The common agrimony (Agrimonia eupatoria) is a herbaceous plant belonging to the rose family (Rosaceae). This plant, with its bright yellow flowers in long, slender spikes, is quite common on calcareous roadsides and dikes in Belgium and the Netherlands.
In herbal medicine, this plant is used for various purposes due to its active constituents, including triterpenes, tanning and bitter substances, flavonoids, silicic acid and mucilages.
The most common use is as a tea, but the herb can also be made into a tincture.
