A plant common to the temperate regions of Europe, Asia and Africa, Agrimony grows modestly along roads, on banks and in clearings where its slender cluster of yellow flowers is easily recognised in the summer. The dried plant was a common remedy throughout the Middle Ages and was drunk as an infusion (wood tea) to enhance digestion, liberate the liver and kidneys and soothe soar throats. Recent studies have revealed the presence of flavonoids which ensure a vascular-protective action and especially remarkable stimulating properties on lymphatic circulation.
