Vetiver essential oil is steam distilled from the roots of Chrysopogon zizanioides, a perennial grass in the Poaceae family native to India and other parts of South and Southeast Asia. It is valued for its deep, earthy aroma, grounding character, and long-lasting scent.

Traditionally used in Ayurvedic and regional aromatic practices, vetiver oil has been associated with cooling, calming, and centering uses. It has also been used in perfumery and body care because its rich aroma helps anchor blends.

Vetiver is also known as vetivert, an older spelling still common in perfumery.
