Yarrow oil (Achillea Millefolium)
Yarrow oil is extracted from Achillea millefolium, a member of the Compositea plant family. This perennial herb is known throughout Europe, but also grows in Asia and North America. Yarrow can grow up to three feet (one meter) high, and is distinguishable by its feathery and aromatic fern-like leaves, and pink-white, dense flower heads.
Yarrow oil is extracted from the dried plant via steam distillation. When diffused, it has a sweet, herbaceous, and penetrating smell. It also develops a vivid blue color when distilled, which occurs when the chemical chamazulene is released from the plant material during the heating process.
The main chemical components of yarrow oil are tricyclene, a-pinene, camphene, b-pinene, sabinene, borneol acetate, 1,8-cineole, y-terpinene, limonene, isoartemisia ketone, borneol, camphor as well as traces of chamazulene - giving the blue color.
The therapeutic properties of yarrow oil are anti-inflammatory, antirheumatic, antiseptic, antispasmodic, astringent, carminative, cicatrisant, diaphoretic, digestive, expectorant, haemostatic, hypotensive, stomachic and tonic.
Yarrow oil can improve circulatory disorders such as varicose veins and hemorrhoids. It helps with irregular menstruation, menopausal problems, cystitis and infection.
