Vetiver is sometimes applied directly to the skin for relieving stress, as well as for emotional traumas and shock, lice, and repelling insects. It is also used for arthritis, stings, and burns. Vetiver is sometimes inhaled as aromatherapy for nervousness, insomnia, and joint and muscle pain. Just put some vetiver (lavancha roots) it in a pitcher, a glass bottle or a clay pot and let them steep for at least 2 to 4 hours before drinking. How many vetiver roots to infuse in water? Infuse around 6-8 strands for about 1L of water. This can also be a great addition for your summer lemonades or coolers
