Khas khas

Khas Khas or Vetiver (Vetiveria zizanioides) is a perennial grass of the Poaceae family, native to India. It is known for its deeply penetrating roots and its dense curtain of leaves. Khas Khas is used extensively in perfumery, for its fixative qualities and its pleasant, earthy aroma.

Etymology

The term "Khas Khas" is derived from the Persian word "خس خس" which means "like straw". The term "Vetiver" is derived from the Tamil word "வெட்டிவேர்" (Vettiver), which means "root that is dug up".

Description

Khas Khas grows up to 1.5 meters high and forms clumps as wide. The stems are tall and the leaves are long, thin, and rather rigid. The flowers are brownish-purple. Unlike most grasses, which form horizontally spreading, mat-like root systems, Khas Khas roots grow downward, 2–4 m in depth.

Cultivation

Khas Khas is cultivated for the fragrant essential oil that is distilled from its roots. The plant is essentially wild, but it is also cultivated in India, Haiti, and Indonesia. The world's major producers are Haiti and India.

Uses

Khas Khas has a variety of uses. The essential oil is used in perfumery and aromatherapy. The roots are woven into mats and screens, and the leaves are used for thatching. In traditional medicine, Khas Khas is used as a carminative and as a cooling agent.

Environmental Impact

Khas Khas is also used in soil conservation programs because its roots bind the soil, preventing erosion. It is also used in wastewater treatment, as it can absorb heavy metals and other pollutants.
