Achillea santolina

Achillea santolina is a perennial herb of dry ground in Iraq and Jordan, which can also settle in colder, damper parts of Europe and Asia. It stands 15 to 30 cm tall, with erect or rising stems and green leaves cut into three flat, toothed lobes. Its flowers form slightly domed, radiate heads on long stalks and open from March to April, on the edges of cultivated land. Wikipedia lists flavonoids and sesquiterpene lactones as its main constituents, and gives camphor and 1,8-cineole as the chief parts of the essential oil. In Iraq and Jordan an infusion of the leaves is drunk for intestinal colic, dysentery and wind. In Turkey the plant is used for abdominal pain, stomach-ache and surface wounds. Externally it has been used as a sitz bath or compress for inflamed or irritated skin, and the dried aerial parts are taken for colds. The page reports that domestic flies and honeybees responded significantly to the plant's insecticidal and repellent activity. The page calls these medicinal uses traditional and still under research.
