Agrimonia Eupatoria Linn. Eupato-rium verum five agrimoni C. B. Agrimony: a hairy plant; with winged leaves, composed of oblong indented segments, with smaller portions between, set on middle ribs which (land alternately on the stalk: on the the top grows a long spike of pentapetalous yellow flowers, followed by little burs, containing, each, one or two seeds. It is perennial, grows wild in hedges and about the sides of felds, and flowers in May.
The leaves of agrimony have a slightly bitterish roughish taste, accompanied with an agreeable, though very weak, aromatic flavour: the flowers are in smell stronger and more agreeable than the leaves, and in taste somewhat weaker. They readily give out their virtues both to water and to rectified spirit: the leaves impart to the former a greenish yellow, to the latter a deep green colour: the flowers yield their own deep yellow tincture to both menstrua. In distillation with water, there arises a very small portion of a yellowish essen-tial oil, which smells strongly and agreeably of the herb.
Agrimony is one of the milder corroborants; and in this intention is sometimes employed, especially among the common people, against habitual diarrhoeas, and cachectic, and other indispositions from a lax state of the solids: in-fusions of the leaves, which are not ungrateful, may be drank as tea. It is sometimes joined with other ingredients in diet drinks for purifying the blood; and in pectoral apozems.
This plant is often raised in gardens; and does not seem to receive, from culture, any material change in its quality. Another species or variety, of foreign original, common also in our gardens, and differing little in appearance from our indigenous agrimony, promises to be superiour to it in virtue; as its taste is more aromatic, and its smell much stronger and very agreeable: Cafpar Bauhine calls it eupatorium odor atum, Fabius Columna eupatorium dioscoridis, odoratum & aromaticum.
