Pterophoroidea found in across the Palearctic including Europe. The species was first described by the German entomologist, Jacob Hübner in 1813.
Euphrasia gibbsiae is a perennial herbaceous plant in the genus Euphrasia. It is native to Victoria and Tasmania in Australia. Species in this genus may be called eyebright.
Euphrasia officinalis, also known as eyebright or eyewort, is a species of plant in the family Orobanchaceae.
HMCS Eyebright was a Flower-class corvette that served mainly with the Royal Canadian Navy during the Second World War in the Battle of the Atlantic. She was named after the medicinal flowering plant genus Euphrasia.
The history of herbalism is closely tied with the history of medicine from prehistoric times up until the development of the germ theory of disease in the 19th century. Modern medicine from the 19th century to today has been based on evidence gathered using the scientific method. Evidence-based use of pharmaceutical drugs, often derived from medicinal plants, has largely replaced herbal treatments in modern health care. However, many people continue to employ various forms of traditional or alternative medicine. These systems often have a significant herbal component. The history of herbalism also overlaps with food history, as many of the herbs and spices historically used by humans to season food yield useful medicinal compounds, and use of spices with antimicrobial activity in cooking is part of an ancient response to the threat of food-borne pathogens.
Euphrasia crassiuscula is a perennial herb in the genus Euphrasia. It is endemic to the Victorian Alps in Australia. The species was formally described by French botanist Michel Gandoger based on plant material collected by Carl Walter. Three subspecies are currently recognised:
Euphrasia vigursii, also known by its common names of Vigur's eyebright or Cornish eyebright, is an endangered annual of the eyebright family which is endemic to Devon and Cornwall. It is a facultative hemiparasite and needs open conditions and regular grazing of larger shrubs and grasses to grow. It is named after C. C. Vigurs, a Cornish doctor and botanist.
Euphrasia semipicta, commonly known as the Peninsular eyebright, flowering plant endemic to the Tasman Peninsula in south-eastern Tasmania/ luturwita.
