The root of the vetiver plant is used to make medicines. Vetiver is sometimes used by individuals that suffer from circulation and nerve problems. The essential oil is combined with a carrier oil and applied to the skin to help with relieving stress, shock, lice, and also with the repelling of insects. Vetiver can also be used in aromatherapy to help relieve nervousness, insomnia and muscle and joint pain. However, additional research should be conducted to fully understand the properties of the plant outside of medication manufacturing.
