Khus curtains, also known as "vetiver curtains" or "khus khus curtains," are a type of curtain traditionally made from the roots of the khus grass (Vetiveria zizanioides). These curtains are popular in some parts of South Asia and the Middle East. They are known for their cooling properties and pleasant fragrance.

Khus curtains are often hung in windows or doorways and are known for their ability to cool and freshen the air as it passes through them. The scent of the khus roots is released when the curtains are dampened or sprinkled with water, and the breeze passes through them, providing a natural and refreshing aroma.

These curtains are particularly popular in hot and arid regions because they can help lower the temperature in a room and provide a pleasant natural scent. They are also used for their aesthetic appeal and are sometimes considered a form of traditional home decor.
