Soil binding aromatic crops is Vetiver.
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.
The roots are woven into mats, and hand fans and are also used in air coolers. Vetiver is planted in sloppy areas to prevent soil erosion as it binds with the soil.
