Yarrow Essential Oil is also known as Milfoil Essential Oil. Yarrow (Achillea millefolium) is an aromatic, rhizomatous perennial herb with one to several stems reaching up to about three feet in height. The leaves are very finely dissected, with a feathery, lacy appearance giving rise to the plant’s folk name “thousand leaf”. The plants bear dense, generally white and occasionally pinkish white composite flower heads. Depending on location, flowering generally occurs between May and September and as the flowers rise and bloom, the leaves shrink back and become small. Many cultivars of A. millefolium have larger and more colorful flowers and are grown as garden ornamentals but don’t have the medicinal potency of the original plant.
Yarrow Essential Oil is produced by steam distillation of the dried, flowering herb. It contains a constituent known as chamazulene, which has been reported to reduce inflammation and which imparts a blue color to the essential oil. The aroma is penetrating and herbal. In the practice of aromatherapy, Yarrow Essential Oil has been used for it’s claimed ability to support those experiencing a wide variety of complaints, including colds, digestive upsets and nervous exhaustion.
