How To Identify Khas

Most people get confused between Khas and Khus Khus, but they are completely different. Khas is a fragrant grass with a sweet aroma and is commonly used in cosmetics and syrups while Khus Khus also popularly known as poppy seeds is obtained from the opium plant. Khas or vetiver is a tall herb with leaves that are long, slender, and coarse. This grass bunch that blooms with brownish-purple flowers has a gregarious nature. It always grows in clusters and unlike most grasses that spread horizontally, the root of this plant grows downward, 2 meters to 4 meters in depth. Khas is herbaceous and it being a climate-friendly crop, relies highly on rainfall.

The leaves and roots are mostly used for fragrance-filled syrups, decoctions, and herbal infusions besides treating many health anomalies. Leaves can grow up to five meters long and ten meters wide under clear water and can very easily survive up to three months. Because the roots penetrate deep into the soil and can sustain surface water, it is known to be one of the best plants to prevent soil erosion. Therefore this multifarious grass is of great use to farmers.
