Vetiver, Vetiveria ziganoides, balances insufficient hormones . It has an earthy, woody aroma, which becomes very pleasant when combined with lavender absolute and labdanum absolute. Vetiver is a good base note for blends, a great fixative in perfumery. Vetiver is naturally calming and grounding. The aroma historically can reduce spasms, acne, vertigo and improve circulation. Vetiver blends well with Immortelle Frankincense, Tea tree, Tarragon, and herbal aromas. My favorite is to blend a few drops of Vetiver with several drops of Lavender absolute. After a few weeks, the scent is soft with a rich undertone. Dose lightly when used in blends with rose, geranium and/or Sandalwood. In a blend, vetiver can evolve into a dramatic scent . The essential oil is steam distilled from the root.
