Multiple applications of vetiver grass – a review

Abstract: Since ancient times, vetiver grass and its roots are well known for their fragrance, medicinal and soil erosion control properties. Native to India, vetiver is a perennial grass that grows up to 2 meters in height and the roots grows up to 3 meters deep. They can grow in harsh conditions with limited water availability or in drought conditions. The roots hold plenty of soils, which encourages using this grass as a soil conservation tool in erosion prone areas. Several soil conservation sites have been successfully implemented using vetiver grass in several countries such as Haiti, Philippines and Thailand. In addition, the aromatic oil present in the roots of vetiver is used in perfumery and holds a very high commercial value. On the other hand, several research studies over the past years prove that vetiver grass could be used in other applications such as bioremediation of toxic wastes, farm hedges, termite control, household handicrafts, composites and herbal medicine. This work presents a compilation of research studies related to vetiver applications, policy recommendation, limitations and potential large-scale applications.
