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 as was drunk as an infusion (wood tea) to enhance digestion, liberate the liver and kidneys and soothe soar throats. Recent studies in China revealed a specific action on blood circulation. Clarins uses it for the first time in cosmetology. Its rich PCO (ProanthoCyanidine Oligomers) content (found in other plants like grape) gives it a vascular-protective action and especially remarkable stimulating properties on lymphatic circulation.
