Khus: vetiver, the cooling root of Indian summers

Summer in a root

Before air conditioning, Indian homes hung wet khus screens in doorways. Air passing through them came out cool and scented with an earthy sweetness. Khus sherbet and khus attar carry the same scent.

The plant and the oil

Vetiver is a perennial grass with deep roots, also planted to hold soil against erosion. The roots are the valuable part: distilled, they give one of perfumery's deepest base notes. A 2024 review notes that vetiver oil has no synthetic substitute and is graded under Bureau of Indian Standards specifications.

What research shows

Reviews describe antifungal, antibacterial, antioxidant and anti-inflammatory activity in laboratory studies, and traditional uses in Ayurvedic, Thai and Chinese medicine. They also say active compounds and mechanisms still need validation. In body care we value khus first for its fragrance and the ritual it brings.

Khus in a home spa

• Add a body oil with vetiver to a warm bath.
• Use a khus-scented lepa as a cooling summer body pack.
• Pair it with rose water for a classic Indian scent.
