The note of Ruh Khus, often hailed as the "Vetiver of India," presents an extraordinarily deep, earthy, and smoky olfactory profile. It possesses a raw, unadulterated character, reminiscent of rich, damp soil after a monsoon, intertwined with the scent of ancient, moss-covered roots and a distinct, almost primal smokiness. Unlike its Haitian or Javanese counterparts, Ruh Khus carries less of a bright, citrusy top note or a sharp, metallic edge; instead, it plunges directly into profound, verdant earthiness, with a subtle yet persistent leathery nuance. Its texture is dense, almost viscous, projecting a powerful yet incredibly grounding aura. It evolves slowly, revealing subtle hints of nuttiness and a dry, almost mineralic warmth as it settles. As a quintessential base note, it offers exceptional longevity and tenacious sillage, anchoring compositions with its profound depth and complexity for many hours, sometimes even days.
