Botanical Features

Vetiver is a dense grass that usually grows in large clumps. Its narrow, stiff leaves arise from the base, while the flowering stalk may grow much taller than the leaves. The plant produces a deep, dense network of fibrous roots that can penetrate far into the soil. These roots are highly aromatic and contain the valuable essential oil used in perfumes, cosmetics, soaps, and traditional preparations. Its strong root system makes it useful for stabilizing field boundaries, riverbanks, terraces, and slopes. It reduces runoff and helps control soil erosion, which is particularly valuable in the hilly landscapes of Nepal.

Uses

The dried roots of vetiver are commonly used to prepare fragrant screens, mats, fans, baskets, and small household products. When moistened, these roots release a pleasant cooling aroma and may be placed near windows or in water vessels. Vetiver root extract is also used to flavor beverages.

Vetiver oil is an important ingredient in perfumery because of its deep, earthy fragrance and ability to act as a fixative. It is also used in cosmetics, soaps, aromatherapy products, and herbal formulations. The leaves can be used for thatching, ropes, handicrafts, and limited livestock fodder.
