Using GC/MS we examined the oils of Achillea clavenae, A. collina and A. lingulata. A. clavenae oil contained high levels of camphene (29.6%) and bornyl acetate (10.8%), A. collina was rich in 1,8-cineole (27.6%), chrysanthenone (8.5%) and camphor (9%), while A. lingulata contained borneol (20.3%) as the major constituent. Although these compounds occur in many varieties, their levels are characteristically high in these oils.
