Agrimonia species are used as food plants by the larvae of some Lepidoptera species including grizzled skipper (recorded on A. eupatoria) and large grizzled skipper.Agrimonia (from the Greek ργεμνη), commonly known as agrimony, is a genus of 12-15 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere, with one species also in Africa. The species grow to between .5-2 m (1.6-6.6 ft) tall, with interrupted pinnate leaves, and tiny yellow flowers borne on a single (usually unbranched) spike.
In the ancient times, it was used for foot baths and tired feet. Agrimony[specify] has a long history of medicinal use. The English poet Michael Drayton once hailed it as an "all-heal" and through the ages it was considered a panacea. The ancient Greeks used agrimony to treat eye ailments, and it was made into brews for diarrhea and disorders of the gallbladder, liver, and kidneys. Anglo-Saxons made a solution from the leaves and seeds for healing wounds; this use continued through the Middle Ages and afterward, in a preparation called eau d'arquebusade, or "musket-shot water". It can has been added to tea as a spring tonic. In the traditional Austrian medicine the herb has been used internally as tea for disorders related to the liver and bile, gastrointestinal, and respiratory tract. Agrimonia has been listed as one of the 38 plants that are used to prepare Bach flower remedies. According to Cancer Research UK, essences are not used to treat medical conditions.
Traditional British folklore states that if a sprig of Agrimonia eupatoria was placed under a person's head, they would sleep until it was removed.
