Research & Evidence
Achillicin is a guaianolide-type sesquiterpene lactone found in yarrow (Achillea millefolium). It is a proazulene, meaning it is converted during steam distillation into the blue compound chamazulene, which gives yarrow’s essential oil its characteristic blue color. Beyond its role as a chamazulene precursor, little about achillicin is well established.
