Background

• An Indian native, vetiver is a perennial grass of the Poaceae family. In the scientific literature, vetiver is referred to as both Brazilian vetiver or vetivergrass (Vetiveria zizanioides) and vetiver (Chrysopogon zizanioides); these Latin names are considered synonymous.

• Tamil literature mentions the usage of vetiver for medical purposes and vetiver oil is commonly used in high-end perfumes. Currently, there is a lack of available high-quality clinical trials assessing the safety and efficacy of vetiver for any indication.
