Agrimonia, commonly known as agrimony, is a genus of 12–15 species of perennial herbaceous flowering plants in the family Rosaceae (order Rosales). Native to the temperate regions of the Northern Hemisphere, the genus extends across Europe, Asia, and North America, with one species also occurring in Africa.
Plants are upright perennials typically growing between 0.5 and 2 metres tall. The leaves are interrupted pinnate — meaning smaller leaflets are interspersed between the larger ones along the rachis — and the tiny yellow flowers are arranged in a dense, usually unbranched terminal spike. The fruits are small bur-like achenes that readily cling to passing animals and clothing, aiding seed dispersal.
The genus includes well-known members such as Agrimonia eupatoria (common agrimony), widely distributed across Europe, Asia, and northern Africa, and Agrimonia gryposepala (tall hairy agrimony), the most familiar North American species. Agrimonia procera (fragrant agrimony) is notable for its pleasant scent and is native to western and central Europe.
Agrimony has a long history of medicinal and cultural use. Ancient Greek physicians used it for eye complaints and digestive disorders, and Anglo-Saxon herbalists employed leaf and seed preparations for wound healing. This wound-wash tradition persisted through the Middle Ages under the name eau d'arquebusade ("musket-shot water"). The German Commission E (1990) recognises preparations of agrimony for mild acute diarrhea and superficial skin inflammation.
Etymology
The genus name Agrimonia derives from the ancient Greek ἀργεμώνη (argemone), a word used by Greek physicians for a plant with medicinal properties, particularly one used to treat ailments of the eyes.
Distribution
Agrimony species are native to the temperate regions of the Northern Hemisphere, with representatives in Europe, Asia (including eastern Asia and southwest Asia), and North America. Agrimonia pilosa extends across eastern Europe and Asia, while Agrimonia repens is centred in southwest Asia. One species also occurs in Africa.
Ecology
Agrimonia species serve as larval food plants for several Lepidoptera, including the grizzled skipper (Pyrgus malvae) and the large grizzled skipper, which have been recorded feeding on Agrimonia eupatoria. The bur-like fruits cling to animal fur and human clothing, facilitating epizoochorous (external animal-mediated) seed dispersal across the temperate landscapes the genus inhabits.
Cultural Uses
Agrimony has been used medicinally since antiquity. Ancient Greek physicians prescribed it for eye ailments and disorders of the gallbladder, liver, and kidneys. Anglo-Saxon healers boiled the plant in milk and made a solution from the leaves and seeds for treating wounds — a practice that continued through the Middle Ages as eau d'arquebusade ("musket-shot water"). The plant was also added to tea as a spring tonic, and the English poet Michael Drayton called it an "all-heal." The German Federal Commission E published a monograph in 1990 recognising agrimony preparations for mild acute diarrhea, oral and pharyngeal mucosa inflammation, and superficial skin inflammation.
